Answer:
$6,675
Step-by-step explanation:
Let
x -----> the number of tickets sold
y ----> the amount of money that the band earn
we know that
The linear equation that represent this problem is
y=4.50x+1,500
The greatest amount of money that the band can earn is when the number of tickets sold is equal to the maximum number of seats in the auditorium
so
For x=1,150
substitute
y=4.50(1,150)+1,500=$6,675

find the X-intercept
f(x)=3^(x-1)-2
The answer is:
The function intercepts de x-axis at "x" equal to 1.631.
Why?To find the x-intercept of the function, we need to make f(x) or "y" equal to 0, and then, isolate "x".
So, isolating we have:
[tex]f(x)=3^{(x-1)} -2\\\\0=3^{(x-1)} -2\\\\3^{(x-1)}=2\\\\Log_{3}(3^{(x-1)})=Log_{3}(2)\\\\x-1=0.631\\\\x=0.631+1=1.631[/tex]
Hence, we have that the function intercepts de x-axis at "x" equal to 1.631.

How many different trios could be selected from a chorus of 20 singers? 20! C(20, 3) P(20, 3)
Answer:
C (20, 3) = 1140
Step-by-step explanation:
We are given that there is chorus of 20 singers and we are to find the number of different trios that can be selected from 20 singers.
This is a problem of combinations where the order of trios is not important.
[tex] C ( 2 0 , 3 ) = \frac { ( 2 0 ! ) } { ( ( 2 0 - 3 ) ! 3 ! ) } [/tex]
[tex]C ( 2 0 , 3 ) = \frac { 2 0 ! } { ( 1 7 ! ) ( 3 ! ) } [/tex]
[tex]C ( 2 0 , 3 ) = \frac{( 2 0 \times 1 9 \times 1 8 )}{( 3 \times 2 \times 1 )}[/tex]
C (20, 3) = 1140

what is (24x-35q) (56q+78x)
Answer:
= 1872x^2 - 1960q^2 - 1386xq
Step-by-step explanation:
First you should distribute.
(24x * 56q), (24x * 78x), (-35q * 56q), (-35q * 78x)
=1344xq + 1872x^2 - 1960q^2 - 2730xq
Now you combine like terms.
= 1872x^2 - 1960q^2 - 1386xq
**NOTE that (^2) means "squared"
Since there are no more like terms that is your final answer. I hope this helps love! :)
Without using technology, describe the end behavior of f(x) = -3x^4 + 7x^2 - 12x + 13
A. Down on the left, down on the right
B. Down on the left, up on the right
C. Up on the left, down on the right
D. Up on the left, up on the right
Answer:
A. Down on the left, down on the right
Step-by-step explanation:
Let x be negative infinity
f(-∞) = -3 (-∞)^4+ 7(-∞)^2 - 12(-∞) + 13
f(-∞) = -3 (∞)^4+ 7(∞)^2 + 12(∞) + 13
The term that dominates is ∞^4
That term is negative because of the -3, so it goes down
f(∞) = -3 (∞)^4+ 7(∞)^2 - 12(∞) + 13
f(∞) = -3 (∞)^4+ 7(∞)^2 - 12(∞) + 13
The term that dominates is ∞^4
That term is negative because of the -3, so it goes down
It is down at -∞ and down and +∞
The end behavior of the function is determined by the sign of the leading coefficient and the degree of the highest-powered term. Since the leading coefficient for f(x) = -3x^4 + 7x^2 - 12x + 13 is negative and the degree is even, it results in a down on the left, down on the right end behavior.
Explanation:To determine the end behavior of a polynomial function, like f(x) = -3x^4 + 7x^2 - 12x + 13, you look at the coefficient and degree of the highest-powered term. The highest-powered term in the function is -3x^4.
Since the highest degree of the function is even (4), the arms of the graph will go in the same direction. That direction is determined by the sign of the leading coefficient, which is negative in this case. Therefore, the end behavior of f(x) is: Down on the left, down on the right.
So, the correct answer is Option A.

At this same time in 2010, 78% of people said they went out dancing at least one night a month. Recently, this number has increased by only 2%. What is the recent percentage of people that go out dancing once a month?
The recent percentage of people that go out dancing at least one night a month, considering an initial percentage of 78% in 2010 and a recent increase of 2%, is 80%.
Explanation:The percentage of people who went out dancing at least once a month in 2010 was 78%. If the number has recently increased by 2%, we need to add these two percentages together to find the recent percentage. In mathematics, when an increase is given in percentage, it's added to the original.
So, let's do the calculation:
78% (percentage in 2010) + 2% (recent increase) = 80% (recent percentage).
So, the recent percentage of people who go out dancing at least once a month is 80%.

* Lets explain how to find the product of binomial by trinomial
- If (ax² ± bx ± c) and (dx ± e) are trinomial and binomial, where
a , b , c , d , e are constant, their product is:
# Multiply (ax²) by (dx) ⇒ 1st term in the trinomial and 1st term in the
binomial
# Multiply (ax²) by (e) ⇒ 1st term in the trinomial and 2nd term in
the binomial
# Multiply (bx) by (dx) ⇒ 2nd term the trinomial and 1st term in
the binomial
# Multiply (bx) by (e) ⇒ 2nd term in the trinomial and 2nd term in the binomial
# Multiply (c) by (dx) ⇒ 3rd term in the trinomial and 1st term in
the binomial
# Multiply (c) by (e) ⇒ 3rd term the trinomial and 2nd term in
the binomial
# (ax² ± bx ± c)(dx ± e) = adx³ ± aex² ± bdx² ± bex ± cdx ± ce
- Add the terms aex² and bdx² because they are like terms
- Add the terms bex and cdx because they are like terms
* Now lets solve the problem
∵ The binomial is (x - 3) and the trinomial is (2x² - 5x + 1)
∴ (x)(2x²) = 2x³
∵ (x)(-5x) = -5x²
∵ (x)(1) = x
∵ (-3)(2x²) = -6x²
∵ (-3)(-5x) = 15x
∵ (-3)(1) = -3
∴ (x - 3)(2x² - 5x + 1) = 2x³ + -5x² + x + -6x² + 15x + -3
- Add the like terms
∵ -5x² and -6x² are like term
∴ Their sum is -11x²
∵ x and 15 x are like terms
∴ Their sum = 16x
∴ (x - 3)(2x² - 5x + 1) = 2x³ - 11x² + 16x - 3
* The product is 2x³ - 11x² + 16x - 3

Answer: Hello there!
Well, the square root is the inverse function of the square potential.
This is if you have [tex](\sqrt{x} )^{2} = x[/tex] and [tex]\sqrt{x^{2} } = +-x[/tex]
A interesting part of the square root is that (-4)*(-4) = 16, and 4*4 = 16, so the solutions for [tex]\sqrt{16}[/tex] are -4 and 4. For this is that you see a +- symbol in the second equation.
Now, if you have the number [tex](a*b)^{2}[/tex]
Now, we put this inside a square root: [tex]\sqrt{(a*b)^{2} } = +-a*b[/tex]
So the solutions for the square root of (a*b)^2 are a*b and - a*b.

A cone is placed inside a cylinder. The cone has half the radius of the cylinder, but the height of each figure is the same. The cone is tilted at an angle so its peak touches the edge of the cylinder’s base. What is the volume of the space remaining in the cylinder after the cone is placed inside it?
Answer:
[tex]\frac{11}{12}\pi r^{2}h\ units^{3}[/tex]
Step-by-step explanation:
we know that
Te volume of the cone is equal to
[tex]V=\frac{1}{3}\pi r^{2}h[/tex]
we have
[tex]r=(r/2)\ units[/tex]
substitute
[tex]V=\frac{1}{3}\pi (r/2)^{2}h[/tex]
[tex]V=\frac{1}{12}\pi r^{2}h[/tex]
Te volume of the cylinder is equal to
[tex]V=\pi r^{2}h[/tex]
we know that
To find the volume of the space remaining in the cylinder after the cone is placed inside it, subtract the volume of the cone from the volume of cylinder
so
[tex]\pi r^{2}h-\frac{1}{12}\pi r^{2}h=\frac{11}{12}\pi r^{2}h\ units^{3}[/tex]

9x² = (3x)² → 3x is the first term
49y² = (7y)² → 7y is the second term
Hence
(3x + 7y)² = 9x² + 42xy + 49y²
