Answer:
-4.5
Step-by-step explanation:
I added 3.25 and .5=3.75. Then i did 0.25*-6=1.5. -1.5+3.75=2.25. 2.25*2=-4.5
Answer:
Step-by-step explanation: Sine
The correct answer is y=0.45x
Answer:
f(-3) = -2
f(-2.6) = -2
f(0.6) = 2.4
f(4.5) = 8.5
Step-by-step explanation:
(Whole question:
Evaluate the piecewise function for the given values.
Find f(-3), f(-2,6), f(0.6), and f(4.5) for f(x)={ -2 If x ≤ 0 4x. If 0 <x <1. x + 4. If x ≥ 1)
As the piecewise function shows, the function f(x) has the value of -2 for values of x lesser or equal than 0, has the value of 4x if the value of x is between 0 and 1, and has the value of x+4 for values of x greater or equal than 1.
So, for f(-3), the value of x is lesser than 0, so we have that f(-3) = -2
For f(-2.6), the value of x is lesser than 0, so we have that f(-3) = -2
For f(0.6), the value of x is between 0 and 1, so we have that f(0.6) = 4*0.6 = 2.4
For f(4.5), the value of x is greater than 1, so we have that f(4.5) = 4.5 + 4 = 8.5
Answer: 35.36
----------------------------
Work Shown:
N(t) = N0*(1/2)^(t/5730)
N(t) = 200*(1/2)^(t/5730)
N(14325) = 200*(1/2)^(14325/5730)
N(14325) = 200*(1/2)^(2.5)
N(14325) = 200*0.17677669529663
N(14325) = 35.355339059326
N(14325) = 3<span>5.36</span>
