A temperature probe registers a temperature of -124° C. If the probe's temperature increases
by 8 °C per hour, after how many hours will it
be at a temperature of 4°C?

16 hours

Step-by-step explanation:

Given

per hour

Required

Determine the number of hours it gets to 4 degrees

Let the temperature at every hour, h be T.

So, we have:

To calculate the time it gets to 4 degrees. We first substitute 4 for T; then solve for h

Solve for h

1/5x+9 2/5y+7

step-by-step explanation:

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
