The world's population has grown at an average rate of 1.9 percent per year since 1945. There were approximately 4 billion peopl

kkurt [141]

Answer: $f(t) = 4000000000( 1 .019)^t$

Step-by-step explanation:

Here, According to the question, The population of the world is 4 billion (approx).

Again According to the question, The world's population has grown at an average rate of 1.9 percent per year since 1945.

Therefore, after 1975 the growth rate will remains same.

Thus, the population of the world after t years,

$f(t) = 4000000000( 1+\frac{1.9}{100} )^t$ (By the formula $A = P(1+\frac{r}{100})^t$ )

⇒ $f(t) = 4000000000( 1.019 )^t$

Where 1.019 is the growth rate and 4 billion is the initial population.

Vinil7 [7]

Answer:

626.7 $cm^{2}$

Step-by-step explanation:

Consider the figure as a circle with radius 7.5 and a rectangle with width 30 and length 15.

CIRCLE

A = pi*r*r = pi*7.5*7.5 = 56.25pi =176.7

RECTANGLE

A = l*w = 15*30 = 450

176.7 + 450 = 626.7 $cm^{2}$

Use the ray tool to graph f(x)=−|x−2| . (please include graph in answer.)

Fittoniya [83]

Answer:

The graph of $f(x)=-|x-2|$ is attached below.

Step-by-step explanation:

As the given function

$f(x)=-|x-2|$

Lets put some points to determine the graph.

For x = 0

$f(0)=-|0-2|=-2$

For x = 1

$f(1)=-|1-2|=-1$

For x = 2

$f(2)=-|2-2|=0$

For x = 3

$f(3)=-|3-2|=-1$

For x = 4

$f(4)=-|4-2|=-2$

Therefore, the graph of $f(x)=-|x-2|$ attached below.
