Answer: 29.75%
Step-by-step explanation:
X/100 *80.33=23.90
80.33x=2390
X=2390/80.33 = 29.75
Answer:
B' (1, 2 )
Step-by-step explanation:
Since the centre of dilatation is the origin then multiply the coordinates of B by the scale factor.
B (4, 8 ) → B' (4 × 
, 8 × ) → B' (1, 2 )
Answer:
Area= b*h
- 9*5=45km^2
Step-by-step explanation:
Answer:
Option A.Exponential decay, 55% decrease
we have
This is a exponential function of the form
where a is the initial value
b is the base
b=(1+r)
r is the rate of change
In this problem
a=54
b=0.45
so
0.45=1+r
r=0.45-1
r=-0.55
Convert to percentage
r=-55% ------> is negative because is a exponential decay
