First, you know that B is the mid point, meaning AB is equal to BC. Therefore, you can set up the equation: x+5=2x-11. Then, you solve for x. Once you are done solving, you should get 16. Hope this helps!

Hi! Actually, the answer is 21. Because x+5 and 2x-11 are equivalent, set them equal to one another in an equation. Solve for x

You can see my steps in the picture i attached for you!!

Then, once you have x, you need to plug it back in to the expression x+5 (AB) to get 21. I hope this helps you!! :))

Write an equation for a parabola in which the set of all points in the plane are equidistant from the focus and line. F(–2, 0);

UNO [17]

The line is called the directrix. Here we have a vertical directrix, so a parabola sideways from usual.

Geometry is best done with squared distances. The squared distance from an arbitrary point (x,y) to the vertical line x=2 is $(x-2)^2.$

We equate that to the squared distance of (x,y) to the focus (-2,0):

$(x-2)^2 = (x - -2)^2 + (y - 0)^2$

$x^2 -4x + 4=x^2 +4x +4 + y^2$

$-8x = y^2$

We could call that done. A more standard form might be

$x =- \dfrac 1 8 \ y^2$

The population of Earth is estimated to be 7.4 billion people, or 7,400,000,000. What is this number in scientific notation?

Nitella [24]

Answer:

7.4 x 10 to the 9th power

Step-by-step explanation:

At the end of numbers, there is a decimal point. when writing in function notation, you bring the point to the left or to the right depending on if it is a negative or a positive number

in this problem, you are dealing with a positive number, so bring the decimal point to the left. count how many numbers it takes to get in between, in this number, 7 and 4. it takes 9 spaces to the left. now the decimal point has been moved, your number goes from 7,400,000,000 to 7.4 x 10 to the 9th power(7.4 x 10^9)
