Alright so to find the area of a rectangular prism (a book is a rectangular prism) you need to multiply the 3 numbers they give you so you multiply 7, 812, and 2/12. after you multiply all of the numbers you add ^3 to the end because you found the volume, its not a flat shape or a 2D shape.

Step-by-step explanation:

The angle between vectors is given by

$\cos{\theta} = \dfrac{\vec{\textbf{a}}\cdot \vec{\textbf{b}}}{|\vec{\textbf{a}}||\vec{\textbf{b}}|}$

The magnitudes for the vectors are as follows:

$|\vec{\textbf{a}}| = \sqrt{a_x^2 + a_y^2 + a_z^2}$

$\:\:\:\:\:\:\:=\sqrt{(2)^2 +(-5)^2 + (3)^2} = 6.16$

$|\vec{\textbf{b}}| = \sqrt{b_x^2 + b_y^2 + b_z^2}$

$\:\:\:\:\:\:\:= \sqrt{(3)^2 + (1)^2 + (4)^2} = 5.10$

The dot product between the vectors is

$\vec{\textbf{a}}\cdot \vec{\textbf{b}} = (2)(3) + (-5)(1) + (3)(4) = 13$

Therefore, the angle between the two vectors is

$\cos{\theta} = \dfrac{\vec{\textbf{a}}\cdot \vec{\textbf{b}}}{|\vec{\textbf{a}}||\vec{\textbf{b}}|} = \dfrac{13}{(6.16)(5.10)}$

or

$\theta = 65.56°$

(Need 3 answers) An entomologist discovered a new insect species. The population of the insect species can be modeled by P(n) =

Strike441 [17]

Answer:

See below

Step-by-step explanation:

<u>According to the model, the equation is:</u>

P(n) = 3450*bⁿ

Based on the equation, the initial number of insects is 3450

<u>If b = 1.75, daily growth rate is:</u>

1.75 - 1 = 0.75 = 75%

<u>If we get P(4) = 55200, find the value of b:</u>

55200 = 3450*b⁴
b⁴ = 55200/3450
b⁴ = 16
b⁴ = 2⁴
b = 2
