Answer:

x = 0

Or

x = -25

Step-by-step explanation:

x^2 + 25x = 0

Factorise

x( x + 25)=0

x = 0

Or

x + 25 = 0

The formula for determining the pressure, p, exerted on an object at a depth, h, below the surface of a liquid is p = s + dgh, where s is the atmospheric pressure, d is the density of the liquid, and gas the acceleration due to gravity.

p = s + dgh

dgh = p - s

h = (p - s)/dg

Which formula represents h in terms of p, s, d, and g? Formula B is correct.

Which is the vertex of x2 + 10x = -17 <br><br> (-5,-8)<br><br> (5,8)<br><br> (-5,8)<br><br> (5,-8)
ad-work [718]

Answer:

vertex = (- 5, - 8)

Step-by-step explanation:

Given a quadratic in standard form : ax² + bx + c = 0 : a ≠ 0

Then the x- coordinate of the vertex is

x_{vertex} = - \frac{b}{2a}

Given x² + 10x = - 17 ( add 17 to both sides )

x² + 10x + 17 = 0 ← in standard form

with a = 1, b = 10, c = 17, then

x_{vertex} = - \frac{10}{2} = - 5

Substitute x = - 5 into the quadratic for the corresponding value of y

y = (- 5)² + 10(- 5) + 17 = 25 - 50 + 17 = - 8

Hence vertex = (- 5, - 8)
