If $12,000 is invested at 7% for 9 years, find the future value if the interest is compounded daily.
The future value is 6,495,554.308.
What has compounded annually?
The interest charged on a loan or deposit is known as compound interest. It is the idea that we use the most frequently on a daily basis. Compound interest is calculated for an amount based on both the principal and cumulative interest. The main distinction between compound and simple interest is this.
Compound interest can be calculated in math in a variety of ways depending on the circumstances. To make the calculations simpler, we can use the compound interest formula. We need to know the amount and the principal in order to calculate compound interest. The distinction is between the amount and the principal.
Given that $12,000 is invested in a project at 7% for 9 years.
The formula of compound interest is
A = P(1+r/n)^nt
A = amount
P = principal
r = rate of interest
t = time
n = number of compound interest per annum
For the given problem:
P =12,000, r = 7%, t = 9, n = 365:

The probability that a randomly selected cat has no treatment and no fleas is 43/87.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Total number of cats = (cats sprayed with flea deterrent + cats with no treatment)
= (33+6 + 43+5)
=87
we need to find the number of cats with no treatment and no fleas, and divide it by the total number of cats.
Now we can see that the number of cats with no treatment and no fleas is 43.
Therefore, the probability that a randomly selected cat has no treatment and no fleas is:
P(no treatment and no fleas) = number of cats with no treatment and no fleas / total number of cats
= 43 / 87
Hence, the probability that a randomly selected cat has no treatment and no fleas is 43/87.

Haris Rauf is the star fast bowler for Pakistan. Harry Brook is a talented young batter of English
team. When Haris Rauf decides to bowl a yorker, 80% of the time he is able to execute the yorker
perfectly and 20% of the time it turns into a full toss. When Harry Brook faces a yorker, he hits it
for a boundary 20% of the time. When Harry Brook faces a full toss, he hits it for a boundary 90%
of the time. Haris Rauf is bowling the last ball of the innings to Harry Brook. Before running in to
bowl this last ball, Haris Rauf has decided to bowl a yorker, what is the probability that a boundary
will be scored of this last ball of the innings.
Answer:
To solve it, you need to use probability. Let me show you how.
We can use a tree diagram to represent the possible outcomes of the last ball. Here is the diagram:
```
Haris Rauf
/ \
yorker full toss
0.8 0.2
/ \ / \
boundary no boundary boundary no boundary
0.2 0.8 0.9 0.1
```
The probability of a boundary is the sum of the probabilities of the branches that end with a boundary. To find the probability of each branch, we multiply the probabilities along the branch. For example, the probability of a yorker and a boundary is 0.8 × 0.2 = 0.16.
So, the probability of a boundary is:
0.8 × 0.2 + 0.2 × 0.9 = 0.16 + 0.18 = 0.34
Therefore, the probability that a boundary will be scored of the last ball is 0.34 or 34%.

Help me with this quadratic functions graph
The graph of the quadratic function is given below.
What are Quadratic Functions?Quadratic functions are polynomial functions consisting of variables and exponents and the degree of the variable is 2.
The general form of a quadratic function is f(x) = ax² + b x + c.
Given is a quadratic function.
y = 3x² + 1
We know that graph of a quadratic function is a parabola.
Since the leading coefficient is +3, positive. So the graph opens upward.
Vertex = (-b/2a, f(-b/2a))
-b/2a = -0/(2 × 3) = 0
f(-b/2a) = (3 × 0) + 1 = 1
(0, 1) is the vertex.
x = 1, then y = 3 + 1 = 4
x = -1, then y = 3 + 1 = 4
x = 2, then y = 12 + 1 = 13
x = -2, then y = 12 + 1 = 13
x = 3, then y = 27 + 1 = 28
x = -3, then y = 27 + 1 = 28
Some of the points are (-3, 28), (-2, 13), (-1, 4). (0, 1), (1, 4), (2, 13) and (3, 28).

10. Find the base of the function F(x)=b^x, if its graph contains the point (1/3,2). A. 3square root 2 B.square root 1/3 C. 8 D. 2square root 2
Answer:
Step-by-step explanation:
To find the base of the exponential function F(x) = b^x, we need to use the information that its graph contains the point (1/3, 2). We can use this information to solve for b.
Since the graph passes through the point (1/3, 2), we can set x = 1/3 and y = 2 in the equation F(x) = b^x:
b^(1/3) = 2
Taking the cube root of both sides, we get:
b = (2)^3 = 8
So the base of the exponential function F(x) = b^x is b = 8, which means the correct answer is C) 8.

The domain of f * g is the set of all real numbers x such that x ≤ 6.
In interval notation, we can write:
Domain of f * g = (-∞, 6].
What is the domain of the function?
The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.
The domain of the function f(x) = √(6-x) is the set of all real numbers x such that 6-x ≥ 0, which is x ≤ 6.
The domain of the function g(x) = x² - x is the set of all real numbers x, since there are no restrictions on the input.
To find the domain of the function f * g, we need to consider the values of x for which the expression f(x) * g(x) is defined.
We have:
f(x)g(x) = √(6-x)(x² - x)
The expression is defined only if both factors are defined.
For the first factor, √(6-x) to be defined, we need 6-x ≥ 0. This means that x ≤ 6.
For the second factor, x² - x to be defined, there are no restrictions on the input.
Therefore, the domain of f * g is the set of all real numbers x such that x ≤ 6.

A sorting algorithm is defined as an algorithm that sorts the elements of a list. The most commonly used sequences are numerical sequence and lexicographical sequence, ascending or descending.
A sorting algorithm is used to reorder an array or list of elements according to an element comparison operator. Comparison operators are used to define a new order of elements in that data structure. Consider example, The above list of characters is sorted in ascending order by their value. That is, characters with lower values are placed before characters with higher values. It is important in real life because it supports the development of the scientific concept that things can be owned and organized into distinct groups (e.g. creatures, cars, weather types, etc.). We will now discuss some real-world examples of using sorting algorithms.
1) Your phone's contact list is sorted. This means that your data is organized in this way so you can easily access the contacts you want from your phone. That is, "I ordered."
2) Paper sorting : Imagine a teacher sorting students' work alphabetically by student name. This type of operation is similar to the functionality of sorting algorithms such as bucket sort. Sorting is more efficient process.
3) Traffic lights : Traffic lights are a good example of how algorithms are used in the real world around us. Next time you get stuck in a car at a red light, think about the algorithm that traffic lights run." Most traffic lights don't automatically switch between green, yellow, and red.

Solving the provided question, we can say that By, Pythagorean theorem PR = √277 and b = 11.31
What is Pythagorean theorem?The Pythagοrean Theorem, sometimes known as the Pythagοrean Theorem, is the basic Euclidean geοmetry relationship between a right triangle's three sides. Accοrding to this rule, the area of a square with the hypotenuse side equals the sum οf the areas of squares with the other twο sides. The Pythagοrean Theorem, often knοwn as the generic algebraic nοtation a² + b² = c², states that the square that crοsses the hypotenuse οf a right triangle οpposite the right angle equals the sum of the squares that span the sides of a right triangle.
By, Pythagοrean theorem
PR² = PQ² + QR²
PR² = 14² + 9²
PR² = 196 + 81
PR = √277
Again by Pythagorean theorem
c² - a² = b²

The price of a math book after a discount of 25% is $30.
Answer:
7.5dollars
Step-by-step explanation:
25%/100×$30
A positive integer is 3 less than another. If the sum of the reciprocal of the smaller and
twice the reciprocal of the larger is 9/10 then find the two integer
Let's call the smaller integer "x". Then the larger integer would be "x + 3".
The sum of the reciprocal of the smaller integer and twice the reciprocal of the larger integer is 9/10, so we can write that as:
1/x + 2/(x + 3) = 9/10
Expanding and simplifying the right side:
1/x + 2/(x + 3) = 9/10
(x + 6)/(x * (x + 3)) = 9/10
10(x + 6) = 9x * (x + 3)
10x + 60 = 9x^2 + 27x
9x^2 - 83x + 60 = 0
Now we have a quadratic equation that we can solve using the quadratic formula or by factoring. Since the coefficients are integers, we can try factoring:
(3x - 20)(3x - 3) = 0
So either 3x - 20 = 0 or 3x - 3 = 0, which means either x = 20/3 or x = 3. Since x must be a positive integer, the only solution is x = 3.
So the two integers are 3 and 3 + 3 = 6.

What is a linear equation?
A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.
The data points are given for the equation.
Consider the first two points (-2,-3) and (-1,-1).
The slope intercept form of the linear equation is -
y = mx + b
Here m is the slope.
For calculation of slope the formula is -
m = (y2 - y1) / (x2 - x1)
Substitute the values in the equation -
m = [(-1) - (-3)] / [(-1) - (-2)]
m = (-1 + 3) / (-1 + 2)
m = 2/1 = 2
The equation becomes y = 2x + b.
Substitute the point (-2,-3) to get the value of b.
y = 2x + b
-3 = 2(-2) + b
-3 = -4 + b
b = -3 + 4
b = 1
Therefore, the linear equation is y = 2x + 1.

A city's population is currently 365,000. If the population doubles every 24 years, what will the population be 96 years from now?
Answer:
5,840,000
Step-by-step explanation:
Let P be the population after x years. The population after 24 years is 2P. So, we have:
P = 365,000 * 2^(x/24)
To find the population after 96 years, we plug in x = 96:
P = 365,000 * 2^(96/24) = 365,000 * 2^4 = 365,000 * 16 = 5,840,000
So, the population of the city will be 5,840,000 after 96 years.

LITTLE BIT Confuse i tried area formula which is x/360 pi (r)squred but wont work
The side length of the square with the same area as the circle is given as follows:
9.75 cm.
What is the area of a circle?The area of a circle of radius r is given by π multiplied by the radius squared, as follows:
A = πr²
The radius for this problem is of 5.5 cm, hence the area of the circle is given as follows:
A = π x 5.5²
A = 95.03 cm².
For a square of side length s, the area is given by the side length squared, that is:
A = s².
Hence the desired side length is obtained as follows:
s² = 95.03
s = sqrt(95.03)
s = 9.75 cm.
