Answer:
(-1373)
Step-by-step explanation:
a = 1st term = -13
Common difference = d = 2nd term - 1st term
d = -33 - (-13) = -33 + 13
d = -20
n = 69
nth term = a + (n-1)d
69th term = (-13) + 68 * (-20)
= -13 - 1360
= - 1373

Find the radius of convergence, R, of the series.
a. [infinity] b. sum.gif
c. n = 1
d. x^n
e. n^43^n
R = 1/3.
a. R = Does not converge
b. R = Cannot be determined without knowing the value of sum.gif
c. R = 1
d. R = 1
e. R = 1/3
To find the radius of convergence, R, of the series, we need to use the ratio test. The series is given by:
sum(n=1 to infinity) of a_n
where a_n is given by:
a_n = x^n * n^43^n
Applying the ratio test, we get:
lim (n → ∞) |a_n+1 / a_n| = lim (n → ∞) |x^(n+1) * (n+1)^43 * 3^(n+1) / (x^n * n^43 * 3^n)|
= lim (n → ∞) |x * (n+1)^43 * 3 / n^43|
= |x| * lim (n → ∞) ((n+1)/n)^43
= |x|
The series converges if the limit is less than 1 and diverges if the limit is greater than 1. Therefore, we need to solve the inequality |x| < 1 to find the radius of convergence, R.
a. If x = infinity, then the series diverges.
b. If x = sum.gif, then the series converges if |sum.gif| < 1. We cannot simplify this expression further without knowing the value of sum.gif.
c. If x = 1, then the series becomes:
sum(n=1 to infinity) of n^43
This is a p-series with p = 43 > 1, which converges. Therefore, R = 1.
d. If x = -1, then the series becomes:
sum(n=1 to infinity) of (-1)^n * n^43
This is an alternating series with decreasing terms. We can apply the alternating series test to show that it converges. Therefore, R = 1.
e. If x = 3, then the series becomes:
sum(n=1 to infinity) of n^43 * 3^n
This is a geometric series with a common ratio r = 3 > 1. Therefore, the series diverges.

How do you divide fast without a calculator?
The simplest way to perform a division is long division and synthetic division.
What is division?
Division in mathematics is the process of dividing an amount into equal parts. For instance, we may split a group of 20 people into four groups of 5, five groups of 4, and so on.
There are two methods to perform division:
Long division: The mathematical procedure for splitting big numbers into more manageable groups or sections is known as long division. A difficulty can be solved by breaking it down into manageable parts. Dividends, divisors, quotients, and remainders all exist in long divisions.
Synthetic division: In algebra, synthetic division is a technique for manually dividing polynomials according to Euclid, requiring less writing and calculation than long division. Although the approach can be applied to division by any polynomial, it is often taught for division by linear monic polynomials.

The numerator can be written as
\(h^{-1}\)combining part one and two

Simplifying the numerator

Which method of solving for the variable could be used instead of cross multiplication?
O distributing x + 3 and then 3x + 5 to both sides of the equation
distributing x-3 and then 3x-5 to both sides of the equation
using the multiplication property of equality to multiply both sides of the equation by 10
using the multiplication property of equality to multiply both sides of the equation by 10
The method that could be used instead of cross multiplication to solve the equation *3-3x+5 is distributing x + 3 and then 3x + 5 to both sides of the equation.
Instead of using cross multiplication, one alternative method to solve the equation *3-3x+5 is to distribute x + 3 and then 3x + 5 to both sides of the equation.
To explain this method, let's consider the equation step by step:
Original equation: *3-3x+5
Cross multiplication: 5(x+3) = 2(3x+5)
Distributive property: 5x + 15 = 6x + 10
Subtraction property of equality: 5x - 6x = 10 - 15
Simplification: -x = -5
Multiplication property of equality: (-1)(-x) = (-1)(-5)
Simplification: x = 5
Now, instead of cross multiplication, we can distribute x + 3 and then 3x + 5 to both sides of the equation:
Original equation: *3-3x+5
Distributive property: 5(x + 3) = 2(3x + 5)
Expanding the expressions inside the parentheses:
5x + 15 = 6x + 10
Now we can proceed with solving the equation as before:
Subtraction property of equality: 5x - 6x = 10 - 15
Simplification: -x = -5
Multiplication property of equality: (-1)(-x) = (-1)(-5)
Simplification: x = 5
By distributing x + 3 and 3x + 5 to both sides of the equation, we obtain the same result as the original method. This alternative method is another way to solve the equation without using cross multiplication.

Step-by-step explanation:
Find the equation of the line that passes through (4.-1.5) and is parallel to a line that passes through (0, 2) and (5, 4).
Answer:
y = 2/5 x - 3.1
Step-by-step explanation:
Slope of the line passing through the points (0, 2) and (5, 4) = (4-2)/(5 - 0) = 2/5
Since required line is parallel to the line passing through the points (0, 2) and (5, 4).
Therefore, slope of required line (m) = 2/5
Required line passes through the point ( 4, - 1.5)
Therefore equation of line in slope point form is given as.
y - (-1.5) = m(x-4)
y + 1.5 = 2/5(x - 4)
5y + 7.5 = 2x - 8
5y = 2x - 8 - 7.5
5y = 2x - 15.5
y = 2/5 x - 3.1

Let ( f(x)=frac{1}{x-3} ) and ( g(x)=frac{6}{x}+3 ) Find the following functions. Simplify your answers. [ f(g(x))= ] [ g(f(x))= ]
"
f(g(x)) simplifies to x/6.
g(f(x)) simplifies to 6x - 15.
To find the composition of functions f(g(x)) and g(f(x)), we substitute the expression for g(x) into f(x) and vice versa.
f(g(x)):
Replace x in f(x) with g(x):
f(g(x)) = f(6/x + 3)
Now, we substitute the expression for g(x) into f(x):
f(g(x)) = f(6/(x) + 3) = 1/(6/(x) + 3 - 3) = 1/(6/(x)) = x/6
Therefore, f(g(x)) simplifies to x/6.
g(f(x)):
Replace x in g(x) with f(x):
g(f(x)) = g(1/(x-3))
Now, we substitute the expression for f(x) into g(x):
g(f(x)) = g(1/(x-3)) = 6/(1/(x-3)) + 3 = 6(x-3) + 3 = 6x - 18 + 3 = 6x - 15
Therefore, g(f(x)) simplifies to 6x - 15.

The radius of the sphere with a volume of 4,500π cubic inches is 15 inches, not 2,000 inches as the student had incorrectly calculated.
What is volume?
Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
The volume of the sphere is given as 4,500π cubic inches.
The formula for volume of the sphere is -
V= 4/3πr³
Substituting the values in the equation -
4,500π = 4/3πr³
4,500 = 4/3r³
The mistake in the student's calculation is in the step where they simplified 4/3πr³ to 4,500.
To correct this, we need to isolate r³ by dividing both sides by 4/3 -
4,500 = (4/3)r³
4,500 ÷ (4/3) = r³
4,500 × 3/4 = r³
3,375 = r³
Then, we can take the cube root of both sides to find r -
r = ∛3,375 = 15
Therefore, the radius of the sphere is 15 inches.

Start with 4x-9<7
You want to get the variable alone. Since 9 is negative add it to both sides
4x-9(+9)<7(+9)
4x<16
You have to divide the 4 from both sides for the variable to be alone.

Ms. Bell's mathematics class consists of 6 sophomores, 11 juniors, and 13 seniors. The task is to determine the number of different ways Ms. Bell can create a 5-member committee of seniors, with each senior having an equal chance of being selected.
To solve this problem, we can use combinations. The number of ways to select a committee of 5 seniors from a group of 13 can be calculated using the combination formula:
C(n, k) = n! / (k!(n - k)!)
Where n represents the total number of elements (seniors in this case), and k represents the number of elements to be selected (5 in this case). The exclamation mark denotes the factorial of a number.
Using the combination formula, the number of ways to select a 5-member committee from 13 seniors is:
C(13, 5) = 13! / (5!(13 - 5)!) = 13! / (5! * 8!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287
