Answer:
Volume is dependent on how hard the air is pushed through. Sound travels more slowly than light. Sound waves travel at the same speed, but vibrate in different ways. Some vibrate quickly and have a high frequency or pitch, while others vibrate slowly and give a lower pitch.

Answer:
15
Step-by-step explanation:
Answer:
x=15
Step-by-step explanation:
Substutting in q(x) makes 3=4/5x-9
Add 9 to both sides to get 12=4/5x
Divide both sides by 4/5 and get 15=x
Thus, x=15

NEED HELP!! what are the coordinates of point j?
Answer:
(7,4)
Step-by-step explanation:
School guidelines require that there must be at least 2 chaperones for every 25 students going on a school trip. How many chaperones must there be for 82 students? A. 6 chaperones B. 41 chaperones C. 7chaperones D 3 chaperones
Answer:
A. 6 chaperones
Step-by-step explanation:
Since it's 2 chaperones per 25 students you would need to see how many times 25 can fit into 82
82/25 = 3.28
You can round that number to 3
Then you'll multiply 3 by 2 to get your number of chaperones for the school trip
3 x 2 = 6
There's still students left but not enough for there to be another chaperone so the answer is 6

If f(x) = 4x and g(x) = x^3, then what is f(g(x))?
a. 4x+x^3
b. 4x^4
c. 4x^3
d. (4x)^3
Answer:
f(g(x)) = 4x³
Hence, option C is true.
Step-by-step explanation:
Given
[tex]f(x) = 4x[/tex][tex]g\left(x\right)\:=\:x^3[/tex]Determine:
f(g(x)) = ?
solving the f(g(x))
f(g(x)) = f(x³)
= 4x³
Therefore,
f(g(x)) = 4x³
Hence, option C is true.

Find the slope of a line that passes through the points (2,3) and (4,1)
Answer:
The slope is -1
Step-by-step explanation:
Answer:
-1
Step-by-step explanation:
use y2-y1/x2-x1=m to find slope so if you plug both of the points in you would get 1-3/4-2=-2/2 and that would equal -1
What is the slope of this graph?
A. -1/4
B. 1/4
C. -4
D. 4
Answer:
-4
Step-by-step explanation:
its negative because it is decreasing from left to right and 4 because it goes down 4 over one not down one over four
Answer: B : -1/4
Step-by-step explanation: The line is going down to the right which is a negitive slope. So that takes out the options B and C. Then to find the slope you find a point and go over one down four, therefour -1/4. Hope This Helps!
The number line shows the locations of points A and C.
If point B is 1/3 of the way from point A to point C, what is the coordinate of point B ?
Answer:
Point B would be at 2.5

The distance traveled, in feet, of a ball dropped from a tall building is modeled by the equation d(t) = 16t2 where d equals the distance traveled at time t seconds and t equals the time in seconds. What does the average rate of change of d(t) from t = 2 to t = 5 represent?
The ball travels an average distance of 112 feet from 2 seconds to 5 seconds.
The ball falls down with an average speed of 48 feet per second from 2 seconds to 5 seconds.

How do solve this question? Find an equation of a line parallel to the given line and contains the given point. Write the equation in slope–intercept form. With the equation 2x + 5y= -10 point (10, 4).
Answer:
y = -2/5 x + 8Step-by-step explanation:
First we need to find the slope of the given line;
Given the line 2x + 5y= -10, we need to write it in standard form of y = mx+c
Make y the subject of the formula;
2x + 5y= -10
5y = -2x-10
y = -2x/5-10/5
y = -2x/5 - 2
Hence the slope of the line m = -2/5
Since the equation of the line we need is parallel to this line, hence they will have the same slope.
The slope of the required line = -2/5
Get the intercept;
Substitute the point (10,4) and m = -2/5 into the equation y = mx+c
4 = -2/5(10)+c
4 = -4 + c
c = 8
Get the required equation;
y = mx+c
y = -2/5 x + 8
Hence the equation of a line parallel to the given line and contains the given point is y = -2/5 x + 8

Natalie found a tennis ball outside a tennis court. She picked up the ball and threw it over the 12-foot fence into the court. The height of the ball, h, and time t seconds is given by the equations h(t) = -16t^2 + 18t +5. Will she make it iver the fence?
Answer:
Natalie cannot make it over the fence.
Step-by-step explanation:
After reading the statement, we must demostrate if the following inequation is possible, that is:
[tex]-16\cdot t^{2}+18\cdot t+5 \ge 12[/tex]
After some algebraic handling we find this equivalent expression:
[tex]16\cdot t^{2}-18\cdot t +7\le 0[/tex] (1)
The polynomial is factorized by the Quadratic Formula:
[tex]\left(t-0.563-i\,0.348)\cdot (t-0.563+i\,0.348)\le 0[/tex]
Since all roots are complex, we conclude that Natalie cannot make it over the fence.
