So -390 -- 220 = -170

That was the change between the beginning and end of the turn.

PLEASE ANSWER WITH AN EXPLANATION! THANK YOU

Answer:

$\large\boxed{A=153\ cm^2}$

Step-by-step explanation:

<em>Look at the picture.</em>

We have

square with side length a = 9

trapezoid with base lengths b₁ = 9 and b₂ = 6 and the height length h = 6

right triangle with legs lengths l₁ = 3 + 6 = 9 and l₂ = 6

The formula of an area of a square

$A=a^2$

Substitute:

$A_I=9^2=81\ cm^2$

The formula of an area of a trapezoid:

$A=\dfrac{b_1+b_2}{2}\cdot h$

Substitute:

$A_{II}=\dfrac{9+6}{2}\cdot6=\dfrac{15}{2\!\!\!\!\diagup_1}\cdot6\!\!\!\!\diagup^3=(15)(3)=45\ cm^2$

The formula of an area of a right triangle:

$A=\dfrac{l_1l_2}{2}$

Substitute:

$A_{III}=\dfrac{(9)(6)}{2}=\dfrac{54}{2}=27\ cm^2$

The area of the shape:

$A=A_I+A_{II}+A_{III}\\\\A=81+45+27=153\ cm^2$

Answer:

See below

Step-by-step explanation:

<u>Given function:</u>

p(t)=3.1(1.016)^t

<u>The base of the growth rate is:</u>

1.016 = 1 + 0.016

It represent a 1.6% of growth per year.

A.

Increasing

B.

<u>p(55) = 7.42 means:</u>

55 years after 1963, in the year 2018, the population of Earth is 7.42 billions
