3x^2+5x-2=0 solve quadratic equation by factoring

1 answer:

5 0

Hmm

trial and error
factor
(3x-2)(x+1) nope
(3x+2)(x-1) nope
(3x-1)(x+2) yes

(3x-1)(x+2)=0

set them to zero
3x-1=0
3x=1
x=1/3

x+2=0
x=-2

x=-2 and 1/3

adoni [48]

Answer:

$x=0.3090984+\frac{2\pi n}{3},0.73809914+\frac{2\pi n}{3}$

Step-by-step explanation:

$5sin(3x)-1=3$

$5sin(3x)=4$

$sin(3x)=\frac{4}{5}$

$3x=0.92729521+2\pi n,2.21429743+2\pi n$

$x=0.3090984+\frac{2\pi n}{3},0.73809914+\frac{2\pi n}{3}$

A driver was at 60m below sea level. the driver swam up 2m every 5 seconds.explain whether the driver would have reached the sea

Luda [366]

Answer: No

Step-by-step explanation:

The diver is at 60m below sea level, and swims upward 2m every 5 seconds.

So, since there are 24 five-second periods in 2 minutes (60secs/min), the diver would have swam up 48m after 2 minutes.

Since 60m - 48m is 12m, the diver has not yet reached the sea surface.

Hope it helps :)
