Answer:
1 . option b
2. option d
Step-by-step explanation:
1) Diameter = 8cm
Radius = 8/2 = 4cm
2) Diameter = 8cm
Radius = 4cm
Option 2:
is the right answer
Step-by-step explanation:
We have to convert the details given in Plan one to an equation
Let x be the number of visits to the gym
and y be the total cost for plan one
So,
As each visit costs $3, x number of visits will cost 3x
One time fee is $50
So the equation can be written as:

Hence
Option 2:
is the right answer

Answer:
Choice 3
Step-by-step explanation:
Using V = πr^2 h
Choice 1. π2^2x6 = 75.4
Choice 2. π2.5^2x5 = 98.17
Choice 3. π3^2x4 = 113.1
Choice 4. π3.2^2x3 = 96.51
Answer:Second Step
Step-by-step explanation:
On the right side in step two you added -3b-15b, and ended up with -12b. This is incorrect. -3b-15b is actually -18b
You would split out the velocity into x and y components.
X component: 5.6cos(73)= 1.637i
Y component: 5.6sin(73)= 5.355j
Therefore velocity in its component form is 1.637i + 5.355j ft/s
