Tan^2 x - Tan^ x sin^2 x
= tan^2x ( 1 - sin^2 x)
= tan^2 x * cos^x
= sin^2 x * cos^2 x
----------------------
cos^2 x
= sin^2 x
Answer:
Explanation: As you make the segments smaller and smaller, the parallelogram becomes more of a rectangle with shorter side equal to the radius of the circle r and longer side πr - half of the circumference of the circle. Hence we get the formula πr2 for the area of a circle of radius r .
Step-by-step explanation:
Answer:
a= about 2.7 pounds of apples
Step-by-step explanation:
2.14=0.99a-0.50
2.64=0.99a
Should be 40ft. If not, I dearly apologize.
Given is a parallelogram whose base is b = 10 inches and it says height is 2 more than half-value of base i.e. h = 2 + (b ÷ 2).
So height is h = 2 + (10 ÷ 2) = 2 + 5
⇒ h = 7 inches.
We know the formula for area of parallelogram is given as follows :-
Area of parallelogram = base x height
Area of parallelogram = 10 inches x 7 inches
Area of parallelogram = 70 squared inches.
Hence, the final answer is 70 squared inches.
