Answer:
1/125
Step-by-step explanation:
(5^-2)(5^-1) = 5^-3=1/5^3=1/125
Answer:
Use area of trap formula and special right triangles
Step-by-step explanation:
A = (.5)(10 + 18)(5)
The y intercept is when x is 0. So, we have to plug in 0 for x. You can do this in many different ways as well.
7(0)-4y=8
-4y=8
Divide both sides by -4.
Y=-2
So, the Y intercept is -2 (0,-2).
The 0.072 will be you're answer
Answer:
14)
21√2
15)
Leg: 7√3
Hypotenuse: 14
Step-by-step explanation:
The hypotenuse is √2 as long as each leg. That means the leg is 42/√2. Simplified to make 21√2.
The hypotenuse is always twice as long as the shortest leg on a 30-60-90 triangle. The longer leg is √3 as long as the shortest side.
