Why is there an interest?You pay the interest on almost any loans and bank debt of money. The proportion of the loan balance used by lenders to compute interest. Clients who lend money can earn interest
We determine the monthly interest charge,
Interest charge = (1.5% per month) [tex]*[/tex] (5000 unpaid balance)
Interest charge [tex]= 75[/tex]
The new overdue debt is obtained by deducting the minimum monthly payment from the original unpaid balance:
Unpaid balance [tex]= 5000 - 125[/tex]
Unpaid balance [tex]= 4875[/tex]
we add the interest charge to the new unpaid balance to get the new balance:
New balance [tex]= 4875 + 75[/tex]
New balance [tex]= 4950[/tex]
Lastly, we may determine the purchasing power by deducting the new balance from the credit limit:
Purchasing power [tex]= 5000 - 4950[/tex]
Purchasing power [tex]= 50[/tex]
Therefore the unpaid balance on the credit card is [tex]4875[/tex], the new interest charge is [tex]75[/tex], and the purchasing power is [tex]50[/tex].

Find the indicated z score. The graph depicts the standard normal distribution with mean 0 and standard deviation 1. shaded area is 0.1949
The indicated z-score is 0.84.
What is the standard normal distribution?The standard normal distribution, also known as the Gaussian distribution or the bell curve, is a probability distribution that describes a set of data points that are normally distributed around the mean with a known variance. It is characterized by its mean, which is 0, and its standard deviation, which is 1. The shape of the distribution is symmetric and bell-shaped, with the highest probability density occurring at the mean.
From the given information, we know that the shaded area under the curve is 0.1949. This area corresponds to the probability that a random variable from a standard normal distribution falls between the mean and some unknown value, which we'll call "z".
Looking up the standard normal distribution table or using a calculator, we find that the z-score corresponding to an area of 0.1949 is approximately 0.84.
Therefore, the indicated z-score is 0.84.

18 people entered the race 2 people didn’t finish what is the ratio of those who finished the race to those that entered
The ratio of those who finished the race to those that entered will be 8:9.
What is ratio?
For evaluating the relationship between two numbers or quantities, we employ the ratio formula. The general manner of representing a ratio of between two quantities say 'a' and 'b' is a: b, which is interpreted as 'a is to b'.
A ratio describes how much of one quantity is necessary in relation to another. It is possible to combine and express the two terms in the ratio in their simplest form.
Given : total people entered = 18
people didn't finish = 2
So, people who finished = total people entered - people didn't finish
= 18 - 2
= 16
Hence, Ratio required = people who finished race / people who entered
= 16 / 18

Let a=4,b=4 and angle C=120 degrees. Find the length of side c and measure of the angles, angles A and B(in degrees). Give your answer to at least 3 decimal places.
c=
Angle A=
Angle B=
Step-by-step explanation:
law of cosine
c² = a² + b² - 2ab×cos(C)
c is the side opposite of the C angle. a and b are the other 2 sides.
AB² = 4² + 4² = 16 + 16 = 32
AB = c = sqrt(32) = 5.656854249...
since a and b are equal (isoceles triangle), so must be the angles at A and B.
the sum of all angles in a triangle is always 180°.
180 = angle A + angle B + angle C
= angle A + angle B + 120
since angle A = angle B we get
180 = 2×angle A + 120
2×angle A = 60°
angle A = angle B = 30°.

hailey invested $940 with an interest rate of 8.25 % that is compounded quarterly and Justin invested $940 with an interest rate of 7.625% that is compounded monthly
To the nearest dollar, how much money would Hailey have in her account when Justin's money has tripled in value?
To solve this problem, we need to first determine how long it will take for Justin's money to triple in value. We can use the formula for compound interest:
A = P(1 + r/n)^(nt)
where:
A = the final amount
P = the principal (initial amount)
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the number of years
For Justin, we have:
P = $940
r = 0.07625
n = 12 (monthly compounding)
t = unknown
We want to solve for t when A = 3P = $2820. We can rearrange the formula and plug in the values:
A = P(1 + r/n)^(nt)
3P = P(1 + r/n)^(nt)
3 = (1 + 0.07625/12)^(12t)
ln(3) = 12t * ln(1 + 0.07625/12)
t = ln(3) / (12 * ln(1 + 0.07625/12))
t ≈ 15.8 years
So it will take Justin about 15.8 years for his money to triple in value.
Now we can use the same formula to find how much money Hailey will have in her account after 15.8 years:
P = $940
r = 0.0825
n = 4 (quarterly compounding)
t = 15.8
A = P(1 + r/n)^(nt)
A = $940(1 + 0.0825/4)^(4*15.8)
A ≈ $3501
Therefore, Hailey will have about $3,501 in her account when Justin's money has tripled in value

(2) the height from which the ball is thrown
(3) the number of seconds it takes for the ball to reach the ground
(4) the number of seconds it takes for the ball to reach its maximum
height
The number 3 in the equation h(t) = -16t² + 6t+ 3 represents the initial height from which the ball is thrown.
The equation h(t) = -16t² + 6t+ 3 models the height of the ball thrown in the air, with h(t) measured in feet and time, t, measured in seconds. The number 3 in this equation refers to the height from which the ball is thrown. This is represented by the constant term 3, which is added to the equation after the sum of the variables. The formula h(t) = -16t² + 6t+ 3 can be broken down into three parts. The first part is the constant term, 3, which denotes the initial height of the ball. The second part is the linear term, 6t, which represents the acceleration of the ball due to gravity. Lastly, the quadratic term, -16t², is used to describe the rate at which the ball’s acceleration slows down due to air resistance. Therefore the number 3 in the equation h(t) = -16t² + 6t+ 3 represents the initial height from which the ball is thrown.

The area of the forest will be approximately 1396 km sq. after 10 years.
What will the area be after 10 years?Given that, a forest covers an area of 2100 km sq and that each year this area decreases by 4%..
Initial value = 2100rate = 4%Elapsed time = 10 yearsIf the area of the forest decreases by 4% each year, then after one year it will be 96% of the original size.
After two years, it will be 96% of 96% of the original size, or 0.96² of the original size.
After ten years, it will be 96% of itself ten times, or 0.96¹⁰ of the original size.
So the area of the forest after 10 years will be:
Area = Initial area × 0.96¹⁰
Area = 2100 km sq × 0.96¹⁰

Lim. Sin(1/theta)
Theta-0
Answer:
the limit of sin(1/θ) as θ approaches 0 is equal to 0.
Step-by-step explanation:
To evaluate this limit:
lim θ→0 sin(1/θ)
we can use the squeeze theorem. First, we note that -1 ≤ sin(1/θ) ≤ 1 for all values of θ, since the sine function oscillates between -1 and 1.
Next, we consider the limit of two other functions, -1/|θ| and 1/|θ|, as θ approaches 0:
lim θ→0 -1/|θ| = -∞
lim θ→0 1/|θ| = ∞
Since sin(1/θ) is always between -1/|θ| and 1/|θ|, we can apply the squeeze theorem to conclude that:
lim θ→0 sin(1/θ) = 0
Therefore, the limit of sin(1/θ) as θ approaches 0 is equal to 0.

The probability that a person who walked also sailed is 1/8.
Describe Probability?Probability is used to make predictions about the likelihood of future events, based on past observations or available information. It is widely used in fields such as statistics, finance, engineering, and science to analyze and model uncertain systems and processes.
Out of the 50 people, 3 did not participate in either walking or sailing. So, the number of people who participated in at least one activity is:
50 - 3 = 47
Out of these 47 people, 40 took part in walking and 18 took part in sailing. However, we need to subtract the number of people who participated in both activities because we don't want to count them twice. Let's call this number "x":
x = number of people who participated in both walking and sailing
So, the number of people who participated in at least one of the activities is:
40 + 18 - x
We know that there were 50 people in total, so we can write:
40 + 18 - x + 3 = 50
Simplifying this equation, we get:
55 - x = 50
x = 5
So, 5 people participated in both walking and sailing.
Now, we want to find the probability that a person who walked also sailed. Since there were 40 people who walked and 5 of them also sailed, the probability is:
5/40 = 1/8
Therefore, the probability that a person who walked also sailed is 1/8.

Bobbi owes a total of $10,455.75 in taxes.
What is taxes?Taxes are compulsory financial charges imposed by governments on individuals or entities based on income, property, or goods/services.
To compute the tax owed by Bobbi, we can use the following steps:
Calculate Bobbi's taxable income by subtracting the standard deduction and personal exemption from her total income:
Taxable income = $68,000 - $6,350 (standard deduction) - $4,050 (personal exemption) = $57,600
Determine the tax bracket in which Bobbi's taxable income falls:
Bobbi's taxable income of $57,600 falls in the 25% tax bracket.
Calculate the tax owed by Bobbi by applying the marginal tax rates to her taxable income. We can use the following formula:
Tax owed = (Taxable income - Previous tax bracket limit) x Marginal tax rate + Previous tax amount
In Bobbi's case, we need to calculate the tax owed in three steps, since her taxable income falls in the 10%, 15%, and 25% tax brackets:
For the first $9,325 of her taxable income, Bobbi owes 10% in taxes:
Tax owed = ($9,325 - $0) x 0.10 + $0 = $932.50
For the next $28,625 of her taxable income (up to $37,950), Bobbi owes 15% in taxes:
Tax owed = ($37,950 - $9,325) x 0.15 + $932.50 = $3,825.75
For the remaining $19,650 of her taxable income (up to $57,600), Bobbi owes 25% in taxes:
Tax owed = ($57,600 - $37,950) x 0.25 + $3,825.75 = $5,697.50

Which chart has an equation of y = 2.75x?
Answer:
None of it.
Step-by-step explanation:
Notice the slope is 2.75 this means for EVERY X the graph goes up by 2.75 in the Y axis. For example.
If at X=1 y=0
Then for X=2 y=2.75
and for X=3 y=2.75+2.75=5.5
also the graph must pass thought point (0,0), the origin, and none of the graph follow this.
You can also compare the slopes of each equations
for graph A, from x=1 to x=2 the height Y goes from 3 to 3.5, this is a slope of 0.5 (not the 2.75 we are looking for)
for graph A, from x=1 to x=2 the height Y goes from 1 to 2.5, this is a slope of 1.5 (not the 2.75 we are looking for)
for graph A, from x=1 to x=2 the height Y goes from 1 to 2.75 this is a slope of 1.75 (not the 2.75 we are looking for)
notice the last is similar to equation y=1.75X+b, just in case.
