The ratio of heights = ratio of the square roots of the areas because area is 2 dimensional and height is one dimensional.
so required ratio is sqrt 40pi : = sqrt40:sqrt80 = sqrt1: sqrt2 = sqrt (1/2) = 0.7071 to 4 significant figures
Answer:
Unique
Step-by-step explanation:
Let y₁ = 1 - ⁴/₃x (1)
and y₂ = ½(–x + 7) (2)
The slope of Equation (1) is -⁴/₃.
The slope of Equation (2) is -½.
The slopes are different, so there is a unique solution set.
Answer:
0
Step-by-step explanation:
Anything multiplied by 0 is 0, so since all of the numbers are being multiplied, the product has to be 0.
Answer:
Yes, he made an error in Step 3. He should have subtracted 2 from both sides.
Step-by-step explanation:
