There are 720 ways that the 3 homes could be chosen if the order of visiting is considered. There are 120 ways that the 3 homes could be chosen if the order of visiting is not important.

A permutation is the arrangement or ordering of a finite set of an element.

From the information given:

If there are  10 homes in the desired price range listed in the area:

Then:

So, the number of ways of choosing 3 out of 10 (without replacement) and arranging is:

[tex]\mathbf{^nP_r= \dfrac{n!}{(n-r)!}}[/tex]

[tex]\mathbf{^nP_r= \dfrac{10!}{(10-3)!}}[/tex]

[tex]\mathbf{^nP_r= \dfrac{10\times 9\times 8 \times 7!}{(7)!}}[/tex]

= 720 ways

Now, the number of ways of choosing 3 out of 10 if the order of visiting is not important is the combination of the elements and it can be computed as:

[tex]\mathbf{^nC_r= \dfrac{n!}{(n-r)!r!}}[/tex]

[tex]\mathbf{^{10}C_3= \dfrac{10!}{(10-3)!3!}}[/tex]

[tex]\mathbf{\implies \dfrac{10\times 8\times 9 \times 7!}{(7)! \times 3\times 2}}[/tex]

[tex]\mathbf{\implies \dfrac{10\times 8\times 9}{6}}[/tex]

= 120 ways

An equation is formed of two equal expressions. Julian should invest $160,000 in CD and $640,000 in Bond.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the amount invested in CD be represented by x, while the amount invested in bond be represented by y. The total amount that Julian had is,

x + y = 800,000

x = 800,000 - y

The interest that Julian needs in a year is $36,000. Therefore, the total interest should be,

0.025x + 0.05y = 36000

0.025(800,000 - y) + 0.05y = 36000

20,000 - 0.025y + 0.05y =36,000

0.025y = 16,000

y = $640,000

Substitute the value of y

x + y = 800,000

x = $160,000

Hence, Julian should invest $160,000 in CD and $640,000 in Bond.

Answer:

simple interest

Step-by-step explanation:

this is because r is interest rate, p is principal, and t is time

Answer:

simple interest

Step-by-step explanation:

Simple interest rate is defined as: I = p * r * t. So you're taking the principle amount (initial amount loaned) and multiply it by the interest rate. This gives you the interest rate in a year (usually, depends on time unit of t). Generally speaking, it gives you the interest over a specific amount of time. Now multiply it by the amount of time that's passed. So you're just calculating the total amount of interest. So the I stands for the simple interest.

Answer: A

Step-by-step explanation:

This is a fact.

The absolute value parent or modulus function is f ( x ) = | x |

Regardless of the sign, a modulus function returns the magnitude of a number. The absolute value function is another name for it.

It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.

The value of the modulus function is always non-negative. If f(x) is a modulus function , then we have:

If x is positive, then f(x) = x

If x = 0, then f(x) = 0

If x < 0, then f(x) = -x

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = | x |

The absolute value parent function is f(x) = |x|, which represents the absolute value of x.

Option B, f(x) = 13x1, does not represent the absolute value function, as it has a coefficient of 13, which scales the function vertically.

Option C, f(x) = x-− 1|, represents a translation of the absolute value function. The "-1" shifts the function one unit to the right, and the vertical bar denotes the absolute value of the expression within the bar. While it is related to the absolute value function, it is not the parent function itself.

Option D, f(x) = x+2, represents a linear function with a slope of 1, which is not the absolute value function.

Hence , the absolute value parent function is f ( x ) = | x |

Using the trigonometric ratios, the measures are:

a. z = 222.5 ft

b. h = 38.6 ft.

c. b = 10.4 ft

d. B = 219.1 ft.

The ratios of trigonometry that can be used to solve a right triangle are:

sin ∅ = opp/hyp

cos ∅ = adj/hyp

tan ∅ = opp/adj.

a. Find h using the sin ∅ = opp/hyp:

sin 75 = opp/hyp = h/40

h = (sin 75)(40) = 38.6

Find z using the sin ∅ = opp/hyp

sin 10 = opp/hyp = 38.6/z

z = 38.6/sin 10

z = 222.5 ft. (length of the zip line)

b. Height of the tree = h = 38.6 ft.

c. Using sin ∅ = opp/hyp, find b (distance between the base of the ladder and the base of the tree):

sin 15 = b/40

b = (sin 15)(40)

b = 10.4 ft

d. Using sin ∅ = opp/hyp, find B as shown in the image:

sin 80 = opp/hyp = B/222.5

B = (sin 80)(222.5)

B = 219.1 ft.

Triangle RST was transformed by using the rule (x,y) → (-x,-y) and the transformation is described by the transformation of 180° rotation about the origin.

Transform the shapes on a coordinate plane by rotating, reflecting, or translating them. Here we have transformed the triangle using the rotation method.

Rotation is the geometric transformation that revolves each point in a shape a predetermined number of degrees around that point. When the number of degrees is positive, the shape spins counterclockwise; when the number of degrees is negative, it rotates clockwise. The following is a broad description of how rotation about the origin can be transformed.

Here the points change to R'(-1,-1) , S'(-3,-1) and T'(-1,-6).

A 180° rotation about the origin will be the transformation.

The triangles RST and R'S'T' are first plotted on a graph. The graph is provided for your reference below.

The original triangle RST, which was in quadrant 1, has changed to triangle R'S'T', which is in quadrant 3, as shown in the graph. The rotation around the origin is 180° from quadrant 1 to quadrant 3.

Your question was incomplete. Please check below for full content.

Answer:

x = 0 or x = 1

Step-by-step explanation:

f(x) = |x| - 4

g(x) = x³ - 4

f(x) = g(x)

|x| - 4 = x³ - 4

Add 4 to both sides.

|x| = x³

x = x³  or  -x = x³

x³ - x = 0   or   x³ + x = 0

x(x² - 1) =   or  x(x² + 1) = 0

x = 0 or x + 1 = 0 or x - 1 = 0

x = 0 or x = -1 or x = 1

x = -1 does not work, so we discard that solution.

Answer: x = 0 or x = 1

Answer:

values of x: x = 1 and x = 0

Step-by-step explanation:

Given:

Want: x - values when f(x) = g(x)

|x| - 4 = x³ - 4, the 4 cancel out on both sides

|x| = x³

|x| - x³ = x³ - x³

|x| - x³ = 0, x ≥ 0

-x - x³ = 0, x < 0
