similarities and differences between sine and cosine graphs — Algebra 2
The similarities between sine and cosine graphs are their amplitude and periodicity, while the differences are their starting positions and phase. Overall, the graphs are more similar than different.
Similarities:
The sine and cosine functions have the same amplitude, which is the maximum value of the wave.
Both functions are periodic, meaning they repeat their pattern infinitely.
Differences:
The sine function starts with an amplitude of zero, while the cosine function starts with an amplitude of one.
The sine and cosine functions are out of phase by 90 degrees, meaning they reach their maximum and minimum values at different times.
Overall, the graphs of the sine and cosine functions are more similar than different because they share the same amplitude and shape, but they differ in their starting positions and phase.
Complete Question:
Write the similarities and differences between sine and cosine graphs.
Raquel and Van live in two different cities. As a part of a project, they each record the lowest prices for a gallon of gas at gas stations around their cities on the same day. Raquel’s data show mean = 3.42 and standard deviation = 0.07. Van’s data show mean = 3.78 and standard deviation = 0.23.
Which statement is true about their gas-price data?
A: Raquel’s data are more likely closer to $3.42 than Van’s data are to $3.78.
B: Van’s data are more likely closer to $3.42 than Raquel’s are to $3.78.
C: Raquel’s data are more likely closer to $3.78 than Van’s data are to $3.42.
D: Van’s data are more likely closer to $3.78 than Raquel’s are to $3.42.
Answer:
A: Raquel’s data are more likely closer to $3.42 than Van’s data are to $3.78
Step-by-step explanation:
Given that Raquel’s standard deviation is less than Van's standard deviation, then Raquel’s data are more likely closer to Raquel’s mean than Van’s data are to Van's mean.
Answer:
A
Step-by-step explanation:
Raquel’s data are most likely closer to $3.42 than Van’s data are to $3.78.
What is the measure of Angle c? 3 lines intersect to form 6 angles. Clockwise, from top left, the angles are: C, 48 degrees, 42 degrees, 90 degrees, 48 degrees, 42 degrees. 42° 48° 90° 180°
Answer:
90 so c
Step-by-step explanation:
The measure of Angle c when 3 lines intersect to form 6 angles is 90 degrees.
What is the sum of all the exterior angles of a regular polygon?For a regular polygon of any number of sides, the sum of its exterior angle is 360° (full angle).
Exterior angle is an measure of rotation between one extended side(we extend it virtually) of the polygon with its adjacent side which is not extended.Consider that it be having 'n' sides, all the exterior angles are of same measure, and therefore, their measure is (360/n)°.
We are given that;
The 3 lines intersect and form 6 angles.
Now,
To find angle c, we need to use the fact that the angles around a point add up to 360 degrees. The six angles formed by the three intersecting lines include all the angles around a point, so we have to set up another equation;
Angle c + 48 degrees + 42 degrees + 90 degrees + 48 degrees + 42 degrees = 360 degrees
Simplifying and solving for angle c, we get:
Angle c = 360 degrees - 270 degrees
Angle c = 90 degrees
Therefore, by interior and exterior angles the measure of angle c is 90 degrees.

Final answer:
To solve the equation 4 = 12x - 2, we need to find the value of x. The value that satisfies the equation is x = 1/2.
Explanation:
To find the value of x that makes the equation 4 = 12x - 2 true, we need to solve for x.
12x - 2 = 4
12x = 6
x = 6/12
x = 1/2
So, the value of x that satisfies the equation is x = 1/2.

A farmer has a square lot that is 200 feet on each side. She has a very powerful sprinkler that sprays water in a circle she doesn’t want to waste any water, so she’ll set her sprinkler so that it doesn’t spray any water outside of her lot. What is the largest percentage of her lot that she can water? (Answer to the nearest percent)
Answer:
78.5%
Step-by-step explanation:
Area of a 100ft radius circle = 628sqm
Area of rectangle = 800sqm
= 172sqm difference in size
if 800 sqm = 100%
Then 600 sqm = 3/4 = 75%
60sqm =3/40 = 7.5%
6sq m =3/400 =0.75%
2 sq m = 0.25%
30sqm = 1/2 of 7.5%= 3.75
3.75-0.25 = 3.50%
3.50% + 75 = 78.5%
A circular sidewalk with a radius of 100 meters is having a railing installed
along 120° of its arc. How many meters of railing will be needed? (HINT: arc
length).
A. 100pi/3 m
B. 200pi/3 m
C. 10pi/3 m
D. 2pi/3 m
Answer:
B
Step-by-step explanation:
Whole circle is 360 degrees.
The railing is 120 degrees.
That is:
120/360 = 1/3 rd of the whole length of the circle (perimeter).
We will find perimeter of the circle (a.k.a. Circumference) and then multiply it by (1/3) to get meters of railing needed.
First, circumference:
[tex]C=2\pi r\\C=2 \pi (100)\\C=200\pi\\C=628.32[/tex]
The railing is (1/3)rd of it, so:
[tex]\frac{1}{3}*628.32=209.44[/tex]
The railing is 209.44 meters.
The answer choices are in pi, so it will be:
[tex]\frac{1}{3}*200\pi=\frac{200\pi}{3}[/tex] meters

what is 8 to the power of 3
Answer:
512
Step-by-step explanation:
8×8×8
=512
8³=512
Therefore 8 to the power of 3 is 512
Answer: 512
Step-by-step explanation: 8 to the power of 3 means the same as 8³.
The smaller 3 which is called the exponent tells us that we need to multiply the 8 three times. So we have 8 · 8 · 8 which simplifies to 512.
So 8³ is equal to 512.

Squaring a number and adding one will always produce an even number.
Answer:
False. Squaring any rational, whole number, will always give you a even number. So if you add one to the number, you will get a odd number.
The statement is false.
What is square?When an integer is multiplied by itself, the resultant number is known as its square number. Basically, a square number is a number that is obtained by the product of two same numbers. In geometry, the area of a square with 'n' as the side length (where n is an integer) is the finest example of a square number.

f(x)=x^2+10 What is the average rate of change of F over the interval [-2,-1]
Answer: -3
Step-by-step explanation: plug -2 into f(x)=x^2+10 and you get 14, then plug the -1 into that same equation and end up with 11, now you subtract the 11 from the 14 and get 3 but since you subtracted or in other words the number decreased it would be -3
The average rate of change of f(x) over the interval [-2,-1] is 3.
Explanation:To find the average rate of change of f(x) over the interval [-2,-1], we need to calculate the difference in the function values at the endpoints and divide it by the difference in the x-values. Let's substitute the endpoints into the function:
f(-2) = (-2)² + 10 = 4 + 10 = 14
f(-1) = (-1)² + 10 = 1 + 10 = 11
The difference in function values is 14 - 11 = 3, and the difference in x-values is -1 - (-2) = -1 + 2 = 1. Therefore, the average rate of change is 3/1 = 3.
