=16×9×6

=864 inches

Answer:

864 is the volume

Step-by-step explanation:

You can find the answer by applying the volume formula Length x Width x Height.

16x9x6=  864

It does not matter in which way you put the order of length, width and height.

Answer:

5 2/3

Step-by-step explanation:

3x-4=13

    +4  +4

Add 4 to -4 and 13.

If you add a positive # to a negative one you get a positive number so -4+4 is 0

3x=17

divide 3 and 17

you get 5 2/3

k=7

given a quadratic polynomial

ax^2+bx+c

the sum of the roots is given by -(b/a)

and the product of the roots as (c/a)

hence we get sum of roots as -(-(k+6)/1) and product of roots as (2(2k-1))/1

since the sum is equal to half the Product then we get

k+6=2k-1 and solving for k we get 7

Answer:

[tex]\displaystyle p > \frac{1}{4}[/tex].

Step-by-step explanation:

Expand the left-hand side of this equation:

[tex]p\, (x + 1)\, (x - 3) = p\, \left(x^2 - 2\, x - 3\right) = p\, x^2 - 2\, p\, x - 3\, p[/tex].

Collect the terms, so that this quadratic equation is in the form [tex]a\, x^2 + b\, x+ c = 0[/tex]:

[tex]p\, x^2 - 2\, p\, x - 3\, p = x - 4\, p - 2[/tex].

[tex]p\, x^2 - (2\, p + 1)\, x + (p + 2) = 0[/tex].

In this equation:

Calculate the quadratic discriminant of this quadratic equation:

[tex]\begin{aligned}b^2 - 4\, a\, c &= (-(2\, p + 1))^2 - 4\, p\, (p + 2) \\ &= 4\, p^2 + 4\, p + 1 - 4\, p^2- 8\, p = -4\, p + 1\end{aligned}[/tex].

A quadratic equation has no real root if its quadratic discriminant is less then zero. As a result, this quadratic equation will have no real root when [tex]-4\, p + 1 < 0[/tex]. Solve for the range of [tex]p[/tex]:

[tex]\displaystyle p > \frac{1}{4}[/tex].

Step-by-step explanation:

graph a shows reflection across the y axis

Answer:

the correct answer is B

Step-by-step explanation:

the image for A is incorrect because that would be reflecting across the x-axis

the image for B is correct because it is literally going across the y-axis (ik it sounds very simple but it's true)

the image for C is incorrect because it doesn't even go across the y-axis or x-axis, it's only in the  third quadrant

Answer:

slope = 1

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, - 5) and (x₂, y₂ ) = (- 3, - 6)

m = [tex]\frac{-6-(-5)}{-3-(-2)}[/tex] = [tex]\frac{-6+5}{-3+2}[/tex] = [tex]\frac{-1}{-1}[/tex] = 1

Answer:

the forth one is linear

Step-by-step explanation:

Answer:

y=2x+1

Step-by-step explanation:

Answer:

1) On the x-axis, the arm span is plotted. On the y-axis, the height is plotted. It is chosen to be that way because the numbers on that have been assigned on the x-axis increase and decrease in a small amount, while the numbers on the y-axis increase and decrease in a huge amount.

2) (lolz i cant show u my work but i will try my best with explanations even tho ian allat.) So, Using the slope formula, I got a the equation y=x+15. The equation was determined with the formula m=y2-y1/x2-x1. The points that were used included (37,40) and (47,50). After finding the slope, I did the best guess for the y-intercept, which is known as b in y=mx+b.

3) The slope of the line represents the time it takes for the arm span and the height. The y-intercept represents the height that the arm span starts developing or gets bigger.

4) It fits perfectly

5) The data is pretty inconsistent.

6)  About 68-69 inches tall

7)About 71-72 inches wide

Answer:

3. 12.5π + 100

6. 25π + 250

Step-by-step explanation:

3. So you can first calculate the area of the square, which is 100.

Then you have to calculate the semicircle.

You can see that the diameter is 10.

The radius is 5.

The area of the semicircle is 12.5π

Total area is 12.5π + 100

6. You have a one rectangle and two semicircles.

You can calculate the area of the semicircles first.

25π

Then, you have to see how much the width of the rectangle is.

You can see that the total width is 35, and the radius of each semicircle is 5.

35 - 5 - 5 = 25

The width is 25 so the area of the rectangle is 250.

The total is 25π + 250.

Answer:

The answer is [tex]\frac{1}{6}a - \frac{1}{6}[/tex] .

Step-by-step explanation:

Solve the following equation:

[tex]-\frac{2}{3}a + \frac{5}{6}a - \frac{1}{6}[/tex]

Combine [tex]-\frac{2}{3} a[/tex] and [tex]\frac{5}{6} a[/tex] :

[tex]-\frac{2}{3}a + \frac{5}{6}a - \frac{1}{6}[/tex]

[tex]\frac{1}{6}a - \frac{1}{6}[/tex]

So, the answer is [tex]\frac{1}{6}a - \frac{1}{6}[/tex] .

Answer:

1/6a-1/6

Answer:

I'm not sure what to do here

Step-by-step explanation:

Step-by-step explanation:

Adding 10 to both sides of the original equation gets us q = 6(r + 1) + 10. Since q is equal to h(r), we get h(r) = 6(r + 1) + 10 = 6r + 16.

Answer:

<CAB and <DAE are vertical angles

<EAB and <CAD are vertical angles

Step-by-step explanation:

this is because they are formed by the prolongation of the sides of the other angles and are opposite to them on the other side of the vertex.

Options B and D are correct. The vertical angles are ∠CAD and ∠BAE AND ∠EAB and ∠CAD.

Vertical angles are angles that are opposite to each other in line geometry. The size of the angles must be the same.

According to the diagram shown, we can see that ∠CAD and ∠BAE are opposite to each other with similar measures.

Hence the vertical angles are ∠CAD and ∠BAE AND ∠EAB and ∠CAD.

Hi!

The negative signs cancel out iin the equation to make a positive 7.

The 4 is already positive.

So that makes it 4 + 7!

Or 7 +4!
