9. Write the equation of the parabola in vertex form.
Vertex: (-4, 6); Point: (-2, -2)
Answers
Answer: y = − 2 ( x + 4 ) 2 + 6
Step-by-step explanation:
Find the parabola through ( − 2 , − 2 ) with vertex ( − 4 , 6 ) using the vertex form y = a ( x − h ) 2 + k .
Standard Form: y = − 2 x 2 − 16 x − 26
Vertex Form: y = − 2 ( x + 4 ) 2 + 6

Answer:
x = 1
Step-by-step explanation:
You can work this several ways.
1) Consider the factor that gets you from the y-value of the known pair to the y-value of the unknown pair. Here, that factor is -6/12 = -1/2.
Then the unknown value of x is the known value multiplied by that same factor:
x = (-1/2)(-2)
x = 1
__
2) You can write the equation for a "varies directly" relationship and solve for the constant of proportionality. Then you can use that equation to find the unknown value of x.
y = kx . . . . . . . . . . . . . . y varies directly with x
k = y/x = 12/-2 = -6
Now we know ...
y = -6x
Filling in the new value for y, we have ...
-6 = -6x
1 = x . . . . . . divide by -6
__
3) You can write a proportion. Since we want to find a value for x, it is convenient to put that in the numerator.
-2/12 = x/-6
Multiplying by -6, we get ...
(-6)(-2)/12 = x = 1

What are exponents ?The number of times a number is multiplied by itself is referred to as its exponent. For instance, 2 to the third (written as [tex]2^3[/tex] ) means: 2 x 2 x 2 = 8. 2 x 3 = 6 does not equal [tex]2^3.[/tex] Keep in mind that a number raised to the power of one is itself.Exponentiation is the process of expressing huge numbers in terms of powers.

When we multiply x*y, we are summing x times the same number: y ory times the same number.(x)
In our case, we are summing three times six, so: 6 + 6 + 6 = 18
We could also say we are summing six times three: 3 + 3 + 3 + 3 + 3 + 3 = 18
Nowwe can say that 6 * 3 = 18

Sanju wants to sell his artwork at a local fair. He has created 10 pieces of artwork and has spent $44 in creating them. He wants to make a profit of $300 at the fair. What is the price he needs to sell each piece to make that profit?
Answers
Answer:
30 dollars
Step-by-step explanation:
Sice he has to make a profit of 300 dollars if you divide 100 by to you get 30.If Sanju sells the artwork at 30 dollars he will make 300 dollars
The price Sanju needs to sell each piece to make a profit of $300 overall is $34.4.
What is profit?The profit is the difference between the selling price and the cost price of an item.
The cost of 10 pieces of artwork is,
Cost of producing 1 piece = $44/10 = $4.4
The Profit on 10 pieces of artwork is,
Profit of each piece = $300/10 = $30
The selling price of each piece of artwork is,
Selling price of each piece = Cost of production + Profit
= $30 + $4.4
= $34.4
Hence, the price Sanju needs to sell each piece to make a profit of $300 overall is $34.4.

Answer:
2x+20+3x+40=90
5x+60=90
5x=30
x = 6
2x+20 = 2(6)+20
12+20
=32
3x+40 = 3(6)+40
18+40
=58
Answer:
Here we can first find the value of x simply by using the concept of corresponding angles.
As we know that angle with measurement 2x+20Degree and the right angle below are corresponding as we can consider the line (underlined in red) as a transversal intersecting lines underlined in green. {PLEASE SEE THE ATTACHMENT TO SEE THE HIGHLIGHTED LINES}
So, we get 2x+20 degree = 90 degree.
= 2x+20=90
= 2x=90-20
= 2x=70
= x= 70/2
= x=35 degree.
Now as we know the value of x we can find the other unknown angle by substituting it in the equation for the other angle.
Therefore, 3x+40degree= 3*35+40
105+40
= 145 degrees.

A producer plans an outdoor concert for the weekend. The cost of the concert is $8,000 which includes advertising, security, printing, tickets, etc. The producer plans to profit $15,000 if all goes well. However, it it rains, the concert will be canceled. The chance of rain is 0.3 according to the weather report. Find the producer’s expected profit.
Answers
Answer: $8,100
Step-by-step explanation:
If it does not rain, the producer stands to make a profit of $15,000.
If it rains, the producer will lose the $8,000 they invested.
The chance of rain is 0.3 which means the chance it does not rain is 0.7.
Producer's expected profit is the weighted average of these outcomes;
= (15,000 * 0.7) + ( -8,000 * 0.3)
= 10,500 + ( - 2,400)
= $8,100
