A cylinder has a base with a radius of 8 inches and a height of 15 inches. What is the volume of the cylinder? (Use π = 3.14.)

stich3 [128]

R = 8
h = 15
a = r^2 * pi
a = 64pi = 201.06 sq.in.
201.06 * 15 = 3015.9 cubic inches.

Answer:

194

Step-by-step explanation:

Recall 2 rules to solve this easily:

1. $(a+b)^2=a^2+2ab+b^2$

2. $(a-b)^2=a^2-2ab+b^2$

Now, if we let a = 7 and $b=4\sqrt{3}$ , we can say the problem is basically of the form:

$(a+b)^2 + (a-b)^2$

This can be simplified using the rules:

$(a+b)^2 + (a-b)^2\\a^2+2ab+b^2+a^2-2ab+b^2\\2a^2+2b^2$

Now we can plug the values of a and b we initially thought of (remember though $\sqrt{x} \sqrt{x} =x$ ):

$2a^2+2b^2\\2(7)^2+2(4\sqrt{3})^2\\ 2(49)+2(4\sqrt{3})(4\sqrt{3})\\98+2(4)(4)(\sqrt{3} )(\sqrt{3} )\\98+2(4)(4)(3)\\98+96 \\194$

194 is the final answer.

If f(x) = 3x – 2 and g(x) = 2x + 1, find (f - g)(x). help asap :))))

Montano1993 [528]

Answer:

$(f - g)(x) = x - 3$

Step-by-step explanation:

The notation "(f - g)(x)" means we subtract the function "g" from the function "f". The resulting expression is the answer.

So, we have:

f(x) = 3x - 2

and

g(x) = 2x + 1

Thus,

$(f - g)(x) = (3x - 2) - (2x + 1)\\(f - g)(x) = 3x - 2 -2x - 1\\(f - g)(x) = x - 3$

This expression is the correct form of "(f - g)(x)"
