Answer:
see below
Step-by-step explanation:
f(x) = 5x^3 +1, g(x) = – 2x^2, and h(x) = - 4x^2 – 2x +5
f(-8) = 5(-8)^3 +1 = 5 *(-512) +1 =-2560+1 =-2559
g( -6) = -2 ( -6) ^2 = -2 ( 36) = -72
h(9) = -4( 9)^2 -2(9) +5 = -4 ( 81) -18+5 = -324-18+5=-337
I'm assuming that you meant to add an attachment
but log168 is equal to 2.22530928173
so simply solve the presumed answer choices
The one that equals 2.22530928173 is equivalent to log168

Answer: D) 155
Step-by-step explanation:
let <A, <B,<C are three angles in a triangle.
sum of the three angles in a triangle is 180degree.
<A+<B+<C=180
130+<B+<C=180 since one angle is given
<B+<C =180-130
<B+<C=50
(<B+<C)/2=25----(1)after bisecting sum of the angles
required angle =180-25=155
d is correct answer
Answer:
21.46 cm²
Step-by-step explanation:
because the question want only for the SHADED REGION but NOT AREA OF THE SQUARE
(if we just multiply 10x10. you will get the area of a square which is hundered)
To find the shaded region:
1. area of a circle is πr² (we have 4 circle there)
2. Find the area of all circle
# how do we know the radius?
- half of 10 is 5
- 5 is the diameter of each circle
- the radius is half of 5 which is 2.5
- π(2.5)² = 25/4π (area of 1 circle)
3. since we have 4 circle then, 25/4π x 4 = 25π
4. the area of the square is 100cm²
5. we want the shaded region so we have to minus the area of the circle
6. 100 - 25π (use your calculator to find the answer)
answer should be 21.46 cm²
(hope this helps)
