I agree with ur answer...
d = 16t^2....divide both sides by 16
d / 16 = t^2 ...take the square root of both sides, eliminating the ^2
sqrt (d/16) = t
(sqrt d) / 4 = t
Answer:
5
Step-by-step explanation:
5²=25 and 6²=36
25 is way closer to 27 than 36
so
5
Answer:
The answer is 234
Step-by-step explanation:
Part A: In (0,4) and (1,8), as x increases from 0 to 1, y increases from 4 to 8. The slope of the line connecting these 2 pts. is (8-4) / (1-0), or 4. Now do the same thing for the 2 pts (1,8) and (2, 10). You will find that the slope in the 2nd case is different. Thus, the 3 given pts do NOT lie on a straight line. Function is non-linear.
Part B: an example of a non-linear function would be y = 2x^2 - 5. You can tell immediately from that exponent, 2, that this function is non linear.
An ex. of a linear function would include x to the 1st power only: y = 3x - 7.
Lydia washes 1/2 car in 1 hour. Jackie washes 1/1 car in 1 hour.
1/2 + 1/1 = 1/2 + 2/2 = 3/2
They both washes 3/2 cars in 1 hour and so they washes the car in 2/3 of an hour. 2/3 hour = 40 minutes
