Answer:
Step-by-step explanation:
2x²-3=47
2x²=47+3
x²=50/2=25
x=±√25=±5
I kind-of need more specifics here. You didn't give any dimensions, but okay. So if you notice, from the side, any cone just looks like a regular old triangle. And we can treat it like one when trying to find the slant height. Ever heard of the Pythagorean theorem? a squared plus b squared = c squared. so in this case, the hypotenuse, or c-side, will be your slant height. take the square of the distance from the circle-base's center to the apex. add that to the square of the radius of the base. Find the square root (using your calculator) of that sum, and there's your answer.
Answer:
0 and the second one
Step-by-step explanation:
integers are whole numbers they are NOT a fraction
I am not sure what the question is but here is how you use trig functions:
sine of the angle = side opposite the angle ÷ hypotenuse
cosine of the angle = side adjacent to the angle ÷ hypotenuse
tangent of the angle = side opposite the angle ÷ side adjacent to the angle
