Note that the side adjacent to angle XYZ is given (6 cm) and that the hypo is also given (15 cm).  Thus, cos XYZ = adj / hyp = 6 cm / 15 cm  = 2/5 = 0.4.

XYZ is then  arc cos 0.4.  Use the arccos function on your calculator to determine XYZ and give XYZ in both degrees and radians.

Write an equation of the line that passes through the points (-1, -2) and (2.4)
Lelu [443]

Answer:

As eq of line passing through 2 points is

y-y1 = (y2-y1)/(x2-x1) ][ x -x1)

where (X1,y1)( x2, y2) denotes points lying on line

substitute (X1 ,y1) by( -1,-2) and (X2,y2) by( 2,4)

y+2 = 6/3 )( x+1)

y+2= 2x +2

y = 2x is required equation

What is the simplified form of the quantity of x plus 7, all over the quantity of 6 − the quantity of x plus 5, all over the qua
vlabodo [156]

For this case we must simplify the following expression:

\frac {\frac {x + 7} {6- (x + 5)}} {x + 3}

We must apply double C:

\frac {(x + 7) (x + 3)} {6- (x + 5)} =

We apply distributive property in the numerator:

\frac {x ^ 2 + 3x + 7x + 21} {6- (x + 5)} =\\\frac {x ^ 2 + 10x + 21} {6- (x + 5)} =

In the denominator we have by law of signs:

- * + = -\\\frac {x ^ 2 + 10x + 21} {6-x-5} =

Different signs are subtracted and the sign of the major is placed:

\frac {x ^ 2 + 10x + 21} {- x + 1}

ANswer:

\frac {x ^ 2 + 10x + 21} {- x + 1}
