I don’t know how to do it can someone help me?
frozen [14]

Answer:f(g(0))= 1/5

              g(f(0))= 7

Step-by-step explanation:

for f(g(0))=you solve for g(x) but you plug in 0 for x so g(0)= 8(0)+3

                                                                                                    =3

 so now you plug in the answer of the function of g(x) witch is 3 and plug it in as the x for F(x) so f(3)= 1/(3)+2

                                     = 1/5

so f(g(0)) is equal to 1/5

Now for G(f(0)) you solve for f(x) by pluging 0 for x so F(0)= 1/(0)+2

                                                                                               =1/2

now you plug in 1/2 for the x of g(x) so g(1/2)= 8(1/2)+3

                                                                         = 4+3

                                                                         =7

so g(f(0)) is equal to 7

Hope this helps:)

marin [14]

Answer:

728

Step-by-step explanation:

2+6+18+...+486

a=2

r=6/2=3

a_{n}=ar^{n-1}\\486=2(3)^{n-1}\\3^{n-1}=486/2=243=3^5\\n-1=5\\n=5+1=6\\S_{6}=2\frac{3^6-1}{3-1} \\=2\frac{729-1}{2}\\=728

A wire is to be attached to support a telephone pole. Because of surrounding buildings, sidewalks, and​ roadways, the wire must
ad-work [718]
This situation is a right triangle with the base measuring 18 and the hypotenuse 22.  We are looking for x, the height up the pole that the wire is going to be attached to.  We will use Pythagorean's Theorem to find the missing length.  22^2-18^2=x^2  and  484-324=x^2.  x^2 = 160 so x = 4 \sqrt{10} or 12.65 feet
