THE ANSWER IS 42,000.
TO GET THIS WE KNOW THAT 1 KILOMETERS IS 10,000.
SO YOU TAKE 4.2 AND MULTIPLY IT BY 10,000. THAT EQUALS 42,000.
Answer:
477.47 revolutions
Step-by-step explanation:
From the information given:
The formula for calculating the circumference = 2π r
Given that the radius of each wheel = 25 centimeter
Then, the circumference = 2 π (25)
= 50π cm
The distance traveled in 5 minutes is as follows:
Given that:
The speed = 45 km/ hour
i.e.
1 hour = 45 km
In an hour, we have 60 minutes
So, 60 minutes = 45 km
1 minute = 45/60 = 0.75 km
To cm;
0.75 km = (0.75 × 1000) m = 750 m
750 m = 750 × 100 = 75,000 cm
∴
The number of revolution in 5 minutes sInce 1 revolution = 50π cm is:
= 75,000 cm/ 50π cm
= 477.47 revolutions in 5 minutes
Answer:
5

The equation of the level curve described above that contains the points (3,5) is -2u/[u + v]²
<h3>What is the explanation for the above result?</h3>
F(x1, y1) = = √[x² + y²]
contains
f(3, 5)
F(3, 5) = √(3² + 5²)
= √34
= 5.83095
g(u,v) = [u-v]/[u+v]
gu = [(1) (u + v) - (u-v) (1)]/(u+v)²
= 2v/(u+v)²
gv = [(-1) (u + v) - (u-v) (1)]/(u+v)²
= -2u/(u + v)²

Full Question:
Find an equation of the level curve of f(x y) = √x² + y² that contains the point (3, 5)
Answer:
$25,695
Step-by-step explanation:
You can calculate the price of the car in 2000 using the formula to calculate the future value:
FV=PV(1+r)^n
FV= future value
PV= Present value: $7,500
i= rate: 5.5%
n= number of years: 2000-1977= 23
FV= 7,500*(1+0.055)^23
FV= 7,500*(1.055)^23
FV= 7,500*3.426
FV= 25,695
According to this, the approximate value of the car at the time of the auction is $25,695.
