Plz help what is 2x4+3x5(5x6)+2x6

Answers

Answer 1

Answer: 2x4+3x5(5x6)+2x6 =
2x4+3x5x30+2x6=
8+15x30+12=
8+450+12=
470

Answer 2

Answer: Order of operations:
P parentheses
E exponents
MD multiplication/division
AS addition/subtraction

Start with parentheses
2x4+3x5(5x6)+2x6
2x4+3x5(30)+2x6
The 5 next to the 30 in parentheses means the 5 and 30 have a multiplication sign between them
2x4+3x5x30+2x6

Now exponents - we don't have any, so no worries

Now multiplication and division, in order from left to right
2x4+3x5x30+2x6
8+3x5x30+2x6
8+450+2x6
8+450+12

Now addition and subtraction, in order from left to right
8+450+12
458+12
470

The resquest of the y'+6y=e^4t, y(0)=2

Answers

This is a linear differential equation of first order. Solve this by integrating the coefficient of the y term and then raising e to the integrated coefficient to find the integrating factor, i.e. the integrating factor for this problem is e^(6x).
Multiplying both sides of the equation by the integrating factor:

(y')e^(6x) + 6ye^(6x) = e^(12x)

The left side is the derivative of ye^(6x), hence

d/dx[ye^(6x)] = e^(12x)

Integrating

ye^(6x) = (1/12)e^(12x) + c where c is a constant

y = (1/12)e^(6x) + ce^(-6x)

Use the initial condition y(0)=-8 to find c:

-8 = (1/12) + c
c=-97/12

Hence

y = (1/12)e^(6x) - (97/12)e^(-6x)

An airplane flies six hundred miles to the south; then, after landing and refueling, it flies due north for three hundred miles. What is the airplane's displacement? (Remember, displacement is a vector, so direction needs to be indicated in your answer).

Answers

Displacement =

   (distance between the start-point and the end-point)
in the direction of
   (direction from the start-point to the end-point).

For the entire story, the displacement is

   300 miles south .

If it's going 600 miles S, and 300 miles N, the displacement is 300 miles S

How to find the inverse of the function f(x)=2x-3 ? Please

Answers

$f(x)=2x-3\n\ny=2x-3\n\n-2x=-y-3\ \ \ \ /:(-2)\n\nx=(1)/(2)y+(3)/(2)\n\nf^(-1)(x)=(1)/(2)x+(3)/(2)$

f(x)=2x-3
y=2x-3
x=(y+3)/2

f⁻¹(x) = (x+3) / 2

If 20 coins are tossed, find the probability that they'll all land on tails.

Answers

The probability would be split for this problem cause knowing with 20 coins , you can split that even amount ... here's what I would do..

Michelle has 20 coins , but only half of them land on heads and others on tails

As for a half , halves are always equaling to 1/2 or 50 (%) knowing we have 20 , you can evenly split that number of coins in a equal position

So ask your self .. what is half of 20? hmmm .. oh I got it , its 10! so knowing you have 20 but then later you split into half which is 10 ... meaning and knowing you have a 50% probability of getting the 20 coins hitting onto tails

hope this helps!
