12) the radius is 15 so with the equation (3.14)*r^2, we get (3.14)(15^2)=706.5
13) true, true (if x=4), true
14) y=0.75x+4.50, $8.25
Hello!
There is a discount of 40%, which means that we will be subtracting 40% of the price, and then sales tax is basically additional money added to the price, so we will be adding that.
65.00 * 40% = 26
65.00 - 26 = 39
So, the discounted price is $39. Now we must add tax on that.
39 * 5% = 1.95
39 + 1.95 = 40.95
The final price of the jacket is $40.95.
<span> Put the values of above points in the equation of straight </span>line<span> point-</span>slope<span> form m=(y2-y1)/(x2-x1) m=(-</span>5-(-10))/(-1-5) m=(-5+10)/(-6) m=5/-6 m=-5<span>/6. </span>Slope of the line<span> = m = -</span>5<span>/6 so the answer is 5/6</span>

because it never goes BELOW which is why you put the sign
The simplified answer is 27m^2
