14. f(x) = -x4 + x² + 4; x = -1
natali 33 [55]

Answer:

  f(-1) = 4

Step-by-step explanation:

See below for the synthetic division tableau. The remainder is 4, hence ...

  f(-1) = 4

___

IMO, in this function it is far easier just to substitute -1 for x. Since the only terms are of even degree, the value of f(-1) is the sum of the coefficients:

  f(-1) = -1 +1 +4

  f(-1) = 4

1) Refer back to Lesson 2, Part A. Assume that the average shoulder width of the people in the line was 1.325 feet. How long wou
igor_vitrenko [27]

Answer:

13,250,000 feet or 13.25 million feet

Step-by-step explanation:

Each person in the line has a shoulder width of 1.325 feet.

For each person, there is a width of 1.325 ft. There are 10 million people.

Since:

10 million = 10,000,000

The total length must be:

1.325 * 10,000,000

1.325 * 10,000,000 = 13,250,000

Answer: 13,250,000 feet or 13.25 million feet

Determine the amplitude or period as requested . Amplitude of y = - 1/5 * sin x a - 1/5 1/5 b 5 d. pi/5
Brrunno [24]

Answer:

The amplitude is 1/5

Step-by-step explanation:

Given

y = -\frac{1}{5}\sin(x)

Required

Determine the amplitude

The general cosine function is:

y = A\sin(k(x + c)) +d

Where

Amplitude = |A|

Compare y = A\sin(k(x + c)) +d and y = -\frac{1}{5}\sin(x)

A = -\frac{1}{5}

So:

Amplitude = |-\frac{1}{5}|

Amplitude = \frac{1}{5}
