Answer:

Scale factor(k)defined as the ratio of image to the pre-image i,e

k = \frac{\text{Image}}{\text{Pre-image}}

Volume of a prism is given by:

V = A \cdot h

where

V is the volume of the prism

A is the base Area

h is the height.

As per the statement:

A prism with a base area of 3 m² and a height of 4 m

⇒Base area(A) =  3 m² and height(h) = 4 m

Then by definition of volume of prism

Volume of the original prism = 3 \cdot 4 = 12 m^3

Since, the prism is dilated by a factor of 3/2

⇒k = \frac{3}{2}

then by definition of scale factor:

k= \frac{\text{Dilated volume of prism}}{\text{Original prism}}

Substitute the given values we have;

\frac{3}{2} = \frac{\text{Dilated Volume of prism}}{12}

Multiply both sides by 12 we have;

\text{Volume of dilated prism} = 12 \cdot \frac{3}{2} = 6 \cdot 3 = 18 cubic meter

Therefore, the volume of dilated prism is, 18 m^3

Volume of Original Prism = base area * Height = 3 * 4 = 12

After dilation factor = 12 * 3/2 = 6 * 3 = 18

In short, Your Answer would be 18 m³

Hope this helps!

Factor 9x6 – 16 y completely.
sveticcg [70]

Answer:

(3x^3 - 4y^3) ( 3x^3 + 4y^3)

Step-by-step explanation:

9x^6 – 16 y^6

Rewriting as

(3x^3) ^2 - ( 4y^3) ^2

This is the difference of squares a^2 - b^2 = (a-b)(a+b)

(3x^3 - 4y^3) ( 3x^3 + 4y^3)

The midpoint M and one endpoint of JK are given. Find the coordinates of the other endpoint. J(7,2) and M(1,-2)
djverab [1.8K]

Step-by-step explanation:

Xj + Xk/2 = Xm

7 + Xk/2 = 1

to get rid of the bracket, multiply all two sides by the denominator.

2(7 + Xk/2) = 1(2)

7 + Xk = 2

Xk = 2 - 7

Xk = -5

Yj + Yk/2 = Ym

2 + Yk/2 = -2

to get rid of the bracket, multiply all two sides by the denominator.

2(2 + Yk/2) = -2(2)

2 + Yk = -4

Yk = -4 - 2

Yk = -6

Therefore the coordinates of point K is (-5,-6)

Which equation below would be perpendicular to the line y = 2?
nadya68 [22]
Answer:
A) y=1/5x
Step-by-step explanation:
Coz, the way you identify a perpendicular line is by looking for its negative reciprocal. The neagtive reciprocal of 5= 1/5
Now, to check the ans we can multiply the negative reciprocal by "m"
(m in y=mx+c or y=mx+b)
in this case the "m" is stated as 5, so all we need to do is 1/5*5 if the ans is 1 then your ans is right....and over here it is
So thats how you identify & check perpendicular lines!

Determine the answer to 3 + -5 and explain the steps using a number line
Marizza181 [45]
Adding a positive to a negative, you would look at the number with the greater absolute value, and that number would determine the sign of the sum. 

5 - 3 = 2

Since 5 is bigger, you use that sign

-5 

-2

Answer: -2
