Bumek [7]

Answer:

<h2><u><em>$71,713</em></u></h2>

Explanation:

  • Find The Total Cost Of The 355 Chairs
  • 355 Chairs - $199 Per Chair

355 · 199 = $70,645

  • Club Spent $70,645 And Had $1,068 Remaining

$70,645 + $1,068 = $71,713

Suppose that we don't have a formula for g(x) but we know that g(3) = −1 and g'(x) = x2 + 7 for all x.
Sliva [168]

Answer:

  • g(2.95) ≈ -1.8; g(3.05) ≈ -0.2
  • A) tangents are increasing in slope, so the tangent is below the curve, and estimates are too small.

Step-by-step explanation:

(a) The linear approximation of g(x) at x=b will be ...

  g(x) ≈ g'(b)(x -b) +g(b)

Using the given relations, this is ...

  g'(3) = 3² +7 = 16

  g(x) ≈ 16(x -3) -1

Then the points of interest are ...

  g(2.95) ≈ 16(2.95 -3) -1 = -1.8

  g(3.05) ≈ 16(3.05 -3) -1 = -0.2

__

(b) At x=3, the slope of the curve is increasing, so the tangent lies below the curve. The estimates are too small. (Matches description A.)

Use the number line to answer the question. Each tick represents 1 unit.
Yanka [14]

Answer and Step-by-step explanation:

Essentially, you are describing the position of point K using the location of the other points on the graph.

<u>Let's start listing some descriptions:</u>

K is:

<em>3 more than H</em>

<em>2 more than J</em>

<em>3 less than L</em>

<em>4 less than M</em>

<em>7 less than N</em>

<em>12 less than P</em>

<em />

<u>Now look at the answer choices and compare it to what we wrote.</u>

We see that the answer choices A, B, and D are incorrect (based on what we wrote), and that answer choice C is correct.

<u>[C. 7 less than N] is the correct answer.</u>
