A motarcar is running at the rate of 66 km per hour. Each other its wheels makes 500 revolutios per minute. find the radius of t

wolverine [178]

Answer:

simple

Step-by-step explanation:

The radius of the wheel can be solved from its given speed and RPM.

Converting km/h to m/min

speed = 66 km / h = 66000 m / 60 min

speed = 1100 m / min

Converting one revolution to meters

1100 m / min = 500 revolution / min ... (given)

500 revolutions = 1100 m

1 revolution = 2.2 m

Solving for the radius of the wheels in meters

1 revolution = 2.2 m

2 * pi * radius = 2.2 m

radius = 2.2 m / 2 * pi

radius = 1.1 m / pi

radius = 0.3501 m

Which exponential equation is equivalent to this logarithmic equation?

Lubov Fominskaja [6]

Answer:

$\displaystyle B)x = {5}^{9}$

Step-by-step explanation:

we are given a logarithmic equation

$\displaystyle \log_{5}(x) - \log_{5}(25) = 7$

simplify the log:

$\displaystyle \log_{5}(x) -2 = 7$

add 2 to both sides:

$\displaystyle \log_{5}(x) = 9$

remember that,

$\displaystyle \log_{a}(b) = c \iff {a}^{c} = b$

so we obtain:

$\displaystyle x = {5}^{9}$

hence,

our answer is B)
