Mkey [24]

Answer:

a=-1 b=3 h=-4 k=5. Hope this helps.

Step-by-step explanation:

We need to find transformations from f(x) to g(x).

K is formula usually means vertical shift. Vertical shift are usually at right end of formula. f(x) has a vertical shift of zero, while g(x) vertical shift is 5. So our k is 5.

h represent our horizontal shift in a equation.

Our horizontal shift is opposite of the sign given.

F(x) has no hoeinzontal shift, while g(x) has x+4.

Set x+4=0

x + 4 = 0

x  =  - 4

so our h is -4.

B represent our horizontal compression or stretch.

Our horizontal compression/stretch is reciprocal of our b given.

f(x) has no compression or stretch, while g(x) has 1/3x.

Set 1/3x to one.

\frac{1}{3} x = 1

x = 3

so our b is 3.

A represents the vertical compression/ stretch. F(x) doesnt have one but G(x) does.

Since it has just a negative sign in front of it, the compression is -1 so a=-1

These are the cost and revenue functions for a line of trumpets sold at a music store:
Maslowich

Answer:

168 trumpets for $1702

Step-by-step explanation:

Profit is the measure to be maximized.  We are given revenue and cost relationships as a function of units, x (trumpets).  Profit is the difference:

Profit = Revenue[R(x)] - Cost[C(x)]

Profit = (76x – 0.25x^2) - (-7.75x + 5,312.5)

Profit = 76x - 0.25x^2 + 7.75x - 5,312.5

Profit = 76x - 0.25x^2 + 7.75x - 5,312.5

Profit = - 0.25x^2 + 83.75x - 5312.5

At this point we can find the trumpets needed for maximum profit by either of two approaches:  algebraic and graphing.  I'll do both.

<u>Mathematically</u>

The first derivative will give us the slope of this function for any value of x.  The maximum will have a slope of zero (the curve changes direction at that point).  Take the first derivative and set that equal to 0 and solve for x.

First derivative:

d(Profit)/dx = - 2(0.25x) + 83.75

d(Profit)/dx = - 0.50x + 83.75

0 = - 0.50x + 83.75

0.50x = 83.75

x = 167.5 trumpets

<u>Graphically</u>

Plot the profit function and look for the maximum.  The graph is attached.  The maximum is 167.5 trumpets.

Round up or down to get a whole trumpet.  I'll go up:  168 trumpets.

<u>Maximum Profit</u>

Solve the profit equation for 168 trumpets:

Profit = - 0.25x^2 + 83.75x - 5312.5

Profit = - 0.25(168)^2 + 83.75(168) - 5312.5

<u>Profit = $1702</u>

charle [14.2K]

Answer:

65/97 or 0.67

Step-by-step explanation:

TanY = opposite/adjacent

TanY = XZ/YZ

TanY = 65/97

= 0.6701030928
