We calculate P to be approximately $7,759.58, which is the amount Ryan invested initially.
To determine the initial investment that Ryan made, which grew to $12,835.94 after 10 years with an annual interest rate of 4.31% compounded monthly, we will use the formula for compound interest:
[tex]A = P(1 + r/n)^{nt}[/tex]
Where:
A is the amount of money accumulated after n years, including interest.
P is the principal amount (the initial amount of money).
r is the annual interest rate (decimal).
n is the number of times that interest is compounded per year.
t is the time the money is invested for, in years.
We know that:
A = $12,835.94
r = 4.31/100 = 0.0431
n = 12
t = 10
We need to solve for P:
P = A /[tex](1 + r/n)^{nt}[/tex]
Substituting the known values, we get:
P =[tex]$12,835.94 / (1 + 0.0431/12)^{12*10}[/tex]
P = $12,835.94 / [tex](1 + 0.0035925)^{120}[/tex]
P = $12,835.94 / ([tex]1.0035925)^{120}[/tex]
Calculating the value inside the parenthesis first:
[tex](1.0035925)^{120}[/tex] = 1.654297553
Now, we divide the final amount by this compound factor:
P = $12,835.94 / 1.654297553
P ≈ $7,759.58
Therefore, Ryan's initial investment was approximately $7,759.58.

The percent of the discount in the problem above is 15%. What percent of the original bill is Chumani's bill? How could you solve the problem using this percent?
Chumani's bill represents 85% of the original bill after a 15% discount is applied. The discounted amount can be found by multiplying the original bill by 0.85.
If the discount on an item is 15%, and Chumani is paying after this discount has been applied, we want to find out what percent of the original bill Chumani's bill is. To do this, we subtract the discount rate from 100%. So, 100% - 15% = 85%. Thus, Chumani's bill is 85% of the original bill.
To calculate the discounted bill, you multiply the original bill amount by 0.85 (which represents 85%). If the original bill was, for example, $100, the calculation would be $100 x 0.85 = $85. So, Chumani would pay $85, which is 85% of the original bill amount.

Find the x value for point C such that AC and BC form a 2:3 ratio.
A) 6
B) −0.6
C) 4
D) −2.4
The x value for point C is not one of the given options.
Explanation:To find the x value for point C such that AC and BC form a 2:3 ratio, we first need to find the coordinates of point C. The given components are Cx = -2/3, Cy = -4/3, and C₂ = 7/3. Substituting these values into Equation 2.21, we get:
C = sqrt((-2/3)² + (-4/3)² + (7/3)²) = sqrt(23/3)
Therefore, the x value for point C is not one of the options given. None of the options (A) 6, (B) -0.6, (C) 4, or (D) -2.4 are correct.
Final answer:
To find the x value for point C such that AC and BC form a 2:3 ratio, substitute the coordinates of point C into the equation and solve for C.
Explanation:
To find the x value for point C such that AC and BC form a 2:3 ratio, we can use the coordinates of points A, B, and C. We have Cx = -2/3, Cy = -4/3, and C₂ = 7/3. Substituting these values into Equation 2.21 gives:
C = √((-2/3)² + (-4/3)² + (7/3)²) = √(4/9 + 16/9 + 49/9) = √(69/9).
So the x value for point C is √(69/9).
Amare wants to ride a Ferris wheel that sits four meters above the ground and has a diameter of 50 meters. It takes six minutes to do three revolutions on the Ferris wheel. Complete the function, h(t), which models Amare's height above the ground, in meters, as a function of time, t, in minutes. Assume he enters the ride at the low point when t = 0.
The complete function that models Amare's height above the ground, h(t), as a function of time, t, in minutes is:
h(t) = 25 · sin((π / 3) t) + 4
To model Amare's height above the ground, use the equation of a sinusoidal function.
In this case, since the Ferris wheel has a diameter of 50 meters, the amplitude of the function is half of the diameter, which is 25 meters. The Ferris wheel completes three revolutions in six minutes, so the period of the function is 6 minutes.
The equation for the height function is given by:
h(t) = A · sin((2π / T) t + φ) + h0
Where:
A is the amplitude (25 meters)
T is the period (6 minutes)
φ is the phase shift (0 radians, since Amare enters at the low point)
h0 is the vertical shift (4 meters, since the Ferris wheel sits four meters above the ground)
Substitute the given values into the equation
h(t) = 25 · sin((2π / 6) t + 0) + 4
Simplifying further:
h(t) = 25 · sin((π / 3) t) + 4
Therefore, the complete function that models Amare's height above the ground, h(t), as a function of time, t, in minutes is:
h(t) = 25 · sin((π / 3) t) + 4

Sara has 20 sweets.
12 liquorice, 5 mint, 3 humbug.
Sara is going to take at random two sweets.
work out the probability that the two sweets will not be the same type. Give your answer as a fraction
Answer:
111/190
Step-by-step explanation:i know you dont want to see explanation so yeah...
Probabilities are used to determine the chances of an event.
The probability that the two selected sweet will not be of the same type is [tex]\frac{111}{190}[/tex]
The given parameters are:
[tex]n = 20[/tex] --- number of sweet
[tex]L = 12[/tex]
[tex]M = 5[/tex]
[tex]H = 3[/tex]
First, we calculate the probability that the two selected sweet will be of the same type.
This is calculated as:
[tex]P(Same) =P(L\ and\ L) + P(M\ and\ M) + P(H\ and\ H)[/tex]
Because the selection is without replacement, the equation becomes
[tex]P(Same) = \frac{12 \times 11}{20 \times 19} +\frac{5 \times 4}{20 \times 19} + \frac{3 \times 2}{20 \times 19}[/tex]
[tex]P(Same) = \frac{132}{380} +\frac{20}{380} + \frac{6}{380}[/tex]
Add fractions
[tex]P(Same) = \frac{132+20+6}{380}[/tex]
[tex]P(Same) = \frac{158}{380}[/tex]
Using the complement rule, the probability that the two selected sweet will not be of the same type is:
[tex]P(Not\ same) = 1 - P(Same)[/tex]
This gives
[tex]P(Not\ same) = 1 - \frac{158}{380}[/tex]
Take LCM
[tex]P(Not\ same) = \frac{380 - 158}{380}[/tex]
[tex]P(Not\ same) = \frac{222}{380}[/tex]
Simplify
[tex]P(Not\ same) = \frac{111}{190}[/tex]
Hence, the required probability is: [tex]\frac{111}{190}[/tex]

Triangle ABC has vertices at (2,2), (4,3), and (6,1).
Using triangle ABC as the pre-image and origin as the center of dilation, what are the coordinates of a dilation of these vertices that uses a scale factor of 0.5?
A. (10,10)(20,15)(30,5)
B. (-1,-1)(-2,-15)(-3,-0.5)
C. (1,1)(1.5,2)(0.5,3)
D. (1,1)(2,1.5)(3,0.5)
Answer:
The correct answer is D.
Step-by-step explanation:
Recall that when we make a dilation with center at the origin, the only needed operation is to multiply the coordinates of each point by the factor of dilation. In this particular case the dilation factor is 0.5 so we must do the following operations:
0.5*(2,2) = (0.5*2,0.5*2) = (1,1)0.5*(4,3) = (0.5*4,0.5*3) = (2,1.5)0.5*(6,1) = (0.5*6, 0.5*1) = (3,0.5)So, the vertices of the triangle after the dilation are those who appear in D.

The simplified expression of (r⁴ - r² + 4) ÷ (r² - r + 2) is r³ -r+ 4/r ÷ r - 1 + 2/r
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is (r⁴ - r² + 4) ÷ (r² - r + 2)
r power four minus r square plus four divided by r square minus r plus two.
The expression can not be simplified further as the denominator (r^2 - r + 2) cannot be factored into linear factors
The expression is a rational function and can only be simplified by partial fraction decomposition which involves writing it as a sum of simpler fractional terms.
r (r³ -r+ 4/r) ÷ r(r - 1 + 2/r)
r³ -r+ 4/r ÷ r - 1 + 2/r
Hence, the simplified expression of (r⁴ - r² + 4) ÷ (r² - r + 2) is r³ -r+ 4/r ÷ r - 1 + 2/r
