Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{12}}}}}$

Step-by-step explanation:

hypotenuse ( h ) = x

Peendicular ( p ) = 10

base ( b ) = 22

Using the Pythagoras theorem

$\boxed{ \sf{ {h}^{2} = {p}^{2} + {b}^{2} }}$

$\dashrightarrow{ \sf{ {x}^{2} = {10 }^{2} + {22}^{2} }}$

$\dashrightarrow{ \sf{ {x}^{2} = 100 + 44}}$

$\dashrightarrow{ \sf{ {x}^{2} = 144}}$

$\dashrightarrow{ \sf{ \sqrt{ {x}^{2} } = \sqrt{144}}}$

$\dashrightarrow{ \sf{x = 12}}$

Hope I helped!

Best regards! :D

Answer:

f(x) = 6x² - 24x + 21

Step-by-step explanation:

The equation of a quadratic function in vertex form is

f(x) = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k ) = (2, - 3 ) , then

f(x) = a(x - 2)² - 3

To find a substitute (1, 3 ) into the equation

3 = 1(1 - 2)² - 3

3 = a(- 1)² - 3

3 = a - 3 ( add 3 to both sides )

6 = a

f(x) = 6(x - 2)² - 3 ← in vertex form

= 6(x² - 4x + 4) - 3

= 6x² - 24x + 24 - 3

f(x) = 6x² - 24x + 21 ← in standard form

two stores sell the same computer for the same orginal price. store a advertises that the computer is 25% off the orginal price.

Gnoma [55]

That means that the discounts are the same
therfor 25% of original=180
multiply both sides by 4 or divide both sides by 0.25
original=720

the equation is
0.25 times original=180

and the original price is $720

The question is incomplete. Here is the complete question.

Semicircles and quarter circles are types of arc lengths. Recall that an arc is simply part of a circle. we learned about the degree measure of an ac, but they also have physical lengths.

a) Determine the arc length to the nearest tenth of an inch.

b) Explain why the following proportion would solve for the length of AC below: $\frac{x}{12\pi } = \frac{130}{360}$

c) Solve the proportion in (b) to find the length of AC to the nearest tenth of an inch.

Note: The image in the attachment shows the arc to solve this question.

Answer: a) 9.4 in

c) x = 13.6 in

Step-by-step explanation:

a) $\frac{arclength}{2\pi.r } = \frac{mAB}{360}$ , where:

r is the radius of the circumference

mAB is the angle of the arc

arc length = $\frac{mAB.2.\pi.r }{360}$

arc length = $\frac{90.2.3.14.6}{360}$

arc length = 9.4

The arc lenght for the image is 9.4 inches.

b) An arc length is a fraction of the circumference of a circle. To determine the arc length, the ratio of the length of an arc to the circumference is equal to the ratio of the measure of the arc to 360°. So, suppose the arc length is x, for the arc in (b):

$\frac{x}{2.6.\pi } = \frac{130}{360}$

$\frac{x}{12\pi } = \frac{130}{360}$

c) Resolving (b):

x = $\frac{130.12.3.14}{360}$

x = 13.6

The arc length for the image is 13.6 inches.

Three boxes are stacked one on top of the other. One box is 6 feet 5 inches tall, one is 4 feet 6 inches tall, and one is 5 feet

3241004551 [841]

Start with adding the feet: 6+4+5=15

then add the inches: 5+6+7=18

18 inches= 1 foot and 6 inches

So its 16 feet and 6 inches

Given: 5n - 42 = 12n; Prove: n= -6 What are the Statements What are the Reasons

asambeis [7]

Answer:

-72=-72

Step-by-step explanation:

5n-42=12n

n=-6

5*(-6)-42 = 12*(-6)

-30-42=-72

-72=-72

So, n= -6 is the right number for this equation
