Answer:
3
Step-by-step explanation:
The exponent is 3 because of the ^
Answer:
3 because you plug y into x and you have to get o for y
The values of sin cycle on the domain 0 to 2π
The value of sin(π/2) = 1
The value of sin(2π/2) = 0
The value of sin(3π/2) = sin(π + π/2)= -1
Therefore, if the angle can be written as:
nπ + π/2, where n is any odd number, the value of sin(nπ + π/2) = -1
sin(11π/2) = sin(5π + π/2) = -1
Answer:
x=7
Step-by-step explanation:
if you look at this diagram as 2 triangles, the little one, and then the big one that the little one is inside of, and realize that they are similar triangles (by AAA standards) you can use a ration to solve the answer. the side length 9 is the length that is similar to side length 21, so you put those in a fraction format (9/21), and side length 3 is similar to side length x so you put those in a fraction (3/x), and then you create a ration with those
9/21=3/x
now you can cross-multiply 21 times three (63) and divide that number by 9 (7) to get your final answer of x=7.
Hope this helps!
