What are the coordinates of the center of a rectangle?
Just find the midpoint of opposite corners Consider the rectangle with sides of length a and b. The length of a diagonal is then sqrt(a2+b2) The two diagonals cross at the midpoint or where the length of the line from one vertex to the center is one half of a diagonal or (0.5)[sqrt(a2+b2)]. 1- Consider you have Point A(XA,YA) corresponding to the upper left coordinate of the rectangle and you have Point B(XB, YB) corresponding to the lower right coordinate of the rectangle, then, coordinates of the center Point C (XC, YC) is calculated: XC = XA + (XB-XA)/2 YC = YA - (YA-XB)/2 2- Consider you have Point A(XA,YA) corresponding to the upper left coordinate of the rectangle and the width (W) and height (H) of the rectangle, then, coordinates of the center Point C (XC, YC) is calculated: XC = XA + (W)/2 YC = YA - (W)/2
Can you predict the maximum or minimum point on a parabola?
A parabola is (mathematically speaking) a quadratic function, which looks like this y = ax2 + bx + c where a, b and c are constants. (If three points on the curve are known, then a, b and c can be found.) The gradient, then, can be found by differentiation: dy/dx = 2ax + b A parabola has one maximal or minimal point, where the gradient is zero. 2ax + b = 0 x = -b/2a Use the original function to find the corresponding value of y: y = a(-b/2a)2 + b(-b/2a) + c = b2/4a - b2/2a + c = c - b2/4a So the coordinates of your turning point are ( -b/2a , c - b2/4a ) This result can also be derived by completing the square.
What is the formula for finding the altitude of a triangle?
actually it's a2+b2=c2 the altitude is a or b and can be found by c2/a2*=b2* * a2 and b2 are interchangeable. by the way this only works with right triangles.
Reduce -8 plus b2 by 5 plus b2?
(-8 + b2) - (5 + b2) = -8 + b2 - 5 - b2 = -13
What is b2-2b plus 3b-6?
The equation (b2 - 2b) + (3b - 6) = b2 + b - 6
Which is the correct way to total cells B2 through B25?
=SUM(B2:B25)
What is the distance between A7 0 and b2 -5?
Dist2 = [7 - 2]2 + [0 - (-5)]2 = 52 + 52 = 2*52So Dist = 5*sqrt(2) = 7.0711

What is the distance from one point to the other?
In a plane with the normal (x,y) coordinates, the usual distance formula is that the distance between (x1,y1) and (x2,y2) is √((x1-x2)2+(y1-y2)2). This can be extended to n dimensions by letting the distance between (a1,a2,a3,...,an) and (b1,b2,b3,...,bn) be √((a1-b1)2+(a2-b2)2+...+(an-bn)2)
Which formula below will add the value of B2 to the value of C3?
The simplest way is as follows: =B2+C3
If no triangles are present but you know the coordinates of two points it is best to use the Distance Formula?
Yes, or if it's classified as a right triangle then, A2 + B2 = C2 True

(-8 + b2) - (5 + b2) = -8 + b2 - 5 - b2 = -13
How do you write an IF statement to calculate tax on excel?
It depends on the nature of the way you are doing it. Sometimes tax calculations can be complicated as there are many things to consider. So to keep it simple, say if your taxable salary is in cell B2 and it is taxed at 10% if it is under 20000 and 20% if it is 20000 or more, the formula, which could not be in cell B2, would be:=IF(B2
How can you use a calculation to decide whether a data point is an outlier in a data set?
The exact definition of which points are considered to be outliers is up to the experimenters. A simple way to define an outlier is by using the lower (LQ) and upper (UQ) quartiles and the interquartile range (IQR); for example: Define two boundaries b1 and b2 at each end of the data: b1 = LQ - 1.5 × IQR and UQ + 1.5 × IQR b2 = LQ - 3 × IQR and UQ + 3 × IQR If a data point occurs between b1 and b2 it can be defined as a mild outlier If a data point occurs beyond b2 it can be defined as an extreme outlier. The multipliers of the IQR for the boundaries, and the number of boundaries, can be adjusted depending upon what definitions are required/make sense.
