<u>Answer</u>
A) 7.3 in.
Explanation
The area of a triangle = 1/2 ×base length × height
In the question given, base length = height = x
Area = 27 in²
1/2 × x × x =27
1/2×x²=27
x² = 54
x = √54
= 7.3485 in²
Answer:
6, 7 or 8 oranges
Step-by-step explanation:
Answer:
y'(t) = k(700,000-y(t)) k>0 is the constant of proportionality
y(0) =0
Step-by-step explanation:
(a.) Formulate a differential equation and initial condition for y(t) = the number of people who have heard the news t days after it has happened.
If we suppose that news spreads through a city of fixed size of 700,000 people at a time rate proportional to the number of people who have not heard the news that means
<em>dy/dt = k(700,000-y(t)) </em>where k is some constant of proportionality.
Since no one has heard the news at first, we have
<em>y(0) = 0 (initial condition)
</em>
We can then state the initial value problem as
y'(t) = k(700,000-y(t))
y(0) =0
