Answer:

$44.16

Step-by-step explanation:

total amount to pay = $38.40 + (0.15)($38.40)

                                 = $38.40 + 5.76

                                 = $44.16

You can also just put 38.40 * 1.15 and you will get the same answer

Determine the number of subsets and list down all of them.
Setler [38]

We have to use Powerset .All of the elements are subsets of the set.

  • If n(A)=n

\boxed{\sf P(A)=2^n}

#1

  • {a,b,c}
  • It has 2^3=8subsets

Now

P(A)={{a},{b},{c},{a,b},{a,c},{b,c},{a,b,c}}

#2

  • {2,4,6,8}
  • It has 2^4=16 subsets

Now

P(A)={{2},{4},{6},{8},{2,4},{2,8},{2,8},{4,8},{4,6},{6,8},{2,4,6},{2,4,8},{2,6,8},{4,6,8},{2,4,6,8}}

#3

It has 2^5=32 subsets

Now

P(A)={{1},{2},{3},{4},{5},{1,2},{1,3},{1,4},{1,5},{2,3},{2,4},{2,5},{3,4},{3,5},{4,5},{1,2,3},{1,2,4},{1,2,5}...{1,2,3,4,5}}

The graph of f ′ (x), the derivative of f of x, is continuous for all x and consists of five line segments as shown below. Given
ivolga24 [154]

Answer:

B

Step-by-step explanation:

f(0) - f(-3) = area under f'(x) from x=0 to x=3.

We can find the area under f'(x) in this interval by finding the area of the triangle formed by the line.

A = 1/2 b h

A = 1/2 (3) (3)

A = 4.5

f(0) - f(-3) = 4.5

Since f(0) = 7:

7 - f(-3) = 4.5

f(-3) = 7 - 4.5

f(-3) = 2.5
