Step-by-step explanation:

surface area of given figure:

l= 17

b = 11

h= 14

now curved surface area =

2 (lh +bh) +lb

= 2(17 × 14 + 11 ×14 ) + 17 ×11

= 2(238 + 154) + 187

= 2×392 + 187

= 8624 + 187

= 8811 cm^2

total surface area =

2(lb + lh + bh)

2 ( 17×11 + 17 × 14 + 11 ×14)

= 8998 cm^2

Graph this equation of a circle? I'm stuck and I don't know how to approach this math problem.

Soloha48 [4]

First use the distance formula to find the radius of the circle:
d= $\sqrt{ ( x_{2}- x_{1}) ^{2}+ ( y_{2}- y_{1}) ^{2} }$

d= $\sqrt{ (-1-23)^{2}+ (5--2)^{2} }$

d= $\sqrt{ (-24)^{2}+ (7)^{2} }$

d= $\sqrt{ (-24+7)^{2} }$

d= $\sqrt{ (-17)^{2} }$

d=|17|
d=17

Next, find the equation of the circle (use the first picture):
(x+1)^2+(y-5)^2=17^2

Finally, input the equation into a graphing calculator:

What is the slope of the line parallel to the line whose equation is y+4x=7

ryzh [129]

Y+4x =7

Or y = -4x + 7

On comparing with point slope form

y = mx+c

We get m = -4 = slope of given line

As the required line is parallel to given line its slope is equal to -4
