Which are the roots of the quadratic function f(q) = 92

Explain the difference between f(2) and f(x) = 2. Use a verbal explanation and create examples to make it very clear. Please hel

Firlakuza [10]

Let x be a variable, and f(x) a function of that variable.

f(2) is a <em>number </em>; it's the value of the function f(x) when x = 2, assuming that value exists.

f(x) = 2 is a <em>statement </em>; it says there is some value of x for which the function returns a value of 2. Because it's a statement, it can be true or false.

Here's an example:

Define f(x) = sin(x). Then f(2) = sin(2) ≈ 0.909297.

If x is a real number, then the statement sin(x) = 2 is false, because -1 ≤ sin(x) ≤ 1 for all real x.

If we replace 2 with 1, on the other hand, we get

f(1) = sin(1) ≈ 0.84147

and

sin(x) = 1 ==> x = π/2 + 2nπ

where n is any integer. (So we're talking about numbers like π/2, -3π/2, 5π/2, -7π/2, and so on.) We're saying here that any real number x of the above form satisfies the equation and makes the statement true.

The primers you used in lab amplified 145 base pairs that were adjacent, but not included in the repeat. If you used a different

Elanso [62]

If your PCR product size was 172 and there were 130 base pairs next to a 14 base pair repeat, then there are 3 repeats.

Given that the newly used primer amplifies 130 base pairs that are near

(a) 14 base pair and

(b) the size of the pcr product is 172

Size = (number of base pairs * number of repetitions) + Initial/Primer Amplicon Value

172 = (14 * x) + 130

172 -130 = 14x

42 = 14x

3 = x

Therefore, we can say that the PCR product has 3 repeats.

The steps below show the incomplete solution to find the value of x for the equation.

Reil [10]

The answer is 4x=24 because the next step is to add 4 to both sides

Determine the Rate of Change for this equation.

Lesechka [4]

We are given equation of line 12x-4y+5=18.

We need to find the Rate of Change for this equation.

Please note: Rate of Change is the another name for Slope of an equation.

So, we need to find the slope of the given linear equation.

In order to find the slope(Rate of change) of the equation, we need to solve equation for y and make it in slope-intercept form y=mx+b.

We need isolate it for y on left side.

We have

12x-4y+5=18.

5 is added on left side of the equation.

We need to get rid 5 from left side first.

The reverse operation of addition is subtraction. So, we need to subtract 5 from both sides.

Subtracting 5 from both sides of the equation, we get

12x-4y+5-5=18-5

12x -4y = 13.

Now, we can see, we have 12x on both sides.

We need to get rid 12x from left side now.

Subtracting 12x from both sides, we get

12x-12x -4y = 13-12x

-4y = 13-12x.

-4 is in front of y, we can remove that -4 by dividing both side (each term) by -4.

We get

-4y/-4 = 13/-4-12x/-4.

On simplifying this step, we get

y = - 13/4 + 3x

Now, let us write this equation in slope-intercept form y=mx+b

y= 3x -13/4.

If we compare y= 3x -13/4 and y=mx+b, we can see that coefficents of x are m and 3.

Therefore, m=3.

m represents slope of the equation.

And slope is the another name of Rate of Change.

Therefore, Rate of Change of the given equation is 3.

Does anyone know to solve this?

Aloiza [94]

Answer:

Step-by-step explanBecause many objects are not regularly shaped their volume cannot be determined using a volume formula. The volume of these objects can be found by water displacement. A volume of water sufficient to cover the object is placed in a graduated cylinder and the volume read. The object is added to the cylinder and the volume read again. The difference between the two volumes is the volume of the object. This method is demonstrated using the same battery used above.
