Answer:
27*2/3=18
18*2/3=12
Step-by-step explanation:
I would look at the ratio of two terms
and the difference of two terms
to see if there might be a pattern
for example, 27, 18, 12
the difference between 27 and 18 is 9
the difference between 18 and 12 is 6
That is not a constant difference.
Let's try ratios:
27/18 = 1.5
18/12 = 1.5
that looks promising... we get the same ratio
so on the next bounce, expect
18/x = 1.5
maybe it's easier if we flip the ratio 1.5 (3/2) to 2/3 and so
18= 2/3 * 27
12= 2/3* 18 = 2/3 * 2/3 * 27
If we try to make a pattern
first peak = (2/3)^0 * 27
2nd peak = (2/3)^1 *27
3rd peak = (2/3)^2 * 27
Answer:
There is a common ratio of 2/3 between the height of the ball at each bounce. So, the bounce heights form a geometric sequence: 27, 18, 12. Two-thirds of 12 is 8, so on the fourth bounce, the ball will reach a height of 8 feet.

The vertex angle of an isosceles triangle measures 40°. What is the measure of a base angle?
Answer:
70°
Step-by-step explanation:
In an isosceles triangle the 2 base angles are congruent , thus
base angle = [tex]\frac{180-40}{2}[/tex] = [tex]\frac{140}{2}[/tex] = 70°
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.

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.

Target hs 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. How much money would you save by purchasing the watch from the store with the better buy?
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.
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.
For [tex]x =\cos(-1/2)[/tex] and 0° < x <180°
The possible value of x is
x= 120°
