Answer:

Plane speed: 480mph

Wind speed: 80mph

Step-by-step explanation:

Miami to Seattle: time = 7hrs

Speed (s) = 2800mph

D = speed/time = 2800/7

= 400mph

Seattle to Miami:

Same speed = 2800mp

Time = 5hrs

Distance (D) = speed/time

= 2800/5 = 560mph

Let p be speed of plane and w wind speed.

Therefore, P+w = 560. . .1

P-w = 400. . .2

2p = 960

P = 960/2 = 480

Therefore, P + w = 560

480 + w = 560

W = 80mph

While P = 480mph

The solution to system is x = 0 and y = -1

Solution:

Given system of equations are:

-8x + 2y = -2 ----------- eqn 1

4x + 4y = -4 ---------- eqn 2

We have to solve the system of equations

We can solve the equations by elimination method

Multiply eqn 2 by 2

8x + 8y = -8 ------ eqn 3

Add eqn 1 and eqn 3

-8x + 2y = -2

8x + 8y = -8

( + ) ---------------

0x + 2y + 8y = -2 - 8

10y = -10

Divide both sides by 10

y = -1

Substitute y = -1 in eqn 1

-8x + 2(-1) = -2

-8x - 2 = -2

-8x = -2 + 2

x = 0

Thus the solution to system is x = 0 and y = -1

Step-by-step explanation:

To find the circumference of a circle, use the formula C = 2πr. To find the area, use the formula A = πr^2.

The question asks to match each circular flower bed on the left to its circumference and its area on the right. In order to find the circumference of a circle, we use the formula C = 2πr, where r is the radius of the circle.

To find the area of a circle, we use the formula A = πr^2. We can use these formulas to calculate the circumference and area of each circular flower bed and match them to the options on the right.

For example, if a circular flower bed has a radius of 3 meters, we can find its circumference by plugging the radius into the formula: C = 2π(3) = 6π meters. Similarly, we can find its area by plugging the radius into the formula: A = π(3^2) = 9π square meters.

where, a =49 and b=1/7.

It is an exponential function. So, the domain is the set of all real numbers.

Since, a=49 which is a positive value, therefore the range is y>0.

The value of b is 1/7, it means as x increased by 1, each y-value is one seventh of the previous y-value.

Therefore, the correct options are 1, 4 and 5.

Final answer:

The value of 4x when x=4 is 16, and for proportions like 1:2=4:x, you'd get x=8 by cross multiplying.

Explanation:

The value of 4x when x=4 is simply 4 multiplied by 4, which equals 16. This calculation is a basic algebraic operation, and it should not be confused with more complex problems. For example, if you're trying to solve a proportion like 1:2=4:x, you'd set up a proportion to figure out the value of x. To solve for x you can use the cross multiplication method, resulting in 1x = 8, hence x = 8.

Final answer:

The value of 4x^3 + 4x when x=4 is found by substituting 4 into the expression and simplifying step by step, resulting in a final answer of 272.

Explanation:

When answering a question such as "What is the value of 4x3 + 4x when x=4," we need to substitute the value of x into the expression and simplify.

Let's break it down step-by-step:

Substitute x with 4 into the expression: 4(4)3 + 4(4).

Calculate the exponent: (4)3 = 4 x 4 x 4 = 64.

Multiply by 4: 4 x 64 = 256.

Add the second term: 256 + 4(4).

Perform the second multiplication: 4 x 4 = 16.

Add the two results together: 256 + 16.

Get the final answer: 272.

The value of 4x3 + 4x when x=4 is 272.

Answer:10,349

Step-by-step explanation:

To find out how much Tina needs to run each day, divide the total miles she wants to run by the number of days. The result is that Tina needs to run 1.8 miles each day.

To find out how far Tina must run each day, we need to divide the total distance she plans to run by the number of days she plans to run. Tina wants to run 12 3/5 miles over 7 days. As a first step, convert her mixed number to an improper fraction. 12 3/5 is equivalent to 63/5.

Now, to find the distance she must run each day, simply divide 63/5 miles by 7 days. Carrying out this division gives us distance of 9/5 miles per day, or in decimal form, 1.8 miles per day.

So, Tina should run 1.8 miles each day to reach her goal.

Step-by-step explanation:

Linear Modeling

Some situations in real life are bound to be modeled as mathematical functions. A model allows scientists and analysts to take decisions based on predicted values coming from those models.

To construct them we usually take or measure values of the variables of interest and find the general equation of the model. In this case, we'll find the relation between the service costs (y) of a cell phone provider and the number of months (x).

There are three points available: ( 1 , 72.99 ) , ( 2 , 101.44 ) , ( 3 , 129.89 ) and we only need two to find a function of the form

[tex]y=c+d(x-1)[/tex]

We'll use the first two points and use the third point to verify the validity of the model. Let's plug in the first point:

[tex]72.99=c+d(1-1)[/tex]

Operating

[tex]72.99=c\\c=72.99[/tex]

Now for the second point

[tex]101.44=72.99+d(2-1)[/tex]

Operating and rearranging

[tex]d=101.44-72.99=28.45[/tex]

Our model is complete:

[tex]\boxed{y=72.99+28.45(x-1)}[/tex]

Let's check the third point  ( 3 , 129.89 ) by plugging x=3

[tex]y=72.99+28.45(3-1)=72.99+56.9=129.89[/tex]

The point belongs to the function.

Final answer:

The cell phone provider's escalating monthly charges can be represented by a linear equation, demonstrating the initial cost plus the consistent monthly increase. The equation is y = 72.99 + 28.45(x - 1).

Explanation:

To find the equation representing the cell phone provider Talk of the Town, we observe the costs for the first three months: $72.99 for the first month, $101.44 for the second, and $129.89 for the third. The increase in cost from one month to the next is consistent, increasing by $28.45 each time. This situation can be expressed as a linear equation in the form y=c+d(x−1), where y is the total cost, c is the starting value, d is the difference per period, and x represents the month number.

To find c (the initial cost), we look at the first month's charge: $72.99. d, the monthly increase, is $28.45. Thus the equation for the total cost of service from Talk of the Town over x months is y = 72.99 + 28.45(x - 1). This equation accounts for the initial cost in the first month and the consistent monthly increase thereafter.

Answer:

0.4, 2/5

Step-by-step explanation:

The probability that Juan has to wait more than 15 minutes is 0.4 and the probability that Juan doesn't have to wait for more than 15 minutes is 0.6

Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening being equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.

Given here, there is a 40% chance that he will have to wait more than 15 minutes. Thus the probability of him waiting for more than 15 minutes is 0.4 and the probability that he has to wait less than 15 minutes is 1-0.4=0.6

Hence, P(<15)=0.6 or 3/5 and P(>15) = 0.4 or 2/5 are the  probabilites for Juan
