Answer:

63°

Step-by-step explanation:

  • m\angle BKD =\frac{1}{2}(m\widehat {AE} +m\widehat {BD} )

  • \implies m\angle BKD =\frac{1}{2}(86\degree +40\degree)

  • \implies m\angle BKD =\frac{1}{2}(126\degree)

  • \implies m\angle BKD =63\degree

P(x) = x4 − 9x2 − 4x 12? what some roots
arlik [135]
P(x) = x^4 - 9x^2 - 4x + 12
P(1) = 1^4 - 9(1)^2 - 4(1) + 12 = 1 - 9 - 4 + 12 = 0
x = 1 is a root.
By dividing the polynomial by x - 1, gives other roots as 3 and -2

Write an equation for the translation of x^2 + y^2 = 49 by 7 units right and 4 units up
Tatiana [17]

Answer:

(x - 7)² + (y - 4)² = 49

Step-by-step explanation:

Given

Equation: x² + y² = 49

Required:

New Equation when translated 7 units right and 4 units up

Taking it one step at a time.

When the equation is translated 7 units right, this implies a negative unit along the x axis.

The equation becomes

(x - 7)² + y² = 49

When the equation is translated 4 units up, this implies a negative unit along the y axis.

(x - 7)² + (y - 4)² = 49

The expression can be further simplified but it's best left in the form of

(x - 7)² + (y - 4)² = 49

using the giving information to write an equation. let X represent the number described in the exercise.then solve the equation
ANEK [815]
A number is multiplied by 8 and the result is 28.

A number= x.

8(x)= 28

Divide both sides by 8.

28/8= 3.5

x= 3.5 

I hope this helps!
