If 15 buses can carry 795 passengers, what is the total number of passengers that can be carried by 18 buses?
Answer:
954 passengers
Step-by-step explanation:
We can use ratios to solve
15 buses 18 buses
-------------- = ---------------
795 passengers x passengers
Using cross products
15 * x = 18 * 795
15x = 14310
Divide each side by 15
15x/15 = 14310 /15
x =954
18 buses can carry 954 passengers
Una empresa embotelladora de gaseosas lanzará su propia bebida "Delicia" de un litro a un costo variable de S/ 2.50 por unidad, los costos fijos son S/ 18,500. Cada unidad tiene un precio de venta de S/ 4.50. Entonces, determine el número de botellas de un litro que deben venderse para que la empresa obtenga utilidades de S/ 30 000.
Por la ecuación de utilidad, necesitamos una producción de 7,667 botellas de un litro de capacidad para obtener un total de utilidades de S/ 30.000.
¿Cómo determinar las utilidades por la venta de bebidas gaseosas?
Las utilidades (U') se obtienen de sustraer los costes de producción (Cp) a las utilidades netas (U). Los costes de producción (Cp) son la suma de costes variables (C') y costes fijos (C). y la utilidades netas proceden de la venta de botellas. En consecuencia, tenemos la siguiente expresión:
U' = U - Cp
U' = U - C' - C
A continuación, desarrollamos y resolvemos la ecuación resultante:
30000 = 4.50 · x - 2.50 · x - 18500
1.50 · x = 11500
x = 7667
Por la ecuación de utilidad, necesitamos una producción de 7,667 botellas de un litro de capacidad para obtener un total de utilidades de S/ 30.000.

Identify a transformation of the function ƒ(x) = x2 by observing the equation of the function g(x) = (x – 6)2.
f(x) moves 6 unit towards right side along X-axis and forms the function g(x).
Given that, the original function is
[tex]f(x)=x^2[/tex]
and now the function is
[tex]g(x) =(x-6)^2[/tex]
When f(x)=0 then we can get by calculating that,
[tex]x^2=0[/tex]
x=0
So, the f(x) function satisfied by point (0,0).
Now when g(x)=0 then by calculating that we get,
[tex](x-6)^2=0[/tex]
x-6 = 0
x = 6
So g(x) function satisfied by (6,0).
In geometrical words we can say that if we transform from f(x) to g(x) then (0,0) tranformed to (6,0).
That suggests that the function moves 6 unit right along X axis, which is towards positive X axis.

5. In 2011, Manitoba progressive income tax rates were 10.8% on the first $31,000, 12.75% on the next $36,000, anc
17.4% on any additional income. If your gross taxable earnings for the year were $85,000, what percentage of your
earnings did you pay in taxes?
Step-by-step explanation:
0 <= income <= 31000 : 10.8%
31000 < income <= 31000+36000 = 67000 : 12.75%
67000 < income < anything above 67000 : 17.4%
the total income is
$85,000
the taxes paid are
10.8% of 31000 = $3348
12.75% of 67000 - 31000 = 12.75% of 36000 = $4590
17.4% of 85000 - 67000 = 17.4% of 18000 = $3132
so, out of $85000 you paid

100% = 85000
1% = 100%/100 = 85000/100 = 850

The domain for f(x) is all real numbers ___ than it equal to 3
The domain of f(x) is all real numbers > than it equal to 3, for f(x) = 3/x + 2 - √(x - 3).
The domain of a function f(x) is the set of all real values of x, for which real f(x) exists.
In the question, we are asked to find the domain of the function f(x) = 3/x + 2 - √(x - 3).
To find the domain of f(x), we need to check the real values of x, for which real f(x) exists.
We check each part of f(x):
For 3/x, every x gives a real value except x = 0.
For 2, every x gives a real value as it is not dependent on x.
For √(x - 3), real values exist when x - 3 ≥ 0, as negative square roots are not real.
Therefore, after assessing each term, we can say that the domain for f(x) is x - 3 ≥ 0, or x ≥ 3.
Therefore, the domain of f(x) is all real numbers > than it equal to 3, for f(x) = 3/x + 2 - √(x - 3).

Let's change this into vertex form

There's nothing particularly tricky about the limits of integration. The upper limit is a telescoping series converging to 2,
[tex]\displaystyle \sum_{n=1}^\infty \frac4{4n^2-1} = 2 \sum_{n=1}^\infty \left(\frac1{2n-1} - \frac1{2n+1}\right) \\\\ ~~~~~~~~ = 2 \left(\left(1-\frac13\right)+\left(\frac13-\frac15\right) + \left(\frac15 - \frac17\right) + \cdots\right)[/tex]
The lower limit reduces to 0 using the Riemann-Liouville definition of the fractional derivative. For [tex]q\in\Bbb Q[/tex], let
[tex]\displaystyle \frac{d^q}{dx^q} f(x) = \frac1{\Gamma(\lceil q\rceil-q)} \frac{d^{\lceil q\rceil}}{dx^{\lceil q\rceil}} \int_a^x (x-t)^{\lceil q\rceil-q-1} f(t) \, dt[/tex]
With [tex]a=0[/tex], [tex]q=\frac12[/tex] and [tex]\lceil q\rceil=1[/tex], it follows that
[tex]\displaystyle \frac{d^{1/2}}{dx^{1/2}} 1 = \frac1{\Gamma\left(\frac12\right)} \frac d{dx} \int_0^x (x-t)^{-1/2} \, dt = \frac1{\sqrt{\pi x}}[/tex]
Let
[tex]\displaystyle I = \int_0^2 \frac{\tan^{-1}\left(\frac{2-x}{1+2x}\right)}{x^2-4x-1} \, dx[/tex]
Observe that
[tex]f(x) = \dfrac{2-x}{1+2x} = f^{-1}(x)[/tex]
is its own inverse, so by substituting [tex]\frac{2-x}{1+2x}\mapsto x[/tex], we get the equivalent integral
[tex]\displaystyle \int_0^2 \frac{\tan^{-1}(x)}{x^2-4x-1} \, dx[/tex]
We have the identity
[tex]\tan^{-1}(x) + \tan^{-1}\left(\dfrac{2-x}{1+2x}\right) = \tan^{-1}(2)[/tex]
so that
[tex]\displaystyle I + I = \int_0^2 \frac{\tan^{-1}\left(\frac{2-x}{1+2x}\right) + \tan^{-1}(x)}{x^2-4x-1} \, dx[/tex]
[tex]\implies \displaystyle I = \frac{\tan^{-1}(2)}2 \int_0^2 \frac{dx}{(x-2)^2-5}[/tex]
The remaining integral is trivial,
[tex]\displaystyle \int_0^2 \frac{dx}{(x-2)^2-5} = \int_{-2}^0 \frac{dx}{x^2-5} \\\\ ~~~~~~~~ = \frac1{2\sqrt5} \int_{-2}^0 \left(\frac1{x-\sqrt5} - \frac1{x+\sqrt5}\right) \, dx \\\\ ~~~~~~~~= -\frac{\ln(2+\sqrt5)}{2\sqrt5} \\\\ ~~~~~~~~ = -\frac1{\sqrt5} \tanh^{-1}\left(\dfrac2{\sqrt5}\right)[/tex]
Then the integral we want is
[tex]I = \displaystyle \int_0^2 \frac{\tan^{-1}\left(\frac{2-x}{1+2x}\right)}{x^2-4x-1} \, dx = \boxed{-\frac1{2\sqrt5} \tan^{-1}(2) \, \tanh^{-1}\left(\dfrac2{\sqrt5}\right)} \approx -0.357395[/tex]

How to find the trigonometric identity 4cos(-5B) sin3B is equivalent to?Since we have 4cos(-5B) sin3B
Using the trigonometric identity
sin(x + y) - sin(x - y) = 2cosxsiny
So, cosxsiny = [sin(x + y) - sin(x - y)]/2
Since we have 4cos(-5B) sin3B, comparing cos(-5B) sin3B with cosxsiny, we have
x = -5B and y = 3B
So, we have cos(-5B)sin3B = [sin(-5B + 3B) - sin(-5B - 3B)]/2
= [sin(-2B) - sin(-8B)]/2
= [-sin(2B) - {-sin(8B)}]/2 [since sin(-2B) = -sin(2B)]
= [-sin(2B) + sin(8B)]/2
= [sin(8B) - sin(2B)]/2
So, 4cos(-5B)sin3B = 4 × [sin(8B) - sin(2B)]/2
= 2[sin(8B) - sin(2B)]
So, the trigonometric identity 4cos(-5B) sin3B is equivalent to 2[sin(8B) - sin(2B)]

The height of the tower, the line of sight and the ground form a right angled trangle
Height of first towerLet
h = height of first tower, d = distance of tower to middle point = L/2 where L = distance between tower and Ф = angle of elevation of tower from midpoint = 45°Using trigonometric ratios, we have that
tanФ = h/d
= h/L/2
= 2h/L
So, h = LtanФ/2
= Ltan45°/2
= L/2 × 1
= L/2
Height of second towerLet
h' = height of first tower, d = distance of tower to middle point = L/2 where L = distance between tower and Ф' = angle of elevation of tower from midpoint = 60°Using trigonometric ratios, we have that
tanФ' = h'/d
= h'/L/2
= 2h'/L
So, h' = LtanФ'/2
= Ltan60°/2
= L/2 × √3
= √3L/2
Ratio of the height of the towersSo, the ratio of the height of the towers is n = h/h'
= L/2 ÷ √3L/2
= 1/√3
= 1/1.732
= 0.577
≅ 0.58
So, the ratio of the height of the towers is 0.58:1

Participants in a darts tournament get 4 points
if they hit the red circle, 1 point if they hit the
blue circle, and no points if they miss both
circles. Each participant has 4 darts. How
many different scores are possible if everyone
gets at least one point?
Using the Fundamental Counting Theorem, it is found that 80 different scores are possible if everyone gets at least one point.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
There are 4 darts, and for each dart 3 possible scores, hence:
[tex]n_1 = n_2 = n_3 = n_4 = 3[/tex]
Hence the number of possible scores, removing the one score with zero points on all four rounds, is:
N = 3 x 3 x 3 x 3 - 1 = 80.

A line passes through the point (-3,4) and has a slope of -5. Find an equation of this line
Answer:
y = -5x - 11
Step-by-step explanation:
We are given that a line passes through the point (-3,4) and also has a slope of -5.
We want to write an equation of this line.
The equation of the line can be written in 3 different ways:
Slope-intercept form, which is written as y=mx+b, where m is the slope and b is the y intercept.Standard form, which is written as ax+by=c, where a, b, and c are free integer coefficients (but a and b cannot be 0, and a cannot be negative). Slope-point form, which is written as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope, and [tex](x_1, y_1)[/tex] is a pointSince the question did not specify, any of these 3 options will be valid, however, the most common way to write the equation of the line is in slope-intercept form, so let's do it that way.
Because we are already given the value of the slope, we can immediately plug that into the equation.
Replace m with -5.
y = -5x + b
Now we need to find b.
As the equation passes through the point (-3, 4), we can use its values to help solve for b.
Substitute -3 as x and 4 as y.
4 = -5(-3) + b
Multiply
4 = 15 + b
Subtract 15 from both sides.
-11 = b
Substitute -11 as b in the equation.
y = -5x - 11
