Answer: 38 meter per second
Step-by-step explanation:
Given: The variable d models Rachel's distance from her exit (in meters) t seconds after the cameras began recording the stunt.
where -38 is the rate of change of function .
Since speed is the rate of change of position with respect to time , thus
Speed =-38 meter per second which shows decrease in distance with respect to time.
At t=0 second, d=220 meters
At t=1 second , 
meters
Distance traveled in 1 second = 220-182=38
Now, Rachel's speed=
Rachel's speed=
=38 meter per second
I believe the answer is A because you cannot find x nor y
Answer:
x = 10, y ≈ 11.2
Step-by-step explanation:
Hi there,
We can find the length x first since we are given the lengths of the other two sides of the bottom right triangle. In order to find the length of x, it is important to know the Pythagorean Theorem and the fact that x is the hypotenuse.
+ 
= 
← Pythagorean Theorem
<u>To find x:</u>
+ 
=
100 =
c = 10
Therefore, the value of x is 10.
<u>To find y:</u>
We now know the length of two sides of the upper right triangle. The value of y can be found by using the theorem again.
+ 
= 
+ 100 = 225
= 125
a = 
a = 11.2 when rounded to the nearest tenth.
Therefore, the value of y is approximately 11.2.
Hope this explanation is useful. Cheers.
sorry i cant solve this problem
maybe next time
hope you understand me!
Answer:
There is no graph but I can infer that if time is on the x axis it would be C and if distance is on the x axis it would be B
