17.82 because you just take the 18% of 99 which is 0.18
F(x)=2x²+5√(x-2)
f(3)=2(3)²+5√(3-2)
= 2 (9) + 5√1
= 18 + 5
= 23.
Answer:
519.6
Step-by-step explanation:
A hexagon has a total of 720 for it's interior angles so each angle is 120 and in the triangle, each of them is 60, making it an equilateral triangle. You can use 30 60 90 triangles to find the height which is 5√3.
(5√3)*10=50√3
The area of the triangle times 6 is 300√3 which is approximately 519.6
Answer:
x = 6
y = 7
a = 1/4
Step-by-step explanation:
Equation 1:
2(3x+2) = 2x + 28
6x + 4 = 2x + 28
4x = 24
x = 6
Equation 2:
5y+13 = -43-3y
8y = -56
y = -7
Equation 3:
8a + 8 = 16 - 24a
32a = 8
a = 1/4
Answer:
D) 1/2
Step-by-step explanation:
<u>Dilation</u> : a type of transformation that makes the figure larger or smaller.
<u>Scale factor</u> : number or the conversion factor which is used to change the size of a figure without changing its shape.
Scale factor = dimensions of the new shape ÷ dimensions of the original shape
Given:
- Length of new figure P'Q' = 3 units
- Length of original figure PQ = 6 units
Therefore, scale factor = 3 ÷ 6 = 1/2
