Answer:

\boxed{\sf \ \ \ 248 \ \ \ }

Step-by-step explanation:

Hello,

(fog)(4)=f(g(4)) \ \ \ and \ \ \ g(4)=-6*4^2+9*4+9=-51 \ \ so\\(fog)(4)=f(-51)=-5*(-51)-7=255-7=248

hope this helps

Find the common difference of the arithmetic sequence, the next three terms, the equation, and the term given for 8, 10, 12, 14
fredd [130]

Answer:

see explanation

Step-by-step explanation:

In an arithmetic sequence the common difference d is

d = a₂ - a₁ = 10 - 8 = 2

To obtain the next term in the sequence add d to the previous term, that is

a₅ = 14 + 2 = 16

a₆ = 16 + 2 = 18

a₇ = 18 + 2 = 20

The next 3 terms in the sequence are 16, 18, 20

The n th term equation for an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 8 and d = 2, thus

a_{n} = 8 + 2(n - 1) = 8 + 2n - 2 = 2n + 6

12 gallons of water fill a tank of 3/4 capacity if the tank is fill full how many half gallons bottles can be filled with water
Advocard [28]
If 12= 3/4, then 16=4/4 would be a full tank.

The question is asking how many half gallon bottles can be filled, if there’s 16 full gallons, you’d multiply 16 by 2, and get 32.

Your answer is 32 half gallons

Sylvia has a piece of material that is 668.36 square inches. She marked the material into 4 equal pieces and then cut out one of
sveta [45]

The whole magic jug had 668.36 ounces of mysterious elixir in it.
Sylvia came along and marked it into 4 equal amounts, so each
amount was  (1/4)  of  (668.36 ounces).

Now, you would have us believe, she tucked the magic jug under her cloak,
walked quickly and quietly down the hall into the shadows, pulled the jug out,
and quaffed one of the equal amounts from it, all in one slug.

The quantity remaining in the jug was then 

                     (3/4) of (668.36 ounces)  =  501.27 ounces.

The same process works for length, volume, area, stones, money, anything.
If you divide up what you have into 4 equal parts, then each part is 1/4 .
If you eat, sell, lose, or give away  1/4  of it, you have  3/4  left.
