What is a quadratic equation?A quadratic equation is of the form -
y = f(x) = ax² + bx + c
Given is a quadratic equation that can be written as the difference of squares.
A quadratic equation that can be written as the difference of squares is of the form -
(x² - a²)
For the roots, we can write the equation as -
(x² - a²) = 0
x² = a²
x = ± a
Therefore, there are two possible solutions for the quadratic equation that can be written as the difference of squares.

Davis used a drawing and a scale factor of 4 to design his triangular yard. The area of the yard is 400 ft². He wants to find the area of the scale drawing. A smaller triangle has an area of x. A larger triangle has an area of 400 feet squared. Davis knows that the original area times the square of the scale factor will equal the enlarged area. What is the area of the scale drawing? (Scale drawing)(Scale factor)2 = Enlarged Area (x)(4)2 = 400 16x = 400 x =

in a survey, 8 out of 32 students preferred vanilla ice cream if 252 students are surveyed how many should theoretically prefer ice cream
Answer:
63 people
Step-by-step explanation:
Given parameters:
Number of students survey = 32
Number of those that liked ice-cream = 8
Total population size = 252
Unknown:
How many people in the population should prefer ice cream = ?
Solution:
From the survey;
8 out of 32 students prefer ice cream;
8 : 32
1: 4
This shows that 1 out of 4 students will prefer ice cream
NOw to the total population;
If out of 4 students, 1 prefers ice-cream;
Out of 252 students y will prefer ice-cream
Number of students that prefers ice-cream = [tex]\frac{252}{4}[/tex] = 63people

How many gallons of water will be in the fish tank after 3 minutes? how can you explain your answer
The question is incomplete, the complete question is;
If in 0.5 min the tank gets 0.8 gallons of the water then
how many gallons will be in 1 min ?
how many gallons will be in 3 min?
and how long it takes for 40 gallons?
Answer:
1.6 gallons
4.8 gallons
25 mins
Step-by-step explanation:
This question has to do with proportion.
If it takes 0.5 mins for the tank to get 0.8 gallons
in 1 minute the tank will get 0.8 * 1/0.5 = 1.6 gallons
In 3 minutes the tank will get 3 * 1.6 gallons = 4.8 gallons
if it takes 1 min to get 1.6 gallons
it will take x mins to get 40 gallons
x = 1 * 40/1.6 = 25 mins

Helppp asappp pleaseee. What is the slope of a line perpendicular to the line whose equation is
2x – y = -8. Fully reduce your answer.
Answer:
-1/2
Step-by-step explanation:
2x-y=-8 --> y=2x+8 (slope: 2)
to be perpendicular, the product of two slopes should be -1
thus, the slope of a line perpendicular to this one is -1/2

Use linear equation to calculate intercepts.
Answer:
a=8, b=-4
Step-by-step explanation:
set both equal to zero
a: 0 (-1/2)(8)=-4
-1/2y=-4, multiply both sides by the reciprocal of -1/2, which is -2
y=8 when you multiply both sides by -2
b: 4-(0)(0)=-4
when y is 0, the equation become x-0=-4
or x=-4, meaning x must equal -4
Answer:
a is equal to 8
b=-4

What must be a factor of the polynomial function f(x) graphed on the coordinate plane below? On a coordinate plane, a cubic function crosses the x-axis at (negative 6, 0), (negative 3, 0), (0, 0). x – 6 x – 3 x + 1 x + 6
Answer:
D: x+6
Step-by-step explanation:
The factor of the polynomial function f(x) is x + 6
What are factors?The factors of a polynomial are the quotients and the zeros of the polynomial
The points on the polynomial curve are given as:
(-6,0), (-3,0) and (0,0)
So, we have:
x = -6
x = -3
x = 0
Equate the above equations to 0
x + 6 = 0
x + 3 = 0
x = 0
Hence, the factor of the polynomial is x + 6

A square on a coordinate plane has the points A(0, 0), B(0, 5), C(5, 5) and D(5, 0). If Square ABCD is rotated about the origin 180 degrees clockwise to form Square A'B'C'D', what would be the length of one of the sides? A. 0 units B. 5 units C. 10 units D. 20 units
Answer:
B. 5 units
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, dilation, rotation or translation.
If a point X(x,y) is rotated about the origin 180 degrees clockwise the new point is at X'(-x, -y).
If the square with vertices at A(0, 0), B(0, 5), C(5, 5) and D(5, 0) is rotated about the origin 180 degrees clockwise the new points are at A'(0, 0), B'(0, -5), C'(-5, -5), D'(-5, 0)

A.576pi cubic units
B.1,728pi cubic units
C.2,304pi cubic units

Pls help!!
Answer:
C.2,304pi cubic unitsStep-by-step explanation:
Volume of the sphere:
V = 4/3πr³Since d = 24 units,
r = d/2 = 12 unitsThen
V = 4/3π(12³) = 2304πCorrect option is C

Is 25 x 10 to the power of 0 in scientific notation? If not, explain. Use pencil and paper. Explain why 10 is used as the base in the second scientific notation factor.
Answer:
a) Scientific notation is written as a unit digit, that can have other digits after the decimal place, multiplied by 10 to the power of n, where n can be any integer number.
Then 25x10^0 is not scientific notation, because there are two digits at the left of the decimal point.
The scientific notation would be:
2.5x10^1
b) Why is this useful?
Because we divide all our measures in powers of 10.
For example, you know that 1 meter = 100c
But we can also write this as:
1m = 1.0*10^3 cm.
The use of scientific notation comes useful because we can have a fast read of the dimensions of our measure, and in another hand, is way easier work with the 10 as a base when we solve equations.
