Answer:

a can be anything. There are infinite solutions.

Step-by-step explanation:

$4(a+2)=8+4a$

Expand:

$4a+4\times\:2=8+4a$

$4a+8=8+4a$

Subtract 8 from both sides:

$4a+8-8=8+4a-8$

$4a=4a$

Subtract 4a from both sides:

$4a-4a=4a-4a$

$0=0$

Since both sides are equal, a has infinite solutions as no matter what value it is, it will not affect the end result of $0=0$ which is true.

The length of the top of a computer desk is 2 1/4 feet longer than it’s width. If it’s width measures y feet, express its length

Lera25 [3.4K]

Answer:

The length as an algebraic expression in y is $y + (2\frac{1}{4} )$ ft

Step-by-step explanation:

The measure of the width of the computer desk = y feet

The measure of the length of the desk = width + 2 1/4 ft

⇒Measure of Length = $y + (2\frac{1}{4} )$ ft

Hence, the length as an algebraic expression in y is $y + (2\frac{1}{4} )$ ft

Given sin theta= 6/11 and sec theta < 0, find cos theta and tan theta.

bekas [8.4K]

Answer: option a.

Step-by-step explanation:

By definition, we know that:

$cos^2(\theta)=1-sen^2(\theta)\\\\tan(\theta)=\frac{sin(\theta)}{cos(\theta)}$

Substitute $sin(\theta)=\frac{6}{11}$ into the first equation, solve for the cosine and simplify. Then, you obtain:

$cos(\theta)=\±\sqrt{1-(\frac{6}{11})^2}\\\\cos(\theta)=\±\sqrt{\frac{85}{121}}\\\\ cos(\theta)=\±\frac{\sqrt{85}}{11}$

As $sec\theta$ then $cos\theta$ :

$cos(\theta)=-\frac{\sqrt{85}}{11}$

Now we can find $tan\theta$ :

$tan\theta=\frac{\frac{6}{11}}{-\frac{\sqrt{85}}{11}}\\\\tan\theta=-\frac{6\sqrt{85}}{85}$

In polar coordinates, the axis determined by theta=0 is called ?

melisa1 [442]

In polar coordinates, the axis determined by theta=0 is called the positive x-axis or horizontal axis.

To add, in mathematics, the polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction.
