The compound interest after 7 years is $2701.
What is compound interest?
The interest on savings that is computed on both the initial principal and the interest accrued over time is known as compound interest. Compound interest is computed by multiplying the starting principal amount by one and the annual interest rate raised to the number of compound periods minus one. The final step is to deduct the initial loan principal from the calculated value.
When the amount compounds quarterly, it means that the amount compounds 4 times in a year. i.e., n = 4. We use this fact to derive the quarterly compound interest formula. Thus, the quarterly compound interest formula is:
A = P (1 + r/12)[tex].^{n/12}[/tex]
A = 2100(1+3.6/12)[tex].^{7/12}[/tex]
A=2701
Hence the compound interest after 7 years will be $2701.

A scuba diver descends in the water at a rate of 23.5 feet per minute for 2.6 minutes. He immediately changes course when he sees a large fish and ascends at a rate of 28 feet per minute for 2 minutes. What is the scuba diver's position relative to sea level after the 4.6 minutes? Enter your answer as a decimal in the box.
Answer:
Step-by-step explanation:
t is given that a scuba driver descends in water for 2.8 minutes at a rate of feet per minute.
Let's assume the descending position as negative.
The position at which the scuba driver will be after 2.8 minutes is :
= - feet per minute × 2.8 minutes
= - 57.4 feet
Now , he sees a large fish and changes his direction and starts diving ascending at a rate of 25 feet per minute for 2 minutes.
Let's assume the ascending position as positive.
So , The position at which the scuba driver will be after 2 minutes after seeing large fish is :
= 25 × 2
= 50 feet
So , the scuba diver's position relative to sea level after the 4.8 minutes will be :
= -57.4 + 50
= -7.4 feet
This meant Scuba driver is 7.4 feet below sea level.

At how many seconds s will the two bottles have the same amount of water if Jason and Pedro start drinking from each of their bottles at the same time ?
The time at which the two bottles will have the same amount of water, using linear functions, is of:
26 seconds.
What is a linear function?The slope-intercept representation of a linear function is given by the rule shown as follows:
y = mx + b
The coefficients of the function and their meaning are described as follows:
m is the slope of the function, representing the change in the output variable y when the input variable x is increased by one.b is the y-intercept of the function, which is the numeric value of the function when the input x is of zero.For the functions in this problem, we have that:
The slope is the rate of water they drink per second.The intercept is the initial amount of water that they have.Hence the functions are given as follows:
Jason: J(x) = 20 - x.Pedro: P(x) = 65 - 2.5x.The time at which they have the same amount is x for which:
P(x) = J(x)
65 - 2.5x = 20 - x
1.5x = 45
x = 45/1.5
x = 30 seconds.
However, at this time, the amount would be of:
J(30) = 20 - 30 = -10.
Which is a negative amount of water, not possible, hence they would have the same amount when Jason finishes, hence:
65 - 2.5x = 0
2.5x = 65
x = 65/2.5
x = 26 seconds.
Missing InformationThe problem is:
Jason's water bottle has 20 ounces of water, and he is drinking ata rate of 1 ouncer per second. Pedro's water bottle contains 65 bunces of water, and he is drinking at a rate of 2.5 ouncers per second. At how many seconds, s, will the two bottles have the same amount of water if Jason and Pedro start drinking from each of their bottles at the same time?

Function value at x = 1 [tex]f(1)[/tex] = 1 ,
Left Hand Derivative [tex]\lim_{x \to 1^-} f'(x)[/tex] = -6 and
Right Hand Derivative [tex]\lim_{x \to 1^+} f'(x)[/tex] = -6.
So, the function f(x) is neither continuous nor differentiable at x = 1.
Given, a piecewise function
3㏑(3 - 2x) + 3 for x < 1
f(x) =
-3x² + 4 for x ≥ 1
Now, for [tex]\lim_{x \to 1^-} f(x)[/tex] we will consider the function 3㏑(3 - 2x) + 3, as we have to find the Left Hand Limit of the function, at x = 1.
[tex]\lim_{x \to 1}[/tex] 3㏑(3 - 2x) + 3 = 3㏑(3 - 2(1)) + 3
= 3 ㏑(1) + 3
= 0 + 3
= 3
Now, for [tex]\lim_{x \to 1^+} f(x)[/tex] we will consider the function -3x² + 4, as we have to find the Right Hand Limit of the function, at x = 1.
[tex]\lim_{x \to 1}[/tex] -3x² + 4 = -3(1)² + 4
= -3 + 4
= 1
Now, for [tex]f(1)[/tex] we will consider the function -3x² + 4,
[tex]f(1)[/tex] = -3(1)² + 4
= -3 + 4
= 1
Now, for [tex]\lim_{x \to 1^-} f'(x)[/tex] we will consider the derivative of the function
3㏑(3 - 2x) + 3,
[tex]\lim_{x \to 1}[/tex] -6/(3 - 2x) = -6/(3 - 2(1))
= -6
Now, for [tex]\lim_{x \to 1^+} f'(x)[/tex] we will consider the derivative of the function
-3x² + 4,
[tex]\lim_{x \to 1}[/tex] -6x = -6(1)
= -6
So, the function f(x) is neither continuous nor differentiable at x = 1.
Hence, [tex]\lim_{x \to 1^-} f(x)[/tex] = 3 , [tex]\lim_{x \to 1^+} f(x)[/tex] = 1 , [tex]f(1)[/tex] = 1 , [tex]\lim_{x \to 1^-} f'(x)[/tex] = -6 and [tex]\lim_{x \to 1^+} f'(x)[/tex] = -6

What mixed number is represented on the number line shown here?
Answer:
The mixed number is 1 and 2/5. If it is split into 5 parts.
Step-by-step explanation:
No explanation sorry!
Answer:
Step-by-step explanation:
We already know how to represent whole numbers on the number line. Let us consider the image shown, here, the digits 0 and 1 are represented on the number line.
Representation of 0 and 1 on The Number Line
If we divide the number line into two equal parts, as shown in the figure below, what value does that mid-point hold? Half of what the graduation between 0 and 1 holds.
So, the point represents (1-0)/2 = ½
Fraction - Representation Of Fraction On The Number Line
Thus we saw, to represent a fraction on the number line, we need to divide the line segment between two whole numbers into n equal parts where n represents the denominator of the fraction. For example, if we have to represent the fraction 1/5 on the number line, hence, we need to divide the line segment between 0 and 1 into five equal parts, where the first point as shown in the figure represents the fraction 1/5, the second represents 2/5 and so on.
Fraction Representation
We must note that, 0/5 = 0 here and 5/5 = 1.
Here you have seen the representation of proper fraction on the number line. To represent improper fractions, you first convert them into mixed fractions. The same procedure, as shown above, is used with the whole number as the starting point.

A new car costs $24,250, which is approximately 110% of what a comparable car cost 3 years ago. What did the car cost 3 years ago?
The car's cost 3 years ago was $22,045.45.
According to the question,
We have the following information:
A new car costs $24,250, which is approximately 110% of what a comparable car cost 3 years ago.
Now, let's take the cost of car 3 years to be $x.
So, we have the following expression:
110% of x = 24250
110x/100 = 24250
Using the cross multiplication method:
110x = 24250*100
Dividing both sides by 110 will give us the value of x which is the required cost of car:
x = 2425000/110
x = $22045.45
Hence, the car's cost 3 years ago was $22,045.45.

A number line is a mathematical visual representation of numbers on a straight line. The digits on a number line are positioned sequentially at regular intervals throughout its length. It frequently appears horizontally and might go on forever in any direction.
As seen from the number line, point A is one unit left of -1 which is -2. Since each mark is a difference of 1 and to the left is a negative value, point B is midway between -1 and 0 is half of -1 which is -0.5, point C is midway between 0 and 1 is basically half of 1 which is 0.5 and point D is halfway between 1 and 2 is exactly that 1.5
As per the numerical values of the given points, the two that are opposites to each other are points B and C. They both have a value of 0.5 on each end of the number line, one being negative while the other is positive, thus they are opposites of each other.
