Answer:
Step-by-step explanation:
If the corner of your porch is the origin
- 4 ft to the left, x=-4
- 5 ft in front, y=5
The tree's location is at (-4,5).
- A circular fence 3 ft in radius has its center at the tree(-4,5).
We want to determine the equation of a circle with center (-4,5) and radius 3 ft.
The equation of a circle center (h,k) with a radius of r is given as:
(h,k)=(-4,5), r=3
The equation formed by the fence therefore is:
Answer: <u>The 2 roads are 1.25 miles apart.</u>
Step-by-step explanation:
If 1 inch equals .25 miles, then you need to multiply .25 by 5.
Use proportions. Make sure the miles are on the same "side" of the fraction. Side meaning the top or the bottom
1 times X equals 1x
.25 times 5 equals 1.25
1.25 divided by 1 equals 1.25.
A = 12.5
2/5 = 0.4
5/0.4 = a
Answer:
True
Step-by-step explanation:
this funcion is squared and you can draw it, so therefore it is a function.
The exact value of arcsin ( 2 √ 2 ) is π4.
