4 0

Answer: 1.  1*f*(x)-(-(x+4)^2-4)=0

STEP

1

:

Equation at the end of step 1

 fx - x2 - 8x - 12  = 0

STEP

2

:

Solving a Single Variable Equation:

2.1     Solve   fx-x2-8x-12  = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2*f*(x)-((x-1)^2)=0

STEP

1

:

1.1     Evaluate :  (x-1)2   =    x2-2x+1

Equation at the end of step

1

:

 2fx - x2 + 2x - 1  = 0

STEP

2

:

Solving a Single Variable Equation:

2.1     Solve   2fx-x2+2x-1  = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

In Which Quadrant is this true
34kurt

Given:

\sin \theta

\tan \theta

To find:

The quadrant in which \theta lie.

Solution:

Quadrant concept:

In Quadrant I, all trigonometric ratios are positive.

In Quadrant II, only \sin\theta and \csc\theta are positive.

In Quadrant III, only \tan\theta and \cot\theta are positive.

In Quadrant IV, only \cos\theta and \sec\theta are positive.

We have,

\sin \theta

\tan \theta

Here, \sin\theta is negative and \tan\theta is also negative. It is possible, if \theta lies in the Quadrant IV.

Therefore, the correct option is D.

Can someone help me understand how to add and subtract negatives and positives?
IgorC [24]
Okay, as you know, adding a positive and a positive gives you a bigger positive number. e.g 21 + 19 = 40.

Subtracting a positive from a positive might give you a negative number or a smaller positive number. e.g 21 - 19 = 2 or 20 - 24 = -4. That's simple, we all learned this! :)


Adding two negatives (e.g -4 + -5) will always give you a negative number. To make it easier, just think of the numbers only (4, 5), add them together, and then just put a negative sign by the answer (e.g 4 + 5 = 9 so put - to make -9).

Subtracting two negatives can be a bit tricky! When we say, for example, -5 - -4, we must turn the negative number that was to the right of the minus ( -4) into a positive number! So now it becomes -5 +4 ! And then you get your answer. (which is -1).


Adding a positive to a negative can give you a positive or a negative answer. It just depends which number is "bigger". E.g -20 + 31. << 31 is the "bigger" number, and it is a positive, so we know that our answer will be positive. E.g -20 + 9. << 20 is the "bigger" number (even though it's a negative but forget about that) and it is negative, so we know that our answer will be negative.

Adding a negative to a positive can give you a negative or a positive answer. Like I said, it depends on which number is "bigger". e.g 20 + -9 . We can just remove the + sign and it now becomes 20 -9, which is easier to understand. 20 is the bigger number, and it is positive, so we get a positive answer. e.g 20 + -30 becomes 20 -30 and -30 is the "bigger" number and it is negative, so we'll get a negative answer.

Subtracting a negative from a positive does the thing I mentioned earlier: e.g 20 - -9. The -9 is right of the minus sign and becomes positive: 20 +9! :)

Subtracting a positive from a negative, like I said, depends on which number is "bigger". e.g -30 - 9 (we know 9 is positive even though we don't show the + sign).  Now, to make it simple, just block out the - sign by the 30 so it becomes 30 - 9. You know what that answer is: 21. But because -30 is "bigger", and it is a negative number,  the answer will be negative so it's -21. E.g -30 - 42 <<  Block out the - sign by the 30, and 42 is the "bigger" number, so the answer will be a positive. Just look at the difference between "bigger" number and the smaller number (without signs) . That'll give your answer. 42 - 30 = 12. 42 was the "bigger" number and a positive, and we looked at the difference. :)

Part 2: Number Properties
Flura [38]

Answer:

Expression 1 equals, 25.

To make the second expression 19, you add parenthesis

The distance in scientific notation would be 5.8* 10^7.

The diameter of a human hair in scientific notation would be 2.5* 10^-3

Columbus, Ohio: 8.23* 10^5

United States 3.19*10^8

319,000,000/823,000 = 387.606318

So, it's about 387 times larger
