Question

can someone help me with two quick questions please?! I will fan and medal!

Answer 1

What are the questions?

Answer 2

The amount of money a plumber charges when visiting a home to make a repair is shown by the linear equation c = 135 + 52h, where c is the amount the plumber charges and h is the number of hours spent at the home.

How much does the plumber charge when h = 3.25?

Answer 3

I think its 12,300

Answer 4

@AloneS

Answer 5

c = 135 + 52h
h = 3.25

So what we need to do here is substitute in the value of our variable:
c = 135 + 52(3.25)

Then simply solve:
c = 135 + 169
c = 304

Answer 6

oh XD thanks, I have one more

(1 pt)
Is each situation a linear or a nonlinear model?
Column A Column B
1.
The height of a ball when it is thrown into the air is shown by equation h = −16t2 + 20t + 3, where h is the height of the ball and t is time in seconds since the ball was released.
2.
A salesperson’s monthly earnings are shown by the equation e = 1200 + 0.04s, where e represents the salesperson’s monthly earnings and s is her monthly sales.
3.
The amount of a 500 g sample of a radioactive substance that remains over time is given by the equation , where d is the number of days since the sample weight was 500 g.
4.
Mikaela’s distance from home as she drives at a constant rate is given by the equation d = 368 – 42t, where d is her distance from home and t is time in hours.

Answer 9

The height of a ball when it is thrown into the air is shown by equation h = −16t2 + 20t + 3, where h is the height of the ball and t is time in seconds since the ball was released.
A.
linear model
B.
nonlinear model

Answer 10

I'm afraid I can't help you here... try looking up definitions of linear and nonlinear model

Answer 11

I can break the question up for you, I just relised how hard it looks XD

Answer 12

@AmTnRider can you help me buddy? XD

Answer 13

The height of a ball when it is thrown into the air is shown by equation h = −16t2 + 20t + 3, where h is the height of the ball and t is time in seconds since the ball was released.
A.
linear model
B.
nonlinear model

Answer 14

anyone thats looking at this, please ignore the top questions XD

Answer 15

this is the question I need help on
The height of a ball when it is thrown into the air is shown by equation h = −16t2 + 20t + 3, where h is the height of the ball and t is time in seconds since the ball was released.
A.
linear model
B.
nonlinear model

Answer 16

About the ball is nonlinear

Answer 17

Salesperson is linear. Mikaela's distance is linear.

Answer 18

About radioactive substance i don't understand. If the equation has power over or below 1 then it is nonlinear equation

Answer 19

thanks :D
