Answer:

$t= 462.82\ days$

Step-by-step explanation:

<u>Exponential Growth </u>

When the number of observed elements grows as the previous value multiplied by a constant ratio, we have exponential growth. The formula to model such situations is

$\displaystyle f(x) = f_o(1 + r)^t$

Where $f_o$ is the initial value of f, 1 + r is the constant ratio, and t is the time expressed in half days (12 hours)

The initial value is 100 Instant followers, thus:

$\displaystyle f(x) = 100(1.01)^t$

We need to know when the number of followers will reach 1,000,000. Setting up the equation

$\displaystyle 100(1.01)^t=1,000,000$

Simplifying by 100

$\displaystyle (1.01)^t=10,000$

Taking logarithms

$\displaystyle t\ log(1.01)=log\ 10,000$

$\displaystyle t\ log(1.01)=4$

Solving for t

$\displaystyle t=\frac{4}{log(1.01)}=925.63$ periods of 12 hrs

$t= 462.82\ days$

M=p/n+4 make n the subject

Kipish [7]

Answer:

$n = \frac {p - 4m}{m}$

Step-by-step explanation:

Given the algebraic expression;

$m = \frac {p}{n + 4}$

To make n the subject of formula.

Cross-multiplying, we have;

$m*(n+4) = p$

$mn + 4m = p$

Rearranging the equation, we have;

$mn = p - 4m$

$n = \frac {p - 4m}{m}$

A cylinder can hold 450 inches of water. How many cubic inches of water can a cone that has a congruent base and equal height to

Paladinen [302]

Answer:

150 cubic inches of water

Step-by-step explanation:

volume of a cylinder = πr²h

Volume of a cone 1/3(πr²h)

π = 22/7

r = radius

volume of a cone = $\frac{1}{3}$ x Volume of a cylinder

450 / 3 = 150 in³
