Answer:

See below

Step-by-step explanation:

to find the slope of a line you need to use the formula y1-y2/x1-x2

2. the points are (3,2) and (1,-2)

y1-y2 = 2--2 = 4

x1-x2 = 3-1 = 2

4/2 is the same as 2

3. (1,4) and (2,1)

4-1=3

1-2=-1

3/-1 = -3

the slope is -3

4. (6,5) and (3,1)

5-1 = 4

6-3 = 3

4/3

the slope is 4/3

The roof of a new sports arena rests on round concrete pillars. The maximum load a cylindrical column of a circular cross sectio

KATRIN_1 [288]

Answer: There are 3.5 metric tons will be supported by a column 8 m high and two thirds m in diameter.

Step-by-step explanation:

Since we have given that

Height of columns of arena = 9 m

Diameter = 1 m

Load = 14 metric tons

Since Load is directly varies as the fourth power of the diameter 'd', and inversely as the square of the height.

so, Mathematically, it is expressed as

$L=\dfrac{kd^4}{h^2}\\\\14=\dfrac{1.k}{9^2}\\\\14\times 81=k\\\\k=1134$

If the height of columns = 8 m

Diameter = $\dfrac{2}{3}\ m$

So, Load would be

$L=\dfrac{1134\times (\dfrac{2}{3})^4}{8^2}\\\\L=3.5\ tons$

Hence, there are 3.5 metric tons will be supported by a column 8 m high and two thirds m in diameter.

B) 2(5x - 6) = 3(3x + 1)

Sedaia [141]

Answer:

if you are finding x,

x = 15

Step-by-step explanation:

2(5x-6) = 3(3x+1)

10x - 12 = 9x + 3

10x = 9x + 15

x = 15

Please help me find the area of this shape

Sloan [31]

Answer:

73.5 cm²

Step-by-step explanation:

Find the area of the rectangle:

A = (3 + 12)*7 = 15*7 = 105 cm²

Find the area of triangles:

A = 1/2(3 + 15 - 9)*7 = 1/2*9*7 = 31.5 cm²

Find the shaded area:

A = 105 - 31.5 = 73.5 cm²
