Answer:

D) y = 12

Step-by-step explanation:

One can use the angle bisector theorem to solve this problem. The angle bisector theorem states:

[tex]\frac{a_1}{b}=\frac{a_2}{c}[/tex]

Where ([tex]a_1[/tex]) and ([tex]a_2[/tex]) are a part of the side that is intersected by the angle bisector and ([tex]b[/tex]) and ([tex]c[/tex]) are the other two sides in the triangle. Substitute in the given values and solve for the unknown.

[tex]\frac{4}{8}=\frac{6}{y}[/tex]

Simplify,

[tex]\frac{1}{2}=\frac{6}{y}[/tex]

Cross products,

[tex]12=y[/tex]

Answer:

In naming a ray, we always begin with the letter of the endpoint (where the ray starts) followed by another point on the ray in the direction it travels. Since the vertex of the angle is the endpoint of each ray and our vertex is , each of our rays must begin with . Only fails to do so.

Answer:

A ray is a part of a line that has one endpoint and goes on infinitely in only one direction. You cannot measure the length of a ray. A ray is named using its endpoint first, and then any other point on the ray (for example, →BA ).

Answer:

700 m^2

Step-by-step explanation:

If the height is 28, and the base is 50, do the triangle area formula for the area.

1/2 28 * 50 = 14 * 50 = 700

Answer:

I believe it should be 700

Step-by-step explanation:

Formula: B times H times 1/2

Answer:

28

Step-by-step explanation:

A(x) = x * (x + 3)

      = x^2 + 3x

A(4) = 4^2 + 3(4)

       = 16 + 12

       = 28

Answer:

a(4)=4^2+3(4)

a(4)=16+12

a(4) =28 ft ^2

Answer:

Since this triangle seems to be 180 degree, and one angle is 90 degrees and the other is half thslat value (45), the other value will be 45 degrees. It is an Isosceles triangle

Answer:

B) 6/5 or 1 1/5

Step-by-step explanation:

5/9 ÷ 5/3 × 18/5 = 5/9 × 3/5 × 18/5 = 6/5

Answer:

If Angle 1 is 110,

then the second angle to complete the straight angle (180 degrees) is...

180 - 110 = 70

Angle 2 = 110 (same as Angle 1, plus it's obtuse)

Angle 3 = 70 (it's acute)

Angle 4 = 70 (same as Angle3, plus it's acute)

Answer:

Step-by-step explanation:

This is not a function.

A function has to have 1 y associated with each x. This relationship has 2 except for 1 point (the vertex at 3,0).

You can write a domain and range for it.

The domain is

- infinity < x < 3

The range is

-infinity  < x < + infinity.

3.75 times x = 90

90 divided by 3.75= 24

Answer:

Part A: Rewrite the expression by factoring out the greatest common factor. (4 points)

answer:

2y(x³+4x-2x²-8)

Part B: Factor the entire expression completely. Show the steps of your work. (6 points)

answer:

2y(x³+4x-2x²-8)

2y(x³-2x²+4x-8)

2y(x²(x-2)+4(x-2))

2y(x²+4)(x-2)

Answer:

[tex]Width = p + 4[/tex]

Step-by-step explanation:

Given

[tex]Area = p^2 + 9p + 20[/tex]

[tex]Length = p + 5[/tex]

Required

Determine the width

The area of a rectangle is:

[tex]Area = Length * Width[/tex]

This gives:

[tex]p^2 + 9p + 20= (p+5)* Width[/tex]

Expand

[tex]p^2 + 4p + 5p + 20= (p+5)* Width[/tex]

Factorize

[tex]p(p + 4) + 5(p + 4)= (p+5)* Width[/tex]

[tex](p + 5) (p + 4)= (p+5)* Width[/tex]

Divide both sides by p + 5

[tex]p + 4= Width[/tex]

[tex]Width = p + 4[/tex]

Answer:

θ = 47.312447

Step-by-step explanation:

I assume you are trying to find θ

The first thing you do is to find θ is to do the acos of 0.678

θ = acos(0.678)

θ = 47.312447

Answer: A

Step-by-step explanation:

I just took the USATESTPREP quiz and that is the answer.

 Option (C) will define the changes in the graph of the function with the values of 'd'.

 Given function in the question → y = alog(x + c) + d

Rules for the translation of a function,

 Hence, in the given function y = alog(x + c) + d, positive value of 'd' will define the shifting of the parent function upwards.

And for the negative value of 'd' will define the shift of the function downwards.

     Option (C) will be the correct option.

Answer:

Step-by-step explanation:

Make the denominators same by multiplying the fraction with a number that will make the denominators equal i.e 3 for first fraction and 4 for the second fraction.

Answer:

h = 65, g = 115, m = 49, k = 131

Step-by-step explanation:

h and 115 are supplementary angles, so 180 - 115 is 65 degrees.

g and 115 are vertical angles, so both should be 115 degrees.

m and 131 are supplementary angles, so 180 - 131 = 49 degrees.

k and 131 are vertical angles, so both should be 131 degrees.

a-1.- location 1: =0.01- location 2: =0.113

a-2. F= 0.08849

b.  A. yes.

c.  t= -1.020

d. B. No.

Step-by-step explanation:

Location1(%C)             Location2(%C)

      x                  x²                      y                     y²

1   10.40           108.16                  10.10          102.01

2  10.20           104.04                  10.90         118.81

3  10.30           106.09                 10.20          104.04

4  10.40            108.16                  10.70         114.49

5  10.20            104.04                  10.40       108.16        

∑   51.5              530.49                  52.3         547.51      

x`= ∑x/n1 = 51.5/5= 10.3;    y`= ∑y/n2= 52.3/5= 10.46

Sx² = 1/n1-1[ ∑x² - (∑x)²/n1] = 1/4[  530.49 - (51.5)²/5]

        = 1/4[ 530.49 - 530.45] = 0.01

Sy² = 1/n2-1[ ∑y² - (∑y)²/n2] = 1/4[  547.51 - (52.3)²/5]

        = 1/4[ 547.51 - 547.058] = 0.113

F= Sx²/Sy²= 0.01/0.113= 0.08849

The critical region is F ≥ F(0.025) (5,5)= 7.15

and  F ≤ 1/F(0.025) (5,5) = 1/7.15= 0.13986

Since the calculated value of F =0.08849 falls in the critical region we conclude that  the two standard deviations for the locations significantly different at the 95% confidence level.

c.   t= x1`-x2`/ sqrt ( s₁²/n₁ + s₂²/n₂)

t= 10.3-10.46/ sqrt( 0.01/5 +0.113/5)

t=- 0.16/0.15684

t= -1.020

d.  The calculated value t= -1.020   does not fall in the the critical region

t (0.025) (4) = ±2.776  we conclude that the  means for the two different locations are not significantly different at the 95% confidence level.
