Answer: 450 miles

Step-by-step explanation: we can put the info we got from the question into an equation. since the car was only rented for a day, the daily rate that was paid was $26. and $0.10 for every mile the car was driven. So we can put into the equation 71 = 26 +0.10m, where m represents miles. Now subtract 26 from both sides and we get 45 = 0.10m. Divide both sides by 0.10 and we get m= 450

Second equation Answer: [tex]y=-\frac{1}{2}x-1[/tex]

First equation Answer: [tex]y=-\frac{4}{3}x~+\frac{7}{3}[/tex]

Step-by-step explanation:

Concept:

The general equation of a line in slope-intercept form is given below as

[tex]y=mx+c[/tex]

where

[tex]m=slope[/tex]

[tex]c=intercept[/tex]

The first equation is given below as

[tex]4x+3y=7[/tex]

We will make y the subject of the formula to change the equation in slope-intercept form

[tex]4x+3y=7[/tex]

subtract 4x from both sides

[tex]4x-4x+3y=7=-4x[/tex]

[tex]3y=-4+7[/tex]

divide both sides by 3

[tex]\frac{3}{y} =\frac{-4x}{3} +\frac{7}{3}[/tex]

[tex]y=-\frac{4}{3}x~+\frac{7}{3}[/tex]

Hence,

The equation of 4x+3y=7 in slope intercept form is given below as

The second equation is given below as

Hence,

The equation of x+2y=-2 in slope-intercept form is

Answer:

16

Step-by-step explanation:

16: 16=4^2 and is even. 16/2=8

30: 30 is even, 30/2=15. However, the square root of 30 is between 5 and 6([tex]\sqrt{25}[/tex]and [tex]\sqrt{36}[/tex]).

81: 81=9^2, but 81 is not even. 81/2=40.5.

99: 99 is not even and doesn't have a square root. The square root of 100 is 10, so the square root of 99 is around 9.9, slightly less than 10.

The time it would take to drive to the beach if you leave from the friend's house is 1 hour 12 minutes

From the question,  we are to calculate how long it would take to drive to the beach if you leave from your friend's house

From the given information,

The beach is 80 miles from your house and the drive takes about 1 hour 30 minutes

Distance, d, varies directly with time, t.

d ∝ t

d = vt

Where v is the proportionality constant.

Now, we will find v

d = 80 miles

t = 1.5 hours = 3/2 hours

Thus,

80 = (3/2)v

v = (2 × 80)/3

v = 160/3 miles/hour

Now, we will determine t when d is 64 miles

d = vt

64 = 160/3 × t

t = (64 × 3)/160

t = 192/160 hours

t = 6/5 hours

t = 1 hour 12 minutes

Hence, the time it would take to drive to the beach if you leave from the friend's house is 1 hour 12 minutes

The function C(x) that represents the cost of a pizza with at least one topping, where x is the number of toppings is C(x) = 9.99 + 1.25x

The domain is x >= 0 and the range is c(x) >= 9.99

The given parameters are:

One topping = 9.99

Additional topping = 1.25 each

We have x to represent the number of toppings

This means that

C(x) = One topping + Additional topping  * x

So, we have

C(x) = 9.99 + 1.25x

We have

C(x) = 9.99 + 1.25x

The smallest number of topping is 0

So, the domain is x >= 0

Substitute 0 for x in C(x) = 9.99 + 1.25x

C(0) = 9.99 + 1.25(0)

This gives

C(0) = 9.99

So, the range is c(x) >= 9.99

Answer:
C(x) = 8.74 + 1.25x

Domain: 1 ≤ x ≤ 10

Range: [9.99, 21.24]

Step-by-step explanation:

a) We need to find the function C(x) that represents the cost of a pizza with at least one topping, where x is the number of toppings.

We know that a pizza with one topping is $9.99 and that you can add additional toppings for 1.25 each.

So the equation is C(x) = 9.99 + 1.25x right?

Not really... Since $9.99 is the price of a pizza and 1 topping, we need to subtract 1 from x otherwise we would be paying for a pizza with 2 toppings when we had ordered a pizza with 1!

So the new equation is:

    C(x) = 9.99 +1.25(x - 1)

or, C(x) = 9.99 + 1.25x - 1.25

or, C(x) = 1.25x + 8.74  

b) We need to find the Domain of C(x).

We know that the pizzeria's menu lists 10 different toppings and that a pizza has at least one topping.

So we can choose up to 10 different toppings. And we need at least 1 topping.

∴ Domain is 1 ≤ x ≤ 10.

b) We need to find the Range of C(x).

We know that the domain of C(x) is 1 ≤ x ≤ 10, and that a pizza with 1 topping is $9.99.

Since we already know the minimum (9.99) all we have to do is find the maximum. We can do that by plugging in 10 into C(x) since it is the maximum of our domain.

    C(10) = 1.25(10) + 8.74

or, C(10) = 12.50 + 8.74

or, C(10) = 21.24

∴ Range of C(x) = [9.99, 21.24]

Answer:

C(x) = 8.74 + 1.25x

Domain: 1 ≤ x ≤ 10

Range: [9.99, 21.24]

The company's profit will start to decline if it only produces one bag.

Given f(x) = 2x⁴ ₋ 4x³ ₊ 7

Differentiate it with respect to x.

therefore, f'x) = 8x³ ₋ 12x²

= 4x²(2x ₋ 3)

For decreasing, f'(x) ≤ 0

⇒ 4x²(2x ₋ 3) ≤ 0

⇒ 2x ₋ 3  ≤  0

⇒ x  ≤ 3/2

Since the number of bags are represented by x.

Hence, x ∈ N

Therefore, x = 1 is only possibility.

Therefore, if the company only produces one bag, its profit begins to decline.

The value of 4²×3³×(-1)¹²² is 432.

When a number is repeatedly multiplied by itself, the result is a power of that number.

A power of the original number would be produced if you multiplied a number by itself any number of times.

When a single number is added up several times, it is said to be multiplied.

given that 4²×3³×(-1)¹²²

Based on the filing status of Brock and Erin, their itemized deductions, and their income from their salaries, their income tax liability is $4,250.

First, find the taxable income:

= Adjusted gross income - larger of Itemized deductions or standard deductions

= (50,000 + 8,000 + 5,000 + 3,000 - 2,500) - 24,800

= $38,700

The tax rate is 10 % for income between $0 and $19,750 and 12% for salaries between $19,751 and $80,250.

Brock and Erin therefore have a tax liability of:

= (10% x 19,750) + (12% x (38,700 - 19,750))

A person will take 5.88672 × [tex]10^{8}[/tex] breaths in 70 years.

Here, we are given that on average a person at rest takes approximately 16 breaths per minute.

1 hour = 60 minutes

Thus, in 1 hour a person will take-

60 × 16

= 960 breaths

Now, 1 day = 24 hours

Thus, in 1 day, a person will take-

Further, 1 year = 365 days

Thus, in 1 year, a person will take-

23,040 × 365

= 8,409,600 breaths

In 70 years, a person will take-

It will take 6.14 weeks for the plant to grow the required length

The growth rate of the plant each week = 1 1/6 inches

Converting the mixed fraction into an improper fraction we multiply the whole number by the denominator and add the numerator to get the improper fraction, therefore

The growth rate of a plant in improper form = 7/6 inches

Required growth rate = 6 1/6 inches

The required growth rate in improper fraction = 43/6 inches

Number of weeks it will take the plant to grow the required length = Required length/Growth rate each week = (43/6)/(7/6)
