- The Blast Off Music Company makes CDs and DVDs. The company can make a total of 500 CDs and DVDS
Phantasy [73]

Let C represent number of CDs and D represent number of DVDs.

We have been that The Blast Off Music Company can make a total of 500 CDs and DVDs each day. We can represent this information in an equation as:

C+D=500...(1)

C=500-D...(1)

We are also told that it costs $8 to make each CD, so cost of C, CDs would be 8C.

It costs $10 to make each DVD, so cost of D, DVDs would be 10D.

We have been given that the company can spend $4800 for  production costs each day. This means that cost of C CDs and D DVDs will be equal to 4800. We can represent this information in an equation as:

8C+10D=4800...(2)

Upon substituting equation (1) in equation (2), we will get:

8(500-D)+10D=4800

4000-8D+10D=4800

4000+2D=4800

4000-4000+2D=4800-4000

2D=800

\frac{2D}{2}=\frac{800}{2}

D=400

Therefore, the company can make 400 DVDs in one day.

Upon substituting D=400 in equation (1), we will get:

C=500-D \Rightarrow 500-400=100

Therefore, the company can make 100 CDs in one day.

If f(x)=ln x and g(x)=e^x+1 find f(g(2))-g(f(e)) please help!!
Readme [11.4K]

Answer:

<h3>ln (e^2 + 1) - (e+ 1)</h3>

Step-by-step explanation:

Given f(x) = ln and g(x) = e^x + 1 to get  f(g(2))-g(f(e)), we need to first find the composite function f(g(x)) and g(f(x)).

For f(g(x));

f(g(x)) = f(e^x + 1)

substitute x for e^x + 1 in f(x)

f(g(x)) = ln (e^x + 1)

f(g(2)) = ln (e^2 + 1)

For g(f(x));

g(f(x)) = g(ln x)

substitute x for ln x in g(x)

g(f(x)) =  e^lnx + 1

g(f(x)) = x+1

g(f(e)) = e+1

f(g(2))-g(f(e)) = ln (e^2 + 1) - (e+ 1)
