Answer:

891.75 sq.ft is the area of the polygon

Step-by-step explanation:

9.2^2 + 10^2= 184.64

√184.64= 13.59 feet

area of regular octagon=A=2(1+√ 2)a^2

A= 2(1+√2)13.59^2

A=891.75 sq.ft(approx)

Answer:

A)  2.1/6.3 = 8.7/X

Step-by-step explanation:

If two rectangles are similar, the ratio of the two shorter sides should equal the ratio of the two longer sides.

The two shorter sides are 2.1 cm and 6.3 cm

The two longer sides are 8.7 cm and X.

Therefore, as ratios:

2.1 : 6.3 = 8.7 : X

⇒ 2.1/6.3 = 8.7/X

Answer:

[tex]x\sqrt{2} = c[/tex]

Step-by-step explanation:

The Pythagorean theorem tells us that [tex]a^2+b^2=c^2[/tex], where a and b are the legs of a right triangle. If the length of each leg is x, we know by applying the theorem that [tex]x^2+x^2=c^2[/tex], so [tex]2x^2=c^2[/tex]. Applying the square root on both sides we get [tex]x\sqrt{2} = c[/tex]

Answer:

B. a rectangle

Step-by-step explanation:

A cross section is the new face you see when you slice through a 3D figure. So if you slice a rectangular pyramid parallel to the base, you get a smaller rectangle as the cross section. Similarly, if you slice parallel to a triangular base then your cross section will be a triangle.

Hope this helps and God bless!

Step-by-step explanation:

I think Its D because In the rectangular base its not equal sides like a square so it would be more be like sides that are not perpendicular.

Step-by-step explanation:

surface area of cylinder=2πr(r+h)

2*3.14*4(4+7)

25.12*11

276.3in²

Answer:

Step-by-step explanation:

2πrh+2πr^2 is the formula for finding the surface area of a cylinder.

Since the question said to use 3.14 for pi,

2 * 3.14 * 4* 7 + 2*3.14*16

= 175.84 + 100.48

= 276.32 in^2

So, the answer is d, 276.3 (rounded to 1 decimal place)

Answer:

Answer: k = - 20

Step-by-step explanation:

Solution

115 = -6k - 5              Add 5 to both sides

115+5 = - 6k - 5+5     Combine

120 = - 6k                   Divide by - 6

120/-6 = -6k/-6

-20 = k    

Answer: -20

Step-by-step explanation:115 = -6k-5

Add5 to both sides

120= -6k

Divide both sides by 6

20= -k

K = -20

Answer:

C

Step-by-step explanation:

The function has a variable that will make the graph curve up.

Answer:

B. y = -x – 1

Step-by-step explanation:

calculate slope  =

y2-y1   =  -5- (-2)  =  -3

x2-x1   =   4 - 1     =   3

m (slope) = -3/3 =  -1

using points (1,-2) for calculating y-intercept:

y = mx + b

-2 = -1(1) + b

-2 = -1 + b

-1 = b

b = -1

answer is B   y=  -x - 1

this a wierd question

Answer:

see images

Step-by-step explanation:

For all of these questions it helps to know the special right triangle, the 30°-60°-90° triangle. There is a special shortcut to find the sides of the 30°-60°-90° triangle.

For question4 and 5, these are equilateral triangles so the angles are all 60° So if you drop the height, it makes two 30°-60°-90° triangles. ***The short leg is HALF the hypotenuse or the hypotenuse is DOUBLE the short leg. The long leg is the short leg × sqroot3.***

This shortcut, special rt triangle info is used in all three of your questions. See image. Then you will have base and height or the apothem and side length for the Apothem Area formula:

A = 1/2 a•s•n

where a is the apothem, s is the side length and n is the number of sides. It looked like you already used this formula. See image.

Let's plug in a = 9 and b = 14

[tex]a^3 + b^3 = (a+b)(a^2 - ab + b^2)\\\\9^3 + 14^3 = (9+14)(9^2 - 9*14 + 14^2)\\\\9^3 + 14^3 = (9+14)(81 -126 + 196)\\\\9^3 + 14^3 = (23)(151)\\\\9^3 + 14^3 = 3473\\\\[/tex]

It is possible to calculate the terms on the right hand side without a calculator. You can either memorize things, do mental math, or use pencil/paper to do the scratch work.

As a way to verify things,

[tex]9^3 = 9*9*9 = 729\\\\14^3 = 14*14*14 = 2744\\\\9^3+14^3 = 729+2744 = 3473\\\\\text{Therefore, } 9^3 + 14^3 = 3473 \text{ has been proven correct}\\\\[/tex]

Answer:

3/4

Step-by-step explanation:

The approximate value of q in the equation below is 0.584

Given the log expression as shown below;

q + log2(6) = 2q + 2

Collect the like terms

q - 2q = 2 - log(2)6
-q = 2 - log(2)6

-q = log(2)4 - log(2)6

-q = 2 -2.584

-q = -0.584

q = 0.584

Hence the approximate value of q in the equation below is 0.584

Answers:

1: Option B: It is positve

2: Option B: -918 ÷ 34 = -27

3: Option B: False

( if the questions context is ONLY talking about dividing positives by a negative then its true, else if they are talking about ANY circumstance, even if negatives are divided by a negative then its false )

Step-by-step explanation:

For question 3:

When you divide a negative number by a positive number then the quotient is negative. When you divide a positive number by a negative number then the quotient is also negative. When you divide two negative numbers then the quotient is positive. The same rules hold true for multiplication.

Remarks

The answer given is pretty close to being correct. The 8 is correct -- that is 2^3 power.

The problem is in the minus sign. Think of it as (-1)^3

(-1)^3 = -1 * -1 * -1.

There are 3 minuses there. 2 of them will make plus 1. The third one will change the result to - 1.
