Angela is buying a dress that is on sale for 20% off. If the original price of the dress is $50.00, how much money is Angela saving on the dress?

Answer:

the difference between these two numbers is 85.29

Answer: 85.29

Step-by-step explanation:

difference means to subtract

Eddie's account can be modelled as a linear function.

Ely's account can be modelled as an exponential function.

Ely's account  would be higher than Eddie's account by $207.98.

A linear function is a function that has one variable that is raised to the power of 1. An example is 5x + 2.

Eddie's account can be modelled as a linear function because it increases by $240 every year. The linear function is $3000 + $240x. Where x is the number of years.

An exponential function is a function that is in the form y = [tex]a^{x}[/tex].

Ely's account can be modelled as an exponential function because it increases by [tex]1.08^{x}[/tex]. The exponential function is $3000 x  [tex]1.08^{x}[/tex]. Where x is the number of years.

Value of Eddie's account in 5 years = $3000 + $240(5) = $4,200

Value of Ely's account in 5 years = $3000 x  [tex]1.08^{5}[/tex] = $4,407.98.

Difference = $4,407.98 - $4,200 = $207.98

The table is an illustration of a linear and an exponential function.

From the table, we can see that Eddie's balance increase by 240 each month.

This represents a linear function.

Also, we can see that Ely's balance increases at a rate of 8% each month.

This represents an exponential function.

So, we have:

[tex]y = 3000 + 240x[/tex] -- Eddie's account

[tex]y = 3000(1.08)^x[/tex] --- Ely's account

In (a), we have:

[tex]y = 3000 + 240x[/tex] -- Eddie's account

[tex]y = 3000(1.08)^x[/tex] --- Ely's account

So, their balance in 5 years is:

[tex]y =3000 + 240*5[/tex]

[tex]y =4200[/tex]

[tex]y = 3000(1.08)^5[/tex]

[tex]y = 4408[/tex]

Calculate the difference (d)

[tex]d = 4408 - 4200[/tex]

[tex]d = 208[/tex]

Hence, Ely's balance would be $208 greater than Eddie's

180 clockwise Hope it helps!

Step-by-step explanation:

The type of rotation that is shown in the plane coordinates above is the 180 degrees clockwise turn.

This is due to the new position that the plane coordinate has taken. It has gone from Q, R to -Q,-R when we look closely at the new plane.

The angles have changed through the rotation of the plane to what seems like a counter image.

Step-by-step explanation:

Using the rule of logarithms

[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]

let

[tex]log_{2}[/tex] 8 = n ⇒ 8 = [tex]2^{n}[/tex] , that is

2³ = [tex]2^{n}[/tex] ( equate exponents )

n = 3

and let

[tex]log_{3}[/tex] ( [tex]\frac{1}{3}[/tex] ) = n ⇒ [tex]\frac{1}{3}[/tex] = [tex]3^{n}[/tex] , that is

[tex]3^{-1}[/tex] = [tex]3^{n}[/tex] ( equate exponents )

n = - 1

Answer:

A = (81 - 20.25π)cm²

P = (18 + 9π)cm

Step-by-step explanation:

Since the answer asks for the exact value, we will keep π as itself to ensure there is no rounding off errors.

Firstly, finding the area A.

> Putting both semicircles together, you will get a full circle. Hence, finding the area only requires you to subtract the circle off the square.

>Also, the radius of the circle is [tex]\frac{9}{2}=4.5[/tex].

Thus,

[tex]A=9^{2} -(\pi *4.5^{2} )\\A= 9^{2}-20.25\pi\\A= (81-20.25\pi)cm^{2}[/tex]

Next, finding the perimeter B.

>Again, combining both arcs of the shaded figure together, we form a circumference of the circle.

Thus,

[tex]P = 2(9) + (2*\pi *4.5)\\=(18+9\pi )cm[/tex]

Step-by-step explanation:

there must be some additional information missing (like the domain of the function), because just as it is written here, the function f(x) would not have any limitations, and its range would be -infinity < y < +infinity.

so, it is impossible to tell you which answer option is correct.

because again, based on the given information, none of these options is correct.
