Answer: 75.6, 14.4

Step-by-step explanation:

Note 2 angles are complementary if they adds up to 90 degrees. Lets set x to be the first angle.

x - (x - 61.2) = 90

Then we can know:

2x = 90 + 61.2;

2x = 151.2;

x = 75.6

Now we know the first angle is 75.6, we know the second angle is 75.6 - 61.2 = 14.4. Hope you find this helpful!

Answer & Explanation:

sin Θ = opp/hyp

cos Θ = adj/hyp

tan Θ = opp/adj

csc Θ = hyp/opp

sec Θ = hyp/adj

cot Θ = adj/opp

1.

sin Θ = opp/hyp = (8√2)/18 = (4√2)/9

cos Θ = adj/hyp = 14/18 = 7/9

tan Θ = opp/adj = (8√2)/14 =  (4√2)/7

csc Θ = hyp/opp = 18/(8√2) = (9√2)/(4√2√2) = (9√2)/8

sec Θ = hyp/adj = 18/14 = 9/7

cot Θ = adj/opp = 14/(8√2) = (7√2)/(4√2√2) = (7√2)/8

Answer:

Step-by-step explanation:

The factored form of a polynomial function with roots r1 and r2 can be found by multiplying two linear factors (x - r1) and (x - r2).

Here are the steps to find the factored form of the polynomial function with roots 3i and 2:

Write the first linear factor: (x - 3i)

Write the second linear factor: (x - 2)

Multiply the two linear factors: (x - 3i)(x - 2)

Expand the product to find the polynomial function:

x^2 - (3i + 2)x + (3i * 2) = x^2 - 2x - 6i

And there you have it, the factored form of the polynomial function with roots 3i and 2 is x^2 - 2x - 6i.

Answer: 200 dollars more

Step-by-step explanation: I did 30% of 500 which is 150 that Noel has.

70% of 500 which is 350. 350-150 is 200

Frank has saved 200$ more than Noel

Answer: 200 dollars

The first step that we should do is divide 500 into 10 separate parts. Each part is 10 percent of the price. 500 divided by 10 is 50.

This means that Frank saved 50 x 7 and Noel saved 50 x 3.

50 x 7 is 350 and 50 x 3 is 150.

Frank saved 350 , while Noel saved 150.To check if we are correct we can add 350 and 150, which is 500 that brings us back to our original answer. Next we must subtract Franks total from Noel to figure out the difference.

350-150 is 200.

This means that Frank saved 200 more dollars than Noel.

The probability of spinning a number greater than 4 on a spinner with 6 equal sections is 1 over 3. (option d)

A spinner with 6 equal sections has an equal probability of landing on any of the 6 sections. To find the probability of spinning a number greater than 4, we need to find the fraction of sections that meet this criterion. In this case, there are 2 sections that satisfy this condition (5 and 6).

Therefore, the probability of spinning a number greater than 4 is 2/6, or 1/3.

It's important to remember that when working with probability, the values can only be between 0 and 1, with 0 indicating an impossible event and 1 indicating a certain event. The probability of any event must be a number between 0 and 1, inclusive.

The sample should be milled to a radius that is approximately 7.19 times its original radius in order to increase its work function by 2%.

The work function of a material is related to its surface area, and milling a sample into smaller nano-spheres increases its surface area. The increase in work function can be approximated by the following equation:

ΔW = kTln(A/A₀)

where ΔW is the change in work function, k is Boltzmann's constant, T is the temperature in Kelvin, A is the new surface area of the milled sample, and A₀ is the original surface area of the sample.

To find the size to which the sample should be milled to increase its work function by 2%, we need to rearrange the equation to isolate the new surface area:

A/A₀ = e^(ΔW/kT)

Plugging in the known values, we get:

A/A₀ = e^(0.02 * 5.1 eV / (8.62 * 10⁻⁵ eV/K * 300 K))

= 51.64

The new surface area is 5064% larger than the original surface area.

Since the sample is being milled into nano-spheres, the new surface area is proportional to the square of the radius. Let's call the original radius of the sample "r₀". Then the new radius is:

r = √(A/A₀) * r₀ = √(51.64) * r₀ = 7.19 * r₀

The correct answer is option d. The length of the given hypotenuse  of a right triangle is 7 cm.

A right triangle has side lengths of 4 centimeters and 5 centimeters, so we can use the Pythagorean Theorem to find the length of the hypotenuse. The theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. In this case, the hypotenuse c is given by

Then, use the given information to calculate the granddaughter's age in 8 years: 8 + 8 = 16.

Finally, use the given information to calculate the grandfather's age now: 5 x 16 = 80, so 80/5 = 16, and 16 x 9 = 72.

Answer: (-4, 1)

Step-by-step explanation:

To solve graphically, change each equation into slope-intercept form

(y = mx + b)

3x + 4y = -8

+8 +8

3x + 4y + 8 = 0

-4y -4y

3x + 8 = -4y

Divide both sides by -4 to get y by itself

-3/4x - 2 = y or y = -3/4x - 2

Do the same for the other equation.

-x + y = 5

y = 5 + x or y = x + 5

Answer:

If csc = 29/21, then the reciprocal of this is equal to the sine of the angle. So,

sin = 21/29.

Since cosine is less than 0, then the angle must be in the second or third quadrant, which means that the sine of the angle must be positive. So,

sin = 21/29, and cos = -√(1 - sin^2) = -√(1 - (21/29)^2)

Next, we can find the tangent by taking the ratio of sine to cosine:

tan = sin / cos = 21/29 / -√(1 - (21/29)^2) = -21/√(841 - 441)

Finally, we can find the cotangent by taking the reciprocal of the tangent:

cot = 1 / tan = -√(841 - 441) / 21

So, the remaining trigonometric functions are:

sin = 21/29

cos = -√(1 - (21/29)^2)

tan = -21/√(841 - 441)

cot = -√(841 - 441) / 21

The monthly payment on a loan and the total interest that will be paid during the term of the loan can be found using an amortization formula.

Here are the steps to find the monthly payment and total interest for the given loan conditions:

Convert the interest rate to a decimal: 7.5% = 0.075

Divide the interest rate by the number of periods (months) per year: 0.075 / 12 = 0.00625

Find the number of payment periods: 8 years * 12 months/year = 96

Calculate the monthly payment using the amortization formula:

Payment = Loan Amount * (Interest Rate / (1 - (1 + Interest Rate)^(-Number of Payments)))

Payment = $6,200 * (0.00625 / (1 - (1 + 0.00625)^(-96)))

Payment = $79.88

So, the monthly payment on the loan is $79.88.

Calculate the total interest paid over the term of the loan:

Total Interest = (Monthly Payment * Number of Payments) - Loan Amount

Total Interest = ($79.88 * 96) - $6,200

Total Interest = $7,538.88

So, the total interest that will be paid during the term of the loan is $7,538.88.

It is possible to choose a and b such that the value of function(x) at any given point is equal to the limit of f(x) as x approaches any value. This guarantees that f is continuous throughout.

A function's limit as x approaches any value must match the value of f(x) at that moment in order for the function to be continuous everywhere. In order to ensure that this need is satisfied, the values of a and b that make up f(x), whether it be a linear equation, polynomial, or another sort of equation, must be chosen. Since the behaviour of the function varies smoothly as x approaches any value, this ensures that the function is continuous throughout. In other words, a and b values must be selected in a way that the function is continuous, i.e., defined and devoid of breaks or discontinuities.

Speed against the wind = x - y

Speed with the wind = x + y

Total distance covered by plane = 360 miles

Time taken against the wind = 2 hours 15 minutes

                                               = 2 ( 1/4 ) hours

                                               = 9 / 4 hours

Time taken with the wind = 1 hour 30 minutes

                                          = 1 ( 1/2 ) hours

                                          = 3 /2 hours

Speed = distance / time

Against the wind :

So that,

The ratio of ages in the current year:

Mr Lim's age to his son's age = 5x : 2x

a : b = 5x : 2x

Mr Lim's age be in 6 years time = 40 + 6
