Answer:

$l = 3.66$

Step-by-step explanation:

Given

$r =1$

$\theta = \frac{7\pi}{6}$

Required

The arc length (l)

This is calculated as:

$l= r\theta$

So, we have:

$l = 1 * \frac{7\pi}{6}$

$l = \frac{7\pi}{6}$

So, we have:

$l = \frac{7*3.14}{6}$

$l = 3.66$

Write this equation in vertex form.<br> y = x^2 -12x +20

kotegsom [21]

Answer:

$y = (x-6) ^ 2 -16$

Step-by-step explanation:

The vertex form for a quadratic equation has the following form:

$y = (x-h) ^ 2 + k$

Where the vertice of the equation is the point (h, k)

To transform the equation $y = x ^ 2 -12x +20$ in its vertex forms we must find its vertex.

Be a quadratic equation of the form:

$ax ^ 2 + bx + c$

Where a, b and c are real numbers, then the vertex of the equation will be:

$x = - \frac{b}{2a}$

For the given equation:

$b = -12\\a = 1$

Therefore the vertice is:

$x = - \frac{-12}{2(1)}\\\\x = 6$

Now we substitute x = 6 into the equation and find the value of k.

$y = (6) ^ 2 -12 (6) +20\\\\y = -16 = k$

Therefore the vertice is: (6, -16)

And the equation is:

$y = (x-6) ^ 2 -16$

In cell e7, create a formula that calculates the salary for sarah, one of the servers at the good breeze hotel. her salary is ca

Cloud [144]

Answer:

The formula: e7 = (b7*d7)+(c7*d7*1.5)

Step-by-step explanation:

Given:

Hours worked = b7

Hourly rate = d7

Overtime hours = c7

Salary calculation = e7

Salary = Hours worked*hourly rate + (overtime*hourly rate)*1.5

Formula

e7 = (b7*d7)+(c7*d7*1.5)

The formula e7 = (b7*d7)+(c7*d7*1.5)

Hope this will helpful to you.

Thank you.

Probability helps us to know the chances of an event occurring. There are six possible outcomes.

<h3>What is Probability?</h3>

Probability helps us to know the chances of an event occurring.

$\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}$

A.) The outcomes that are possible from the first spinner is 1, 2, and 3, while the outcomes possible from the second spinner are 2, Red and blue.

All the possible outcomes from this two spinner are,

(B,1), (B,2), (B,3), (R,1), (R,2), and (R,3).

Hence, there are six possible outcomes.

B.) The letters that can be used are A and B. The numbers that can be used are 1, 2, 3, and 4.

All the possible out comes are,

(B,1), (B,2), (B,3)(B,4), (A,1), (A,2), (A,3), and (A,4).
