It assists in determining the grocery costs for items such as fruits. Functions, as mathematical expressions, reveal relationships between one or more variables. For instance, if a young girl intends to purchase 20 oranges, the price can be expressed using a function where y represents the total cost, 20 stands for the orange count, and x indicates the cost per orange, assumed to be $0.99. Consequently, the total cost amounts to $19.8 (20*0.99).

P varies inversely with x. If P = 14 when x= 16, find the value of P when x = 21.
tester [12383]

Answer:

Option C. 32/3

Step-by-step explanation:

It is understood that

A relationship between two variables, x and y, signifies inverse variation if it can be represented as either p*x=k or p=k/x

It is also known that

For p=14, x=16

Determine the value of k

k=p*x

By substituting these values

k=(14)*(16)=224

This shows that

The equation equals

p=\frac{224}{x}

Calculate the value of p when x=21

Substitute the given value of x into the equation

p=\frac{224}{21}

Simplify

Divide both the numerator and denominator by 7

p=\frac{32}{3}

A company purchased a delivery van for $28,000 with a salvage value of $3,000 on September 1, Year 1. It has an estimated useful
Svet_ta [12734]

Response:

Depreciation as of December 31, Year 1 will amount to $1,250

Detailed explanation:

Cost of Purchase = $28,000

Salvage Value = $3,000

Total Depreciation:

The total depreciation over 5 years (60 months) is calculated as Purchasing Cost minus Salvage Value

Total Depreciation over 5 years (60 months) = 28,000 - 3,000

Total Depreciation over 5 years (60 months) equals $25,000

Calculating Monthly Depreciation:

Monthly depreciation is derived from the overall depreciation divided by the total number of months as follows:

Total Depreciation for a single month = 25,000/60

Depreciation per month = 416.67$ (Monthly Depreciation)

Depreciation until December 31, Year 1

As this spans from September 1 to December 31 of Year 1, three months have passed, yielding total depreciation = 3 * Monthly Depreciation

Thus, Depreciation as of December 31, Year 1 = 3 * 416.67

Total Depreciation by December 31, Year 1 = $1,250

The curvature of the Tacoma Narrows Bridge in
tester [12383]

Response:

The width of the arch measures 105 meters

Detailed explanation:

The function that describes the width of the arch is

f(x) = -0.016(x - 52.5)² + 45

where x denotes the horizontal distance from the left end of the arch or the width at its base

f(x) indicates the vertical height of the arch

According to the given quadratic equation, the vertex coordinates of the parabola are (52.5, 45).

The vertex coordinates indicate that

the arch's height is 45 meters

and half the horizontal span from the left end is 52.5 meters

Therefore, the bridge's total width is calculated as 2 times the half span from the left side, which is 2 × 52.5

resulting in 105 meters

Consequently, the bridge's width is 105 meters.

How do you solve m=10x-x for x
lawyer [12517]
<span>m=10x-x for x
begin by taking x away from 10x

m=9x
then divide each side by 9

m/9=x

therefore, x=m/9</span>
