pshichka [43]

Answer:

v(t) = s′(t) = −9sin(t)+9cos(t)

a(t) = v′(t) = −9cos(t) −9sin(t)

Explanation:

Given that

s = 9 cos(t) + 9 sin(t), t ≥ 0

Then acceleration and velocity is

v(t) = s′(t) = −9sin(t)+9cos(t)

a(t) = v′(t) = −9cos(t) −9sin(t)

How many atoms of each element are in the chemical formula P205?
Irina-Kira [14]

2 atoms of P (phosphorus) and 5 atoms of O (oxygen)

Explanation:

The chemical formula of a generic compound is written as

A_n B_m

where

A and B are the symbols of the elements contained in the compound

n and m are the number of atoms of each element, A and B respectively

In this problem, the compound given is

P_2 O_5

where:

- P is the symbol of the chemical element phosphorus

- O is the symbol of the chemical element oxygen

We see that the number following P is 2, so there are 2 atoms of phosphorus, while the number following O is 5, so there are 5 atoms of oxygen.
