Answer:

[tex]g(x) = \frac{6}{5}x + 8[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 6x + 8[/tex]

[tex]k = 5[/tex] --- horizontal stretch factor

Required

Find g(x)

When a function is stretched horizontally by k, the resulting function will be:

Rule: [tex]g(x) = f(\frac{1}{k}x)[/tex]

So, we have:

[tex]g(x) = f(\frac{1}{5}x)[/tex]

Solve for: [tex]f(\frac{1}{5}x)[/tex]

[tex]f(\frac{1}{5}x) = 6 * \frac{1}{5}x + 8[/tex]

[tex]f(\frac{1}{5}x) = \frac{6}{5}x + 8[/tex]

Recall that:

[tex]g(x) = f(\frac{1}{5}x)[/tex]

[tex]g(x) = \frac{6}{5}x + 8[/tex]

Answer:

f(1/5x) = 6 ^1/5x  +8

Step-by-step explanation:

A horizontal stretch by a factor of 5 means that the input, or x, is multiplied by : 1/5

Answer:

D

Step-by-step explanation:

If a shape is rotated 180* clockwise around the origin, then it is basically being flipped around which means that the current coordinates would be the opposite of what they currently are. So (3,4) would be (-3, -4).

I think that is the right answer but I'm not 100% sure sorry!

Answer:

15 more weeks

Step-by-step explanation:

425 - 125 (what shes already saved)

300 divided by 20 (amount shes saving each week)

Result is 15, so 15 more weeks.

Hope this helped :)

If you mean how many weeks total, 125 according to the 20 dollars a week would bring it 22 weeks i think.. since the answer answer is 21.2 weeks exactly when you divide 425 by 20.

Given:

The figure of two semicircles with diameters 6 cm and 5 cm.

To find:

The area of the combined figure.

Solution:

It is given that the diameters of the semicircles are 6 cm and 5 cm so their radii are 3 cm and 2.5 cm respectively.

Area of a semicircle is:

[tex]A=\dfrac{1}{2}\pi r^2[/tex]

So, the combined area of two semicircles with radii 3 cm and 2.5 cm is:

[tex]Area=\dfrac{1}{2}\pi (3)^2+\dfrac{1}{2}\pi (2.5)^2[/tex]

[tex]Area=\dfrac{1}{2}\pi (9)+\dfrac{1}{2}\pi (6.25)[/tex]

[tex]Area=14.137167+9.817477[/tex]

[tex]Area=23.954644[/tex]

Round the value to the nearest tenth (one decimal place.

[tex]Area\approx 24.0[/tex]

Therefore, the area of given figure is 24.0 sq. cm.

Step-by-step explanation:

Answer:

1). 4.2    2). 7.65    3). 14.14

Step-by-step explanation:

1). √(y2 - y1)² + (x2 - x1)²

√[-1 - (-4)]² + [-3 - (-6)]²

√(3)² + (3)²

√9 + 9

√18

= 4.2

2). √(2.5 - 1)² + ( -4 - 3.5)²

√(1.5)² + (-7.5)²

√(2.25) + (56.25)

√58.5

= 7.65

3).√(5 - (-5)² + (-5-5)²

√(10)² + (-10)²

√(100) + (100)

√200

= 14.14

Step-by-step explanation:

Answer:

[tex]sin(\theta_1) = \dfrac{\sqrt{357} }{29}[/tex]

Step-by-step explanation:

The parameters of the angle θ₁ are;

The location of θ₁ = Quadrant II

cos(θ₁) = -22/29

We note the following;

1) The sine of an angle in quadrant II is positive

2) The cosine of an angle in quadrant II is negative,

2) The cos of an angle = The adjacent leg length to the reference angle divided by the hypotenuse length of a right triangle

3) With regards to the right triangle for finding cos(θ₁)

The adjacent leg length = -22 (The x-axis is negative in quadrant II)

The hypotenuse length = 29

The negative sign is obtained from the value of cosine in the quadrant

Therefore, by Pythagoras' theorem, for a right triangle, we have;

The opposite leg length to 'θ₁' = √(29² - 22²) = √(357)

[tex]sin\angle X = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]

Therefore, we have;

[tex]sin(\theta_1) = \dfrac{\sqrt{357} }{29}[/tex].

Answer:

D 70

Step-by-step explanation:

Hello there!

A triangle formed inside of a circle using the diameter ( segment RQ ) is a right triangle

Meaning that the angle across from the hypotenuse ( diameter ) is a right angle ( = 90 degrees )

That being said we are given two angles (90 and 20 ) so we can easily calculate the measure of the missing angle

Remember the sum of the angles in a triangle is equal to 180 so we can find the missing angles by subtracting the given angles ( 90 and 20 in this case ) from 180

angle PRS = 180 - 90 - 20

180 - 90 = 90

90 - 20 = 70

Therefore your answer is D. 70

Answer:

76

Step-by-step explanation:

Put the numbers in order from least to greatest.

72, 73, 75, 76, 76, 79, 83, 86

Then, cross off each number at each end until you reach the one in the middle. Which, since they are the same, is 76.

Answer: 3.32276 units squared

Step-by-step explanation:

area of total sector=(pi*r^2)/360

=2^2 * 120pi /360

=4*120/360 * pi

=4.1887902

area of the triangle=(1/2)*base*height

the height is 1 (because you can divide the triangle down the middle to make a 30 60 90 triangle, and the sin(30)=x/2, so 2sin(30)=x, x=(1/2)*2

the base is equal to [tex]\sqrt{3}[/tex] because the base of the 30 60 90 triangle is 2sin(60), and sin60 is [tex]\sqrt{3}[/tex]/2, so you have to double that to get the area of the 120 degree triangle.

the area of the triangle is (1/2)*1*[tex]\sqrt{3}[/tex]=[tex]\sqrt{3} /2[/tex]=0.866025

so the difference is 4.1887902-0.866025

=3.32276 units squared
