Answer: it will take 0.33 years for the heights to be the same.
Step-by-step explanation:
Let x represent the number of years it will take for both trees to be the same height.
Type A is 7 feet tall and grows at a rate of 2 inches per year. This means that the height of the tree after x years would be
2x + 7
Type B is 2 feet tall and grows at a rate of 17 inches per year. This means that the height of the tree after x years would be
17x + 2
For the heights to be the same, the number of years would be
17x + 2 = 2x + 7
17x - 2x = 7 - 2
15x = 5
x = 5/15
x = 0.33 years
Answer: $20,790
Step-by-step explanation:
The sales revenue increased by 5% from 2018 to 2019.
The sales revenue that was increased from in 2018 is $19,800 which means that the 2019 sales revenue is 5% more than $19,800.
To find the sales revenue in 2019, do the following:
= 19,800 + (19,800 * 5%)
= 19,800 + 990
= $20,790

Answer:

The center is:
(2, -4)
Step-by-step explanation:
We have the following equation

The general equation of a circle has the following form

Where r is the radius and the point (h, k) is the center of the circle
To transform the given equation in the general equation of a circumference we must use the method of square completions
Step 1

<u>Step 2</u>
<u> </u>Add and subtract
For an equation of the form


<u>Step 3 </u> Factor the expressions within the parentheses

<u>Step 4 Simplify</u>


Finally

The center is:
(2, -4)
From 72 to 90 it is a 25% change
