The difference in length of a spring on a pogo stick from its non-compressed length when a teenager is jumping on it after θ seconds can be described by the function f of theta equals 2 times cosine theta plus radical 3.
Part A: Determine all values where the pogo stick's spring will be equal to its non-compressed length.
Part B: If the angle was doubled, that is θ became 2θ, what are the solutions in the interval [0, 2π)? How do these compare to the original function?
Part C: A toddler is jumping on another pogo stick whose length of their spring can be represented by the function g of theta equals 1 minus sine squared theta plus radical 3 period At what times are the springs from the original pogo stick and the toddler's pogo stick lengths equal?
Answers
The given function for the difference in length is presented as follows;
[tex]f( \theta) = 2 \cdot cos( \theta) + \sqrt{3} [/tex]
When the pogo stick will be equal to its non compressed length, the difference is zero, therefore;
[tex]f( \theta) = 2 \cdot cos( \theta) + \sqrt{3} = 0[/tex]
[tex] 2 \cdot cos( \theta) = - \sqrt{3} [/tex]
[tex]\theta= arccos \left( \frac{ - \sqrt{3} }{2} \right) [/tex]
Which gives;
[tex] \theta = \frac{12 \cdot \pi \cdot n1 + 5\cdot \pi}{6} [/tex]
[tex] \theta = -\frac{12 \cdot \pi \cdot n1 + 5\cdot \pi}{6} [/tex]
Part B; If the angle was doubled, we have;
[tex]f( \theta) = 2 \cdot cos(2 \cdot \theta) + \sqrt{3} = 0[/tex]
Therefore;
[tex] 2 \cdot cos(2 \cdot \theta) = - \sqrt{3} [/tex]
Which gives;
[tex] \theta = \frac{12 \cdot \pi \cdot n1 + 5\cdot \pi}{12} [/tex]
[tex] \theta = -\frac{12 \cdot \pi \cdot n1 + 5\cdot \pi}{12} [/tex]
Between 0 and 2•π, we have;
[tex] \theta = \frac{5\cdot \pi}{12} [/tex]
[tex] \theta = \frac{ 17\cdot \pi}{12} [/tex]
Part C;
The toddler's pogo stick is presented as follows;
[tex]g( \theta) = 1- son^2( \theta) + \sqrt{3} [/tex]
Integrating the original function between 0 and theta gives;
[tex]2 \cdot sin( \theta) + \sqrt{3}\cdot \theta [/tex]
The original length =
Therefore, when the lengths are equal, we have;
[tex]1- son^2( \theta) + \sqrt{3} = 2 \cdot sin( \theta) + \sqrt{3}\cdot \theta [/tex]

A woman is standing 12 feet from a sculpture. The angle of elevation from her eyes to the top of the sculpture is 35º. If the woman's eyes are 5 feet 6 inches off the ground, how tall is the sculpture? Round answer to the nearest thousandth of a foot.
Answers
Answer:
13.903 feet
Step-by-step explanation:
Let the height from the woman's eyes to the top of the sculpture be represented by x.
So that,
Tan 35 = [tex]\frac{x}{12}[/tex]
x = Tan 35 x 12
= 0.70021 x 12
= 8.4025
x = 8.403 feet
The height of the sculpture = The woman's eye level to the ground + x
= 5 feet 6 inches + 8.403 feet
= 5.50 feet + 8.403 feet
= 13.903 feet
Thus, the sculpture has a height of 13.903 feet.
Sara bought 12 feet of fabric to make curtains. She needs to cut it into 1/4 foot sections. How many sections of fabric will she have.

Step-by-step explanation:
Here is a two-way table that represents the given data:
Look at the pic
To create this table, we first divided the students into two categories: those who play a sport and those who do not. Then, we further divided each category into those who play in the school band and those who do not.
From the table, we can answer the following questions:
How many students did Sam survey in total?
To find the total number of students surveyed, we can add up the values in the table:
14 + 5 + 3 + 9 + 10 = 41
Therefore, Sam surveyed a total of 41 students.
How many students played a sport but did not participate in the school band?
From the table, we can see that 14 students played a sport, and 5 of those also participated in the school band. Therefore, the number of students who played a sport but did not participate in the school band is:
14 - 5 = 9
So, 9 students played a sport but did not participate in the school band.
How many students did not play a sport but participated in the school band?
From the table, we can see that 8 students played in the school band, and 3 of those did not play a sport. Therefore, the number of students who did not play a sport but participated in the school band is:
8 - 3 = 5
So, 5 students did not play a sport but participated in the school band.

A scale is a set of numbers that help to measure or quantify objects. A scale on the graph shows the way the numbers or pictures are used in data.
Given data ,
The distance between Louisville and Nashville = 1 3/4 inches
Scale of the map = 1 in : 100 miles
Now , 1 inch = 100 miles on the map
And , 1 3/4 = 7 / 4 inches
So , 7 / 4 inches = ( 7 / 4 ) x 100 miles
= 1.75 x 100 miles
= 175 miles

PLEASE HELP, I DON'T UNDERSTAND THE WORDING
Answers
Answer:
C. 8 miles per hour
Step-by-step explanation:
It takes Diego [tex]\frac{1}{8}[/tex] of an hour to complete the lap = [tex]\frac{1}{8}[/tex] x 1 hour = [tex]\frac{1}{8}[/tex] hour
Distance of the track = 1 mile long
The speed of an object expresses the ratio of distance moved to time taken to cover the distance.
i.e speed = [tex]\frac{distance}{time taken}[/tex]
= [tex]\frac{1}{\frac{1}{8} }[/tex]
= 8
Speed = 8 mile per hour
Therefore, Diego's bike has a speed of 8 miles per hour.

The upper-left coordinates on a rectangle are (- 8, 8) and the upper-right coordinates are (- 3, 8) The rectangle has an area of 15 square units
Answers
Answer:
See attachment for diagram
Step-by-step explanation:
Given
[tex](x_1,y_1) = (-8,8)[/tex]
[tex](x_2,y_2) = (-3,8)[/tex]
[tex]Area = 15[/tex]
Required
Draw the rectangle on a coordinate plane --- (missing from the question)
First, we calculate the distance between the given pairs.
[tex]D = \sqrt{(x_1 - x_2)^2 + (y_1-y_2)^2}[/tex]
[tex]D = \sqrt{(-8-(-3))^2 + (8-8)^2}[/tex]
[tex]D = \sqrt{25}[/tex]
[tex]D = 5[/tex]
So, the distance between the given pairs is 5 units... Let this be the length of the rectangle.
Using:
[tex]Area = Length * Width[/tex]
[tex]15 = 5 * Width[/tex]
[tex]Width = \frac{15}{5}[/tex]
[tex]Width = 3[/tex]
The width is 3 units.
This implies that the opposite sides of the rectangle are either 3 units down or 3 units up the given pairs.
Assume they are 3 units up.
[tex](x_1,y_1) = (-8,8)[/tex] and [tex](x_2,y_2) = (-3,8)[/tex]
[tex](x_3,y_3) = (x_1,y_3 + 3) = (-8,8+3) = (-8,11)[/tex]
[tex](x_4,y_4) = (x_2,y_2 + 3) = (-3,8+3) = (-3,11)[/tex]

Answers
Answer:

Step-by-step explanation:
since those 2 angles make up 180 degrees turn it into an equation
20t + 5 + 15t = 180
combine like terms 20t + 15t = 35t
the equation is now 35t + 5 = 180
subtract 5 from both sides, 5 - 5=0, 180 - 5 = 175
35t = 175
now divide each side by 35, 35t/35 = t, 175/35= 5
t = 5
hope this helps :)
Answer:
5
Step-by-step explanation:
Line (which has the the equation)= 180
So,
15t + 20t + 5 = 180
35t + 5 = 180
35t = 180 - 5
35t = 175
t = 175/35
