Use the formula A=P\left(1+r/n)^nt to solve the compound interest problem.
Find how long it takes a 1700$ investment to earn 500$ interest if it is invested at 2% interest compounded quarterly.
500$ interest will be earned in approximately years. (Round to the nearest tenth.)
The total years taken to double the money according to Compounding will be 13.75 years.
What is compound interest?
Compound interest is that the interest on savings calculated on each the initial principal and therefore the accumulated interest from previous periods.
Main body:
Given :
rate = 2%
amount = $1700
Total amount = $2200
Compounded monthly,
so formula becomes,
Total amount = amount (1+r/400)^4t
T = A([tex](1+r/400)^{4t[/tex]
2200 = 1700(1 +2/400)^4t
22/17 = (1 +1/200)^4t
22/17 = (1.005)^4t
1.29 = (1.005)^4t
taking log on both sides
0.11/0.002 = 4t
t = 13.75 years.
Hence the time taken to double the money is 13.75 years.

Elizabeth is going to drive from her house to city a without stopping. Elizabeth’s house is 120 miles from Cytie and she plans to drive at a speed of 30 mph. Make a table of values and then write an equation for D in terms of t representing Elizabeth distance from city A t hours after leaving her house
A table of values that models this situation is as follows;
Distance (miles) Time (hour)
120 0
150 1
180 2
210 3
240 4
An equation for D in terms of t representing Elizabeth's distance from city A, t hours after leaving her house is d = 30t + 120.
How to write a function for the distance and time?Mathematically, a constant of proportionality (time) for Elizabeth's journey (distance) with respect to time can be represented with the following mathematical expression:
d = kt
Where:
d represents the distance.t represents the time.k represents the constant of proportionality (speed).Therefore, the required function that relates the distance (d) and speed (s) at t hours is given by;
d = 30t + 120
Next, we would develop a table of value;
At time (t) = 1 hour, we have;
Distance, d = 30(1) + 120
Distance, d = 150 miles.
At time (t) = 2 hours, we have;
Distance, d = 30(2) + 120
Distance, d = 180 miles.
At time (t) = 3 hours, we have;
Distance, d = 30(3) + 120
Distance, d = 210 miles.
At time (t) = 4 hours, we have;
Distance, d = 30(4) + 120
Distance, d = 240 miles.

2. The y coordinates for 3 are 10 and 6, and the x coordinates are 0 and 24.
10-6/0-24 is 4/-24 which is -1/6.
3. you do the same thing for #4. The y coordinates are 6 and 14, and the x coordinates are 0 and 20. 14-6/20-0=slope. 8/20 is the slope, and that is equal to 2/5.

Hakeem leans a 26-foot ladder against a wall so that it forms an angle of 72^{\circ} ∘ with the ground. What’s the horizontal distance between the base of the ladder and the wall? Round your answer to the nearest hundredth of a foot if necessary.
Answer:
To solve this problem, we can use the tangent function, which is defined as the ratio of the opposite side to the adjacent side of a right triangle. Since the angle formed by the ladder and the ground is 72 degrees, we can consider the horizontal distance between the base of the ladder and the wall to be the adjacent side of the right triangle, and the height of the ladder to be the opposite side.
We can set up the following equation to represent this relationship:
tan(72^{\circ}) = opposite/adjacent
Substituting the values given in the problem, we get:
tan(72^{\circ}) = 26 feet / adjacent
To find the value of the adjacent side, we can solve for "adjacent" in the equation above. We can do this by dividing both sides of the equation by 26 feet and then taking the inverse tangent (tan^(-1)) of both sides:
adjacent = 26 feet / tan(72^{\circ})
Using a calculator or a table of tangent values, we can find that the value of tan(72^{\circ}) is approximately 3.73. Substituting this value into the equation above, we get:
adjacent = 26 feet / 3.73
Solving this equation, we find that the horizontal distance between the base of the ladder and the wall is approximately 6.99 feet. Rounding this value to the nearest hundredth of a foot, we get an answer of approximately 6.99 feet.

For a total of 28seconds, a seagull flew east at 11meterspersecond. A sailor watched the seagull fly for one-quarter of that time. How far did the seagull fly while the sailor was watching?
Write your answer as a whole number.
meters
To find out how far the seagull flew while the sailor was watching, you can use the following steps:
Calculate the total distance the seagull flew in 28 seconds. You can do this by multiplying the seagull's speed (11 meters per second) by the time it flew (28 seconds):
Distance = Speed * Time
= 11 meters/second * 28 seconds
= 308 meters
Calculate the time the sailor watched the seagull fly. You can do this by dividing the total time the seagull flew (28 seconds) by 4:
Time = 28 seconds / 4
= 7 seconds
Calculate the distance the seagull flew while the sailor was watching. You can do this by multiplying the seagull's speed (11 meters per second) by the time the sailor watched the seagull fly (7 seconds):
Distance = Speed * Time
= 11 meters/second * 7 seconds
= 77 meters
Therefore, the seagull flew 77 meters while the sailor was watching.

If you make this wager vary many times, what will be the mean amount you win?
The mean amount won based on the expectation formula of probability will be - 2/13.
What is probability?The probability of an event occurring is defined by probability.
Probability is also called chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.
Probability of winning = 4/52 = 1/13
Probability of lossing = 1 - 1/13 = 12/13
The mean amount or expectation is given as,
E(X) = 10 × (1/13) + - 1(12/13)
E(X) = 10/13 - 12/13

The number of ways the books could be arranged on the shelves is calculated using the following permutation formula
Total = ⁿPᵣ
Where
n = 6 and r = 4
Substitute the known values in the above equation, so, we have the following representation
Total = ⁶P₄
Apply the permutation formula
ⁿPᵣ = n!/(n - r)!
So, we have the following representation
Total = 6!/2!
Evaluate the quotient
Total = 360
Hence, the number of ways is 360

In how many different ways can we distribute 5 different books among 10 children if any child can get any number of books?
Using the formula of combination and the provided condition that any child can get any number of books, The answer is 637.
What is combination?Combinations are mathematical operations that count the number of potential configurations for a set of elements when the order of the selection is irrelevant. We use permutation to determine how many possible ways we have to arrange items from a collection system.
What is the formula of combination?The required formula is:
[tex]C(n,r) = \frac{n!}{r!(n-r)!}[/tex]
where, n= total number of objects in the set.
r= number of choosing objects from the set.
from the given data, total number of books = n= 5
number of children we need to distribute, r= 10
total possible ways of distribution= C(10,1)+C(10,2)+C(10,3)+C(10,4)+C(10,5)
=10+45+120+210+252
=637
hence, we have total 637 possible ways to distribute.

. The length of a rectangle is represented by 4x and the width by 2x + 1 Determine the perimeter of the rectangle as a simplified expression in standard form. (hint: perimeter=2w+21)
The perimeter of the rectangle can be expressed as 12x+2
What is perimeter of a rectangle?The perimeter of a rectangle is the total distance covered by its boundaries or the sides. Since there are four sides of a rectangle, thus, the perimeter of the rectangle will be the sum of all four sides.
The perimeter of a rectangle is given as 2(l+w)
where l is the length and w is the width.
If the length is represented by 4x and width by 2x+1, therefore the perimeter of the rectangle = 2(4x+2x+1)
= 2( 6x+1)
= 12x+2
the perimeter can also be found by adding all the four sides, this means that
perimeter = 4x+4x+2x+1+2x+1=8x+4x+2= 12x+2
therefore the perimeter of the rectangle is 12x+2.
