22nd term: -2, -5, -8, -11, -14
Answer:
The pattern goes by adding -3.
Using the arithmetic sequence, you can find the 22nd term.
[tex]t_{22} = -2+(22-1)(-3)\\t_{22} = -2+21*-3\\t_{22} = -2-63\\t_{22} = -65[/tex]

b. El empleado de una compania tiene un sueldo mensual de L. 23, 865,00, en el mes de marzo del 2019 se le hizo una rebaja
del 20% por llegadas tarde al trabajo. Cuanto se le dedujo? ¿Qué sueldo neto saco ese mes?
Ese mes se le dedujeron $4774, y cobró un sueldo de $19,092.
Cálculo de cantidadesDado que el empleado de una compañía tiene un sueldo mensual de L. 23, 865,00, y en el mes de marzo del 2019 se le hizo una rebaja del 20% por llegadas tarde al trabajo, para determinar cuánto se le dedujo y qué sueldo neto sacó ese mes se debe realizar el siguiente cálculo:
100 - 20 = 8023,865 x 0.80 = X19,092 = X23,865 - 19,092 = 4773Por lo tanto, ese mes se le dedujeron $4774, y cobró un sueldo de $19,092.

Eliana opened a savings account and deposited $300.00. The account earns 13% interest, compounded annually. If she wants to use the money to buy a new bicycle in 3 years, how much will she be able to spend on the bike?
Answer:
$432.87Step-by-step explanation:
Use below compound interest formula and the given data.
[tex]F = P*(1 + r)^{nt}[/tex]F- future amount, P- invested amount, r - interest rate, n - number of compounds, t- time
Given:
P = $300r = 13% or 0.13t = 3 yearsn = 1Find the amount after 3 years:
[tex]F = 300(1 + 0.13)^3 = 432.87[/tex]f(x) = x2
g(x) = 2x + 4
evaluate
f(-1) - g(2)
Answer:
–2x2 + 13
Step-by-step explanation:
( f o g)(x) = f (g(x))
= f (–x2 + 5)
= 2( ) + 3 ... setting up to insert the input formula
= 2(–x2 + 5) + 3
= –2x2 + 10 + 3
[tex] \rm\frac{13}8 + \sum \limits_{n = 0}^{ \infty } \frac{( - {1)}^{n + 1} (2n + 1)! }{n! (n + 2)! {4}^{2n + 3} } \\ [/tex]
Rewrite the factorial parts of the summand as
[tex]\dfrac{(2n+1)!}{n!(n+2)!} = \dfrac{(2n+1)(2n!)}{(n+2)(n+1)(n!)^2} = \dfrac{2n+1}{(n+2)(n+1)} \dbinom{2n}n[/tex]
where [tex]\binom nk[/tex] is the binomial coefficient, and [tex]\binom{2n}n[/tex] are the so-called central binomial coefficients.
Expand the rational expression into partial fractions:
[tex]\dfrac{2n+1}{(n+2)(n+1)} = \dfrac3{n+2} - \dfrac1{n+1}[/tex]
Pull out a constant factor and collect the exponential terms.
[tex]\dfrac{(-1)^{n+1}}{4^{2n+3}} = -\dfrac1{64} \left(-\dfrac1{16}\right)^n[/tex]
The sum we want is now
[tex]\displaystyle \frac{13}8 - \frac1{64} \sum_{n=0}^\infty \binom{2n}n \left(\frac3{n+2} - \frac1{n+1}\right) \left(-\frac1{16}\right)^n[/tex]
Let f(x) and g(x) be functions with power series expansions
[tex]\displaystyle f(x) = \sum_{n=0}^\infty \binom{2n}n \frac{x^n}{n+1}[/tex]
[tex]\displaystyle g(x) = \sum_{n=0}^\infty \binom{2n}n \frac{x^n}{n+2}[/tex]
and recall the well-known binomial series
[tex]\displaystyle \dfrac1{\sqrt{1-4x}} = \sum_{n=0}^\infty \binom{2n}n x^n[/tex]
which converges for |x| < 1/4.
Integrating both sides yields
[tex]\displaystyle \int \frac{dx}{\sqrt{1-4x}} = \int \sum_{n=0}^\infty \binom{2n}n x^n \, dx[/tex]
[tex]\displaystyle -\frac12 \sqrt{1-4x} = C_1 + \sum_{n=0}^\infty \binom{2n}n \frac{x^{n+1}}{n+1}[/tex]
Taking x = 0 on both sides, it follows that C₁ = -1/2. We then see that
[tex]\displaystyle f(x) = \frac{1-\sqrt{1-4x}}{2x}[/tex]
Step back and multiply both sides of the binomial series identity by x, then integrate. This yields
[tex]\displaystyle \int \frac x{\sqrt{1-4x}} \, dx = \int \sum_{n=0}^\infty \binom{2n}n x^{n+1} \, dx[/tex]
[tex]\displaystyle -\frac1{12} \sqrt{1-4x} (1 + 2x) = C_2 + C_1 x + \sum_{n=0}^\infty \binom{2n}n \frac{x^{n+2}}{n+2}[/tex]
Taking x = 0 again points to C₂ = -1/12. Hence
[tex]\displaystyle g(x) = \frac{1 - \sqrt{1-4x}(1+2x)}{12x^2}[/tex]
Then the value of the sum we want is
[tex]\displaystyle \frac{13}8 - \frac1{64} \left(3g\left(-\frac1{16}\right) - f\left(\frac1{16}\right)\right) = \frac{1+\sqrt5}2 = \boxed{\phi}[/tex]

Find the first term of a G.P. whose fifth term is 243 and the
common ratio 3.
Answer:
first term = 3
Step-by-step explanation:
The n th term of a GP is
[tex]a_{n}[/tex] = a₁[tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here r = 3 and a₅ = 243 , thus
a₁ × [tex]3^{4}[/tex] = 243
a₁ × 81 = 243 ( divide both sides by 81 )
a₁ = 3

How to solve 18 - 1 and 7/16 - 7/12 NOTE: Answer has to stay in fraction form.. The answer should be 15 and 47/48, but when I work it out I am not getting this answer. I do understand how they got 48 for denominator..
7/16 - 7/12 ?
common multiple of 16 and 12 = 48 ((3x16 and 12x4)
7/16 - 7/12 = (7x3) / (16x3) - (7x4) / (12x4) = 21/48 - 28/48 = - 7/48
The difference of two supplemtary angles is 58 degrees. Find the measures of the angles
Answer:
The measure of the angles are 61° and 119°
Step-by-step explanation:
Let the first angle = x°
let the second angle = y°
The sum of two supplementary angles = 180°
x° + y° = 180° ----- equation (1)
based on the given question; "the difference of two supplementary angles is 58 degrees."
x° - y° = 58° ------- equation (2)
from equation (2), x° = 58° + y°
Substitute the value of x into equation (1)
(58° + y°) + y° = 180°
58 + 2y = 180
2y = 180 -58
2y = 122
y = 122 / 2
y = 61°
The second angle is given by;
x° = 58° + y°
x = 58° + 61°
x = 119°
Thus, the measure of the angles are 61° and 119°

Which of the following cosine functions has a period of 3Pi
Answer:
C
Step-by-step explanation:
Hello!
In the equation y=a cos bx, we can learn alot about the cosine graph.
a is the amplitude, or how 'long' the cosine graph is.
b is the period, which is how 'wide' one cycle of a cosine period can be. The higher the period, the wider the cycle is.
In this equation, we are focused on finding the period; so any choices that contain amplitude is not a correct answer choice for this problem, which leaves out B and C.
To find the period, we can plug b into [tex]\frac{2\pi }{b}[/tex] , which in a way converts the b value to a period.
For B) y= cos3x
[tex]\frac{2\pi }{3}[/tex]= it does not equal 3 [tex]\pi[/tex]
For C) y=cos [tex]\frac{2}{3}[/tex]x
[tex]\frac{2\pi }{\frac{2}{3}}[/tex]= equals 3 [tex]\pi[/tex] when simplified
Since C equals 3 [tex]\pi[/tex] as a period, C is the only logical answer.

5x+3x=8x
2y+4y=6y
=8x+6y
b)6x-2x+8y-6y

8y-6y=2y
=4x+2y
Answer:
a) x = -0.75y
b) x = -0.5y
Step-by-step explanation:
Simplifying
5x + 3x + 2y + 4y = 0
Combine like terms: 5x + 3x = 8x
8x + 2y + 4y = 0
Combine like terms: 2y + 4y = 6y
8x + 6y = 0
Solving
8x + 6y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6y' to each side of the equation.
8x + 6y + -6y = 0 + -6y
Combine like terms: 6y + -6y = 0
8x + 0 = 0 + -6y
8x = 0 + -6y
Remove the zero:
8x = -6y
Divide each side by '8'.
x = -0.75y
Simplifying
x = -0.75y
Simplifying
6x + -2x + 8y + -6y = 0
Combine like terms: 6x + -2x = 4x
4x + 8y + -6y = 0
Combine like terms: 8y + -6y = 2y
4x + 2y = 0
Solving
4x + 2y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
4x + 2y + -2y = 0 + -2y
Combine like terms: 2y + -2y = 0
4x + 0 = 0 + -2y
4x = 0 + -2y
Remove the zero:
4x = -2y
Divide each side by '4'.
x = -0.5y
Simplifying
x = -0.5y
