Answer:
4. 22
5. 1
Step-by-step explanation:
i hope this helps
$95 × 20% = $19
anything to ask please pm me
since the polygon has 8 chambers the angle of one chamber = 360/8 = 45°
so the angle WOP = 45°
now drawing a imaginary line which seperates the triangleWOP into half
so the angle of imaginary line is 45/2 = 22.5
sin(theta) = opp/hyp
since WP (opp) is unknown. take as x
sin(22.5) = x/44
0.383×4 = x
x = 1.532 (app) = 1.5 cm
perimeter = 1.5 × 8
= 12 cm
area of triangle WOP = 2×1/2 ×bh = bh
= 4×1.5
= 6 cm²
so the area of regular polygon = 8× area of a triangle
= 48 cm²
Answer: Linear model 
and H'(t) = 9 units.
Step-by-step explanation:
Since we have given that
In 2000, amount spent = $100 billions
In 2010, amount spent = $190 billions.
So, rate of increase would be
So, linear model for H(t) would be
So, H'(t) would be 9.
Hence, linear model and H'(t) = 9 units.
The answer is a because if you do the math right the it will come up at 4, 9 which means that state a double as much as B
