Answer:

1. No vertical compression or stretching but will open up downward.

2. 1/4 vertical stretch

3. 4 vertical compression

Step-by-step explanation:

Any time your dealing with vertical stretching or compression it will always be the number before the parentheses.

So in 1. it is - or basically -1 which means the parabola will be open up downward. And in this problem there is no stretching or compression

2. Is the 1/4 is a vertical stretch

3. 4 is a vertical compression.

Or what also could help is when the number before the parentheses is bigger such as number 4 the closer together the parabola will be. And the smaller the number like 1/4 the wider the parabola will be.

What is 328.618 round to the nearest hundredth A. 300 B. 328.60 C. 330 D. 328.62

son4ous [18]

Answer:

D. 328.62

Step-by-step explanation:

328.618 round to the nearest hundredth

Rounding to the nearest hundredth means 2 numbers after the decimal point

Numbers that rounds to 1 are 5, 6, 7, 8, 9

Number that rounds to 0 are 0, 1, 2, 3, 4

When rounding up, to the nearest hundredth, you will consider the next number after the two figures after the decimal point

Here, the next number after the two figures after the decimal point is 8

8 is a number that rounds to 1

Therefore, add 1 to 1 to have

Which of the following is the simplified expression of 2 square root of -16 + the square root of 225 in standard form, a plus b

LuckyWell [14K]

Answer:

The standard form like $(a+bi)$ will be: $15+8i$

Step-by-step explanation:

Given expression is: $2\sqrt{-16}+\sqrt{225}$

First factoring out -16 as (-1×16) , we will get....

$2\sqrt{-1}*\sqrt{16}+\sqrt{225}$

Now, replacing $\sqrt{-1}$ as $i$ .......

$2i\sqrt{16}+\sqrt{225}$

Finally, simplifying the radicals in the above expression, we will get......

$2i*4+15\\ \\ =15+8i$

Thus, the standard form like $(a+bi)$ will be: $15+8i$
