if bob is 4 years older than twice his neighbor's age, and the sum of their ages is 67, what is bob's age ?

bob would be 46

Step-by-step explanation:

take 67 subtract 4 to get 63 and divide it by 3 to get 3 groups of 21

add 21 and 21 to get 42+4=46

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)

step-by-step explanation:

b is the correct answer
