Exponential decay is given by the equation
F = P(1 - r)^t
0.5 = 1(1 - 0.092)^t
0.5 = (0.908)^t
log 0.5 = log (0.908)^t
log 0.5 = t * log 0.908
t = (log 0.5)/(log 0.908)
t = 7.18
Answer: 7.2 years
10 - 5 = 5

Answer:
A'(-3,0), B'(0,-3) and C'(4,7)
Step-by-step explanation:
We are given that the vertices of triangle are A(0,-3), B(3,0) and C(-7,4).
We have to find the coordinates of the image of triangle under a rotation of 90° clockwise about the origin.
90° clockwise about the origin
Rule:
Using the rule
The coordinates of A'
The coordinates of B'
The coordinates of C'
Hence, the vertices of image of triangle is given by
A'(-3,0), B'(0,-3) and C'(4,7)
Answer:
Step-by-step explanation:
Using the formula for calculating simple interest
SI = principal × rate × time/100
Given
Principal = $8750
Rate = 9.75%
Time = 2years
Substitute
Interest = 8750×9.75×2/100
Interest = 87.59×19.5
Interest = 1,706.25
Hence the finance charge to the nearest whole dollar is $1706
I can't answer your question if you dont give me answer choices! I'm sorry i couldn't help!
