Answer:

The equation of line parallel to given line passing through (8,-7) is:

y = -\frac{5}{4}x+3

Step-by-step explanation:

Given line is:

5x+4y=16

first of all, we have to convert the equation of given line in slope-intercept form

4y = -5x+16

Dividing both sides by 4

\frac{4y}{4} = -\frac{5x}{4} + \frac{16}{4}\\y = -\frac{5}{4}x+4

Slope intercept form is:

y=mx+b

The slope of given line is:

m = -\frac{5}{4}

Let m1 be the slope of line parallel to given line

"The slopes of two parallel lines are equal"

m = m_1\\m_1 = -\frac{5}{4}

The equation of line parallel to given line will be:

y = m_1x+b

Putting the value of slope

y = -\frac{5}{4}x+b

Putting the point (8,-7) in the equation

-7 = -\frac{5}{4}(8)+b\\-7 = -(5)(2) + b\\-7 = -10+b\\b = -7 +10\\b = 3

Putting the value of b

y = -\frac{5}{4}x+3

Hence,

The equation of line parallel to given line passing through (8,-7) is:

y = -\frac{5}{4}x+3

Line of symmetry is the line which cuts the figure into two same halves

or we can say that which passes through the figure such that it makes one half the mirror image of the other half

So we can see from the figure that y=-2 is the line which cuts the figure in to equal halves

So

y=-2

We have a bunch of rectangles making up the lateral sides of this figure. They have side length 12 and height 13.

So the area of one rectangle is 12 x 13 = 156.
We have 6 of these rectangles, so our lateral area is 6(156) = 936.

The total surface area requires that we include the area of the base. To find the area of a regular polygon we take half of the product of the apothem and perimeter.

A = (1/2)*a*p

The apothem is given to be 10.39,
and the perimeter is fairly easy to calculate:
With the side length being 12, the perimeter is then 6(12) = 72.

So then the area of our base is (1/2)*10.39*72 = 374.04

So then the total surface area is the (base area) + (lateral area),
374.04 + 936 = 1310.04

Alika [10]

Answer:

D

Step-by-step explanation:

379.00 - 15.00 + 154.00 x 3 + 65.00 + 13.00 = 904

0.55 x 63 = 34.65

34.65 + 904 = 938.65
