Answer:

48.2

Step-by-step explanation:

√(x2-x1)²+(y2-y1)²

√(15.3-59.5)² +(14.9-34.2)²

√(-44.2)² + (-19.3)²

√1953.64+372.49

Use the inverse cosine to find the measure of angle Q.
Rom4ik [11]

Answer:

∠ Q ≈ 53.1°

Step-by-step explanation:

cos Q = \frac{adjacent}{hypotenuse} = \frac{QS}{QR} = \frac{6}{10} , then

∠ Q = cos^{-1} (\frac{6}{10} ) ≈ 53.1° ( to the nearest tenth )

Which of the following would best represent a cosine function with an amplitude of 3, a period of pi/2 , and a midline at y = –4
Grace [21]
To transform the function f(x)= cos(x) to have the amplitude of 3, we need to multiply the constant 3 to the function f(x), so we have y=3f(x)

To transform the function f(x)=cos(x) to have the midline y=-4 we need to subtract f(x) by 4, so we have y=f(x)-4, 

To transform the function f(x)=cos(x) to have period of \frac{ \pi }{2}, we need to divide the original period 2 \pi by 4, so we have y=f(4x). Note that it is the 4x gives the effect of dividing the points on x-axes by 4 and the period is read on x-axes

Hence, the full transformation is given y=3f(4x)-4 which is the last option

The table below shows the typical hours worked by employees at a company. A new employee is offered an annual salary of $37,000.
Mademuasel [1]

Answer:

Salaried pay is preferable for a new employee

Step-by-step explanation:

<u>As per table, hours worked per week:</u>

  • 0+ 8.5+ 9.5+ 7.5+ 8+ 8.5+ 4 = 46

<u>Employee gets paid for 46 hours per week:</u>

  • $40*14 + (46- 40)*$21 = $686

<u>Average yearly salary would be:</u>

  • $686/7*365 = $35770

<u>Comparing with annual salary, we see:</u>

  • $37000 > $35770

As we see, hourly employees get paid less, so the new employee should choose annual salary option
