Answer
The answer to the question is 3.157 revolutions per second.
Step-by-step explanation:
The reason is because speed is the distance the object travels in a second.
So, we know that the wind turbine is moving 19 revolutions per minute, so therefore to find the number of rotations the wind turbine is doing per second we have to do 60/19 because there is 60 seconds in a minute.
Therefore, if we do that equation we get the answer, as 3.157 revolutions per second!

Use complete sentences to answer the following question.
1. Choose one of the properties of exponents (for example, the Power of a Power Rule). Explain how the property works, and provide an example of the property.
Answer:
Product of a Power: When you multiply exponentials with the same base, you add their exponents (or powers). Power to a Power: When you have a power to a power, you multiply the exponents (or powers). Quotient of Powers: When you divide exponentials with the same base, you subtract the exponents (or powers).
Step-by-step explanation:
Answer:
What is the Power rule?
The Power rule tells us how to differentiate expressions of the form x^nx
n
x, start superscript, n, end superscript (in other words, expressions with xxx raised to any power):
\dfrac{d}{dx}x^n=n\cdot x^{n-1}
dx
d
x
n
=n⋅x
n−1
start fraction, d, divided by, d, x, end fraction, x, start superscript, n, end superscript, equals, n, dot, x, start superscript, n, minus, 1, end superscript
Basically, you take the power and multiply it by the expression, then you reduce the power by 111.
Example: What is the derivative of x2 ?
For x2 we use the Power Rule with n=2:
The derivative of x2 = 2x(2-1)
= 2x1
= 2x
Answer: the derivative of x2 is 2x

Answer:
C) B>A
Step-by-step explanation:
if it doesn't make sense think of it like the number in between A and B is .5. You can visibly see that A is less than or below .5 and B is above or greater than .5, so B is greater than A.

Use the bag of marbles below to answer questions 5 and 6.
Imagine that you have a bag of marbles with
4 red marbles, 5 blue marbles, 3 pink marbles, and 7 green marbles
5) What is the probability you draw a pink marble?
3/19
6) What is the probability you draw a red or blue marble?*
Answer:
5) 3/19
6)9/19
Step-by-step explanation:
there are 19 marbles altogether
Answer:
It should be 9/19
Step-by-step explanation:
since you have the option to draw a red or blue you add those numbers together. So it's asking what is the probability of drawing either marble.

Which equations best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3)? O y = 2x +4 O 2x +y=24 Ov--x-4 O y = x + 2
Answer:
The equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:
y = -1/2x - 2Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptIn our case, we are given
The slope m = -1/2
Point (2, -3)
now substituting m = -1/2 and (2, -3) in the slope-intercept form of the line equation to determine the y-intercept
[tex]y = mx+b[/tex]
-3 = -1/2(2) + b
-3 = -1 + b
b = -3 + 1
b = -2
now substituting m = -1/2 and b = -2 in the slope-intercept form of the line equation
y = mx + b
y = -1/2x + (-2)
y = -1/2x - 2
Therefore, the equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:
y = -1/2x - 2Solve the system of equations by substitution.
3/8x +1/3y=17/24
x+7y=8
Answer:
x=1, y=1.
Step-by-step explanation:
From the second equation:
x = 8 - 7y, so substituting for x in the first equation:
3/8(8 - 7y) + 1/3y = 17/24
3 - 21/8 y + 1/3y = 17/24
1/3y - 21/8y = 17/24 - 3
Multiply through by 24:
8y - 21*3 y = 17 - 72
8y - 63y = -55
-55y = -55
y = 1.
And substituting for y in the second equation:
x + 7(1) = 8
x = 8 - 7
x = 1.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! plz answer correctly
3(5p - 1) - 4(3p - 7)
Also please explain it as well
Answer:
3p + 25
Step-by-step explanation:
Let's start with the original expression:
3(5p – 1) – 4(3p – 7)
We need to distribute each constant to the binomial they are multiplying, and when we do that, we get:
15p – 3 – 12p + 28
Why did the 28 turn out positive? We multiplied two negative numbers together, –4 and –7 , and multiplying two negatives always gives us a positive product.
Now, let's rewrite the expression to group like terms together:
15p – 3 – 12p + 28 — marked like terms, constants bold, variables underlined
15p – 12p + 28 – 3 — rewrote the expression to group like terms
Finally, we combine each set of like terms together to get our final answer:
3p + 25 — simplifying

Tell whether each function is linear or non-linear. Function A Function B x 0 1 2 3 y 0 1 8 27 y = –x + 5
Answer:
Please check the explanation.
Step-by-step explanation:
The slope-intercept form of the linear function
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptThe graph of y = mx + b is a straight line. Thus, y = mx + b represents a linear function.
Analzing the function y = –x + 5
Given the linear function
y = –x + 5
comparing with the slope-intercept form of linear equation
The slope m = -1
The y-intercept b = 5
Also, the graph of a linear function is a straight line.
Thus,
The function y = –x + 5 represents a linear function.
Analzing the Table Function
x 0 1 2 3
y 0 1 8 27
In order to identify whether the given table represents the linear function or not, we need to make sure the given function has a constant change x and y.
If there is a constant change in x and y, then it would be a linear Function otherwise it would not represent a linear function.
There is a constant change in x values.
i.e.
1 - 0 = 1
2 - 1 = 1
3 - 2 = 1
But, there is NOT a constant change in y.
i.e.
1 - 0 = 0
8 - 1 = 7
27 - 8 = 19
It is clear that the table does not have a constant change in y-values.
Therefore, the table function does not represent the linear function
