9. What statements are NOT true about the<br> solution of the system?

Crazy boy [7]

Answer:

A, B, C, and E

Step-by-step explanation:

y = 4x - 20

8x - 2y = - 20 (divide everything by 2)

4x - y = -10

-y = -4x - 10

y = 4x - 10

4x - 10 = 4x - 20

0 $\neq$ -10

Point O is the center of the accompanying figure. Find x

geniusboy [140]

We can find x only if we know that the figure is a REGULAR octagon, i.e. an octagon with all sides equal, and all interior angles equal.

We will ASSUME that the figure is a regular octagon.

For a regular polygon, the central angle subtended by each side is equal.

The central angle is 360 degrees.

So the central angle subtended by a single side euqals

a=360 degrees / 8 sides = 45 degrees / side

Since x is the total angle subtended by three sides, so

x=3*45=135 °

webassign If a snowball melts so that its surface area decreases at a rate of 6 cm2/min, find the rate at which the diameter dec

drek231 [11]

Answer:

The answer is $\frac{3}{10\pi } cm/min$

Step-by-step explanation:

Assuming the snowball is a perfect sphere, then if A denotes the surface area and D the diameter then:

$A=4\pi r^{2} = 4\pi (\frac{D}{2} )^{2} =\pi D^{2}$

Differentiating wrt r we have:

$\frac{dA}{dD} =2\pi D$

We are told that $\frac{dA}{dt}= -6$ and we want to find $\frac{dD}{dt}$

By the chain rule we have:

$\frac{dA}{dD}=\frac{dA}{dt}.\frac{dt}{dD}=\frac{\frac{dA}{dt} }{\frac{dD}{dt} }$

∴ $2\pi D=-\frac{6}{\frac{dD}{dt} }$

∴ $\frac{dD}{dt}=-\frac{6}{2\pi D}$

When D=10 then

$\frac{dD}{dt} =-\frac{6}{10*2\pi } =-\frac{3}{10\pi }$

The sign (-) shows that the D is decreasing.
