The absolute error is 4 cu. in. and the relative error is 10%.
To find the absolute error, subtract the actual value from the estimate:
36 - 40 = -4
With absolute error, we ignore negative signs, so the absolute error is 4 cu. in.
To find the relative/percent error, divide the absolute error by the actual value:
4/40 = 0.1
Converting this to a percent, 0.1(100) = 10%
-4.46cm
Step-by-step explanation:
The horizontal midpoint of the page is;
The horizontal midpoint of the image is given as;
For the image to be centered, these to midpoints must be on the same point in the axis.
If we take the leftmost edge of the paper to be point zero on the axis, then, the distance accommodated by the paper is 10.795cm. The distance that goes beyond this leftmost edge is computed as;
On the axis, this is on the negative side. Therefore, the horizontal position for the left edge of the image that Joelle should use to center the image is -4.46cm.
Answer:
26.08 meters (rounded to 2 decimal places)
Step-by-step explanation:
This diagonal creates a right triangle with one leg 14m and another leg 22 m. We can use pythagorean theorem to figure out the diagonal (hypotenuse of the right triangle).
Pythagorean theorem tells us
The fence needs to be 26.08 meters (rounded to 2 decimal places)
The ratio of the smaller to the larger is given as 2:4. Another way to write this is as a fraction:
which of course you can see now will reduce to
. That's your ratio.
Answer:
C. g(x) = 4x²
Step-by-step explanation:
The general equation for a parabola is
y = ax² + bx +c
Since ƒ(x) = x², a=1, b =0, c =0
For g(x), the vertex is still at the origin, so
g(x) = ax²
The graph passes through (1,4).
Insert the coordinates of the point.
4 = a(1)²
a = 4
g(x) = 4x²
The figure below shows that the graph of g(x) = 4x² passes through the point (1, 4).
