Write the quadratic function in standard form.
f(x) = (x + 14)2
Answer:
Step-by-step explanation:
It's essential that you use the symbol " ^ " to indicate exponentiation.
Expanding f(x) = (x + 14)^2 results in x^2 + 28x + 196 (which is in standard form)

The scale of a square map indicates that each inch on the map
corresponds to 5 miles. Write an expression that describes the area of
land shown on the map. If the map is 8 inches on one side, what is the
area of land shown on the map?
Answer:
Area of land: 800 miles.
Step-by-step explanation:
Since the map is a square, you can assume that all 4 sides will equal 8 inches. (Giving you a perimeter of 32, and an area of 64.) Since each inch corresponds to 5 miles, you multiply 8 by 5 which equals 40.
What value(s) of z makes the equation 7/6 Z + 1/3 = -5 / 6 true; Z = -1, Z= 2, Z= 1, or Z= -36 / 63?
Answer:
Z = -1
Step-by-step explanation:
to find which value of Z makes the equation true substitute each value of Z into the equation.
Z = -1
7/6(-1) + 1/3 = -5/6
-5/6=-5/6
all other values of Z will not give u an equal statement

Lazare is dividing 52.8 ounces of cereal equally into 9 bags. Which is the best way to estimate the amount of cereal in each bag?
If I'm not mistaken it's 5.9
Estimate amount of cereal in one bag is 5.867 ounces.
What are mathematical operations?Calculate the answer using a math operator is referred to as a mathematical operation.
Basic mathematical operations are addition, multiplication, subtraction and division.
Total quantity of cereal that Lazare has = 52.8 ounces.
And number of bags into which cereal equally divides = 9
To find the amount of cereal in each bag,
Use mathematical operations,
Since, total bags are 9 and amount of cereal is 52.8 ounces.
So, in one bag amount of cereal = 52.8 / 9 = 5.8666 = 5.867
In one bag there will be 5.867 ounces of cereal.

The side length of the base of a square pyramid is 30 centimeters. The height of the pyramid is 45 centimeters.
What is the volume of the pyramid in cubic centimeters?
Answer:
volume = 13500 [tex]cm^{3}[/tex]
Step-by-step explanation:
For a given pyramid, its volume can be determined by:
volume of pyramid = [tex]\frac{lwh}{3}[/tex]
Where: l is the base length, w is the base width and h id the height of the pyramid.
For the given question, l 30 cm, w = 30 cm and h = 45 cm.
So that,
volume = [tex]\frac{30*30*45}{3}[/tex]
= [tex]\frac{40500}{3}[/tex]
= 13500
volume = 13500 [tex]cm^{3}[/tex]
The volume of the pyramid is 13500 [tex]cm^{3}[/tex].
The volume of the square-based pyramid is [tex]13500cm^3[/tex]
The volume of a pyramid is given by
[tex]V=\dfrac{Ah}{3}[/tex]
where
[tex]A=\text{area of the square base}\\h=\text{perpendicular height}[/tex]
The area of the square base, [tex]A[/tex], is calculated as follows
[tex]A=side^2\\=(30cm)^2\\=900cm^2[/tex]
substitute the value of [tex]A[/tex], and [tex]h[/tex] ([tex]45cm[/tex]) into the volume formula to calculate the pyramid's volume
[tex]V=\dfrac{Ah}{3}\\\\=\dfrac{900\times 45}{3}\\\\=13500cm^3[/tex]
Therefore, the volume of the pyramid is [tex]13500cm^3[/tex]

3x + x - 7 = 10
What does x=
First you add 3x+x because they are like terms.
3x+x-7=10
Your New Simplified Equation:
4x-7=10
Now, you have to take out the -7 by adding a positive 7. Also you have to add +7 on the other side so add 7 to 10.
Your New Simplified Equation:
4x=17 Now, you divide both sides by 4.
Your New Simplified Equation:
x= 17/4 So, that's your answer :)

(c) y = 2x-1 and y = 2x-1
Step-by-step explanation:
A system of equations in which both equations describe the same line will have infinitely many solutions (all points on that line).
The same line is (obviously) described by the (identical) equations ...

A first number is four more than seven time a second. The sum of the number is 92. Find the number.
Answer:
11
81
Step-by-step explanation:
x = 7y + 4
x + y = 92
Solve for x in the second equation
x = 92 - y
92 - y = x
Equate the 2 xs
92 - y = 7y + 4 Add y to both sides
92 = 7y+y + 4 Combine
92 = 8y + 4 Subtract 4 from both sides
88 = 8y Divide by 8
88/8 = y
y = 11
===========
x = 7y + 4
x = 77 +4
x = 81
When the outlier(s) are removed, how does the mean change? dot plot with 1 dot over 15, 1 dot over 23, 1 dot over 24, 1 dot over 25, 1 dot over 26, 1 dot over 27, and 1 dot over 35
The mean doesn't change.
The mean increases by 2.
The mean decreases by 2.
There are no outliers.
Answer:
So the answer is A-The mean doesn't change
Step-by-step explanation:
With the outliers the mean is 25, how?
well if we put down the numbers 15,23,24,25,26,27,35 and add them together 15+23+24+25+26+27+35 we get 175 now we have to divide by how many numbers are there 175/7=25. That is the mean WITH the outliers.
Now, WITHOUT the outliers. The outliers are 15 and 35. We know this because, there is a huge gap between 15 and 23, and 27 and 35. We basically do the same thing but without the outliers. 23+24+25+26+27=125 we divide by how many numbers are there 125/5 then we get 25.
Hey love! <3
Answer:
The correct answer is A. The mean doesn't change
Step-by-step explanation:
Since this is a dot plot, first we have to count up the total x-axis amount from the dot plots, then divide it by the numeral amounts (y-axis), then repeat this after removing the outlier from the dot plot.
Thus, the mean remaining the same.
