Answer:

The answer to your question is:

Step-by-step explanation:

Data

                                             x² + 8x = -4y - 8

                                             x² + 8x + 16  = -4y - 8 + 16

                                             x² + 8x + 16  = -4y + 8

                                             (x + 4)² = -4(y - 2)

                                             (x + 4)² = 4(-1)(y - 2)

Vertex = (-4, 2)

p =  1

Focus = (-4, 1)

Axis of symmetry  x = -4

Directrix      y = 3

Nata [24]
Since this is a right triangle, we can just use Pythagorean Theorem to solve for the side SU:

Length of Hypotenuse^2 = Length of First Leg^2 + Length of Second Leg^2
SU^2 = ST^2 + TU^2
SU = sqrt(ST^2 + TU^2)
SU = sqrt(42^2 + 56^2)
SU = sqrt(4900)
SU = 70

Therefore, the answer is is 70 centimeters.

Among the career home run leaders for Major League Baseball, hank aaron has 181 fewer than twice the number of chipper Jones. Ha
adoni [48]

Answer: He has 287 home runs

Step-by-step explanation:

Let's define:

H = home runs of Hank

J = home runs of Jones.

We know that:

H = 2*J - 181

H = 755

Then we can replace the second equation into the first one:

755 = 2*J - 181

(755 - 181)/2 = J

287 = J
