Answers
The number of books that each shelf hold will be 326 per shelf.
How many books can each shelf hold?From the information, the first bookshelf in the fantasy section of a library can hold 1,635 books, the bookshelf has 5 shelves and each shelf can hold the same number of books.
Let the number of books in each shelf be x.
Therefore, the equation will be:
(5 × x) = 1635
5x = 1635
Divide
x = 1635 / 5
x = 327
The number of books is 327.

Step-by-step explanation:
The zero of this function is 3 . What do you think "zero of a function" means?
Answers
The zeros of a function are the values of x that, when evaluated in the function, make the output of the function to be zero.
What doe the "zero of a function" means?A function is written in general form as y = f(x)
That notation says that, when we use the input "x" in a given function, that function "transforms" that input x into an output "y"
So y = f(x) is the value that the function takes for the input x.
A zero is an input of the function such that:
0 = f(x)
So the zeros are the inputs that have an output of zero, in this case you know that the function has a zero at 3, and as you can see, when x = 3, the function intercepts the x-axis, which is the axis defined by y = 0.

Step-by-step explanation:
let's simply do the multiplications and then compare with the original.
(x-m)² + n
right ?
or is it
\( {(x - m)}^{2 + n} \)
let's go for the first.
x² - 2mx + m² + n = x² - 3x
-2mx + m² + n = -3x
fun there we see two things :
-2m = -3
m = 3/2

m² + n = 0
(3/2)² = -n

y = -10 (False).
When the value of x = 0 in table H, the linear function is given by;
y = x - 12

y = -10 (True).
When the value of x = 4 in table H, the linear function is given by;
y = x - 12

How to define a linear function?The slope-intercept equation for a linear function is presented as follows:

m = 1/1 = 1.
Hence:
P(h) = h + b.
When h = 4, P(h) = 15, hence the intercept b is given as follows:
15 = 4 + b
b = 11.
Hence the rule is:
P(h) = h + 11.

The unit rate of the relationship will be 10/3. The correct option is C.
The given equation is,
y = 10/3x + 8
The general form of an equation of the line is,
y = mx + c
here, the slope will be 10/3
Slope refers to the steepness or incline of a line on a graph. It is a measure of how much the dependent variable changes for a given change in the independent variable.
The slope of a line is represented by the ratio of the change in the y-axis (vertical) to the change in the x-axis (horizontal) between any two points on the line. It can also be interpreted as the rate of change of the dependent variable with respect to the independent variable.
A positive slope indicates an upward trend, while a negative slope indicates a downward trend. The slope of a line is often denoted by the letter m.
The unit relationship will be 10/3.

What two numbers add to 7 and multiply to -44
Answers
Answer:
The numbers are 11 and -4
Step-by-step explanation:
Given
Let the two numbers be \(x\) and \(y\)
such that:
\(x + y = 7\)
\(x*y = -44\)
Required
Find x and y
Make y the subject in: \(x + y = 7\)
\(y = 7 - x\)
Substitute \(y = 7 - x\) in \(x*y = -44\)
\(x(7-x) = -44\)
Open bracket
\(-x^2 +7x = -44\)
Rewrite as:
\(x^2 -7x -44=0\)
Expand
\(x^2 +4x-11x -44=0\)
Factorize
\(x(x +4)-11(x +4)=0\)
Factor out x + 4
\((x -11)(x +4)=0\)
Solve for x
\(x =11; x =-4\)
Recall that:
\(y = 7 - x\)
So:
\(y = 7-11 = -4\)
or
\(y = 7--4 = 11\)

d. If you got your 60% discount and opened up the card for an additional 20%, what is the actual % discount you would receive?
Answers
Answer:
The actual discount is a 68% discount.
Step-by-step explanation:
Remember that if something has a price P, and you have a discount of the X%, the new price will be:
P' = P - P*(X%/100%) = P*(1 - X%/100%)
Here we first have a 60% discount, then if the initial price is P, the new price is:
P' = P*(1 - 60%/100%) = P*(1 - 0.6)
Now we have an additional 20% discount (this applies to the new price)
then the final price is:
P'' = P'*(1 - 20%/100%) = P'*(1 - 0.2) = P*(1 - 0.6)*(1 - 0.2)
We want to rewrite this as something like:
P'' = P*(1 - k)
Let's do this:
P'' = P*(1 - 0.6)*(1 - 0.2) = P*(1 - 0.2 - 0.6 + 0.2*0.6)
= P*(1 - 0.8 + 0.12) = P*(1 - 0.68)
And this can be as:
P'' = P*(1 - 68%/100%)
Then the actual discount is a 68% discount.

Step-by-step explanation:
I am using (xy) to mean the length of the side xy
7^2 + (xy)^2 = 15^2
49 + (xy)^2 = 225
(xy)^2 = 225-49
(xy)^2 = 176
Side (xy) = sqrt(176) = 13.2664991614 = 13.27 cm
13.3cm
Step-by-step explanation:
The Pythagorean theorem is a^2+ b^2 = c^2
Plug the values into the equation.
7^2+ b^2 = 15^2
Simplify.
49 ÷ b^2 = 225
Subtract 49 from both sides.
b^2 = 176
Take the square root of both sides.
vb^2 = v176

Answers
The length of the arc defined by the central angle of 312 degrees is 26π cm.
The formula for the arc length of a circle is given by:
L = (θ/360) × 2πr
where L is the length of the arc, θ is the central angle in degrees, and r is the radius of the circle.
Substituting the given values, we get:
L = (312/360) × 2π(30)
L = (26/30) × π × 30
L = 26π cm
Therefore, the length of the arc defined by the central angle of 312 degrees is 26π cm.
