How does the graph of g(x)=1/x-5. +2 compare to the graph of the parent function f(x)=1/x
Answers
Answer:
x value of vertical asymptote and y value of horizontal asymptote
Step-by-step explanation:
The graph of 1/x approaches infinity as x approaches 0 (the vertical asymptote)
As x gets either bigger or smaller, 1/x approaches the x-axis (from above on the positive side, from below on the negative side) (the horizontal asymptote)
Consider 1/(x-5) + 2, at what value of x does the graph 'go nuts' ?
When the bottom of the fraction becomes 0, x - 5 becomes 0 when x = 5, so the vertical asymptote of g(x) is at x=5
What value of y does f(x) approach as x gets more positive or more negative - as x gets bigger (as an example), y approaches 0
What y value does g(x) approach as x gets bigger? Well, as x gets big, 1/(x-5) gets small, approaching 0. The smallest 0 + 2 can get is 2, so y=2 is the horizontal asymptote

Avery deposited $1,250 in a new savings account. Determine which amount is closest to the balance of the account at the end of 3 years at 5.5% interest compounded annually if she did not make any further deposit or withdrawal.
Answers
Answer:
$1456.25
Step-by-step explanation:
Given data
P= $1,250
t= 3 years
r=5.5%
The compound interest expression is given as
A= P(1+r)^t
substitute
A= 1250(1+0.055*3)
A= 1250(1+ 0.165)
A= 1250(1.165)
A= 1456.25
Hence the amount after 3 years is $1456.25

Dinorah weighs 30.5 kg. Her dog weighs 6.1 kg. How many times as much does Dinorah weigh as her dog?
Answers
Answer:
5 times
Step-by-step explanation:
Given
[tex]D = 30.5kg[/tex] -- Dinorah's weight
[tex]d = 6.1kg[/tex] --- Her dog's weight
Required
Determine how much she weighs as much as her dog
To do this, we simply divide her weight by her dogs.
[tex]n = \frac{D}{d}[/tex]
[tex]n = \frac{30.5kg}{6.1kg}[/tex]
[tex]n = \frac{30.5}{6.1}[/tex]
[tex]n = 5[/tex]
