Find the area of a trapezoid , given the bases b1 = 14 mi and b2 = 25 mi and hight h= 6 mi

elena55 [62]

Answer:

area = 117

Step-by-step explanation:

The area (A) of a trapezoid is calculated using the formula

A = $\frac{1}{2}$ h (b₁ + b₂ )

here h = 6, b₁ = 14 and b₂ = 25

A = $\frac{1}{2}$ × 6 × (14 + 25) = 3 × 39 = 117

The population of a suburb is 4000 people. The population of the suburb

Lisa [10]

Answer:

1000

Step-by-step explanation:

The population of the suburb after each decade d is given by the equation as follows :

$P=4000\times 2^d$

We need to evaluate the expression for d = -2.

Put d = -2 in the above equation. So,

$P=4000\times 2^{-2}\\\\=4000\times \dfrac{1}{2^2}\\\\=4000\times \dfrac{1}{4}\\\\=1000$

So, if d = -2, then the population of the suburb is equal to 1000.
