3. A scientist recorded the movement of a pendulum for a period of time. The scientist began recording when
the pendulum was at its resting position. The pendulum then moved right (positive displacement) and left
(negative displacement) several times. The pendulum took 5 s to swing to the right and then return to its
resting position. The pendulum's furthest distance to either side was 7 in. Graph the function that represents
the pendulum's displacement as a function of time.

Answer:
75° = x°
Step-by-step explanation:
there are 4 right angles
so with the line being linear, the angle on each side is 15°. so you take
90° (right angle) - 15° (the inside angle) = 75°. or the outside angle
do 75 + 15 to check

Given Data set of people who attend the concert has a mean of 36.4.
What is the mean?the sum of the values by adding them all up. Divide the sum by the number of values in the data set is known as the mean.
Given The data set shows the number of people who attended a concert over a period of 10 days.
12, 35, 27, 55, 22, 23, 60, 49, 15, 66
the Sum of the given data set = 364
from the general formula of the mean
mean = (sum of data)/ number of data
Given the number of data = 10
Thus
Mean = 364 / 10
Mean = 36.4
therefore, the Mean of the given Data set is 36.4.

The school gains 20p from each player, but has an expected payout to the player of 7.5p, so the net gain per game to the school is ...
20p -7.5p = 12.5p

Answers
Answer:
x = 30
y = 114
Step-by-step explanation:
considering DC || AB the sum of angle <D and angle <A must be equal to 180 because they are supplementary:
5x + x = 180 add like terms
6x = 180 divide both sides by 6
x = 30
Same goes for angle <C and angle <B:
y + 2.2x = 180 we know the value of x is 30
y + 2.2*30 = 180
y + 66 = 180 subtract 66 from both sides
y = 114

The MRA volleyball team decides to raise some extra money for their trip by horganizing a cookie sale. The cost to make the cookies is $45 and the team is charging $0.25 a cookie. How many cookies must be sold to make a profit of at least $100? write an inequality.
Answers
Answer:
Inequality:[tex]0.25x\geq 145[/tex]
Answer: At least 580 cookies
Step-by-step explanation:
Lets say they sell x cookies.
Now, that means they will make 0.25x as their income(the price multiplied by the number of cookies).
We know that totally they need to make 100+45 dollars, because that is what will give them a $100 profit. So they need to make $145
Now just set 0.25x equal to $145.
[tex]0.25x=145[/tex], and now solve
[tex]x=145*4[/tex]
[tex]x=580[/tex]
For an inequality, we could just say that:
[tex]0.25x\geq 145[/tex]

We can make it to where one square is 14 ft long and 10 ft wide.
The other square can be 16 ft long and 4 ft wide
Find the areas of those two squares by multiplying width and length
14 x 10 = 140

Suppose the measure of <4 was 105º. Which
answer choice below represents is the measure of
<1?
A. 180°
B. 105°
C. 75°
D. 15°
Answers
Answer:
C
Step-by-step explanation:
Angle 1 and angle 4 sit on the same straight line which means
<1 + <4 = 180
We are given that <4 = 105 degrees. So the equation above becomes.
<1 + 105 = 180 Subtract 105 from both sides
<1 = 180 - 105
<1 = 75

Answer:
For ∆1 , x = 20 , y = 10√2
For ∆2 , x = y = 11
Step-by-step explanation:
Here in the first right angled triangle one of the angles is 45°. And one of the known side is 20 . We need to find out the value of x and y.
Since two angles are 90° and 45° , therefore the third angle will be 45° . And as we know that the sides opposite to equal angles are equal. Therefore ,[tex]\rm\longrightarrow \underline{\underline{ x =20}}[/tex]
Again , we use ratio of sine to find y , as ,
[tex]\rm\longrightarrow sin45^o =\dfrac{p}{b}\\ [/tex]
[tex]\rm\longrightarrow \dfrac{1}{\sqrt2}=\dfrac{20}{y}\\ [/tex]
[tex]\rm\longrightarrow y =\dfrac{20}{\sqrt2}=\dfrac{2\times 10}{\sqrt2}\\ [/tex]
[tex]\rm\longrightarrow \underline{\underline{ y = 10\sqrt2}} [/tex]
[tex]\qquad\rule{200}2[/tex]
Again , in the second Triangle , we may use ratio of sine to find the value of y , as ;
[tex]\rm\longrightarrow sin45^o =\dfrac{p}{b}\\ [/tex]
[tex]\rm\longrightarrow \dfrac{1}{\sqrt2}=\dfrac{y}{11\sqrt2}\\ [/tex]
[tex]\rm\longrightarrow y =\dfrac{11\sqrt2}{\sqrt2}\\ [/tex]
[tex]\rm\longrightarrow \underline{\underline{ y = 11}} [/tex]
Again , we know that the sides opposite to equal angles are equal . Therefore here ,[tex]\rm\longrightarrow \underline{\underline{ x =11}}[/tex]
