Which inequality is represented by the graph

Well, accordingly to the graph, it has a positive slope so we can eliminate b and d. So it is either a or c. As x increases, so does y. Y is almost not quite equal to 3x-2. In fact, it is greater, so I'd go with A. I'm pretty confident.

Answer:

C) Inequality   y ≤ 3x -2

Step-by-step explanation:

Given  : Graph

To find : Which inequality is represented by the graph.

Solution : We have given graph.

Slope intercept form of line : y = mx + b.

Where, m = slope , b = y intercept,

We can see from given graph line is solid and shaded down.

For shaded down and solid we use less than or equal to sing

So, the inequality would be y ≤.

Y intercept ( where the line cut at y axis ).

Now, slope = 3 and y intercept = -2

So , equation become  y ≤ 3x - 2.

Therefore, C) Inequality   y ≤ 3x - 2.

What is the diameter of a sphere with a volume of 332\text{ cm}^3,332 cm 3 , to the nearest tenth of a centimeter?
Korvikt [17]

Answer:

The diameter is 8.6cm

Step-by-step explanation:

Given

Shape: Sphere

Volume = 332cm^3

Required

Determine the diameter of the sphere

First, calculate the radius using:

Volume = \frac{4}{3} \pi r^3

Substitute: Volume = 332cm^3

332= \frac{4}{3} \pi r^3\\

Solve for r

r^3 = \frac{332 * 3}{4 * \pi}

r^3 = \frac{996}{4 * \pi}

r^3 = \frac{249}{\pi}

r^3 = \frac{249}{3.142}

r^3 = 79.25

Take cube roots

r = \sqrt[3]{79.25}

r = 4.3

Diameter (D) is calculated as:

D = 2r

D = 2 * 4.3

I need help on part b the showing part!!
Nastasia [14]
X^2 = 3x + 5
x^2 - 3x - 5 = 0

a(alpha) and b(beta are roots
(x - a)(x - b) = 0
x^2 - (a+b)x + ab = 0

compare coefficients
a+b = 3
ab = -5

solving
(1/a^2 + 1/b^2)
= (a^2 + b^2)/(ab)^2
= (a^2 + 2ab + b^2 - 2ab)/(ab)^2
= [(a+b)^2 - 2ab]/(ab)^2
= [(3)^2 - 2(-5)]/(-5)^2 =...

prove
a^4 = 57a + 70

let x=a,
a^2 = 3a + 5
(a^2)^2 = (3a + 5)^2
a^4 = 9a^2 + 30a + 25
a^4 = 9(3a + 5) + 30a + 25
a^4 = 57a + 70
