You would like to give your daughter $50,000 towards her college education 15 years from now. How much money must you set aside today for this purpose if you can earn 9 percent on your investments?
To give your daughter $50,000 towards her college education in 15 years, you must set aside approximately $14,803.42 today.
To calculate the amount of money you need to set aside today, we can use the concept of future value of a lump sum. The future value is the amount of money an investment will grow to in the future, given a certain interest rate and time period.
In this case, we want to determine the present value (the amount you need to set aside today) to achieve a future value of $50,000 in 15 years, assuming an annual interest rate of 9 percent. The formula to calculate present value is:
Present Value = \(Future Value / (1 + Interest Rate)^T^i^m^e\)
Plugging in the values, we have:
Present Value = \($50,000 / (1 + 0.09)^1^5\)
Present Value ≈ $14,803.42
Therefore, you would need to set aside approximately $14,803.42 today in order to accumulate $50,000 for your daughter's college education in 15 years, assuming an annual interest rate of 9 percent.

evaluate sin 315 without a calculator
Answer:
-0.7071.
Step-by-step explanation:
The value of function sin 315 is -1/2.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Sin 315 degrees can be found by using the unit circle.
The unit circle is a circle with the radius of one centered at the origin of a coordinate plane.
Every point on the unit circle is a point that is one unit away from the origin.
The unit circle is used to help find the exact values of the trigonometric functions at specific angles.
The angle 315 degrees is in the fourth quadrant of the unit circle, so the x-coordinate is negative and the y-coordinate is negative.
Using the x-coordinate, we can calculate the sine to be -1/2.
Hence, the value of function sin 315 is -1/2.

Using a linear function, it is found that the maximum number of miles you can drive during a 1-day rental is of 790.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, we have that:
The intercept is 26.2.The slope is 0.22.Hence the function for the cost of driving x miles is:
y = 26.2 + 0.22x.
He can spend at most 200, hence:
0.22x + 26.2 = 200
0.22x = (200 - 26.2)
x = (200 - 26.2)/0.22
x = 790.

Combining negatively correlated assets having the same expected return results in a portfolio with ____ level of expected return and ____ level of risk. Select one: a. a higher; a lower b. the same; a lower c. the same; a higher d. a lower; a higher
Combining negatively correlated assets with the same expected return results in a portfolio with the same level of expected return but a lower level of risk.
When assets have a negative correlation, their returns tend to move in opposite directions. By combining these assets in a portfolio, their negative correlation offsets each other's risks to some extent. As a result, the overall risk of the portfolio is reduced.
However, the expected return of the portfolio remains the same as the individual assets, assuming they have the same expected return. This is because the negative correlation does not affect the average return of the assets, only their volatility. The diversification benefits provided by negatively correlated assets help to reduce the overall risk of the portfolio, making it less volatile than the individual assets.
Therefore, combining negatively correlated assets with the same expected return results in a portfolio with the same level of expected return but a lower level of risk. This is a desirable outcome for investors as it allows them to achieve a certain level of return while minimizing the overall risk in their investment portfolio.

at travis' birthday party, `\frac{3}{4}` of his birthday cake was eaten. the next day, travis ate `\frac{1}{3}` of the remaining cake. what fraction of the whole cake did travis eat the next day
Travis ate 1/12 of the whole cake the next day
A fraction represents a part of a whole. In this case, the whole cake represents the whole, and the part that was eaten represents the fraction. When we say that 3/4 of the cake was eaten, it means that out of the whole cake, 3/4 or three-fourths of the cake was consumed.
Travis ate 1/3 of the remaining cake the next day.
This means that after 3/4 of the cake was eaten, there was 1/4 of the cake remaining. Travis ate 1/3 of that remaining 1/4 of the cake, which can be written as
=> 1/3 x 1/4.
To simplify this fraction, we multiply the numerators (1 x 1) and the denominators (3 x 4), giving us 1/12.
We can write this fraction as a percentage, which is 8.33%. To summarize, fractions are used to represent parts of a whole, and in this case, Travis ate 1/12 or 8.33% of the whole cake the next day.

You decide to travel by car for your holiday visits this year. You leave early in the morning to avoid congestion on the roads. This enables you to drive at a comfortable speed of v1=65.6mph for t1=2.08 hours. However, after this time, you unexpectedly come to a stop for tsop =33.6 min. Traffic starts moving again and you finish your travel at v2=57.2mph for an additional t2=1.25 hours. There are 1609 meters in one mile. What was the total distance d traveled? d= Incorrect What was the average speed vˉ?
The total distance traveled is approximately 207.948 miles and the average speed is approximately 53.48 mph.
To find the total distance traveled, we need to calculate the distance traveled during each segment of the journey and then sum them up.
Distance traveled during the first segment:
```
d1 = v1 * t1
= 65.6 mph * 2.08 hours
```
Distance traveled during the stop:
Since the car comes to a stop, the distance traveled during this time is zero.
Distance traveled during the second segment:
```
d2 = v2 * t2
= 57.2 mph * 1.25 hours
```
Now we can calculate the total distance traveled:
```
d = d1 + d2
```
Let's calculate the values:
```
d1 = 65.6 mph * 2.08 hours = 136.448 miles
d2 = 57.2 mph * 1.25 hours = 71.5 miles
d = d1 + d2 = 136.448 miles + 71.5 miles = 207.948 miles
tstop = 33.6 min = 33.6/60 hours = 0.56 hours
= 207.948 miles / (2.08 hours + 0.56 hours + 1.25 hours) = 207.948 miles / 3.89 hours ≈ 53.48 mph
```
Therefore, the total distance traveled is approximately 207.948 miles and the average speed is approximately 53.48 mph.

which is an iterative method that can find roots of a polynomial equation given an initial approximation.
According to the fundamental theorem of algebra, how many zeros does the function f(x) = 17x^15 + 41x^12 + 13x^3 − 10 have?The fundamental theorem of algebra states that every polynomial function has at least one zero or root. A polynomial function of degree n can have at most n roots or zeros, so the answer to this question will be less than or equal to the degree of the polynomial. Here, f(x) is a polynomial of degree 15. Therefore, f(x) can have at most 15 zeros or roots.We cannot use the Rational Zeroes Theorem, because the coefficients of f(x) are not integers. However, we can use technology (like a graphing calculator) or numerical methods to approximate the roots.
The number of zeros the function has, however, cannot be determined without approximation.The correct answer is:long answer:According to the fundamental theorem of algebra, every polynomial equation of degree n (where n is a non-negative integer) has exactly n roots. In other words, the polynomial equation f(x) = 17x^15 + 41x^12 + 13x^3 − 10 has exactly 15 roots, counting multiplicity.Since the polynomial f(x) has no rational roots (i.e., roots that can be expressed as a fraction of integers), it cannot be factored using integer coefficients. This makes it difficult to determine the roots of the polynomial analytically.
However, we can use numerical methods or technology to approximate the roots of the polynomial. One such method is to use the Newton-Raphson method, which is an iterative method that can find roots of a polynomial equation given an initial approximation.

Mr. avola is deciding which of these packages of cheese to buy (package 1: SLICED cheese 12oz for 3 dollars) (package 2: BLOCK of cheese 1.5lbs for 5.52 dollars) which package cost less per ounce?
Answer:
Package 2
Step-by-step explanation:
Mr. avola is deciding which of these packages of cheese to buy
For Package 1
Package 1: SLICED cheese 12oz for 3 dollars
12oz = 3 dollars
1 oz = x
Cross Multiply
12 oz × x = 3 × 1 oz
x = 3 × 1 oz/12 oz
x = 0.25 dollars
Hence, Package 1 cost 0.25 dollars per ounce
For Package 2
Package 2: BLOCK of cheese 1.5lbs for 5.52 dollars.
We convert Ibs to oz
1 Ibs = 16 oz
1.5 Ibs = x
x = 1.5Ibs × 16 oz/1 Ibs
x = 24 oz
Hence:
24oz = 5.52 dollars
1 oz = x
Cross Multiply
24 oz × x = 5.52 × 1 oz
x = 5.52 × 1 oz/24oz
x = 0.23 dollars
Package 2 cost 0.23 dollars per ounce
Therefore, the package that cost less per ounce is Package 2
For Exercises 30-33, find the speed for the given motion of a particle. Find any times when the particle comes to a stop. 32. x cos 2t , ysin t
We found the speed of the particle as √(4096sin²(2t) + y²cos²(t)), where t is the time and we identified the times when the particle comes to a stop as t = π/2, 3π/2, 5π/2, ...
To calculate the speed of the particle, we first need to find its velocity vectors. The velocity vector of a particle is the derivative of its position vector with respect to time.
Given:
x = 32cos(2t) (Equation 1)
y = ysin(t) (Equation 2)
Differentiating Equation 1 with respect to time (t):
dx/dt = -64sin(2t) (Equation 3)
Differentiating Equation 2 with respect to time (t):
dy/dt = ycos(t) (Equation 4)
So, the velocity vector v(t) = (dx/dt)i + (dy/dt)j is given by:
v(t) = -64sin(2t)i + ycos(t)j
Step 2: Speed of the particle
The speed of the particle at any given time t is the magnitude of its velocity vector. Let's calculate the speed using the formula:
Speed (|v(t)|) = sqrt((dx/dt)² + (dy/dt)²)
Substituting the values from Equations 3 and 4 into the speed formula, we get:
Speed (|v(t)|) = sqrt((-64sin(2t))² + (ycos(t))²)
Simplifying further:
Speed (|v(t)|) = sqrt(4096sin²(2t) + y²cos²(t))
Step 3: Finding when the particle comes to a stop
To determine when the particle comes to a stop, we need to find the values of t for which the speed of the particle is zero. In other words, we need to solve the equation:
Speed (|v(t)|) = 0
From the equation derived in Step 2, we can see that the speed will be zero only if both terms inside the square root are zero simultaneously. This leads us to two cases:
Case 1: sin²(2t) = 0
For this case, we solve sin(2t) = 0, which gives us t = 0, π/2, π, 3π/2, 2π, ...
Case 2: y²cos²(t) = 0
For this case, we solve ycos(t) = 0. Since y is a constant and cannot be zero (as it is not given), we conclude that cos(t) = 0. This gives us t = π/2, 3π/2, 5π/2, ...
By combining the solutions from both cases, we find that the particle comes to a stop at t = π/2, 3π/2, 5π/2, ...

The slope of the line joining the points (-2, 6) and (4, 8) is 1/3.
In the given question, we have to find the slope of the line joining the points (-2, 6) and (4, 8).
The point-slope approach is typically used when two points that sit on a specific line are specified.
A line's equation is written as y - y(1) = m(x - x(1)), where y(1) is the Y-axis coordinate, m is the slope, and x(1) is the X-axis coordinate.
Firstly we find the value of m using the formula
m = \(\frac{y(2)-y(1)}{x(2)-x(1)}\)
From the given points x(1) = -2, y(1) = 6, x(2) = 4, y(2) = 8.
