Elevators starts 90 feet below ground level after 15s it is 20 feet below ground level. So the distance it has gone up is 70 feet because 90-20=70. Use this common equation: speed =distance/time and put your values in to get the correct answer. Time is 15s. You can eliminate c and d before you even start as the elevator is moving upwards. For the questions below just use a calculator.

Describe a situation that models a linear pattern and then describe a situation that models a nonlinear pattern.
Nezavi [6.7K]
A linear pattern is when the points form a straight line. For example the following points follow a linear pattern: (0, 0), (1, 2), (2,4), (3,6). These points are all increasing by the same amount. X is increasing by 1 while Y increases by 2.
A non-linear pattern can pretty much be anything that doesn't follow an exact rule. Like: (0,1) (4,3), (6, 12), (7,9). These points would not form a straight line, it would just be a bunch of random points everywhere.

I hope that helps!

А support wire 12 yards long is attached to the top of a utility pole 10
stira [4]

Answer:

6.6 yd

Step-by-step explanation:

a^{2}+b^{2}=c^{2}

10^{2}+b^{2}=12^{2}        Substitute a= 10 and c=12

100+b^{2}=144      Evaluate the Powers

b^{2}=44               Subtract 100 on both sides.

b=\sqrt{44}             Square root both sides b>0 so you dont need ⊥

b=6.6              Use a calculator to evaluate.
