Answer:
The answer is b.
Step-by-step explanation:
Square root 124, you'll get 29.10, after that once you simplify it, you will get the answer and you will have to do the formula, a^2 + b^2 = c^2 since it is a triangle.
You're pretty close. It's all in the details.
A. Correct.
B. Correct.
C. Sign error in the boxed answer. -(-0.5) = 0.5
The graph shows c ≈ 1.855. If a is more than that and decreasing, area is increasing. The sign of dA/dt will be positive. (Compare to D)
D. Units are not shown. Numerical value is correct.
Answer:
cross-section
Step-by-step explanation:
It means that if you cut through a prism, on either side you would see the same 2d shape.
R-199=70
remember you can do anything to an equaton as long as you do it to both sides
r-119=70
add 119 to both sides
r+119-119=119+70
r+0=189
r=189
