Given cos (theta)=1, find cot (theta)
jok3333 [9.3K]

First problem:

cos (theta)=1

Using the inverse cosine function, you get theta = 0.

Now we find tan 0 = 0

cot(theta) = 1/tan(theta) = 1/0

Division by zero is undefined, so the answer is d. undefined

Second problem:

cos (theta)=1

Use the inverse cosine function.

theta = 0°

Answer: c. 0°

PilotLPTM [1.2K]

Answer:

Q1

<u>The exponential growth model for frogs:</u>

  • F(x) = 100(1.22)ˣ,

F- number of frogs, x- number of years, 1.22 - growth factor

<u>Calculations</u>:

  • F(5) = 100(1.22)⁵ = 270
  • a) F(10) = 100(1.22)¹⁰ = 730
  • b) F(20) = 100(1.22)²⁰ = 5335

Q2

<u>The exponential growth model for bacteria:</u>

  • B(x) = 10(1.8)ˣ

B- number of bacteria, x- number of hours, 1.8 - growth factor

<u>Calculations:</u>

  • a) B(5) = 10(1.8)⁵ = 189
  • b) B(24) = 10(1.8)²⁴ = 13382588
  • c) B(168) = 10(1.8)¹⁶⁸ = 7.68 * 10⁴³
