Answer:

[tex]h = \sqrt{72}in[/tex]

Step-by-step explanation:

We have a right triangle with long side of 11in and smaller sides 14in/2=7in and h.

We know that

[tex]h^2 + (7in)^2 = (11in)^2\\h^2 = 121in^2 - 49in^2 = 72in^2\\h = \sqrt{72}in[/tex]

Answer:

C(2, 5 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then midpoint is

( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )

Here (x₁, y₁ ) = A(- 4, 8) and (x₂, y₂ ) = B(8, 2) , then

midpoint = ( [tex]\frac{-4+8}{2}[/tex], [tex]\frac{8+2}{2}[/tex] ) = ( [tex]\frac{4}{2}[/tex], [tex]\frac{10}{2}[/tex] ) = C(2, 5 )

Answer:

[tex]\sqrt{41}[/tex]

Step-by-step explanation:

Answer:

x-intercept (s):

For this case h (x) = 0

x2 - 2x - 8 = 0

(x-4) * (x + 2) = 0

x1 = 4

x2 = -2

y-intercept:

For this case x = 0

h (0) = (0)2 - 2 (0) - 8

h (0) = - 8

vertex:

We derive the equation:

h '(x) = x2 - 2x - 8

h (x) = 2x - 2

We match zero:

2x-2 = 0

x = 2/2

x = 1

We evaluate the function for x = 1

h (1) = (1)2 - 2 (1) - 8

h (1) = 1 - 2 - 8

h (1) = -9

The vertex is:

(1, -9)

axis of symmetry of the function:

x = 1

Answer:6

Step-by-step explanation:

The number of hours when the amount Andrew and dave pay for the rentals be equal will be 6 hours.

Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).

Then the equation of the line is given as,

[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]

From the equation, the two points of Dave's line will be (0, 6) and (2, 9). Then the equation is given as,

(y - 6)[(9 - 6) / (2 - 0)](x - 0)

y = 1.5x + 6

From the equation, the two points of Andrew's line will be (0, 3) and (1, 5). Then the equation is given as,

(y - 3) = [(5 - 3) / (1 - 0)](x - 0)

y = 2x + 3

The number of hours when the amount Andrew and dave pay for the rentals be equal will be calculated as,

2x + 3 = 1.5x + 6

0.5x = 3

x = 6 hours

The number of hours when the sum Andrew and dave pay for the rentals be equivalent will be 6 hours.

#SPJ2

Answer:

$1100

Step-by-step explanation:

Let the total budget = b

amount spent on props + amount spent on equipment = total budget

If 37% of the budget was spent on equipment

The percentage spent on props = 100% - 37% = 63%

63% of the total budget is $693

the above sentence presented as an equation gives :

63/100 x b = 693

to find b, divide both sides of the equation by 100/63

b = $1100

Answer:

[tex](3,0)[/tex]

Step-by-step explanation:

The x-intercept(s) of a function is the point(s) where the function intersects the x-axis, or the horizontal axis. If we look at the graph, we see that the function intersects the x-axis when [tex]x=3[/tex] (we know this because [tex]3[/tex] is directly in between [tex]2[/tex] and [tex]4[/tex]) and [tex]y=0[/tex], so the answer is [tex](3,0)[/tex].

Answer:

$2.55

Step-by-step explanation:

He Sale flyer for cereal at a local grocery store states: Cereal 3 for $7.65 or 1 for $2.69.

How much is the unit price if you buy using the 3-box deal?

The unit price for the 3 box deal is :

3 boxes = $7.65

1 box = $x

Cross Multiply

3 × x = 1 × $7.65

3x = $7.65

x = $7.65/3

x = $2.55

The unit price for the 3 box deal is $2.55

Answer:It is 154 square inches. and 38 width

Step-by-step explanation:

Answer:

{5 ft, 18 ft}, {1 ft, 90 ft}, {9 ft, 10 ft}

Step-by-step explanation:

Represent the length and width by L and W respectively.

Then one requirement may be expressed as L > W.

The other requirement is L * W = 90 ft^2.

Let's temporarily replace W in this equation with L:

L^2 = 90 ft^2, so that L must be the positive square root of 90 ft^2:

L = √(90 ft^2) ≈ 9.5

Since L must be greater than W, we can write L > 9.5 ft.  The nearest integer L would be 10, in which case the nearest integer W would be 9, which means that the area of the stage would be 90 ft^2 (as required).

{9 ft, 10 ft} are possible whole number measurements for L and W.  Here W < L, as required, and L and W are both integers.

{5 ft, 18 ft} is another possible set of measurements.

So is {1 ft, 90 ft}.
