If f(x) = 7 (x-1) + 8 , what is the value of f (1)

f(1) = 8

Step-by-step explanation:

Step 1: Define

f(x) = 7(x - 1) + 8

f(1) = x = 1

Step 2: Substitute and evaluate

f(1) = 7(1 - 1) + 8

f(1) = 7(0) + 8

f(1) = 8

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

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%
