What is the definition of f(x)? and where on the graph can you find it?

1 answer:

3 0

F(x) is just another way to express the "y" in an equation. f(x) is function notation. f(x) = 3x-4 is just another way of writing y = 3x-4. f(x) is found on a graph as the y value that comes out when the x value is applied to the function.

Name the solid and find its volume. Use 3.14 as the approximate value of pi.

sineoko [7]

It is given in the question that the solid is a cone with height of 16 units and radius of 7 units .

The formula of volume of cone is

$V = \frac{1}{3} \pi r^2 h$

To find the volume, we substitute the given values of r and h and use 3.14 for pi. That is

$V = \frac{1}{3} *3.14*7^2 *16 = 820.6 \ units \ cube$

And that's the required volume of the cone .

Two times x is 8 more than y. The sum of x and two times y is 14. Write two equations and graph to find the value of y.

Sauron [17]

Option B: $y=4$ is the value of y

Explanation:

It is given that "Two times x is 8 more than y". Writing it as expression, we have,

$2x=8+y$

It is also given that "The sum of x and two times y is 14". Writing it as expression, we have,

$x+2y=14$

To find the value of y, let us solve the two equations using substitution method.

From the equation $2x=8+y$ , let us find the value of x.

$x=\frac{8+y}{2}$

$x=\frac{8}{2} +\frac{y}{2}$

$x=4+\frac{y}{2}$

Now, substituting $x=4+\frac{y}{2}$ in the equation $x+2y=14$ , we get,

$4+\frac{y}{2}+2y=14$

$4+\frac{5y}{2} =14$

$\frac{5 y}{2}=10$

$5y=20$

$y=4$

Thus, the value of y is $y=4$

The function

Lubov Fominskaja [6]

Answer:

3 seconds.

Step-by-step explanation:

f(t) = height of the disc = -18t^2 + 42t + 36.

This equals zero when it completes its path, so:

-18t^2 + 42t + 36 = 0

-6(3t^2 - 7t - 6) = 0

-6 (3t + 2)(t - 3) = 0

t = 3 seconds (We ignore the negative zero).
