<span>Which shapes are topologically equivalent to Choice 2? D. NONE

Choice 1, 3, and 4 are topologically equivalent. These figures each have two holes.

Choice 2 has three holes and is different from the other.

Topologically equivalent figures are figures that can be rearranged to form another shape without breaking.</span>

A park is 4 times as it is wide. If the distance around the park is 12.5 kilometers what is the area of the park

MaRussiya [10]

Answer:

6.25 km

Step-by-step explanation:

Here is the correct question: A park is 4 times as long as it is wide. If the distance around the park is 12.5 kilometers, what is the area of the park?

Given: Perimeter (Distance) of the park= 12.5 km

Considering park is in rectangular shape.

Let the width of park be x

∴ as given length will be 4x.

Formula for perimeter of rectangle = $2\times (length + width)$

Perimeter is given 12.5 km

⇒ $12.5= 2\times (4x+x)$

⇒ $12.5= 10x$

∴ x= 1.25 km, which means width is 1.25 km and length is 5 km.

Now, finding the area of park

Formula; Area of rectangle= $length\times width$

∴ Area of rectangle= $5\times 1.25 = 6.25 km$

∴Area of park will be 6.25 km.

Plzzz help asapppppp what is the inverse of f if f(x)=^3 sqrt x-5

jasenka [17]

Hello from MrBillDoesMath!

Answer:

The first choice, y = x^3 + 5

Discussion:

Let

y = (x-5) ^ (1/3)

To find the inverse, sway x and y and then solve for y:

x = ( y - 5 )^(1/3) => cube both sides

x^3 = y - 5 => add 5 to both sides

x^3 + 5 = y

So the inverse is x^3 + 5, which is the first choice

Thank you,

MrB

ILL MARK AS BRAINLIST IF U GET IT RIGHT it’s khan

Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

given that x and y are proportional, they can be expressed as y = rx, where r is the proportionality constant. Thus, we can solve for r by doing y/x in any given point.

$\frac{8}{1.6} = \frac{15}{3} = \frac{22}{4.4} = 5$
