Answer:
1/3
Step-by-step explanation:
The number of people over 40 is 20 + 30 + 35 = 85.
So the probability is 85/255, which reduces to 1/3.
A pentagon with each side at 4 units and a square with each side 5 units.
Ew. Composition of functions. Ok, f(g(x)) is what that fancy notation means. So, you would take g(x) & substitute that into wherever x is in f(x).
So we get something crazy like
f(x)= 4 - (.5x - 2)^2
Now, we foil out the squared quantity:
f(x)= 4 - (.25x^2 - x - x + 4)
Can you believe they call that simplification?
f(x)= 4 - .25x^2 + 2x -4
Almost there...
f(x)= -.25x^2 + 2x
Hope this helps!
Answer:
B Equation 2 has the smaller y intercept
Step-by-step explanation:
Equation 1
y = -3x-2
This is in the form y= mx+b
The y intercept is b = -2
Equation 2
y = 1/2x-3
This is in the form y= mx+b
The y intercept is b = -3
-2 > -3
The smaller number is -3
Divide 138.16 by 3.14. This gives a diameter of 44 meters.
