Step-by-step explanation:
Malik considers the enlargement of the trapezoid. The side with the length 10 cm becomes the side with the length 25 cm, the side with the length 18 cm becomes the side with x cm.
Write a proportion of corresponding sides:
Cross multiply:
so correct option is C,

Answer:
c) 1 2 4 8
Step-by-step explanation:
<u>Explanation </u>:-
<u><em>Geometric sequence</em></u>
The sequence is of the form a , a r , a r² , a r³ ,.......
'a' is the first term
'r' is the common ratio
1 , 1(2) , 1( 2)² , 1( 2 )³ ...... is a geometric sequence
here a = 1
common ratio
<em>The sequence 1 2 4 8 is a geometric sequence</em>
Answer:
A. The number of boxes that can be packed by Ryan and Daniel each increases over time. Daniel's function has a greater rate of
change than Ryan's function indicating that Daniel can pack more boxes per hour.
Step-by-step explanation:
Given
Ryan: 3 boxes per hour
Daniel:
Required
True statement about their functions
First, we calculate Ryan's function.
In 1 hour, he can pack 3 boxes.
In hours, he can pack 3h boxes.
So, the equation is:
So, we have:
---- Ryan
--- Daniel
Both functions represent direct proportional functions.
So, when h increases y also increases.
<em>However, Daniel's function has a greater rate of change because</em><em> implies that he can pack 4 boxes per hour while Ryan can pack 3.</em>
