There are 50 tree frogs in the botanical gardens at t = 0. The population increases exponentially by 20% per year.
Elodia [21]

Answer:

A)

f(t) = 50 * 1.2^t

B)

f(3) = 50 * 1.2^3 = 86.4 tree frogs

C)

f(t) = 50 * 1.2^t = 200 --> t = LN(200/50)/LN(1.2) = 7.604 years

D)

f(-1) = 50 * 1.2^(-1) = 41.67 tree frogs

Multiple choice <br> a. 12 pie cm <br> b. 21 pie cm <br> c. 35 pie cm
Karolina [17]

Answer:

The correct option is;

a. 12 pie cm

Step-by-step explanation:

Cavalieri's principle states that if the cross-sectional area of two or more figures of the same altitude are the same at each level of the figures, then the volumes of the figures are also the same;

Given that the base area of the square based prism and the cylinder are the same, and that the square based prism and the cylinder have equal height of 4 cm, then by Cavalieri's principle, their volumes are the same

The volume of the square based prism = 452 cm³

Therefore, the volume of the cylinder (of equal base area) = 452 cm³

The formula for the volume of square based prism = Area of base × Height

∴ The volume of square based prism, 452 cm³ = Area of base × 4 cm

Which gives;

Area of the base of the square based prism  = 452/4 = 113 cm²

The area of the base of the cylinder A_c  = The area of the base of the square based prism = 113 cm²

The area of the base of the cylinder,A_c  is given by the following equation;

A_c = π×r² = 113 cm²

r = √(113/π) = √35.97 ≈ √36  = 6 cm

The circumference of the base of the cylinder,C_c  is given by the following equation

C_c = 2×π×r ≈ 2×π×6 = 12×π cm

The correct option is 12 pie cm.

identify an equation in point slope form for the line perpendicular to y=-2x+8 that passes through (-3,9)
Svetach [21]

Answer:

y - 9 = 1/2(x + 3)

Step-by-step explanation:

find the slope that is perpendicular to line y = -2x + 8, which is the negative reciprocal slope: 1/2

substitute the new slope 1/2 and the given/known point (-3, 9) into the point-slope form:

=> y - 9 = 1/2(x - (-3)) => y - 9 = 1/2(x + 3)

point-slope form:
