Step-by-step explanation:
f(x) = 3x² - 2x + 7
f(-2) = 3(-2)² -2(-2) + 7
= 3(4) + 4 + 7
= 23
I am almost positive that it is 360
Answer:
Aha..our nemesis problem. :)
The area is 129.90 ft ^2.
Step-by-step explanation:
First, use a 30-60-90 triagle to find the apothem.
That is the area of 1 triangle. There are 6 of them in a hexagon, so multiply that number by 6:
21.65*6=129.90 ft ^2
Have a great day!
Answer:
Ratio of circumferences:
Ratio of radii:
Ratio of areas:
Step-by-step explanation:
Hi there!
We are given:
- The circumference of Circle K is
- The circumference of Circle L is
Therefore, the ratio of their circumferences would be:
⇒ when simplified
The formula for circumference is , where <em>r</em> is the radius. To find the ratio of the circles' radii, we must identify their radii through their given circumferences.
If the circumference of Circle K is , or , then its radius is .
If the circumference of Circle L is , then its radius is , which is 2.
Therefore the ratio their radii would be:
⇒ ⇒ when simplified
The formula for area is:
First, let's find the area of Circle K:
Now, let's find the area of Circle L:
Therefore, the ratio of their areas would be:
⇒ ⇒ ⇒ when simplified
I hope this helps!
This statement describes a range of Micah's salary.
The range is a number that describes the distance from the beginning of something to the end of something.
In this scenario the beginning would be the beginning salary, in the end salary would be where you stop at end at after adding $876.
$1793(starting) + $876 = $2669
The maximum amount of money that Micah could earn would be $2669.
