Is x=3 a zero of f(x)=4x^4-x^3-52x^2-35x+12

Answers

Answer 1

Answer:

no

Step-by-step explanation:

If x = 3 is a zero, then f(3) = 0

f(3)

= 4[tex](3)^{4}[/tex] - 3³ - 52(3)² - 35(3) + 12

= 324 - 27 - 468 - 105 + 12

= - 264

Since f(3) ≠ 0 then x = 3 is not a zero of f(x)

Step-by-step explanation:

Answer:

Both inequalities use the division property to isolate the variable, y. When you divide by a negative number, like –7, you must reverse the direction of the inequality sign. When you divide by a positive number, like 7, the inequality sign stays the same. The solution to the first inequality is y > -23, and the solution to the second inequality is y <>

Answer:

The function form of the given equation

                        y   = 2 x + 3

Step-by-step explanation:

Explanation:-

Given   4x - 2y = -6

            4 x + 6 = 2 y

            [tex]y = \frac{4x}{2} + \frac{6}{2}[/tex]

          y   = 2 x + 3

The function form y = f(x)

The function form of the given equation

                        y   = 2 x + 3

If the volume of a cylinder is 900 cm squared with a height of 20 cm, what
is the diameter of the cylinder? Round to the hundredths.

Answers

Answer:

The diameter is 7.6 cm

Step-by-step explanation:

Mathematically, the volume of a cylinder can be calculated using the formula;

V = pi * r^2 * h

From the question;

V = 900

r = ?

h = 20

Substituting these values

900 = 3.142 * r^2 * 20

r^2 = (900)/(3.142 * 20)

r^2 = 14.32

r = √14.32

r = 3.78 cm

Mathematically, the diameter is 2 times the radius

We have this as;

2 * 3.78 = 7.6 cm
