You need to use some trig... but I will try to explain it as best as possible. If you imagine a unit circle, we describe the coordinate points that line on the circle in terms of cosine and sine. A certain coordinate point on the circle can be written like (cos(x),sin(x)). "X" is going to be the angle from the center of the circle starting at point (1,0). Now imagine this triangle being fitted into a circle. The leg represents the x and y length that lead up to a point on the circle. The hypotenuse of the triangle represents the radius of the circle.
We need to find the hypotenuse first.
cos(37 degrees) x hypotenuse = 2.1
hypotenuse = 2.63 approx.
So the "x" length or the sine length is...
sin(37 degrees) x 2.63 = 1.6 approx.
answer: 1.6
2,376 square feet
**
Add the areas of all the sides of the shape.
A triangle's area: 1/2bh
The two triangles' area=24*9=216
The bottom side: 40*24=960
The two other sides: 30*40=1200
Add everything: 216+960+1200=2376
Answer:
x > -24 and graph in picture below
Step-by-step explanation:
-1/4x + 2 < 8
-2 -2
-1/4x < 6
(-4) (-4)
x > -24
1:This is a parabola by the looks of the equation and the fact that it's a
satellite dish. The vertex of the equation is (-6,0) and the focus is
2/4, 1/2. 1/2 plus -6 is -5.5. the focus is (-5.5,0).
This answer is only true if the actual equation is y^2 not 2y
2:<span>y=-(x+3)^2/8+1
3:</span>This is the answer(–1.25, –3),
4:
answer is: x^2=-12y
Answer:
17
Step-by-step explanation:
4 × 5 - 3² x 2 ÷ 6
20 - 3² × 2 ÷ 6
20 - 9 × 2 ÷ 6
20 - 18 ÷ 6
20 - 3 = 17
