y - 800,000(1+3)
y - 800,000(0.97)
y = 800,000(1.03)
y=800,000(1-3)
Od

Answers

Answer:

y = 800,000[1.03]

Step-by-step explanation:

Given:

Number of people attend 2012 country fair = 800,000

Attendance increases = 3% per year

Find:

Function represents attendance  after 2012

Computation:

A = P[1+r]ⁿ

Assume;

Number of people attend country fair after 2012 = y

So,

y = 800,000[1+3%]¹

y = 800,000[1+0.03]

y = 800,000[1.03]

Function represents attendance  after 2012 is y = 800,000[1.03]

Answers

Answer:

About 6.32 hours.

Step-by-step explanation:

P= production

t=# of hours needed

How many hours are needed to reach the production level of 400?

Plug the numbers into the formula given.

400=300+50 ( t-10 squared)

Combine like terms-  400=350 (t-10 squared)

subtract 350 from itself, then do the same to the other side.

400-350=350-350(t=-10 squared)

50= (t-10squared)

50-10= 40 squared

40 squared= about 6.32.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(x−2)=2(x−3)

(3)(x)+(3)(−2)=(2)(x)+(2)(−3)(Distribute)

3x+−6=2x+−6

3x−6=2x−6

Step 2: Subtract 2x from both sides.

3x−6−2x=2x−6−2x

x−6=−6
