Answer:
see explanation
Step-by-step explanation:
Consider the left side
A +
A - 2cos²Asin²A ← is the expansion of
= (cos²A - sin²A)²
Substitute sin²A = 1 - cos²A
= (cos²A - (1 - cos²A) )²
= (cos²A - 1 + cos²A)²
= (2cos²A - 1 )²
= right side , then proven
Good evening
x^0+y^0 for x=3 and y=2
First thing we need to do is to replace their value
3^0+2^0
Remember: Any number that raised to the zero power equal 1
so now we have
3^0=1 and y^2=1
1+1
= 2
I hope that's help :0
Any Questions /
Answer:
Volume of prism = 39 km cubed
Step-by-step explanation:
<u>IMPORTANT FORMULA: Volume of any prism = Area of base * Height </u>
<u />
In this case, <u><em>the area of the base</em></u> means <u><em>the area of the trapezoid. </em></u>
Area of trapezoid = base1+base2/2 * height
Area of trapezoid = 8+5/2 * 1.5
Area of trapezoid = 13/2 * 1.5 = 9.75
We already know that the height of the trapezoidal prism is 4 kilometers.
So, we have all of the values that are needed to correctly fill in the formula.
Volume of the prism = 9.75 * 4 = 39
