Point A is 3 units above the y axis and point B is 3 units below the y axis, so they are both 3 units away from the y axis.

In the function f(x)=5(x^2-4+___)+15, what number belongs in the blank to complete the square?

Maurinko [17]

Answer:

2² = 4

Step-by-step explanation:

$\text{Use}\\(a-b)^2=a^2-2ab+b^2\\\\f(x)=5(x^2-4x+\underline{\ \ \ })+15\\\\x^2-4x\\\\x^2-2(x)(2)\\\\x^2-2(x)(2)+2^2=x^2-4x+4\\\\\text{Therefore}\\\\f(x)=5(x^2-4x+4)+15=5(x-2)^2+15$

How do you solve this equation, 5s^2-14s-3=0

elena55 [62]

It's a quadratic equation. Solve it through factorisation.

5s^2 - 14s - 3 = 0
(5s + 1)(s - 3) = 0

5s + 1 = 0
or
s - 3 = 0

Therefore

s = -1/5
or
s = 3

A cylinder has an 18-inch diameter and is 15 inches tall. It is filled to the top with water. A 6-inch-diameter ball is

Goshia [24]

water in cylinder = 1.179π in³

<h3>Further explanation</h3>

Volume is a derivative quantity derived from the length

The unit of volume can be expressed in liters or milliliters or cubic meters

The volume of the cylinder

V = πr².h

the volume of ball

V= 4/3πr³

volume of cylinder

$\tt V=\pi.9^2.15=1215\pi$

volume of the ball

$\tt V=\dfrac{4}{3}\pi.r^3\\\\V=\dfrac{4}{3}.\pi.3^3=36\pi$

water in the cylinder

V cylinder - V ball

$\tt 1215\pi-36\pi=1179\pi$
