It is eight if u read the last part by the way says so that makes it 8
Answer:
Center: (0,0)
Radius: 5
Step-by-step explanation:
Let O(xo,yo) be the center (of the circle) with the coordinates xo, yo.
If R is the radius, then we have:
(x-xo)²+(y-yo)²=R².
In our case: x²+y²=25, the center is at (0,0), and R²=25, so R=5
Answer:
13/12 x²
Step-by-step explanation:
x / 12 x + x²
Rewrite
x / 12 x + x + x²
Write the division as fraction
1/12 x + x + x²
Calculate the product
1/12 x² + x²
calculate the sum
13/12 x²
Answer:
B
Step-by-step explanation:
Using the cofunction identity
sin x = cos(90 - x)
Given
sin(3x + 19) = cos(5x - 25), then
3x + 19 = 90 - (5x - 25)
3x + 19 = 90 - 5x + 25
3x + 19 = 115 - 5x ( add 5x to both sides )
8x + 19 = 115 ( subtract 19 from both sides )
8x = 96 ( divide both sides by 8 )
x = 12 → B
