Step-by-step explanation:
A quadrilateral is a closed figure with four sides and four vertices. The vertex is a point where line segments meet. The points where the sides of a quadrilateral meet are called the vertices (which is the plural form of "vertex"). The prefix “quad” means four. You can always remember that a quadrilateral is a four sided figure because of this prefix.
Answer:
a = -⅓
b = 3
Step-by-step explanation:
-3a + b = 4
3a + b = 2
b = 4 + 3a = 2 - 3a
6a = -2
a = -2/6
a = - ⅓
-> b = 4 + 3(-⅓)
b = 4 - 1
b = 3
Answer:
(a) fave = 8
(b) c = 64/9
(c) c ≈ 7.111
Step-by-step explanation:
(a) The average value of the function is its integral over the interval, divided by the width of the interval.

__
(b) We want ...
f(c) = 8
3√c = 8 . . . . . use f(c)
√c = 8/3 . . . . . divide by 3
c = (8/3)² . . . . square
c = 64/9
__
(c) c ≈ 7.111

Step-by-step explanation:
Given the decimal number

Rewrite as

∵ 0.05 = 5/100



Given the decimal number
12.346
Rewrite as

∵ 0.346 = 346/1000 = 173/500

Given the decimal number
7.5
Rewrite as

∵ 0.5 = 1/2
