Answer A: 84π
Answer B: I'm also confused. If anyone else knows can you please help me also. Sorry for not answering B. I hope this helps though.
Step-by-step explanation:
Answer A:
V=1/3π 6^2 (7) Since 12 is a diameter you half it which is 6
V=1/3π 36(7)
V=1/3π 252
V= 252π/3
V=84π
What is the image of (- 4, 3) after a dilation by a scale factor of 2 centered at the origin?
Answer: (-8,6)
Step-by-step explanation:
Question: What is the image of (-4,3)(−4,3) after a dilation by a scale factor of 22 centered at the origin?
Dilation: multiply each coordinate
(x,y)\rightarrow (2x,2y)
(x,y)→(2x,2y)
Dilations multiply by scale factor
(\color{red}{-4},\color{blue}{3}) \rightarrow (2\cdot \color{red}{-4},2\cdot \color{blue}{3})=\mathbf{(-8,6)}
(−4,3)→(2⋅−4,2⋅3)=(−8,6)
This was on my delta math so i hope this helps
The image of the point (- 4, 3) after dilation will be (-8,6).
What is dilation?Dilation is the process of increasing the size of an object while maintaining its shape. Depending on the scale factor, the object's size can be increased or decreased.
The scale factor is defined as the proportion of the new image's size to that of the previous image. decision-making.
Given point is (-4, 3). The dilation of the point will be calculated as below:-
Dilation:- multiply each coordinate.
(x,y)→(2x,2y)
Dilations multiply by a scale factor
(−4,3)→(2⋅−4,2⋅3)=(−8,6)
Therefore, the image of the point (- 4, 3) after dilation will be (-8,6).

If y varies directly as x and x=6 when y=0.5, find y when x=10
Answer:
y = [tex]\frac{5}{6}[/tex]
Step-by-step explanation:
Given y varies directly as x, then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 6 when y = 0.5 , then
0.5 = 6k ( divide both sides by 6 )
[tex]\frac{0.5}{6}[/tex] = k , that is k = [tex]\frac{1}{12}[/tex]
y = [tex]\frac{1}{12}[/tex] x ← equation of variation
When x = 10, then
y = [tex]\frac{1}{12}[/tex] × 10 = [tex]\frac{10}{12}[/tex] = [tex]\frac{5}{6}[/tex]
PLZ HELP -geometry- Find the coordinates of the intersection of the diagonals of parallelogram GHJK with vertices G(1,3), H(4,3), J(5,1), and K(2,1).
The coordinates are ( , ).
Answer:
The coordinates of the intersection of the diagonal of the parallelogram are [tex]M(x,y) = (3,2)[/tex].
Step-by-step explanation:
Diagonals are represented by line segments GJ and KH. Since quadrilateral is a parallelogram, then coordinates of the intersection are located at midpoint of each diagonal ([tex]M(x,y)[/tex]). That is:
[tex]M(x,y) = G(x,y) + \frac{1}{2}\cdot \overrightarrow {GJ}[/tex]
[tex]M(x,y) = G(x,y) +\frac{1}{2}\cdot [J(x,y)-G(x,y)][/tex] (1)
If we know that [tex]G(x,y) = (1,3)[/tex] and [tex]J(x,y) = (5,1)[/tex], the coordinates of the intersection of the diagonals of the parallelogram are:
[tex]M(x,y) = (1,3) +\frac{1}{2}\cdot [(5,1)-(1,3)][/tex]
[tex]M(x,y) = (1,3) +\frac{1}{2}\cdot (4,-2)[/tex]
[tex]M(x,y) = (1,3) +(2,-1)[/tex]
[tex]M(x,y) = (3,2)[/tex]
There is another form:
[tex]M(x,y) = K(x,y) +\frac{1}{2}\cdot \overrightarrow{KH}[/tex]
[tex]M(x,y) = K(x,y) + \frac{1}{2}\cdot [H(x,y)-K(x,y)][/tex] (2)
If we know that [tex]K(x,y) = (2, 1)[/tex] and [tex]H(x,y) = (4,3)[/tex], the coordinates of the intersection of the diagonals of the parallelogram are:
[tex]M(x,y) = (2,1) + \frac{1}{2}\cdot [(4,3)-(2,1)][/tex]
[tex]M(x,y) = (2,1) + \frac{1}{2} \cdot (2,2)[/tex]
[tex]M(x,y) = (2,1) + (1,1)[/tex]
[tex]M(x,y) = (3,2)[/tex]
Therefore, the coordinates of the intersection of the diagonal of the parallelogram are [tex]M(x,y) = (3,2)[/tex].
Write an equation describing the relationship of the given variables. y varies inversely as the cube root of x and when x=125, y=8.
Answer:
y = 40 / x^1/3
Step-by-step explanation:
Given that :
y α x^1/3
y = k * 1 / x^1/3
y = k / x^1/3
When x = 125 ; y = 8
8 = k / 125^1/3
Cube root of 125 = 5
8 = k / 5
8 * 5 = k ; k = 40
Hence, expression becomes :
y = 40 / x^1/3
y α k/∛x is the relationship of the variables x and y whose values are 125 and 8.
What is Equation?Two or more expressions connected with an equal sign is called Equation.
The relationship of the given variables. y varies inversely as the cube root of x.
By given data we can write as
y α k/∛x
The cube root of 125 is 5.
y α k/∛125
y α k/5
8=k/5
k=40
Hence y α 40/∛x is the relationship of the variables x and y whose values are 125 and 8.

Enter your answer in the box.
x =?
Answer:
4(5x-20)=-20 should be x=3
Answer:
x = 3
Step-by-step explanation:
4(5x−20)=−20 | Given
20x - 80 = -20 | Distribute the number on the outside (multiply all numbers on the inside by the number on the outside, 4×5x and 4×-20)
20x = 60 | Add 80 to both sides (do the opposite operation, if its a negative number add it to both sides)
x = 3 | Divide both sides by 20x (20x turns into x and 60 turns into 3 via 60÷20)
Simplify the given equation.
17x - 6 + 3x - 5 = x + 11 + 4x
Answer:
x = 22/15
Step-by-step explanation:
17x - 6 + 3x - 5 = x + 11 + 4x
= (17x + 3x) (-6 - 5) = x + 11 + 4x
= 20x - 11 = x + 11 + 4x
= 20x - 11 = (x + 4x) + 11
= 20x - 11 = 5x + 11
= 20x - 5x = 11 + 11
= 15x = 22

Answer:
2.4 or [tex]\frac{12}{5}[/tex]
Step-by-step explanation:
In the divisor (the second fraction) we flip the numerator and the denominator. This is known as the reciprocal and basically it means the reverse of the fraction. When we find the reciprocal, we also have to change the division sign to a multiplication sign.
Once you've flipped the second fraction and changed the symbol from divide to multiply, we can multiply the numerators together and the denominators together and we have our solution:

A shirt that cost 60 dollars is now on sale for 30% off what is the value of the discount? Using the answer you found to find the difference between the original price and the amount of the discount
Answer:
you $42 and your saving $18
Step-by-step explanation:
Answer:
$42 would be the cost of the shirt after the discount. The difference between the price of the shirt before the discount, and after is $18.
Step-by-step explanation:
If you divide 60 by 100, you would get the value for 1% of $60. If you multiply that number by the discount amount, you get the amount that is going to be subtracted from the cost when the discount is applied.
60 / 100 = 0.6
0.6 x 30 = 18 (This is the difference)
60 - 18 = 42 (This is the value after the discount)
Thus the value after the discount is $42, and he difference between the 2 values is $18.
