Find the quotient of these complex numbers.
stich3 [128]

9514 1404 393

Answer:

  C.  (45+11i)/29

Step-by-step explanation:

Multiply numerator and denominator by the conjugate of the denominator.

  \dfrac{5-7i}{2-5i}=\dfrac{(5-7i)(2+5i)}{(2-5i)(2+5i)}=\dfrac{(5)(2)+(-7i)(5i) +(5)(5i)+(-7i)(2)}{2^2+5^2}\\\\=\dfrac{(10+35)+(24-14)i}{29}=\boxed{\dfrac{45}{29}+\dfrac{11}{29}i}

Hellpp please! ASAPP!!
MArishka [77]

Answer:

m∠z= 58.7

Step-by-step explanation:

Remember, all triangles sum up to 180 degrees.

So, the equation would be: 31.3+90+m∠z= 180.

Step 1- Add to simplify.

(31.3+90)+m∠z= 180

121.3+m∠z= 180

Step 2- Subtract to both sides.

121.3+m∠z= 180

-121.3             -121.3

m∠z= 58.7

Help me find the slope
shusha [124]

Answer:

-3/2

Step-by-step explanation:

Slope is defined as \frac{rise}{run},

So the line goes down 6 instead of rising, making the rise negative: -6

The line goes over 4, making the run: 4

So -6/4 or -3/2

The roots of a quadratic equation are (1,0) and (-5,0). What is the axis of symmetry?
leva [86]

Answer:

Step-by-step explanation:

The axis of symmetry lies exactly halfway between the given x = 1 and x = -5.

The axis of symmetry is x = -2.

The 'halfway' value is also the 'average' of 1 and -5:  -4/2, or -2.

The axis of symmetry is x = -2.
