Write a linear function f with f(4)=−3 and f(0)=−2.
Answers
Answer:
f(x)=-1/4x-2
Step-by-step explanation:
m=-3-(-2)/4-0=-1/4= slope
b=y-intercept=-2,
so f(x)=-1/4x-2
A linear function f with f(4)=−3 and f(0)=−2 is
[tex]f(x)=-\frac{1}{4}x-2[/tex]
Given :
a linear function f with f(4)=−3 and f(0)=−2.
f(0)=-2. It means y intercept is -2
Linear equation of a line is given by y=mx+b
where m is the slope and b is the y intercept
y intercept b is -2
Lets find out slope m . Lets use f(4)=-3 that is when x=4 the value of y is -3
[tex]y=mx+b\\y=mx-2\\x=4, y=-3\\-3=m(4)-2\\-3+2=4m\\-1=4m\\m=-\frac{1}{4}[/tex]
Now we replace in the equation of line y=mx+b
[tex]y=mx+b\\y=-\frac{1}{4}x-2[/tex]
Replace y with f(x) to get linear function
[tex]f(x)=-\frac{1}{4}x-2[/tex]

Zach lives in Salina, Kansas. Gina lives 45 miles east in Junction City, Kansas. Gina and Zach both leave their houses at the same time, heading east on I-70. Zach drives 65 miles per hour and Gina drives 55 miles per hour. Zach wants to determine how long it will take before he catches up with Gina.
Answers
Answer:
4.5 hours
Step-by-step explanation:
Given that Gian lives 45 miles east of Salina where Zach lives.
At the same time, both start driving in the same direction towards the east, Zach drives 65 miles per hour and Gina drives 55 miles per hour.
Let A and B are the initial locations of Zach and Gina respectively, after t hours they meet at point C which x miles east of point B as shown in the figure.
Distance traveled by Gina = BC= x miles
As distance = speed x time, so
[tex]x= 55 \times t \cdots(i)[/tex]
Similarly, distance traveled by Gina = AC= (45+x) miles
As distance = speed x time, so
[tex]45+x= 65 \times t \\\\[/tex]
[tex]\Rightarrow 45+55t= 65 \times t[/tex] [ using equation (i)]
[tex]\Rightarrow 10t= 45 \\\\[/tex]
[tex]\Rightarrow t = 45/10 = 4.5[/tex] hour
Hence, the required time is 4.5 hours.

What is the angle of depression from the start of a 6-foot high access ramp that ends at a point 40 feet away along the ground? Nearest tenth of a degree.
Answers
Answer:
8.5 degreesStep-by-step explanation:
The set up will give a right angles triangle;
Given
The height of the ramp (opposite) = 6 foot
distance away along the ground = 40 feet (adjacent)
Required
Angle of depression theta
Using the TOA identity;
tan theta = opposite/adjacent
tan theta = 6/40
tan theta = 0.15
theta = tan^-1{0.15}
theta =8.53 degrees
hence the angle of depression to nearest tenth of a degree is 89.5 degrees

The histogram shows the heights in meters of trees in a certain section of a park. How many trees are less than 20 meters tall? A. 16, B. 9, C. 4, or D. 15
Answers
Answer:
The histogram shows the heights in meters of trees in a certain section of a park.
How many trees are less than 20 meters tall?
Answer: From the given histogram, we clearly see:
There is 1 tree with height less than 8 meters
There are 1 + 2 = 3 trees with height less than 12 meters
There are 3 + 2 = 5 trees with height less than 16 meters
There are 5 + 4 =9 trees with height less than 20 meters.
Therefore, the correct option is B. 9

Step-by-step explanation:
It is given that,
The average distance between the Earth and the Moon is 384 400 km.
We need to express in in standard form.
1 km = 1000 m
It means,
384400 km = 384400000 km
or
= [tex]3.84\times10^8\ m[/tex]
Hence, the average distance between the Earth and the Moon is [tex]3.84\times10^8\ m[/tex].

If 30/t = 18/r, then t/r =
Answers
Answer:

t = 5/3r
--------------------
30/t = 18/r
30r = 18t/r

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using the equation, find out the time at which the rocket will reach its max, to the nearest 100th of a second y=-16x^2+235x+133
Answers
Answer:
Step-by-step explanation:
Given tq equation of the height reached by the rocket as y=-16x^2+235x+133
The velocity of the object at its maximum height is zero
v = dy/dx = 0(at max height)
v =-32x +235
0 =-32x+235
x = 235/32
x = 7.34
Hence the rocket will reach its maximum height after 7.34seconds

Step-by-step explanation:
So if we add 20 and 10 we get 30 which is the total amount of games played. We know that the team won 20 of the 30 games which we can reduce to 2/3. 2/3 is equal to 66.66 but most people just say 66% or you can round it up to 67%

The value 5 is an upper bound for the zeros of the function shown below.
f(x)= x4 + x3 – 11.x2 – 9x + 18
A. True
B. False
Answers
Answer:
The given statement that value 5 is an upper bound for the zeros of the function f(x) = x⁴ + x³ - 11x² - 9x + 18 will be true.
Step-by-step explanation:
Given
[tex]f\left(x\right)\:=\:x^2\:+\:x^3\:-\:11x^2\:-\:9x\:+\:18[/tex]
We know the rational zeros theorem such as:
if [tex]x=c[/tex] is a zero of the function [tex]f(x)[/tex],
then [tex]f(c) = 0[/tex].
As the [tex]f\left(x\right)\:=\:x^2\:+\:x^3\:-\:11x^2\:-\:9x\:+\:18[/tex] is a polynomial of degree [tex]4[/tex], hence it can not have more than [tex]4[/tex] real zeros.
Let us put certain values in the function,
[tex]f(5) = 448[/tex], [tex]f(4) = 126[/tex], [tex]f(3) = 0[/tex], [tex]f(2) = -20[/tex],
[tex]f(1) = 0[/tex], [tex]f(0) = 18[/tex], [tex]f(-1) = 16[/tex], [tex]f(-2) = 0[/tex], [tex]f(-3) = 0[/tex]
From the above calculation results, we determined that [tex]4[/tex] zeros as
[tex]x = -3, -2, 1,[/tex] and [tex]3[/tex].
Hence, we can check that
[tex]f(x) = (x+3)(x+2)(x-1)(x-3)[/tex]
Observe that,
[tex]for x > 3[/tex], [tex]f(x)[/tex] increases rapidly, so there will be no zeros for [tex]x>3[/tex].
Therefore, the given statement that value 5 is an upper bound for the zeros of the function f(x) = x⁴ + x³ - 11x² - 9x + 18 will be true.
