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].

Write the point-slope form of the equation for a line that passes through (6, -1) with a slope of 2.
The value of xi is
The value of yı is
The point-slope form of the equation is
9514 1404 393
Answer:
the value of x1 is 6the value of y1 is -1the point-slope equation is: y +1 = 2(x -6)Step-by-step explanation:
Point-slope form is ...
y -y1 = m(x -x1) . . . . . . line with slope m through point (x1, y1)
The given point is (6, -1), so ...
x1 = 6
y1 = -1
The given slope is 2, so ...
m = 2
Substituting these into the point-slope form above gives ...
y -(-1) = 2(x -6)
y +1 = 2(x -6)
Answer:
y+1= 2(x-6)
Step-by-step explanation:
Hi! Before we begin answering the question, we need to recall the formula for Point-Slope Form which is y- yı= m(x-xi), in which m is the slope of the function. With this given information, we just need to plug in the point (6,-1) and the slope 2 into the given function.
This will look like:
y- (-1) = 2 (x-6)
Notice that two negatives will make a positive, so the left side of the equation is the same as y+1.
Therefore, our answer is y+1= 2(x-6) .

Bookers father sells computer and earns a 4.25 commission on every software package he sells. How much commission would he earn on software package that sold for 15,725 round to the nearest cent
Answer:
Commission= $668
Step-by-step explanation:
Giving the following information:
Commission rate= 4.25% = 0.0425
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
Commission= $668
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:

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
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

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:
$120
Step-by-step explanation:
They have raised $780 and need to raise $900.
(Total amount they need to raise) - (total amount they raised) = (how much more they need to collect)

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
