Answer:

298.5 cm^2.

Step-by-step explanation:

The area of the triangular base

= 1/2 * base * height

= 1/2 * 10 * 8.7 cm^2

There are 3 other triangular sides all withe the same area and each of them as area = 1/2 * 10 * 17

So the total surface area of the pyramid

= 1/2 * 10 * 8.7 + 3 * 1/2 * 10 * 17

= 5 * 8.7 + 3 * 85

= 298.5 cm^2.

Find an equation of the line having the given slope and containing the given point.

mart [117]

Answer:

y=8x-69

Step-by-step explanation:

you would use the equation y-y1 = m (x - x1)

plug in m = 8 , y1 = 3, x1 = 9

now you have y - 3 = 8 (x-9)

distribute 8 --> y-3 = 8x - 72

add three to both sides to get y = 8x - 69

Solve –15 = 4m – 7. –32 2 –12 –2

Shkiper50 [21]

Answer:

-2 =m

Step-by-step explanation:

–15 = 4m – 7

Add 7 to each side

–15+7 = 4m – 7+7

-8 = 4m

Divide each side by 4

-8/4 = 4m/4

-2 =m

Given a line with a slope of1/2 and a point(6,5) which lies on that find an equation to represent that line

kondor19780726 [428]

Answer:

The equation of the line is given as 2 y - x = 4.

Step-by-step explanation:

Here, the slope of the given line = 1/2

The point on the line is (x0,y0) = (6,5)

Now, by POINT SLOPE FORMULA:

The equation of line with (x0,y0) and slope m is written as:

(y - y0) = m (x-x0)

So, here the equation of line is given as

$( y- 5) = \frac{1}{2} (x-6)\\\implies 2( y-5) = ( x-6)\\or, 2y - 10 = x - 6\\\implies 2y - x = 4$

Hence the equation of the line is 2 y - x = 4.
