Answer:
Maximum possible error volume
Maximum possible error surface
Relative error volume
0.04
Relative error surface
0.0266
% error volume
4%
% error surface
2.66%
Step-by-step explanation:
Let's call x the length of the edge of the cube, V its volume and S its surface.
We have x= 30 cm with a possible error of 0.4 cm
On the other hand,
and
Taking differentials
and
So, the error when estimating the volume and surface, dV, dS are
and
Where x = 30cm and dx=0.4cm
Replacing
The relatives errors are
The percentage errors are relative errors times 100%
Answer:
standard form: y = -x^2 + 15x
Complete question:
y = 2x² + 2x - 3
x = -2 -1 0 1 2
Answer:
<u>Complete table of values</u>
x: -2 -1 0 1 2
y: 1 -3 -3 1 9
Step-by-step explanation:
Given;
y = 2x² + 2x - 3
To complete the table of values of the equation above, we substitute the value of x into the given equation and solve for y.
when, x = -2
y = 2(-2)² + 2(-2) - 3
y = 8 - 4 - 3
y = 1
when x = -1
y = 2(-1)² + 2(-1) - 3
y = 2 - 2 - 3
y = -3
when x = 0
y = 2(0)² + 2(0) - 3
y = 0 - 0 - 3
y = -3
when x = 1
y = 2(1)² + 2(1) - 3
y = 2 + 2 - 3
y = 1
when x = 2
y = 2(2)² + 2(2) - 3
y = 8 + 4 - 3
y = 9
<u>Complete table</u>
x: -2 -1 0 1 2
y: 1 -3 -3 1 9
