7.3; 74°

7.4; 73°

7.4; 74

Answers

Answer:

It's 7.3; 74!

Step-by-step explanation:

This was a lucky guess for me on my homework and it was correct sooooo.... I don't really have an explanation...

Definition: For vector [tex]v=<a,b>[/tex], the magnitude is defined as [tex]|v|=\sqrt{a^{2} +b^{2} }[/tex], and the direction of the vector is defined as [tex]tan^{-1}(\frac{b}{a} )[/tex].

Here, [tex]v=<2,7>[/tex].

Then, magnitude is:

[tex]|v|=\sqrt{2^{2}+7^{2} } \\|v|=\sqrt{4+49 } \\|v|=\sqrt{53} \\|v|=7.3[/tex]

The direction is:

[tex]tan^{-1}(\frac{7}{2} )=74^{o}[/tex].

So, the correct option is 7.3,74°.

Which one doesn't belong? Explain your reasoning

Answers

Answer:

A does not belong

Step-by-step explanation:

A does not belong because it is the only option with parallel lines. All other answer options have lines that intersect with eachother.

Answer:

The answer that they're looking for is A. The first set doesn't belong because it's the only one in which the lines are parallel.

However, one could argue that none of the others belong;

B is the only one with two lines instead of 3

C is the only one with three lines converging at the same point.

D is the only one with more than one point of intersection

But it is pretty clear that the answer sought is A. It's the only one with parallel lines.

Answer:

Ruby needs 7 combined.

Step-by-step explanation:

If she needs 1/4 cup of powdered milk for one batch, then we multiply 1/4 by 4 to see how much she needs for 4 batches, which is 4/4, or one whole.

If she needs 3/2 cups of whole wheat for one batch, then we multiply 3/2 by 4 to see how much she needs for 4 batches, which is 12/2, or 6.

Then we combine 6 and 1, which is 7.

Answer:

UT = 8

Step-by-step explanation:

From the picture, we can make the following equation...

5 + 2x - 6 = x + 6

By solving it we get

5 + 2x - 6 = x + 6

2x - 1 = x + 6

2x = x + 7

x = 7

Therefor if UT = 2x - 6, then UT is equal to...

2x - 6 = UT

2(7) - 6 = UT

14 - 6 = UT

8 = UT

25 points What is the equation for the line in slope-intercept form

Answers

Answer:

y=8x

Step-by-step explanation:

x=1 y= 8

x=2 y=16

8=m+b

16=2m+b

m=8

y=8x

Choose 2 coordinates from the line. Let’s pick (0,0) and (2,16)

The equation of a line is on the form y = mx + b where m is the slope and b is the y-intercept.

First let’s find the slope:

m = (y2-y1)/(x2-x1) = (16-0)/(2-0) = 16/2= 8

So we have y = 8x + b

We substitue one of the coordinates to find b. Let’s substitute (0,0)

We get 0 = 0 + b. So b = 0

The equation of the line is y = 8x

What faults in other people made Muhammad angry? Plzzzzzz help ! Correct answers only 15 points First, moles do wreak havoc in the soil. Moles eat earthworms and small invertebrate creatures in the soil. The tunnels moles create are basically worm traps. The mole senses when a worm falls into a tunnel and can quickly capture and eat its victim. To dig these tunnels, however, moles have to dig away the roots of grass and plants. This often kills the plant. If you make your living from the plants the moles destroy, you may not be happy to find them in your soil.
