Answer:

Option C; Option D; Option E

Step-by-step explanation:

~ The volume of this prism is calculated through the general Base * height formula, in other words length * width * height ~

Here the length ⇒ 2x + 5, the width serves as ⇒ 2x- 5, and the height ⇒ 3x

1. Knowing the dimensions, let us apply the formula length * width * height to substitute and simplify to the point: ( 2x + 5 ) * ( 2x - 5 ) * ( 3x )

2. Through the process of simplification, we derive the answer ( s ):

( 2x + 5 ) * ( 2x - 5 ) * ( 3x ) = 3x * ( 4x^2 - 25 ) =

( 3x ) * ( 2x )^2 - ( 5 )^2 = 12x^3 - 75x; Option C

3x * ( 4x^2 - 25 ); Option D 

or ⇒ ( 2x + 5 ) * ( 6x^2 - 15x ) =

( 2x + 5 ) * ( 2x - 5 ) * ( 3x ) = 12x^2 - 75x; Option C

( 2x + 5 ) * ( 6x^2 - 15x ); Option E

The coordinates of DEF are D(3,4), E(6,4), and F(5,9). If you translate DEF 3 units left and 2 units up, what are the coordinate

grigory [225]

EXPLANATION:

1.We must locate the points that the exercise gives us in the Cartesian plane.

2.The figure that it gives us must be moved 3 units to the left and then 2 units up.

3.To correctly translate a figure, we must add the units that the exercise indicates and towards the correct direction, if it tells us that to the left is towards the negative axis, then each of the points given in the exercise we will transfer 3 units towards the left and then add each of the points two units up, then we see that the triangle takes new coordinates for the points.

4.The new coordinates for point E are (3,6)

In the late nineteenth century, the scientist Marie Curie performed experiments that led to the discovery of radioactive substan

gtnhenbr [62]

Answer:

Step-by-step explanation:

Half life is the time taken by a radioactive substance to reduce of half of its original size

If the half life of radium is 1600, this means that the original radioactive substance N0 have reduced to N0/2 after 1600 years

if we are given N0 = 1000grams

The amount of the substance that will remain after 1600 years will be N0/2 i.e 1000/2 = 500g

Hence 500 grams of radium will be left after 600years
