Answer:
2) 10.01 year
Step-by-step explanation:
1) already answered elsewhere in your posts
2) 9000 = 6500 e^(.0325 * t) where t = years
9000/6500 = e^(.0325*t) take ln (natural log) of both sides
.3254224 = .0325t
t = 10.01 10.01 year
Answer: <u> y = -(1/2)x - 1</u>
Step-by-step explanation:
<u>y=2x+3</u>
<u></u>
This is written in the format of y = mx + b, where m is the slope and b the y-intercept. The slope of this reference line is 2. Perpendicular lines will have a slope that is the negative inverse of the slope of the reference line. That means out new line will have a slope of -(1/2):
y = -(1/2)x + b
We can find b by entering the x and y for the given point (-4,1) and solve for b:
y = -(1/2)x + b
1 = -(1/2)(-4) + b
1 = 2 + b
b = -1
y = -(1/2)x - 1
This equation is perpendicular to y=2x+3 and goes through point (-4,1). See attachment.
Sorry I just need points…$2000
In a function, every input has one and only one output.
if -5 is your input, then 5 is the output
if 8 is your input, then 0 is your output
multiple inputs can lead to the same output, like
-6 as the input can give an output of 7
and also -7 as the input can give an output of 7
however, multiple one input cant not have multiple outputs.
since none of those values share the same x values with different y values, the relation is in fact a function.
the answer should be true
a and c both have √x , so they will both be in brackets multiplied by √x.
b is the only term with √y so it will be outside of the brackets.
So the answer will be:
(a - c)√x + b√y
We can check this by expanding the brackets:
(a - c)√x + b√y
= a√x - c√x + b√y
We can rearrange this to get the same original expression:
a√x - c√x + b√y
= a√x + b√y - c√x
