definition of a quadratic function
Answer:
A quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola. Parabolas may open upward or downward and vary in "width" or "steepness", but they all have the same basic "U" shape.

Find the circumference
and area of a circle with
a diameter of 12cm..
Use T = 3.14. Round to
the nearest whole
number.
Answer:
38cm is the circumference
Explanation:
circumference = diameter x 3.14
diameter = 12
circumference = 3.14 x 12 = 37.68
Now we need to round to the nearest whole
36 and 38 are the nearest wholes to 37.68. We need to minus and then find smallest difference between the numbers; meaning the smaller the difference the closer it is.
37.68 - 36 = 0.68
38 - 37.68 = 0.32
37.68 is more closer so we can round this to 38.

Answer:
AC = AB + BC
18 = (2X - 4) + (3X + 2)
18 = 5X - 2 ( add/subtract like terms)
20 = 5X (-2 take over otherside - 18 + 2)
X = 4
SUB X INTO AB AND BC
AB = 2(4) - 4 = 4
BC = 3(4) + 2 = 14

What is the image point of (-8,9)(−8,9) after a translation right 3 units and down 1 unit?
Answer:
(-5,8)
Step-by-step explanation:
The left number represents the x-axis, the right one the y-axis. A translation to the right means in the positive direction on the x-axis, which is why we add 3 to -8 which gives us -5. Down on the y-axis is in the negative direction, which means we have to subtract 1 from 9, giving us 8.
Answer:
the answer is the same since it is the same numeral so in terms of y=mx+c and x1/y1 would be inversely proportional to x2/y2 which is perfectly direct proportional to x3/y3×2 and then dy over dx is the problem of integration so you use (x2/x3÷y2/y3)×x1^y1
What is the value of y in the sequence below?
2,y,18, -54,162,
First, let's check if the sequence is geometric or arithmetric.
If arithmetric, the sequence will have common difference.
Arithmetric
[tex] \displaystyle \large{a_{n + 1} - a_n = d}[/tex]
d stands for a common difference. Common Difference means that sequences must have same difference after subtracting.
Geometric
[tex] \displaystyle \large{ \frac{a_{n + 1}}{a_n} = r}[/tex]
r stands for a common ratio.
To find the value of y, you can check the sequence. If we try subtracting the sequences, the differences are different. That means the sequences are not arithmetric. That only leaves the geometric sequence.
Let's check by dividing sequences.
We have:
2,y,18,-54,162,...Let's check by divide -54 by 18 and 162 by -54. We need to divide more than one so we can prove that the sequence is geometric.
[tex] \displaystyle \large{ \frac{ - 54}{18} = - 3 } \\ \displaystyle \large{ \frac{ 162}{ - 54} = - 3} [/tex]
Hence, the sequence is geometric.
Because the common ratio is -3. Let these be the following:
[tex] \displaystyle \large{ a_{n + 1} = y } \\ \displaystyle \large{ a_n = 2 } \\ \displaystyle \large{ r = - 3 }[/tex]
From the:
[tex] \displaystyle \large{ \frac{a_{n + 1}}{a_n} = r}[/tex]
Substitute the values in.
[tex] \displaystyle \large{ \frac{y}{2} = - 3}[/tex]
Multiply the whole equation by 2 to isolate y.
[tex] \displaystyle \large{ \frac{y}{2} \times 2 = - 3 \times 2} \\ \displaystyle \large{ y = - 6}[/tex]
Therefore, the value of y is -6.
what is (c+d) to the power of 3
Answer:
c³ + cd³ + 3c²d + 3cd²
Step-by-step explanation:
(c+d)^3 is worded as c plus d quantity cubed which doesn't mean you cube everything inside. It means you multiply the quantity by itself 3 times.
(c+d)(c+d)(c+d)
You can only multiply 2 at a time so do the first two then the result and the third one.
Distribute everything in one quantity to the other so c*c = c^2 and c*d = cd
= (c^2 + 2cd + d^2)(c+d)
= c^3 + c^2d + 2c^2d + 2cd^2 + cd^2 + cd^3
Combine like terms
= c³ + 3c²d + 3cd² + cd³
Write 7.12 as a mixed number in simplest form.
Work Shown:
7.12 = 7 + 0.12
7.12 = 7 + (12/100)
7.12 = 7 + (3/25)
7.12 = 7 & 3/25
The notation 7 & 3/25 means we have the whole part 7 and fractional part 3/25.
Aaliyah has a smart phone data plan that costs $45 per month that includes 7 GB of
data, but will charge an extra $30 per GB over the included amount. How much
would Aaliyah have to pay in a month where she used 5 GB over the limit? How much
would Aaliyah have to pay in a month where she used went over by x GB?
The amount that Aaliyah would have to pay in a month where she used 5 GB over the limit is $195.
Cost of data plan per month = $45
Extra amount charged = $30 per GB
The amount that Aaliyah would have to pay in a month where she used 5 GB over the limit will be:
= $45 + $30(5)
= $45 + $150
= $195
The amount that Aaliyah have to pay in a month where she used went over by x GB will be:
= $45 + $30(x)
= $45 + $30x

Here is a data set:
1 2 3 3 4 4 4 4 5 5 6 7
What happens to the mean and standard deviation of the data set when the 7 is changed to a 70?
Your answer:
The mean is 4 because it is in the middle an it is used the most in the data set.
The mean shift to the right side of the data set and the standard deviation is increased.
What is mean?It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.
It is given that:
The data set is:
1 2 3 3 4 4 4 4 5 5 6 7
The mean of the data = ∑x/n
The mean of the data = 4
The standard deviation of the data set = 1.58
If data changed:
1 2 3 3 4 4 4 4 5 5 6 70
The mean of the data = 9.25
The standard deviation of the data set = 18.36
Thus, the mean shift to right side of the data set and the standard deviation is increased.

To find 15, Beau found 32 = 9 and 4 = 16. He said that since 15 is between 9 and 16,15 must be between 3 and 4. He thinks a good estimate for 15 is 3+4 = 3.5. Is Beau's estimate high, low, or correct? Explain.
Answer:
Answer: His estimate was low
Step-by-step explanation:
It's true that √16 is 4 and that √9 is 3
for √15 :
[tex] \sqrt{15} = 3.9[/tex]
It's true that √15 lies between 3 and 4
[tex] \sqrt{15} : 3 < x < 4[/tex]
Estimated answer :
[tex] = 3.5[/tex]
Exact answer :
[tex] = 3.9[/tex]
Therefore, the error:
[tex] \delta x = 3.9 - 3.5 \\ \\ = 0.4[/tex]
Since error is less than 0.5, his estimation was moderate, [ low ]

Zach has the following partial bags of sugar in his pantry; 2 c., 1.5 c., 0.5 c., 3 c., and 1.5 c. If he uses 1 c. of sugar for his baking, how many cups of sugar will he have left?
Answer: 7.5 cups of sugar.
Step-by-step explanation:
Add all of the above:
2+1.5+0.5+3+1.5= 8.5 cups of sugar
Since Zach only needs 1 cup of sugar, subtract 1 from 8.5.
Therefore, your answer is 7.5 cups of sugar.

Christopher's cell phone company
charges a monthly'rate of $56 plus
$0.95 per gigabyte of data used,
and $0.08 per text message sent.
Christopher sent 55 text messages
messages in April and received a bill
for $68.00. How much data did he
use?
Answer:
8 GB
Step-by-step explanation:
Cost = sum of fees 1, 2, and 3
C = 56 + .95g + .08t
so
68 = 56 + .95g + .08(55)
68 = 56 + .95g + .08(55)
68 = 56 + .95g + 4.4
68 - 56 - 4.4 = .95g
7.6 = .95 g
7.6/.95 = g
8 = g
You are installing a fence around your yard. In the figure,
your yard is rectangle ABCD. Each unit in the coordinate
plane represents 10 feet.
a. What is the perimeter of your entire yard
b. You consider only installing a fence around your backyard represented by rectangle ABEF what is the perimeter of your backyard?
c. The cost of fencing is $50 for each 6 foot section how much do you say by only installing a fence in the backyard?
Perimeter of a shape can be determined by the sum of its individual sides. Thus, the answers to the given questions are:
(a) 360 feet
(b) 240 feet
(c) $1000.0
Perimeter can simply be defined as the sum of all sides of a given figure or shape. Thus, the solutions required can be determined as follows:
(a) Side AB = CA = (7 - 1) x 10 feet
= 6 x 10 feet
= 60 feet
Side AD = BC = 13 - 1
= 12 x 10 feet
= 120 feet
The perimeter of the entire yard = 60 + 120 + 60 + 120
= 360
Perimeter of the entire yard = 360 feet
(b) Side AB = EF = 60 feet
Side FA = BE = (7 -1) x 10 feet
= 60 feet
So that,
The perimeter of the backyard = 60 feet x 4
= 240
Perimeter of the backyard = 240 feet
(c) The cost of installing a fence in the entire yard = [tex]\frac{360}{6}[/tex] x $50
= $3000.0
The cost of installing a fence in the back yard = [tex]\frac{240}{6}[/tex] x $50
= $2000.0
The amount saved by only installing a fence in the back yard = $3000.0 - $2000.0
= $1000.0
Thus, the amount saved by only installing a fence in the back yard is $1000.0
