Answer:

Step-by-step explanation:

I just solve each of them by multiplying them by .35 until I get to the one that is correct. 40*.35=14

Or you can do a proportion which would be-

14 35

----- = -----

x 100

To solve this, you do 14*100=1400. 1400/35=40.

Hope this helps!

Answer:

50º

Step-by-step explanation:

A triangles angles = 180º

Angle A = 40º

Angle C = 90º (this is a right triangle)

In 2012, the population of a city was 6.27 million. The exponential growth rate was 1.47% per year.

Tcecarenko [31]

Answer:

a) $a(t)= 6.27e^{0.0147*t}$

b) 6.84 million

c) 2028.52

d) 47 years

Step-by-step explanation:

a)Here we know standard exponential growth rate is

$a(t)= ae^{k*t}$

In this put t=0 and a(t)=6.27 million

thus we get a = 6.27 million

now $\frac{da}{dt}=a(t)k$

this is equal to(in 2012)= $\frac{1.47}{100}*=0.0147$

b)Put t = 6

we get

$a(t)= 6.27e^{0.0147*6}$

=6.84 million

c) $8 = 6.27e^{0.0147*t}$

take log both sides

we get 16.52 years

d) $2*6.27=6.27e^{0.0147*t}$

take log both sides we get 47 years to get double the current population.

No.

$\sqrt{45}=3\sqrt{5} \\2\sqrt{20} =2\sqrt5}$

If you add them up you DO NOT GET $5\sqrt{5}.$ According to mathematics, it equals to $7\sqrt{5}$ .
