Answer:

using trigonometric ratio sin, which is

sin\alpha=opp/hyp to mean opposite/ hypotenuse

sin 40°= x/9

multiply both sides of this by 9 to remove the 9 in the side we have x, we will have

sin 40°/9=x

sin° 40 =0.7451

so x= 0.7451/9

which is

x= 0.0827888888

to give it in 3 decimal places, the answer will be 0.083 since 7 is the fourth number and is more than five, we add 1 to the 2 making it 3

Hope this helps, and please mark brainiest

Answer:

<em>Math will take over Ana's brain at 4.4 hours</em>

Step-by-step explanation:

<u>Exponential Grow </u>

The population of the nanobots follows the equation  

p(t) = 5\cdot 2^t

We must find the value of t such that the population of nanobots is 106 or more, that is

5\cdot 2^t\geq 106

We'll solve the equation

5\cdot2^t= 106

Dividing by 5

2^t= 106/5=21.2

Taking logarithms

log(2^t)= log(21.2)

By logarithms property

t\cdot log(2)= log(21.2)

Solving for t

\displaystyle t=\frac{log21.2} {log2}

t=4.4 \ hours

Math will take over Ana's brain at 4.4 hours

Answer:

B. City P is above sea level and City R is below sea level

Step-by-step explanation:

A. City R is negative meaning it is below sea level however City Q is 0 meaning it is at sea level, so this statement is false.

C. Once again, City P is positive meaning it is above sea level but City Q is 0 meaning it is at sea level, so this statement is false.

D. Like before, City P is above sea level and City Q is at sea level not below, so this is, once again, false.
