The height of a tree is 56 inches. After 5 years, the height is 10 feet 11 inches. How many inches did the tree grow each year?
ra1l [238]

The tree grows 15 inches each year

<h3>Calculating the rate of growth </h3>

From the question, we are to determine how many inches the tree grows each year

First, we will calculate the difference in height

Initial height = 56 inches

Final height = 10 feet 11 inches = 131 inches

Difference in height = 131 inches - 56 inches

Difference in height = 75 inches

Now, for the rate at which the tree grows each year,

The rate at which the tree grows each year = 75 inches / 5 year

The rate at which the tree grows each year = 15 inches/year

Hence, the tree grows 15 inches each year.

Midpoint of (2,4) and (2, -7)
slega [8]

Step-by-step explanation:

soln:

let,

(x1,y1) =(2,4)

(x2,y2)=2,-7)

Now,

By midpoint formula,

×= <u>x</u><u>1</u><u>+</u><u>x</u><u>2</u>

2

= <u>2</u><u>+</u><u>2</u>

2

=<u>4</u>

2

=2,,

And,

Y=<u>y</u><u>1</u><u>+</u><u>y</u><u>2</u>

2

=<u>4</u><u>-</u><u>7</u>

2

= <u>-</u><u>3</u>

2

Hence ,

The mispoint between points (2,4) and (2,-7) is (2,<u>-</u><u>3</u><u> </u><u> </u><u> </u><u>)</u>
