Identify the parent function. 5 --5
a absolute
b reciprocal
c cube root
d square root
Step-by-step explanation:
For an absolute value function, the graph will look like an arrow with a sharp inflection point.
Reciprocal function will tend towards a limit when stretched to infinity.
Cube root and square root functions do not tend towards infinity at x = 0, because it is either 0 or the constant value.
The best answer here is Reciprocal. (B)
Answer:
b reciprocalStep-by-step explanation:
The graphed is the function y = 1/x, it is an odd function and the graph is hyperbola
The function is reciprocal
Correct option is B

Which of the following is the equation of an ellipse centered at (4,-1) having a
horizontal minor axis of length 14 and a major axis of length 20?
Answer:
B for me
Step-by-step explanation:
Yun lang po correct me if iam wrong
The Required equation for the ellipse is given by [tex]\frac{(x-4)^2}{49}+\frac{y+1}{100} = 1[/tex] Option B. is correct
What is an ellipse?Ellipse is cross-section part of a cone structure when cutting it out a horizontal cross-section of a cone.
(x-h)^2/a^2 + (x-k)^2/b^2 = 1
(h,k) = centre of the ellipse.
a, b = semi minor or major axis,
[tex]\frac{(x-4)^2}{49}+\frac{y+1}{100} = 1[/tex]
thus, the required equation of ellipse is given by [tex]\frac{(x-4)^2}{49}+\frac{y+1}{100} = 1[/tex].

Three consecutive integers have a sum of 87. Find the integers.
Answer:
28, 29, 30Step-by-step explanation:
Let the integers be x- 1, x and x +1, then:
x - 1 + x + x + 1 = 873x = 87x = 29The integers are 28, 29, 30
Answer:
Let the numbers be (x-1), x and (x+1)
According to the above problem,
[tex](x - 1) + x + (x + 1) = 87 \\ 3x = 87 \\ \boxed{x = 29}[/tex]

Sales= $15,725
To calculate the commission earned, we need to use the following formula:
Commission= commission rate*sales
Commission= 15,725*0.0425
Commission= 668.3125

if an object has a density of 3.6g/ml and you put it into water, will it sink or float?
Answer:
Sink
Step-by-step explanation:
We need to find if an object with a certain density will float or sink in water.
The object will sink in water.
The density of the object is 3.6 g/mL
The density of water is generally [tex]1000\ \text{kg/m}^3[/tex]
An object which has a density more than the liquid it is in then the object will sink.
Let us convert the density of the object to [tex]\text{kg/m}^3[/tex]
[tex]1\ \text{g}=10^{-3}\ \text{kg}[/tex]
[tex]1\ \text{mL}=10^{-6}\ \text{m}^3[/tex]
[tex]1\ \text{g/mL}=\dfrac{10^{-3}}{10^{-6}}=10^3\ \text{kg/m}^3[/tex]
[tex]3.6\ \text{g/mL}=3.6\times 10^3=3600\ \text{kg/m}^3[/tex]
The density of the object [tex](3600\ \text{kg/m}^3)[/tex] is greater than that of water [tex](1000\ \text{kg/m}^3)[/tex].
Hence, the object will sink.

Answer:
D. 40.0km
Step-by-step explanation:
When rounding to 3 significant figures, we will have to look at the 4th significant figure. If that figure is 1-4, you round the 3rd figure down. If that figure is 5-9, you round the 3rd figure up.
In this case, the 3rd figure is the tenth 9 and the 4th figure is the hundredth 7.
Since 7 is from 5-9, you round the tenth 9 up. This adds one whole to 39, which makes it 40. You also need to keep 3 significant figures so the decimal zeros are significant. Thus, the answer is 40.0km
Kristine and her friends are raising money for charity. They hope to raise $900 to reach their goal. So far, they have $780. How much more do they need to collect in order to reach their goal?
Answer:

On Saturday, a souvenir shop had 125 customers. Sixty-four percent of the customers paid with a credit card. The other customers paid with cash. How many customers paid with cash?
Answer:
45 customers
Step-by-step explanation:
Given
Total number of customers = 125
percent that paid with credit card = 64%
Customers that paid with credit card = 64% * 125
Customers that paid with credit card = 0.64 * 125 = 80
Number of customers that paid with cash = 125 - 80
Number of customers that paid with cash = 45 customers
How many positive four-digit integers have the three digits the same and a different fourth digit (in some order)
Answer:
81 * 4 = 324.
Step-by-step explanation:
There are 81 * 4 = 324 such integers.
There are 9000 four-digit integers from 1000 to 9999. Let’s refer to the digit that occurs three times as the triplet and the digit that occurs once as the singleton.
In the first (most significant) position there are 9 possible values for the singleton, 1 through 9. In each case there are also 9 possible values for the triplet. For example if the singleton was a 1, the triplets could be anything but a 1: 1000, 1222, 1333, …, 1999. So there are 9 * 9 = 81 cases with the singleton in the first position.
A singleton in the second position can have 10 possible values, 0 through 9. If it’s a 0 there are 9 possible values for the triplet: 1011, 2022, 3033, …, 9099. If it’s anything else there are only 8 possible values for the triplet since the triplet cannot be 0: 2122, 3133, 4144, …, 9199. So there are 9 + (8 * 9) = 81 cases with the singleton in the second position.
The third and fourth positions work just like the second. So the grand total is 81 * 4 = 324.
If you plot the 9000 four-digit integers as a 100 x 90 grid of squares and color the integers with three same digits in red, an interesting pattern occurs:

In right-angled ∆ ABC, ∟B=90⁰. ∆ ABC is in the first and second quadrant on the graph paper. The coordinates of the points A and C are (2,5) and (-2,3). How do you find the possible pairs of coordinates of B?
Answer:
The given coordinates of the points A and C of the right triangle ABC are (2, 5) and (-2, 3) respectively
The possible pairs of the coordinates of the point B are found as follows;
1) Draw a horizontal line from the point C to the right and a vertical line down from the point A to get the point B at (2, 3) which is the point of the perpendicular intersection of the two constructed lines above
2) Draw a vertical line from the point C upwards and a horizontal line to the left from the point A to get the point B at (-2, 5) which is the point of the perpendicular intersection of the two newly constructed lines here
