The investment amount is $37263.09.

Interest that compounded continuously to the principal amount. This interest rate provides exponential growth to period of time.

Formula of continuous compound interest rate;

P(t) = P₀ [tex]e^{rt}[/tex] , where P₀ is the principal amount, r is the interest rate and t is the time period.

Given that the Alang is going to invest with the continuous compound interest rate 5.7%.

Using the formula of continuous compound interest rate,

P(t) = P₀ [tex]e^{rt}[/tex]

P(t) = $113000 x    [tex]e^{(5.7)(5)}[/tex]

P(t) = $37263.09

If Lianne has some dimes and nickels with a total value of $4.60. The number of dimes she has is 4 more than 3 times the number of nickels then 0.15 Nickels does Lianne has.

Two or more expressions with an Equal sign is called as Equation.

Given,

Lianne has some dimes and nickels with a total value of $4.60.

The number of dimes she has is 4 more than 3 times the number of nickels.

We need to find number of nickels

From the given information

N+D=4.60

D=3N+4

N+3N+4=4.60

4N=4.60-4

4N=0.6

Divide both sides by 4

N=0.15

Hence, 0.15 Nickels does Lianne has.

The slope calculations she can use to correctly show that △PQR is a right triangle are

From the question, we have the following ordered pairs that can be used in our computation:

The vertices of △PQR are at P(-2,5), Q(-1,1), and R(7,3).

This means that

P = (-2,5),

Q = (-1,1)

R = (7,3).

The slope of the points are calculated using

slope = (y₂ - y₁)/(x₂ - x₁)

So, we have

Slope of PQ = (y₂ - y₁)/(x₂ - x₁) = (1 - 5)/(-1 - (-2)) = -4

Also, we have

Slope of QR = (y₂ - y₁)/(x₂ - x₁) = (3 - 1)/(7 - (-1)) = 2/8 = 1/4

Hence, the equations are (a) and (d)

The formula for the volume of a cone is given by the following equation:

V = 1/3 * π * r2 * h

where V is the volume of the cone, r is the radius of the cone, and h is the height of the cone.

In this case, we are given that the radius of the cone is 2.5 units and the volume of the cone is 19 cubic units. We can use this information to complete the expression that represents the height of the cone as follows:

V = 1/3 * π * r2 * h

19 cubic units = 1/3 * π * 2.5 units2 * h

19 cubic units = 1/3 * π * 6.25 units2 * h

19 cubic units = 1/3 * 19.63 units2 * h

19 cubic units = 6.54 units2 * h

h = 19 cubic units / 6.54 units2

h = 2.9 cubic units / 6.54 units

Therefore, the expression that represents the height of the cone is 2.9 cubic units / 6.54 units.

Answer:

y - 9 = 7(x - 1)

Step-by-step explanation:

The given equation is in Point Slope Form:  y - y₁ = m(x - x₁)

m is the slope, and parallel lines have the same slope (7)

x₁ and y₁ are the coordinates of a point on the line

Constant of variation for the direct function is y = [tex]\frac{2 x}5}[/tex]

Direct variation in mathematics is the general form of formula  y = k x  where x and y are variables (numbers that change) and k is a constant

Convert to slope intercept form

2x -5y =0

Add 5y to both sides

2x-5y +5y =5y

2x=5y

divide both sides by 5

[tex]\frac{2x}{5}[/tex]  =[tex]\frac{5y}{5}[/tex]

The total number of buttons they have is 4033.

A system having more than two equations is known as a system of equations.

Given that, Sebastian and Zoey had 3068 buttons, Sebastian and Valeria had 2103 buttons, and Valeria has half as many buttons as Zoey.

The equations corresponding to the statements are:

S + Z = 3068         (1)

S + V = 2103          (2)

V = Z/2                   (3)

Subtract equation (2) from equation (1):

Z - V = 965

Substitute V = Z/2 into the above equation:

Z - Z/2 = 965

Z/2 = 965

Z = 1930

Substitute Z = 1930 into equation (3):

V = 1930/2

V = 965

Substitute V = 965 into equation (2):

S + 965 = 2103

S = 1138

The total number of buttons is:
S + V + Z

= 1138 + 965 + 1930

The answer choice which must be a factor of the polynomial in discuss is; (x - 1).

It follows from the vertex form equation of a parabola; f(x) = a ( x - h )² + k where the vertex of the parabola is; (h, k).

Therefore, the equation of the parabola in discuss is;

f(x) = a (x - 3.5)² + 3.

Recall that the x coordinates of the vertex, h is given by; h = (p + q) / 2

where p and q are the zeroes of the quadratic function.

Therefore, since one of the zeroes is given as; 6 ( from (6, 0) ); it follows that the second zero can be determined as follows;

3.5 = ( 6 + q ) / 2

What is slope of line?

Slope of line is defined as the angle of line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂).

If the product of slopes of any two sides is equal to -1, then those two sides are perpendicular

Given,

The vertices of △PQR are at P(-2,5), Q(-1,1), and R(7,3).

Slope of PQ = (y₂ - y₁)/(x₂ -x₁ )

1. An equation that finds the number of car washes for which the costs of Plan A and Plan B are the same is 12n = 16 + 8n.

2. The solution of the equation shows that the number of car washes for which the cost of each plan is the same is 4.

Equations are mathematical statements claiming that two or more mathematical expressions are equal or equivalent when solved.

Equations use numbers, constants, variables, and the equation symbol (=) to depict the equality of the mathematical expressions.

                                 Plan A     Plan B

Cost per cash wash  $12           $8

Fixed cost                  $0           $16

Mathematical Expressions for the Carwash Plans:

Let Plan A = 0 + 12n

Let Plan B = 16 + 8n

The number of car washes when the two plans' costs are equal can be derived by equating the two mathematical expressions above:

12n = 16 + 8n

12n - 8n = 16

4n = 16

n = 4

= 4 car washes

Check:

Plan A = 0 + 12n

= 12(4)

= 48

= $48

Plan B = 16 + 8n

= 16 + 8(4)

= 16 + 32

= 48

= $48

Thus, solving the equation, we can conclude that choosing Plan B will take 4 car washes to equal the cost of Plan A.

The function of reflect x-axis is g(x) =  -(1/2)*x - 8, according to the question.

What do you mean by function?

A function in mathematics from a set X to a set Y assigns exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.

According to the given question,

First, let's define a reflection over the x-axis.

If we have a point (x, y) and we reflect it over the x-axis, our new point will be (x, -y).

Now, when we have a function

f(x) = y, the points can be written as:

(x, y = f(x) ) = (x, f(x))

Then, after the reflection over the x-axis, we have:

(x, y = g(x)) = (x, -f(x))

So now we have g(x) = -f(x)

and we know that f(x) = (1/2)*x + 8

then our new function is g(x) =  y = -f(x) = -( (1/2)*x + 8) = -(1/2)*x - 8.

g(x) =  -(1/2)*x - 8.

Therefore, the required answer is g(x) =  -(1/2)*x - 8.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

The system of equations:

y = -3x - 1

y = x² - 3x + 4

x² - 3x + 4 = 0

It is in the form of ax² + bx + c = 0

a = 1, b = -3, and c = 4

Now,

x = -b ± √(b² - 4ac) / 4a

x = 3 ± √(9 - 16) / 4

x = 3 ±√-7 / 4

x = 3 ±i√7 / 4
