Explanation:
Divide the figure into areas for which you have a surface area formula. Use the appropriate formula for each area, then add up the results.
Formulas are available for surface areas of a cone, cylinder, sphere, pyramid, rectangular prism, and for plane shapes that are circles, ellipses, triangles, rectangles, trapezoids, and regular polygons.
Most of the figures for which you are asked to find the area will decompose to some subset of these shapes. Take care to identify the relevant dimensions of each of the constituent parts of the area, and to make sure that all parts are accounted for. Do not allow your parts of the area to overlap, unless you intend to account for that overlap by subtracting the area that is counted more than once.
Also, use your common sense. A semicircle will have half the area of a circle, for example.
In some cases, it may be expedient to compute the area of a larger figure than the one you have, then subtract the part of that area that is missing from your figure.
This problem can be solved using the formula for the annuity.
Principal amount = price of the sofa(1 + sales tax)
where
price of the sofa= $670
sales tax =7.94%
Principal amount = $723.2
solve for the amortization using the formula:
Amortization = Principal amount[(i(1+i)^n]/[(1+i)^n-1]
where
i= 11.05%/12=.92%
n= 3years x 4 payments/year=36
Principal amount = $723.20
Amortization = $23.68
Get the sum of annuity
Sum of annuity=Amortization[(1+i)^n-1]/i
Sum of annuity= $852.84
The answer is letter d. Douglas paid a total of $852.84 for the sofa.
Answer:
w || n and n ⊥ m
Step-by-step explanation:
To find out which statement is true, recall the following:
1. 2 lines are said to be parallel to each other if they do not intersect at any given point and are of the same distant apart. Parallel is denoted by ||
2. 2 lines are said to be perpendicular if both lines intersect at a right angle. It is denoted by ⊥
==>From the diagram given, we can see that w and n are of the same distant apart and they do not intersect at any given point.
Also, we can see that n and m intersect at point X to at right angle.
Therefore, we can conclude that w || n and n ⊥ m
1. (3-1) will be 3,-1
2. (-4,3) will be 4,3.
Also is that all?
