2. $A= \frac{r^2\pi\alpha}{360^o}$
3. $l= \frac{r\pi\alpha}{180^o}$
4. $A=ab,P=2(a+b)$
5. $C=2r\pi$
6. $A=r^2\pi$
7. $P=na,S_n=(n-2)180^o,\alpha= \frac{S_n}{n}$

How can you describe the line that passes through (0,3) and (-1, 0)

julia-pushkina [17]

let's find the equation of line passing through those two points.

slope of the given line :

$\dfrac{y_2 - y_1}{x_2 - x_1}$

$\dfrac{3 - 0}{0 - ( - 1)}$

$\dfrac{3}{ 1}$

now, let's plug the value of slope (m)

and y - intercept (c) in general equation

of line in slope intercept form.

i.e y = mx + c

so, we get the equation of given line as :

y = 3x + 3

For her phone service , Rania pays a monthly fee of $ 18 , and an additional $0.06 per minute of use. The least she has been cha

pogonyaev

Answer:

I'm assuming we need to find the number of minute she as used. to do that we can right an inequality with m being the number of minutes

18+0.06m≥88.56

we then just solve this like we would with any other algebra equation, First we subtract 18 from both sides.

0.06m≥70.56

Then we dives by 0.06

m≥1176

Rania has used at least 1176 minutes
