Write the following in slope intercept form:
BabaBlast [244]
To change it into slope intercept (y=mx+b) you just replace the inequality with an equality and isolate y

x<=2:
x=2=y-> y=2 or y=2+0x

2x-3y>=4:
2x-3y=4
2x-4=3y
(2/3)x-(4/3))=y
y=(2/3)x-(4/3)

x+y>0:
x+y=0
y=-x or y=-x+0

Help me solve the volume for the sphere?
iogann1982 [59]

Answer:

38.77 yd³

Step-by-step explanation:

The volume of the sphere can be determined by using the formula 4πr³/3.

[Where "r" is the radius of the circle].

<u>We are given that:</u>

Radius of circle = 2.1 yd

<u />

<u>When we substitute the radius in the formula, we get;</u>

⇒ 4 × π × (2.1)³/3

<u>Let π be substituted as 3.14. Then;</u>

⇒ 4 × π × (2.1)³/3

⇒ 4 × (3.14) × (2.1)³/3

<u>When evaulating the cube of 2.1, we get;</u>

⇒ 4 × (3.14) × (2.1)³/3

⇒ 4 × (3.14) × (2.1) × (2.1) × (2.1)/3

<u>When simplified, we get;</u>

⇒ 4 × (3.14) × (2.1) × (2.1) × (2.1)/3

⇒ 4 × (3.14) × (2.1) × (2.1) × (0.7)

⇒ 4 × (3.14) × (4.41) × (0.7)

⇒ (12.56) × (4.41) × (0.7)

⇒ 38.77272 ≈ 38.77 yd³          (Rounded to nearest hundredth)    

Therefore, the volume of the sphere is 38.77 yd³.

Find the solution set by factoring and using the zero product rule or by using the quadratic formula
-Dominant- [34]
Answer:
The solution set is:
{x = \frac{1}{6} + \frac{ \sqrt{13} }{6} \: or \: x = \frac{1}{6} - \frac{ \sqrt{13} }{6}}

Step-by-step explanation:

Comparing the general equation,

a{x}^{2} + bx + c = 0

to

3{x}^{2} - x - 1 = 0

It can be testified that,

a = 3

b = - 1

and

c= - 1

The quadratic formula is given by:

x = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac } }{2a}

We now substitute the values of a, b and c into the formula

x = \frac{ - ( -1) \pm \sqrt{ { (- 1)}^{2} - 4(3)( - 1) } }{2(3)}

\implies x = \frac{1\pm \sqrt{ { 1} +12 } }{6}

\implies x = \frac{1\pm \sqrt{ {13 } } }{6}

\implies x = \frac{1}{6} + \frac{ \sqrt{13} }{6} \: or \: x = \frac{1}{6} - \frac{ \sqrt{13} }{6}
