A quadratic equation is an algebraic expression of the second degree in x. The quadratic equation in its standard form is [tex]ax^{2} +bx+c=0[/tex] where a, b are the coefficients, x is the variable, and c is the constant term.

It is given that,

H= [tex]-16t^{2} +32t+256[/tex], which represent the height of the rock

Also, we have given that the height of the cliff is 256 feet.

Now to find the time taken by the rock, take H=0

[tex]-16t^{2} +32t+256[/tex]=0

[tex]-16(t^{2} -2t-16) = 0[/tex]

[tex]t^{2} -2t-16 = 0[/tex]

[tex]t= \frac{-(b)\pm\sqrt{(b)^{2}- 4 *a*c } )}{2*a}[/tex]

From above equation, a=1, b=-2, c=-16

So,

[tex]t= \frac{-(-2)\pm\sqrt{(-2)^{2}- 4 *1*(-16) } )}{2*1}[/tex]

[tex]t= \frac{2\pm\sqrt{(4+64 } )}{2}[/tex]

[tex]t= \frac{2\pm\sqrt{(68 } )}{2}[/tex]

There will be two value one with positive [tex]t= -2+\sqrt{(68 } )[/tex] and another with negative [tex]t= -2-\sqrt{(68 } )[/tex]

We will neglect negative value because time can't be negative.

[tex]t= \frac{2+\sqrt{(68 } )}{2}[/tex]

[tex]t= \frac{2+8.246}{2}[/tex]

[tex]t= \frac{10.246}{2}[/tex]

t= 5.123 sec

The time taken by the rock to reach the lake below is t= 5.123 sec

Isolating the absolute value term, we find

|x| + 5 ≤ 1   ⇒   |x| ≤ -4

However, the absolute value function maps every number x to a non-negative number, so |x| ≤ -4 is impossible and there is no solution to the inequality.

Answer:

  256.10

Step-by-step explanation:

You want the original price given the total amount is 307.32 and the tip rate is 20%.

Adding a tip multiplies the original price by (1 +tip rate). We can divide the total amount by this factor to find the original price:

  307.32/(1+0.20) = 256.10

The original price was 256.10.

Answer: Mean - 93.8571428571, round however you need to

Median - 75

Mode - 65

Range - 205

Step-by-step explanation: Order the numbers first. 45,65,65,75,77,80,250.

Find the mean. 45 + 65 + 65 + 75 + 77 + 80 + 250 is 657. Divide by 7 is 93.8571428571.

Median is middle. It is 75.

Mode is the most common. - 65

Range is the highest subtracted by the lowest. 250 - 45 is 205.

Answer: 2 and 4

Step-by-step explanation: They both have 3 x's

Answer:

Okay the mode means the most repeating number.

So if you write this all out:

1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4

You can now see that 3 is the most repeating number.

So 3 is the mode.

The line graph (C) represents the data representation on the line plot option (C) is correct.

A line graph is a graph made up of segments of straight lines that connect the depicted data points.

We have data shown in the table:

The data set value 11 repeated two times, so two dots we will see on the line plot.

The data set value 11(1/2) repeated one time, so one dot we will see on the line plot.

The data set value 11(3/4) repeated two times, so two dots we will see on the line plot.

The data set value 12 repeated two times, so two dots we will see on the line plot.

Similarly, we can check for others.

Thus, the line graph (C) represents the data representation on the line plot option (C) is correct.

Considering the parabolic equation, the equation for the directrix is given by x = 4.9375.

The equation of a horizontal quadratic function, of vertex (h,k), is given by:

(y - k)^2 = 4p(x - h)

The directrix is given by:

x = h - p.

In this problem, the equation is given by:

(y - 2)² = 0.25(x - 5).

Hence h = 5, p = 0.25/4 = 0.0625, hence the directrix is:

x = h - p = 5 - 0.0625 = 4.9375.

To solve this problem, we have to write out the simple harmonic motion equation and then use the respective formula to solve. The maximum kinetic energy, maximum potential energy and the maximum mechanical energy is equal to 7.56J.

The given equation of the simple harmonic motion is

[tex]x = 3.5sin(\frac{\pi}{2t} + \frac{5\pi}{4})\\[/tex]

Data;

Solving this

[tex]\frac{dx}{dt} = \theta = -3.5 * \frac{\pi}{2} cos (\frac{\pi }{2}t + \frac{5\pi}{4})\\[/tex]

Let's calculate the maximum velocity.

[tex]V_m = \frac{3.5\pi}{2}[/tex]

This is only possible when cos θ = -1

The maximum kinetic energy is

[tex]K_m = \frac{1}{2}mv_m^2 = \frac{1}{2}* \frac{500}{1000} * (\frac{7\pi}{4} )^2\\K_m = 7.56J[/tex]

The maximum kinetic energy is 7.56J

The maximum potential energy can be calculated as

[tex]\omega^2 = \frac{k}{m} \\k = \omega^2 m \\k = \frac{\pi^2}{4} * \frac{500}{1000}\\ k= 1.254 N/m[/tex]

Using the value of spring constant, we can find the maximum potential energy

[tex]P.E = \frac{1}{2}kx^2\\P.E = \frac{1}{2} * 1.234 * 3.5^2\\P.E = 7.56J[/tex]

The maximum potential energy is 7.56J

The maximum mechanical energy is equal to the sum of maximum potential energy and the maximum kinetic energy.

[tex]ME = P.E + K.E\\ME = 7.56J[/tex]

The reason ME is equal to 7.56J is because when x is at maximum, v = 0 and makes kinetic energy equal to zero.

ME = 7.56J

From the calculations above, the maximum kinetic energy, maximum potential energy and the maximum mechanical energy is equal to 7.56J.
