Answer:

x= -2 y= -5

Step-by-step explanation:

Answer:

d-bar= ∑d/n= -0.7/ 5= -0.14

Step-by-step explanation:

Eight am             12 am             difference (8:00am- 12:00 am)= d

98.4                      98.9              (98.4-98.9=) -0.5

98.6                       99               (98.6-99=) -0.4

97.8                       97.9            (97.8-97.9=) - 0.1

97.1                       96.6             (97.1-96.6=)+0.5

97.5                       97.7              (97.5-97.7=)-0.2        

∑                                                  -0.7        

d= difference between 8 am and 12 am

First we subtract the 12.00 am times from 8:00 am times.

Then we add all the differences to get the total difference ∑d.

∑d= -0.7= total of the difference between two times.

n= number of observations=5

Putting the values in the formula would give the answer.

d-bar= d`= ∑d/n= -0.7/ 5= -0.14

Answer:

Step-by-step explanation:

p:q = ⅔:3 = 2:9 = 6:27

p:r = ¾:½ = 3:2 = 6:4

p:q:r = 6:27:4

Answer:

The component form of the velocity of the airplane is [tex]\vec v = 389.711\,\hat{i} -225\,\hat{j}\,\left[\frac{m}{s} \right][/tex].

Step-by-step explanation:

Let suppose that a bearing of 0 degrees corresponds with the [tex]+x[/tex] direction and that angle is measured counterclockwise. Besides, we must know both the magnitude of velocity ([tex]\|\vec v\|[/tex]), in miles per hour, and the direction of the airplane ([tex]\theta[/tex]), in sexagesimal degrees to construct the respective vector. The component form of the velocity of the airplane is equivalent to a vector in rectangular form with physical units, that is:

[tex]\vec v = \|\vec v\|\cdot (\cos \theta \,\hat{i}+\sin \theta\,\hat{j})[/tex] (1)

If we know that [tex]\|\vec v\| = 450\,\frac{mi}{h}[/tex] and [tex]\theta = 330^{\circ}[/tex], then the component form of the velocity of the airplane is:

[tex]\vec v = 389.711\,\hat{i} -225\,\hat{j}\,\left[\frac{m}{s} \right][/tex]

The component form of the velocity of the airplane is [tex]\vec v = 389.711\,\hat{i} -225\,\hat{j}\,\left[\frac{m}{s} \right][/tex].

Answer:

B- Max has 10$. He earns 25.75$ for every lawn that he mows.

D is also an answer.

Step-by-step explanation:

This equation is an example of the formula y=mx+b, where mx is the slope and b is the y intercept, the slope is a continuous thing where as the y- intercept is like a beginning point.

So, A is incorrect because it puts 25.75 as the y intercept when it should be the slope. C is wrong because that is not even the kind of equation we are working with, and E is a different equation. I think the only possible answers are B and D

Answer:

The answer is No you cannot turn it into a circle

Answer:

x=15

Step-by-step explanation:

This is an Isosceles Triangle, so that means there are two angels that are the same. So we could rearrange the equations to get:

[tex]3x=5x-30\\\text{ subtract 5x on both sides }\\\\-2x=-30\\\text{ divide by two on both sides }\\x=15\\[/tex]

Hope it helps.

Answer:

-512

Step-by-step explanation:

The appropriate general formula for a geometric series is a(n) = a(1)*r^(n - 1).

In this problem the first term, a(1) = 1, and the common ratio is r = -2.  The pertinent geometric series is thus:

a(n) = (-2)^(n - 1), and the 10th term is a(10) + (-2)^(10 - 1) = -512 = a(10)

Answer:

18π + 90

Step-by-step explanation:

The perimeter is the sum of quarter of the circumference and 2r , that is

P = 2πr + (45 + 45)

  = 2 × π × 36 × [tex]\frac{1}{4}[/tex] + 90

  = 2 × π × 9 + 90

  = 18π + 90

Answer: 188.5

Answer:

100 miles

Step-by-step explanation:

Remark

All you need do is start at 4 hours on the y axis and go right until you hit a dot. When you do, go down until you hit a number on the x axis.

It helps if you mark up the graph.

Go right from 4

You hit a dot

Look down.

You should see 100. That's how far you go in 4 hours.

Note

This is an odd graph. Usually time is on the x axis.
