Given:

A driver is below the surface of the water at - 15m. he dives down by 6m, then rises 4m.

To find:

The current location of the driver.

Solution:

In this problem, negative sign is used for downward direction or the distance below the surface of the water.

Initial location = -15 m

Dives down by 6m, it means - 6m, then rises 4m, it means 4 m.

Now, the current location is

$-15 m-6m+4m$

$=-21m+4m$

$=-17m$

Therefore, the correct location of the driver is at -17 m it means her is 17 m below the surface of the water.

Solve the equation by completing the square 5x(x+6)=-50

motikmotik

First lets distribute the 5x
5x^2 + 30x = -50

Lets divide every term by 5
x^2 + 6x = -10

To complete the square we have to half the b value, which in this case is 6. Then square it.
Half of 6 is 3, 3 squared is 9

Add that to both sides of the equation
x^2 + 6x + 9 = -1

Find the binomial squared
(x+3)^2 (If you're wondering how i got that please comment)

(x+3)^2 = -1

Take the square root of the equation of both sides
(x+3) = +/- i
x = -3 +/- i
x = -3 - i
and
x = -3 + i

How do u do this problem: W/6+5/8=-1 3/8 I got this answer: -1 53/64

Kobotan [32]

We have question
$\frac{W}{6}+ \frac{5}{8} =-1 \frac{3}{8}$
$\frac{W}{6} + \frac{5}{8} =- \frac{11}{8}$ /*8 (multiply both sides by 8)
$\frac{W8}{6} + \frac{5}{1} =- \frac{11}{1}$ /*6 (multiply both sides by 6)
$8W+5*6=-11*6$ /-30 both sides
8W=-66-30
8W=-96
W=-12
