The formula for the volume of a cone is V=1/3bhSolve V=1/3bh
for b, the base of the cone.

Answers

Answer 1
Answer:

Answer:

b = 3Vh

Step-by-step explanation:

When they ask to solve for b, you are essentially rearranging the equation so that b is alone on one side.

V = 1/3bh

(V)(3) = (1/3bh)(3)

3V = bh

(3V)/h = (bh)/h

3Vh = b

b = 3Vh

What mathematical operation applies (addition, subtraction, multiplication or division) and write your equation in the box below.

Answers

Equation. This word may fit your definition of a set of values or numbers –intergers- coupled with basic operations. Equation is mathematical form of body where there are two adjacent corners which aims as the word says, equation. Take for instance in illustration 2x + 5x = 7x. 

Which of the following is a polynomial function in standard form with zeros at –8, –1, and 3?A) f(x) = (x + 8)(x + 1)(x – 3)
B) f(x) = x^3 – 6x^2 – 19x + 24
C) f(x) = x^3 + 6x^2 – 19x – 24
D) f(x) = (x – 8)(x – 1)(x + 3)

Answers

Answer:

Option: C is the correct answer.

The polynomial in standard form is:

   C)    f(x)=x^3+6x^2-19x-24

Step-by-step explanation:

The standard form of a equation of a polynomial is written as :

  We arrange the terms from least to highest power of x.

We know that if a polynomial has roots as:

a, b and c then the equation of the polynomial is given by:

f(x)=(x-a)(x-b)(x-c)

Here we  have: a= -8 , b= -1 and c=3

Hence, the equation of the circle is given  by:

f(x)=(x-(-8))(x-(-1))(x-3)\n\n\nf(x)=(x+8)(x+1)(x-3)

which on expanding gives:

(x+8)(x+1)(x-3)=(x^2+9x+8)(x-3)\n\n(x+8)(x+1)(x-3)=x^3-3x^2+9x^2-27x+8x-24\n\n(x+8)(x+1)(x-3)=x^3+6x^2-19x-24

Hence, the standard equation of the polynomial is:

         f(x)=x^3+6x^2-19x-24
The answer is A because zeros of polynomial functions are found by setting each factor equal to zero and solving for x. The zeros of a function will be the opposite sign of the numbers inside each factor.

Answer:

X

Step-by-step explanation:

To be a function, the line has to pass the vertical line test. This means that when a vertical line is passed through every x value, it will only cross the graphed line once.

To help: draw vertical lines through each graph.

In graph W: the line would pass through the top and bottom of the circle - not a function

In graph X: the line passes once through every area - a function

In graph Y: the line passes through the top curve as well as the bottom curve - not a function

In graph Z: the line passes through the curves multiple times - not a function

The following lines are parallel. 2x + 6y = 5 and y = 3x + 8
a. True
b. False

Answers

To find out whether these lines are parallel or not, we have to calculate the slope. If the slope is same in both equations, then we can say both lines are parallel to each other.
For that purpose, we have to change the format of the equation in this way, y=mx+C.

2x + 6y = 5
y = -1/3 x + 5

y = 3x + 8

Since the slope ( -1/3 and 3 ) of the equations are not equal, these are not parallel to each other.

Answer is b.False

For the function y=f(x), what is the ordered pair for the point on the graph when x= b-2?A) (b-2, f(b-2))
B) (x, f(b))
C) (x, b-2)
D) (b - 2, f(b))

Answers

y=f(x)\n\nx=b-2\Rightarrow y=f(b-2)\n\nAnswer:A)(b-2;\ f(b-2))
