Answer:
144.44
Step-by-step explanation:
C = 2 x π x r . C = 2 x 3.14 x 23 = 144.44
Answer:
x = 2
Step-by-step explanation:
1. f(x) basically means y. So f(x) = 3 translates to y=3.
2. At y=3, you can see it meets at x=2.
Answer:
It's like solving a quadratic, but in reverse, and in this case you'll arrive at x2+x−12=0
Explanation:
We're going to go "backwards" with this problem - normally we're asked to take a quadratic equation and find the roots. So we'll do what we normally do, but in reverse:
Let's start with the roots:
x=3, x=−4
So let's move the constants over with the x terms to have equations equal to 0:
x−3=0, x+4=0
Now we can set up the equation, as:
(x−3)(x+4)=0
We can now distribute out the 2 quantities:
x2+x−12=0
Answer:
0.3 L
Step-by-step explanation:
3 L / 10 students = 3/10 = 0.3 Liters per student
Part A :
So the two sides are equivalent,

Solve for x and get 3.
~~
Answer : x = 3
~~
Part B :
To find JM, simply substitute x for 3 and solve,
