$y= \frac{1}{4}x-6 \\ \\x=-8 \Rightarrow y=\frac{1}{4}* (-8)-6=-2-6=-8\\ \\x=-4 \Rightarrow y=\frac{1}{4}* (-4)-6=-1-6=-7\\ \\x=0 \Rightarrow y=\frac{1}{4}* 0-6=0-6=-6\\ \\x=4 \Rightarrow y=\frac{1}{4}*4-6=1-6=-5 \\ \\x=8 \Rightarrow y=\frac{1}{4}*8-6= 2-6=-4$

Jimmy paid off a mortgage by paying $775 per month for 12 years. What was the original amount of the mortgage if the interest ra

valentinak56 [21]

Answer:

The original amount of the mortgage was $66231.45.

Step-by-step explanation:

In order to find the original amount of the mortgage, you can use the following formula to calculate the present value:

PV=FV/(1+r/n)^nt

PV=present value

FV=future value= 775*12*12=111.600

r=rate of interest=0.0440

n= number of compounding periods= 2

t= time in years=12

Now, you can replace the values on the formula:

PV=111600/(1+(0.0440/2))^2*12

PV=111600/(1.022)^24

PV=111600/1.685

PV=66231.45

According to this, the answer is that the original amount of the mortgage was $66231.45.

Alecia builds a box in the shape of a cube with an open top. She plans to paint the box. Alecia calculates that there are 256 sq

STALIN [3.7K]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the options to select the required condition from were not listed. So, I will answer on general terms

From the question, we understand that the cube has an open-top and the surface ares is 256 in^2

Let L represents the edge length, the surface area (S) is:

$S = 5L^2$

Substitute 256 for S

$256 = 5L^2$

Divide both sides by 5

$51.2 = L^2$

Take square roots of both sides:

$\sqrt{51.2} = L$

$7.155= L$

$L=7.16in$ ---- approximated

The volume of the cube is:

$Volume = L^3$

$Volume = \sqrt{51.2}^3$

$Volume = 366.3573$

$Volume = 366.36in^3$

<em>So, the edge length of the cube is 7.16 inches and the volume is 366.36 cubic inches</em>
