Due to conservation efforts, the gray whale has been removed from the endangered species list. There are now 13,000 in the world

brilliants [131]

Answer:

$P = 13,000(1.11) ^ t$

Step-by-step explanation:

This scenario can be modeled using an exponential growth equation.

The exponential growth equations have the following form:

$P = p (1 + r) ^ t$

Where P is the population in year t

p is the initial population at t = 0

r is the growth rate

t is the time in years.

In this case we know that the current population is 13,000 and that the growth rate is 11%

$p = 13,000\\r = 0.11$

The equation that models this scenario is:

$P = 13,000(1 + 0.11) ^ t$

$P = 13,000(1.11) ^ t$

Can any one solve this math 7A equation

DiKsa [7]

Answer:

12). Length in the actual will be 6.25x12=75 in

13). Length in the model will be 15/12=1.25 ft

14). depth in the actual will be 32x12=384 cm

15). Width in the actual will be 5.4x12=64.8 ft

16). Diameter in the model will be 21/12=1.75 cm

Step-by-step explanation:

Given table show relation between model and actual prototype.

It is given that the actual prototype is scaled by 12 of the model.

I.e. Model x 12 = Actual.

12).

For mattress,

Length in the model is 6.25 in.

Length in the actual will be 6.25x12=75 in

13).

For corvette,

Length in the actual is 15 ft

Length in the model will be 15/12=1.25 ft

14).

For Water tower,

depth in the model is 32 cm in.

depth in the actual will be 32x12=384 cm

15).

For wingspan,

Width in the model is 5.4 ft

Width in the actual will be 5.4x12=64.8 ft

16).

For Football helmet,

Diameter in the actual is 21cm

Diameter in the model will be 21/12=1.75 cm

B is the midpoint of AC. If AB = x + 5 and AC = 3x - 6, find BC.

Bas_tet [7]

Hey there! I'm happy to help!

We see that at AB is halfway across our line. We see that AC is the total line.

So, to find the other half, we have to subtract AB from AC, which will give us the value of BC.

We first will subtract our x values.

3x-x=2x

And then we subtract our numbers.

-6-5=-11

So, BC is 2x-11.

Have a wonderful day and keep on learning! :D
