6 0

Answer: F (cos(230)).
Explanation:
Cosine corresponds to the x coordinate of points on a circle when the radius is drawn in like this, so the answer would be the cos of that angle, but you have to account for the fact that the 50 degree angle marked is just the reference angle not the entire angle so you have to add 180 degrees to that to get 230.

Answer:

4.8

Step-by-step explanation:

$V_{sphere} = \frac{4}{3} \pi r^3$

$144\pi= \frac{4}{3} \pi r^3$

$r^3 = \frac {3 \times 144\pi}{4\pi}$

$r^3 = 3 \times 36$

$r^3 = 108$

$r = \sqrt[3]{108} \\ \\ r = 4.7622031559 \\ \\ r \approx \: 4.8 \:$

Can someone tell me the slope ?

borishaifa [10]

Answer:

slope = 4

Step-by-step explanation:

We can find the slope of a line when knowing 2 points by using the slope formula, $\frac{y_2 - y_1}{x_2 - x_1}$ . $x_1$ and $y_1$ represent the x and y values of the first point, respectively. $x_2$ and $y_2$ represent the x and y values of the second point, respectively.

The two points we have are (2,8) and (0,0). So, in this case, $x_1$ = 2, $y_1$ = 8, $x_2$ = 0, and $y_2$ = 0. Let's substitute those values into the formula and solve to get the slope:

$m =$ $\frac{0-8}{0-2}$

$\frac{-8}{-2}$

$4$

So, the slope is 4.
