Answer:
35cm
Step-by-step explanation:
Given data
Length= 21cm
Width= 28cm
Diagonal= ???
Applying Pythagoras theorem
D^2= L^2+W^2
D^2= 21^2+28^2
D^2= 441+784
D^2= 1225
D= √1225
D= 35cm
Hence the diagonal is 35cm
5/2×2/3. If that is what you mean
Answer: 24(2y−1)
Step-by-step explanation:
Factor 48y−24
48y−24
=24(2y−1)
Answer:
24(2y−1)
See below for the changes when the exponential function is transformed
<h3>How to determine the effect of a</h3>
The exponential functions are given as:




An exponential function of the above form is represented as:

See attachment for the graph of the four functions.
<u>When a is large</u>
This is represented by 
In this case, the curve of the base form
is vertically stretched and it moves closer to the y-axis
<u>When a is small</u>
This is represented by 
In this case, the curve of the base form
is vertically stretched and it moves away from the x-axis
<u>When a is negative</u>
This is represented by 
In this case, the curve of the base form
is vertically stretched and is reflected across the y-axis.
