I beg someone to answer ive posted this 3 times and im still not sure how to do it Which of the following is the best estimate for the number of seconds which have elapsed since the start of the year 2000?

(note: date was June 2001)

A) 3 X 10⁴
B) 3 x 10⁵
C) 3 x 10⁶
D) 3 X 10⁷
E) 3 X 10⁸

(with working out please)

D) 3 X 10⁷

Step-by-step explanation:

Estimated days:

Best estimate is D) 3 X 10⁷

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

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)
