What is quadratic equation?A quadratic equation is x ax2+bx+c=0, which is a quadratic polynomial in a single variable. a 0. The Fundamental Theorem of Algebra ensures that it has at least one solution since this polynomial is of second order. Solutions may be simple or complicated. An equation that is quadratic is a quadratic equation. This indicates that it has at least one word that has to be squared. The formula "ax2 + bx + c = 0" is one of the often used solutions for quadratic equations. where are numerical coefficients or constants a, b, and c. where the variable "X" is unidentified.

The table shows the participation in a school’s debate club during the last four years. Year 1 2 3 4 Students 14 19 25 33 Between which two years did the club see the greatest growth? By what percent did it grow? Round to the nearest percent. Use the drop-down menus to show and explain your answer. The greatest growth was between years Choose... and Choose... . The growth between those years was about Choose... .
Answer:
Year 1 and 2
36%
Step-by-step explanation:
Given the data :
Year ______1 ___ 2 ____ 3 ___ 4
Students __ 14 __ 19 ___ 25 __ 33
Greatest growth is observed between year 1 and 2
Growth percent :
(year 2 - year 1) / year 1 * 100%
(19 - 14) / 14 * 100%
5 / 14 * 100%
0.3571 * 100%
= 35. 71%
= 36%
The growth percent between year 1 and 2 is greater than between the other years
Year 2 and 3 = (6/19) * 100% = 31.57%
Year 3 and 4 = (8/25) * 100% = 32%
Answer:
1 and 2 x=32%
Step-by-step explanation:
1. 5/14=x/100
2. 500/14=14x/14
so you get 36%

4. Find the area of the
shaded region.
Diameter of the circle in the middle = 8 ft
Radius of the circle in the middle :
[tex] =\tt \: \frac{Diameter }{2} [/tex]
[tex] =\tt \frac{8}{2} [/tex]
[tex] =\tt 4 \: ft[/tex]
Thus, the radius of the circle in the middle = 4 ft
Area of the entire circle :
[tex] =\tt \pi {r}^{2} [/tex]
[tex] = \tt3.14 \times 4 + 6 \times 4 + 6[/tex]
[tex] = \tt3.14 \times 10 \times 10[/tex]
[tex] =\tt 3.14 \times 100[/tex]
[tex]\color{plum} = \tt314 \: ft[/tex]
Thus, the area of the entire circle = 314 ft
Area of the circle in the middle :
[tex] =\tt \pi {r}^{2} [/tex]
[tex] =\tt 3.14 \times 4 \times 4[/tex]
[tex] = \tt3.14 \times 16[/tex]
[tex]\color{plum} =\tt 50.24 \: ft[/tex]
Thus, the area of the circle in the middle = 50.24 ft
Area of the shaded portion :
= Total area of the figure - Area of the circle in middle
[tex] =\tt 314 - 50.24[/tex]
[tex]\color{plum} =\tt 263.76 \: ft[/tex]
▪︎Therefore, the area of the shaded portion = 263.76 ft

Ben is standing 8 feet from
the base of a telephone pole.
The angle of elevation from the
point on the ground where he is
standing to the top of the pole
is 62°. Find the height of the
telephone pole. Round to
the nearest tenth.
Answer:
Approximately 15.05 ft
Step-by-step explanation:
You need to use tangent for this question.
Since tan θ = [tex]\frac{Opposite}{Adjacent}[/tex]
to find the Opposite, we need to rearrange the equation to:
Adjacent × tan θ = Opposite.
So if you insert 62 for θ and 8 feet for Adjacent, you will get:
8 × tan(62) = Opposite.
and you will get approximately 15.05 feet for your Opposite side

Answer:
16.
Step-by-step explanation:
What does 75% Off mean? It means 75% of the price is subtracted. So find 75% of 64.
Here is our equation: 75/100 x 64 = 48.
So 48 dollars is going to be subtracted from 64, which gives us 64-48=16.
So the price of the wedding cake during the sale is 16.

Noah and Lin are making paper cones to hold popcorn to hand out at parent math night. They want the cones to hold 97 cubic inches of popcorn. What are two different possible values for height h and radius r for the cones?
Answer:
[tex]r = 5[/tex] --- Radius
[tex]h = 3.9[/tex] --- Height
Step-by-step explanation:
Given
Shape: Cone
[tex]Volume = 97in^3[/tex]
Required
Determine different possible values of radius and height
The volume (V) of a cone is calculated as:
[tex]V = \frac{1}{3}\pi r^2h[/tex]
Substitute 97 for V
[tex]97 = \frac{1}{3}\pi r^2h[/tex]
Multiply both sides by 3
[tex]3 * 97 = \frac{1}{3}\pi r^2h*3[/tex]
[tex]291 = \pi r^2h[/tex]
Take [tex]\pi[/tex] as 3.14
[tex]291 = 3.14* r^2h[/tex]
Divide both sides by 3.14
[tex]\frac{291}{3.14} = \frac{3.14* r^2h}{3.14}[/tex]
[tex]\frac{291}{3.14} = r^2h[/tex]
[tex]92.68 = r^2h[/tex]
From the question, we understand that:
[tex]r \ne h[/tex]
So, we have to assume a value for either r or h and then solve for the other variable.
Let [tex]r = 5[/tex]
So, We have:
[tex]96.28 = 5^2 * h[/tex]
[tex]96.28 = 25 * h[/tex]
Make h the subject
[tex]h = \frac{96.28}{25}[/tex]
[tex]h = 3.8512[/tex]
[tex]h = 3.9[/tex] --- approximated
Note that there are other different possible values of h that is true for
[tex]92.68 = r^2h[/tex] where [tex]r \ne h[/tex]

A teacher can grade 10.5 tests every 30 minutes. How many tests can they grade in two 45 minute prep periods?
Answer:
31 tests.
Step-by-step explanation:
The rate for the grading is 10.5 every 30 minutes.
Two 45 minute prep periods are 90 minutes.
90 / 30 = 3.
Since three 30 minute periods fit into 90 minutes, we get
3 x 10.5 = 31.5 tests.
Since a teacher did not finish grading the .5 of the test, we don't count it.
Our answer is 31 tests.
