Answer:

This question is pretty simple, half the values given are just to confuse you

notice that we are given a function which gives us the height of the rock at any given time, so if we use that function for t=2 seconds, we will get the height of the rock after 2 seconds

We are given the function:

h(t) = -16t² - 50t + 220

replacing t with 2

h(2) = -16(2)² - 50(2) + 220

h(2) = -16(4) - 100 + 220

h(2) = -64 - 100 + 220

h(2) = 56 feet

Therefore, the height of the rock 2 seconds after throwing is 56 m

What do I do about the variables

Shkiper50 [21]

3x(9x² + 11x - 5) + 2(2x³ + 11x - 5x²) - 5x² + 8

Simplify.

27x³ + 33x² - 15x + 4x³ + 22x - 10x² - 5x² + 8

Add like terms.

(27x³ + 4x³) + (33x² - 10x²) + (-15x + 22x) + 8

Simplify.

31x³ + 23x² - 7x + 8

~Hope I helped!~

Use the interactive to make a vertical line with the equation of x = 3. The line x = 3 has slope.

Sliva [168]

Answer:

Slope of equation x = 3 is not defined.

Step-by-step explanation:

The graph for equation $x = 3$ is attached.

As clear from the graph, x=3, is a straight line parallel to y-axis.

Slope:

Since the given equation of line is parallel to the y-axis and parallel lines have same slope.
Parallel lines have the same slope and will never intersect. Parallel lines continue, literally, forever without touching

Thus, the given equation will have the same slope as the y-axis.

The slope of y-axis is not defined.

Hence, the slope of this line is not defined.

Which phrase represents the graph below?

marissa [1.9K]

I would say neither of the above.

A is incorrect because in the graph, the curves get shorter over time, and if you were riding the same Ferris wheel, the curves would be the same size the whole time, because the Ferris Wheel would stay the same shape and height.

B is incorrect because the height increases then decreases and increases and decreases, etc, while the description is simply, a descending paper plane.

C is incorrect because it wouldn't be both of the above since they were both wrong.
