r-ruslan [8.4K]

Answer:

Building's actual height 32 meters

Building's shadow height 20 meters

Person's shadow height 1.2 meters

Person's actual height = ?

Find the person's actual height:

This is a proportion problem.

Actual height to shadow height

Building = Person

32 : 20 = x : 1.2

32 * 1.2 = 20 * x

38.4 = 20x

38.4/20 = 20x/20

1.92 = x

The person's actual height is 1.92 meters long.

32 : 20 = 1.92 : 1.2

32/20 = 1.60

1.92/1.2 = 1.60

AI = BI ➡ 3x+7 = 5x-11 ➡ 2x = 18 ➡ x = 9

replace x with 9

5x-11 ➡ 5×9-11 = 34

The range of the function f(k) = k2 + 2k + 1 is {25, 64}. What is the function’s domain?
s344n2d4d5 [400]
{k^2 + 2k + 1 = 25, k^2 + 2k + 1 = 64}
{k^2 + 2k - 24 = 0, k^2 + 2k - 63 = 0}
{(k - 4)(k + 6) = 0, (k - 7)(k + 9) = 0}
{k = -6, 4, -9, 7)
Therefore, range = {-9, -6, 4, 7)
