If a is (-8, 3) and c is (12, -4), find b if it is 2/5 the distance from a to c

ohaa [14]

Answer:

(0, 1/5)

Step-by-step explanation:

Since b is 2/5 of the distance from a to c, it is ...

b = a + 2/5(c -a) = 3/5a +2/5c

b = (3a +2c)/5 = (3(-8, 3) +2(12, -4))/5 = (-24+24, 9-8)/5 = (0, 1/5)

Point b is (0, 1/5).

Verify the identity. (cos x/ 1+ sin x) + (1+ sin x/cos x) = 2 sec x

Gekata [30.6K]

Answer:

LHS

$\frac{cos x}{1+ sin x} + \frac{1+ sin x}{cos x} \\=\frac{cos2(x)+1+2sin(x)+sin2(x)}{cos(x)(1+sin(x)} \\= \frac{2+2sin(x)}{cos(x)(1+sin(x))} \\\\=\frac{2 (1 + sin(x))}{cos(x)(1+sin(x))} \\= \frac{2}{cos (x)} \\= 2 sec x$

= RHS PROVED

hope it helps :)
