Answer:
22969.39 yd^2
Step-by-step explanation:
Alright to start, lets do the easier part of it, the sides of it. Since it is an octagonal prism, there are 8 rectangular sides to it. Each of these sides can be found with L*W, so use the given length of 15 and width of 6 to do this.
15 * 6 = 90
Since there's 8 of these:
90 * 8 = 720
Now, with the tricky part with the bases of the octagonal prism. Let's find the perimeter of the octagon, so use the top width of each of the rectangles.
6 * 8 = 48 = Perimeter
Now, here's the magic equation to avoid making this more complicated:
2(1+√2)p^2
Then plug in p
2(1+√2)48^2
(2+2√2) * 2304
(2+2.8284)*2304
4.8284*2304
11124.69...
But there's two bases so: 22249.39
Lastly, add this to the 720 from the rectangular prisms.
22249.39+720 = 22969.39
Hope that helps.
change from quadratic to vertex form.
Answer:
Factor out 1/3 because its a coefficient of x².
Why?
In order to proceed and complete the square... We need the coefficient of x² to be 1 and luckily for us.... Factoring 1/3 even makes everything easier
y=1/3[ x² + 20x + 97]
Using completing square on the function inside the bracket
x² + 20x + 10² + 97 – 10²
We have it to be( x + 10)² - 3]
y = 1/3[ (x +10)² - 3]
This is our Vertex Form... y=1/3[(x + 10)² - 3]

A quadratic function y=f(x) is plotted on a graph and the vertex of the resulting parabola is (−5,−3). What is the vertex of the function defined as g(x)=−f(x)+3?
Answer:
(-5 , 6)
Step-by-step explanation:
f(x) = (x - (-5))² - 3 ... vertex (h , k) : (-5 , -3) y = (x-h)² + k
g(x) = -f(x) + 3 = -((x+5)² - 3) + 3 = -(x + 5)² + 6
vertex of g(x) is : (-5 , 6)

Complete the square to write each equation in vertex form. Then, state whether the vertex is a minimum or a maximum and give its coordinates.
Answer:
see explanation
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
• If a > 0 then vertex is minimum
• If a < 0 then vertex is maximum
Given
y = x² + 6x + 10
(a)
To complete the square
add/subtract ( half the coefficient of the x- term)² to x² + 6x
y = x² + 2(3)x + 9 - 9 + 10
y = (x + 3)² + 1 ← in vertex form
(b)
Since a = 1 > 0 then vertex is a minimum
(c)
(h, k ) = (- 3, 1 ) ← coordinates of vertex

What is the y-intercept of the line that goes through the points (5, -8) and (9, -12)
Answer:
-3
Step-by-step explanation:
Given the points, we can see that as x increases by 4, y decreases by 4, which means the slope is -1. Working backwards from (5, -8), we can decrease x by 5 (and thus increase y by 5, since we're subtracting a negative) and add that to -8 to find the y-intercept = -3

Elizabeth buys 50 meters of ribbon to make bows for the cheer squad. Each bow uses 1.3 meters of ribbon. How many bows can Elizabeth make? *
Answer:
38 bows
Step-by-step explanation:
50 ÷ 1.3 ≡ 38 6/13
38 × 1.3 = 49.4
Since you cant make 6/13 of a ribbon, Elizabeth would be able to make 38 bows.
does leave as the whole percentage mean if it was 5.4% you would have it as 5%
Answer:
It is about rounding.
You would round up or down depending on the number after decimal.
If it is < 5 you drop it, if equal or greater than 5 then round up to the next whole number.
5.4% is rounded down to 5% since 4 < 5.

HELP DUE IN 10 MINS!
Determine which of the following quadrilaterals have the property below. Choose all that apply.
Diagonals are congruent??
Parallelogram
Rhombus
Rectangle
Square
Kite
Isosceles Trapezoid
Answer:
Step-by-step explanation:
Of that list, only the square and the rectangle have the property you are asking for.
Try drawing it. The parallelogram has a shorter diagonal from the two obtuse angles than the diagonal from the two acute angles.
The rhombus has the same property as the parallelogram.
The kite has a far longer diagonal from the angle enclosed by the two long sides going to the angle enclosed by the two shorter sides, than a line going from the angle enclosed by one shorter and one longer side to the other angle made the same way.
Ratio, proportion and percent unit 4 homework 3 wages hours 1 wage is $9.50 2 $19.00 3 $28.50 4 $38.00
Answer:
(a) The complete table
[tex]\begin{array}{cccccc}Hours & {1} & {2} & {3} & {4} &{5}\ \\ {Amount} & {\$9.50} & {\$19.00} & {\$28.50} & {\$38.00} & {\$47.50} \ \end{array}[/tex]
(b) $38.00
(c) 3 hours
Step-by-step explanation:
Given
[tex]Earnings = \$9.50[/tex] per hour
See attachment for complete question;
Solving (a): Complete the table
To complete the table, we simply multiply the earnings by the number of hours.
So, we have:
[tex]Hours = 2 \to Earnings = \$9.50 * 2 = \$19.00[/tex]
[tex]Hours = 3 \to Earnings = \$9.50 * 3 = \$28.50[/tex]
[tex]Hours = 4 \to Earnings = \$9.50 * 4 = \$38.00[/tex]
[tex]Hours = 5 \to Earnings = \$9.50 * 5 = \$47.50[/tex]
Solving (b): Earnings, if Megan works for 4 hours
In (a) above, we have:
[tex]Hours = 4 \to Earnings = \$9.50 * 4 = \$38.00[/tex]
This implies that Megan will earn $38.00
Solving (c): Hours to earn $28.50
In (a) above, we have:
[tex]Hours = 3 \to Earnings = \$9.50 * 3 = \$28.50[/tex]
This implies that Megan will work for 3 hours to earn $28.50
school has 8 periods a day each of 45 minutes’ duration. How long would each period be, if the school has 9 periods a day, assuming the number of school hours to be the same?
Answer:
40 min per period
Step-by-step explanation:
When it has 8 periods :
Total time = 45 min per period for 8 period
Total time = 45 × 8 min
When it has 9 periods : let each period be of x min
Total time = x min per period for 9 period
Total time = x × 9 min
As total time remains same,
45 × 8 = x × 9
5 x 8 = x
40 = x

Answer:
[tex]6(x-10)(x+9)[/tex]
Step-by-step explanation:
First, make A equal one by factoring out the greatest common factor, 6. This makes the new expression [tex]6(x^{2} +x-90)[/tex]. Then, factor the remaining polynomial by finding two numbers that multiply to -90 and add to 1. These two numbers are -10 and 9. So, add each term to x and then multiply to get the final answer, [tex]6(x-10)(x+9)[/tex].
