Answer: It's always decreasing/decaying.
Step-by-step explanation: To find if it is increasing or decreasing, graph the exponential problem.
1. Start at the top.
2. Look at the exponent.
- The exponent is -x. Since negative means opposite/down, it goes down.
Therefore, it's always decaying.
The answer is false.
In fact, the diameter would be the longest chord in a circle, since the points of a diameter need to pass through the center of the circle. Whereas a chord, by definition is any line whose ends are in the circle.
Answer:
Yusuf = 37.5
Ajay = 13.5
Step-by-step explanation:
Lets say.. Yusuf = y and ajay = a
y = 24+a (since yusuf is 24 years older than ajay)
5 years before, the sum of their ages was 41 so subtract 5 from y and a and add the two.
(y-5)+(a-5)=41
We already have defined y in terms of a (y =24+a) so we substitute that in for y.
(24+a-5)+(a-5)= 41
24-5 = 19
19+a+a-5=41
a+a = 2a
2a+19-5 = 41
19-5 = 14
2a+14 = 41
subtract 14 from both sides
2a=27
a=13.5
substitute that in y=24+a
y=24+13.5
y=37.5
lets check these answers.
(37.5-5)+(13.5-5)= 41
37.5-5 = 32.5 and 13.5-5= 8.5
32.5+8.5=41??
