$1\ \text{billion}=1\times 10^9$

$1\ \text{million}=1\times 10^6$

Total amount of water left is

$8\ \text{billion ounces}\\ =8\times 10^9\ \text{ounces}\\ =(8\times 10^3)\times 10^6\ \text{ounces}\\ =8000\ \text{million ounces}$

Yearly consumption of water $13\ \text{million ounces}$

t = Years since 2018

The required function is in million ounces which is $V(t)=8000-13t$

1.) Simplify the expression.

miss Akunina [59]

Answer:

$sin ( u +\frac{\pi}{2} ) = cos (u)$

Step-by-step explanation:

Let us use the identity

sin(A+B)= cos(A) sin(B)+cos (B) sin(A) to simplify the given expression

Then

$sin(u + \frac{\pi}{2})= \cos \left(u\right)\sin \left(\frac{\pi }{2}\right)+\cos \left(\frac{\pi }{2}\right)\sin \left(u\right)$ --------------------(1)
