Hey there! :)
Answer:
C(-1) = -5.
Step-by-step explanation:
C(x) = -4x² + 4x + 3
Plug in -1 for x to solve for C(-1):
C(-1) = -4(-1)² + 4(-1) + 3
Simplify:
C(-1) = -4 + (-4) + 3
C(-1) = -5
Answer:
Edge length in inches = 3√(v in³)
Step-by-step explanation:
A jewelry box is shaped like a cube, with it's volume as v cubic inches.
The formula for the volume of a cube = (edge length)³
From the question, we are asked to write an expression that represents the edge length of julies jelwery box in inches
volume of a cube = (edge length)³
v in³ = edge length ³
We cube root both side
= 3√(v in³) = 3√(edge length³)
Edge length = 3√(v in³)
Therefore, the expression that represents the edge length of julies jelwery box in inches is:
Edge length in inches = 3√(v in³)
In this case we are given the mass and density and we are
to look for the volume. We know that the formula is:
volume = mass / density
Therefore calculating for volume:
volume = 50 g / (1.10 g / cm^3)
volume = 45.45 cm^3
or
<span>volume = 45.45 mL</span>
-4 because it makes it true
