Answer:
12 in
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = h(b₁ + b₂ )
where h is the height and b₁, b₂ the parallel bases
Given h = 6, b₁ = 8 and A = 60 , then
× 6 × (8 + b₂ ) = 60 , that is
3(8 + b₂ ) = 60 ( divide both sides by 3 )
8 + b₂ = 20 ( subtract 8 from both sides )
b₂ = 12
The length of the second base is 12 inches
Answer:
Wheres is the figure?
Step-by-step explanation:
Answer:
The believe the function is 3.
Answer:
<u>f(x) = x² - 4x + 2 or f(x) = (x - 2)²</u>
Step-b<u>y</u>-step explanation:
- The parabola touches the x-axis at only one point
- If we use y = a(x − h)² + k, we can see from the graph that h = 2 and k = 0
- This gives us y = a(x − 2)²
What is the value of "a"?
- We also see that the y-intercept is (0, 4)
- We can plug it into the equation
- 4 = a(0 - 2)²
- 4a = 4
- a = 1
<u>So, our quadratic equation will be</u> :
- y = 1(x - 2)²
- <u>y = x² - 4x + 2 or y = (x - 2)²</u>
Answer:
Step-by-step explanation: 2cos3 theta=1. Cos 3theta=1/2. Since cos 60°= 1/2. Therefore cos 3theta=cos 60°. Theta=20°.
