The slope is (4,3). You look at the y intercept (where the y axis is crossed by the line) and simply count rise over run until you reach the next point. The next point from the y intercept (-2,0) is (2,3).

-2+4=2
0+3=3

And there you go. In fraction form it’s 4/3.

Hi i'd be glad to help you with this equation.

basically all we have to do is find (65%) of 455*.

65% of 455* = 295.75

Next.

455 + 295.75 = 750.75

So, to check my work I have 750.75 miles in total.

I have already driven 455 miles of 750.75 miles.

Using subtraction we subtract our distance from our total.

750.75 - 455 = 295.75

So, in total your answer to this problem is (295.75)

Hope this helps.
Have a great day!

Exact value of cos45

Anit [1.1K]

It's a value you should probably memorize:

$\cos45^\circ=\dfrac{\sqrt2}2=\dfrac1{\sqrt2}$

You can derive it using some trigonometric identities, other known values of cosine, and properties of the cosine function. For example, using the double angle identity for cosine:

$\cos^2x=\dfrac{1+\cos2x}2$

If $x=45^\circ$ , then

$\cos^245^\circ=\dfrac{1+\cos90^\circ}2$

and you probably know that $\cos90^\circ=0$ , so

$\cos^245^\circ=\dfrac12$

When we take the square root, we should take the positive root because $\cos x>0$ whenever $0^\circ$ :

$\cos45^\circ=+\sqrt{\dfrac12}\implies\cos45^\circ=\dfrac1{\sqrt2}$
