What is the measure of an angel that turns through 3/4 of a complete circle?

1 answer:

6 0

2/3 think of this as a pie right divided into 3 area but only 2 people eat from it 1 left but how would i complete it if its not done well i need to complete the "pie"
by adding an exponent into the mesure and cacultating a mass of a=mx+b
now you divide and get 0.75
so you will fill in .25 more to get the full measurement by eating 1 more pie:

HI can you help me with this problem?The quantity demanded x for a certain brand of MP3 players is 300 units when the unit price

Vlad [161]

The demand equation is P = -0.05x + 105

STEP - BY - STEP EXPLANATION

What to find?

<em>The demand equation.</em>

The following information is used to solve the problem.

If (x₁ , y₁) and (x₂, y₂) are any dinstinct points on a line a non-vertical line L, then the equation of the line that has a slope(m) and passes through the point (x₁ , y₁) is given by the formula below:

$y-y_1=_{}\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Assume p, be the unit price and x be the demand when the price is $p.

From the question given, when the unit price x = 300 units, the demand p = $90 and when the unit price x = 1300 units, the demand p = $40

This means the demand curve passes through the points (300, 90) and (1300, 40).

Assume the demand equation is linear, then the line of the equation passes through the points (300, 90) and (1300, 40).

Now;

y=p x₁ =300 y₁ = 90 x₂ = 1300 y₂=40

Substitute the values into the function and simplify.

$p-90=\frac{40-90}{1300-300}(x-300)$

Simplify the above.

$p-90=\frac{-50}{1000}(x-300)$ $p-90=-0.05(x-300)$

Open the parenthesis.

P- 90 = -0.05x + 15

Add 90 to both-side of the equation.

P = -0.05x + 15 + 90

P = -0.05x + 105

Hence, the demand function is P = -0.05x + 105

Write a system of equations with the solution (4,-3)

Slav-nsk [51]

Answer:

y = 3x-15 and y = x-7

Step-by-step explanation:

We are asked to write a system of equations with the solution (4,-3)

It is sufficient if we find two lines passing through this point.

Let us take first line as with slope 3.

Then the equation would be of the form

y-y1 = m(x-x1)

y+3 = 3(x-4)

Or y = 3x-15 is one line

Let second line have slope 1

y+3 = 1(x-4)

y = x-7

Now we have two systems of equations as

y = 3x-15 and y = x-7
