Answer:

xy+y^2+2x+4y+4

Step-by-step explanation:

simplify by multiplying variable in the first parentheses set with the ones in the second parentheses set:

(x+y+2)(y+2)

=(x)(y)+(x)(2)+(y)(y)+(y)(2)+(2)(y)+(2)(2)

=xy+2x+y^2+2y+2y+4

=xy+y^2+2x+4y+4

hope this helps!

Determine how long it will take an object to rotate through 6.9 revolutions at an angular velocity of 3.1 radians per second. Us
gregori [183]

Answer: 13 . 99 seconds

Step-by-step explanation:

The formula to find how long it will take an object to rotate through 6.9 revolutions at an angular velocity is given as :

t = 2π x number of revolutions / angular velocity

Therefore :

t = 2π x 6.9 / 3.1

t = 2 x 3.142 x 6.9 / 3.1

t = 43.3596/3.1

t = 13. 98696774194

to the nearest tenth

t = 13. 99s

Given n//p m<2=50 degrees what is m<7?
Bogdan [553]

Answer: m∠7=130°

Step-by-step explanation:

  If two parallel lines are cut by another line (transversal), each one will have four angles surrounding the intersection.

By definition,  the adjacent angles of each parallel line, are supplementary, this means that they add up 180°.

Then, if m∠2=50°, then  m∠3 is:

m∠3=180-50=130°

By definition, the angles that are in the same relative position are know as corresponding angles and they are congruent.

Therefore:

m∠3=m∠7

m∠7=130°

On top of a hill, a rocket is launched from a distance 80 feet above a lake. The rocket will fall into the lake after its engine
Free_Kalibri [48]
The maximum height is 144 feet.

The maximum height is the y-coordinate of the vertex.  To find the vertex, we first use x = -b/2a.  For our information, that is x=-64/2(-16) = -64/-32 = 2.

Now we substitute this into the equation:
y = -16(2²) + 64(2) + 80 = -64 + 128 + 80 = 144
