Answer:
false
Step-by-step explanation:
Now to solve this problem, all we have to remember is the
formula for calculating the linear speed given the radial speed, that is:
v = r w
where,
v = is the linear velocity or linear speed
r = is the radius of the circular disk = (1 / 2) diameter
= (1/ 2) (2.5 inches) = 1.25 inches
w = is the radial velocity (must be in rad per time) =
7200 rev per minute
Calculating for v:
v = 1.25 inches (7200 rev per minute) (2 π rad / 1 rev)
v = 56,548.67 inches / minute
Converting to miles per hour:
v = 56,548.67 inches / minute (1 mile / 63360 inches) (60
min / hour)
<span>v = 53.55 mile / hour</span>
Answer:
Step-by-step explanation:
4500 times 5% per year for 3 years = (4500*.05)*3 = answer 1
4500 times 5% per year for 4 years = (4500*.05)*4 = answer 2
Answer 2 minus answer 1 = jackpot
Hello :
answer : D
because : x=0 and y = 0 satisfait : 4x-3y = 6x+y
4(0) -3(0) = 6(0) +0
0=0 ...(right )
