Answer: 1a. $190

b. The total cost of making 20 bracelets.

c. $350

d. The total cost of making 100 bracelets.

e. $1150

f. The total cost of making 500 bracelets.

g. 150 bracelets

h. 425 bracelets

Step-by-step explanation:

1a. C(20)=150+2(20)

    C(20)=150+40

    C(20)=$190

b. The total cost of making 20 bracelets.

c. C(100)=150+2(100)

   C(100)=150+200

   C(100)=$350

d. The total cost of making 100 bracelets.

e. C(500)=150+2(500)

   C(500)=150+1000

   C(500)=$1150

f. The total cost of making 500 bracelets.

g. 450=150+2b

   2b=300

     b=150 bracelets

h. 1000=150+2b

   2b=850

     b=425 bracelets

the table below represents the displacement of a turtle from its nest as a function of time.Part A. What is the y intercept of t
hoa [83]

Part A.

Y intercept is the coordinate (0,y), when the function has an x value of 0, it is the y intercept.

In this case:

(0,5) =

y intercept = 5

IT tells about the turtle that it starts at a nest displacement of 5 miles.

Part B

The average rate of change represents the speed .

x1=1 ,y1=27

x2=4 ,y2=93

We have to calculate the slope if the function:

\text{slope}=\text{ }\frac{y2-y1}{x2-x1}

Replace:

\text{slope}=\frac{93-27}{4-1}\text{ = }\frac{66}{3}=22

Part C.

speed = distance /time

time= distance / speed

time= 225 / 22 = 10.22 hours

The domain will be

0< x ≤ 10.22

The length of a rectangle is 6 ft longer than its width.
nasty-shy [4]

Answer:

135ft²

Step-by-step explanation:

Width = w

Length = w + 6

Perimeter = 48

Perimeter = 2(l + w)

Perimeter = 2(w + 6 + w) = 48

2(2w + 6) = 48

4w + 12 = 48

4w = 48 - 12

4w = 36

w = 36/4

width = 9

length = w + 6 = 9 + 6 = 15

Area = length × width

= 15 × 9

= 135 ft²
