Please I really need help on these two
oksian1 [2.3K]

Answer:

1) 5

2) (3 , 24)

Step-by-step explanation:

Question 1

f(x) x= 1    2 * 5¹ = 10

f(x) x= 2    2 * 5² = 50

f(x) x= 3    2 * 5³ = 250

multiplicative rate of change = 50/10 = 5

check: 250/50 = 5

Question 2

f(x) = 2 * 4ˣ

(3 , 24)     f(3) = 2 * 4³ = 2 * 64 = 128 ≠ 24

Cone

Givens

r = 1.5 inches

h = 4 inches

Formula

V = 1/3 pi r^2 h

V = 1/3* 3.14 * 2.25 * 4

V = 9.42

Semi sphere

V = 7.065

Total

V = 9.42 + 7.065

V = 16.485

Rounded to the nearest 1/100

V = 16.49
