Answer: 144 in^2

Step-by-step explanation:

The perimeter of a square can be calculated with the formula:

$P=4s$

Where s is the side lenght.

Solve for s:

$s=\frac{48in}{4}\\s=12in$

Use this value to calculate the area of the square with the following formula:

$A=s^2\\A=(12in)^2\\A=144in^2$

Answer:

area=144

Step-by-step explanation:

so we need to find the length of each side

since its a square there is 4 sides

perimeter is all the sides added up

48/4=12

the formula for a squares are is b*h

12*12= 144

The answer is $630.57

You first need to add both the borrowed money and the interest then divide it all by 30

$16,000+$2,917.10= $18917.10

$18917.10/30= $630.57

5. What is the equation of the tangent line to the circle x^2+y^2=1 through the point (6,0)?

notka56 [123]

Answer:

There is no tangent line of the given circle at (6, 0).

Step-by-step explanation:

Given equation of the circle,

$x^2 + y^2 = 1$

∵ equation of a circle is $(x-h)^2 +(y-k)^2 = r^2$ ,

Where, (h, k) is the center of the circle and r is the radius,

By comparing,

Center of the given circle = (0, 0),

Radius of the circle = 1 unit

Now, check whether point (6, 0) lie on the circle,

if x = 6, $6^2 + y^2 = 1$

$36 + y^2 = 1$

$y^2 = 1- 36$

$y= i\sqrt{35}\neq 0$

i.e., (6, 0) does not lie on the circle,

Hence, there is no tangent line of the given circle at (6, 0).

The area of a circle is 113.04 in.^2. What is the radius of the circle?

Lelechka [254]

$\bf \textit{area of a circle}\\\\
A=\pi r^2\qquad 
\begin{cases}
r=radius\\
------\\
A=113.04
\end{cases}\implies 113.04=\pi r^2
\\\\\\
\cfrac{113.04}{\pi }=r^2\implies \sqrt{\cfrac{113.04}{\pi }}=r$
