Write an equation for a rational function with: Vertical asymptotes at x = -2 and x = -3 x intercepts at x = -4 and x = 4 y intercept at 6
Answer:
[ -9(x^2 - 16)] / [4(x^2 + 5x + 6)] = 0
Step-by-step explanation:
Ok this will be a rational function with denominator (x + 2)(x + 3) - to give the vertical asymptotes.
The numerator will be a(x + 4)(x - 4) to give the x-intercepts . The a is some constant.
As the y intercept is (0,6) we have:
6 = a(0-4)(0+4) / (0+2)(0+3)
6 = -16a / 6
-16a = 36
a = - 36/16 = -9/4.
So our equation is -9(x^2 - 16)/ 4(x^2 + 5x + 6) = 0.

PLEASE HELP! Points A and B split the circle into two arcs. Measure of minor arc is 150°. Point M splits major arc with the ratio 2:5 (point M is closer to point B). Find m∠BAM.
Answer:
30 degrees
Step-by-step explanation:
Answer: Measure of ∠BAM is 30°.
Step-by-step explanation:
As given in the question, points A and B split the circle with center O into two arcs in the attached figure below. Major of the minor arc is 150°. And, the point M splits the major arc in the ratio 2 : 5.
We are to find the measure of ∠BAM.
Since the measure of minor arc AB is 150°, so the measure of major arc AB will be
360° - 150° = 210°.
Also, point M divides the major arc AB in the ratio 2 : 5, so we have
[tex]arc~BM:arc~MA=2:5.[/tex]
Therefore, the measure of ∠BOM is given by
[tex]m\angle BOM=\dfrac{2}{2+5}\times210^\circ=\dfrac{2}{7}\times 210^\circ=60^\circ.[/tex]
We know that
the measure of the angle subtended at the center by an arc is equal to twice the measure of the angle subtended at the circumference by the same arc.
That is, on arc BC, we get
[tex]m\angle BOM=2\times m\angleBAM\\\\\Rightarrow m\angle BAM=\dfrac{m\angle BOM}{2}\\\\\\\Rightarrow m\angle BAM=\dfrac{60^\circ}{2}\\\\\Rightarrow m\angle BAM=30^\circ.[/tex]
Thus, the measure of ∠BAM is 30°.

Answer:
1 3/16
Step-by-step explanation:
5/16 + (7/8= 14/16)
14/16 + 5/16= 19/16
16/16 = 1
3 LEFT OVER
1 3/16
Answer:
He caught 1 3/16 pounds of fish.
Minimum weight = 13/16 pounds.
Step-by-step explanation:
So far he caught 5/16 + 7/8
= 5/16 + 14/16 = 19/16
= 1 3/16 pounds.
Minimum wight of the third fish = 2 - 1 3/16
= 32/16 - 19/16
= 13/16 pounds.

The perimeter of a rectangle is 24 centimeters.Its length is 9 centimeters.Find the width
length of rectangle =9cm
width of rectangle = b
perimeter of rectangle =24cm
perimeter of rectangle =2(l+b)
24=2(9+b)
9+b=12
b=3cm
Using the perimeter formula for a rectangle, the width of the rectangle is calculated to be 3 centimeters.
To find the width of the rectangle when the perimeter is 24 centimeters and the length is 9 centimeters, we can use the formula for the perimeter of a rectangle: P = 2l + 2w, where P is the perimeter, l is the length, and w is the width. From the given information:
P = 24 cm
l = 9 cm
We can set up the equation as follows:
24 = 2(9) + 2w
24 = 18 + 2w
2w = 24 - 18
2w = 6
We then divide both sides by 2 to solve for w:
w = 6 / 2
w = 3 cm
Thus, the width of the rectangle is 3 centimeters.
A stack of 9 different cards are shuffled and spread out face down. If 4 cards are tired face up, how many different 4-card combinations are possible?
Answer:
126.
Step-by-step explanation:
This is the number of combinations of 4 cards from 9 cards:
= 9C4
= 9! / 4! 5!.
A quick way of calculating this is
9*8*7*6
----------- = 9*2*7 = 126 combinations.
4*3*2*1
There are 126 different 4-card combinations possible when selecting 4 cards from a shuffled stack of 9 different cards.
To find out how many different 4-card combinations are possible from a stack of 9 different cards when 4 cards are turned face up, we need to use combinatorial mathematics. The formula needed here is the combination formula, which for selecting r items from a set of n items is given by C(n, r) = n! / (r!(n-r)!), where '!' denotes factorial.
Substituting the given values, we get C(9, 4) = 9! / (4!(9-4)!) = 9! / (4!5!) = (9×8×7×6) / (4×3×2×1) = 3024 / 24 = 126. So, there are 126 different combinations of 4 cards that can be turned face up from a shuffled stack of 9 different cards.

f your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? Why? A. The z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. B. The z score of 1.00 is most preferable because it is 1.00 standard deviation above the mean and would correspond to an above average test score. C. The z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average test score. D. The z score of 0 is most preferable because it corresponds to a test score equal to the mean. E. The z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores.
Answer:
E. The z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores.
Step-by-step explanation:
A z score tells us how many standard deviations away from the mean a given value is.
The higher the z-score, the farther above the mean the value is. Since we are referring to the score on a test, we want the value to be as far above the mean as possible; this means that our best choice out of those given is 2.00, since it is 2 standard deviations above the mean.

Answer:
a) 110,880
b) 8.61x10^37
c) 7.18x10^19
Step-by-step explanation:
To find the amount of options, use the following combination equation.
n!/[r! * (n - r)]
In this equation, n represents the amount of possible options and r represents the amount being chosen at a time. We can now calculate out the answer for each possibility.
a) In this case, n would equal 12 and r would equal 6.
n!/[r! * (n - r)]
12!/[6! * (12 - 6)]
479001600/[720*6]
479001600/4320
110,880
b) In this case, n would equal 36 and r would equal 6
n!/[r! * (n - r)]
36!/[6! * (12 - 6)]
3.72x10^41/[720*6]
3.72x10^41/4320
8.61x10^37
c) For this one, n would equal 24 and r would equal 6. We would also then have to divide the answer at the end by 2.
n!/[r! * (n - r)]
12!/[6! * (12 - 6)]
6.20x10^23/[720*6]
6.20x10^23/4320
1.44x10^20 ÷ 2 = 7.18x10^19
This question deals with calculating combinations of croissants chosen under various conditions, which exemplifies the use of combinations with repetition in mathematics. Solutions depend heavily on the specifics of each part, many of which require customized approaches to account for constraints like minimum selections or caps on certain items.
Explanation:This question involves calculating different combinations of items from a set, which in this context are types of croissants being chosen in various quantities and conditions. Solving these problems requires understanding permutations and combinations, specifically combinations with repetition, as the order in which the croissants are selected does not matter but repeats are allowed.
We utilize the formula for combinations with repetition: C(n+r-1, r), where n is the number of types of items (in this case, croissants) and r is the number of items to choose.
For example, in part a) choosing a dozen croissants from 6 types would involve finding the combination with repetition of these 6 types over 12 selections.
However, specific formulas need to be applied to cater to the unique conditions stated in parts c) through f). Each of these parts imposes different constraints (e.g., minimum numbers of specific items, caps on how many of certain items can be chosen) that complicate the calculation and often require a piecewise approach or the inclusion/exclusion principle to accurately count the number of valid combinations.
Due to the complex and varied nature of each part of this question, and without specific formulas for parts c) through f), a general overview is provided instead of detailed solutions.
Each condition requires a tailored approach that involves breaking down the problem into smaller, manageable parts, and sometimes subtracting the cases that do not meet the given criteria from the total possible combinations.

Which is the distance between parallel lines with the equations 3x-5y=1 and 3x-5y=-3
The distance between the parallel lines 3x - 5y = 1 and 3x - 5y = -3 is 4/√34 units.
Explanation:To find the distance between two parallel lines with equations 3x - 5y = 1 and 3x - 5y = -3, we need to use the formula for distance between two parallel lines in a coordinate plane. This formula is:
Distance = |C2 - C1| / sqrt(A^2 + B^2)
In this case, your A coefficient is 3, the B coefficient is -5, and the constants (C1 and C2) are -1 and 3 respectively (from the given equations). Substituting these values into the formula gives:
Distance = |3 - (-1)| / sqrt(3^2 + (-5)^2)
Distance = 4 / sqrt(9 + 25)
Distance = 4 / sqrt(34)
So, the distance between parallel lines with equations 3x - 5y = 1 and 3x - 5y = -3 is 4/sqrt(34) units.

Final answer:
The distance between the parallel lines described by the equations 3x-5y=1 and 3x-5y=-3 is calculated using a standard formula for the distance between parallel lines, resulting in a distance of 4 / √34.
Explanation:
The distance between two parallel lines can be calculated using a formula once the equations of the lines are in standard form. The equations 3x-5y=1 and 3x-5y=-3 are indeed in standard form and clearly show that the lines are parallel because they have the same coefficients for x and y. To find the distance between these parallel lines, one can use the formula involving the absolute difference of the constants in the equations and the square root of the sum of squares of the coefficients of x and y.
The formula for the distance d between two parallel lines Ax + By + C1 = 0 and Ax + By + C2 = 0 is given by:
d = |C2 - C1| / √(A² + B²)
Applying this to our equations, we have:
A = 3, B = -5, C1 = 1, and C2 = -3.
Thus,
d = |-3 - 1| / √(3² + (-5)²) = 4 / √(9 + 25) = 4 / √34
Distance between parallel lines, standard form, and formula are essential in solving this problem.

A pair of shoes at Nordstrom’s costs $120. The shoes are on sale for 15% off. You have a coupon that allows you take an additional 10% off. How much will the shoes cost?
okay so you multiply .15 by 120 which is 18. then you multiply .10 by 120 which is 12. so you do 120 subtracted by 12 and 18 which the answer is 90
Final answer:
The shoes will cost $91.80 after both discounts have been applied.
Explanation:
To find the cost of the shoes, we need to apply two discounts.
First, we calculate the discount amount of 15% off $120 by multiplying $120 by 0.15, which gives us $18.
Then, we subtract this discount from the original price:
$120 - $18 = $102.
Next, we calculate the additional discount of 10% off $102 by multiplying $102 by 0.10, which gives us $10.20.
We subtract this discount from the discounted price:
$102 - $10.20 = $91.80.
So, the shoes will cost $91.80 after both discounts have been applied.
Please Help!! A septic tank has the shape shown in the figure. How many gallons does it hold? (1 cu ft = 7.48 gallons.) (Round to the nearest gallon)
The overall volume is the sum of the volume of a cylinder of height 5'9" and diameter 3'6", and a sphere of diameter 3'6" (two hemispheres = full sphere).
Volume of the cylinder = (area of the base) x (height) = pi * (diameter/2)^2 * 5.75ft = 3.1415 * (3.5ft/2)^2 * 5.75 ft = 55.32 ft^3
Volume of the sphere = 4/3 * pi * (3.5ft)^3 / 8 = 22.45 ft^3
Total volume = (Volume of cylinder) + (Volume of sphere) = (55.32 + 22.45) ft^3 = 77.77 ft^3
The tank holds 641 gallons since the volume of the tank is 85.66 cubic feet. The tank has a cylindrical part and two hemispheres.
What is the volume of the cylinder?The volume of the cylinder is V=Bh or V=2πrh.
Where B is the base area, h is the height of the cylinder and r is the radius.
What is the volume of the hemisphere?The formula for the volume of a hemisphere: V = (2/3)πr³
Where r is the radius of the hemisphere.
Calculating the Volume of the septic tank:The tank has a cylindrical part and two hemispheres.
So, the volume of the tank = (volume of the cylinder) +2 (volume of the hemisphere)
Finding the volume of the cylinder:
The height of the cylinder is h=5'9'' and the diameter is 3'6''.
(1 feet = 12 inches)
So, the diameter = 3 feet 6 inches = 3+(6/12) feet = 3.5 feet
Then, the radius r = 3.5/2 = 1.75 feet and
The height h=5 feet 9 inches = 5 + (9/12) feet = 5.75 feet
The volume of the cylinder = 2πrh
= 2π×1.75×5.75
= 63.22 cubic feet
Finding the volume of the hemisphere:
The diameter of the sphere is 3'6'' i.e., 3.5 feet
So, radius r = 1.75 feet
Then the volume of a hemisphere:
V = (2/3)πr³
= (2/3)π×(1.75)³
= 11.22 cubic feet
So,
The volume of the tank = (volume of the cylinder) +2 (volume of the hemisphere)
⇒ Volume of the tank = 63.22 + 2×11.22 =85.66 cubic feet.
Since it is given that for 1 cubic ft it holds 7.48 gallons then for 85.66 cubic ft it holds 85.66 × 7.48 = 640.73 gallons
Rounding to the nearest gallon. So, it holds 641 gallons.
