Use the slope formula or since it's a straight line crossing the y axis at one, it means the y=1
Idk! Is there a picture to show us?

Answer:
779.4 square units
Step-by-step explanation:
You seem to have several problems of this type, so we'll derive a formula for the area of an n-gon of radius r.
One central triangle will have a central angle of α = 360°/n. For example, a hexagon has a central angle of α = 360°/6 = 60°. The area of that central triangle is given by the formula ...
A = (1/2)r²sin(α)
Since there are n such triangles, the area of the n-gon is ...
A = (n/2)r²sin(360°/n)
__
For a hexagon (n=6) with radius 10√3, the area is ...
A = (6/2)(10√3)²sin(360°/6) = 450√3 ≈ 779.4 . . . . square units
Answer:
a) 217
b) 1351
c) 5403
Step-by-step explanation:
Given that:
confidence interval (c) = 0.95

The Z score of
is from the z table is given as:

Range = $45000 - $30000 = $15000
The standard deviation (σ) is given as:

Sample size (n) is given as:

a) E = $500
≈ 217
b)
≈ 1351
c)
≈ 5403
Area of Trapezoid = h(b1+b2/2)
b1 and b2 are the lengths of each base and h is the height.
Area = 16(20+24/2)=352 Square Feet
352/20=17.6 Cans of paint.
Hope this helps and is correct, I haven't done this kind of math in a while.
