A building that is used for storage has the dimensions shown. What is the volume of the building?

Answer:

slope = - 4

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 ) = (4, - 9 ) and (x₂, y₂ ) = 1, 3 )

m = [tex]\frac{3-(-9)}{1-4}[/tex] = [tex]\frac{3+9}{-3}[/tex] = [tex]\frac{12}{-3}[/tex] = - 4

Answer:

[tex]m=-4[/tex]; the slope is -4

Step-by-step explanation:

[tex]slope=\frac{rise}{run} =\frac{y^2-y^1}{x^2-x^1}[/tex]

coordinates: (4,-9) (1,3)

[tex]\frac{3-(-9)}{1-4}=\frac{-12}{-3} =-4[/tex]

= -4 is your answer

Since Sally replaces the card after each draw, there are 52 choices for each card that can be drawn.

In a standard deck of cards, there are 4 aces. Then the probability of drawing an ace is 4/52 = 1/13. The same reasoning applies to drawing a queen or a six. Then the probability of drawing an ace, queen, and six (in that particular order) is 1/13³.

But Sally can also draw these 3 specific cards in any order to end up with the same hand. There are 3! = 6 ways of doing so:

AQ6, A6Q, QA6, Q6A, 6AQ, 6QA

That is, 3 choices for the first card; 2 choices for the second; and 1 for the third, so a total of 3 • 2 • 1 = 3! = 6 hands.

Then the probability of getting a hand consisting of an ace, queen, and six is

3! • 1/13³ = 6/2197 ≈ 0.002731

Answer:

[tex]x=5,\frac{-9+\sqrt{255}i }{4} ,\frac{-9-\sqrt{255}i }{4}[/tex]

Step-by-step explanation:

1) Move all terms to one side.

[tex]2x^{3} -x^{2} -3x-210=0[/tex]

2) Factor [tex]2{x}^{3}-{x}^{2}-3x-210[/tex] using Polynomial Division.

1 -  Factor the following.

[tex]2x^{3} -x^{2} -3x-210[/tex]

2 -  First, find all factors of the constant term 210.

[tex]1,2,3,4,5,6,7,10,14,15,21,30,35,42,70,105,210[/tex]

3) Try each factor above using the Remainder Theorem.

Substitute 1 into x. Since the result is not 0, x-1 is not a factor..

[tex]2*1^{3} -1^{2} -3*1-210=-212[/tex]

Substitute -1 into x. Since the result is not 0, x+1 is not a factor..

[tex]2(-1)^{3} -(-1)^{2} -3*-1-210=-210[/tex]

Substitute 2 into x. Since the result is not 0, x-2 is not a factor..

[tex]2*2^{3} -2^{2} -3*2-210=-204[/tex]

Substitute -2 into x. Since the result is not 0, x+2 is not a factor..

[tex]2{(-2)}^{3}-{(-2)}^{2}-3\times -2-210 = -224[/tex]

Substitute 3 into x. Since the result is not 0, x-3 is not a factor..

[tex]2\times {3}^{3}-{3}^{2}-3\times 3-210 = -174[/tex]

Substitute -3 into x. Since the result is not 0, x+3 is not a factor..

[tex]2{(-3)}^{3}-{(-3)}^{2}-3\times -3-210 = -264[/tex]

Substitute 5 into x. Since the result is 0, x-5 is a factor..

[tex]2\times {5}^{3}-{5}^{2}-3\times 5-210 =0[/tex]

------------------------------------------------------------------------------------------

⇒ [tex]x-5[/tex]

4)  Polynomial Division: Divide [tex]2{x}^{3}-{x}^{2}-3x-210[/tex]  by [tex]x-5[/tex].

                                               [tex]2x^{2}[/tex]                       [tex]9x[/tex]                      [tex]42[/tex]

                                      -------------------------------------------------------------------------

5)  Rewrite the expression using the above.

[tex]2x^2+9x+42[/tex]

[tex](2x^2+9x+42)(x-5)=0[/tex]

3) Solve for [tex]x.[/tex]

[tex]x=5[/tex]

4)  Use the Quadratic Formula.

1 - In general, given [tex]a{x}^{2}+bx+c=0[/tex] , there exists two solutions where:

[tex]x=\frac{-b+\sqrt{b^{2} -4ac} }{2a} ,\frac{-b-\sqrt{b^2-4ac} }{2a}[/tex]

2 -  In this case, [tex]a=2,b=9[/tex] and [tex]c = 42.[/tex]

[tex]x=\frac{-9+\sqrt{9^2*-4*2*42} }{2*2} ,\frac{-9-\sqrt{9^2-4*2*42} }{2*2}[/tex]

3 - Simplify.

[tex]x=\frac{-9+\sqrt{255}i }{4} ,\frac{-9-\sqrt{255}i }{4}[/tex]

5) Collect all solutions from the previous steps.

[tex]x=5,\frac{-9+\sqrt{255}i }{4} ,\frac{-9-\sqrt{255}i }{4}[/tex]

The time taken by the two men will be equal to 26 hours

The speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.

here two men are walking at different speeds like

v₁=6 miles per hour

v₂=10 miles per hour

The time taken by them to separated by the distance of 100 miles each so that both of them separated by the distance of 200 miles.

t₁= {100}/{6}=16.66 hours

t₂= {100}/{10}=10 hours

Given expression:

[tex](-3x^2+4x)+(2x^2-x-11)[/tex]

To simplify the expression, it is needed to open the parentheses.

[tex]\implies (-3x^2+4x)+(2x^2-x-11)[/tex]

[tex]\implies -3x^2+4x+2x^2-x-11[/tex]

Equating the secants :

Answer:

3

Step-by-step explanation:

Theorem:

If two secants intersect outside a circle, then the product of the length of the exterior segment of one secant and the length of that secant equals the product of the corresponding parts of the other secant.

In this case:

10 × (10 + 5x + 2) = 9 × (9 + 7x)

10(5x + 12) = 9(7x + 9)

50x + 120 = 63x + 81

-13x = -39

x = 3

Answer:

F = 53.1°

Step-by-step explanation:

When you consider F as your angle

cos F = adjacent / hypotaneous

or, cos F = EF/DF

We do not have DF right now,

so DF² = DE² + EF²

DF = √ (12² + 9²)

DF = 15

cos F = adjacent / hypotaneous

or, cos F = EF/DF

cos F = 9 / 15

F = cos ⁻¹ (9/15)

F = 53.1°

Using the tangent theorem and the inscribed angle theorem, the measure of angle YAC in the figure is: 70°.

The angle formed at the point of tangency of the radius and the tangent equals 90 degrees based on the tangent theorem.

According to the inscribed angle theorem, an inscribed angle equals the measure of the arc intercepted.

m∠BAY = 1/2(40) [inscribed angle theorem]

m∠BAY = 20°

m∠BAC = 90° [tangent theorem]

m∠YAC = 90 - 20
