Question

The altitude of a plane as it begins to descend is shown by the linear equation

a = 30,000 – 1500m, where a is the plane’s altitude, in feet, and m is minutes.



What is the plane’s altitude when m = 12?

Answer 1

@STARSHIP

Answer 2

it should be 12000

Answer 3

12000? 100%?

Answer 4

I hate to doubt i just need to get this right

Answer 5

yeah if you plug in the number into the equation and use order of operations it should be correct

Answer 6

I can check the equation if you'd like

Answer 7

Ok thank you i only need help with 2 more would you mind staying?

Answer 8

And you don't have to do that

Answer 9

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 10

I got 304
I'll check it quickly

Answer 11

That's what i got

Answer 12

I just checked the equation and it's correct, 304 is the answer

Answer 13

Thank you and i think the second one i asked was 12300

Answer 14

I mean the one about the plane

Answer 15

THe answer was 12300?

Answer 16

Here is the final one

Answer 17

I'm sorry my bad

Answer 18

I checked and thats what i got

Answer 19

But you're all good here is the final one

Answer 20

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 21

Sigh i hate those ? marks

Answer 22

One sec lemme fix it

Answer 23

I'm sorry I'm not comfortable enough with linear and nonlinear modules to answer those

Answer 24

Aww

Answer 25

But it's cool thanks for the help!

Answer 26

I for some reason have no recoeaction of doing them

Answer 27

Oops typo, recollection
