Answer:
Associative propertry of addition.
Step-by-step explanation:
The associative property of addition states that:
It states that we can add numbers regardless of the groups. The sum does not change irrespective of how the addends are grouped.
We are given the expression:
It can be written as:
It can also be written as:
Whatever maybe the arrangement of r, h and t, their sum will always be equal. We can regroup them in many ways but the sum remains the same.
Answer:
<h2>SU = 3.5</h2>
Step-by-step explanation:
We have the triangle 30° - 60° - 90°.
Right triangles with 30-60-90 angles will have their ratio of the sides as
1 : √3 : 2 (look at the picture).
We have:
SR : SU : RU = 1 : √3 : 2
Therefore RU = 2SR and SU = SR√3.
We have RU = 4. Substitute:
2SR = 4 <em>divide both sides by 2</em>
SR = 2
SU = 2√3 ≈ 2(1.73) = 3.5

Answer:
<h2>See the explanation.</h2>
Step-by-step explanation:
In one hour, the population has increased from 100 to 570.
The population becomes % of 100.
Hence, according to our observation, we can tell that the population of the bacteria grows up to 570% of previous hour.
(a)
The number of bacteria after t hours can be represented as .
(b)
After 4 hours, the <u>number of bacteria will be</u> .
(c)
The derivative of p(t) is .
At t = 4, the value will be 183723.6268 ≅ 183724.
(d)
<u>The population will be 10,000 that is p(t) = 10000</u>.
