Which of the following is the solution to the equation 25(z-2 )= 125? A. z= 5.5
B. z = 3.5
D. z = -2.5
E. z = -0.5

The answer is z = 7.

Step-by-step explanation:

1) Divide both sides by 25.

2) Simplify 125/25 to 5.

3) Add 2 to both sides.

4) Simplify 5 + 2 to 7.

Thus, the answer is z = 7.

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
