The point (8, 12) was dilated to become point (2, 3). What was the scale factor?
Answer:
The scale factor is 1/4
Step-by-step explanation:
Here, we are interested in finding the scale factor that helped convert the first point to the second.
Hence, what turned (8,12) to (2,3)
What we shall do here is to simply divide term 2 by term i.e
That would be 2/8 or 3/12 = 1/4
The scale factor was 1/4.
Given that,
The point (8, 12) was dilated to become point (2, 3).
We have to determine,
What was the scale factor?
According to the question,
Scale factors are closely related to the concepts of ratio and proportions.
In ratio and proportions, we multiply or divide a given amount to form a new quantity.
The point (8, 12) was dilated to become point (2, 3).
Therefore,
The scale factor was,
[tex]\rm Scale\ factor = \dfrac{New \ point \ lies \ on \ axis}{Old \ point \ lies \ on \ axis}[/tex]
Substitute the points in the formula for the x-axis,
[tex]\rm \rm Scale\ factor = \dfrac{New \ point \ lies \ on \ x-axis}{Old \ point \ lies \ on \ x-axis}\\\\Scale\ factor = \dfrac{2}{8}\\\\Scale\ factor = \dfrac{1}{4}\\\\[/tex]
And substitute the points in the formula for the y-axis,
[tex]\rm \rm Scale\ factor = \dfrac{New \ point \ lies \ on \ y-axis}{Old \ point \ lies \ on \ y-axis}\\\\Scale\ factor = \dfrac{3}{12}\\\\Scale\ factor = \dfrac{1}{4}\\\\[/tex]
Hence, The scale factor was 1/4.

Let cos(2x) - cos(x) = 0 where 0° < x <180° what are the possible values of x
Answer:
x= 120°
Step-by-step explanation:
cos(2x)-cos(x)=0
[tex]\Rightarrow 2\cos^2x-\cosx-1=[/tex]0 [as [tex]\cos(2x)=2\cos^2x-1[/tex]]
[tex]\Rightarrow 2\cos^2x-2\cosx +\cosx-1=0[/tex]
[tex]\Rightarrow 2\cos x(\cos x-1) +(\cos x-1)=0[/tex]
[tex]\Rightarrow (\cos x-1)(2\cos x +1)=0[/tex]
[tex]\Rightarrow \cos x-1=0 \;or\; 2\cos x +1=0[/tex]
[tex]\Rightarrow \cos x=1 \;or\; \cos x =-1/2[/tex]
[tex]\Rightarrow x=\cos^{-1}1 \;or\; x =\cos(-1/2)[/tex]
For [tex]x=\cos^{-1}1[/tex] and 0° < x <180°
There is no possible value of x.

Given :
Target have apple watches on sale this week for $349 and you get an additional 5% off if you use our red card. Best buy sells them for $389 and you have a coupon for 15% off.
To Find :
How much money would you save by purchasing the watch from the store with the better buy.
Solution :
Selling price at Target :
S.P = $( 349 - 349×0.05)
S.P = $331.55
Selling price at Best buy :
S.P = $( 389 - 389×0.15 )
S.P = $330.65
Amount of price saved = $( 331.55 - 330.65 ) = $0.9 .
Hence, this is the required solution.

The radius of the circle shown below is 3 inches.
What is the area of this circle, in square inches?
Answer:
the area = 28.27 or you can write the answer out as 28.2744 or also 28.27433
Step-by-step explanation:
start with what we know. the formula for solving this is A=pi R squared
so, area= pi (3.1416)
then, multiply that by the radius given, which is 3.
So, 9.4248 × 3 = 28.2744 square inches
or 28.27 sq.in.

O12 inches
Answer: B
4 inches
Step-by-step explanation:
The weight travel from maximum displacement to minimum displacement is 4 inches.
What is Displacement in wave?The relative shift in a wave's position that occurs when it passes through a medium is referred to as wave displacement.
When a wave oscillates, displacement is the movement of a particle or field relative to its resting location. The amplitude of the wave is a measurement and recording of the largest displacement that has place.
Given:
From the graph we can a wave.
Now, we can see that the Wave is 2 inches in crust and 2 inches in trough.
So, the weight travel from maximum displacement to minimum displacement is
= 2 + 2
= 4 inches.

Write the inverse function,
f^-1 (x), for the function
f (x) = 2x + 3
[tex]f(x) = 2x + 3[/tex]
[tex]y = 2x + 3[/tex]
Subtract the sides of the equation minus 3
[tex]y - 3 = 2x[/tex]
Divided the sides of the equation by 2
