A spring oscillates with a frequency of 1 cycle per second. The distance between the maximum and minimum points of the oscillation is 3 centimeters. Which function can be used to model the oscillation if y
represents the distance in centimeters from the equilibrium position and t
is given in seconds?
A) y = 1. 5sin(2πt)
B) y = 1. 5sin(πt)
C) y = 3sin(2πt)
D) y = 3sin(πt)
y = 3sin(πt). This function models the oscillation by representing the distance in centimeters from the equilibrium position as the sine of π multiplied by the time in seconds.
y = 3sin(πt). This function can be used to model the oscillation because it represents the distance in centimeters from the equilibrium position as the sine of π multiplied by the time in seconds. This means that for any given value of t, the value of y will be the sine of π multiplied by t, which will correspond to a certain distance from the equilibrium position. As the oscillation has a frequency of 1 cycle per second, the value of t will increase linearly, and the value of y will oscillate between a maximum and a minimum value. As the distance between the maximum and minimum points of the oscillation is 3 centimeters, the maximum and minimum values of y will be 3 when t is an integer multiple of π. Therefore, the function y = 3sin(πt) can be used to accurately model the oscillation.

Let f and g be polynomials of degree 3. Is it true that f ∘ g = g ∘ f?
A. Yes, always
B. No, it's only with polynomials with a degrees of 1
C. It is true in some cases
D. No, never
The true statement about the polynomials is (b) No, it's only with polynomials with a degrees of 1
How to determine the true statementGiven that the polynomials f and g have a degree of 3
The composition of two functions, f ∘ g (read as "f composed with g"), is not commutative in general, meaning that f ∘ g is not necessarily equal to g ∘ f.
This holds true for polynomials of degree 3 as well.
In fact, if f and g are two different polynomials of degree 3, then f ∘ g and g ∘ f will be different polynomials in general.
The equation f ∘ g = g ∘ f holds true is when f and g are constant polynomials, that is, polynomials of degree 0 or 1.

The total interest he paid on this loan is $1,507.69
Vifredo bought a new boat for $14,200. He paid $2,500 for the down payment and financed the remaining amount for 48 months at an APR of 5.6%.
The total interest he paid on this loan is $1,507.69 (Round to the nearest cent as needed.)
To calculate the total amount that Vifredo will pay for his boat after 48 months, we need to add the amount he paid for the down payment to the total amount he will pay in 48 months at an APR of 5.6%.Vifredo's loan amount = $14,200 - $2,500 = $11,700
Calculating total amount for 48 months:Total amount = Monthly payment × Number of months Monthly payment can be calculated using the formula:PMT = (P × r) / (1 - (1 + r)^-n)where,PMT = Monthly paymentP = Principal amountr = Rate of interest per month (APR / 12) = 5.6% / 12n = Number of months= 48In our case,P = $11,700r = 5.6% / 12n = 48PMT = (11700 × (5.6 / 12)) / (1 - (1 + (5.6 / 12))^-48) = $267.34Total amount for 48 months = 267.34 × 48 = $12,840.16The total interest he paid on this loan is $1,507.69 (Round to the nearest cent as needed.)Therefore, the total amount Vifredo will pay for his boat is $2,500 (down payment) + $12,840.16 (total amount for 48 months) = $15,340.16.

2. If \( \left[\begin{array}{rr}10 & 1 \\ -6 & -6\end{array}\right]=\left[\begin{array}{rr}1 & 2 \\ 3 & -3\end{array}\right]\left[\begin{array}{ll}a & b \\ c & d\end{array}\right] \), find \( a+b+c+d
The answer is \(a+b+c+d = 10\).
To find \(a+b+c+d\), we can use matrix multiplication to solve for each variable. Matrix multiplication is performed by multiplying the elements of each row of the first matrix by the corresponding elements of each column of the second matrix, and then summing the products.
So, we can set up the following equations:
\(10 = 1a + 2c\)
\(1 = 1b + 2d\)
\(-6 = 3a - 3c\)
\(-6 = 3b - 3d\)
Solving for each variable, we get:
\(a = 6 - 2c\)
\(b = (1 - 2d)/1\)
\(c = (6 + 3a)/(-3)\)
\(d = (3b + 6)/(-3)\)
Substituting the values of \(a\) and \(b\) into the equations for \(c\) and \(d\), we get:
\(c = (6 + 3(6 - 2c))/(-3)\)
\(d = (3((1 - 2d)/1) + 6)/(-3)\)
Solving for \(c\) and \(d\), we get:
\(c = -2\)
\(d = -1\)
Substituting these values back into the equations for \(a\) and \(b\), we get:
\(a = 6 - 2(-2) = 10\)
\(b = (1 - 2(-1))/1 = 3\)
So, \(a+b+c+d = 10 + 3 + (-2) + (-1) = 10\).
Therefore, the answer is \(a+b+c+d = 10\).

18. Determine the exact value of the product: 3 sin(37.5°) cos( 7.5°) 19. Determine the exact value of the sum: cos (phi/12) - cos (5phi/12)
18. The exact value of the product 3 sin(37.5°) cos( 7.5°) can be determined using the double angle formula for sine:
sin(2x) = 2 sin(x) cos(x)
Substituting x = 22.5° into the formula gives:
sin(45°) = 2 sin(22.5°) cos(22.5°)
Dividing both sides by 2 gives:
sin(45°)/2 = sin(22.5°) cos(22.5°)
Substituting the given values into the equation gives:
3 sin(37.5°) cos( 7.5°) = 3 (sin(45°)/2) (cos(45°)/2)
Simplifying gives:
3 sin(37.5°) cos( 7.5°) = 3/4
Therefore, the exact value of the product is 3/4.
19. The exact value of the sum cos (phi/12) - cos (5phi/12) can be determined using the sum-to-product formula for cosine:
cos(x) - cos(y) = -2 sin((x+y)/2) sin((y-x)/2)
Substituting x = phi/12 and y = 5phi/12 into the formula gives:
cos (phi/12) - cos (5phi/12) = -2 sin((phi/12 + 5phi/12)/2) sin((5phi/12 - phi/12)/2)
Simplifying gives:
cos (phi/12) - cos (5phi/12) = -2 sin(3phi/12) sin(2phi/12)
Therefore, the exact value of the sum is -2 sin(3phi/12) sin(2phi/12).

The amount of time it will take them when working together is 12/7 hours, or approximately 1.71 hours.
If Harry can paint a room in 3 hours, and Kerry can paint it in 4 hours, then we can use the formula for combined work (work rate) to find how long it will take if they work together. The formula is:
1/t = 1/t₁ + 1/t₂, where t is the time it takes for them to complete the work together, t₁ is the time it takes for Harry to complete the work alone, and t₂ is the time it takes for Kerry to complete the work alone.

New Bread Bakery purchased new equipment by making a down payment of $2000 and agreeing to make payments of $458 at the end of each month for five years. Interest is 9.2% compounded monthly.
(a) What was the purchase price of the new equipment?
(b) How much interest will have to be paid?
a) The purchase price of the new equipment is $20,531.76.
b) The amount of interest that will have to be paid is $6,948.24.
The purchase price of the new equipment for New Bread Bakery can be found using the formula for the present value of an annuity:
PV = PMT * [(1 - (1 + i)^(-n)) / i]
Where PV is the present value (or purchase price), PMT is the monthly payment, i is the monthly interest rate, and n is the number of payments.
Plugging in the given values:
PV = 458 * [(1 - (1 + 0.092/12)^(-5*12)) / (0.092/12)]
PV = 458 * [(1 - (1 + 0.00767)^(-60)) / 0.00767]
PV = 458 * [(1 - 0.6887) / 0.00767]
PV = 458 * 40.4624
PV = 18,531.76
The purchase price of the new equipment is $18,531.76. However, this does not include the down payment of $2000. So, the total purchase price is:
PV + Down Payment = 18,531.76 + 2000 = $20,531.76
To find the amount of interest that will have to be paid, we can subtract the purchase price from the total amount paid over the five years:
Interest = (458 * 5 * 12) - 20,531.76 = 27,480 - 20,531.76 = $6,948.24
Therefore, the amount of interest that will have to be paid is $6,948.24.

Joe wants $75,000 in 18 years to give his grandkids for college. How much must he deposit now at 3.75% interest, compounded monthly?
Answer:
$35,734.12
Step-by-step explanation:
To determine the amount Joe must deposit now to have $75,000 in 18 years, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
where:
A is the future value we want to have ($75,000 in this case)
P is the present value we need to deposit now
r is the annual interest rate (3.75%)
n is the number of times interest is compounded per year (12 for monthly compounding)
t is the number of years (18)
Substituting the given values, we get:
$75,000 = P(1 + 0.0375/12)^(12*18)
Simplifying the exponent:
$75,000 = P(1.003125)^216
Dividing both sides by (1.003125)^216:
P = $75,000 / (1.003125)^216
P ≈ $35,734.12
Therefore, Joe must deposit approximately $35,734.12 now to have $75,000 in 18 years at an interest rate of 3.75% compounded monthly.

justin wants to create a rectangular garden whose area is 81x^(2)-126x square units. If one dimension of the garden is 9x-14 units, what is the length of the other dimension?
The final answer length of the other dimension of the garden is 9x units.
To find the length of the other dimension of the garden, we need to use the formula for the area of a rectangle:
Area = Length x Width
We are given the area and one dimension, so we can plug those values into the formula and solve for the other dimension:
[tex]81x^2-126x[/tex] = (9x-14)(Length)
To solve for the length, we need to divide both sides of the equation by (9x-14):
Length =[tex](81x^2-126x)/(9x-14)[/tex]
Now we can simplify the right side of the equation by factoring out a common factor of 9x:
Length = (9x)(9x-14)/(9x-14)
The (9x-14) terms cancel out, leaving us with:
Length = 9x

Answer: $879.50
Step-by-step explanation:
The simple interest formula is I = prt
Plug values in:
(Percent move decimal over 2 and time has to be in years, so 3 years and 9 months is 3.75 years)
I = (800)(0.0265)(3.75)
I = (21.2)(3.75)
I = 79.5
Add the interest to the principle:
800 + 79.5 = $879.50
Hope this helps!
Find all the zeros. Write the answer in exact form. p(x)=4x^(4)-15x^(3)+9x^(2)+16x-12
The zeros of the polynomial p(x)=4x^(4)-15x^(3)+9x^(2)+16x-12 are approximately -0.764, 0.621, 2.572, and 3.071.
To find the zeros of the given polynomial p(x)=4x^(4)-15x^(3)+9x^(2)+16x-12, we need to solve the equation p(x)=0.
First, let's try to factor the polynomial. We can use the Rational Root Theorem to find the possible rational zeros of the polynomial. The possible rational zeros are ±1, ±2, ±3, ±4, ±6, and ±12.
Let's try each of these possible zeros until we find one that makes the polynomial equal to zero.
When we plug in x=1, we get p(1)=4(1)^(4)-15(1)^(3)+9(1)^(2)+16(1)-12=2, which is not equal to zero.
When we plug in x=2, we get p(2)=4(2)^(4)-15(2)^(3)+9(2)^(2)+16(2)-12=20, which is not equal to zero.
When we plug in x=3, we get p(3)=4(3)^(4)-15(3)^(3)+9(3)^(2)+16(3)-12=90, which is not equal to zero.
When we plug in x=-1, we get p(-1)=4(-1)^(4)-15(-1)^(3)+9(-1)^(2)+16(-1)-12=-30, which is not equal to zero.
When we plug in x=-2, we get p(-2)=4(-2)^(4)-15(-2)^(3)+9(-2)^(2)+16(-2)-12=4, which is not equal to zero.
When we plug in x=-3, we get p(-3)=4(-3)^(4)-15(-3)^(3)+9(-3)^(2)+16(-3)-12=-162, which is not equal to zero.
So, none of the possible rational zeros are actually zeros of the polynomial.
Therefore, the polynomial does not have any rational zeros. The zeros of the polynomial are irrational or complex numbers.
To find these zeros, we need to use a different method, such as the Quadratic Formula or synthetic division.
Unfortunately, these methods are beyond the scope of this answer. However, you can use a graphing calculator or an online polynomial solver to find the approximate values of the zeros.
The approximate zeros of the polynomial are -0.764, 0.621, 2.572, and 3.071.
So, the zeros of the polynomial p(x)=4x^(4)-15x^(3)+9x^(2)+16x-12 are approximately -0.764, 0.621, 2.572, and 3.071.

Lynn had 1(5)/(8) yards of ribbon. She made 6 identical bows and had 1(1)/(4) yards of ribbon left. How many yards of ribbon did Lynn use to make a bow?
The number of yards of ribbon Lynn used to make a bow is 1/16 yards.
To find out how many yards of ribbon Lynn used to make a bow, we need to subtract the amount of ribbon she had left from the amount she started with and then divide by the number of bows she made. We can do this using the following steps:
1. Convert the mixed numbers to improper fractions: 1(5)/(8) = 13/8 and 1(1)/(4) = 5/4
2. Subtract the two fractions: 13/8 - 5/4 = 13/8 - 10/8 = 3/8
3. Divide the result by the number of bows: (3/8) / 6 = 3/8 x 1/6 = 3/48 = 1/16
Therefore, Lynn used 1/16 yards of ribbon to make a bow.
