What is the square root of -15

Final answer:

Jim can rent the car for a maximum of 4 whole days with his budget of $115, as the inequality 21d + 0.10(250) <= 115 reveals that he doesn't have enough funds to cover the fifth day.

Explanation:

To determine the maximum number of days Jim can rent a car, we can set up an inequality. The cost per day to rent the car is $21.00, and he will be charged $0.10 for every mile he drives. Jim will travel 250 miles in total. Jim has a budget of $115.00 to spend.

Let d represent the number of days Jim can rent the car for. The inequality would be:

21d + 0.10(250) ≤ 115

To solve for d, you would perform the following steps:

Solving the inequality:

21d ≤ 90

d ≤ 90 / 21

d ≤ 4.2857

Since Jim can only rent the car for a whole number of days, the maximum number of days he can rent the car is 4 days.

Therefore, Jim's belief that he can rent the car for a maximum of 5 whole days is incorrect because he does not have sufficient funds for the fifth day.

Answer:

[tex]y = 140000(1.04)^{x}[/tex]; 262 000

Step-by-step explanation:

The general formula for an exponential function is

[tex]y = a(b)^{x}[/tex]

a = 140 000; b = 1.04; x = 16

[tex]y = 140000(1.04)^{x}[/tex]

y = 140 000(1.04)¹⁶

y = 140 000 × 1.873

y = 262 000

The graph below shows the population growth over time.

Final answer:

An exponential function to model the population growth is P(t) = P_0 * e^{rt}, where the initial population P_0 is 140,000, the rate of growth r is 0.04, and the time t is 16 years. The population after 16 years is calculated by P(16) = 140,000 * e^{0.64}.

Explanation:

To model the population growth, we can use the formula for exponential growth which is P(t) = P_0 e^{rt}, where:

P(t) is the future population after time t,

P_0 is the initial population size,

e is the base of natural logarithms (approximately equal to 2.71828),

r is the rate of growth (expressed as a decimal), and

t is the time in years.

In the given situation, the initial population P_0 is 140,000, the growth rate r is 4% per year which is 0.04 when expressed as a decimal, and the time period t is 16 years. Plugging these values into the formula:

P(16) = 140,000 * e^{0.04 * 16}

To calculate the future population after 16 years, solve the equation:

P(16) = 140,000 * e^{0.64}

Using a calculator to compute e^{0.64}, and then multiplying by 140,000, we obtain the future population.

Answer:

The total pennies in Russell's collection dated after 2000 is 800

Step-by-step explanation:

Given

Total Pennies: 1,200

Pennies before 1980: 25%

Pennies between 1980 and 2000: 35%

Required

Number of pennies in Russell’s collection are dated after 2000

Let P1 represent pennies dated before 1980

Let P2 represent pennies dated between 1980 and 2000

Let P3 represent pennies dated after 2000

To calculate the number of pennies dated after 2,000. you have to understand that his total collection of pennies is 100%

This means that

P1 + P2 + P3 = 100%

Where P1 = 25% and P2 = 35%.

So, we're solving for P3

By substituting, P1 = 25% and P2 = 35%, we have

25% + 35% + P3 = 100%

60% + P3 = 100%

Make P3 the subject of formula

P3 = 100% - 60%

P3 = 40%

The quantity of pennies dated after 2,000 is then calculated by P3 * Total.

i.e. 40% * 2000

= 0.4 * 2000

= 800

Hence, the total pennies in Russell's collection dated after 2000 is 800

Answer:

18.1 million

Step-by-step explanation:

12.1 - 4.9 = 7.2 million increase in 6 years

7.2 / 6 = increase of 1.2 million a year

1.2 x 5 years = 6 million

12.1 million + 6 million = sales of 18.1 million in 2001

Based on linear growth from 1990 to 1996, ABC Electronics can expect total sales of approximately $18.1 million in 2001.

To predict sales for ABC Electronics in 2001 based on a linear growth pattern from 1990 to 1996, we first calculate the annual increase in sales over that period. In 1990, sales were $4.9 million and in 1996, sales were $12.1 million. This is an increase of $12.1 million - $4.9 million = $7.2 million over 6 years, which gives us an annual increase of $7.2 million / 6 years = $1.2 million per year.

Since we're assuming linear growth, we can extend this annual increase to predict sales for subsequent years. From 1996 to 2001 is 5 years, so we calculate the expected sales for 2001 by adding 5 times the annual increase to the 1996 sales figures: $12.1 million + (5 × $1.2 million) = $12.1 million + $6.0 million = $18.1 million.

Therefore, we can expect ABC Electronics to have total sales of approximately $18.1 million in the year 2001 if the linear growth trend continues.

Step-by-step explanation:

using the distributive property, you would multiply both the w and the 8 by 9 to obtain 9*w and 9*8. 9*w + 9*8 = 9w + 72.

This works because if you have 9 of (w+8), you have 9 w's and 9 8's. Adding these up is simply multiplying 9 by w (since there are 9 w's) and 9 by 8 (since there are 9 8's).

Answer:

$16

Step-by-step explanation:

A dozen is equal to 12 eggs. In order to find the amount for 50 eggs, we need to find the unit rate. In this problem, we can assume that each of the eggs cost the same amount.  Therefore, we can divide 3.84 by 12 to get the amount of one egg.

3.84/12= 0.32

Now that we have found the unit rate, we simply have to multiply it by 50 to get the cost. To explain why we do this, I will set it up as a proportion.

3.84/1 = ?/50

In order to get the equivalent amount you must multiply by 50.  

0.32 x 50= 16

Therefore, the answer is $16

The cost of 50 eggs is $16.

Given that, a dozen eggs cost $3.84.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Here, the cost of one egg = 3.84/12

= $0.32

Now, the cost of 50 eggs

= 50 × 0.32

= 16

Therefore, the cost of 50 eggs is $16.

Answer: u = -4w + 9

Step-by-step explanation:

u - 5 = -4(w - 1)

u - 5 = -4w + 4

  +5           +5  

u         = -4w + 9

The proper formula to solve the equation u - 5 = -4(w - 1) for w is w = (u + 9) / 4, after rearranging and simplifying the terms of the equation.

The question involves solving a linear equation with variables u and w. Initially, we have the equation u - 5 = -4(w - 1). To solve for w, we need to isolate w on one side of the equation. A statement in the information provided seems to mistakenly give the result of w, which probably arises from a typo or error, stating w = -40 - 5. However, this is incorrect given the initial equation.

Let's start by expanding the right side of the initial equation:

And then rearranging to solve for w:

From this process, we see that the correct formula to isolate and solve for w is w = (u + 9) / 4.

Answer:

They will meet at 3836 meters

Step-by-step explanation:

Maya is at 7832 meters

Juan is at -160 meters  ( below sea level)

If they are meeting at the midpoint, we add them together and divide by 2

Midpoint = (7832 + -160)/2

               = (7672)/2

               =3836 m

Answer:

The midpoint elevation will be 3,836 meters.

Step-by-step explanation:

Maya's elevation of 7832 can be represented by the positive integer +7832 since she is above sea level.  Sea level would represent 0 on our number line.  However, Juan is below sea level, so we can represent his distance at -160.  When we add these two integers together +7832 + (-160) = 7672 meters above sea level.  Since Maya and Juan are going to meet at the midpoint, we would divide our overall distance (7672) by two to get 3836 meters.

Answer: 81, 27, 9, 3, 1, 1/3

There are six terms listed. The first five are whole numbers and the sixth term is a fraction.

==============================================

Explanation:

The equation t1 = 81 means that the first term "t" is 81. The second term is t2 = 27 because we multiply 1/3 by 81, or divide 81 over 3, and we end up with 81/3 = 27 as the second term.

We know to multiply by 1/3 because of the equation tn = (1/3)*t_(n-1) where the "n-1" portion is smaller than 't'. We can write it like this[tex]t_n = \frac{1}{3}*t_{n-1}[/tex]

To get the next term, we multiply by 1/3 again: 27*(1/3) = 27/3 = 9 giving us the third term

And repeat until we have six terms

9*(1/3) = 9/3 = 3 is the fourth term

3*(1/3) = 3/3 = 1 is the fifth term

1*(1/3) = 1/3 is the sixth term

So that is how I got the first six terms to be 81, 27, 9, 3, 1, 1/3
