The function whose graph matches this one y= 4 sin (π/7 x) - 2
As, The general form of a sine function is
y= A sin (kx) + C........(1)
From the given graph the maximum value of the function is 2 and minimum value of the function is -6.
So, Amplitude= (Max- Min)/2
A = (2- (-6))/2
A= 8/2
Amplitude= 4
Now, The function complete a cycle in 14 units, so period of the function is 14.
2π/k= 14
k = π/7
and, Midline= (Min + Max)/2 = (2-6)/2 = -2
So, the function is
y= A sin (kx) + C.
y= 4 sin (π/7 x) - 2

Answers
For shoveling snow for 6.5 hours, Nina will earn $ 78 and to earn $ 36, Nina need to shovel for 3 hours.
Given that:-
Nina earns $60 for 5 hours of shoveling snow.
We have to find the amount Nina will earn for shoveling snow for 6.5 hours and the number of hours she needs to work for $36.
Amount of money Nina gets per hour = 60/12 = $ 5.
Amount of money Nina gets after working for 6.5 hours = 6.5*12 = $ 78.
Number of hours Nina need to work to earn $ 36 = 36/12 = 3 hours.

When Emily woke up, the temperature was 8°F. By noon, the temperature had risen by 3°F. It rose another 6°F in the afternoon to reach the day’s high temperature. By the time Emily went to bed, the temperature had dropped 21°F from the high temperature. What was the temperature when Emily went to bed?
Answers
Answer:
The temperature when Emily went to bed was -4°F.
Step-by-step explanation:
8°F + 3°F = 11°F (noon)
The temperature had risen by 3°F by noon. This means to add 3.
noon + 6°F = the day's high temperature
11°F + 6°F = 17°F (the day's high temperature)
The temperature rose another 6°F in the afternoon. This means add 6 to the temperature from noon.
high temperature - 21°F = temperature at bed
17°F - 21°F = -4°F
The temperature dropped by 21°F when Emily went to bed. This means to subtract 21 from the day's high temperature.
Risen, rose, and increase mean addition.
Decrease, dropped, and decline mean subtraction.

For the given data, construct a frequency distribution and frequency histogram of the data using five classes. Describe the shape of the histogram as symmetric, uniform, skewed left, or skewed right. Data set: ages of 20 cars randomly selected in a student parking lot 12 6 4 9 11 1 7 8 98 9 13 5 15 7 6 8 8 21 A. skewed right B. uniform C. symmetric D. skewed left
Answers
To construct a frequency distribution and frequency histogram of the data using five classes, we first need to determine the range of the data and the class interval.
The range is the difference between the highest and lowest values in the data set, in this case, 98 - 1 = 97.
We can divide the range by the number of classes to determine the class interval. In this case, 97/5 = 19.4.
We will round up to 20 to have easily divisible numbers.
The class intervals with the frequency would be:
1-20: 3
21-40: 2
41-60: 0
61-80: 3
81-100: 2
Next, we need to create a frequency histogram by plotting the class intervals on the x-axis and the frequencies on the y-axis, and then drawing a bar for each class interval representing the frequency.
The histogram will be skewed right. A histogram is skewed right when the tail of the histogram extends farther to the right than the left. In this case, the majority of the data falls in the lower class intervals, but there are a few outliers on the higher end, which extends the histogram to the right.

The simplified expression for sin²(π/2 - x ) / (csc²x - 1) is cos²x / (cot²x - 1).
What is the simplification of the expression?A simplified version of the expression is determined as follows;
sin²(π/2 - x ) / (csc²x - 1) = cos²x / (cot²x - 1)
We can use trigonometric identities to simplify the expression.
First, we use the identity sin(π/2 - x) = cos(x) to rewrite the numerator as cos²x.
Then, we use the identity csc²x - 1 = cot²x to rewrite the denominator.
Putting these together, we get cos²x / (cot²x - 1) as the simplified expression.

Which expression represents the

produced during the second year?
Answers
The expression that represents the number of reams of paper the company produced during the second year is 4.704 × 10¹⁰. The correct option is D. 4.704 × 10¹⁰
Writing an ExpressionFrom the question, we are to determine the expression that represents the number of reams of paper the company produced during the second year
From the given information,
During the first year of operation,
The company produced 8.4 × 10⁹ reams of paper
And
During the second year,
the company produced 5.6 times the number of reams of paper that it produced during the first year.
Thus,
The number of reams of paper the company produced during the second year = 5.6 × 8.4 × 10⁹ reams of paper
The number of reams of paper the company produced during the second year = 47.04 × 10⁹ reams of paper
= 4.704 × 10¹ × 10⁹ reams of paper
= 4.704 × 10¹⁰ reams of paper
Hence, the expression that represents the number of reams of paper the company produced during the second year is 4.704 × 10¹⁰. The correct option is D. 4.704 × 10¹⁰

The side lengths of a triangle are 5, 8, and 12. Is this a right triangle?
O A. No, because 52 + 32 + 122.
OB. No, because 5+ 8 + 12.
C. Yes, because 52 + 82 = 122.
O D. Yes, because 52 + 82 < 122
Answers
Answer:
A) No...
Step-by-step explanation:
We can check if this triangle is a right triangle by using the Pythagorean Theorem.
a² + b² = c² where a and b are the legs of the right triangle, and c is the hypotenuse (longest side)Using 5 for a, 8 for b, and 12 for c, let's see if this satisfies the equation:
5² + 8² = 12²Simplify.
25 + 64 = 144 89 = 144We can see that 89 ≠ 144, so this leaves us with answer choices A and B. I think you meant to write < for the last + sign.
Seeing as the sum of the two lengths of the triangle is greater than the third side length, this creates a normal triangle. This cannot be the correct answer choice since this only satisfies the requirements for a triangle, but not a right triangle.
This leaves us with answer choice A. 52 + 32 ≠ 122 and 52 + 32 < 122. (I'm not sure why the squares of the side lengths are not used, but this should be the correct answer.)
