Velocity=distance/time
Data:distance=10 Km=10 km*(0.621 miles/1 km)=6.21 miles.time=55 minutes
Velocity=6.21 miles/55 minutes=0.11290909... miles/minute≈0.113 miles/ minute
Data: distance=1 mile.velocity=0.113 miles/minute
time=distance /velocitytime=(1 mile) / (0.113 miles/ minute)=8.85668... minutes≈8.86 minutes.
Answer: D 8.86 minutes.
Get all the x terms on one side, and the w on the other.
Add 37x on both sides to get 56x+rx=w.
Use the distributive property backwards to get x(56+r)=w.
Divide by 56+r on both sides to get x=w/(56+r)
Answer:
A) 2 years at 7% interest
Step-by-step explanation:
You have to use the formula to calculate the amount after a certain period of time with compound interest and that formula would be (The formula in the statement appears to be incomplete as it doesn't have the interest rate):
A=P(1+r/n)^nt, where
A= amount after time has passed
P= Principal
r= Rate expressed as a decimal
n= Number of times in a year that interest is compounded
t= Time in years
A) 2 years at 7% interest
A=$9,000*(1+0.07/12)^12*2
A=$9,000*1.1498
A=$10,348.2
B) 3 years at 6% interest
A=$9,000*(1+0.06/12)^12*3
A=$9,000*1.19668
A=$10,770.12
C) 4 years at 5% interest
A=$9,000*(1+0.05/12)^12*4
A=$9,000*1.22
A= $10,980
D) 5 years at 4% interest
A=$9,000*(1+0.04/12)^12*5
A=$9,000*1.2209
A=10,988.96
According to this, the loan term that will have the lowest cost is: A) 2 years at 7% interest because it is the one in which Angel would pay less.
Before we can determine the rectangular coordinate of the point, let's determine first its polar coordinates. For this, we need two things: radius and angle.
For the radius, we see that point R is 4 units away from the center.
For the angle, we see that it is 30° clockwise or 330° counterclockwise. See the illustration below:
Now that we know the radius is 4 units and the angle is 330° counterclockwise, let's now convert this to rectangular coordinates.
Use the formula below:
For x-coordinate, we have:
For the y-coordinate, we have:
Therefore, the rectangular coordinate of the given polar point is (2√3, -2). Option B.
Here we go ~
To get roots of the function, equate it with 0
So, the roots are 3 and -3 ~
