Based on the information, there were initially 1200 ferns; the monthly percent rate of change is 68% and this situation is modeled by an exponential growth function

<h3>How to complete the information?</h3>

The given parameters from the question are:

P(n) = 1200(1.68)^n

Where

n represent the number of months

An exponential growth function is represented as:

P(n) = a * (1 + r)^n

Where

a represents the initial value

r represents the rate

By comparison, we have

a = 1200

1 + r = 1.68

This gives

r = 0.68 = 68%

Hence, there were initially 1200 ferns; the monthly percent rate of change is 68% and this situation is modeled by an exponential growth function

9x+10y =1 9x-6y=-15 solve using elimination
Nostrana [21]

Answer:

I. x = -1

II. y = 1

Step-by-step explanation:

Given the following algebraic expressions;

9x + 10y = 1 .......equation 1

9x - 6y = -15 ......equation 2

To solve using the elimination method, we would subtract eqn 1 from eqn 2.

(9x - 9x) + (-6y - 10y) = (-15 - 1)

0x - 16y = -16

-16y = -16

16y = 16

y = 16/16

y = 1

Next, we would find the value of x;

From eqn 1;

9x + 10y = 1

Substituting the value of y, we have;

9x + 10(1) = 1

9x + 10 = 1

9x = 1 - 10

9x = -9

x = -9/9

x = -1

A rectangle and a chai go have the same area. If their bases are the same lengths, how do their Heights compare? Justify your an
Alika [10]
I think u mean triangle in your question.
Area of rectangle = l × b = height × base = bh
Area of traingle = ½bh'
Area of rectangle = Area of triangle (given)
bh = ½bh'
h' = 2h
It means that the height of the given triangle is double the height of the rectangle.

A toy company is making a miniature model of a dump truck. The steering wheel on the toy car that is 0.6 cm corresponds to the s
pentagon [3]
I used the 55.2 and the 0.6 to find a ratio of 92:1, so for every cm of toy car steering wheel there are 92 cm of real truck steering wheel. so using this ratio i times the 3.5cm of the toy car windshield by the 92, this gave me the answer of 322cm, which theoretically is the answer of this equation. 322cm.

The formula below gives the sum of the degrees, S, of the interior angles of a polygon. If n represents the number of sides, whi
Helga [31]

Answer:

The equation representing the value of <em>n</em> is, n=\frac{S}{180^{\text{o}}}+2.

Step-by-step explanation:

The formula to compute the sum of the degrees, S, of the interior angles of a polygon is:

S=(n-2)\times 180^{\text{o}}

Compute the equation of <em>n</em> as follows:

   S=(n-2)\times 180^{\text{o}}

\frac{S}{180^{\text{o}}}=(n-2)

   n=\frac{S}{180^{\text{o}}}+2

Thus, the equation representing the value of <em>n</em> is, n=\frac{S}{180^{\text{o}}}+2.
