Answer:

Quadratic equation

Step-by-step explanation:

The formula is - b+- square root b^2 - 4ac all divided by 2a

a=1

b=-10

c=74

So substitute the values and remember to keep the value in a bracket so the outside operator affects it

-(-10)+- square root (-10)^2 - 4(1)(74) all divided by 2(1)

ki77a [65]

You're given the value of m so you plug that in the equation given to get 1500=-475t+2650. Now with some algebra just solve it for t! so subtract 2650 and get -1150=-475t. Now divide by -475 and get 2.4. Now the t value is already in hours, so there's no conversions, and the closest answer is A! This makes sense because it's an approximation :)
