Answer:
95.49°
Step-by-step explanation:
The arc length formula is s = rФ, where r is the radius and Ф is the central angle in radians. Here, r = 9 ft and s = 15 ft. Thus, the central angle Ф is
Ф = (15 ft) / (9 ft) = 5/3 radians, or
5 rad 180°
------- * ---------- = 95.49°
3 π rad
Answer: D
You get the same answer from doing both!
It's a parallelogram so if one angle is 90 degrees they all will be because of transverse angles and all that good stuff.
So we're given the diagonal of a rectangle and one side and we're asked to find the other. The diagonal of a rectangle is the hypotenuse of the right triangle whose legs are the sides of the rectangle. So this is a Pythagorean Theorem question in disguise:
Answer: 140 cm
I don't recall seeing this Pythagorean Triple before.
Answer:
a function
Step-by-step explanation:
no repeating numbers
Answer:
(x+4) (x-8)
Step-by-step explanation:
The function is represented by the zeros
(x-a) (x-b) ....... = 0 where a,b,..... are the zeros
There are 2 zeros so there are 2 factors
( x- -4) ( x-8) = 0
(x+4) (x-8) =0
