Ok here you all you need to find is you equation hinting towards the points stated on the graph. Graphing has never been my strong suit, but I can assure that your answer would be:

The coordinates A(0, 0), B(0, 5) and C(3, 0) are graphed and connected together. What 3-dimensional shape will be created when t

Free_Kalibri [48]

Answer:

The 3-dimensional shape created will be a cone

Step-by-step explanation:

step 1

Plot the points

we have

A(0, 0), B(0, 5) and C(3, 0)

The figure is a right triangle

see the attached figure

When this shape is rotated about the y-axis, the 3-dimensional shape created will be a cone

where

AC is the radius of the base of cone

The radius is equal to r=AC=3 units

AB is the height of the cone

The height is h=AB=5 units

BC is the slant height of the cone

Applying Pythagoras Theorem

$BC^{2} =AB^{2} +AC^{2}$

$BC^{2} =5^{2} +3^{2}$

$BC^{2} =34$

$BC=\sqrt{34}\ units$

Coordinates (x, y)
Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (17, -12)

Point (17, 8)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{-12-8}{17-17}$
[Fraction - Denominator] Subtract: $\displaystyle m=\frac{-12-8}{0}$

We cannot divide anything by 0.

∴ Our slope m is undefined and it would be a vertical line if graphed.

write y=-3/4x+1/3 in standard form using integers. Please help I am not really understanding how to do this.

Alex17521 [72]

A line in standard form is written as:
Ax + By = C

Multiply y = 3/4x + 1/3 on both sides by 12.

This gives 12y = 9x + 4 or
9x - 12y = -4 and
9x + (-12)y = -4 are the equation written in
srandard form.
