Is it possible to add a rational number to an irrational number and get a rational
number?
Answer:
no
Step-by-step explanation:
rational numbers are just like negative and positive. If you add a positive number and a negative number together, you are going to get a negative number, so the answer is no.

(5x)2
a0x2
Answer:[tex]a_0=25[/tex]
Step-by-step explanation:
It is given that, [tex](5x)^2=a_0x^2[/tex]
We need to find the value of [tex]a_0[/tex]
As [tex](5x)^2=a_0x^2[/tex]
Solving LHS
[tex]25x^2=a_0x^2[/tex]
Now comparing the coefficients of [tex]x^2[/tex]
In LHS the coefficient of [tex]x^2[/tex] is 25
In RHS the coefficient of [tex]x^2[/tex] is [tex]a_0[/tex]
It implies that, [tex]a_0=25[/tex]
So, the value of [tex]a_0[/tex] is 25.

Solve the following equations
(a) tydt + (t + 1)dy = 0,
(b) y dy dt + t = 1,
(c) ty0 + y = y 2 , with the initial condition, y(1) = 1 2
Answer:
A) In y = - [ x-In (x+1) ] + c
B) [tex]\frac{y^2}{2} = t - \frac{t^2}{2} + c[/tex]
Step-by-step explanation:
A) tydt + ( t + 1 ) dy = 0
dy/y = - ( [tex]\frac{tdt}{t+1}[/tex] ) we have to integrate both sides of the equation
In y = - [ x- In (x +1) ] + c
B) y dy/dt + t = 1
we can express the equation as :
y dy = ( 1 - t ) dt
when we integrate the equation we have
[tex]\frac{y^2}{2} = t - \frac{t^2}{2} + c[/tex]
a(x+b)=g+3f
solve for x
Answer:
[tex]x = (\frac{g + 3f}{a}) - b[/tex]
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
Note that PEMDAS =
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
& is the order of operation.
First, divide a from both sides:
[tex]a(x + b) = g + 3f[/tex]
[tex]\frac{a(x + b)}{a} = \frac{g + 3f}{a}[/tex]
[tex]x + b = \frac{g + 3f}{a}[/tex]
Next, subtract b from both sides to isolate the variable, x.
[tex]x + b (-b) = \frac{g + 3f}{a} (-b)[/tex]
[tex]x = (\frac{g + 3f}{a}) - b[/tex]
[tex]x = (\frac{g + 3f}{a}) - b[/tex]
Point A is the terminal point on the unit circle associated with real number pi/5. What are the coordinates of this point?
Answer:
In polar coordinates, we represent the points as:
P = (R, θ)
Where R is the radius and θ is the angle (depending on how you want to work, you can use θ in degrees or radians).
Then in this case we know that we are working with the unit circle, whose radius is R = 1.
And the angle is pi/5.
Then our point will be:
P = (1, pi/5).
Now we also could write it in rectangular coordinates, knowing that for a point (R, θ) we have:
x = R*cos(θ)
Y = R*sin(θ)
Then for our point the rectangular coordinates are:
x = 1*cos(pi/5) = 0.81
y = 1*sin(pi/5) = 0.59
Then the point is (0.81, 0.59)

Point C is on line segment \overline{BD} BD . Given CD=x,CD=x, BC=5x-5,BC=5x−5, and BD=2x+7,BD=2x+7, determine the numerical length of \overline{CD}. CD .
Answer:
[tex]CD = 3[/tex]
Step-by-step explanation:
Given
[tex]CD = x[/tex]
[tex]BC = 5x - 5[/tex]
[tex]BD = 2x + 7[/tex]
Required
Determine CD
Since, C is a point on BD, the relationship between the given parameters is;
[tex]BD = BC + CD[/tex]
Substitute the values of BD, BC and CD
[tex]2x + 7 = 5x - 5 + x[/tex]
Collect Like Terms
[tex]2x - 5x - x = -5 - 7[/tex]
[tex]-4x = -12[/tex]
Divide both sides by -4
[tex]\frac{-4x}{-4} = \frac{-12}{-4}[/tex]
[tex]x = 3[/tex]
To determine the length of CD;
Substitute 3 for x in [tex]CD = x[/tex]
Hence;

What are 3 equivalent fractions for 4/8
Answer:
1/2, 3/6, 7/14
Step-by-step explanation:
Each are 1/2 :)
The 3 equivalent fractions of 4/8 = 8/16, 12/24, and 16/32.
What are equivalent fractions?Equivalent fractions are those fractions that are made up of different numerator and denominator but are equal to the same value.
To find the equivalent fractions of 4/8, multiply the numerator and denominator by the same number.
That is , 4/8 ×2 = 8/16
4/8 × 3 = 12/24
4/8 × 4 = 16/32
Therefore, the 3 equivalent fractions of 4/8 = 8/16, 12/24, and 16/32.

Find the equation of the line perpendicular to y=2x-6 that passes through the point (1,5). If possible, write the equation in slope-intercept form.
Answer:
y = - [tex]\frac{1}{2}[/tex] x + [tex]\frac{11}{2}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x - 6 ← is in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex] , thus
y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (1, 5) into the partial equation
5 = - [tex]\frac{1}{2}[/tex] + c ⇒ c = 5 + [tex]\frac{1}{2}[/tex] = [tex]\frac{11}{2}[/tex]
y = - [tex]\frac{1}{2}[/tex] x + [tex]\frac{11}{2}[/tex] ← equation of perpendicular line

imagine you and a friend are trying to rearrange the furniture in your classroom. You push on a desk with a force of 150 N to the right. Your friend pushes on the same desk with a force of 50 N to the left. What is the net force on the desk?
Answer:
100NStep-by-step explanation:
If I push on a desk with a force of 150 N to the right and my friend pushes on the same desk with a force of 50 N to the left, this means that I pushed the desk in the positive x direction and the force I applied is F1 = +150N; my friend pushes the desk in the negative x direction and the applied force will be F2 = -50N.
THe net force will the sum total of both forces acting on the desk.
Net force F = F1+F2
Given F1 = +150N and F2 = -50N
Net force F = +150N+(-50N)
Net force F = +150N-50N
Net force F = +100N
Hence the net force on the desk is 100N
if the radius of the right cylinder is 5 in and the radius of the oblique cylinder is 4 in, they will have the same volume as long as they are the same height.
a. True
b. False
Answer:
False.
Step-by-step explanation:
Recall that the volume of a right cylinder is given by the formula:
[tex]V=\pi r^2h[/tex]
And the volume if a oblique cylinder is likewise also given by the formula:
[tex]V=\pi r^2h[/tex]
From the formulas, therefore, if the heights are equivalent, then the radii must also be equivalent for the two cylinders to have the same volume.

Juan proyecta alquilar un local para hacer funcionar un gimnasio cuando las normas sanitarias lo permitan. El alquiler mensual es de S/2000, ¿a cuanto equivale el impuesto que debe pagar el dueño por alquilar su local?
Answer:
Si posee una propiedad y la alquila a inquilinos, ¿cómo se gravan esos ingresos?
La respuesta es que los ingresos por alquileres se gravan como ingresos ordinarios. Si está en el tramo impositivo marginal del 22% y tiene $ 5,000 en ingresos por alquiler que declarar, pagará $ 1,100.
Sin embargo, hay más en la historia. Los propietarios de propiedades de alquiler pueden reducir sus cargas fiscales de varias formas. De hecho, una propiedad rentable en alquiler podría no mostrar ingresos, o incluso una pérdida, a efectos fiscales.
Si uno de sus inquilin os le extiende un cheque por $ 1,000 por mes para cubrir su alquiler, se trata de ingresos por alquiler.
El impuesto deducido en el que incurre el propietario depende del tramo impositivo marginal del estado del país. Si el tramo impositivo marginal es del 20%, el impuesto será 20/100 x 2000 = 400

Answer:
d ⇒ di^(21-22) = -di, facing right from where it was; order doesn't matter
Step-by-step explanation:
For direction defined as 1, i, -1, -i, a left turn is accomplished by multiplying by i. Then "L" left turns will be multiplication by i^L.
A right turn is equivalent to multiplication by -i, so R right turns will be multiplication by (-i)^R.
We know that turning left and turning right are inverse operations of each other, so we can also write a right turn as multiplication by i^(-1). Then R right turns will be equivalent to multiplication by i^(-R).
We know from the commutative and associative laws of multiplication that the order does not matter. So, L left turns and R right turns will be equivalent to multiplication by ...
(i^L)(i^-R) = i^(L -R)
Hence 21 left turns and 22 right turns is equivalent to a turn of ...
i^(21-22) = i^-1 . . . . one right turn
From an initial facing direction of 'd', the final facing direction after these 43 turns is -di.
