First, you add up all the prices. 1.79 + 2.99 + 4.37 + 0.33 = 9.48. Then, you do 10.00 - 9.48 = 0.52 and that's your answer.

Well you would spend $9.48 meaning that you would have $0.52 cents change left.

Working Out -
$1.79 + $2.99 + $4.37 + $0.33 = $9.48. $10 - $9.48 = $0.52

Evaluate the piecewise function for the given values.

adoni [48]

Answer:

f(-3) = -2

f(-2.6) = -2

f(0.6) = 2.4

f(4.5) = 8.5

Step-by-step explanation:

(Whole question:

Evaluate the piecewise function for the given values.

Find f(-3), f(-2,6), f(0.6), and f(4.5) for f(x)={ -2 If x ≤ 0 4x. If 0 <x <1. x + 4. If x ≥ 1)

As the piecewise function shows, the function f(x) has the value of -2 for values of x lesser or equal than 0, has the value of 4x if the value of x is between 0 and 1, and has the value of x+4 for values of x greater or equal than 1.

So, for f(-3), the value of x is lesser than 0, so we have that f(-3) = -2

For f(-2.6), the value of x is lesser than 0, so we have that f(-3) = -2

For f(0.6), the value of x is between 0 and 1, so we have that f(0.6) = 4*0.6 = 2.4

For f(4.5), the value of x is greater than 1, so we have that f(4.5) = 4.5 + 4 = 8.5

A sailboat depreciates at 15% of its original value each year. If the sailboat was $9500 at its time of purchase, what is the va

eimsori [14]

Answer: After 7 years, the value of the sailboat is $3045.49.

Step-by-step explanation:

Since we have given that

Original value of the sailboat = $9500

Depreciation rate = 15%

Number of years = 7

As we know the formula for "Compound Interest "i.e

$A=P(1-\frac{r}{100})^n$

where,

A denotes Amount

P denotes original value

r denotes rate of depreciation,

n denotes number of years.

So, our equation becomes ,

$A=9500(1-\frac{15}{100})^7\\\\A=9500(1-0.15)^7\\\\A=9500(0.85)^7\\\\A=\$3045.49$

Hence, after 7 years, the value of the sailboat is $3045.49.

F(x)=3x-4; g(x)=2x+2; find g(f(x))

bekas [8.4K]

Answer:

6(x) - 6

Explanation:

g(x) = 2(x) + 2

f(x) = 3(x) - 4

<u>go from right to left in such function questions.</u>

g(f(x)):

g(3(x) - 4)

2(3(x) - 4) + 2

6(x) - 8 + 2

6(x) - 6
