Answer:
23.52 miles
Step-by-step explanation:
Let us find the number of miles that they would have run.
Kana starts at 9:35 a.m. and runs at an average rate of 7 mph.
Let the time she has spent so far be t.
Speed is given as:
s = d / t
where d = distance and t = time
=> d = s * t
Therefore, for Kana:
d = 7 * t = 7t _____________(1)
Ji-Hun starts at 10:00 am (25 minutes after Hannah) and runs at an average rate of 8 mph.
25 minutes = 25/60 hour = 0.42 hour
So, his time (compared to Kana's) is t - 0.42.
therefore, for Ji-Hun:
d = 8 * (t - 0.42)
=> d = 8t - 3.36 ____________(2)
Equating (1) and (2):
7t = 8t - 3.36
=> 8t - 7t = 3.36
t = 3.36 hours
Therefore, let us find d:
d = 7 * 3.36 = 23.52 miles
So, Ji-Hun will catch up to Kana after 23.52 miles.
The right choice is: A <em>whole</em> number constant could have been <em>subtracted</em> from the <em>exponential</em> expression.
Let be an <em>exponential</em> function of the form 
, where 
and 
are <em>real</em> numbers. A <em>horizontal</em> asymptote exists when 
, which occurs for 
.
For this function, the <em>horizontal</em> asymptote is represented by 
and to change the value of the asymptote we must add the <em>parent</em> function by another <em>real</em> number (
), that is to say:
(1)
In this case, we must use 
to obtain an horizontal asymptote of -3. Thus, the right choice is: A <em>whole</em> number constant could have been <em>subtracted</em> from the <em>exponential</em> expression.

Answer:
D
Step-by-step explanation: just trust me
Principal=₹42800
Rate of interest=5% but 2 years so multiply by 2 =5×2=10%
Time=2 years
Simple interest=42800×10×2/100= ₹8560
Amount=42800+8560=Rs51360
The answer is ₹ 51360
Answer:
y = 7/2x + 7
Step-by-step explanation:
0 = 7/2(-2) + b
0 = -7 + b
b = 7
y = 7/2x + 7
