Using the Fundamental Counting Theorem, there are 240 ways to choose general education courses from these 4 areas.

It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:

[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]

Considering the number of options for each course, the parameters are given as follows:

[tex]n_1 = 5, n_2 = 4, n_3 = 4, n_4 = 3[/tex].

Hence the number of ways is given by:

N = 5 x 4 x 4 x 3 = 240.

The percent that the cost price is less than the marked price will be 40%.

Let the cost price be 100.

Since the marked price of an article is 40% above the cost price, the marked price is 140.

The percent that the cost price is less than the marked price will be:

= 140 - 100

Answer:  A rose bush, r, cost $8; one pot of ivy, i, cost $6;

Step-by-step explanation:

[tex]\left \{ {{5r + 3i =58} \atop {5r+10i=100}} \right.[/tex]

We combine them by minus, we get:

    5r + 3i = 58

-    5r + 10i = 100

           - 7i = - 42

               i = 6

We plug in i = 6 to the first equation, we get:

     5r + 3(6) = 58

        5r + 18 = 58

                5r = 40

                  r = 8

The cost of one rose bush is $8 and the cost of one pot of ivy is $6.

Here are the equations to represent the scenario:

Micaela: 5r + 3i = 58

Chelsea: 5r + 10i = 100

Let's solve the system of equations to find the cost of one rose bush (r) and one pot of ivy (i).

Subtracting the first equation from the second equation, we get:

7i = 42

Dividing both sides by 7 we get:

i = 6

The rose bushes will be:

5r + 3i = 58

5r + 18 = 58

5r = 58 - 18

5r = 40.

r = 8

This means that the cost of one rose bush is $8 and the cost of one pot of ivy is $6.

The simplified function of [tex]f(x) = \frac 14(\sqrt[3]{108^x})[/tex] is [tex]f(x) = \frac {3^x}4(\sqrt[3]{4})^x[/tex]

The function is given as:

f(x) = 2x²-x-10

a= 2

b= -1

c = -10

-b/2a

-(-1)/(2(2))

1/4

x = 1/4

f(x) = 2x²-x-10

y = 2x²-x-10

y = 2(1/4)²-(1/4)-10

y = 2/16-1/4-10

y = 2/16-4/16-160/16

y = -2/16-160/16

y = -162/16

y = -81/8

The expression that can be used to find the area of the tiled floor is 4w² + 200w

Length = 70 Meters

Width = 30 meters

Area = length × width

= 70 × 30

= 2100

Length = 70 + 2w meters

Width = 30 + 2w meters

Area = length × width

= (70+2w) (30+2w)

= 2100 + 140w + 60w + 4w²

= 4w² + 200w + 2100

Area of the tiled floor = Area of new rectangle - area of old rectangle

= (4w² + 200w + 2100) - 2100

The exact values of the remaining trigonometric functions are sin(x) = -7/25 and tan(x)= -7/24

The function is given as:

cos(x) = 24/25, tan(x) < 0

The sine function is calculated using:

sin^2(x) + cos^2(x) = 1

So, we have:

sin^2(x) + (24/25)^2 = 1

Collect like terms

sin^2(x) = -(24/25)^2 + 1

Evaluate the squares

sin^2(x) = -576/625 + 1

Take the LCM

sin^2(x) = (625-576)/625

Evaluate

sin^2(x) = 49/625

Take the square roots

sin(x) = -7/25 --- sin(x) is negative because tan(x) < 0

The tangent function is calculated using:

tan(x) = sin(x)/cos(x)

This gives

tan(x) = (-7/25) / (24/25)

Evaluate

tan(x)= -7/24

Hence, the exact values of the remaining trigonometric functions are sin(x) = -7/25 and tan(x)= -7/24
