is (2,5),(3,6),(6,9) a function

By taking x as subject the formula becomes x = (v² - u²)/2a.

An equation is a mathematical statement with an 'equal to=' symbol between two expressions that have equal values.

Here given equation:

      v² = u² + 2ax

     2ax = v² - u²

      x = (v² - u²)/2a

Thus, by taking x as subject the formula becomes x = (v² - u²)/2a.

Answer:

It is a Scalene Right triangle

The expression that would be added to both sides is (b/2a)^2

The equation is given as:

x^2 + b/ax + __ = c/a + __

Take the coefficient of x

b/a

Divide by 2

b/2a

Square the expression

(b/2a)^2

Hence, the expression that would be added to both sides is (b/2a)^2

Answer:

11.31

Step-by-step explanation:

The diameter of the circle is 3.6 units.

Value of "a"

Circumference of a circle in terms of radius:
Circumference = 2 · π · r = 2 · 3.14 · 1.8 = 11.31 (*)

In terms of diameter:

Circumference = π · d = 3.14 · 3.6 = 11.3 (*)

In terms of area:

Circumference C = √4·π·A = √4·π·10.18 = 11.31 (*)

The marginal demand to estimate the change in demand when the price is increased by one dollar is -157.

Given, [tex]D(p)=-4p^2+3p+8,[/tex] where p represents the price of the item in dollars.

Currently, the price of the item is $20.

In economics, marginal demand refers to the shift in demand for a product or service in reaction to a price adjustment. Normally, as the price of a good or service rises, demand decreases, and vice versa, as the price of a good or service decreases, demand increases.

We have to use the marginal demand to estimate the change in demand when the price is increased by one dollar.

The rate of change of demand with respect to price is obtained by differentiating D with respect to p in [tex]D(p)=-4p^2+3p+8[/tex].

That is, dD/dp = -8p+3

Given, p = $20

dD/dp = -8×20+3=-157

Therefore, the marginal demand to estimate the change in demand when the price is increased by one dollar is -157.

Answer:

9/5x

Step-by-step explanation:

Let a variable stand for the nonzero number. It has to not be zero because it's on the bottom of a fraction or it is the "divided by" guy in a division. It is division because quotient means you are dividing.

So 9 is on top (or in front)

5x is on the bottom (or the second term)

9/5x

also 9÷5x but I think the / notation is preferred in middle school, high school and college for algebra.

Also the variable can be almost any letter, like 9/5n or 9/5s is just as good.

Probability of mango in first basket is = 3/10

Answer:

Step-by-step explanation:

So, you are given an equation with two variables. Normally, you'd need two equations to solve this, but in this case we are given the value for one of the variables two times, so this is quite simple once you understand it.

Our first solution set is given as (9,?). This means we must find what y is equal to. To do this, we simply fill in the given x value (9) and equate to y as follows:

2x + 3y = 12

⇒ 2 · 9 + 3y = 12

⇒ 3y = 12 - 2 · 9 = -6

⇒ y = -6/3 = -2

Thus, the first solution is (9,-2). If we check to see if this is correct we find that 2·9 + 3·(-2) = 18 - 6 = 12 and indeed it is correct. For the next one, we are given the value for y and can thus equate to x:

2x + 3y = 12

⇒ 2x + 3 · 4 = 12

⇒ 2x = 12 - 3 · 4 = 0

⇒ x = 0/2 = 0

And the second solution set is then (0,4).
Check to be sure: 2·0 + 3·4 = 0 + 12 = 12 , yes indeed it is.

The net percentage lost on the stock is 4%

Let the value of the stock be represented with x.

When it goes down by 20% on Monday, the value is:

Value = (1 - 20%) * x

Value = 0.8x

When it goes up by 20% on Tuesday, the value is:

Value = (1 + 20%) * 0.8x

Value = 0.96x

Recall that the initial value is x.

So, the profit is:

Profit = 0.96x - x

Evaluate the difference

Profit = -0.04x

Express as percentage

Profit = -4%x

Negative value represent a percentage lost.

Hence, the net percentage lost is 4%

By applying the features of polynomials, the quadratic function g(x) = (1/5) · x² - 2 · x + 21/5 passes through the points (x₁, y₁) = (-8, 33), (x₂, y₂) = (2, 1) and (x₃, y₃) = (8, 1).

Polynomials are algebraic expressions of the form [tex]\sum \limits_{i=0}^{n} c_{i}\cdot x^{i}[/tex], where [tex]c_{i}[/tex] is the i-th coefficient of the polynomial and n is the grade of the polynomial. In addition, we know that polynomials have n + 1 coefficients.

In the case of quadratic functions, the grade is 2 and the function have three coefficients. Hence, we need three distinct points to determine all the coefficients of a quadratic function.

(x₁, y₁) = (-8, 33)

64 · a - 8 · b + c = 33     (1)

(x₂, y₂) = (2, 1)

4 · a + 2 · b + c = 1     (2)

(x₃, y₃) = (8, 1)

64 · a + 8 · b + c = 1     (3)

Then, we find the solution of this system of linear equations:

a = 1/5, b = -2, c = 21/5

By applying the features of polynomials, the quadratic function g(x) = (1/5) · x² - 2 · x + 21/5 passes through the points (x₁, y₁) = (-8, 33), (x₂, y₂) = (2, 1) and (x₃, y₃) = (8, 1).
