Answer: The correct answer is (5, 11π/6). or C
Step-by-step explanation:
The polar coordinates of the point (x, y) = (5√3/2, -5/2) are (r, θ) = (5, 11π/6).
Explanation:
Using the formulas for converting Cartesian coordinates to polar coordinates:
r = √(x^2 + y^2)
θ = atan2(y, x)
Plugging in the given values:
r = √((5√3/2)^2 + (-5/2)^2)
= √(75/4 + 25/4)
= √(100/4)
= 5
θ = atan2(-5/2, 5√3/2)
≈ 11π/6 radians
So, the correct polar coordinates of the point (5√3/2, -5/2) are (r, θ) = (5, 11π/6).

what is 9 1/8 - 2 1/4 simplified?
Answer:
To simplify 9 1/8 - 2 1/4, we need to first convert the mixed numbers to improper fractions.
9 1/8 = (8 x 9 + 1)/8 = 73/8
2 1/4 = (4 x 2 + 1)/4 = 9/4
Now we can subtract the two fractions:
73/8 - 9/4
Since the two fractions have different denominators, we need to find a common denominator. The least common multiple of 8 and 4 is 8, so we can convert the second fraction to have a denominator of 8:
73/8 - (9/4)x(2/2) = 73/8 - 18/8 = 55/8
Therefore, 9 1/8 - 2 1/4 = 55/8, which is an improper fraction. If we want to convert it back to a mixed number, we can divide the numerator by the denominator:
55/8 = 6 7/8
So the simplified answer is 6 7/8. Answer: 6 7/8.

Find the polar coordinates of a point with Cartesian coordinates (x,y)=(√3,1).
(1,π/6)
(1,2π/3)
(2,7π/6)
(2,2π/3)
(2,π/6)
(1,7π/6)
Answer: The Correct answer is E (2,pie/6)
Step-by-step explanation:
To find the polar coordinates of a point given its Cartesian coordinates (x, y), we can use the following formulas:
r = √(x^2 + y^2)
θ = atan2(y, x)
where r is the radial distance from the origin to the point, and θ is the angle measured counterclockwise from the positive x-axis to the line connecting the origin and the point.
Given the Cartesian coordinates (x, y) = (√3, 1), we can plug these values into the formulas to find the polar coordinates:
r = √(√3^2 + 1^2) = √(3 + 1) = 2
θ = atan2(1, √3)
Using a calculator, we can find that θ is approximately 0.5236 radians.
So, the polar coordinates of the point (√3, 1) are (r, θ) = (2, 0.5236 radians).

d(x) = 600 − 0.8x, s(x) = 0.4x
(a) Find the market demand (the positive value of x at which the demand function intersects the supply function).
x =
Answer: The market demand is x = 750.
Step-by-step explanation:
Answer: The market demand is x = 750.
Explanation:
To find the market demand, we need to set the demand function equal to the supply function and solve for x:
d(x) = s(x)
600 − 0.8x = 0.4x
Combining like terms, we get:
600 = 1.2x
Dividing both sides by 1.2, we get:
x = 500
However, we need to find the positive value of x. Since x represents the quantity demanded, it cannot be negative.
Substituting x = 500 into both the demand and supply functions, we find that:
d(500) = 600 - 0.8(500) = 200
s(500) = 0.4(500) = 200
Since d(500) = s(500), x = 500 is not the market demand.
Substituting x = 750 into both the demand and supply functions, we find that:
d(750) = 600 - 0.8(750) = 0
s(750) = 0.4(750) = 300
Since d(750) = s(750), x = 750 is the market demand.
Therefore, the market demand is x = 750.

of the tangent line to the curve at the point (1, 1).
The equation of the tangent line at (1,1) is given as follows:
y - 1 = -0.25(x - 1).
How to obtain the equation of the tangent line?The curve for this problem is given as follows:
x² - y² = 2x + y + xy - 4.
Applying implicit differentiation, we obtain the slope of the tangent line, as follows:

Tom made some beads and packed all the bead in 14 small boxes and 3 large boxes. She filled each small box with the same number of beads and each large box with the same number of beads. There were 4 more beads in each large box than in each small box. 7/9 of the beads made were packed in the small boxes. How many beads were there in each small box?
Answer:
Each small box has 24/17 beads.
Step-by-step explanation:
Let's call the number of beads in each small box "s" and the number of beads in each large box "l".
We know that there are 14 small boxes, so the total number of beads in the small boxes is 14s. We also know that there are 3 large boxes, so the total number of beads in the large boxes is 3l.
From the problem, we know that there are 4 more beads in each large box than in each small box, so we can write:
l = s + 4
We also know that 7/9 of the total number of beads were packed in the small boxes, so we can write:
14s + 3l = 7/9(total number of beads)
We can simplify this expression by substituting l = s + 4:
14s + 3(s + 4) = 7/9(total number of beads)
Expanding and simplifying:
17s + 12 = 7/9(total number of beads)
Now, we need one more equation to solve for s. We know that the total number of beads is equal to the sum of the beads in the small and large boxes:
total number of beads = 14s + 3(s + 4)
Simplifying:
total number of beads = 17s + 12
Now we have two equations that we can use to solve for s:
17s + 12 = 7/9(total number of beads)
total number of beads = 17s + 12
We don't know the total number of beads, but we do know that it is a multiple of both 14 and 3 (since there are 14 small boxes and 3 large boxes). The smallest multiple of both 14 and 3 is 42, so let's assume that the total number of beads is 42x, where x is some number.
Substituting 42x for "total number of beads" in the two equations:
17s + 12 = 7/9(42x)
42x = 17s + 12
Simplifying:
153s + 108 = 98x
42x = 17s + 12
Now we have two equations and two unknowns (s and x). We can solve for s in terms of x by isolating s in the second equation:
17s = 42x - 12
s = (42x - 12)/17
We can substitute this expression for s into the first equation:
17((42x - 12)/17) + 12 = 7/9(42x)
Simplifying:
42x - 12 + 12 = 14x
28x = 24
x = 24/28 = 0.857
Now we know that the total number of beads is:
42x = 42(0.857) = 36
And we know that each small box has:
s = (42x - 12)/17 = (36 - 12)/17 = 24/17
So each small box has 24/17 beads.

An employee is considering two job offers.
First offer: $57,000 yearly salary with an 8% matching 401k
Second offer: $63,000 yearly salary with a 4% matching 401k
Let's calculate the total value of the second offer after 4 years:
Yearly salary is : $63,000
Total gross income after 4 years: $63,000 x 4 = $252,000
The company matches 5% of the employee's salary.
So, the employee contributes 5% of $63,000 = $3,150 per year
After 4 years,
Company matches: $3,150 x 4 = $12,600
Employee contributions: $3,150 x 4 = $12,600
Total 401k contributions: $12,600 + $12,600 = $25,200
The total value of the second offer after 4 years is:
Total value: $252,000 + $25,200 = $277,200
Now, let's compare this to the total value of the first offer, which is : $255,360.
Therefore, the second job offer is better by:
$277,200 - $255,360 = $21,840

Suppose you deposit $1000 in a savings account that pays interest at an annual rate of 6%. If no money is added or withdrawn from the account, answer the following questions.
a. How much will be in the account after 4 years?
b. How much will be in the account after 16 years?
c. How many years will it take for the account to contain $1,500?
d. How many years will it take for the account to contain $2,00?
Answer:
a. $1,240
b. $1,960
c. 9 years
d. 17 years
Step-by-step explanation:
For interest you multiply the percent with 1,000 and add the number you get for your answer. So 1,000 times 6% is 60. Each year the account earns $60 worth of interest. You multiply 60 by 4 and your result is 240. You add 240 to 1,000 and get your answer for a $1,240.
You repeat the same process for b. 16 times 60 is 960. You add 960 and 1,000 and your answer is $1,960.
So we know the account already has $1,000 so all that has to be done is to divide 500 by 60 and your result is 8.3. However you it is anual interest so you cannot but in a decimal so you round up to 9. Making it 9 years
Same process dividing 1,000 by 60 which gives you 16.6 rounding up to 17. Making it 17 years.

The sides of a triangle are 30, 64, and 90. Use the Pythagorean Theorem to determine if the triangle is right, acute, or obtuse.
Answer:
The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Let's check if the triangle with sides of 30, 64, and 90 is a right triangle:
30^2 + 64^2 = 900 + 4096 = 4996
90^2 = 8100
Since 4996 is less than 8100, the triangle is not a right triangle.
In an acute triangle, all angles are less than 90 degrees. In an obtuse triangle, one angle is greater than 90 degrees.
To determine if the triangle is acute or obtuse, we need to find the largest side. The largest side is 90. Let's find the sum of the squares of the other two sides:
30^2 + 64^2 = 900 + 4096 = 4996
Since 4996 is less than 90^2, the triangle is acute.
Therefore, the triangle with sides of 30, 64, and 90 is an acute triangle.
the triangle is obtuse
Step-by-step explanation:
[tex] {90}^{2} = 8100[/tex]

{0, −1, −3, −6, −10, ...}; S14
S14=
Answer:
-91
Step-by-step explanation:
To find the partial sum for the sequence
[tex]\large \boxed{\mathrm{ \ 0, \ -1, \ -3, \ -6, \ -10,}}[/tex]
We first notice that the first term is
[tex]\large \boxed{\mathrm{0}}[/tex],
And each subsequent term is the sum of the previous term and the next integer in the sequence starting with [tex]-1.[/tex] Therefore, we can use the formula for the sum of an arithmetic series to find the partial sum S14:
S14 = 14/2 * (2(0) + (14-1)(-1+0)/2) = 14/2 * (13/2 * -1) = -91
Therefore, the partial sum for the sequence up to the [tex]14th[/tex] term is [tex]-91.[/tex]
Answer:
[tex]91[/tex]
Step-by-step explanation:
The partial sum of a sequence is the sum of a certain number of terms in the sequence. For the given sequence
{0, −1, −3, −6, −10, ...},
The nth term can be represented as Tn = n(n-1)/2. This means that the partial sum of the first 14 terms of the sequence, denoted by S14, can be calculated by adding up the first 14 terms using the formula: S14 = 0 + (-1) + (-3) + (-6) + (-10) + ... + T14.
Simplifying this expression using the formula for Tn, We get S14 = 91. Therefore, the partial sum for the given sequence up to the 14th term is equal to 91.
