Answer:
The answer to your question is: a = 3.5 units
Step-by-step explanation:
Right triangle
to find a we need to use the trigonometric function cosine
cosine Ф = opposite leg / hypothenemus
Clear opposite leg from the equation
opposite leg = hypothenemus x cosine Ф
a = opposite leg = 5 x cosine 45
a = 5 x 0.70
a = 3.5 units
Answer:
- sign between 9 and 64 under root, it should be + sign
Step-by-step explanation:
(-4)*(-8)(2)= 64
It should read x= √9+64 but not √9-54 which lead to incorrect solution
Answer:
x^2 - 25 ✔
Step-by-step explanation:
(x+5)(x-5)
x(x-5) +5(x-5)
x^2 - 5x + 5x - 25
x^2 - 25
Answer:
62
Step-by-step explanation:
The enclosing rectangle is 24 units long and 12 units high. Its area is ...
(24 units)(12 units) = 288 square units
The white circles obviously cover more than half the area, so the only viable answer choice is 62.
__
If you want to go to the trouble to actually figure it out, you can find the area of each circle using the area formula ...
A = πr² = (3.14)(6²) = 113.04
Then both circles have an area of 2×113.04 = 226.08, and the shaded area is the difference between that and the rectangle area:
shaded area = 288 -226.08 = 61.92 ≈ 62
