Answer:

Step-by-step explanation:

You have 3 points and need to find ax2 + bx + c = y. First use (0,2). x is zero, so y = 2 = c. You have c. Now put (-1,0) into the equation. 0 = 1a -b + 2. Rearrange so you get b = a + 2. Now use the other point. a*(-2 squared) + b*(-2) + 2 = 0. Simplify and substitute (a + 2) for b and you will have the answer.

The population for a city is 94,083 and grows continuously at a rate of 5.5% each year. What is the approximate population in 32
Masja [62]

For this case we have the following equation exponentially:

y = A (b) ^ t

Where,

  • <em>A: initial population </em>
  • <em>b: growth rate </em>
  • <em>t: time in years</em>

Then, replacing values ​​for 32 years we have:

y = 94083 (1,055) ^ t\\y = 94083 (1,055) ^ {32}\\y = 521903

Answer:

the approximate population in 32 years is:

y = 521903

I need help with this question i dont know how to do it thanks &lt;3
Sholpan [36]

Answer:

( c+a, b)

Step-by-step explanation:

The length of the horizontal line is c by taking points D and C

( c-0) =c

So the length of line AB must also be c if it is a parallelogram

Let the coordinate of B be (x,y)

(x-a) =c

x = c+a

The height of the parallelogram is b by taking the difference of the y coordinates from A and D

A -D = b-0 = b

This must be the same form B and C

y -0 = b

y = b

The coordinates of B is ( c+a, b)
