A rectangular box with an open top has a length of x feet, a width of y feet, and a height of z feet. It costs $4.30 per square
almond37 [142]

Answer:

C=$(4.30xy+5.40(xz+yz))

Step-by-step explanation:

Surface Area of a Cuboid=2(LW+LH+HW)

Since the top is open

Surface Area = LW+2(LH+HW)

If Length = x feet,

Width =y feet

Height = z feet

Surface Area = xy+2(xz+yz)

Area of the base=xy

If it costs $4.30 per square foot to build the base

Cost of the base=Cost Per Square Foot X Area = $4.30xy

Area of the sides =2(xz+yz)

If it costs $2.70 per square foot to build the sides

Cost of the sides=Cost Per Square Foot X Area of the sides

= 2.70 X 2(xz+yz)

=5.40(xz+yz)

Cost of Constructing the Box = Cost of Constructing the Base + Cost of Constructing the Sides.

Therefore,

C=$(4.30xy+5.40(xz+yz))

The function D =25+0.3 X represents the daily dental charge D in dollars for X miles driven
Lady_Fox [76]

Answer:

See Explanation

Step-by-step explanation:

Given

D = 25 + 0.3X

The question has missing details; as what's required is not stated.

However, since it is a linear equation, possible questions could be

1. Determine the slope

2. Determine the D-intercept

3. Calculate the amount in dollars for (say) 5 miles

An equation is represented as:

D = b + mx

Where

b = D\ intercept

m = slope

By comparing: D = 25 + 0.3X to D = b + mx

b = 25 and m = 0.3

This means that the slope is 0.3 and the d intercept is 25

To get the amount for 5 miles, we substitute 5 for x in D = 25 + 0.3X

D = 25 + 0.3 * 5

D = 25 + 1.5

D = 26.5

<em>The cost of 5 miles is $26</em>

Make use of the above explanation to solve the question

Answer:

(4, - 4 )

Step-by-step explanation:

Since the dilatation is centred at the origin, multiply the original coordinates by the scale factor, that is

(1, - 1 ) → (4(1), 4(- 1)) → (4, - 4 )
