Answer:
As θ increases, the value of cos θ decreases
Step-by-step explanation:
As as θ increases, the value of cos θ decreases from 1 to -1 in the first two quadrants ( between 0 and 180 degrees). Cos(0) = 1, cos(90) = 0, cos(180) = -1.
On the other hand, as θ increases from 180 to 360 degrees (last two quadrants) the value of cos θ increases from -1 to 1.

Answer:
SA = 1,176 ft².
Step-by-step explanation:
To find the surface area of the triangular prism, we can solve for the rectangular base, both triangular faces, and lateral sides separately.
For the rectangular base: (Use formula l×w)
20 × 18 = 360 ft²
For the triangular faces: (Use formula 1/2(b·h)
1/2(18 × 12) = 108 ft²
Since there are two faces, we need to double the amount.
108 × 2 = 216 ft².
Finally, solve for the lateral sides:
20 × 15 = 300 ft².
There are two sides, so:
300 × 2 = 600 ft².
Add up all of these areas:
600 + 216 + 360 = 1,176 ft²
-243
Step-by-step explanation:
số dương nhân -3 thì đc số âm, số âm nhân với -3 để đc số dương.
vd: 1. -3 = -3 ; -3 .-3= 9 ;..... 81 . -3= -243
The magnitude of the second atom relative to the first = 10⁻¹¹ / 10⁻¹³ = 100
<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more variables or numbers.
The magnitude of the second atom relative to the first = magnitude of second atom / magnitude of first atom
The magnitude of the second atom relative to the first = 10⁻¹¹ / 10⁻¹³ = 100
