The distance from the base's center at that time is 18 feet.

What is function?

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input.

A function is typically represented as y = f. (x).

h(x) = 16 ft x is the distance from the base when

h(x) = 16 h(x) = -IxI + 34

when a raindrop falls from the end of the roof.

16 = -IxI + 34

IxI = 34 – 16 = 18

It might land on the roof's opposite end.

Answer:

2) 1885 km

3) 795 h 46 m 29 s

Step-by-step explanation:

2)

C = 2πr

C = 2 × 3.14159 × 300 km

C = 1885 km

3)

(1000000 km)/ (1885 km/tour) = 530.16477 tours

1 tour = 1 h 30 m = 1.5 h

530.16477 tours = 530.16477 × 1.5 h = 795.7747155 h = 795 h 46 m 29 s

For Deepa to find his yearly balance in a single step, he must multiply his money by 1.01

Simple interest is often a predetermined percentage of the principle amount borrowed or lent paid or received over a specific time period. Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.

The following calculation must be done in order to determine what Deepa should multiply his current balance by in order to find his total balance in a year in one step if no money will be added to or removed from the investment. Deepa invests money in an account that pays a simple interest rate of 1% per year.

Current balance = X

Interest = 1% = 1/100 = 0.01

Interest + principal = 1.01

1.01X = Total balance in a year

Deepa must therefore multiply her money by 1.01 in order to determine it in a single step.

The largest value of x that satisfies the inequality is approximately -1.8639.

To find the largest possible value of x that satisfies the inequality 1/(x + 2)⁶ > 1,000,000, we can start by rearranging the inequality:

1/(x + 2)⁶ > 1,000,000

Taking the reciprocal of both sides:

(x + 2)⁶ < 1/1,000,000

Now, let's take the sixth root of both sides:

x + 2 < (1/1,000,000)[tex]}^{1/6[/tex]

Calculating the right side:

x + 2 < 0.1361

Subtracting 2 from both sides:

x < 0.1361 - 2

x < -1.8639

Therefore, the largest value of x that satisfies the inequality is approximately -1.8639.

The range of the function is {0, 4, 10}. Option A. {0, 4, 10}

The concept used in finding the range of a function is called functional mapping, which maps the elements in the domain of the function to the corresponding elements in the range.

In this problem, we took a set of values in the domain of the function (which was {-2, 0, 3}) and evaluated the function for each of those values to find the corresponding outputs in the range of the function, which was {0, 4, 10}.

To find the range of the function f(x) = 2x + 4 for the domain {-2, 0, 3}, we need to calculate the output of the function for each of the values in the domain:

For x = -2: f(-2) = 2 * -2 + 4 = -4 + 4 = 0

For x = 0: f(0) = 2 * 0 + 4 = 4

For x = 3: f(3) = 2 * 3 + 4 = 10

Therefore, the range of the function is {0, 4, 10}. Option A. {0, 4, 10}

The range of the function f(x) = 2x+4 when the domain is {-2,0,3} is {0,4,10} .

The range for this function would be {0,4,10}.

Given, Function f(x) = 2x+4

Domain = {-2,0,3}

After putting the value of x= -2 in the function f(x) =2x+4 ,

f(-2) = 2×-2+4 = -4+4= 0

After putting the value of x= 0 in the function f(x) = 2x+4

f(0)= 2×0+4 =0+4=4

After putting the value of x= 3 in the function f(x) = 2x+4

f(3) =2×3+4= 6+4= 10

The area of the small indoor greenhouse (herbarium) is equal to 4,250 cm².

The length of tape needed for all the 12 edges is equal to 320 cm.

Mathematically, the total surface area (TSA) of this glass panes (including base) can be calculated by using this mathematical expression:

Total surface area (TSA) = 2[lb + lh + bh]

Where:

Total surface area (TSA) = 2[(30 × 25) + (30 × 25) + (25 × 25)]

Total surface area (TSA) = 2[750 + 750 + 625]

Total surface area (TSA) = 2[2,125]

Total surface area (TSA) = 4,250 cm².

Next, we would determine the length of tape needed for all the 12 edges by using this mathematical expression:

Total length = 4(l + b + h)

Total length = 4(30 + 25 + 25)

Total length = 4(80)

Total length = 320 cm.

The local maximum is x = 13.5 with a value of g(13.5) = (13.5)^2 - 27 * 13.5 = g(13.5) = 125.375.

(a) To determine whether a function is even, odd, or neither, we need to check if g(x) = g(-x) for all x (even), g(x) = -g(-x) for all x (odd), or neither.

g(x) = x^2 - 27x is neither even nor odd because it does not satisfy either of the two conditions for even or odd functions.

(b) To determine the local maximum, we need to find the critical points (points where the derivative is equal to zero or undefined) and then determine if they are local maxima, local minima, or neither.

g'(x) = 2x - 27, which has critical points at x = 13.5 and x = 0. Since g'(x) > 0 for x < 0 and g'(x) < 0 for x > 0, x = 0 is a local minimum. Since g'(x) < 0 for x < 13.5 and g'(x) > 0 for x > 13.5, x = 13.5 is a local maximum.

Therefore, the local maximum is x = 13.5 with a value of g(13.5) = (13.5)^2 - 27 * 13.5 = g(13.5) = 125.375.

Answer:

the Distance Between the two points a and b

Step-by-step explanation:

Distance between two points is the length of the line segment that connects the two points in a plane. The formula to find the distance between the two points is usually given by d=√((x2 – x1)² + (y2 – y1)²). This formula is used to find the distance between any two points on a coordinate plane or x-y plane.

The boat is approximately 515 feet away from the lighthouse.

To find the distance from the boat to the lighthouse, we can use trigonometry. The angle of depression from the person to the boat is 28°, and the height of the lighthouse is 200 feet. Let's call the distance from the boat to the lighthouse x. Using the tangent function, we have

Solving for x, we have x = 200 / tan 28°. Approximating this value using a calculator, we have x ≈ 514.7 feet. Rounding to the nearest foot, the boat is approximately 515 feet away from the lighthouse.
