Answer:

[tex]Height = 8.660\ in[/tex]

[tex]Width = 17.321\ in[/tex]

Step-by-step explanation:

Given

[tex]Area= 150in^2[/tex]

[tex]Side\ Margin = 1\ in[/tex]

[tex]Top\ \&\ Bottom\ Margins = 2\ in[/tex]

Required

Determine the smallest dimension to use

To answer this question, I'll make use of the attached figure as a point of reference.

The area of the printed matter is:

[tex]Area = Length * Width[/tex]

[tex]A_1 = H * W[/tex]

Substitute 150 for A1

[tex]150 = H * W[/tex]

Make H the subject

[tex]H = \frac{150}{W}[/tex]

The area of the full paper is:

[tex]Area = Length * Width[/tex]

[tex]A_2 = (W + 2+2) * (H + 1 + 1)[/tex]

[tex]A_2 = (W + 4) * (H + 2)[/tex]

Substitute 150/W for H

[tex]A_2 = (W + 4) * (\frac{150}{W} + 2)[/tex]

Open brackets

[tex]A_2 = W(\frac{150}{W} + 2) + 4(\frac{150}{W} + 2)[/tex]

[tex]A_2 = 150 + 2W + \frac{600}{W} + 8[/tex]

Collect Like Terms

[tex]A_2 =2W + \frac{600}{W} + 8+150[/tex]

[tex]A_2 =2W + \frac{600}{W} + 158[/tex]

Differentiate with respect to w and set the result to 0

[tex]A_2' = 2 - \frac{600}{W^2} + 0[/tex]

[tex]A_2' = 2 - \frac{600}{W^2}[/tex]

Set to 0

[tex]0 = 2 - \frac{600}{W^2}[/tex]

Collect Like Terms

[tex]2 = \frac{600}{W^2}[/tex]

Cross Multiply

[tex]2 * W^2 = 600[/tex]

Make [tex]W^2[/tex] the subject

[tex]W^2 = \frac{600}{2}[/tex]

[tex]W^2 = 300[/tex]

Take positive square root of both sides

[tex]W = 17.321[/tex]

Recall that:

[tex]H = \frac{150}{W}[/tex]

[tex]H = \frac{150}{17.321}[/tex]

[tex]H = 8.660[/tex]

Hence, the smallest dimension of the paper is:

[tex]Height = 8.660\ in[/tex]

[tex]Width = 17.321\ in[/tex]

Answer:

H=18

W=12

Step-by-step explanation:

The question says 1 inch margins on the sides AND the top. And THEN a 2 inch margin ONLY on the bottom.

First, solve for y,

A = xy

150 = xy

150/x = y

If the center dimensions is A and its it equals x*y, then plus the margins, the outer dimensions would just be x+(size of margins) for width and y+(size of margins) for height.

This gives us

Width: x + 2

Height: y + 3  

Putting height into terms of x: (Substitute y) = 3 + 150/x

Now, since the area of a rectangle is b*h, the equation is:

(x + 2)(3 + 150/x)

Simplify:

3x + 150 + 6 + 300/x

= 3x + 156 + 300/x

Next, we find the derivative of this and then solve for x.

= 3 - 300/x^2

Solving for x:

0 = 3 - 300/x^2

3 = 300/x^2

3x^2 = 300

x^2 = 100

x = 10

Now that we have x, we plug this into the different equations for height and base:

Base=(10) + 2 = 12

Height=3 + 150/(10) =3+15 = 18

Hope this helps!

Answer: x=7

Step-by-step explanation:

Step 1: Subtract 17x from both sides.

13x+15−17x=17x−13−17x

−4x+15=−13

Step 2: Subtract 15 from both sides.

−4x+15−15=−13−15

−4x=−28

Step 3: Divide both sides by -4.

−4x/−4 =−28/−4

x=7

Answer:

There's a very simple way to solve this kind of problem. All we have to do is change the percent to a decimal and multiply it by her current grade.

81 × .15 = 12.15

For our purposes, we'll just round it down to 12. But anyway, raising her grade by 15% would mean raising it by 12 points.

81 + 12 = 93

This would give her an average of 93, not 95. She'd need to raise her grade 18% from 81 to get to her goal.

Answer:

3√512 = 8

Step-by-step explanation:

Step 1: Find the prime factors of 512

512 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2

Step 2: Pair the factors of 512 in a group of three, such that they form cubes.

512 = (2 × 2 × 2) × (2 × 2 × 2) × (2 × 2 × 2)

512 = 23 × 23 × 23

Using the law of exponent, we get;

512 = 29 [am.an = (a)m+n]

Or

512 = (23)3 [(am)n = amn]

512 = 83

Step 3: Now, we will apply cube root on both the sides to take out the factor (in cubes) as a single term.

3√512 = 3√(83)

So, here the cube root is eliminated by the cube of 8.

Hence, 3√512 = 8

Answer:

y = - 3x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 3, then

y = - 3x + c ← is the partial equation

To find c substitute (3, - 2) into the partial equation

- 2 = - 9 + c ⇒ c = - 2 + 9 = 7

y = - 3x + 7 ← equation of line
