Divide 237.50 by 25. The answer is $9.50 per hour
Answer:
(5, - 4)
Step-by-step explanation:
Given a quadratic in standard form : ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= -
x² - 10x + 21 ← is in standard form
with a = 1, b = - 10, so
= - = 5
Substitute x = 5 into the quadratic for the corresponding value of y
y = 5² - 10(5) + 21 = 25 - 50 + 21 = - 4
vertex = (5, - 4)
Correct option D) Base of exponential function is greater than 1 , this function will exceed linear function .
<u>Step-by-step explanation:</u>
Here we have , f(x) = 0.25x + 25 and g(x) = 15(1.25)x . We need to tell As x approaches ∞, which function exceeds whom! Let's find out:
This function is a linear function with an equation of straight line , having slope and y-intercept as :
Graph for this function is attached below .
This function is an exponential function in the form of , where b>1 i.e. for rise in value of x there is exponential increase in value of y or , function .Basically Base of this exponential is greater than 1 , which makes it an increasing function ! Graph for this function is attached below .
Now , Comparing both graphs we see that as x approaches ∞ graph of exponential function is much more vertical than linear function . Since , base of exponential function is greater than 1 , this function will exceed linear function .Correct option D)
