Answer:

Step-by-step explanation:

If you're asking for the equation of a line that goes through (1,-5) and is perpendicular to y=18x+26 here's what you do.

1. find the slope of the new line by taking the negative reciprocal of the slope of the first line ( $-\frac{1}{18}$ )

2. plug in the point (1,-5) and the new slope into the point slope form equation

$y_{2} -y_{1}=m(x_{2}-x_{1})$

3.Now that you have y-(-5)= -1/18(x-1) simplify

3.a y-(-5)= -1/18x + 1/18

3.b y=-1/18x - 89/18

4. final equation you get is y = -1/18 - 89/18

A silo is not the shape of a cone. The silo is 8 meters tall and it's base has a diameter of 3 meters. Soybeans cost $414 per cu

Gnom [1K]

Answer:

$7803.72

Step-by-step explanation:

We have been given that a silo is in the shape of a cone. The silo is 8 meters tall and it's base has a diameter of 3 meters. Soybeans cost $414 per cubic meter. We are asked to find the total cost to fill the silo with soybeans.

First of all, we will find the volume of silo using volume of cone formula.

$\text{Volume of cone}=\frac{1}{3}\pi r^2 h$ , where,

r = radius

h = Height

We know that radius is half the diameter, so radius of silo would be $r=\frac{3}{2}=1.5$ .

$\text{Volume of cone}=\frac{1}{3}\pi (1.5\text{ m})^2 (8)\text{ m}$

$\text{Volume of cone}=\frac{1}{3}\pi\times 2.25\text{ m}^2 (8)\text{ m}$

$\text{Volume of cone}=\pi\times 0.75\text{ m}^2 (8)\text{ m}$

$\text{Volume of cone}=\pi\times 6\text{ m}^3$

$\text{Volume of cone}=18.8495559\text{ m}^3$

Now we will multiply total volume by $414 to find total cost.\

$\text{Total cost of soybeans}=\$414 \times 18.8495559$

$\text{Total cost of soybeans}=\$7803.7161426$

$\text{Total cost of soybeans}\approx \$7803.72$

Therefore, it will cost $7803.72 to fill the silo with soybeans.

if the following line segment is reflected across the x-axis what are the coordinates new endpoints A.) (-1,-6) and (-3,-2) B.)

Tasya [4]

Answer:

A.) (-1,-6) and (-3,-2)

Step-by-step explanation:

The given line segment has coordinates

(-1,6) and (-3,2)

The mapping for a reflection in the x-axis is

$(x,y)\to (x,-y)$

This implies that;

$(-1,6)\to (-1,-6)$

and

$(-3,2)\to (-3,-2)$

The correct choice is A.

PPPLLLLEEEAASSSEEEE HHHEEEELLLLPPPPP!!!!!!!

Yuliya22 [10]

Answer:

(3, 3) × 13 = (39, 39)

(0, 3) × 13 = (0, 39)

(6, -6) × 13 = (78, -78)

(9, 6) × 13 = (117, 78)

Step-by-step explanation:

Because the center of dilation is at (0, 0), or the origin, we can just multiply the x and y values of each point by the scale factor of 13.

(3, 3) × 13 = (39, 39)

(0, 3) × 13 = (0, 39)

(6, -6) × 13 = (78, -78)

(9, 6) × 13 = (117, 78)

Which angles are supplementary to each other?

Rus_ich [418]

Answer:

Angle 4 and Angle 1 are supplementary to each other.

Step-by-step explanation:

A line is 180°. Because angle 4 and angle 1 and right next to each other and they share a straight line, both of their angles should add up to 180°, making these two angles supplementary.
