Step-by-step explanation:
Quadratic function is in general form of:
y = ax^2 + bx + cThe function has a minimum if a > 0 and maximum if a < 0
The minimum or maximum point is a vertex of the graph
A vertex is the point x = -b/2aWhen b = 0, the min or max point equals to value of c.
33. It has maximum of -134. It has minimum of 735. It has minimum at x = - 8/4 = -2f(-2) = 2*(-2)^2 + 8(-2) + 7 = 8 - 16 + 7 = - 1
36. It has maximum at x = -18/2(-3)= 3g(3) = -3*3^2 + 18*3 - 5 = -27 + 54 - 5 = 22
37. It has minimum at x = - 6/(2*3/2) = - 2f(-2) = 3/2*(-2)^2 + 6(-2) + 4 = - 6 - 12 + 4 = - 14

Step-by-step explanation:
Mr. Wong wants to purchase 12 new smoke detectors for his house. Store A sells each smoke detector for $17 and Store B sells each smoke detector for $24. If Mr. Wong purchases all his smoke detectors at Store A, how much less will he spend than if he purchased all the smoke detectors at Store B?
Answers
Answer:
$84
Step-by-step explanation:
so for store A, you would do $17*12 smoke detectors, Which would give you $204. For store B you would do $24*12 smoke detectors. That is $288. Now all you do is 288-204=84. You would save $84 dollars going to store A
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The amount less spend by buying in store A than in store B is $84
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The number of smoke detectors to be purchased.
= 12
Store A:
Cost of one smoke detector = $17
Cost of 12 smoke detectors.
= 12 x 17
= $204
Store B:
Cost of one smoke detector = $24
Cost of 12 smoke detectors.
= 12 x 24
= $288
Now,
The difference between the cost of 12 smoke detectors from store A to store B.
= $288 - $204
= $84
Thus,
The amount less spend by buying in store A than in store B is $84

Answer:
ans of problem 12 is:
x=65
y=10
Answer:
Step-by-step explanation:
Problem 12:
I think that (2x-y)+60=(2x+y)+40
Because of the Alternate Interior Angles theorem, which places the 40 next to (2x+y) so then you know they are a linear pair. Same can be done for the side with the 60 degree angle. So both sides add up to 180 so they are congruent themselves and you can put them in this format:
(2x-y)+60=(2x+y)+40
-40 -40
We do this to remove the 40 from the right side completely, and whatever you do to one side of the equation you have to do to the other as well so remove 40 from both.
(2x-y)+20=(2x+y)
-2x -2x
Again, we are just trying to find out y right now
-y +20=y
+y +y
20 = 2y
10 = y
Then insert the y into an equation telling us that it is equal to 180 (because we know that from before) to get what x is
(2x-y)+60=180
We can also input our y that we found out was 10 from before:
(2x-10)+60=180
And now we can add up 60 and -10
2x+50=180
Now subtract 50 to both sides
2x=130
And divide both sides by 2
x=75
So x=75 and y=10

A pyramid of logs has 2 logs in the top row, 4 logs in the second row from the top, 6 logs in the third row from the top, and so on, until there are 200 logs in the bottom row. Is the pattern an arithmetic sequence? Identify a and d. Write the 50th term of the sequence. Find the total number of logs in the first 10 rows.
Answers
Answer:
1) Is the pattern an arithmetic sequence?
Yes it is
2)Identify a and d.
a = First term = 2
d = Common difference = 2
3) Write the 50th term of the sequence.
50th term = 100
4) Find the total number of logs in the first 10 rows.
= 1010 logs
Step-by-step explanation:
Is the pattern an arithmetic sequence?
Yes it is
2) Identify a and d.
A pyramid of logs has 2 logs in the top row, 4 logs in the second row from the top, 6 logs in the third row from the top, and so on,
The formula for arithmetic sequence =
an = a+ (n - 1)d
a = First term
d = Common difference
For the above question:
a = 2
d = Second term - First term
= 4 - 2
d = 2
3) Write the 50th term of the sequence.
Using the formula for arithmetic sequence
an = a+ (n - 1)d
a = 2
n = 50
d = 2
a50 = 2 + (50 - 1)2
= 2 + (49)2
= 2 + 98
= 100
The 50th term = 100
4)Find the total number of logs in the first 10 rows.
Sum of first n terms = n/2(a + l)
n = 10
a = first term = 2
We are told that there are 200 logs in the bottom row, hence:
l = last term = 200 logs
Hence,
Sn = 10/2×[ (2 + 200
= 5(202)
= 1010 logs

The function c(x) = 2.5x + 15 shows the cost, in dollars, to make x necklaces.
What is c(10)?
What is c(15)?
What is the best interpretation of c(20) = 65 in terms of the problem?
Answers
Answer:
c(10)=40
c(15)=52.5
Step-by-step explanation:
c(10) means you plug 10 into your x same with (c15) you plug in 15 so for c(10) it would be 2.5(10) + 15 which is 40
The value of c(10) and c(15) is 40 and 65 respectively.
The given function is c(x) = 2.5x + 15.
What is the function?A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.
Now, c(10)=2.5(10)+15=40
c(15)=2.5(15)+15=52.5
Given c(20) = 65
So, 65=2.5x+15
⇒50=2.5x
⇒x=20
Therefore, the value of c(10) and c(15) is 40 and 65 respectively.
