<span>f(x)=     3x-3 if -5 ≤ x < 3 and</span><span> x+4 if 3 ≤ x ≤ 12

Hence, f(x) is a piece wise function.

To find f(3) we will have to use x + 4 since that is the condition where x = 3 fits in.

x + 4 = 3 + 4 = 7

Hence, the answer is B.</span>

Elodia [21]

Answer:

6:5

Step-by-step explanation:

Let a be the length of the longer side of the smaller rectangle and b be the length of the shorter side of the smaller rectangle

When you look at the combined rectangle from top to bottom, you can see that 3a=l. Therefore, a=\frac{1}{3}l

This is the same for 4b=l. Thus, b=\frac{1}{4}l

When you look from right to left, you can see that w = 2b+a. Using this, we can represent w in terms of l.

w=\frac{1}{2}l+\frac{1}{3}l\\\\w=\frac{5}{6}l

Now, we can find the ratio of l:w:

l:\frac{5}{6}l\\\\1:\frac{5}{6}\\\\6:5

. Suppose that Scott and Bob live on the same street. In the winter, both of them like the snow on their street to be plowed. Bo
satela [25.4K]

Answer:

a. Using the inverse demand for each, solve for the social marginal benefit curve.

Bob:                          Scott:

Q = 40-P                    Q = 30 – P

(-1)Q – 40 = -P(-1)    (-1)Q – 30 = -2P

40 – Q = P             30 – Q = 2P

                             ((30 – Q) = 2P)/2

                            15 – 1/2Q = P

P = 15 – 1/2Q + 40 – Q

P = 55 – 1.5Q  

Scott is no longer willing to pay anything when Q >30

Social Marginal Benefit curve: Q = 40 - P

b. What is the socially efficient amount of plowing?

SMB = SMC

35 = 55 – 1.5Q

Subtract from both sides and rearrange

1.5Q = 20

Q = 13.33

c. Suppose the input costs of plowing fell and marginal costs of plowing were now constant at $5.

55 – 1.5Q = 5

55-5 = 1.5Q

50 = 1.5Q

33.3 = Q*
