For (a): 52 + 35/10m, rationalizing the denominator gives the result (25√2 + 6√5)/10.
For (b): 33x + 3y/3xy, rationalizing the denominator gives the result √3(x+y)/xy.

To rationalize the denominator, we need to multiply both the numerator and denominator by the conjugate of the denominator. The conjugate of a binomial expression is the same expression with the sign between the terms changed. For example, the conjugate of (a+b) is (a-b) and the conjugate of (a-b) is (a+b). By multiplying by the conjugate, we eliminate any radicals in the denominator.

(a) 5/√2 + 3/√5

  = (5/√2)(√2/√2) + (3/√5)(√5/√5)

  = (5√2)/2 + (3√5)/5

  = (25√2 + 6√5)/10

(b) (3√3x + 3√y)/(3√xy)

  = (3√3x + 3√y)(3√xy)/(3√xy)(3√xy)

  = (9x√3xy + 9y√3xy)/(9xy)

  = (9√3xy(x+y))/(9xy)

The height of the helium tank is 49 inches.

Volume refers to the amount of space occupied by a three-dimensional object, measured in cubic units.

The volume V of a cylinder is given by the formula:

V = πr²h

where r is the radius of the base and h is the height of the cylinder.

Since the diameter of the helium tank is given as 14 inches, the radius r is half of the diameter, which is 7 inches.

We also know that the volume inside the tank is 2,401π cubic inches. Therefore, we can write:

2,401π = π(7)²h

Simplifying the right-hand side, we get:

2,401π = 49πh

Dividing both sides by 49π, we get:

h = 2,401π / 49π

Simplifying, we get:

h = 49

The length of MN, to the nearest tenth of a unit is equal to: C. 14.4 units.

In order to determine the missing side length of a geometric figure with the adjacent and hypotenuse side lengths given, you should apply the law of cosine:

C² = A² + B² - 2(A)(B)cosθ

Where:

A, B, and C is the length of side of a given triangle.

By substituting the given side lengths and angle into the law of cosine formula, we have the following;

MN² = LM² + LN² - 2(LM)(LN)cosθ

MN² = 12² + 10² - 2(12)(10)cos(52)

MN² = 144 + 100 - 147.76

There will be 22 blue signs at the end of the event.

The probability of an event can be determined by dividing the number of favorable outcomes by the total number of possible outcomes. For example, the probability of rolling a six on a standard six-sided die is 1/6, as there is only one favorable outcome (rolling a six) out of six possible outcomes (rolling a one, two, three, four, five, or six).

To solve this problem, we need to consider the factors that determine whether a house's sign will be flipped or not. A sign will only be flipped if the number of residents can divide the house number. For example, the sign on house number 12 will be flipped by the residents of that house because 12 is divisible by 2, 3, 4, and 6 (the factors of 12).

At the beginning, all signs are red, which means that none of the houses have had their sign flipped yet. Let's start with house number 1 and consider which houses will flip its sign.

For house number 1, its sign will not be flipped because 1 is only divisible by 1.

For house number 2, its sign will be flipped because 2 is divisible by 2.

For house number 3, its sign will not be flipped because 3 is only divisible by 1 and 3.

For house number 4, its sign will be flipped because 4 is divisible by 2 and 4.

For house number 5, its sign will not be flipped because 5 is only divisible by 1 and 5.

And so on, continuing this process for all 500 houses.

We can see that the signs on the houses with numbers that have an odd number of factors will end up blue, and the signs on the houses with numbers that have an even number of factors will end up red. This is because a factor always comes in pairs, except when the number is a perfect square, in which case the factor pair is identical (e.g. 4 has factors 1, 2, and 4, which is an odd number of factors).

So we need to count the number of integers from 1 to 500 that have an odd number of factors. These are the perfect squares, which are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400, 441, and 484.

All the real solutions of the equation are x=3, x=1, and x=-2. The rational root theorem states that any rational root of the equation x³-2x²-5x+6=0 can be written in the form p/q, where p is a factor of the constant term (6) and q is a factor of the leading coefficient (1). Therefore, the possible rational roots of the equation are: ±1, ±2, ±3, ±6

Answer:

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, and c are the side lengths of the triangle, and A, B, and C are the opposite angles, respectively.

We are given A, C, and c, so we can use the Law of Sines to find B, a, and b.

a/sin(A) = c/sin(C)

a/sin(22) = 2.69/sin(51.4)

a = sin(22) * (2.69/sin(51.4))

a = 1.00

b/sin(B) = c/sin(C)

b/sin(B) = 2.69/sin(51.4)

b = sin(B) * (2.69/sin(51.4))

We can use the fact that the sum of the angles in a triangle is 180 degrees to find B:

B = 180 - A - C

B = 180 - 22 - 51.4

B = 106.6

Now we can substitute the values we have found into the Law of Sines to find b:

a/sin(A) = b/sin(B)

1/sin(22) = b/sin(106.6)

b = sin(106.6) * (1/sin(22))

b = 2.69

Therefore, B is approximately 106.6 degrees, a is approximately 1.00, and b is approximately 2.69.

False, you need at least one angle and three sides to use the law of sines    or two angles  and two different sides.

sin A    sin B   sin C

------  = ------- = -------

 a           b           c

True, the law of sines can be used when you are given 3 sides of a triangle, and you are solving for an angle.

The law of sines states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all sides and angles in a given triangle. Therefore, if you know the lengths of all three sides of a triangle, you can use the law of sines to solve for one of the angles.

An angle is the measure that determines two straight lines, which when joined together create a point of origin, which is called the vertex of the angle.

Helping in Jesus' name.

Gail should pick a Beautiful bank if she plans to have her money in the account for 15 years.

To determine which bank would be better for Gail, we need to calculate the future value of her investment after 15 years for each bank and compare the results.

For Neighborhood Bank, we can use the formula:

FV = P(1 + r/n)^(n*t)

where FV is the future value,

P is the principal (the initial amount invested),

r is the annual interest rate (as a decimal),

n is the number of times the interest is compounded per year,

and t is the number of years.

Plugging in the values, we get:

FV = 5,500(1 + 0.012/1)^(1*15)

FV = 5,500(1.012)^15

FV = 7,130.34

For Beautiful Day Bank, we can use the formula:

FV = P(1 + r/n)^(n*t)

Plugging in the values, we get:

FV = 5,500(1 + 0.012/365)^(365*15)

FV = 5,500(1.000032876)^5475

FV = 7,145.25

-2A is defined, since we can multiply a matrix by a scalar. To find the result, we simply multiply each element of A by -2:

-2A = [-2(2) -2(0) -2(-1); -2(4) -2(-3) -2(2)] = [-4 0 2; -8 6 -4]

B - 2A is defined, since both matrices have the same dimensions. To find the result, we first compute -2A as shown above, then subtract each corresponding element of B and -2A:

B - 2A = [7 -5 1; 1 -4 -3] - [-4 0 2; -8 6 -4] = [7-(-4) -5-0 1-2; 1-(-8) -4-6 -3-(-4)] = [11 -5 -1; 9 -10 1]

AC is undefined, since the number of columns in A (3) does not match the number of rows in C (2).

CD is defined, since the number of columns in C (2) matches the number of rows in D (2). To find the result, we multiply each row of C by each column of D and sum the products:

The set of vectors {v1, v2, v3} is linearly dependent for all real number h ≠ 4 and all real number h ≠ -4.

The set of vectors {v1, v2, v3} is linearly dependent if there exists a set of real numbers a, b, and c such that a*v1 + b*v2 + c*v3 = 0 and at least one of a, b, or c is not equal to zero. In this case, we can write the equation as:

a*1 + b*2 + c*(-1) = 0

We can rearrange this equation to solve for h:

h = -a - 2*b + c

Now we can plug in the values for v1, v2, and v3:

h = -1 - 2*2 + (-1)*(-1)

h = -4

Therefore, the set of vectors {v1, v2, v3} is linearly dependent when h = -4.

Alternatively, we can also use the determinant of the matrix formed by the vectors to determine when the set is linearly dependent. The determinant of the matrix is given by:

| 1 2 -1 |
| -1 1 3 | = (1)(1)(h) + (2)(3)(-1) + (-1)(-1)(2) - (-1)(1)(-1) - (2)(-1)(1) - (1)(3)(2)
| 2 1 h |

Simplifying this equation gives:

h - 6 - 2 + 1 + 2 - 6 = 0

h - 11 = 0

h = 11

Therefore, the set of vectors {v1, v2, v3} is also linearly dependent when h = 11.

So the set of vectors {v1, v2, v3} is linearly dependent for all real number h ≠ 4 and all real number h ≠ -4.

The solutions to this problem are y = 5 and y = -1/3.

Sure! The quadratic formula is a useful tool for solving equations of the form ax^2 + bx + c = 0. In this problem, we need to rearrange the equation so that it fits this form before we can use the quadratic formula.

First, let's multiply both sides of the equation by y to get rid of the fraction:

y^2 + 1 = 13y/6

Next, let's rearrange the equation so that it equals zero:

y^2 - 13y/6 - 1 = 0

Now we can use the quadratic formula to solve for y. The quadratic formula is:

y = (-b ± √(b^2 - 4ac))/(2a)

In this problem, a = 1, b = -13/6, and c = -1. Plugging these values into the quadratic formula gives us:

y = (-(-13/6) ± √((-13/6)^2 - 4(1)(-1)))/(2(1))

Simplifying the equation gives us:

y = (13/6 ± √(169/36 + 4))/2

Finally, we can solve for y by simplifying the square root and dividing by 2:

y = (13/6 ± √(289/36))/2

y = (13/6 ± 17/6)/2

y = (30/6)/2 or y = (-4/6)/2

y = 5 or y = -1/3

So the solutions to this problem are y = 5 and y = -1/3. I hope this helps! Let me know if you have any further questions.

Lee's gross pay is $472.

First, we need to calculate the commission Lee earned. To do this, we take her total sales and multiply it by her commission rate.

Commission = Total Sales x Commission Rate

Commission = $4,000 x 0.04

Commission = $160

So, Lee earned $160 in commission.

Next, we need to calculate her base pay. To do this, we multiply her hourly rate by the number of hours she worked.

Base Pay = Hourly Rate x Hours Worked

Base Pay = $8.00 x 39

Base Pay = $312

Now that we have calculated her commission and base pay, we can add them together to find her gross pay.

Gross Pay = Base Pay + Commission

Gross Pay = $312 + $160

Gross Pay = $472

This means that before any deductions (such as taxes), Lee would earn $472 for working 39 hours and making $4,000 in sales.

The polynomial equation in the complete 30x^(4)+83x^(3)-52x^(2)+4x+1=0. The solutions are: x = -1 and x = -1/7, 1/7, -5/7, 5/7.

The question asks you to solve the polynomial equation: 30x4 + 83x3 - 52x2 + 4x + 1 = 0.

To solve this equation, you will need to factor it into the form (ax + b)(cx + d) = 0. The solutions of this equation will be when either ax + b or cx + d are equal to 0.

First, factor out the Greatest Common Factor (GCF) of the polynomial, which is 4x. This will leave us with:

4x(7x3 + 20x2 - 13x + 1) = 0.

Now, factor this expression into two binomials. One of the binomials is already in the form ax + b, and the other will need to be factored further.

4x(7x2 + 5x - 1)(x + 1) = 0.

Therefore, the solutions of this equation are when

If A varies directly as B and inversely as C then The value of A when B is 12 and C is 3 is 16.

To find the value of A, we can use the formula for direct and inverse variation of the given :
A = k*B/C

We are given that A is 12 when B is 6 and C is 2. We can plug these values into the formula to find the value of k:
12 = k*6/2
12 = 3k
k = 4

Now that we know the value of k, we can plug in the new values for B and C to find the value of A:
A = 4*12/3
A = 48/3
A = 16

Therefore, the value of A when B is 12 and C is 3 is 16. The correct answer is O 16.
