Answer:
Differential equation

Solution

Value of constant k=0.327 days^(-1)
The rumor reaches 80% at 8.48 days.
Step-by-step explanation:
We know
y(t): proportion of people that heard the rumor
y'(t)=ky(1-y), rate of spread of the rumor
Differential equation

Solving the differential equation

Initial conditions:

Value of constant k=0.327 days^(-1)
At what time the rumor reaches 80%?

The rumor reaches 80% at 8.48 days.
x ≤ 2.6 would look like this on the number line, the 2.6 part would be shaded in as well and not left open since x is less than OR EQUAL to 2.6

Answer:
Plane SPT and Plane SPV
Step-by-step explanation:
A plane is defined by the set of three points lying on the same (two dimensional) surface.
A plane 'R' has been given in the picture.
Points lying on this plane or surface are S, P, T and V.
Therefore, possible names may be,
SPT, STV, SPV, PTV
From the given options names of the plane R will be,
Plane SPT and Plane SPV,
