Answer:

10,741,021\ people

Step-by-step explanation:

we know that

The equation of a exponential decay function can be written as

y=a(1-r)^x

where

y ---> is the population of Osaka japan

x ---> the number of years since 2000

a ---> is the initial value or y-intercept

r is the rate of change

we have

a=11,013,000\ people

r=0.05\%=0.05/100=0.0005

substitute

y=11,013,000(1-0.0005)^x

y=11,013,000(0.9995)^x

Predict the population in 2050

so

2050-2000=50\ years

For x=50 years

substitute in the equation

y=11,013,000(0.9995)^{50}

y=10,741,021\ people

A regular polygon
olga55 [171]

Answer:

3.6° = ext. angle

Step-by-step explanation:

For the shape to be a regular polygon, all interior angles must be congruent.

We can find every interior angle by using the formula:

\frac{180(n-2)}{n}

\frac{180(100-2)}{100}

\frac{180(98)}{100}

\frac{17640}{100}

176.4 = each int. angle

We also know that int. and ext. angles are supplementary!

180 = 176.4 - x

3.6° = ext. angle

What is an<br> Answer:<br> equation of the line that passes through the points (-2, 7) and (-8, 4)?
Mariana [72]
-2=x1 7=y1 -8=x2 4=y2

Y=Mx+b

Y2-y1 = 4-7 =-3
X2-x1 = -8-(-2) = -6
M (slope) = 3

Use the coordinate (-8, 4)

Y = MX + B = 4 = 3(-8) + b
4 = -24+ B
Add 24 to both sides to keep your equation balanced
B equals 28

Y = 3X + 28

7-3x= 5x+13
step 1 add 3x
7=8x+13
step 2 subteact 13
-6=8x
step 3 divide both sides by two
