Answer:

53.13 degrees

Step-by-step explanation:

From the shape of the graph, we can see that the plotted line forms a right-angled triangle with the x and y coordinates. As a result, we can use laws that govern the geometry of right-angled triangles to evaluate the solution.

$tan \theta = opposite/ adjacent$

The opposite side in this case is the side directly facing the angle Θ. This is the y - axis value = -4

The adjacent side in this case is the side above the angle Θ. This is the y - axis value = -3

$tan \theta = (-4/-3)\\\theta = tan ^-1(4/3) = 53.13 degrees$

Lets write formulas for volume of both cone and can

Cone:
Vc = Bc*Hc/3

Can:
V = B*H

where B is basis and H is height for each

Now because cone fits perfectly inside can that means that both B and H are the same
from this we can see that cone has 3 times less volume than a can that cone is inside of.

if can has 36 volume that means that cone has:
36/3 = 12 volume

Answer is 12.

Subtract, 8 3/8 - 10 1/6

IRISSAK [1]

$8\frac{3}{8} = \frac{67}{6} \\ 10\frac{1}{6} = \frac{61}{6}$

$8\frac{3}{8} - 10\frac{1}{6}$

$convert$ them to: $\frac{67}{8} - \frac{61}{6}$

$\frac{67}{8} - \frac{61}{6} = \frac{-43}{24}$

Your $answer$ : $-1\frac{19}{24}$

Good luck on your assignment & enjoy your day

Find the coordinates of a point that divides the directed line segment PQ in the ratio 5:3. A) (2, 2) B) (4, 1) C) (–6, 6) D) (4

Yuri [45]

Answer:

The answer is explained below

Step-by-step explanation:

The question is not complete we need point P and point Q.

let us assume P is at (3,1) and Q is at (-2,4)

To find the coordinate of the point that divides a line segment PQ with point P at $(x_1,y_1)$ and point Q at $(x_2,y_2)$ in the proportion a:b, we use the formula:

$x-coordinate:\\\frac{a}{a+b}(x_2-x_1)+x_1 \\\\While \ for\ y-coordinate:\\\frac{a}{a+b}(y_2-y_1)+y_1$

line segment PQ is divided in the ratio 5:3 let us assume P is at (3,1) and Q is at (-2,4). Therefore:

$x-coordinate:\\\frac{5}{5+3}(-2-3)+3 \\\\While \ for\ y-coordinate:\\\frac{5}{5+3}(4-1)+1$
