Multiply the x by 4, then add 3. ( 4× $\frac{1}{2}$ +3= 5 ). Keep doing that for the rest. Hope this helped a little. If you have any questions, you can message me if you would like.

Prove or disprove that (1)/(1-cot x) is the same as (sin x)/(sin x - cos x)

SIZIF [17.4K]

$\dfrac{1}{1-\cot x}=\dfrac{\sin x}{\sin x-\cos x}\\\\L_s=\dfrac{1}{1-\dfrac{\cos x}{\sin x}}=\dfrac{1}{\dfrac{\sin x}{\sin x}-\dfrac{\cos x}{\sin x}}=\dfrac{1}{\dfrac{\sin x-\cos x}{\sin x}}=\dfrac{\sin x}{\sin x-\cos x}=R_s$

$\text{Used:}\\\\\cot x=\dfrac{\cos x}{\sin x}$

Write the equation of the line that passes through (0,-6) and (4,10)

LenaWriter [7]

Answer:

y=4x-6

Step-by-step explanation:

to find the slope it's ((y1-y2)/(x1-x2) which in this case is (10-(-6))/(4-0) which is 16/4 aka 4

the y intercept is already given at point (0,-6)

so to write the equation is y intercept form: its y =4x-6

Name the property shown by the statement. (8 + 7) + 3 = 8 + (7 + 3)

Evgen [1.6K]

Step-by-step explanation:

Associative Property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped', I mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis. Example: 3+(2-4) can be rewritten as (3+2)-4.

hope it helps!

The average cost per unit for the production of a certain brand of DVD is given by C=\frac{500+60c+0.01x^2}{x} , where x is the

Ganezh [65]

Answer:

A: for 500: 66; for 60: 68.9; for 100: 66

B: no

Step-by-step explanation:

We assume your average cost function is ...

$\overline{C}=\dfrac{0.01x^2+60x+500}{x}$

A. The overline over the C indicates it is an average value.

Evaluating the cost function at the different production levels, we find the average cost per unit to be ...

500 units

c = ((0.01·500)+60)500 +500)/500 = 65 +1 = 66

60 units

c = ((0.01·60 +60)·60 +500)/60 = 60.6 +500/60 ≈ 68.93

100 units

c = ((0.01·100 +60)·100 +500)/100 = 61 +5 = 66

B. Dividing out the fraction, we find that the cost per unit is ...

0.01x +60 +500/x

As x gets large, this approaches the linear function c = 0.01x +60. This increases as the number of units produced rises. (The minimum average cost is at a production level of about 224 units.)
