Claudia deposited $1,000 today. Assuming 7% annual interest, how much will the $1,000 be worth in one year?
Steven White plans to retire in 15 years with $400,000 saved. He thinks his savings can earn 10 percent per year. How much does Steven White have to deposit today in order to have $400,000 in 15 years?
What will a deposit of $4,500 today at 10% compounded semiannually be worth if left in the bank for six years?
If Joe deposits every payment in an account paying a nominal annual interest rate of 6% compounded monthly, how much will he have at the end of three years?
If you want $1,000 five years from now and you earn 5 percent on your savings, how much do you need to deposit today?
The distinction between present value and future value is that the former is required now and the latter is needed at a future period
What is the difference between present value and future value?
The present value indicates today's worth or dollars of a future value of a flow whereas the future value determines the future worth of an investment or deposit made today or deposits over a number of years at a time in the future
The amount that Claudia would have in a year's time is future value because the present value is the initial deposit made today
The amount that Steven would have to deposit today in order to accumulate $400,000 in 15 years is the present value
The amount that a deposit of $4,500 made today would worth in 6 years is the future value because the initial deposit is the present value.
Joe would have to deposit payments in expectation of future value after 3 years and the deposit required today to earn a rate of return of 5% in order to have $1000 in 5 years is a present value

The equation of the line is
Answer:
y = -x +3
Step-by-step explanation:
You want the slope-intercept equation of the line with the same intercept as -3y = -9 +3x, and the same slope as -2x -2y = -8.
Slope-intercept formThe slope-intercept form of the equation of a line is ...
y = mx +b . . . . . where m is the slope, and b is the y-intercept
For the given equations, we can put them in this form to find the desired parameters.
-3y = -9 +3x
y = -x +3 . . . . . . . . . . divide both sides by -3
We observe that the y-intercept is +3, which we will need for our answer.
The slope-intercept form of the second equation is ...
-2x -2y = -8
x + y = 4 . . . . . . . . . . divide by -2
y = -x +4 . . . . . . . . . . subtract x
We observe that the slope (coefficient of x) is -1, which we will need for our answer.
Desired equationWe want the equation of the line with slope -1 and y-intercept 3. It is ...
y = -x +3 . . . . . . . . . . same as the equation of the first line
__
Additional comment
The slope-intercept equation (green) is plotted using dots, so that you can see it is coincident with the line described by the first equation (red). Parallel lines have the same slope, so our desired line must be parallel to the blue line. (It is.)

Anna invested $69,000 in an account paying an interest rate of % compounded 8 1/2 % continuously. Hudson invested $69,000 in an account paying an interest rate of 8 3/8 % compounded daily. After 10 years, how much more money would Anna have in her account than Hudson, to the nearest dollar?
The solution of compound interest problem using formula of amount is
Anna have$2,734 more money than Hudson.
what is compound interest ?Compound interest is a type of interest in which the interest gained is added to the principal sum before the interest for the subsequent period is calculated using the updated total sum. In other words, in addition to the initial principal, the accumulated interest from prior periods is also taken into account for calculating interest. As a result, as time passes, the interest earned increases, increasing the total amount earned or due. Savings accounts, loans, and investments frequently use compound interest.
According to given informationFor continuous compounding, the formula is:
A = Pe^(rt)
Where:
A = the amount after t years
P = the principal amount
r = the annual interest rate (as a decimal)
t = the time in years
For daily compounding, the formula is:
A = P(1 + r/n)^(nt)
Where:
A = the amount after t years
P = the principal amount
r = the annual interest rate (as a decimal)
n = the number of times compounded per year
t = the time in years
Using these formulas, we can calculate the amount that Anna and Hudson will have after 10 years, and then find the difference between them.
For Anna's investment:
r = 8.5% = 0.085 (as a decimal)
t = 10 years
P = $69,000
A = Pe^(rt) = 69000 * e^(0.085*10) = $156,794.63
For Hudson's investment:
r = 8 3/8% = 8.375% = 0.08375 (as a decimal)
n = 365 (daily compounding)
t = 10 years
P = $69,000
A = P(1 + r/n)^(nt) = 69000(1 + 0.08375/365)^(365*10) = $154,060.52
Therefore, the difference between the two amounts is:
$156,794.63 - $154,060.52 = $2,734.11
So Anna will have approximately $2,734 more in her account than Hudson after 10 years.

Samir and Kylie are making fruit salads for a picnic. Samir mixes 1 cup of melon and 3 cups of apple and Kylie mixes 2 cups of melon and 9 cups of apple. Use Samir and Kylie’s percent of melon to determine whose fruit salad will taste more melony.
Answer:
Step-by-step explanation:
Samir total cups = 1 + 3 = 4
% melon = 1/4 x 100 = 25%
Kylie total cups = 2 + 9 = 11
% melon = 2/11 x 100 = 18%
Samir's is more melony. 25% > 18%
a formula in the form y=mx+b models the cost, y, of four-year college x years after 2010. would you expect m to be positive, negative, or zero? explai your answer
we would expect m to be positive.
In this case, we're considering a formula of the form y = mx + b, where y represents the cost of a four-year college x years after 2010. The variable m represents the coefficient of x, which determines the slope of the line.
Since we're discussing the cost of college, it's reasonable to expect that it generally increases over time. Therefore, we would expect the coefficient m to be positive. A positive value of m indicates that as the number of years after 2010 increases (x), the cost of college (y) will also increase.
If m were negative, it would imply a decreasing cost over time, which is less likely for a four-year college. If m were zero, it would indicate that the cost remains constant regardless of the number of years after 2010, which is also unlikely given the rising trend in college costs.

Solve for θ if −10sinθ−8=5√3−8 and 0≤θ<2π.
The value of variable θ would be,
⇒ θ = 5π/3 and θ = 4π/3
We have to given that;
Expression is,
⇒ - 10sin θ - 8 = 5√3 - 8
Now, We can simplify as;
⇒ - 10sin θ - 8 = 5√3 - 8
⇒ - 10sin θ = 5√3
⇒ sin θ = - 5√3/10
⇒ sin θ = - √3/2
We know that sinθ = -√3/2 when θ = 4π/3 and θ = 5π/3 (among other angles).
However, since 0 ≤ θ < 2π, only the angles in the second and third quadrants are valid solutions for sinθ = -√3/2.
Therefore, the solutions are θ = 5π/3 and θ = 4π/3, option D is correct.

The summer has ended and it’s time to drain the swimming pool. 20 minutes after pulling the plug, there is still 45 000L of water in the pool. The pool is empty after 70 minutes.
Calculate the rate that the water is draining out of the pool.
b) Calculate how much water was in the pool initially.
c) Write an equation for this relationship.
d) Use your equation to calculate how much water is in the pool at
62 minutes.
Answer:
a) -900 L/min
b) 63000 L
c) v = -900t +63000
d) 7200 L
Step-by-step explanation:
a) You are given two points on the curve of volume vs. time:
(t, v) = (20, 45000) and (70, 0)
The rate of change is ...
Δv/Δt = (0 -45000)/(70 -20) = -45000/50 = -900 . . . . liters per minute
__
b) In the first 20 minutes, the change in volume was ...
(20 min)(-900 L/min) = -18000 L
So, the initial volume was ...
initial volume -18000 = 45000
initial volume = 63,000 . . . . liters
__
c) Since we have the slope and the intercept, we can write the equation in slope-intercept form:
v = -900t +63000
__
d) Put the number in the equation and do the arithmetic.
When t=62, the amount remaining is ...
v = -900(62) +63000 = -55800 +63000 = 7200
7200 L remain after 62 minutes.

How to find the side of a triangle?A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees. The side y of the triangle can be found using sine law.
Therefore,
a / sin A = b / sin B = c / sin C
Applying the sine law,
y / sin 106 = 15 / sin 51
cross multiply
y sin 51° = 15 sin 106°
divide both sides by sin 51°
y sin 51° / sin 51° = 15 sin 106° / sin 51°
y = 15 sin 106° / sin 51°
Therefore,
y = 15 × 0.96126169593 / 0.77714596145
y = 14.4189254391 / 0.77714596145
