Describe and correct the error a student made in writing the exponential function.
Starting value 6
Constant ratio - 1/3
f(x) = 6(1/3)^x
f(x)=2^x
The correct equation of exponential function is [tex]f(x) = 6 * (\frac{1}{3} )^x[/tex]
What is an exponential function?
An exponential function is one that has the formula f (x) = [tex]a^{x}[/tex], where x is a variable and a constant that serves as the function's base and must be greater than 0.
Given,
starting value = 6
constant ratio = 1/3
The general form of an exponential function
[tex]f(x) = ab^{x}[/tex]
where a = starting value i.e when x = 0
b = rate of change in exponential equation
So substituting our given values in the above equation, the exponential function is
[tex]f(x) = 6 * (\frac{1}{3} )^x[/tex]
Now the value 6 can be divided by 3 only if the value of x = 1
[tex]f(1) =\frac{6}{3} = 2[/tex]
If x = 5, then equation becomes,
[tex]f(5) = 6 * (\frac{1}{3} )^5 = \frac{2}{81}[/tex]
So we cannot simply divide 6 by 3 without considering the value of x.
Therefore the correct equation of exponential function is

What is integration ?
Integration is a process of finding an antiderivative of a function, it is the reverse process of differentiation. It can be thought of as the area under the curve of the function or the accumulation of the function over a certain interval.
Integration by parts is a technique that can be used to integrate a wide variety of functions, not only functions that include polynomials or exponential functions. In fact, integration by parts can be used to integrate any function that can be expressed as the product of two functions, where one of the functions is the derivative of the other function. In other words, integration by parts allows us to evaluate an integral of the form ∫u(x)dv(x)dx by expressing it in terms of an integral of the form ∫v(x)du(x)dx.
It's just that those types of functions are more commonly used when applying this technique.

The questions below can be solved using the relation between angular size, physical size and distance. For the questions below, provide a complete solution with explanation.
1. Find the Sun's diameter. The sun has an angular diameter of about 0.5° and an average distance from the Earth of about 150 million km. What is the sun's approximate physical diameter? Compare your
answer to the actual value of 1 390 000 km.
2. Find a Star's Diameter. The supergiant star Betelgeuse (in the constellation Orion) has a measured angular diameter of 0.040 arcsecond from Earth and a distance from Earth of 720 light-years. What is the actual diameter of Betelgeuse? Compare your answer to the size of our Sun and the Earth-Sun distance.
The physical diameter of the sun will be 1309000km and the percentage of difference between the diameters will be 5.8%.
How to calculate the diameter?From the information, the sun has an angular diameter of about 0.5° and an average distance from the Earth of about 150 million km. The angular diameter in radians will be:
= 0.5π / 180
= 0.008727 radians
Distance from the sun = 150 × 10^6
The physical diameter of the sun will be:
= 150 × 10^6 × 0.008727
= 1309000km
The difference between the diameters will be:
= 1390000 - 1309000
= 8.1 × 10^4.
The percentage of difference will be:
= (8.1 * 10^4) / 1390000 × 100
= 5.8%

Given A = 5i +7j , B= 2i +3j Find the magnitude of A-B Select one: a.6 0 b. 5 c. 2 d. 4
In order to find the magnitude of a vector, we use the Pythagorean theorem. The magnitude, also known as the length or the norm, of a vector, is the square root of the sum of the squares of its components.
In this case, we are given two vectors A and B, which are defined as
A = 5i + 7j
B = 2i + 3j.
The i and j components represent the x and y values of the vector respectively.
To find the magnitude of vector A-B, we need to first find the difference between the two vectors. This can be done by subtracting the components of vector B from the corresponding components of vector A. So,
A-B = (5i + 7j) - (2i + 3j) = 3i + 4j.
Now we can use the Pythagorean theorem to find the magnitude of this vector. The square root of the sum of the squares of the x and y components of the vector is the magnitude of the vector. So, the magnitude of
A-B = √(3^2 + 4^2)
A-B = √(9 + 16)
A-B= √25
A-B = 5. Therefore, the answer is (b) 5.

the points (17,10) and (8,10) fall on a particular line. what is its equation in slope-intercept form?
The equation of the line that passes through the points (17,10) and (8,10) is y = 10.
What is slope?Slope is a measure of the steepness of a line or a linear function. It is often represented by the letter "m" and is calculated as the ratio of the change in the y-coordinates of two points divided by the change in the x-coordinates of those same two points. In other words, it is the ratio of the "rise" to the "run" of the line. The slope of a line can be positive, negative, zero, or undefined.
What is slope intercept form?The slope-intercept form of a linear equation is a way to represent the equation of a line in the form of y = mx + b, where m is the slope and b is the y-intercept of the line. The y-intercept is the point where the line crosses the y-axis, and it is represented by the value of b. This form of the equation is useful because it allows us to easily identify the slope and y-intercept of a line, as well as to graph the line using these values.
Calculate the slope (m) using the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of the two points.
In this case, the slope is:
m = (10 - 10) / (8 - 17) = 0
Use the point-slope form of the equation, y - y1 = m(x - x1)
In this case, the point slope form is:
y - 10 = 0(x - 17)
Simplify the above equation, we get:
y = 10
The equation of the line in slope-intercept form is:

-3 = a1 + b2
-1 = a2 + b(-1)
1 = a*(-2) + b*1
Solving this system of equations, we get:
a = 5
b = -1
Therefore, z can be written as a linear combination of the vectors in S as:
z = 5*(1, 2, −2) -1*(2, −1, 1)

v = as1 + bs2
Here, we can find the values of a and b by solving the following system of equations:
-2 = a1 + b2
-5 = a2 + b(-1)
5 = a*(-2) + b*1
Solving this system of equations, we get:
a = -2
b = 7
Therefore, v can be written as a linear combination of the vectors in S as:
v = -2*(1, 2, −2) + 7*(2, −1, 1)
(c) w = (1, −23, 23)
we can write w as a linear combination of the vectors in S by using the following equation:
w = as1 + bs2
Here, we can find the values of a and b by solving the following system of equations:
1 = a1 + b2
-23 = a2 + b(-1)
23 = a*(-2) + b*1
Solving this system of equations, we get:
a = -12
b = 11

Answer:
6
Step-by-step explanation:
For dividing fractions it's also useful to know that the first fraction (3/4) is called the dividend and the second fraction (1/8) is called the divisor.
Here is a really quick way to divide fractions. In the divisor (the second fraction) we flip the numerator and the denominator. This is known as the reciprocal and basically it means the reverse of the fraction. When we find the reciprocal, we also have to change the division sign to a multiplication sign:
3/4 times 8/1
Once you've flipped the second fraction and changed the symbol from divide to multiply, we can multiply the numerators together and the denominators together and we have our solution:
So we multiply the numerators: 3x8=24
Then multiply the denominators: 4x1=4
Then we have the inproper fraction 24/4
So we divide 24 by 4 to make the answer a proper fraction
Finally you get your answer 6!
The measure of an angle is 89
Find the measure of its supplement.
We can conclude that the supplement angle of 89° will be 91°.
What do we mean by supplement angles?Angles that add up to 180 degrees are referred to as supplementary angles.
For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°.
The sum of complementary angles is 90 degrees.
Two angles are complementary if their sum equals 90 degrees, and supplementary if their sum equals 180 degrees.
So, we have an angle of 89°.
We know that the supplement angle is an angle of measure 180°.
Now, the supplement angle of 89° will be as follows:
180 - 89
91°
Therefore, we can conclude that the supplement angle of 89° will be 91°.
