A car rental company charges a one-time application fee of 40 dollars, 55 dollars per day, and 13 cents per mile for its cars. A

liberstina [14]

Answer:

A) C(d,m) = 40 + 55d + 0.13m

B) $448

Step-by-step explanation:

Let 'd' be the number of days and 'm' the number of miles driven.

A) The cost function that describes a fixed amount of $40, added to a variable amount of $55 per day (55d) and a variable amount of 13 cents per mile (0.13m) is:

$C(d,m) = 40 +55d +0.13m$

B) If d = 5 and m =600, the total cost is:

$C(5,600) = 40 +55*6 +0.13*600\\C(5,600)=\$448$

The cost is $448.

HELP! BRAINLIEST!

love history [14]

Given that,

Charge q₁ = -0.004 C

Charge q₂ = -0.003 C

Distance between charges, d = 3 m

To find,

The electrostatic force between charges.

Solution,

The formula for the electrostatic force is given by :

$F=\dfrac{kq_1q_2}{d^2}\\\\F=\dfrac{9\times 10^9\times 0.004 \times 0.003 }{(3)^2}\\\\=12000\ N$

So, 12000 N of electrostatic force is produced.

What single decimal multiplier would you use to decrease by 14% followed by a 9% decrease?

xenn [34]

Answer:

the single decimal multiplier is 0.7826

Step-by-step explanation:

The computation of the single decimal multiplier is given below:

Given that

It is reduced by 14% that followed by 9% decrease

So according to this, the following calculation is required

= (1 - 0.14) × (1 - 0.09)

= 0.86 × 0.91

= 0.7826

Hence, the single decimal multiplier is 0.7826

The side s of a square carpet is measured at 5 ft. Estimate using the Linear Approximation the maximum error in the area A of th

KonstantinChe [14]

Answer:

$0.333 ft^2$

Step-by-step explanation:

We are given that

Side of square carpet,s=5 ft

$\Delta s=0.4 in=\frac{0.4}{12}ft$

1 foot=12 in

We have to find the maximum error in the area of the carpet by using the linear approximation .

Area of square,A= $(side)^2=s^2$

$dA=2sds$

Substitute the values

$dA=2\times 5\times \frac{0.4}{12}$

$dA=0.333ft^2$

Hence, the maximum error in the area of the carpet= $0.333 ft^2$

1/2(-3/2n+1)=3/4-n<br> What does n equal

zhannawk [14.2K]

Answer:

n = 1

Step-by-step explanation:

1/2 (-3/2n + 1) = 3/4 - n

-3/4n + 1/2 = 3/4 - n

n - 3/4n = 3/4 - 1/2

1/4n = 1/4

n = 1

1/2 (-3/2(1) + 1) = 3/4 - (1)

1/2 ( -3/2 + 1) = -1/4

1/2 ( -1/2) = - 1/4

-1/4 = -1/4
