The population of Charlotte, North Carolina, in 2013 was approximately 775,000. If the annual rate of growth is about 3. 2% what is an approximation of Charlotte’s population in 2000
Charlotte, North Carolina had an approximate population of 531,145 in 2000.
To approximate Charlotte's population in 2000, we can use the formula for exponential growth:
P(t) = [tex]P0 \times e^{(rt)[/tex]
where P(t) is the population at time t, P0 is the initial population, r is the annual rate of growth as a decimal, and e is the mathematical constant e (approximately 2.71828).
Let's let t = 13 be the number of years between 2000 and 2013. We know that P(13) = 775,000, and r = 0.032. We can solve for P0 as follows:
775,000 = [tex]P0 \times e^{(0.03213)[/tex]
P0 = [tex]775,000 / e^{(0.03213)[/tex]
Using a calculator, we can approximate P0 as:
P0 ≈ 531,145
Therefore, an approximation of Charlotte's population in 2000 is 531,145.

In Princeton, the library is due south of the courthouse and due west of the community swimming pool. If the distance between the library and the courthouse is 7 miles and the distance between the courthouse and the city pool is 8 miles, how far is the library from the community pool? If necessary, round to the nearest tenth.
Please respond.
Thank you!
Answer:
3.87 miles
Step-by-step explanation:
The attached figure gives the relative locations of the courthouse, the library and the pool.
The three locations represent a right triangle with the distance between courthouse - pool as the hypotenuse and the distance between courthouse - library as the vertical leg
By the Pythagorean theorem if c is the hypotenuse and a, b the other two legs
[tex]c^2 = a^2 + b^2[/tex]
a = distance between courthouse and library = 7 miles
c = distance between courthouse and pool = 8 miles
and we have to find b
So plugging in known values
[tex]8^2 = 7^2 + b^2\\\\b^2 = 8^2 - 7^2\\\\b^2 = 64 - 49\\\\b^2 = 15\\\\b= \sqrt{15} = 3.87298 \approx 3.87 \;miles[/tex]

The cot(cos−1(a))= a/√(1-a^2).
Value of cos(sin−1(1)): Let's assume that θ= sin−1(1). It means that sinθ= 1. The value of θ is π/2, therefore we can say that cos(sin−1(1))=cos(π/2)= 0b) Value of tan(cos−1(-23)): Let's suppose that θ= cos−1(-23). It implies that cosθ= -23/25. As we know that tanθ= sinθ/cosθ, Therefore;tan(cos−1(−23))= sin(θ)cos(θ) = -24/25.2. a) Value of sin(cos−1(3/2)): Let's suppose that θ= cos−1(3/2). It implies that cosθ= 3/2. As we know that sin^2θ= 1- cos^2θ, Therefore;sin(cos−1(3/2))= √(1- (3/2)^2)= √(1/4)= 1/2.b) Value of csc(tan−1(-5/1)): Let's assume that θ= tan−1(-5/1). It implies that tanθ= -5/1. As we know that cscθ= 1/sinθ, Therefore;csc(tan−1(−51))= 1/sin(θ)= 1/√(1+tan^2θ) = 1/√(1+25)= -1/√26.3. a) Value of sin(tan−1(a^2)): Let's suppose that θ= tan−1(a^2). It implies that tanθ= a^2. As we know that sinθ= tanθ/√(1+tan^2θ), Therefore;sin(tan−1(a2))= (a^2)/√(1+(a^4)).b) Value of cot(cos−1(a)): Let's suppose that θ= cos−1(a). It implies that cosθ= a.

d) Decrease 500 ml by 25% and then increase by 10%.
Answer: 412.5 ml
Step-by-step explanation:
500 ( 1 - 25%) ( 1 + 10%)
= 412.5 ml
Answer:
412.5 ml
Step-by-step explanation:
To decrease 500 ml by 25%, you would need to multiply 500 by 0.25 to find the amount of decrease:
500 × 0.25 = 125 mlSubtract that amount from the original value:
500 - 125 = 375 ml.Therefore decreasing 500 ml by 25% would give us 375 ml.
To then increase this value by 10%, you would multiply it by 0.10 to find the amount of increase:
375 × 0.10 = 37.5 mlNow, add that amount to the previous value:
375 + 37.5 = 412.5 ml.Therefore, if you decrease 500 ml by 25% and then increase it by 10%, the final result is 412.5 ml.

What is the intermediate step in the form (x+a)^2=b as a result of completing the square for the following equation? X^2+22x=8x-53
The intermediate step in the form (x+a)²=b as a result of completing the square is: (x + 7)² = -4. We can calculate it in the following manner.
To complete the square for the equation x² + 22x = 8x - 53, we need to move the constant term to the right side and the linear term to the left side, and then add a constant value to both sides so that the left side becomes a perfect square trinomial. The steps are as follows:
x² + 22x = 8x - 53 (original equation)
x² + 14x = -53 (subtract 8x from both sides)
x² + 14x + (14/2)² = -53 + (14/2)² (add (14/2)² to both sides)
x² + 14x + 49 = -53 + 49 (simplify)
(x + 7)² = -4 (factor the left side and simplify the right side)
So the intermediate step in the form (x+a)²=b as a result of completing the square is:
(x + 7)² = -4
Note that this equation has no real solutions, since the square of any real number is always nonnegative, whereas the right side of this equation is negative.

The value of x:z = 1:4.
To find the ratio of x to z, we need to have a common term between x, y, and z. Since we have y in both ratios, we can use it as the common term.
From the given ratios:
x:y = 3:4
y:z = 1:3
We can see that the y in the first ratio and the y in the second ratio are the same.
To find the ratio of x to z, we can "connect" the two ratios by canceling out the y:
x:y = 3:4
y:z = 1:3
x:y × y:z = 3:4 × 1:3
x:z = 3:12

Step-by-step explanation:
The x and y intercept of a function (say the x intercept), is when y = 0 and vice versa.
The x intercept in this function is when y = 0
Thus,
4x-0=-4
4x = -4
x = -1.
So the x- intercept point = (-1, 0)
Similarly,
4(0)-y= -4
(x is equated to 0 to find the y - intercept)
-y = -4
∴ y = 4
y- intercept point = (0, 4)

What is the best prediction for the number of times the spinner will not land on an elephant?
We might estimate that 0.8n is the approximate prediction number of times it won't land on the elephant.
We need to know the likelihood that the spinner will land on an elephant as well as the total number of spins in order to anticipate the number of times it won't.
Assume the spinner contains five equal parts, one of which is decorated with an elephant. The likelihood of the spinner touching the elephant is then 1/5, or 0.2.
If we know the total number of spins, we can use the likelihood that the spinner will fall on an elephant to calculate the likelihood that it won't. 1 - 0.2 = 0.8 is the probability that the spinner will miss the elephant.
Hence, if we suppose that the spinner is spun n times, we may estimate that 0.8n is the approximate number of times it won't land on the elephant. The prediction of probability of the spinner landing on the elephant is assumed to be constant for each spin and that each spin is independent of the others.

A triangle has an angle that measures 35°. The other two angles are in a ratio of 13:16. What are the measures of those two angles?
Answer:
Let's denote the measures of the other two angles by 13x and 16x, where x is a constant.
Since the sum of the angles in a triangle is always 180 degrees, we can write an equation:
35 + 13x + 16x = 180
Simplifying this equation, we get:
29x = 145
x = 5
Therefore, the measures of the other two angles are:
13x = 13(5) = 65 degrees
16x = 16(5) = 80 degrees
So, the measures of the other two angles are 65 degrees and 80 degrees.
Step-by-step explanation:
f(x)= 6x^{3} -\sqrt{2}x^{2} -10x-4\sqrt{2} and the zeros are 2 under the root find all other zeros
Therefore, the other two zeros of the function are approximately -1.802 and -0.198.
What is equation?An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides separated by an equal sign (=). The expressions on both sides of the equation can contain variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. The goal in solving an equation is to find the value of the variable that makes the equation true. Equations are used extensively in mathematics and science to model real-world phenomena and solve problems.
by the question.
To find the zeros of the function, we need to solve the equation F(x) = 0. Since the given function has one known zero, which is 2 under the root, we can use this to simplify the expression.
Let's start by factoring out (x - 2^(1/2)) from the expression:
[tex]F(x) = (x - 2^(1/2))(6x^2 + 12x + 2^(1/2) - 4\sqrt{2})[/tex]
Now we need to find the zeros of the quadratic factor:
[tex]6x^2 + 12x + 2^(1/2) - 4\sqrt{2} = 0[/tex]
Using the quadratic formula, we get:
[tex]x = [-12±\sqrt((12)^2 - 4(6)(2^(1/2) - 4\sqrt{2}))]/(2(6))[/tex]
Simplifying the expression under the square root gives:
[tex]\sqrt((12)^2 - 4(6)(2^(1/2) - 4\sqrt{2})) = \sqrt(144 - 24\sqrt{2} - 96) = sqrt(48 - 24\sqrt{2})[/tex]
So, the zeros of the function are:
[tex]x = 2^(1/2), (-1 -\sqrt{6 + 3\sqrt{2}})/3, (-1 + \sqrt{6 + 3\sqrt{2}})/3[/tex]
