Answer:
2 dollars for each
Step-by-step explanation:
13 - 5 = 8
8 divided by 4 = 2
The first angle is 42 degrees
the second angle is 84 degrees
the third angle is 54 degrees
This is exponential decay which can be expressed as:
y=ab^t, y=final value, a=initial value, b=rate, t=time
In this case a=25000, r=(100-20)/100=0.8 so
y=25000(0.8^t), so in 4.5 years...
y=25000(0.8^4.5)
y≈$9158.93 (to nearest cent)
We know that
1 mile----------------> 1609.34 meters
26 miles---------------> X
X=26*1609.34=41842.84 m
I apply a rule of three to know the time
if 100 m---------------9.96 sec
41842.84 m----------> x
x=41842.84*9.96/100=4167.5468 sec
to get minutes I divide it by 60---------> 4167.5468/60=69.459113 minutes
to get hours I divide it by 60----------> 69.459113/60=1.1576518 hours
1.1576518= 1 hour 9 minutes 27.55 sec
the answer is 1 hour 9 minutes 27.55 sec------->(4167.5468 sec)
Answer:
Vertex = (7,5)
Length of latus rectum = 2 units
Step-by-step explanation:
The vertex form of a parabola is
...(1)
where, (h,k) is vertex and length of latus rectum is .
The given equation is
...(2)
On comparing (1) and (2), we get
So, vertex of parabola is (7,5).
Length of latus rectum is
Therefore, the length of the latus rectum is 2 units.
