Answer:
6
Step-by-step explanation:
It is in the fourth quadrant
(Base * Height)/2 = Area of triangle (in unit squared) - putting this equation to this we get :
(3.5 * 2.5)/2= <span>square feet</span>
8.75/2 = 4.375 square feet
So the area to make one triangular flag is 4.375 square feet. So the cost to make one flag is:
4.375 * cost per square foot = cost per flag
4.375 * 0.40 = $1.75
The answer is $1.75.
Note: Apologies if I didn't spell square foot or feet right - I am from New Zealand and we work in meters.
Step-by-step explanation:
sec⁴B - sec²B = sec²B(sec²B - 1)
= (1 + tan²B)(tan²B)
= tan⁴B + tan²B
= Right-hand side (Proven)
