Answer:


Step-by-step explanation:

Both Shawn and Brielle are correct. The function that represents a vertical stretch by a factor of 9 is f(x) = 9x2. The function that represents a horizontal shrink by a factor of 3 is  

f(x) = (3x)2, which is equal to f(x) = 9x2.  

Additionally, if you wanted to verify that the given points are on the graph of both functions, you could substitute them into the functions to get true statements.

Answer:

  see attached

Step-by-step explanation:

I like to use a spreadsheet for repetitive calculations. The distances are computed from the distance formula:

  d = √((x2 -x1)^2 +(y2 -y1)^2)

The results are shown in the second attachment. The drawing in the first attachment has the lengths rounded to the nearest tenth.

A fireplace arch is to be constructed in the form of a semiellipse. The opening is to have a height of 3 feet at the center and
USPshnik [31]

Answer:

Step-by-step explanation:

Given

Fireplace is in the form of semi-ellipse  with height of 3 ft from center

Length of base=8 ft

if the arch is in the form of ellipse then it can be considered as horizontal ellipse with 2 a and 2 b be length of major and minor axis

2 a =8

a=4 ft

If contractor cover the whole base

then total length of string=2a =8 ft

(b)String should be nailed at focus

focus of ellipse is a e

where e=eccentricity

e=\sqrt{1-(\frac{b}{a})^2}

e=\sqrt{1-(\frac{3}{4})^2}=\frac{\sqrt{7}}{4}

Focus =ae =\sqrt{7}

Thus string should be nailed at 2.64 m from center

padilas [110]

Step-by-step explanation:

shape BCD is an isosceles triangle meaning the base angles will be the same.

CA is a straight line meaning that it is 180

the sum of angles in a triangle always is 180

so

180-36= 144

to find x you need to half 144 as it is the sum of the base angles of the isosceles triangle.

144/2= 72

x=72

the angle just below y is also 72.

as CA is a straight line,

180-72= 108 giving you the answer for y

y= 108

so to make the answer clear

x= 72

y= 108

hope that helped! :)

if you would like to give me a brainliest feel free as im nearly to the end of my goal.

How do you solve X/2-5=10
Afina-wow [57]

Answer: x2-5=10  

Two solutions were found :

                  x = ± √15 = ± 3.8730

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "x2"   was replaced by   "x^2".  

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    x^2-5-(10)=0  

Step by step solution :

Step  1  :

Trying to factor as a Difference of Squares :

1.1      Factoring:  x2-15  

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check : 15 is not a square !!

Ruling : Binomial can not be factored as the difference of two perfect squares.

Equation at the end of step  1  :

 x2 - 15  = 0  

Step  2  :

Solving a Single Variable Equation :

2.1      Solve  :    x2-15 = 0  

Add  15  to both sides of the equation :  

                     x2 = 15

 

When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:  

                     x  =  ± √ 15  

The equation has two real solutions  

These solutions are  x = ± √15 = ± 3.8730  

 

Two solutions were found :

                  x = ± √15 = ± 3.8730
