The value of n when b = 1,024, a = 16, and r = 2 is 7.

The student is asking to solve for n in the formula of the nth term of a geometric series given the formula b = ar^(n-1) and the values of b, a, and r. To find the value of n, we can substitute the known values into the formula and solve for n.

b = 1,024

a = 16

r = 2

Using these values:

Substitute the known values into the formula: 1,024 = 16 imes 2^(n-1)

Divide both sides by 16: 64 = 2^(n-1)

Recognize that 64 is 2 to the power of 6: 2^6 = 2^(n-1)

Therefore, n - 1 = 6

Add 1 to both sides to find n: n = 7

The value of n when b = 1,024, a = 16, and r = 2 is 7.

Onto the desserts, there are 5 desserts and 2 out of the 5 you put it together with the lunches that have a main course and appetizers. Next, there are 3 drinks and 2 of those 3 you would put it with the 2 meals that has an appetizer,main course,dessert, and now a drink. In the end, Its only possible that there are 2 lunch special being able to be made. With all the food

Answer: 150

Step-by-step explanation:

We know that a complete lunch meal consist of an appetizer , a main course , a dessert and a drink.

Given: The number of appetizers=2

The number of main courses=5

The number of desserts=5

The number of drinks=3

Therefore, the number of possible lunch meals will be :

Answer:

Step-by-step explanation:

The domain of that function is all real numbers.  The x values will drop into negative infinity and will grow to positive infinity.

The range is found from the vertex form of a parabola, which is

[tex]y=(x-h)^2+k[/tex]

where h indicates side to side movement of the vertex and k indicates up or down.  Our function has a +3 at the end of it and is positive (so it opens upwards), so the range is y ≥ 3.

To find the inverse of that function, switch the x and y coordinates and solve for the new y.  Let f(x) be y, then switch the x and y:

[tex]x=y^2+3[/tex]

Now solve for the new y:

y = ±[tex]\sqrt{x-3}[/tex]

To find the domain of a radical, set the radicand greater than or equal to 0 and solve for x (this is because the radicand cannot be a negative number or we are dealing with imaginary numbers and that's not what you want.  BTW, a radicand is the term under the radical sign).  

x - 3 ≥ 0  so   x ≥ 3.  The domain of the inverse is all real numbers greater than or equal to 3.

This is a sideways parabola (the inverse is), and it opens to the right starting at the x value of 3.  It will grow into positive values of y to infinity and will drop into negative values of y into negative infinity.

Just a little trick here to remember, and it ALWAYS holds true:  the domain of a function is the range of its inverse, and the range of a function is the domain of its inverse.  Look to our solution for your problem here and you'll see that it is true.

Answer:

t = 6: It takes 6 seconds for the object to hit the ground

Step-by-step explanation:

So, we need to find t when the height is 0. Since -5t² + 20t + 60 represents the height, that needs to equal 0.

Equation: -5t² + 20t + 60 = 0

Divide by -5: t² - 4t - 12 = 0

Find two numbers that add up to -4t and multiply to -12t²: -6t, 2t

Substitute: t² - 6t + 2t - 12 = 0

Factor: (t - 6)(t + 2) = 0

Answers: t = 6, t = -2

Since time can't be negative, t = 6.

To determine the time it takes for the object to hit the ground, the quadratic equation -5t^2 + 20t + 60 = 0 is solved, leading to the conclusion that it takes 6 seconds for the object to reach the ground.

The question asks, "How many seconds does it take for the object to hit the ground?" given the function f(t) = -5t2 + 20t + 60. To find when the object hits the ground, we need to determine when the height f(t) is equal to 0. This involves solving a quadratic equation.

Steps to Solve:

Set the equation equal to zero: -5t2 + 20t + 60 = 0.

Divide the entire equation by -5 to simplify: t2 - 4t - 12 = 0.

Use the quadratic formula: t = (-B ± √(B2 - 4AC)) / 2A, where A = 1, B = -4, and C = -12.

Calculate the discriminant: √((-4)2 - 4(1)(-12)) = √(16 + 48) = √64 = 8.

Substitute values into the formula: t = (4 ± 8) / 2, yielding t = 6 seconds or t = -2 seconds.

Dismiss the negative value, as time cannot be negative, leaving t = 6 seconds as the solution.

Therefore, it takes the object 6 seconds to hit the ground after it is launched.

The product of prime polynomials is equivalent to Option (A)  [tex]3x(3x - 2)(4x + 1)[/tex].

In mathematics, an irreducible polynomial (or prime polynomial) is approximately a non-constant polynomial that cannot be factored into the product of two non-constant polynomials. The expression can be expressed in product of prime polynomial by converting it into the factored form.

Given polynomial expression = [tex]36x^{3} - 15x^{2} - 6x[/tex]

Solving the polynomial expression in factored form -

⇒ [tex]3x(12x^{2} - 5x - 2)[/tex]

⇒ [tex]3x(12x^{2} - 8x + 3x - 2)[/tex]

⇒ [tex]3x[4x(3x - 2) + 1(3x - 2)][/tex]

⇒ [tex]3x(3x - 2)(4x + 1)[/tex]

70 shirts per day

We simply need to find how many shirts would have been produced on the 8th day. This can be done by multiplying the number of extra shirts produced per day by the number of days extra shirts were produced. Since one day was skipped due to finishing early, there were 7 days of producing extra shirts.

7 times 10 equals 70. This means that 70 shirts would have been produced on the 8th day, which means the factory was planning on producing 70 shirts for every other day as well.

Answer:

x = 5/(10 - a - b)

Step-by-step explanation:

Solve for x:

4 + 3 x - a x = 9 - 7 x + b x

Collect in terms of x:

x (3 - a) + 4 = 9 - 7 x + b x

Collect in terms of x:

x (3 - a) + 4 = x (b - 7) + 9

Subtract (b - 7) x + 4 from both sides:

x (10 - a - b) = 5

Divide both sides by 10 - a - b:

Final answer:

The approximate area of a 212-degree sector with a 45m radius is 3371.26 m², and the approximate area of a 92-degree sector with a 9m diameter (4.5m radius) is 16.2 m².

Explanation:

To find the approximate area of a sector of a circle, we use the formula for the area of a circle, A = πr², and then adjust it for the sector by multiplying by the ratio of the central angle to 360 degrees. For Question 1, the central angle θ is approximately 212 degrees and the radius is 45 m. The formula for the sector area becomes A = (π × (45 m)² × (212/360)). A quick calculation gives us the following area:

For the first sector with a 212-degree angle and a radius of 45m:

A = 3.1415927 × (45 m)² × (212/360) = 3.1415927 × 2025 m² × 0.5889 ≈ 3371.26 m²

For Question 2, the central angle θ is approximately 92 degrees and the diameter is 9m, which makes the radius 4.5m. The formula for the sector area then becomes A = (π × (4.5 m)² × (92/360)). The calculation yields the following area:

A = 3.1415927 × (4.5 m)² × (92/360) = 3.1415927 × 20.25 m² × 0.2556 ≈ 16.2 m²

10y + 7 + 3(3y + 7) = 180

10y + 7 + 9y + 21 = 180

19y + 28 = 180

19y = 180 - 28

19y = 152

y = 152/19

y = 8

Plug back into Q and S.

Q = 10y + 7

Q = 10(8) + 7

Q = 80 + 7

Q = 87

S = 3(3y + 7)

S = 9y + 21

S = 9(8) + 21

S = 72 + 21

S = 93

Without solving for x to find the other angles, we can easily see that the answer is choice C.

Answer:

P = 61°

Q = 87°

R = 119°

S = 93°

Chris will earn $75 in interest in the first year by depositing $1,500 into a savings account with an annual interest rate of 5%, calculated using the simple interest formula.

To calculate the amount of interest Chris will earn in the first year the money is in the savings account, we will use the formula for simple interest, which is Interest = Principal × Rate × Time. In this case, the principal amount is $1,500, the annual interest rate is 5% or 0.05 when expressed as a decimal, and the time is 1 year since we are looking for the interest for the first year only.

Therefore, the interest Chris will earn after one year is calculated as follows:

Interest = $1,500 × 0.05 × 1

Interest = $75

Thus, at the end of the first year, Chris will have earned $75 in interest.
