Answer:

2 square units

Step-by-step explanation:

hello

The scale factor or linear scale factor is the ratio between the length of the same side in two similar figures.

in the graph we have a rectangle with width 5 units and long 10 units, and we know the scale factor is 1/5

$S_{f}=\frac{width(C)}{width(B)}\\ \\Width(B)*S_{f} =width(C)=5 units *\frac{1}{5} \\\\Width(C) =\frac{5}{5} units =1 unit$

$S_{f} =\frac{length (C)}{length(B)} \\\\\\length(C)=length(B)*S_{f}\\length(C)=(10*\frac{1}{5})$

$Length(C) =2 units\\\\ the area is A=w*l\\\\A=1 unit * 2 units\\\\\\$

A=2 square units

I hope it helps

Answer:

The area of rectangle C is 2

Step-by-step explanation:

Using a scale factor of $\frac{1}{5}$ yields the side lengths of 1 and 2

$(1)(2)=2$

Answer:

P=1620

Third option

Step-by-step explanation:

Horizontal Asymptotes

A given function is said to have a horizontal asymptote in y=a, if:

$\displaystyle \lim _{x\rightarrow -\infty }f(x)=a$

Or,

$\displaystyle \lim _{x\rightarrow +\infty }f(x)=a$

For the given function, the population of the species of bird is given by :

$\displaystyle p(t)=\frac{1620}{1+1.15e^{-0.042t}}$

Where t is the time in years. To find the horizontal asymptote, we should compute both limits to check if they exist.

$\displaystyle \lim _{x\rightarrow +\infty }\frac{1620}{1+1.15e^{-0.042t}}=\frac{1620}{1+0}=1620$

When t tends to plus infinity, P tends to 1620 .

The second asymptote is computed by:

$\displaystyle \lim _{x\rightarrow -\infty }\frac{1620}{1+1.15e^{-0.042t}}=\frac{1620}{1+\infty}=0$

When t tends to minus infinity, P tends to zero. Since the domain of P is $t\geq 0$ , this asymptote is not valid, thus our only asymptote is

$\boxed{P=1620}$

A car is traveling at a rate of 120 kilometers per hour. What is the cars rate in miles per hour? How many miles will the car tr

Ymorist [56]

Answer:

150 miles

Step-by-step explanation:

speed = 120 km per hour

1 mile = 1.6 km

speed = 120 km per hr

divide 120 with 1.6 to get in miles=120/1.6

= 75 miles per hour

speed = 75 miles per hour

So, in 1 hr, it can travel 75 miles

the distance traveled by car in 2 hours = 75 * 2 = 150

Result : Speed = 75 miles per hour , distance = 150 miles

What is the radius of the Brazilian coin that has a circumference of 84.78 mm? Explain your work. Use 3.14 pi

ICE Princess25 [194]

Hey there!

Sorry If this answer is late, but here ya go.

To find the radius of this Brazilian coin, first multiply 3.14 by 2. This will give you and answer of 6.28. Then, divide 84.78 mm by this, and you will get your radius of 13.5.

Have a good day! And stay CRAZZZY! :D
