Answer:
15 49-cent stamps
Step-by-step explanation:
We can solve this problem with the equations <em>0.49(x) + 0.21(y) = 9.45 </em>and <em>x - 5 = y</em>. Well, 0.49(15) + 0.21(10) = 9.45, so we know that there are 15 49-cent stamps and 10 21-cent stamps. The question is asking for the number of 49-cent stamps, so we can tell Travis bought 15 49-cent stamps.

Answer:
Only options A and B are correct, i.e. y = sin∅ and y = cos∅.
Step-by-step explanation:
The graphs that oscillate, should be periodic in nature and continuous functions.
We know all trigonometric functions are periodic in nature. But not all trigonometric functions are continuous.
The function is continuous if its values are defined at all angles and it should not be undefined for any particular angle.
We know the following facts:-
tan(90°) = ∞
sec(90°) = ∞
csc(0°) = ∞
cot(0°) = ∞
<u>Only sin and cos don't have values ∞ at any angle.</u> It means only sin and cos are continuous functions.
Hence, only options A and B are correct, i.e. y = sin∅ and y = cos∅.
The monthly rate is $45 for this cellphone plan.
Step-by-step explanation:
Given,
Amount charged for cell phone = $60
Amount paid by Regina for 24 month plan = $1140
Number of months = 24
Let,
m be the monthly rate for cellphone plan
Number of months * Monthly rate + cellphone charges = Amount paid

Dividing both sides by 24

The monthly rate is $45 for this cellphone plan.
