The only ordered pair that appears on the graph is A) (2,1)
Answer:
24 units ²
Step-by-step explanation:
In this problem, we are given the circumference of a triangle (after finding the perimeter) and want to find the area of a circle with that circumference. Since the area of a circle is a function based on its radius, we can use the circumference to find the radius to find the area.
First, we can figure out the perimeter of the triangle, which is equal to the sum of its sides. The perimeter is 6+4+7.21 = 17.21 units.
Next, the circumference of a circle is equal to π * diameter = π * 2 * radius. Using 3.14 for π and r for radius, we get
3.14 * 2 * r = 17.21
6.28 * r = 17.21
divide both sides by 6.28 to isolate r
r ≈ 2.74
Furthermore, to find the area from the radius, we can use
area = πr². Plugging 2.74 in for r, we get
2.74² * 3.14 = area
≈23.6, rounding up to 24 units ²
Answer:
1. 1/3 and 3
2. 4 and 4
Step-by-step explanation:
Your monthly payment on the house will be $1815.52
First I multiplied $ 351,749 by .15 (or 15%), and I got $52762.35
Then I minus $52762.35 from $ 351,749, because you are going to pay that much for down payment. I get $298986.65
Then I multiply $298986.65 by .093 (or 9.3%), and I get $27805.75845 (round it up to $27805.76)
Then I add $298986.65 and $27805.76 equals $326792.41
Then I calculate how many months there are in 15 years, by simply multiplying 12 and 15, get 180
So I divide $326792.41 by 180 and TADA!!! You get the answer
I get 1815.5133 (round it up to $1815.51)
so if you do 1/tan(10) in the calculator you get 5.67128
round the answer as needed
