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].

Each statement describes a transformation of the graph of y= x.
Which statement correctly describes the graph of
y= x - 8?
A. It is the graph of y= x translated 8 units to the left
B. It is the graph of y= x translated 8 units up.
C. It is the graph of y=x translated 8 units down.
D. It is the graph of y=xwhere the slope is decreased by 8.
Answers
Answer:
c
Step-by-step explanation:
its in slope intercept form, or y=mx+b where b is the y intercept, i.e. how far down the line hits the y axis. m would be the slope but we dont need to worry about that for now. since b is the y intercept, -8 would mean 8 units down

The table shows the number of gallons of water, 9.
that a water pump transfers in s seconds. How many
gallons of water are pumped per second? What is an
equation for the gallons of water, g, that the station
can pump in s seconds?
Answers
Answer:
G = 0.75s
Step-by-step explanation:
First find the unit rate: How many gallons of water can be pumped in 1 second. This means you just have to divide by however many seconds it is being pumped. I'm using 12 and 9. 9/12 = 0.75. This means that in 1 second 0.75 or 3/4 of a gallon will be pumped. Therefore:
G = 0.75s

The value of a is 3 while the value of b is 4
Step-by-step explanation:
Here, we want to express the given polynomial in the given form while giving the values of a and b
We can rewrite the polynomial as follows;
x^2 + 6x + 9 + 4
We can factorize the first part;
x^2 + 3x + 3x + 9 + 4
x(x + 3)+ 3(x + 3) + 4
= (x + 3)(x + 3) + 4

Find the value of f(-6).
Answers
Answer:
f(-6) = 5
Step-by-step explanation:
We want to find the value of the graph when x = -6
Go to where x = -6 and the y value is 5
f(-6) = 5
The number inside f(-6) is just x. So, use your finger to find -6 on the x-axis. Then, trace your finger in a vertical line to find where the function crosses where x = -6. This will be f(-6). We can see that this is 5.

An oil-well contractor drills a shaft 7 meters deeper into the ground every 2 hours. Which graph has a slope that best represents this rate?
Answers
Answer:
Graph G
Step-by-step explanation:
The graphs are attached
Given that the oil-well contractor drills a shaft 7 meters deeper into the ground every 2 hours, hence the rate at which the shaft drills = 7 meter / 2 hours = 3.5 meters per hour
Since the drill goes into the ground, hence the rate is negative that is -3.5 meters per secong
The slope (rate of change) of a line (m) is given by:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
a) For graph F, the line passes through the point (0,0) and (10, -20). Hence:
[tex]Slope\ of\ line\ F=\frac{-20-0}{10-0} =-2\ meters\ per\ second[/tex]
b) For graph G, the line passes through the point (0,0) and (10, -70). Hence:
[tex]Slope\ of\ line\ G=\frac{-70-0}{10-0} =-7\ meters\ per\ second[/tex]
c) For graph H, the line passes through the point (0,0) and (10, -35). Hence:
[tex]Slope\ of\ line\ H=\frac{-35-0}{10-0} =-3.5\ meters\ per\ second[/tex]
d) For graph J, the line passes through the point (0,-3.5) and (10, -3.5). Hence:
[tex]Slope\ of\ line\ j=\frac{-3.5-(-3.5)}{10-0} =0\ meters\ per\ second[/tex]
Answer:The answer is H , It is the graph where -10 is right below the 0 on the y.

McKenzie makes and sells quilts at an art fair. The materials for each quilt cos t$30.50. She sells the quilts for $80. If "n" represents the number of quilts she sells, which expression could be used to represent her total profits?
Answers
Answer:
Total profits = 49.50n
Step-by-step explanation:
Cost of each quilt = $30.50
Selling price of each quilt = $80
Profits = selling price - cost price
= $80 - $30.50
= $49.50
Profits = $49.50
If n = number of quilts she sells
which expression could be used to represent her total profits?
Total profits = profits of each quilt × number of quilt sold
= $49.50 × n
= 49.50n
Total profits = 49.50n

A car company builds two versions of one of its models-a sedan and a station wagon. The ratio of sedans to station wagons is 11:2. A freighter begins unloading the cars at a dock. Tom
counts 18 station wagons and then overhears a dock worker call out, "Okay, that's all of the wagons ... bring out the sedans!" How many sedans were on the ship? Write the number only.
Answers
Answer:
Number of sedans on the ship = 99
Step-by-step explanation:
Given that:
Ratio of sedans to station wagons = 11 : 2
Number of station wagons count by Tom = 18
Number of sedans = x
Ratio of sedans to station wagons = x : 18
The relationship is directly proportional;
11 : 2 :: x : 18
Product of mean = Product of extreme
2x = 11*18
2x = 198
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{198}{2}\\x=99[/tex]
Hence,
Number of sedans on the ship = 99

I need help determineing the next number.?!
Answers
Answer:
The next number is -12 ⇒ B
Step-by-step explanation:
Let us solve the question
∵ The pattern is 2,916, -972, 324, -108, 36, ....
→ All the given numbers are divisible by 3 because the sum of
the digits of each number can divide by 3
2+9+1+6 = 18 → multiple of 39+7+2 = 18 → multiple of 33+2+4 = 9 → multiple of 31+0+8 = 9 → multiple of 33+6 = 9 → multiple of 3∵ The pattern has positive and negative numbers
∴ Each next term = the previous term ÷ -3
→ Let us do that to find the missing number
∵ 2916 ÷ -3 = -972
∵ -972 ÷ -3 = 324
∵ 324 ÷ -3 = -108
∵ -108 ÷ -3 = 36
→ Find the next number by divide 36 by -3
∵ 36 ÷ -3 = -12
∴ The next number is -12
