Answer:

Zero is even (not odd, not neutral)

Zero is neither positive nor negative (the only number with this property)

Zero is an integer (and must be considered when question limits choices to integers)

Zero is a multiple of all numbers (x*0 = 0, so a multiple of any x)

Step-by-step explanation:

Any number to the power of 0 is equal to 1. 0 is neither positive nor negative. 0 is neither prime nor composite. If you add two numbers and the sum is zero, we call the two numbers additive inverses or opposites of each other.

When Vlad moved to his new home a few years ago, there was a young oak tree in his backyard. He measured it once a year and foun

Anestetic [448]

Answer:

The tree was 175 centimeters tall when Vlad moved into the house.

7 years passed from the time Vlad moved in until the tree was 357 centimeters tall.

Step-by-step explanation:

The height of the tree, in centimeters, in t years after Vlad moved into the house is given by an equation in the following format:

$H(t) = H(0) + at$

In which H(0) is the height of the tree when Vlad moved into the house and a is the yearly increase.

He measured it once a year and found that it grew by 26 centimeters each year.

This means that $a = 26$

$H(t) = H(0) + 26t$

4.5 years after he moved into the house, the tree was 292 centimeters tall. How tall was the tree when Vlad moved into the house?

This means that when t = 4.5, H(t) = 292. We use this to find H(0).

$H(t) = H(0) + 26t$

$292 = H(0) + 26*4.5$

$H(0) = 292 - 26*4.5$

$H(0) = 175$

The tree was 175 centimeters tall when Vlad moved into the house.

How many years passed from the time Vlad moved in until the tree was 357 centimeters tall?

This is t for which H(t) = 357. So

$H(t) = H(0) + 26t$

$H(t) = 175 + 26t$

$357 = 175 + 26t$

$26t = 182$

$t = \frac{182}{26}$

$t = 7$

7 years passed from the time Vlad moved in until the tree was 357 centimeters tall.
