The graph shows the prices of different numbers of bushels of corn at a store in the current year. The table shows the prices of different numbers of bushels of corn at the same store in the previous year. A graph shows Number of Bushels on x-axis and Price of Corn in dollars on y-axis. The x-axis scale is shown from 0 to 14 at increments of 2, and the y-axis scale is shown from 0 to 98 at increments of 14. A straight line joins the ordered pairs 2, 14 and 4, 28 and 6, 42 and 8, 56 and 10, 70 and 12, 84.

Can someone tell me how to evaluate quadratic equations easily with steps (40 points)
here's an example ;^;
f(x) = 3(x + 6)2 - 75
Answer:
See below
Step-by-step explanation:
Expansion
[tex]f(x)=3(x+6)^2-75\\\\f(x)=3(x+6)(x+6)-75\\\\f(x)=3(x^2+12x+36)-75\\\\f(x)=3x^2+36x+108-75\\\\f(x)=3x^2+36x+33[/tex] <-- Stop here if this is what you need
Factorization
[tex]f(x)=3(x^2+12x+11)\\\\f(x)=3(x+1)(x+11)[/tex]
We know from vertex form that the vertex of the parabola is [tex](-6,-75)[/tex] and when factored, the zeroes are [tex]x=-1[/tex] and [tex]x=-11[/tex].

The discriminant of the function is 120, and the function has 2 different x-intercepts
How to determine the discriminant?
The function is given as:
f(x) = -7x^2 + 8x + 2
The discriminant (d) is calculated using:
D =b^2 - 4ac
So, we have:
D = 8^2 - 4 * (-7) * 2
Evaluate
D = 120
Because the value of D is greater than 0, then the function has 2 different x-intercepts

Answer: 462 cm^3
Step-by-step explanation:
formula for triangular prisms:
0.5*b*h = V
b or base = 6*6 cm
h or height = 7 cm
7 * 6 * 6 * 0.5 = 126
V or Volume of triangular prism is 126 cm^3.
formula for rectangular prisms:
b * h = V
b or base = 8*6 cm
h or height = 7 cm
8 * 6 * 7 = 336
V or Volume for rectangular prism is 336 cm^3.
Total Volume of Composite Figure = sum of both Volumes
336 + 126 = 462 cm^3.
[tex]v = a \times b \times h \times \frac{1}{2} [/tex]
[tex]v = 6 \times 6 \times 7 \times \frac{1}{2} [/tex]

Which statements describe the figure on the grid if each square has side lengths of 1 cm? Check all that apply. On a coordinate plane, a figure covers 12 full squares and 12 partial squares. The bottom of the figure is diagonal and crosses 6 squares. The perimeter of the figure is 18 cm. The length of the top of the figure is less than 6 cm. The area of the figure is the sum of 12 full squares and 12 partial squares. The area of the figure is greater than 24 square centimeters. The length of the bottom of the figure is greater than 6 cm. The area of the figure is the sum of 6 full squares and 12 partial squares.
The figure on the grid is an illustration of areas and perimeters of a shape
How to determine the true statements?The question is incomplete, as the figure is not given.
So, I will provide a general explanation on how to determine the area and the perimeter of a shape.
The area of a shape is the amount of space on that shape.
Take for instance a square that has a side length 5 units.
The area of the square would be:
Area = 5 * 5 = 25 square units
On the other hand, the perimeter is the sum of the side lengths of the shape.
Using the same square that has a side length 5 units.
The perimeter of the square would be:
Perimeter = 4 * 5 = 20 units

By the angle sum property of a triangle, the value of x would be equal to 9.
What is the angle sum property?The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.
The sum of the triangle of angles is 180.
6x + 56 + 38 + t = 180
t = 180 - 94 - 6x
t = 86 - 6x
By linear pair
10x + 58 + t = 180
10x + 58 + 86 - 6x = 180
4x + 144 = 180
4x = 180 - 144
4x = 36
x = 9

there are 1800 pupils in a school of witch 2/5 are girls. 540 of the pupils do not play sports. Of these pupils who do not play sports, 5/9 are girls. How many boys play sports?
========================================================
Explanation:
There are 1800 students total.
Take 2/5 of this to find the number of girls
(2/5)*1800 = 720 students are girls
Subtract that result from the total to get the number of boys
1800-720 = 1080 students are boys
We'll use this value later, so let A = 1080.
-------------
540 students do not play sports
(5/9)*540 = 300 girls do not play sports.
540-300 = 240 boys do not play sports
Let B = 240
------------
We found that
A = 1080 boys totalB = 240 boys do not play sportsTherefore,
A-B = 1080 - 240 = 840 boys play sports

Suppose y varies directly with x. If y is 8 when x is 12, find y when x is 18.
[tex]\large\textsf{\textbf{Answer\::}}[/tex]
Please consult the "calculations" section of this ans .
[tex]\large\textsf{\textbf{Calculations\::}}[/tex]
If y varies directly with x , the equation looks like this :
y=kx , where k is the constant of proportionality
Plug in the values :
8=k/12
Multiply times 12 on both sides :
96=k
So the constant of proportionality is 96 .
Now solve for y when x is 18 as follows :
y=96/18
y≈5.33

The relations between angles and arcs in this problem set are ...
The sum of central angles in a circle is 360°The measure of an arc is the measure of the central angle it subtendsThe measure of an inscribed angle is half the measure of the arc it subtends__
B.3.no identifier is given
4.Arc DBC is the difference between a full circle (360°) and short arc DC. The measure of short arc DC is marked as 96°, so ...
arc DBC = 360° -96° = 264°
5.Αrc BC is twice the measure of the inscribed angle BDC it subtends.
arc BC = 2×60° = 120°
6.Arc AB is the difference between 360° and the sum of arcs AD, DC, and CB.
arc AB = 360° -(90° +96° +120°) = 54°
7.Angle ACD is half the measure of arc AD.
Angle ACD = 90°/2 = 45°
8.Angle ADC is half the measure of arc AC, which is the sum of arcs AB and BC
angle ADC = (54° +120°)/2 = 87°
9.Angle ACB is half the measure of arc AB
angle ACB = 54°/2 = 27°
__
C.9.x° is the arc whose central angle is 200°
x° = 200°
y° is half the measure of x°
y° = 200°/2 = 100°
10.The relations between arcs and inscribed angles mean that opposite angles in an inscribed quadrilateral are supplementary.
x° = 180° -112° = 68°
y° = 180° -81° = 99°

What is Arithmetic mean?Arithmetic mean is simply the average of a given set numbers. It is determined by dividing the sum of a given set number by their number of appearance.
Mean = Sum total of the number ÷ n
Where n is number of numbers
Given the sets;
48, 12, 11, 45, 48, 48, 43, 32n = 8First, we arrange in ascending order.
11, 12, 32, 43, 45, 48, 48, 48
Mode
Mode is the number with the highest appearance
Number with highest appearance or frequency is 48 ( 3 appearance )
Mode = 48
Median
Middle numbers fall between 43 and 45
Median = ( 43 + 48 ) / 2
Median = 88 / 2
Median = 44
Mean
We add the numbers
11 + 12 + 32 + 43 + 45 + 48 + 48 + 48 = 287
Mean = Sum total of the number ÷ n
Mean = 287 / 8
Mean = 35.875
