Pam ordered a circular hot tub cover with a diameter of 80 inches. Find the area of the hot tub cover.

Nataliya [291]

Answer:

5026.55in²

Step-by-step explanation:

Area = πr^2

radius (r) is half of the diameter, hence the radius is 40 inches

So after plugging that in, the equation should look like

Area = π(40)^2

A = 1600π ≈ 5026.55

The units for this is in² so just add that in the end

Using SET NOTATION, what is the solution set for the following equation? a² - 3 = 22

UNO [17]

The solution set is $\{-5,5\}$

Explanation:

The given equation is $a^{2}-3=22$

To determine the solution set of the equation, let us solve the equation.

Adding both sides of the equation by 3, we have,

$a^2=25$

Taking square root on both sides of the equation, we get,

$a=\sqrt{25}, a=-\sqrt{25}$

$a=5, a=-5$

Thus, the solution of the equation is $a=5, a=-5$

The solution set of the equation is the set which contains all the solutions of the equations.

Thus, writing the solutions of the equation using set notation, we have,

$\{-5,5\}$

Thus, the solution set is $\{-5,5\}$

Diego plans to build an extension to his rectangular model bridge. Let x represent the increase, in centimeters, of the model's

marishachu [46]

Answer:

(21x+168)cm²

Step-by-step explanation:

If the expression 2 1 (x + 8) represents the area of the model bridge, where 2 1 is the width, in centimeters, and (x + 8) represents the extended length, the expression that is equivalent to 21(x+8) can be gotten by expanding the function. The expansion of the function will give the area of the rectangular model bridge as shown;

21(x+8) = 21x+ 168

The expression equivalent to 21(x+8) is therefore (21x+68)cm²

Note that the the unit of the value and function given is in cm therefore the unit of their equivalent expression will be in cm²
