Let's put it this way: If you plot a few non-x-intercept points and then draw a curvy line through them,you will not know if you got the x-intercepts even close to being correct. <span>The only way you can be sure of your x-intercepts is to set the quadratic equal to zero and solve. So its a matter of guessing from the pictures. Basicaly said, the calculator won't give you the exact result.</span>
<u>Question</u><u> </u><u>1</u>
<u>Question</u><u> </u><u>2</u>
By the geometric mean theorem,
<u>Question</u><u> </u><u>3</u>
By the Pythagorean theorem,
<u>Question</u><u> </u><u>4</u>
By the Pythagorean theorem,
You must use the formula for calculate the surface area of a sphere, which is:
SA=4pir^2
By using the information given in the problem shown above, you have:
SA=4pir^2
r=1 inch
SA=4pi(1 inch)^2
SA=13 in^2
