A computer repair shop charges a flat rate of $50 plus $35 per hour spent repairing each computer. Let H be the number of hours spent repairing a computer, use function notation to write an equation that gives the total charges for repairing a computer as a function of h. Graph the function.

f(h) = 50 + 35h

Step-by-step explanation:

Let h = number of hours spent repairing a computer

if a computer repair shop charges a flat rate of $50 plus $35 per hour spent repairing each computer, then:

f(h) = 50 + 35h

graphing the function:

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
