Answer:

The desired divisor is n = 21

Step-by-step explanation:

Let that number be n.  Then:

-15/56        -5

---------- = ---------

     n            6

Through cross-multiplication we get:

(-15/56)*6 = -5n, which reduces to:

(-15)(7) = -5n, or 3(7) = n

The desired divisor is n = 21

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.)

Given the parent function f(x)=x^2 describe the graph of y=(0.2x)^2
Yanka [14]
We have the following function:
 f (x) = x ^ 2
 We have the following transformation:
 Expansions and horizontal compressions
 The graph of y = f (bx):
 If 0 <b <1, the graph of y = f (x) expands horizontally by the factor of 1 / b. 
 Applying the transformation:
 y = (0.2x) ^ 2
 The factor is:
 1 / b = 1 / 0.2 = 5
 Answer:
 
b. expanded horizontally by a factor of 5

Hana makes and sells knit scarves. She will charge $12 for each scarf she sells at the craft fair next week. She will pay a $25
Aleksandr-060686 [28]

Answer:

$12s - $25

Step-by-step explanation:

Given that:

Amount charged per scarve = $12

Cost of booth used = $25

Profit made for selling 's' scarve after paying for booth

Profit = Revenue - Expenditure

Revenue = cost per scarve * number of scarves sold

Revenue = $12 * s

Revenue = 12s

Expenditure = cost of booth

Expenditure = $25

Hence,

Profit made = $12s - $25
