Answer:
A
Step-by-step explanation:
Domain here is where arrows begin. So, domain of this function is {4,5,6,8,9}.
Answer : A.
Answer:
y = -1/2x + 4
Step-by-step explanation:
First, perpendicular lines’ slopes are negative reciprocals. Since the line slope is 2, the perpendicular line is -1/2.
Now whether or not the line passes thru (2,3) is up to the intercept.
Now to find b or intercept
Use y = mx + b to find b
Y = 3 because it’s y in the point.
M is -1/2
X is -2
3 = -1/2(-2) + b
B = 3 + -1/2(-2)
b = 3 + 1
b = 4
The intercept is 4
Therefore the equation is:
y = -1/2x + 4
The function will show exponential decay if one of the following is true
- the base is less than 1 and the exponent is positive
- the base is greater than 1 and the exponent is negative
The function that meets the requirement for exponential decay is ...
If 7% interest is compounded annually, then the value of the $500
after 'Y' years in the future is
$500 (1.07)^to the 'y' power .
For this exercise, it's $500 (1.07)⁴ = $ <u>655.40</u> .
Answer:
Y =1 is a good answer for this question.
