Answer:

a) Since the income is more than the cost, she makes a profit.

b) To make profits, she must sell at least 17 necklaces

Step-by-step explanation:

Inequalities

The costs of selling jewelry at a fair are $135 to rent a booth and $4 for each necklace. The cost function is:

C(n) = 135 + 4n

Where n is the number of necklaces she sells at the fair. She sells each necklace at $12 each, thus the income function is:

R(n) = 12n

a) If she sells n=17 necklaces, it will cost:

C(17) = 135 + 4*17 = 203

And the income is:

R(17) = 12*17= 204

Since the income is more than the cost, she makes a profit.

b) To make a profit R(n) > C(n), thus:

12n > 135 + 4n

Subtracting 4n:

8n > 135

n > 135/8

n > 16.875

Thus, to make profits, she must sell at least 17 necklaces

Andy scores 48 out of 75 in a science test and thinks he has done better than Brandon, who has scored 65%.

No. Brandon has done better than Andy because Andy scored a 64%, when Brandon scored a 65%

Below is the graph of a trigonometric function. It intersects its midline at (3.7, 5) and again at (5.9, 5).

Flauer [41]

Answer:

4.4

Step-by-step explanation:

The parent function of this graph is: y = sin(x)

The sine function is periodic, meaning it repeats forever.

Standard form of a sine function:

$\sf f(x)= A \sin(B(x+C))+D$

where:

A = amplitude (height from the mid-line to the peak)
2π/B = period (horizontal distance between consecutive peaks)
C = phase shift (horizontal shift - positive is to the left)
D = vertical shift

The period is the horizontal distance between consecutive peaks, which is the same as twice the horizontal distance between the intersection of the curve and the mid-line.

Given consecutive points of intersection between the curve and the mid-line:

(3.7, 5)
(5.9, 5)

Therefore, the horizontal distance between these two points is:

5.9 - 3.7 = 2.2

⇒ Period = 2.2 × 2 = 4.4

-------------------------------------------------------------------------------------

To create the equation for the function.

From inspection of the given graph:

Amplitude (A) = 6
Mid-line is y = 5
Vertical shift (D) = +5

Period = 2π/B = 4.4 ⇒ B = 5π/11

Phase Shift (C) = -3.7

Substituting the values into the standard form:

$\implies \sf f(x)= 6 \sin\left(\dfrac{5}{11}\pi(x-3.7)\right)+5$

$\implies \sf f(x)= 6 \sin\left(\dfrac{5}{11} \pi x-\dfrac{37}{22}\pi \right)+5$

Can anyone help me with this and let me know how to enter this on my calculator, please? It doesn’t seem to give me the correct

Drupady [299]

Answer:

0.036

Step-by-step explanation:

The diameter is 0.6/2, which is 0.3 and your radius is 0.3.

on your calculator , you'll press 4/3 × 0.3^3

which is equals to 0.036π
