What is the equation of the sinusoid shown in the graph?
A. y=3cos(pi/2x)
B. y=3cos(4x)
C. y=cos(4x)
D. y=3cos(1/4x)
Answers
Answer:
Answer: C
Step-by-step explanation:
The Cosine Function
The graph of a cosine function is a sinusoid that starts at its maximum value of 1 at x=0 and takes x=2π radians to complete a full cycle. The function of the parent cosine function is:
[tex]y=\cos x[/tex]
Both the amplitude A and the angular frequency w of a cosine can be modeled by the function
[tex]y=A\cos(\omega x)[/tex]
The graph of the cosine function shown in the figure has an amplitude of A=3 and it completes a full cycle at x=π/2, thus:
[tex]\frac{\pi}{2}\omega =2\pi[/tex]
Thus:
[tex]\omega = 4[/tex]
Therefore, the equation of the sinusoid is:
[tex]y=3\cos (4x)[/tex]

The function g(x) is g(x) = 4x² after applying the tansformation because the f(x) is the parent function option (A) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
The options are:
A. g(x)=4x²
B. g(x)=16x²
C. g(x)=1/4x²
D. g(x)=(4x)²
It is given that:
f(x) = x²
From the graph as we can see the function f(x) is the parent function and g(x) is transformed function.
The function g(x):
g(x) = ax²
Plug x = 1
g(x) = 4
4 = 1²a
a = 4
g(x) = 4x²
Thus, the function g(x) is g(x) = 4x² after applying the tansformation because the f(x) is the parent function option (A) is correct.

Clare has a recipe for yellow cake she uses 9 1/3 cups of flour to make 4 cakes. Noah will follow the same recipe. He will make c cakes using f cups of flour. What equation would show the relationship between cake and flour?
Answers
Answer:
[tex]c=\frac{3}{7}f[/tex]
Step-by-step explanation:
Clare uses [tex]9\frac{1}{3}[/tex] cups of flour to make 4 cakes.
Noah follows the same recipe so the ratio of the ingredients used will be proportional.
If Noah uses f cups of flour for c cakes,
[tex]\frac{c}{f} =\frac{4}{9\frac{1}{3}}[/tex]
[tex]\frac{c}{f} =\frac{4}{\frac{28}{3}}[/tex]
[tex]\frac{c}{f} =\frac{4\times 3}{28}[/tex]
[tex]c=\frac{3}{7}f[/tex]
Therefore, relation between cake and flour used is,
[tex]c=\frac{3}{7}f[/tex]

Answer:
A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system.

solve for a.
a + (-7) = -17
A. a = -24
B. = -10
C. a = 10
D. a = 24
Answers
Answer:
the answer is A
Step-by-step explanation:
-17 - (-7) = -24
a = -24
Answer:
b) a = -10
Step-by-step explanation:
a + (-7) = -17
simplify
a - 7 = -17
add 7 to both sides of the equation
a - 7 + 7 = -17 + 7
a = -17 + 7
a = -10

Janice rolls a fair number cube sixty times. She rolled the number four 12 times.
What is the experimental probability of rolling the number four?
Answers
Answer:0.5
Step-by-step explanation:
60➗12
Probability of an event is the measure of its chance of occurrence. The experimental probability of Janice rolling the number four is 0.2
What is experimental probability?Experimental probability calculates the probability of some event from the results of experiments.
For an event E, we get the experimental probability of that event
[tex]P_e(E) = \dfrac{\text{Number of times E occurred}}{\text{Number of times experiments was done}}[/tex]
where, [tex]P_e(E)[/tex] is denoting experimental probability of occurrence of E.
For this case, we're specified that:
The event in consideration is "Rolling the number 4"
The times she rolled the number 4 is: 12
She got four 12 times in 60 rolls of the considered cube.
Thus, we have:
E = Rolling the number 4 on the considered cubeNumber of times E occured = 12Number of times experiment was done = 60Thus, we get:
[tex]P_e(E) = \dfrac{\text{Number of times E occurred}}{\text{Number of times experiments was done}} = \dfrac{12}{60} = \dfrac{1}{5} = 0.2[/tex]
Thus, the experimental probability of Janice rolling the number four is 0.2

Which relationships describe the angle pair x° and 157°? Select each correct answer. O complementary angles 1570 O supplementary angles o adjacent angles vertical angles
Answers
Answer:
Supplementary angles and adjacent angle
Step-by-step explanation:
Both angles x° and angle 157° are supplementary ; this is because the sum of both angles should add up to 180°.Looking closely, each both angles will combine to form angle on a Straight line which from angle theorem adds up to 180°.
Also both angles x° and 157° are adjacent angles most simply because they share a common vertex(this can be interpreted as the point of intersection of the two lines which makes up the diagram.)

Select the correct answer. Which number has a terminating decimal expansion? A. 2/7 B.√12 C. 5/8 D. 2/11
Answers
Answer:
Option C is correct option.
Step-by-step explanation:
We need to determine which number has a terminating decimal expansion.
Terminating decimal
A decimal number that contains a finite number of digits after the decimal point is called terminating decimal .
for example 0.123 is terminating decimal as it has finite number of digits after decimal point.
Now, we will look at each option to find the terminating decimal
A. 2/7
Converting in decimal form: 0.28571....
As it doesn't contain finite numbers after decimal point, so 2/7 is not terminating decimal.
B.√12
Converting in decimal form: 3.46410....
As it doesn't contain finite numbers after decimal point, so √12 is not terminating decimal.
C. 5/8
Converting in decimal form: 0.625
As it contain finite numbers after decimal point, so 5/8 is terminating decimal.
D. 2/11
Converting in decimal form: 0.18181....
As it doesn't contain finite numbers after decimal point, so 2/11 is not terminating decimal.
Therefore, Option C is correct option.

The graph of the function y = x shifted 1 unit up and moved 1 unit to the left
so the new function is now y = (x + 1) + 1.
What is a graph?The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.
These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.
By observing the figure we conclude that it shifted 1 unit up and moved 1 unit to the left.
If the original graph was y = x now it is y = (x + 1) + 1.
