Part A
Your problem statement already shows you the conversion.
Bottles purchased: 5×10¹⁰
Bottles recycled: 8.3×10⁹
Part B
The ratio of bottles purchased to bottles recycled is
... (5×10¹⁰)/(8.3×10⁹) = 0.6×10¹ = 6.0
The number of bottles purchased is 6 times the number of bottles recycle.
Time used for the call to Zurich: ($5-$1.25)/$0.25=15 minutes
15minutes+3minutes=18minutes
Time used for the call to London: ($7.25-$1.25)/$0.25=24 minutes
24minutes+3minutes=27minutes
Difference between the two calls:27-18=9minutes
In the terms you used, not unless you want an integer for an answer.
Answer:
This type of transformation is a horizontal stretch.
<em></em>
Step-by-step explanation:
Given


Required
Determine the type of transformation
The first function can be expressed as:

While the second function is:

Solving f(0.5x), we have to substitute 0.5x for x in 

So:
The second function is:

<em>This type of transformation is a horizontal stretch.</em>
<em></em>
<em>i.e. f(x) stretched to g(x)</em>
Answer:
The angle of A is 80°
Step-by-step explanation:
Given that angle A lies on a straight line which is 180°. So in order to find A, you have to substract 100° from 180° :
∠A + 100° = 180°
∠A = 180° - 100°
∠A = 80°
