Answer:

I am not completely sure with this

Step-by-step explanation:

L restaurant=6 + M

N Restaurant= 2 x L+M

Total dumplings= 72= (6+M) + M + 2x L+M

Dumplings in N restaurant=

suppose m=2

so L= 6+M=8

so L and M will be 10=8+2

N=10 x 2= 20

so u should try and find out like that

Im in elementary school so im not sure

Which sequence could be partially defined by the recursive formula f (n + 1) = f(n) + 2.5 for n ≥ 1?

Dimas [21]

Option C: –10, –7.5, –5, –2.5, … is the sequence.

Explanation:

The given recursive formula is $f(n+1)=f(n)+2.5$ for $n\geq 1$

We need to determine the sequence.

The sequence can be determined by substituting n = 1, 2, 3, 4,....

And $f(1)=-10$

2nd term of the sequence:

Substituting n = 1 in the formula $f(n+1)=f(n)+2.5$ , we get,

$f(1+1)=f(1)+2.5$

Simplifying, we have,

$f(2)=-10+2.5=-7.5$

Thus, the 2nd term of the sequence is -7.5

3rd term of the sequence:

Substituting n = 2 in the formula $f(n+1)=f(n)+2.5$ , we get,

$f(2+1)=f(2)+2.5$

Simplifying, we have,

$f(3)=-7.5+2.5=-5$

Thus, the 3rd term of the sequence is -5

4th term of the sequence:

Substituting n = 3 in the formula $f(n+1)=f(n)+2.5$ , we get,

$f(3+1)=f(3)+2.5$

Simplifying, we have,

$f(4)=-5+2.5=-2.5$

Thus, the 4th term of the sequence is -2.5

Therefore, the sequence is –10, –7.5, –5, –2.5, …

Hence, Option C is the correct answer.

Let f(x)=x^2+x+2 and g(x)=2x^2+5. find f(g(x)). Show each step of your work. Please help me!

hodyreva [135]

Just let every x in f(x) be g(x)
it means:
f(g(x))=(2x^2+5)^2+(2x^2+5)+2
=4x^4+20x^2+25+2x^2+5+2
=4x^4+22x^2+32
