A ball is thrown into the air. Its height (in feet) t seconds later is given by h(t)=64t−16t^2 a) What is the height of the ball 1 second after it has been thrown? b) After how many seconds does the ball hit the ground? c) At what time(s) is the ball 30 feet above the ground?
Answer:
A) 48 feet
B) 4 seconds
C) 0.54 seconds and 3.46 seconds
Step-by-step explanation:
So we have the function:
[tex]h(t)=64t-16t^2[/tex]
Which represents the height h(t) of the ball after t seconds.
A)
To find the height of the ball 1 second after it has been thrown, substitute 1 for t. Thus:
[tex]h(1)=64(1)-16(1)^2[/tex]
Simplify:
[tex]h(1)=64-16[/tex]
Subtract:
[tex]h(1)=48[/tex]
So, after 1 second, the height of the ball is 48 feet above the ground.
B)
To find out how many seconds after being thrown does the ball hit the ground, we'll set h(t) to 0. 0 means that it will be 0 feet above ground level: in other words, on the ground. So:
[tex]0=64t-16t^2[/tex]
Solve for t. Factor out a 16t:
[tex]0=16t(4-t)[/tex]
Zero Product Property:
[tex]16t=0\text{ or } 4-t=0[/tex]
Solve for t:
[tex]t=0\text{ or } t=4[/tex]
We'll ignore the first zero. So, the ball lands after 4 seconds of being thrown into the air.
C)
To find out at what time(s) the ball is 30 feet above the ground, set h(t) to 30 and solve for t:
[tex]30=64t-16t^2[/tex]
First, divide everything by 2 to simplify things:
[tex]15=32t-8t^2[/tex]
Subtract 15 from both sides:
[tex]-8t^2+32t-15=0[/tex]
Now, to find the zeros, we can use the quadratic formula. a is -8, b is 32, and c is -15. Thus:
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
Substitute:
[tex]x=\frac{-32\pm\sqrt{32^2-4(-8)(-15)}}{2(-8)}[/tex]
Simplify:
[tex]x=\frac{32\pm\sqrt{544}}{16}[/tex]
Use a calculator. Approximate:
[tex]x\approx0.5422\text{ or } x\approx 3.4577[/tex]
So, the ball is 30 feet above the ground after 0.54 seconds and 3.46 seconds.

The enrollment in fall 1993 was 14.3 million. If you were to use the model of 1993 what would the enrollment be?
Answer:
Why is college important? It’s a question you may have heard among friends, or perhaps you’ve even wondered yourself about the benefits of earning a degree. And it’s a good question to be asking as you consider your future—and everything that will include, from earnings potential to starting or switching your career. Here are five facts you should know as you consider the value of a college education.
1. People with college degrees earn more on average.
According to averages calculated by the US Bureau of Labor Statistics (BLS), people with a bachelor’s degree earn around 64% more per week than individuals with a high school diploma, and around 40% more than those with an associate’s degree. Those with an associate’s degree earn around 17% more than those with a high school diploma.
Over the course of a year (52 weeks), those percentage differences add up. For example, if you compare the average median annual earnings for those with a bachelor’s degree to those with a high school diploma, you’ll discover a difference of almost $24,000 per year in income.
2. College can help you expand your network.
Salary is far from the only answer for why is college important. You may have heard this before, but who you know and who your friends know is important. No matter how talented you are, a strong network can help you start and advance in your career.
At an Art Institutes school, you’ll not only have the chance to connect with instructors* who have worked in their fields, but you can also meet students in a variety of creative fields. These diverse connections may well benefit you in the future. Plus, you can also participate in professional groups, community activities, and industry conferences where you can grow your circle even more. Your Career Services department may also connect you with alumni in your field and can continue to provide networking support after graduation!
3. Gaining new skills can help enhance your current career.
Building your skill set and industry knowledge can help you move forward in your current career, and the skills you learn go beyond the obvious. At The Art Institutes, not only can you build your technical and artistic skills, but you can also develop your critical thinking, communication, and teamwork.
Earning your degree can demonstrate to a current employer that you’re serious about your career, and that you’re prepared to take on bigger projects and more responsibility. In the long term, when you apply to new jobs in your field, having a degree can provide you with a competitive edge. Even if the job doesn’t require a degree, your education—along with the quality of your work—may help you stand out among applica

How do you do letter b?
Answer: 175
Step-by-step explanation:
[tex]g(35)= \int\limits^{35}_0 {f(x)} \, dx =\int\limits^{30}_0 {f(x)} \, dx +\int\limits^{35}_{30} {f(x)} \, dx[/tex]
= 137.5 + 37.5
= 175
Answer:
g(35) = 137.5
Step-by-step explanation:
g(35) = g(30) + [g(35) - g(30)]
g(35) = 100 + 5(15)/2
g(35) = 137.5
Circle B is shown. Line segments C B, D B, and E B are radii and they form 3 congruent angles. What does Arc C D E describe? a minor arc a major arc a semicircle a chord
Answer:
a major arc
Step-by-step explanation:
A circle is the locus of point in which has a given distance from a fixed point (center of the circle).
B is the center of the circle C B, D B, and E B are radii forming 3 congruent angle. Since the sum of angles in a circle is 360°, the 3 line segments form 3 congruent angles of 120° each (360/3).
Therefore the angle measure of Arc C D E = Arc CD + Arc DE = 120° + 120° = 240°
A major arc is an arc greater than a semicircle (> 180°). This means that Arc C D E is a major arc

Which of the following is an example of stratified sampling when obtaining a sample of 100 high school students? A. Choosing 100 students at random from a specific grade level at a high school.B. Choosing 100 students sitting in one random section of the cafeteria at a high school.C. Choosing 25 students at random from each of four different grade levels at a high school.D. Choosing 100 students at random from a high school. E. Choosing 100 students at random from an AP Statistics class at a high school.
Answer:
Option C - Choosing 25 students at random from each of four different grade levels at a high school
Step-by-step explanation:
For us to achieve the conditions for a stratified random sample, the target population must be split into different groups which in this case, it's grade levels.
Looking at the 5 options given in the question, Options A, B, D and E are random but they are not truly stratified in their sampling approach. This is because the sample population must be selected at random from each of these groups and it's only option C which is choosing 25 students from each of four different grade levels or groups that reflects that.

On Sunday, the temperature dropped 24° in 6 hours. What was the average change in temperature per hour?
Answer:
The temperature drops 4° every hour
Step-by-step explanation:
Step 1:
24° ÷ 6
Step 2:
24 : 6 = 4 : 1
Answer:
4
Hope This Helps :)
Answer:
[tex]\boxed {\tt -4 \textdegree \ per \ hour }[/tex]
Step-by-step explanation:
This question asks us to find the average rate of change in temperature per hour.
Therefore, we must divide the temperature change by the hours.
[tex]rate \ of \ change =\frac{temperature \ change}{hours}[/tex]
The temperature dropped 24 degrees in 6 hours. Since it dropped, the change was negative.
[tex]temperature \ change = -24 \textdegree \\hours = 6 \ hours[/tex]
Substitute the values into the formula.
[tex]rate \ of \ change =\frac{-24 \textdegree}{6 \ hours}[/tex]
Divide.
[tex]rate \ of \ change = - 4 \textdegree / hour[/tex]
The average change in temperature was -4° per hour. The temperature dropped 4 degrees each hour.

A total of 6.2 percent of the prime time viewing audience watched shows on ABC, 8.1 percent watched shows on CBS, 7.4 percent on Fox, 6.4 percent on NBC, 3.1 percent on Warner Brothers, and 2.8 percent on UPN. A total of 66 percent of the audience watched shows on other cable networks, such as CNN and ESPN.
What will be the prime time viewing percentage of the pie chart for the following data? (Only consider the viewers watching non-cable news.) (Round your answers to 2 decimal places.)
Answer:
For each one it is shown below
Step-by-step explanation:
The computation of the prime time viewing percentage for the following data is shown below:l;
but before that we need do the total which is
= 6.2% + 8.1% + 7.4% + 6.4% + 3.1% + 2.8%
= 34%
Now for each one the viewing percentage is
For ABC
[tex]= \frac{6.2}{34}[/tex]
= 18.24%
For CBS
[tex]= \frac{8.1}{34}[/tex]
= 23.82%
For NBC
[tex]= \frac{6.4}{34}[/tex]
= 18.82%
For Warner brothers
[tex]= \frac{3.1}{34}[/tex]
= 9.12%
For fox
[tex]= \frac{7.4}{34}[/tex]
= 21.76%
For UPN
[tex]= \frac{2.8}{34}[/tex]

The total cost C (in dollars) of playing an online game is given by the literal equation C = 30x + 50, where x is the number of months you play the game. Solve the equation for x. How many months do you play the game when you spend $170? $260?
Answer:
4 months and 7 months
Step-by-step explanation:
C = 30x + 50
C is cost so when we spend $170 we can solve for x.
$170 = 30x + 50
170 - 50 = 30x + 50 - 50
170 - 50 = 30x
120 = 30x
120/30 = 30x/30
120/30 = x
4 = x
So he has played 4 months when he spends $170
C is cost so when we spend $260 we can solve for x.
$260 = 30x + 50
260 - 50 = 30x + 50 - 50
260 - 50 = 30x
210 = 30x
210/30 = 30x/30
210/30 = x
7 = x
So he has played 7 months when he spends $260
Find an equation of the line having the given slope and containing the given point. m=-5 (5,7)
Answer:
y = -5x + 32
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Write in known variables
slope m = -5
y = -5x + b
Step 2: Find b
7 = -5(5) + b
7 = -25 + b
b = 32
Step 3: Write linear equation
y = -5x + 32
Answer:
y - 7 = -5(x - 5)
Step-by-step explanation:
Pre-SolvingWe are given that a line has a slope of -5 and contains the point (5,7).
We want to write the equation of this line.
The equation of this line can be written in three ways:
Point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1,y_1)[/tex] is a point.Standard form, which is ax+by=c, where a, b, and c are free integer coefficients. Slope-intercept form, which is y=mx+b, where m is the slope and b is the value of y at the y intercept.Either one of these ways works, but let's use point-slope form, as that form is the easiest.
SolvingWe can immediately substitute the values into the formula to get the equation.
We can start with the slope; replace m with -5 in the formula.
[tex]y-y_1=m(x-x_1)[/tex] => [tex]y-y_1=-5(x-x_1)[/tex]
Now, we can replace [tex]x_1[/tex] and [tex]y_1[/tex] with 5 and 7 respectively to get:
y - 7 = -5(x - 5)

Answer:
{ 9 , 10 }Option A is the correct option.
Step-by-step explanation:
Let the sets be A and B
A = { 7 , 8 , 9 , 10 }
B = { 9 , 10 , 11 , 12 }
The intersection of sets A and B is the set of all ements which belongs to both A and B.
The intersection of sets A and N is denoted by ( A ∩ B ) and read as A intersection B.
A ∩ B = { 7 , 8 , 9 , 10 } { 9 , 10 , 11 , 11 , 12 }
Now, list the elements which are present in both sets. A ∩ B = { 9 , 10 }

Step-by-step explanation:
Let u = (−2, 3, 1), v = (−1, −1, 2), and 3u − 2v − 4w = (3, 2, −3). Find: a. The vector w.b. -2u + 3v - 5w
Answer:
(a) w = [tex](\frac{-7}{4} , \frac{9}{4}, \frac{1}{2})[/tex]
(b) -2u + 3v - 5w = ([tex]\frac{39}{4}[/tex], [tex]\frac{-54}{4}[/tex], [tex]\frac{3}{2}[/tex])
Step-by-step explanation:
Given:
u = (−2, 3, 1)
=> u = -2i + 3j + k --------------------------(i)
v = (−1, −1, 2)
=> v = -i - j + 2k --------------------(ii)
3u − 2v − 4w = (3, 2, −3)
=> 3u − 2v − 4w = 3i + 2j - 3k ------------------(iii)
(A) TO FIND THE VECTOR w
Let:
w = (a, b, c) = ai + bj + ck
(a) Substitute u, v and w into equation (iii)
3u − 2v − 4w = 3i + 2j - 3k
3(-2i + 3j + k) - 2(-i - j + 2k) - 4(ai + bj + ck) = 3i + 2j - 3k
(b) Solve the equation in step (a) by opening the brackets and collecting like terms
(-6i + 9j + 3k) - (-2i - 2j + 4k) - (4ai + 4bj + 4ck) = 3i + 2j - 3k
open brackets
-6i + 9j + 3k + 2i + 2j - 4k - 4ai - 4bj - 4ck = 3i + 2j - 3k
collect like terms
-6i + 2i - 4ai + 9j + 2j - 4bj + 3k - 4k - 4ck = 3i + 2j - 3k
i(-4 - 4a) + j(11 - 4b) + k(-1 - 4c) = 3i + 2j - 3k
(c) Solve for a, b and c in step (b)
Comparing both sides of the equation, we have;
-4 - 4a = 3 ----------(*)
11 - 4b = 2 -----------(**)
-1 - 4c = -3 ------------(***)
From (*)
4a = -4 - 3
4a = -7
a = [tex]\frac{-7}{4}[/tex]
From (**)
4b = 11 - 2
4b = 9
b = [tex]\frac{9}{4}[/tex]
From (***)
-1 - 4c = -3
4c = -1 + 3
4c = 2
c = [tex]\frac{2}{4}[/tex]
c = [tex]\frac{1}{2}[/tex]
Remember that
w = (a, b, c)
w = ai + bj + ck
Therefore,
w = [tex](\frac{-7}{4} , \frac{9}{4}, \frac{1}{2})[/tex]
(B) TO FIND -2u + 3v - 5w
Remember that;
u = (−2, 3, 1)
v = (−1, −1, 2),
w = [tex](\frac{-7}{4} , \frac{9}{4}, \frac{1}{2})[/tex]
Substitute u, v, w into the expression as follows;
-2(−2, 3, 1) + 3(−1, −1, 2) - 5[tex](\frac{-7}{4} , \frac{9}{4}, \frac{1}{2})[/tex]
Expand
(4, -6, -2) + (−3, −3, 6) - [tex](\frac{-35}{4} , \frac{45}{4}, \frac{5}{2})[/tex]
Collect like terms
(4-3+[tex]\frac{35}{4}[/tex], -6-3-[tex]\frac{45}{4}[/tex], -2+6-[tex]\frac{5}{2}[/tex])
Solve
([tex]\frac{39}{4}[/tex], [tex]\frac{-54}{4}[/tex], [tex]\frac{3}{2}[/tex])
Therefore, -2u + 3v - 5w = ([tex]\frac{39}{4}[/tex], [tex]\frac{-54}{4}[/tex], [tex]\frac{3}{2}[/tex])

Look at the graph. On a coordinate plane, a graph increases through (negative 1, 4), levels off at (0, negative 3), and then increases up through (2, 5). Leslie analyzed the graph to determine if the function it represents is linear or non-linear. First she found three points on the graph to be (–1, –4), (0, -3), and (2, 5). Next, she determined the rate of change between the points (–1, –4) and (0, -3) to be StartFraction negative 3 minus (negative 4) Over 0 minus (negative 1) EndFraction = StartFraction 1 Over 1 EndFraction = 1. and the rate of change between the points (0, -3) and (2, 5) to be StartFraction 5 minus (negative 3) Over 2 minus 0 EndFraction = StartFraction 8 Over 2 EndFraction = 4. Finally, she concluded that since the rate of change is not constant, the function must be linear. Why is Leslie wrong? The points (–1, –4), (0, –3), and (2, 5) are not all on the graph. The expressions StartFraction negative 3 minus (negative 4) Over 0 minus (negative 1) EndFraction and StartFraction negative 3 minus (negative 5) Over 2 minus 0 EndFraction both equal 1. She miscalculated the rates of change. Her conclusion is wrong. If the rate of change is not constant, then the function cannot be linear.
