A county in Alabama has a population of 90,000 people. It has an area of 800 mi2. How many people are there per square mile? A) about 72 B) about 88 C) about 113 D) about 720

Answers

Answer:

C) about 113

Step-by-step explanation:

"How many people are there per square mile?" means that we want a ratio with miles as denominator. In other words, to find the population density, we just need to divide the population by the land area (miles squared):

[tex]population-density=\frac{people}{land-area}[/tex]

We know that the population of Alabama is 90,000 people and its land area is 800 miles squared, so [tex]people=90000[/tex] and [tex]land-area=800mi^{2}[/tex].

Replacing values:

[tex]population-density=\frac{people}{land-area}[/tex]

[tex]population-density=\frac{90000}{800mi^{2}}[/tex]

[tex]population-density=112.5[/tex]

Which rounds to:

[tex]population-density=113[/tex]

We can conclude that there are approximately 113 people per square mile in Alabama.

Use the given graph to determine the limit, if it exists. Find limit as x approaches two from the left of f of x. and limit as x approaches two from the right of f of x..

Answers

By the confront theorem we know that the limit only exists if both lateral limits are equal

In this case they aren't so we don't have limit for x approaching 2, but we can find their laterals.

Approaching 2 by the left we have it on the 5 line so this limit is 5

Approaching 2 by the right we have it on the -3 line so this limit is -3

Think: it's approaching x = 2 BUT IT'S NOT 2, and we only have a different value for x = 2 which is 1, but when it's approach by the left we have the values in the 5 line and by the right in the -3 line.

ANSWER

The limit does not exist.

EXPLANATION

From the graph the left hand limit is the value the graph is approaching as x-values approaches 2.

[tex] \lim_{x \to {2}^{ - } }(f(x)) = 5[/tex]

Also the right hand limit is the value that the graph approaches, as x-values approach 2 from the right.

[tex]\lim_{x \to {2}^{ + } }(f(x)) = - 3[/tex]

Since the left hand limit is not equal to the right hand limit, the limit as x approaches 2 does not exist

for the following right triangle, find the side length of x. round your answer to the nearest hundredth.

top side: x
left side: 15
right side: 8

Answers

Answer:

17 units

Step-by-step explanation:

The sides of all right triangles share the same relationship known as the Pythagorean Theorem a² + b² = c². Substitute the lengths of the triangle into the theorem and solve for the unknown side. Since the problem does have an attached a picture, assume that a = 8, b = 15, and c = x.

8² + 15² = x²

64 + 225 = x²

289 = x²

√289 = √x²

17 = x

Final answer:

To find the length of side x in the right triangle, we use the Pythagorean theorem, which yields a hypotenuse value of 17 units. The exact value does not require rounding to the nearest hundredth.

Explanation:

To find the side length of x in a right triangle with a perpendicular side of 15 and a base of 8, we can use the Pythagorean theorem. The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Here's how you do it:

Let's call the perpendicular side a, the base b, and the hypotenuse c.

According to the theorem, we have the equation a2 + b2 = c2.

Insert the known values into the equation: 152 + 82 = c2.

Solve for c: 225 + 64 = c2, which simplifies to 289 = c2.

Take the square root of both sides to solve for c: c = √289.

Calculate the square root, which gives us c = 17.

Therefore, the length of side x (which is the hypotenuse in our case) is 17 units. We don't need to round our answer because 17 is already to the nearest hundredth.

What transformations are needed to change the parent cosine function to y=3cos(10(x-pi))?

Answers

Answer:

The graph of [tex]y=cos(x)[/tex] is:

*Stretched vertically by a factor of 3

*Compressed horizontally by a factor  [tex]\frac{1}{10}[/tex]

*Moves horizontally [tex]\pi[/tex] units to the rigth

The transformation is:

[tex]y=3f(10(x-\pi))[/tex]

Step-by-step explanation:

If  the function [tex]y=cf(h(x+b))[/tex]  represents the transformations made to the graph of [tex]y= f(x)[/tex]  then, by definition:

If  [tex]0 <c <1[/tex] then the graph is compressed vertically by a factor c.

If  [tex]|c| > 1[/tex] then the graph is stretched vertically by a factor c

If [tex]c <0[/tex]  then the graph is reflected on the x axis.

If [tex]b> 0[/tex] The graph moves horizontally b units to the left

If [tex]b <0[/tex] The graph moves horizontally b units to the rigth

If [tex]0 <h <1[/tex] the graph is stretched horizontally  by a factor [tex]\frac{1}{h}[/tex]

If [tex]h> 1[/tex] the graph is compressed horizontally by a factor [tex]\frac{1}{h}[/tex]

In this problem we have the function [tex]y=3cos(10(x-pi))[/tex] and our parent function is [tex]y = cos(x)[/tex]

The transformation is:

[tex]y=3f(10(x-\pi))[/tex]

Then [tex]c =3>1[/tex]  and [tex]b =-\pi < 0[/tex] and [tex]h=10 > 1[/tex]

Therefore the graph of [tex]y=cos(x)[/tex] is:

Stretched vertically by a factor of 3.

Also as [tex]h=10[/tex] the graph is compressed horizontally by a factor  [tex]\frac{1}{10}[/tex] .

Also, as [tex]b =-\pi < 0[/tex] The graph moves horizontally [tex]\pi[/tex] units to the rigth

A six-sided number cube is rolled five times, X is the number of times an even number is rolled.

Which statement is true about this situation?


A. The variable X does not have a binomial distribution because P(success) is not constant.

B. The variable X has a binomial distribution. P(success)=0.5; number of trials = 5

C. The variable X does not have a binomial distribution because there are more than two possible outcomes.

D. The variable X has a binomial distribution. P(success)=0.2; number of trials = 5

Answers

Step-by-step explanation:

A six sided die has three even numbers, and each roll is independent, so P(success) is constant at 3/6 = 0.5.  Since it's constant, the variable X does indeed have a binomial distribution.

So the answer is the second one, which you have selected.

Answer:

It is B.

Formula: a^2*(h/3)

We know a is 6ft, but to find h, the height, we'll need to use Pythagoreon Theorem. The hypothenuse of the triangle is 5 and one of the legs is 3, because you need to divide 6 by 2.

Answer:

Step-by-step explanation:

The angle immediately adjacent to the 29° angle is (90° - 29°) , or 61°.

The cosine function relates this 61° angle to the 500 ft hypotenuse and the unknown adjacent side y:

                    y

cos 61° = -----------

                500 ft

so that y = (500 ft)(cos 61°) =  (500 ft)(cos 61°) =  (500 ft)(0.485) = 242.4 ft

While traveling to and from a certain destination, you realized increasing your speed by 10 mph saved 1 hours on your return. If the total distance of the roundtrip was 600 miles, find the speed driven while returning.

Answers

Answer:

60 mph

Step-by-step explanation:

time = distance/speed

If s represents the return speed, then the relationships of the travel times is ...

300/(s-10)-1 = 300/s

300s -s(s-10) = 300(s-10) . . . . . multiply by s(s-10)

-s^2 +310s = 300s -3000 . . . . eliminate parentheses

s^2 -10s -3000 = 0 . . . . . . . . . . write in standard form

(s -60)(s +50) = 0 . . . . . . . . . . . . factor

This has solutions s=60, s=-50. The negative solution is extraneous.

The return speed was 60 mph.

We want to find the speed in your return given that increasing the speed by 10 mph would saved you an hour of trip.

The speed was 72.62 mi/h

We know the relationship:

distance = speed*time

Let's assume the speed is represented with the variable S, and the time it took you to return is represented with T.

We know that the distance of the roundtrip was 600 miles.

then we can write:

600mi = S*T

Now we know that if we increase the speed by 10mi/h, the time decreases by one hour, so we can also write:

600mi = (S + 10mi/h)*(T - 1h)

So we have a system of equations:

600mi = S*T600mi = (S + 10mi/h)*(T - 1h)

To solve this, we can isolate one of the variables in one of the equations and then replace that on the other equation.

I will isolate T in the first one:

T =  600mi/S

Now we replace this in the other equation to get:

600mi = (S + 10mi/h)*(600mi/S - 1h)

Now we can solve this for S, the speed.

600mi = 600mi - 1h*S + (6,000 mi^2/h)/S - 10mi

0 = -1h*S + (6,000 mi^2/h)/S - 10mi

Now we multiply both sides by S to get:

0 = -1h*S^2 + (6,000 mi^2/h) - 10mi*S

This is a quadratic equation, we can solve this byt using the Bhaskara's formula:

[tex]S = \frac{10mi \pm \sqrt{(10mi)^2 - 4*(6,000 mi^2/h)*(-1h)} }{2*(-1h)} \\\\S = \frac{ 10mi \pm 155.24mi}{-2h}[/tex]

We need to take the positive solution, so we get:

S = (10mi - 155.24 mi)/(-2h) = 72.62 mi/h

The speed was 72.62 mi/h

Answers

Answer:

The Answer is 5 (3/4) more miles.

Step-by-step explanation:

For this we just need to add and subtract fractions.

We we want  to get to 13 (1/2) miles...however we have already ran

3 (1/2) + 4 (1/4) ... this is the same as 3.5 plus 4.25. When we add those up we get...

3.5+4.25 = 7.75 then we subtract ... 13.5 - 7.75 = 5.75 = 5 (3/4) our answer.

Final answer:

Lorenz needs to run 5 3/4 more miles to meet his goal for his training plan this week.

Explanation:

To find out how many more miles Lorenz needs to run this week to meet his goal, we need to add up the miles he has already run and subtract that from his goal. Lorenz has already run 3 1/2 miles on Monday and 4 1/4 miles on Tuesday, so we can add these two amounts to get 3 1/2 + 4 1/4 = 7 3/4 miles. Next, we subtract this amount from his goal of 13 1/2 miles: 13 1/2 - 7 3/4 = 5 3/4 miles. Therefore, Lorenz needs to run 5 3/4 more miles to meet his goal for his training plan this week.
