The units of the initial and final rates of speed are;
<u><em>Initial rate of Speed = ft/hr</em></u>
<u><em>Final rate of speed = mi/min</em></u>
- We are told that the conversion factors he used are;
5280 ft/1 mi and 1 hr/60 min
- Now, the meaning of 5280 ft/1 mi denotes that;
5280 ft mile is equivalent to 1 mile
This means that the initial distance <em>unit </em>used was ft while the final one was mile
Also, 1 hr/60 min denotes that;
1 hour is equivalent to 60 minutes.
This means that the initial time units used was hour while the final one was minute.
- In conclusion, since we know the initial time and distance units used, we can say that the initial rate of speed ft/hr while final speed rate was miles/minutes.

(b.a)(x)= b(a(x)) = b (3x+1)
= 3x+1 -4= 3x -3 = 3(x-1)
domain of b(a(x)) is domain of a(x) that is all real numbers
Answer:
2121.8
Step-by-step explanation:
The principal is 2000
Rate is 3%
Time is 2 years
Therefore the amount that will be present in the account after 2 years can be calculated as follows
= 2000 × (1+0.03)^2
= 2000 × 1.03^2
= 2000 × 1.0609
= 2121.8
Answer:
base area=16π in² height=6 in ⇒ base area= πr²
16π²=π(r)²
r=4 in
v=1/3 ×π (4)²×(6)
v=32π in²
-------------
v=1/3 π(12/2)²×5
v=1/3π(31)×5=
v=60π in³
-------------
v=1/3 π×(25×4)=
v=100π/3 in³
