[6.2x10^7]x[3x10^2]
=1.86x10^10

The hint is in the question. All you do is times the projection in 2030 with 1950 population.

Which ordered pair is the y intercept of y=2x^2+3x-3?
rosijanka [135]

Answer:

I think it's A - (0,-3)

Step-by-step explanation:

 x,y

(0,-3)

y-intercept equation for this problem:

y=2x^{2}+3x-3

Break it down to smaller parts:

2(0)^{2} +3(0) = 0

0 - 3 = -3

Rewriting it in a neater way:

=> y = 2(0)^{2} +3(0) -3\\y=-3

Therefore, answer A / the first choice is correct

How did the graph of f(x) = x^2 and g(x) = 3/4 x^2 relate?
nirvana33 [79]

g(x) = \frac{3}{4} f(x) or g(x) is 3/4 times of f(x) , F(x) and g(x) have common solution or intersecting point in the graph parabola at x=0 i.e. in origin and x = \frac {4}{3}.

<u>Step-by-step explanation:</u>

We have a function f(x) = x^{2} and another function , g(x) = \frac{3}{4} x^{2}. In the graph of y = x^{2} , the point (0, 0) is called the vertex. The vertex is the minimum point in a parabola that opens upward. In a parabola that opens downward, the vertex is the maximum point.

Graphing y = (x - h)2 + k , where h = 0 & k = 0

Function g(x) can be formed with compression in function f(x) by a factor of 3/4 , i.e. g(x) = \frac{3}{4} f(x) or g(x) is 3/4 times of f(x).Domain and range of f(x) and g(x) are same ! Although structure of both functions is same the only difference is g(x) is compressed vertically by a factor 3/4. Both are graph of a parabola with vertex at (0,0). Also, F(x) and g(x) have common solution or intersecting point at x=0 i.e. in origin.
