The quadratic equation x2 + mx + q = 0, where m and q are real numbers, has the complex root a + bi.?
Sphinxa [80]
Remember the quadratic formula determinant?
If b^2 -4ac < 0, a complex root exists.

So for this problem, m^2 - 4q is the determinant, and if less than 0, is complex.

So a=-m/2   and b=(1/2)SQRT(m^2 - 4q)

In a scale drawing, a building has a length of 15 cm. The actual length of the building is 37.5 feet. Whats the scale of the dra
Feliz [49]

Answer:

\frac{15}{37.5}\ \frac{cm}{ft}

or

1.31:100

Step-by-step explanation:

we know that

The scale of the drawing is equal to divide the length of a building in the scale drawing by the actual length of a building

so

\frac{15}{37.5}\ \frac{cm}{ft}

That means

15 cm in the drawing represent 37.5 ft in the actual

Remember that

1\ ft=30.48\ cm

Convert 15 cm to ft

divide by 30.48

15\ cm=15/30.48\ ft

substitute

\frac{15}{37.5}\ \frac{cm}{ft}=\frac{(15/30.48)}{37.5}=\frac{0.0131}{1}

or

1.31:100

That means

1.31 units in the drawing represent 100 units in the actual

Will mark as brainliest (must show work)
Sever21 [200]

Answer:

46

Step-by-step explanation:

With those problems if you are not given a picture is good we draw one.

Because an angle bisector forms 2 congruent angles and because is given that < XVY ≅ < YVW  then

m < XVY = m < YVW

      2x+7 = x+15 , subtract x and 7 from both sides to isolate the like terms

      2x-x = 15-7, combine like terms

           x = 8

From the picture and the given we see that

m < XVW = m < XVY + m < YVW

m < XVW = 2x+7 + x+15 , combine like terms

m < XVW = 3x + 22, substitute x for 8

m < XVW = 3*8 + 22

m < XVW = 46

Check our work:

m < XVY =  2x+7  = 2*8 +7 = 16 +7 = 23

m < YVW =  x+15 = 8 +15 = 23

m < XVW = m < XVY + m < YVW = 23+23 =46
