Answer:
The expected number of jobs is given by the function
Step-by-step explanation:
Given that, there were 230,600 jobs available in the field radiology in the year 2014 and the grow at a rate 0.9% each year.
This is a exponential growth.
Exponential grow function:
P(t)= Amount after t years
= The initial amount
r= rate of grow
t = Time in year.
Here P(t)= j(t), = 230,600, r=0.9%=0.009, t=t
The expected number of jobs is given by the function
Insert 4 for x and 2 for y in the equation
6(4) - (2)^2
24 - 4 = 20
Answer:
x < 2
Step-by-step explanation:
add 2 to both sides, and now you have 4x < 8. Now divide both sides by 4, and now you have x < 2
Let's take these one at a time.
A
The A choice is that the y intercept of g(x) < y intercept of f(x). Remember, a y intercept occurs when x = 0
g(x) = 2 * sqrt(x) - 8
g(0) = 2*0 - 8
g(0) = - 8
=======
f(x) = - 4 when x = 0 (you just read it.) - 4 is greater than -8. That's a true statement. Think money. Would you rather be 4 dollars in debt or 8 dollars in debt?
A: True <<<<<< answer for A.
B
y intercept occurs when x = 0 The values of f(x) and g(x) have been found in part A.
Are they equal?
The y intercept of g(x) = g(0) = 2*sqrt(0) - 8 = - 8
The y intercept of f(x) = f(x) = - 4 when x = 0
Conclusion
They are not equal and B is not the answer.
C
The x intercept occurs when y = 0
g(x) = 0
0 = 2*sqrt(x) - 8
8 = 2*sqrt(x)
4 = sqrt(x)
x = 16
======
When f(x) = 0, x = 16.
Conclusion
The x intercepts are both 16. This statement is true.
C: True <<<<<< answer.
D
If the condition is anything but equal, the statement is false. g(x) is not greater then f(x).
D <<<<<< False.
Answer:
A
Step-by-step explanation:
We are given a table with the points [ (-1, 4), (0, 5), (1, 6), (2, 7) ]
We need to find the slope with [ y2-y1/x2-x1 ]
5-4/0-(-1)
1/1
1
The point (0, 5) represents the y-intercept.
y = 1x + 5
y = x + 5
Note that f(x) = y
f(x) = x + 5
Best of Luck!
