Answer:

292.5 km

Step-by-step explanation:

You have to first do 65 x 4 = 260

Then 65/2 = 32.5

260 + 32.5 = 292.5

Answer = 292.5 km

Answer:

292.5 km

Step-by-step explanation:

65 x 4 = 260

65/2 = 32.5

260 + 32.5 = 292.5

Ans = 292.5 km

Answer:

[tex]\displaystyle -\sqrt{3} - 2[/tex]

Explanation:

If you recall the unit circle [from the polar graph], you would have no trouble at all figuring this out, but sinse you have trouble, do not worry about it. So, here is what you should have realised:

[tex]\displaystyle \boxed{1\frac{1}{2}\pi} = \frac{18}{12}\pi[/tex]

If you did not notise, [tex]\displaystyle 1\frac{7}{12}\pi,[/tex]or [tex]\displaystyle \frac{19}{12}\pi,[/tex]is just [tex]\displaystyle \frac{\pi}{12}[/tex]more than [tex]\displaystyle 1\frac{1}{2}\pi,[/tex]which means the exact value will either be a radical, followed by an integer or just a radical. In this case, accourding to the unit circle, you will have a radical, followed by an integer, and that will be this:

[tex]\displaystyle \frac{sin\:1\frac{7}{12}\pi}{cos\: 1\frac{7}{12}\pi} = tan\:1\frac{7}{12}\pi \\ \\ \boxed{-\sqrt{3} - 2} = \frac{sin\:1\frac{7}{12}\pi}{cos\: 1\frac{7}{12}\pi}[/tex]

It is all about memorisation of the unit circle, which I know is difficult, but you will get used to it soon.

*Now, if you had to find [tex]\displaystyle cos\:\frac{7}{12}\pi,[/tex]then the exact value would be the OPPOCITE of the exact value of [tex]\displaystyle sin\:\frac{7}{12}\pi,[/tex]which is [tex]\displaystyle -\frac{\sqrt{2} + \sqrt{6}}{4},[/tex]because you would be crossing into the second quadrant where the x-coordinates are negative, accourding to both the cartesian and polar graphs. In addition, sinse you ALREADY have both values for sine and cosine [accourding to your PREVIOUS QUESTION ASKED], all you need to do is divide both values in the order given above to arrive at the exact value for [tex]\displaystyle tan\:1\frac{7}{12}\pi.[/tex]

Step-by-step explanation:

Range = Highest Value - Lowest Value

Range = 3686 - 31 = 3650 million

Mean = (803 + 487 + 348 + 3686 + 730 + 31) / 6 = 1,014.17

Median = 608.5

Answer:

Given equation:

[tex]\sqrt{30-2x} =x-3[/tex]

Square both sides:

[tex]\implies (\sqrt{30-2x})^2 =(x-3)^2[/tex]

[tex]\implies 30-2x =(x-3)^2[/tex]

Expand the right side:

[tex]\implies 30-2x =x^2-6x+9[/tex]

Add [tex]2x[/tex] to both sides:

[tex]\implies 30 =x^2-4x+9[/tex]

Subtract 30 from both sides:

[tex]\implies x^2-4x-21=0[/tex]

Factor:

[tex]\implies (x-7)(x+3)=0[/tex]

Therefore,

[tex]x-7=0 \implies x =7[/tex]

[tex]x+3=0 \implies x=-3[/tex]

Substitute both values of [tex]x[/tex] into the original equation to check:

[tex]x=7 :[/tex]

[tex]\implies\sqrt{30-2(7)} =7-3[/tex]

[tex]\implies 4=4[/tex]

correct!

[tex]x=-3[/tex]

[tex]\implies\sqrt{30-2(-3)} =-3-3[/tex]

[tex]\implies 6 \neq =-6[/tex]

incorrect!

Therefore, [tex]x=7[/tex] is the only correct solution, and [tex]x=-3[/tex] is the extraneous solution

**Extraneous solution: a root of a transformed equation that is not a root of the original equation**

Step-by-step explanation:

Answer:

1

Explanation:

1 is the mode due to the fact that it is repeated the most times out of all of the numbers in the expression that you gave (1 appears four times, whereas 2 only appears once, 3 only appears twice, 4 appears three times, and 5 also appears three times).

Subtract the difference:

Answer:

You can draw any line basically as long as it hits the point (0,3) once and only once.

So linear line.

Draw a straight line from point (0,3) on a coordinate plane from any two points, as long as it hits (0,3)

For example yuou can graph (0,3) {must} and then you can graph like 1,2 or something and then you got a line that passes throguh (0,3) unless specified slope or otherwise

Answer:

f(x)=2x-11

f(6)=2(6)-11

    =12-11

    =1

and the answer is c.

Explanation:

f(6) means you have to replace all x's in the function with 6.

For example, if the problem was asking you what is the value of f(10) you would have to replace all the x's in the respective function with 10 and so on.

Considering that it is a three-dimensional form, it's spatial measurements are height, width and length.

A two-dimensional form has two dimensions, width and length. When there are three dimensions, the height is added.

In this case, height and width are already listed, hence the length is missing.

Step-by-step explanation:

a) True since this is when the graph intersects the x axis.

b) False, this is a minimum, not a maximum.

c) True, this is tue turning point.

d) False, the axis of symmetry is x=-3, not y=-4.

Answer:

Answers 1 and 3

Step-by-step explanation:

Substitute 10 for x and 5 for y in both equations and solve.

First equation:

2x - 5y = -5

2(10) - 5(5) = -5

20 - 25 = -5

-5 = -5

True statement

Second equation:

x + 2y = 10

10 + 2(5) = 10

10 + 10 = 10

20 = 10

Not a true statement

Answer:

B

Step-by-step explanation:

Plug in coordinates to see if they match the answer.

It's easier in slope-intercept form, so lets change it first.

-2x+y=7

+2x    +2x

y=2x+7

Now we can plug in the coordinates to see if they match.

Lets try A.

11=2(-2)+7

11=-4+7

11=3

A is incorrect.

Lets try B.

11=2(2)+7

11=4+7

11=11

B is a solution, therefore is on the graph.
