Complete Question:
An object dropped from rest from the top of a tall building on Planet X falls a distance d(t)=13t^2 feet in the first t seconds. Find the average rate of change of distance with respect to time as t changes from t1=2 to t2=10. This rate is known as the average velocity, or speed.
The average velocity as t changes from 2 to 10 seconds is _______ feet/sec?
Answer:
Step-by-step explanation:
Given
Time Interval: (a,b)
Required
Determine the average rate of change (v)
This is calculated as thus:
Substitute values for b and a
Calculate d(10): Substitute 10 for t
Calculate d(2): Substitute 2 for t
The equation becomes
Hence, the average rate of change is 156ft/s

Answer:
2x + y -6 = 0
Step-by-step explanation:
The general form is 
. It requires that A and B be greater than 1 (not fractions or decimals) and A is positive. This equation is 2x + y = 6 is almost already in the form. Subtract C to both sides to make it general form. 2x + y - 6 =0. The coefficients of the x and y are greater than 1 and 2 is positive. This meets the requirements.
Answer:
B. x = 20
Step-by-step explanation:
angles on a straight line are supplementary
therefore, 6x+9 + 2x+11 = 180
so, 8x+20=180
8x = 160
x = 20
Hello from MrBillDoesMath!
Answer:
r = = 57.6 (approximately)
Discussion:
Given: circumference of circle O = 362.14
The circumference of a circle of radius r, is given by the formula C = 2 *PI *2.
So we need to find the value of r in
2*Pi*r = 362.14
Divide both sides by 2*PI to get
r = (362.14)/ (2 * Pi) = (362.14)/ 6.283 (approximately)
= 57.6 (approximately)
Thank you,
