A line passes through the points (–5, 2) and (10, –1). Which is the equation of the line?

1 answer:

3 0

We have y - 2 = m(x + 5), where m = (-1 - 2)/(10 + 5) = -3/15 = -1/5;
Then y - 2 = (-1/5)(x + 5);
5y - 10 = (-1)(x + 5);
5y - 10 = -x - 5;
x + 5y - 5 = 0 is the equation of the line.

Answer:-288

Step-by-step explanation:

Given

First term $a_0$ is common for both AP and GP

For AP

$a_2=4=a_0+2d$ ---1

$a_4=12=a_0+4d$ ----2

From 1 & 2 we get

d=4

$a_0=-4$

$a_{10}$ for AP

$a_{10}=a_0+10d=-4+10\times 4=36$

For GP

$4=a_0r^2$ ----3

$12=a_0r^4$ ----4

From 3 & 4 we get

$3=r^2$

$r=\sqrt{3}$

$a_0=\frac{4}{3}$

For $a_{10}=\frac{4}{3}\times 3^5=324$

$AP_{a_{10}}-GP_{a_{10}}=36-324=-288$

First draw out the picture it will help. Then you can see that you want the opposite segment of the angle, which leads you to use a sine. So you have 20sin30 or 20(1/2) or 10ft.
