Answer: 111.11 seconds

Step-by-step explanation:

Given: The period of a pendulum is the time the pendulum takes to swing back and forth

The function relates the length [tex]L= 0.81t[/tex] in feet of a pendulum to the time t in seconds that it takes to swing back and forth.

If L= 90 feet then put this in the above function, we get

[tex]90=0.81t\\\\\Rightarrow\ t=\dfrac{90}{0.81}\\\\\Rightarrow\ t=111.1111111\approx111.11\text{ seconds}[/tex]

Hence,  the period = 111.11 seconds

Answer:

x = 22

Step-by-step explanation:

90 = (5x - 20)

+20         +20

110 = 5x

/5      /5

22 = x

Explanation:

To simplify a polynomial, we have to do two things: 1) combine like terms, and 2) rearrange the terms so that they're written in descending order of exponent.

First, we combine like terms, which requires us to identify the terms that can be added or subtracted from each other. Like terms always have the same variable (with the same exponent) attached to them. For example, you can add 1 "x-squared" to 2 "x-squareds" and get 3 "x-squareds", but 1 "x-squared" plus an "x" can't be combined because they're not like terms.

Let's identify some like terms below.

f(x)=−4x+3x2−7+9x−12x2−5x4

Here you can see that -4x and 9x are like terms. When we combine (add) -4x and 9x, we get 5x. So let's write 5x instead:

f(x)=5x+3x2−7−12x2−5x4

Let's do the same thing with the x-squared terms:

f(x)=5x+3x2−7−12x2−5x4

f(x)=5x−9x2−7−5x4

Now there are no like terms left. Our last step is to organize the terms so that x is written in descending power:

f(x)=−5x4−9x2+5x−7

The graph of equation y = - 2x - 1 and the y-intercept (0, - 1) is shown in image.

We have to given that,

To plot the equation y = - 2x - 1 and the y-intercept on the graph.

Since, The equation of line in slope intercept form is,

y = mx + c

Where, m is slope and c in y - intercept.

Here, Equation is,

y = - 2x - 1

After comparing,

y - intercept = - 1

So, y - intercept of equation (0, - 1)

T= 160 + 4x

Step-by-step explanation:

Giving the following information:

The $160 fine is a fixed cost. It will remain constant.

The $4 additional fine acts as a variable cost. It varies with the number of miles per hour.

To calculate the total cost (T), we need to use the following formula:

T= 160 + 4x

x= miles per hour exceeding the speed limit.

Step-by-step explanation:

The value of sin(2x) is [tex]\sin(2x) = - \frac{\sqrt{15}}{8}[/tex]

The cosine ratio is given as:

[tex]\cos(x) = -\frac 14[/tex]

Calculate sine(x) using the following identity equation

[tex]\sin^2(x) + \cos^2(x) = 1[/tex]

So we have:

[tex]\sin^2(x) + (1/4)^2 = 1[/tex]

[tex]\sin^2(x) + 1/16= 1[/tex]

Subtract 1/16 from both sides

[tex]\sin^2(x) = 15/16[/tex]

Take the square root of both sides

[tex]\sin(x) = \pm \sqrt{15/16[/tex]

Given that

tan(x) < 0

It means that:

sin(x) < 0

So, we have:

[tex]\sin(x) = -\sqrt{15/16[/tex]

Simplify

[tex]\sin(x) = \sqrt{15}/4[/tex]

sin(2x) is then calculated as:

[tex]\sin(2x) = 2\sin(x)\cos(x)[/tex]

So, we have:

[tex]\sin(2x) = -2 * \frac{\sqrt{15}}{4} * \frac 14[/tex]

This gives

[tex]\sin(2x) = - \frac{\sqrt{15}}{8}[/tex]

Answer:

The total cost of the games (play package)

= 15x - 5

Step-by-step explanation:

Number of tokens in the games = 15

The cost per token = x

Discount off the total cost = $5

Therefore, the cost of the play package = 15x - 5

where x is in dollars

However, ‘x’ can also assume any value.

Check:

If x = $15

The total cost of the game can be said to be 15(10) - 5 = $220
