The function g(t)=−16t2+vt+h represents the height of an object, g, in feet, above the ground in relation to the time, t, in seconds, since the object was thrown into the air with an initial velocity of v feet per second at an initial height of h feet. A model rocket is launched off the ground at an initial velocity of 80 feet per second. Part A: Write a function that can be used to describe the flight of the model rocket. Part B:What domain makes sense for this function in context?
Answer:
A) g(t) = - 16*t² + 80*t
B) domain is ( 0 ≤ t ≤ 5 )
Step-by-step explanation:
A) for the model rocket
h = 0 and v = 80 feet/sec
Then the equation g(t) = -16*t² + v*t + h
became
g(t) = - 16*t² + 80*t + 0 g(t) = - 16*t² + 80*t
B) The equation g(t) = - 16*t² + 80*t is defined for all real numbers then the domain interval for t is ( -∞ , ∞ ). Now in our case, a model rocket was launched is not possible to get negative values for g(t) then the biggest value for t = 5 from
-16*t² + 80*t ≥ 0
-16*t ≥ -80 16*t ≤ 80
t ≤ 5
And the domain is ( 0 ≤ t ≤ 5 )
What is the first step in simplifying the expression below ?
3 + 4 (6 - 8)^2
O 3 Plus 4
O 3 Plus 16
O 6 Minus 8
O Multiply -2 by itself
O Multiply by 4
Answer:
Step-by-step explanation:
The very first step is to take (6 - 8) = - 2 Do the brackets first.
Now square the result (-2)^2 = 4 Multiply by 4
4*4 = 16 These fours are different. The first is the brackets, The second is what is out side the brackets.
Last step: 16 + 3 The answer is 19.
19 is not what you asked for, but it's a good idea to see how to continue.

A piece of land is 3 miles wide. It is 4 1/6 times as long as it is wide. How long is the piece of land?
Answer: [tex]\frac{25}{2}\ \text{miles}[/tex]
Step-by-step explanation:
Given
A piece of land is 3 miles wide
It is [tex]4\ \frac{1}{6}[/tex] times as long as it is wide
Suppose width be b
So, length becomes [tex]\frac{24+1}{6}b[/tex]
Also, [tex]b=3\ \text{miles}[/tex]
[tex]\therefore \text{Length is }l=\dfrac{25}{6}\times 3\\\\\Rightarrow l=\dfrac{25}{2}\ \text{miles}[/tex]

john bought 3 1/2meters of wire it he used 1 5/6 meters in wire a job how many meters of qire was leftover
Answer:
1 (2/3)meter
Step-by-step explanation:
3(1/2) = 7/2 = 21/6
1(5/6) = 11/6
21/6 - 11/6 = 10/6 = 5/3 = 1 (2/3)
How do I solve this problem?
Answer:
21, 18, 15
Step-by-step explanation:
First term = a1
Second term = a2
Third term = a3
a1 = 21
a2
= a + d
= 21 - 3
= 18
a3
= a + 2d
= 21 + 2 ( - 3 )
= 21 - 6
= 15
The first 3 terms are 21, 18, 15.

h(v)=5v2–28v+11, use synthetic division to find h(4).
Answer:
h(4)=-21
Step-by-step explanation:
h(v)=5x^2-28v+11
h(4)=5(4)^2-28(4)+11
h(4)=5(16)-112+11
h(4)=80-101
h(4)=-21

in class slope and y intercept 50 points
Answer:
Slope =-3, y intercept =4
Step-by-step explanation:
y2-y1/x2-x1 = slope
4-(-2)/0-2=6/-2 or -3
y intercept is where line crosses y axis so it is 4.
Answer:
Slope: -3, y-intercept: 4
Explanation:
=> In order to find slope when a graph is given, the formula would be: [tex]\frac{rise}{run}[/tex](pronounced as "rise over run")
Rise = change in y-value = -3
Run = change in x-value = 1
Slope = [tex]\frac{rise}{run}[/tex] = [tex]\frac{-3}{1}[/tex] also could be written as -3
=> Now, to find the y-intercept, find a value on the graph where the line touches the y-axis, that's where x = 0, which would be your y-intercept;
Here the line touches the y-axis at "y = 4", this is also where x = 0;
therefore y-intercept = 4

A candle on a table is 6 inches tall and burns at a rate of .8 inches per hour. How many hours will it take for the candle to burn down to a height of 1.2 inches?
Answer:
6 hours
Step-by-step explanation:
6 inches burns at rate .8 inches in 1 hour
to be 1.2 inches has to burn 6 -1.2 = 4.8 inches of the candle
4.8 inches / .8 inches in 1 hour = 6 hours

3.072 > 3.2
728.307 > 729.07
12.040 = 12.04
531.135 < 531.315
Answer:
No, no, yes, yes
Step-by-step explanation:
3.072 is not bigger than 3.2, so incorrect (no)
728.307 is not bigger than 729.078, so incorrect again (no)
12.040 does equal 12.04, so correct (yes)
531.135 is smaller than 531.315, so correct (yes)
In a standard deck of card there are 52 cards total. Find the number of possible 5 hand cards that contain 3 queens and 2 kings.
Answer:
The probability of choosing 3 kings and 4 queens out of the 8 (4+4) kings and queens is given by 0.42857
Step-by-step explanation:
There are 4 queens and 4 kings in a deck of 52 cards. So we have to choose 5 cards having 3 queens and 2 kings out of the 52
Therefore the combinations can be written like this 8C5= 56 ways
And the probability this can be chosen is given by
4C3*4C2/8C5
=4*6/56
=24/56
=0.42857
The probability of choosing 2 kings and 3 queens out of the 8 (4+4) kings and queens is given by 0.42857 or 24/56
Help ASAP! It’s due and thanks
Answer:
C
Step-by-step explanation:
It can't be B or D, because there is only a difference in the X axis (Meaning it goes either left or right)
It can't be A because 2 is less than 11, so (2, -1) would be left 9 units in relation to (11, -1)

The population of a swarm of killer bees multiplies
10 fold in 50 days. Determine the correct
expression to calculate the number of bees after t
days if the initial swarm had 1000 bees.
Answer:
The correct expression to calculate the number of bees after t days if the initial swarm had 1000 bees is [tex]P = 1000 *e^{0.2*t}[/tex]
Step-by-step explanation:
Given -
The population of a swarm of killer bees increases by 10 times in 50 days
The rate of increase of population is [tex]r = \frac{10}{50} = 0.2[/tex] per day
As we now the equation of population projection is
[tex]P= P_0 *e^{rt}\\[/tex]
Where P0 = initial population
P is the population after time t
and r is the rate of increase of population
Substituting the given values in above equation, we get -
[tex]P = 1000 *e^{0.2*t}[/tex]

Answer:
1.9
Step-by-step explanation:
just put it into he calculator, because with 3 above the square root.
Answer:
Approximately 1.9 (rounded to the nearest tenth)
Step-by-step explanation:
First, we are left off with the equation:
[tex]y^{3} = 7[/tex]
We know we want to solve for y. So, let's do the opposite of what is being done to y. In other words, let's find the cube root of [tex]y^{3} = 7[/tex].
[tex]\sqrt[3]{y^3} = \sqrt[3]{7}[/tex]
Then, the [tex]\sqrt[3]{y^3}[/tex] just simplifies to y. On the other side, we cannot find the cube root of 7 in our minds, so that is why it tell us to use a calculator. So...
y = 1.9
Therefore, the cube root of 7 is around 1.9. Hope this helps!
