Answer:
235.5.
Step-by-step explanation:
<u>VOLUME: THE AMOUNT OF SPACE OCCUPIED BY A 3D OBJECT.</u>
The formula for volume of a cylinder is:
The radius of this cylinder is 5 and the height is 3.
Now, we can plug the numbers in the formula.
<u>SOLVE:</u>
<u />
<u />
The product of the equation is 235.5.
I, therefore, believe the volume of this cylinder is 235.5.
This is the rule of sums of trig identities. It says that sin(a + b) = sina*cosb+sinb*cosa. Set up your right triangles. In a 30-60-90 triangle, the side across from the 60 angle is the square root of 3, the side across from the 30 is 1, and the hypotenuse is 2. In a 45-45-90 the sides across from the 45 degree angles are 1 and the hypotenuse is square root of 2. With that being said, the sin of 60 is
and the cos of 60 is 1/2. Both the sin and cos of 45 is
. So your formula is filled in like this:
. When you do the multiplication on those sets of parenthesis, you get
. When you add those your solution is
. Depending upon your instructor you may have to rationalize that denominator to get that radical out from under there, but if not, that's pretty much it!
Answer:
3x-2
Step-by-step explanation:
2x+x2-x2= 3x-2
= [(2y^13 z^4)/(4x^2)]^-1
= 4x^2/(3y^13 z^4)
