Answer:
a(n) = a(1)*(1/4)^(n-1)
Step-by-step explanation:
The first term is a(1) = 6, and the common ratio is r = 1/4.
Then the general formula for this sequence is
a(n) = a(1)*(1/4)^(n-1)
Answer:
15.8 ft
Step-by-step explanation:
The inclined plane, the base of and the shelving unit form the shape of a right angled triangle.
The hypotenuse is the length of the inclined plane, h.
The base of the triangle is 15 ft.
The height of the triangle is 5 ft.
To find the hypotenuse, h, we have to use Pythagoras rule:

where a = height of the triangle
b = base of the triangle
Therefore:

The inclined plane is 15.8 ft long.
A. My best friends, whose name is Laura, is in law school.
You know this because, if you were to take out the part in between the commas, the sentence would still make sense. It just adds additional detail.
Answer:
60° and 30°
Step-by-step explanation:
I'm going to assume you mean complementary angles.
Complementary angles are angles that form 90° or a right angle
From the question, it is saying that
(5x) +(4x-18) = 90
To work out x, solve the equation
9x-18 = 90
9x = 108
x = 12
Therefore the angle of 5x is 5x12 or 60° and the angle of (4x-18) is going to be 4x12-18 = 30°
So if the number is positive then the opposite is negative, vice versa.
opposite of 4 is -4
opposite of -5 is 5
