150 degrees because supplementary angles add up to 180 degrees

What is the distance between the points (-4, 6) and (1, -6)?

Oksanka [162]

Answer:

The distance between these 2 points is 13.

Step-by-step explanation:

Picture the 2 points on a graph as a right triangle, where the hypotenuse of that right triangle is the distance between the points. It is very easy to find the length of the legs of that triangle, and you can use those legs to calculate the length of the hypotenuse.

First, find the vertical distance, or the distance between the y-coordinates. Either just look at a graph and count, or subtract them.

$-6-6=-12$

Distance is an absolute value from 0, so -12 is the same as 12.

Next, find the horizontal distance between the x-coordinates.

$1--4=5$

Now, we have the length of the legs, 5 and 12. Use the pythagorean theorem to find the length of the hypotenuse:

$a^2+b^2=c^2\\5^2+12^2=c^2\\25+144=c^2\\c^2=169\\c=\sqrt{169}\\c=13$

The distance between these 2 points is 13.

Which of the following angles is coterminal with one that measures 98 degrees

polet [3.4K]

Answer:

See below

Step-by-step explanation:

You have not provided the options.

But I will explain how you can work it.

Coterminal angles are two or more angles that have the same terminal side in standard.

If you want to find an angle that is coterminal with 98°, you keep adding or subtracting 360°.

$98 + 360 = 458 \\ 98 + 2 \times 360 = 818$

$98 - 360 = - 262$

Therefore 488°, 818°, -262° are examples of angles that are coterminal with 98°

At what point do the curves r1(t) = t, 5 − t, 48 t2 and r2(s) = 8 − s, s − 3, s2 intersect?

DerKrebs [107]

Set components equal:
$t = 8-s \\ 5-t = s-3 \\ 48 t^2 = s^2$

From this we find:
$t = 8-s \\ s = 4 \sqrt{3} t$

Substitute and solve system:
$t = \frac{8}{1+4 \sqrt{3}} = 1.009 \\ \\ s = 8-t = 8 - 1.009 = 6.991$

The point where they intersect is:
$(1.009, 5-1.009, 48(1.009)^2)$
