Find all relative extrema of the function. use the second derivative test where applicable. (if an answer does not exist, enter
Alinara [238K]
The given quadratic describes a parabola that opens upward. Its one absolute extreme is a minimum that is found at x = -3/2. The value of the function there is
  (-3/2 +3)(-3/2) -1 = -13/4

The one relative extreme is a minimum at (-1.5, -3.25).

_____
For the parabola described by ax² +bx +c, the vertex (extreme) is found where
  x = -b/(2a)
Here, that is x=-3/(2·1) = -3/2.

An angle is equal to one-third of its complement. Find the angle's measure.
artcher [175]

Let x^\circ be the measure of the angle in question. Its complement has measure (90-x)^\circ. We're told that this angle is congruent to 1/3 of its complement, so that

x^\circ=\dfrac{(90-x)^\circ}3\implies3x^\circ=(90-x)^\circ\implies4x^\circ=90^\circ\implies x=22.5^\circ

In a mid-size company, the distribution of the number of phone calls answered each day by each of the 12 receptionists is bell-s
Radda [10]

Answer:

68%

Step-by-step explanation:

The Standard Deviation Rule = Empirical rule formula states that:

68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.

95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.

From the question,

Step 1

We have to find the number of Standard deviation from the mean. This is represented as x in the formula

μ = Mean = 61

σ = Standard Deviation = 8

For x = 53

μ - xσ

53 = 61 - 8x

8x = 61 - 53

8x = 8

x = 8/8

x = 1

For x = 69

μ + xσ

69 = 61 + 8x

8x = 69 - 61

8x = 8

x = 8/8

x = 1

This falls within 1 standard deviation of the mean where: 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.

Therefore, according to the Standard Deviation Rule, the approximate percentage of daily phone calls numbering between 53 and 69 is 68%

Log8(216)+[log(42)_log(6)]÷log(49)​
makkiz [27]

Answer:

  • 3 log (3) + 1/2

Step-by-step explanation:

  • log8(216) + [log(42) - log(6)] ÷ log(49)​ =
  • log (216)/ log (8) + [log (7) + log (6) - log (6)] ÷ 2 log (7) =
  • 3 log (3) log (2)  / 3 log (2) + log (7) / 2 log (7) =
  • 3 log (3) + 1/2
