Identify the asymptotes of the graph.
x = 2, y = 2
x = –2, y = 2
x = 2, y = –2
x = –2, y = –2
Answer:
A) x = 2, y = 2
Step-by-step explanation:
An asymptote of a curve is a line which the curve gets infinitely close to, but never touches.
From inspection of the graph, we can see there is a horizontal and a vertical asymptote, both indicated by the dashed straight lines.
The horizontal asymptote is y = 2 (blue dashed line)
The vertical asymptote is x = 2 (red dashed line)
Therefore, the asymptotes are: x = 2, y = 2

You deposit $25,000 into a bank that pays % 4 annual interest compounded monthly.
a) What is the account balance after 3 years?
b) When will the balance reach $40,000 ?
Answer
A: $28,000
B: 15 years
Step-by-step explanation:
A: Since $25,000 is deposited in the bank and you earn 4% interest annually over 3 years you would earn 12% interest. 12% of 25,000 is 3,000. The sum of 25,000 and 3,000 is 28,000 having you earn $28,000 over 3 years.
B: Since every year you earn 4% annual interest and you have $25,000 deposited in the bank you have to find what percentage of 25,000 equals 15,000. Since 25,000 isn't exactly easy to find multiply it by 4. That leaves you with 100,000 which we know you don't have in the bank but it will make it easier to find the percentage. You will also have to multiply 15,000 by 4 giving you 60,000. Now divide the 60,000 by 1,000 which equals 60. What's the point of the number 60? Well, that's the percentage it takes. Now divide 60 by the annual interest which is 4 and that gives you 15. 15 is the number of years it will take for the balance to reach $40,000.

The function f(x)f(x) is graphed below. What is true about the graph on the interval from x=-\inftyx=−∞ to x=ax=a?
Answer:
If graph of any function going towards down in a particular interval. Then , function is decreasing in that interval.
From x = -∞ to x = a , function is positive and decreasing.
Here, a graph is attached in the question.
We know that, if graph of any function is going towards down in particular interval. Then function is decreasing in that particular interval.
If graph of any function is going towards up in particular interval. Then function is increasing in that particular interval.
In given graph. it is observed that in interval x = -∞ to x = a , graph of function is above x - axis and graph is going towards down. Therefore, in given interval function is positive and decreasing.

Describe the graph of the function.
y =Square root of
x-1 + 4
Answer: The answer is D. the last option
Step-by-step explanation:
The correct answer is option d) The graph is the radical function, y = √x shifted right 1 unit and up 4 units.
The original function is y = √(x - 1) + 4, which represents a radical function.
This function involves taking the square root of the quantity (x - 1) and then adding 4 to the result.
By shifting the function right 1 unit, we are replacing x with (x - 1). This means that the graph will be shifted horizontally by 1 unit to the right compared to the standard square root function.
By shifting the function up 4 units, we are adding 4 to the output of the square root function.
This means that the graph will be shifted vertically by 4 units compared to the standard square root function.
Therefore, the graph of the function y = √(x - 1) + 4 is the radical function y = √x shifted right 1 unit and up 4 units.

The best basketball player on a college team kept track of the number of baskets she made in her last eight games.
11 15 19 12 11 16 11 17
Calculate the mean, median, range, and midrange of the number of baskets she made in her last eight games.
The set is 11, 15, 19, 12, 11, 16, 11, 17
Mean = 14
Median = 13.5
Range = 8
Midrange = 15
What is a mean?
It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
The set:
11 15 19 12 11 16 11 17
The sum of the set:
= 11 + 15 + 19 + 12 +11 +16 + 11 + 17
= 112
Mean:
= 112 / 8
= 14
Median:
Arrange the set in ascending order.
11, 11, 11, 12, 15, 16, 17, 19
The Median is the mid-value of the set.
Median = (12 + 15) / 2 = 27/2 = 13.5
Range:
Highest value in the set = 19
Lowest value in the set = 11
Range = Highest value - Lowest value
= 19 - 11
= 8
Midrange:
= (Highest value + Lowest value) / 2
= (19 + 11) / 2
= 30/2
= 15
Thus,
If the set is 1, 15, 19, 12, 11, 16, 11, 17.
Mean = 14
Median = 13.5
Range = 8
Midrange = 15

There are 750 toothpicks in a regular-size box. A jumbo-size box is made by doubling the length, width, and height of the regular box. How many toothpicks will the jumbo box hold?
2250 toothpicks
1500 toothpicks
3000 toothpicks
6000 toothpicks
Answer:
The last option: 6,000 toothpicks.
Step-by-step explanation:
The formula I used: (2L) (2W) (2H)
If a jumbo sized box is made by doubling the length, width, and height then each measurment will be doubled so length x2, width x2, height x2 so therefore those added up would be 8. Then just do 8 times the volume. 8 x 750 = 6,000.
