The piecewise function for the discounted price of the purchase is given by:

A piecewise function is a function that has different definitions, depending on the input.

For $300≤x<$1,000, the discount is of 4%, hence the discounted price is 96% of the original price, that is:

D(x) = 0.96x, 300≤x<1,000

For $1,000≤x<$3,000, the discount is of 5%, hence the discounted price is 95% of the original price, that is:

D(x) = 0.95x, 1,000≤x<3,000.

For $3,000≤x<$5,000, the discount is of 6%, hence the discounted price is 94% of the original price, that is:

D(x) = 0.94x, 3,000≤x<5,000.

For $5,000≤x, the discount is of 10%, hence the discounted price is 90% of the original price, that is:

D(x) = 0.9x, 5,000≤x.

The approximate total amount of felt used in the logo is 334.34 square cm

We have the following parameters on the logo:

Shapes = Semicircle and Triangle

Where

Semicircle:

Diameter = 18 cm

Triangle

Base = 16 cm

Height = 10 cm

The approximate total amount of felt used in the logo is calculated as

Amount = Area of semi-circle + Area of triangle

This gives

Amount = π(d/2)^2 + 0.5bh

So, we have

Amount = 3.14 * (18/2)^2 + 0.5 * 16 * 10

Evaluate

Amount = 334.34

Hence, the approximate total amount of felt used in the logo is 334.34 square cm

The constant of proportionality is 3 for the ratio of robins to cardinals.

We have a table:

Cardinals        Robins

5                      15

6                      18

9                       27

10                      30

We need to find the constant of proportionality.

The constant of proportionality is the ratio that relates two given values in what is known as a proportional relationship.

We know that:

Robins ∝ Cardinals

Robins = K × Cardinals

K = the constant of proportionality

15 = k (5)

k = 3

So, we get the constant of proportionality as 3.

Therefore, the constant of proportionality is 3 for the ratio of robins to cardinals.

Answer: (x-3)(x-5) = x2 - 8x + 15

The roots will be unchanged by multiplication by 3: 3x2 - 24x + 45

Step-by-step explanation:

Answer:

y = 3x² + 6x - 45

Step-by-step explanation:

given roots x = a and x = b then the factors are (x - a) and (x - b)

then the quadratic is the product of its factors

y = a(x - a)(x - b) ← a is a multiplier

here x = - 5 and x = 3 with a = 3 , then factors are

(x - (- 5)) and (x - 3) , that is (x + 5) and (x - 3) , then

y = 3(x - 3)(x + 5) ← expand factors using FOIL

y = 3(x² + 2x - 15) ← distribute parenthesis by 3

y = 3x² + 6x - 45

Answer:

the third one (the outmost right)

Step-by-step explanation:

the first one goes from -2 to 0 through functional values of 0, down to -5, and then back up to 0. so, it does NOT go down between -2 and 0.

the second one goes from -2 to 0 through the functional values of -15 up to -5. so, it goes UP in that interval.

and the third one goes from -2 to 0 through the functional values of 0 down to -10 and then further down to -24. so, this one is truly decreasing in that interval.

The value of the given expression after simplification is 12.16

Expression:        

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is called an expression or an algebraic expression.

Simplification:

The act of substituting a complex mathematical expression with a simpler counterpart is known as simplification (usually shorter).

Simplifying the given expression i.e.(2)(2.3) + (3.14)(4) - 5

⇒(2)(2.3) + (3.14)(4) - 5

⇒4.6 + 12.56 - 5

⇒17.16 - 5

⇒12.16        

⇒(2)(2.3) + (3.14)(4) - 5 = 12.16

From division it is possible to find x= -4.

An equation can be represented by a linear function. The standard form for the linear equation is: y= ax+b , for example, y=7x+2. Where:

a= the slope. It can be calculated for [tex]a=\frac{\Delta y}{\Delta x}[/tex] .

b= the constant term that represents the y-intercept.

For the given example: a=7 and b=2.

For solving  linear equations, you should organize variables on one side of the equation and the numbers on the other side. When a number or variables change side, its signal also is changed.

Therefore for -12x=48, you should follow the steps below

-12x=48

a = 1, b = 2 is a counterexample, and with that, we conclude that the conjecture is false.

Here we have the conjecture:

"For any two integers a and b, (a - b)^2 = (a^2 - b^2)"

Notice that if we find a single pair of integers a and b such that the equality in the conjecture is false, then we have found a counterexample and that is enough to conclude that the conjecture is false.

If we define=

a = 1

b = 2

Replacing that in the equation of the conjecture we get:

(1 - 2)^2 = (1^2 - 2^2)

(-1)^2 = 1 - 4

1 = -3

This is false, then a = 1, b = 2 is a counterexample, and with that we conclude that the conjecture is false.

The total value will be given by the linear equation:

y = x*25 + (x + 2)*10 + (2x)*5

Where y represents the total value in cents.

Now we can simplify that equation to get:
