Answer:
sqrt(10) *x
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2
x^2 + (3x)^2 = hypotenuse ^2
x^2 + 9x^2 = hypotenuse ^2
10x^2 = hypotenuse ^2
Take the square root of each side
sqrt( 10x^2) = sqrt(hypotenuse ^2)
sqrt(10) * x = hypotenuse
Answer:
D
Step-by-step explanation:
the center is (0,8)
(to solve this just flip the signs on the constants being added to x and y (there is an invisible constant of 0 being added to the x))
the radius is 7 (or √49)
Your answer would be the 4th one : time 10%4=10/4
Answer:
A
Step-by-step explanation:
You divide the diameter by 2 to get radius. So 5÷2=2.5
So then you multiply 2.5 by pi aka 3.14 so 2.5x3.14=7.85 So we rounds 7.85 to 7.9
Answer: b. y=5
Step-by-step explanation:
Take the cube root of both sides.
![y=\sqrt[3]{125}](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7B125%7D)
Calculate.
y=5
