The graph shows a reflection in the x-axis. The matrix M such that, for any point (x, y), M(x, y) = (x', y') is

Rashid [163]

Answer:

This is a reflection about the x-axis.

Step-by-step explanation:

A reflection about the x-axis has the rule

[x,y]-> [x,-y].

Therefore

M[x,y] = [x,-y}

Let M=

|a b|

|c d|

Then the matrix multiplication gives

ax+by=x.............(1)

cx+dy=-y............(2)

Solving the previous equations (1) and (2) gives

a=1, b=0

c=0, d=-1

giving M as

|1 0|

|0 -1|

the volume of the cone is 25.12cm cubed, and the area of the base is 12.56cm squared.what is the height

Lady bird [3.3K]

Height of the cone having volume as $25.12 \text { cm}^{3}$ and base area $12.56 \text { cm}^{2}$ is 6 cm.

Solution:

Given that volume of cone = $25.12 \text{ cm}^{3}$

Area of base = $12.56 \text { cm}^{2}$

Need to determine height of the cone.

Formula for volume of the cone is as follows

$\mathrm{V}_{c}=\frac{1}{3} \pi r^{2}{h} \rightarrow (1)$

Area of circular base of cone = $A_{b}=\pi r^{2}$

Replacing $\pi r^{2} \text { by } A_{b}$ in equation (1), we get

$\mathrm{V}_{\mathrm{c}}=\frac{1}{3} \mathrm{A}_{\mathrm{b}} \mathrm{h}$

$\Rightarrow \frac{3 \mathrm{V} c}{\mathrm{A}_{\mathrm{b}}}=h$

$\Rightarrow h=\frac{3 \mathrm{v} c}{\mathrm{A}_{\mathrm{b}}} \rightarrow (2)$

In our case Volume of cone $V_c= 21.12 \text{ cm}^3$ and Area of base $A_b=12.56 \text { cm}^2$

On substituting the values of volume and area in equation 2 we get

$h=\frac{3 \times 25.12}{12.56}=6 \text{ cm }$
