12 cm for the first one and 11.6 for the second.
Unrelated to the question, that house around number 3 gives me nostalgia of elementary school :)
So the ryder is building a workbench and the top of the workbench is a rectangular piece
Answer:
k = -8c.
Step-by-step explanation:
y^2 = kx
Find the slope of the tangent by differentiating:
y' 2y = k
y' = k / 2y = the slope of the tangent.
The given equation of the tangent is y = -2x + c so the slope = -2.
Therefore k/2y = -2 so k = -4y and y = -k/4
y^2 = kx so k^2/16 = kx giving x = k/16.
Substituting for x and y in y = -2x + c:
-k/4 = -2 k/16 + c
-k/4 = -k/8 + c
c = -k/4 + k/8 = -k/8.
So -k = 8c
k = -8c.
Mary has 10 yards She used 2 yards:
She sis left with 10 - 2 = 8 yards
She want to cut the rest at 1/3 yard long,
8÷ 1/3 = 8 x 3 = 24 pieces
Answer:
4.31
Step-by-step explanation:
Find the cube root of both sides of the equation.
= 
The cube root will cancel out the cubed in the variable.
v = 
Find the cube root of 80. I rounded to the nearest hundredth.
v = 4.31
