Answer:
(3, -2)
Step-by-step explanation:
To find the vertex, put the equation into vertex form by completing the square
2(x^2 - 6x) + 16 [pulling out the 2]
2(x^2 - 6x + 9) - 18 + 16 [completing the square, you subtracted 2*9 = 18 so you also add 18]
2(x - 3)^2 - 2 [simplify the equation]
vertex is (3, -2)

A certain pipe can be used to fill a pool with water in 2 hours. A second pipe can be used to fill the pool in 4 hours. How long does it take to fill the pool when both pipes are used at the same time?
Answer:
1 1/3 hours
Step-by-step explanation:
Pipe 1 alone:
fills the pool in 2 hours
in 1 hour, it fills 1/2 of the pool
Pipe 2 alone:
fills the pool in 4 hours
in 1 hour, it fills 1/4 of the pool
Pipe 1 and Pipe 2 working together:
fill the pool in x hours
in 1 hour, they fill 1/x of the pool
Working together, in 1 hour the two pipes fill 1/2 + 1/4 of the pool.
Working together, in 1 hour the two pipes fill 1/x of the pool.
Therefore,
1/2 + 1/4 = 1/x
2/4 + 1/4 = 1/x
3/4 = 1/x
x = 4/3
x = 1 1/3
Answer: 1 1/3 hours
Write the equation of the line which passes through (1, 2) and with slope of −1/3
in standard form.
Answer:
x + 3y = 7Step-by-step explanation:
The equation of a line which passes through (x₁, y₁) and with slope of m in point-slope form:
y - y₁ = m(x - x₁)
m = -¹/₃
(1, 2) ⇒ x₁ = 1, y₁ = 2
Therefore, the equation of the line which passes through (1, 2) and with slope of −1/3 in point-slope form:
y - 2 = -¹/₃(x - 1)
y - 2 = -¹/₃x + ¹/₃ {add ¹/₃x to both sides}
¹/₃x + y - 2 = ¹/₃ {add 2 to both sides}
¹/₃x + y = 2¹/₃ {multiply both sides by 3}
x + 3y = 7

Given the 3 points A(0;1) , B(5;0) , and C(4;2)
a) Find the coordinates of M the midpoint of [AB]
b) Find the coordinates of G the center of gravity of the triangle ABC .
Answer:
The answer is below
Step-by-step explanation:
a) If O(x, y) is the midpoint between two points X(x₁, y₁) and Y(x₂, y₂)m then the coordinates of O is:
x = (x₁ + x₂)/2; y = (y₁ + y₂) / 2
Since M(x, y) is the midpoint of AB, then the coordinates of M is:
x = (0 + 5) / 2 = 2.5; y = (1 + 0)/2 = 0.5
M = (2.5, 0.5)
b) The center of gravity is gotten by finding the average of the x coordinates and the y coordinates of the vertices of the triangle.
Let O(x, y) be the center of gravity of triangle ABC, hence;
x = (0 + 5 + 4) / 3 = 3
y = (1 + 0 + 2) / 3 = 1
O = (3, 1)

Answer:
L's coordinates would go from being (x,y) to (-x, -y)
Step-by-step explanation:
So like, if L's coordinates were (5, 7) after rotation it would be (-5, -7)
If you were working backward and with L' being rotated you would do (-5, -7) change the sign and do (5,7) for L
Consenquently if you had a negative to begin with- L (-3, -4) L' would be the opposite sign and be (3,4)
Find the surface area of a basketball with a diameter of 10 in.

Step-by-step explanation:
i just took the test :)
The surface area of the ball is 100π square inches. The correct option is C.
How to calculate the surface area of a sphere?The formula for the surface area of a sphere is:
Surface Area = 4πr²
Where r is the radius of the sphere.
Since the basketball has a diameter of 10 in, the radius is half of that, which is 5 in.
Substituting the radius into the formula, we get:
Surface Area = 4π(5²)
Surface Area = 4π(25)
Surface Area = 100π
Therefore, the surface area of the basketball is 100π in².
So the surface area is 100π in².

Explanation of how reflection across axis works?When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.
If study it more, you will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.
Thus, if we are reflecting a point (x,y) along x axis, then its x abscissa will stay same but y ordinates will negate. Thus (x,y) turns to (x, -y)
Similarly, if we are reflecting a point (x,y) along y axis, the resultant image of the point will be (-x,y)
The sides and angles should be the same as the un-reflected version, except everything is flipped, thus the corresponding parts are attached below.

I'd appreciate any help I can get! :) A gold statue has a diameter of 60 inches and a height of 80 inches. It has a total volume of 320 inches cubed. The replica is proportional to the statue. The replica's height is 100 inches. What is the replica's volume?
Answer:
Volume of replica = 625 cubic inches
Step-by-step explanation:
Height of the gold statue = 80 inches
Volume of the gold statue = 320 cubic inches
Height of the replica = 100 inches
Dimensional scale factor = [tex](\frac{\text{Dimension of the replica}}{\text{Dimension of the original statue}})[/tex]
= [tex]\frac{100}{80}[/tex]
= 1.25
Volume scale factor = [tex]\frac{\text{Volume of replica}}{\text{Volume of original}}[/tex]
Since, volume scale factor = (Dimensional scale factor)³
[tex]\frac{\text{Volume of replica}}{\text{Volume of original}}=(1.25)^3[/tex]
Volume of replica = (1.25)³ × Volume of original statue
= (1.25)³ × 320
= 625 cubic inches

The equivalent expressions for [tex]\sqrt{\frac{36a^8}{225a^2} }[/tex] are A, B and E.
What is Square Root?Square root of a number is the value such that the value when multiplied to itself two times gives the original number.
It is denoted by the symbol √.
Given expression is [tex]\sqrt{\frac{36a^8}{225a^2} }[/tex].
There are five expressions in the left.
A. [tex]\sqrt{\frac{2(2)(3)(3)(a)(a)(a)(a)(a)(a)(a)(a)}{3(3)(5)(5)(a)(a)} }[/tex]
Here we have to multiply the terms in the numerator as well as in the denominator.
2(2)(3)(3) = 36 and 3(3)(5)(5) = 225
So this expression is equivalent to the given [tex]\sqrt{\frac{36a^8}{225a^2} }[/tex].
B. [tex]\sqrt{\frac{4a^6}{25} }[/tex]
We know that, greatest common factor of 36 and 225 is 9.
36/9 = 4 and 225 / 9 = 25
Also a⁸ / a² = a⁸⁻² = a⁶
So this is also an equivalent expression.
C. [tex]\frac{6}{25} \sqrt{ \frac{a^8}{a^2} }[/tex]
This is not equivalent since √225 = 15, not 25.
D. [tex]\frac{6}{15} a^4[/tex]
This is also not equivalent since [tex]\sqrt{ \frac{a^8}{a^2} }[/tex] = [tex]\sqrt{a^6}[/tex] = a³, not a⁴.
E. [tex]\frac{2}{5} a^3[/tex]
This is equivalent expression since √36 = 6 and √225 = 15.
[tex]\sqrt{\frac{36a^8}{225a^2} }[/tex] = [tex]\frac{6}{15}[/tex] [tex]\sqrt{ \frac{a^8}{a^2} }[/tex] = [tex]\frac{2}{5}[/tex] [tex]\sqrt{a^6}[/tex] = [tex]\frac{2}{5} a^3[/tex]
Hence the equivalent expressions are A, B and E.

1/2x - 7 = 1/3 (x- 12)
Answer:
x = 18
Step-by-step explanation:
1/2x - 7 = 1/3 (x- 12)
Multiply both sides by 3
3 * 1/2x - 3 * 7 = 3 * 1/3 (x - 12)
3/2x - 21 = x - 12
Collect like terms
3/2x - x = 21 - 12
1/2x = 9
Multiply both sides by 2
x = 2 * 9
x = 18
