Calculus

To calculate 4 x 4 over 5, you first multiply 4 by 4 to get 16. Then, you divide 16 by 5 to get the final answer of 3.2.

Well, let's take a moment to look at this equation. If we substitute x = 0 and y = -5 into the equation y - 6x - 5, we get -5 - 6(0) - 5. Simplifying this, we get -5 - 0 - 5, which equals -10. So, unfortunately, (0, -5) does not make the equation true. But don't worry, mistakes are just happy little accidents that help us learn and grow.

Oh, dude, finding a free solution manual for a specific textbook like Calculus by Thomas Finney 9th edition can be like searching for a needle in a haystack. You might have better luck asking your professor or checking out online forums where students share study resources. Remember, just because it's free doesn't mean it's easy to come by!

To solve for y in the equation 5y = 1.25, you need to isolate y by dividing both sides by 5. This gives you y = 1.25 / 5. When you divide 1.25 by 5, you get y = 0.25. Therefore, y is equal to 0.25 in this equation.

The domain x can repeat in a function as long as it represents the same integer throughout the entire function.

The above answer is not true for a number of reasons.

First of all, the domain of a function need not be restricted to integers, as is implied above.

Second, consider f of x, denoted by f(x), which is defined in the following table:

x f(x)

1 2

2 3

1 4

The value x = 1 repeats. In both cases it represents the same integer. However, the corresponding value of f(x) is not the same. The relationship between x and f(x) is one-to-many. Therefore, f(x) is not a function.

To find the factors of the trinomial (3m^2 + 11mn + 6n^2), we need to break it down into two binomials. First, we find two numbers that multiply to the product of the leading coefficient and constant term, which are (3 \times 6 = 18). Then, we look for two numbers that add up to the middle coefficient, which is 11. The factors are ((3m + 2n)(m + 3n)).

Oh, dude, 1.8 billion is like 1,800 million. So, if you're ever in a situation where you need to convert billions to millions, just move that decimal point over a few spots and voila, you've got your answer. It's not rocket science... unless you're a rocket scientist, then it might be.

2t2+8t+5 = 0 The expression in this quadratic equation is not so simple to factorise because 5 is a prime number which has only two factors (itself and one) but we can get a near enough solution by using the quadratic equation formula. Using the quadratic equation formula gives the solution as: t = - 0.7752551286 or t = - 3.224744871

To find the value of n in the equation 100n = 4.5, you would first divide both sides by 100 to isolate the variable n. This would give you n = 4.5 / 100, which simplifies to n = 0.045. Therefore, the value of n that satisfies the equation 100n = 4.5 is 0.045.

4x+3y=-15

2x-3y=-3

Take second equation and multiply the whole with 2 so that when subtracting the two equations we can cancel out x. so it becomes 4x-6y=-6

4x +3y = -15

( - ) 4x -6y = -6

----------------------------------

0x + (+3-(-6))y = -15 - (-6))

9y = -9 .. or y=-1

So take any one equation and find x by substituting y value

2x - 3(-1)= -3

2x +3 = -3

2x = -6

x = -3

So x = -3, y = -1

There are an infinite number of possible answers.

152*1 or 151+1 or 153-1 or 153/1

and then we can try with 2, 3, 4, etc

and then with 0.1, 0.2 etc

and then 1.1, 1.2, 1.3, ... 2.1, 2.2, 2.3, ... 3.1, etc

and then irrational numbers.

Coefficients can be removed when differentiating, i.e. d/dx 2tanx = 2 d/dx tanx

You should know that d/dx tanx = sec2x (either by differentiating sinx/cosx or by just remembering the derivatives of common trig functions, as it will come in handy).

So the answer is 2sec2x

To solve the equation "x + (-6) = 12," you need to isolate the variable x by adding 6 to both sides of the equation. This cancels out the -6 on the left side, leaving you with x = 18. Therefore, the value of x that satisfies the equation is 18.

2x squared can best be describe as some variable being double and then squared.

The signum function is defined as follows:

f(x) = -1 if x < 0

= 0 if x=0

= 1 if x > 0

It is not one-to-one (bijective) as can be easility seen).

f(2)=1

f(3)=1

f(10)=1

and so on.

Without further context or information about the relationship between x and y, it is impossible to determine the value of y when x is 3. The value of y could be anything depending on the equation or function that defines their relationship. In mathematics, x and y are often related through equations or functions, and without that information, we cannot determine the specific value of y when x is 3.

In mathematics, b x b represents the product of a number b multiplied by itself. This operation is also known as squaring a number. For example, if b = 3, then b x b = 3 x 3 = 9. The result of b x b is always equal to b raised to the power of 2, denoted as b^2.

Oh, dude, direct variation is when two variables change in the same way. In this case, 5x + 3 = 8y + 3, so technically they are changing in the same way by adding 3 to both sides. So, yeah, I guess you could say it's a direct variation, but like, who really cares, right?
