Answer:

None of these

Step-by-step explanation:

A perpendicular bisector is a segment which intersects a given segment at a 90° angle, and passes through the given segment's midpoint. Since point T divides segment SU into two parts with lengths 46 and 62 units, VT is not a perpendicular bisector.

A median of the triangle is a segment joining a vertex to the midpoint of the opposite side. Since point T divides segment SU into two parts with lengths 46 and 62 units, VT is not a median.

An altitude of the triangle is a segment passing through a vertex and perpendicular to (i.e., forming a right angle with) a line containing the base (the side opposite the vertex). The diagram doesn't show the right angle at point T (VT is not perpendicular to SU), then VT is not an altitude.

Thus, option None of These is true.

A cone has a radius of 10 cm and and height of 9 cm. What is the approximate volume of the cone? Use 3.14 for π.

astraxan [27]

Answer:

The volume of the cone is $942cm^3$

Step-by-step explanation:

The given cone has a radius of 10 cm and and height of 9 cm.

The volume of a cone is given by:

$V=\frac{\pi r^2h}{3}$

We substitute r=10 and h=9 , $\pi=3.14$ to obtain:

$V=\frac{3.14*10^2*9}{3}$

Simplify exponents to get:

$V=\frac{3.14*100*9}{3}$

Simplify:

$V=314*3\\V=942cm^3$

Therefore the volume of the cone is $942cm^3$

what is the slope intercept form of the linear equation with a graph that passes through (-2,2) and is perpendicular to the grap

qwelly [4]

Hey there!!

Steps to get into equation which is perpendicular:

Change the slope

The slope of a perpendicular line is always negative reciprocal.

Take the point and get that into point-slope form.

y - y = m ( x - x )

Convert this equation into slope-intercept form.

'm' is the slope.

We have the slope as 1/3

The perpendicular slope would be -3.

Point slope:

The point = (-2,2)

y - 2 = -3( x - (-2) )

y - 2 = -3(x+2)

y - 2 = -3x -6

Adding 2 on both sides:

y = -3x - 4

Hence, the equation would be :

y = -3x - 4

Hope it helps!
