Answer:

24 Bricks.

Step-by-step explanation:

We know the radius is 6 feet and that the diameter is twice that.

We also know the radius is 12 'bricks' in length.

If we divide both numbers by 12, we get that 1 'brick' is half a foot.

Since that's the radius and we want the diameter, we multiply the radius by 2 to get the diameter.

This results in 12 feet, or 24 'bricks'.

A population of 249 birds increases at a rate of 16% annually. jewel writes and exponential function of the form f(x)=abc to rep
Ad libitum [116K]

Answer:

a = 249 and b = 1.16

Step-by-step explanation:

Consider the provided information.

The exponential function for growth is:  y=a(1+ r)^x

Here, a is the initial value and r is the rate of change.

It is given that the number of birds is 249.

It means a = 249

The rate is given 16%

r=0.16

Put the value of a and r in the above formula.

y=249(1+0.16)^x

y=249(1.16)^x

Now we will compare it with the exponential function form y=ab^x

Therefore, a = 249 and b = 1.16

Answer:

1) 10mn - 10×m×n

2)15m - 15×m

10×m×n×+15×m

=10mn+15m

factorize

common number(divisor) = 5

5m(2n+3)

5m*2n=10mn
