The U.S. Bureau of the Census predicted that the population of Pennsylvania would be about 12.7 million in 2010 and then would i

ncrease by about 0.24 million per year until 2018. Which of the following models predicts the population, y, of Pennsylvania (in millions) in terms of x, the number of years since 2010. y = 0.24x + 12.7 y = -12.7x + 0.24 y = -0.24x + 12.7 y = 12.7x + 0.24

Answer:

y=0. 24x + 12. 7

Step-by-step explanation:

since you start with 12. 7 and gain .24 each year, you would multiply the years by. 24 and just add the 12. 7 I hope this makes sense. also I love your profile picture :)

If the table shown below represents a function, then which is the possible value for f?
cluponka [151]

Answer:

C 2

Step-by-step explanation:

This is a parabolic function

Notice how we go negative and then positive

y = ax^2 +bx+c

Let x = 0

-5 = a(0) + b(0) +c

c = -5

y = ax^2 + bx -5

Let x = 3

4 = a(3)^2 +b(3) -5

Let x=-3

4 = a(3)^2 -b(3) -5

Add the two equations

4 = a(3)^2 +b(3) -5

4 = a(3)^2 -b(3) -5

----------------------------

8 = 2a (3)^2 - 10

18 = 2 a(9)

18 = 18a

a =1

Solving for b

4 = 1(3)^2 -b(3) -5

4 = 9 -3b -5

4 = 4 -3b

0 = -3b

0 =b

The equation is

y = (x)^2  -5

Letting y = -1

-1 =x^2 -5

Adding 5 to each side

4 = x^2

Taking the square root of each side

±2 = x

x= ±2

Given the choices

30% of number A is the same as 40% of number B. what could A and B ? <br><br>​
Sunny_sXe [5.5K]

9514 1404 393

Answer:

  A = 4, B = 3

Step-by-step explanation:

You require that ...

  0.30 × A = 0.40 × B

Then ...

  B = (3/4)A . . . . . divide by 0.40

Any pair of numbers that satisfies this equation will be possible values of A and B. One such pair is (A, B) = (4, 3).
