You're flying from Joint Base Lewis-McChord (JBLM) to an undisclosed location 40 km south and 113 km east. Mt. Rainier is located approximately 56 km east and 40 km south of JBLM. If you are flying at a constant speed of 800 km/hr, how long after you depart JBLM will you be the closest to Mt. Rainier?

Answers

Answer 1

5.12 minutes ≈ 5 minutes 7.2 seconds

What is Distance?

Distance. The length along a line or line segment between two points on the line or line segment.

Here, The flight path of the airplane is along the line ...

y = -125/135x = -25/27x

The perpendicular line through Mt. Rainier's location is ...

 y = 27/25(x -56) -40

In standard form, these two equations are ...

25x +27y = 0

27x -25y = 2512

The point of closest approach has the coordinates that are the solution to these two equations:

(x, y) = (33912/677, 31400/677)

The distance d from the origin to this point is given by the Pythagorean theorem (distance formula) as ...

d = 1256√(2/677) . . . . . km

This distance can be converted to time using the speed of the airplane:

1256√(2/677) X 60/800 =  94.2√(2/677) ≈ 5.120019 mins

Thus, 5.12 minutes after departing JBLM you will be closest to Mt. Rainier.

Justification:

Answers

As the travelling distance to work increases, number of such people decreases. Therefore this distribution shape will be skewed right.

How to depict the shape?

On each weekday, the number of sleeping hours generally remains the same. So the shape of the distribution will be uniform.

In general, most people will have their first heart attack at a higher age. So the shape of the distribution will be skewed left.

Scores of GRE will have a normal distribution in general. So the shape of the distribution will be symmetric.

Answers

the transformations used are:

Dilation of scale factor 5.Shift of 2 units to the right.Shift of 3 units up.

Which transformations are used?

We start with the function:

[tex]f(x) = 2^x[/tex]

And we have the transformed function:

[tex]g(x) = 5*2^{x-2} + 3[/tex]

Bow, let's start with the original function f(x). If first we apply a vertical dilation of scale factor 5, then we have:

g(x) = 5*f(x).

Then we apply a shift of 2 units to the right, so we have:

g(x) = 5*f(x - 2)

Then we apply a shift of 3 units up, so we have:

g(x) = 5*f(x - 2) + 3

Replacing f(x) by the actual function:

[tex]g(x) = 5*2^{x-2} + 3[/tex]

Then the transformations used are:

Dilation of scale factor 5.Shift of 2 units to the right.Shift of 3 units up.

If we know that the function crosses the x-axis at some point, then for some polynomial functions, we have those as roots of the polynomial.

Let's assume the graph of Cheryl's commute was like the one below.

We can see that she started at 0 mph.  

One minute later, she was up to 65 mph, so she had accelerated (increased her speed).

At 6.5 min (5.5 min later) her speed was still 65 mph therefore, she was driving at a constant speed.

Over the next 2.5 min, her speed dropped to 45 mph, therefore she was decelerating.

A trader bought 30 baskets of pawpaw and 100 baskets of mangoes for 2450. she sold the pawpaw at a profit of 40% and the mangoes at a profit of 30%. if her profit on the entire transaction was 855, find the cost price of a basket of pawpaw and the selling price of 100 baskets of mangoes.

Answers

The cost price of pawpaw is 40 and the cost if the basket of mangoes is 1250.

How to calculate the price?

Based on the information given, the equations to solve the question will be:

30p + 100m = 2450 .... i

1.3 × 40p - 30 p + 1.3 × 100m = 855 ..... ii

30p + 100m = 2450

12p + 30m = 855

Solving simultaneously, the price of pawpaw is 40 and the price of mango is 12.5.

Therefore, the cost of 100 basket of mangoes will be:

= 12.5 × 100

= 1250

What is the point slope form of an equation of the line through the points (-2, 6) and (3, -2)

Answers

-2-6 = -8/5 (3- -2)

first off, it’s important to know that the formula for point slope form is y-y1=m(x-x1). since you already have both points, you can plug them into the equation to get -2-6=m(3- -2). Next, you must find the slope by using the formula y2-y1/x2-x1. Plug the points in to get -2-6/3–2. Simplify to -8/5, and that’s your slope. Put the slope into the equation to get your final answer of -2-6 = -8/5 (3- -2). Hope this helped!!

Step-by-step explanation:

base 1 is 5m and we know the other base is parallel to the base of the rectangle so base 2 is 9m.

Since the total height is 7 m and the height of the rectangle is 5 m, subtract to get the height of the trapezoid: 7m - 5m = 2m

put the three values into the equation and solve:

(5m + 9m) ÷ 2 x 2m

(14m) ÷ 2 x 2m

7m x 2m
