C.

D.
counterclockwise 90°

Answers

Answer:

C. counterclockwise 180°

Step-by-step explanation:

Hi! A and B are definitely not the right answers, because that’s basically rotating it forward even more. Rotating a polygon in Quadrant II 370 degrees clockwise is like rotating it 99 degrees counterclockwise, because the next 90 degrees you were to rotate it, it would be in it’s original position. The answer is C.

I have an answer for the last image.. The first step to finding the y-coordinate of the vertex of the equation y= -2x^2+2x-3 given that the x-coordinate of the vertex is 1/2 is the last option: -2(1/2)^2+2(1/2)-3.. The variable x represents the x-coordinate which means that all you have to do to start is plug in the vertex they gave you: 1/2

Write an expression for the quotient of the quantity m reduced by 3 and 5.

Answers

Answer:

\displaystyle(m-3)/(5)

Step-by-step explanation:

Let us translate it step by step:

m reduced by 3 is subtracting from m, therefore: m - 3

Then the quotient of that and 5 is the division or fractions of m-3 over 5:

\displaystyle(m-3)/(5)

That is the expression for the quotient of the quantity m reduced by 3 and 5.

A radioactive kind of nitrogen has a half-life of 10 minutes. If you start with 64 grams of the substance, how much will be left after 20 minutes

Answers

There would be 16 grams left after 20 minutes.
64/2 = after ten minutes
= 32
32/2 = after another ten minutes (20 full)
= 16

Answer:

30

Step-by-step explanation:

First, find out how many half-lives have passed. Divide the number of minutes by the length of a half-life.

20÷10=2

2 half-lives have passed.

Now figure out how much nitrogen will be left after 2 half-lives have passed. Multiply the starting amount of nitrogen by

1/2

a total of 2 times.

120x1/2 1/2=30

That calculation could also be written with exponents:

120x(1/2)2=30

After 2 half-lives, the amount of nitrogen left will be 30 grams.
