The power absorbed by a solar panel varies directly with its area. Suppose an 8 square meter panel absorbs 8,160 watts of power.

How much power does a 12 square meter solar panel absorb?

Write them equations: 8/8160 = 12/x. What's x? 

Cross multiplying yields: 8x = 12*8160 --> 1020*12 --> x = 12240.

So the 12 square meter solar panel absorbs 12240 watts of power.

The maxwell family goes out for dinner and the price of the meal is $60 the sales tax on the meal is 7% and they also want to le
sukhopar [10]
So we start with the $60 untouched.

Then we add the tax which is $60•0.07= 4.20 that is the tax

Then add the tax to the total $60 + $4.20= $64.20

Next we must add the tip so $60•0.15= 9.

Then $64.20 + $9.00 = $73.20

Total cost of meal $73.20

Any questions? :)

Can someone help me with number 8 please? Thank you.

Answer: -4 \le x \le 5
Note: to write the domain in interval notation, you'd write [-4,5]
if you need the domain in set-builder notation, then you'd write \left\{x|x\in\mathbb{R}, \ -4\le x\le 5\right\}

------------------------------------------------------------------------------

Explanation:

The domain is the set of possible x input values. Look at the left most point (-4,-1). The x coordinate here is x = -4. This is the smallest x value allowed. The largest x value allowed is x = 5 for similar reasons, but on the other side of the graph.

So that's how I got -4 \le x \le 5 (x is between -4 and 5; inclusive of both endpoints)

Writing [-4,5] for interval notation tells us that we have an interval from -4 to 5 and we include both endpoints. The square brackets mean "include endpoint"

Writing \left\{x|x\in\mathbb{R}, \ -4\le x\le 5\right\} is the set-builder notation way of expressing the domain. The x\in\mathbb{R} portion means "x is a real number"
