Answer:

62.2 m

Step-by-step explanation:

From 148m away at ground level, the angel of elevation to the tower base is 18 degrees. Imagining this as a right angled triangle, if considering the angle of 18 degrees, 148m is the adjacent and the opposite is the height of the hill:

tanA=opposite/adjacent

tan18=opposite/148

opposite = 57.8357059295m

From 148m away at ground level, the angel of elevation to the tower top is 34 degrees. Imagining this as a right angled triangle, if considering the angle of 34 degrees, 148m is the adjacent and the opposite is the height of the hill+the tower:

tanA=opposite/adjacent

tan34=opposite/148

opposite = 120.062515998m

Knowing the height of the hill and tower is 120.062515998m and the height of the hill is 57.8357059295m, we can say the height of the tower is the difference:

120.062515998 - 57.8357059295 = 62.2268100685 m

A ratio has two or more numbers that symbolize relation to each other. Ratios are used to compare the numbers, and you can compare them using division.

To find out what the simplest form is of the ratio 5: 2[tex]\frac{1}{2}[/tex], we can divide both sides by 2[tex]\frac{1}{2}[/tex].

The ratio simplified is 2: 1.

To determine the simplest form of the ration 5 : [tex]2\frac{1}{2}[/tex] , we can first simplify the mixed fraction [tex]2\frac{1}{2\\}[/tex]

So, [tex]2\frac{1}{2\\}[/tex] = [tex]\frac{5}{2}[/tex]

∴ 5 : [tex]2\frac{1}{2\\}[/tex] = 5 : [tex]\frac{5}{2}[/tex]

            = ( 5 x 2 ) : ( [tex]\frac{5}{2\\}[/tex] x 2 )

            =  10 : 5

            =  [tex]\frac{10}{5}[/tex] x [tex]\frac{5}{5}[/tex]

            =  2 : 1

Hence, the simplest form of the ratio given is 2 : 1

The area between the graph of f and the x-axis on the interval [-8, 0] is 4608 square units.

The two-dimensional region enclosed by the function's graph and the x-axis is referred to as the region between the graph and the x-axis. Calculating the definite integral of the function over the specified interval and deducting the area below the x-axis, if any, will yield the area of this region.

There are two sections to the graph of f(x) = |x3 - 64|: a parabolic section and a linear section. The area between the graph of f and the x-axis is just the absolute value of the definite integral of f(x) over [-8, 0] because the graph of f(x) on the interval [-8, 0] is below the x-axis and contains negative values.

We must first get the antiderivative of f(x) before we can determine the definite integral, which may be accomplished by utilising partial fraction decomposition.

The antiderivative of f(x) = x⁴ - 64 is:

F(x) = (x⁴)/4 + 64x

The definite integral of f(x) over [-8, 0] is:

Area = F(0) - F(-8) = (0⁴)/4 + 64(0) - ((-8)⁴)/4 - 64(-8) = (8⁴)/4 + 64(8) = 4096 + 512 = 4608

Charlotte makes 500 pounds per week

30 % of 500 she has to pay to the commission per week

if she made 1575 one week how much would she get?

1575 divided by 30%=472.5

472.5 rounded = 473

x=473 or 472.5

Charlotte would make $972.50 in a week in which she made $1575 in sales and  if Charlotte made x dollars in sales, she would make $500 + 0.3x in total earnings for the week.

percentage, a relative value indicating hundredth parts of any quantity.

To calculate how much Charlotte would make in a week in which she made $1575 in sales

we first need to calculate her commission:

Commission = 30% × $1575

= $472.50

Total earnings = Guaranteed salary + Commission

= $500 + $472.50

= $972.50

Therefore, Charlotte would make $972.50 in a week in which she made $1575 in sales.

To calculate how much Charlotte would make in a week if she made x dollars in sales, we can use the same method.

Her commission would be:

Commission = 30% ×x

And her total earnings would be:

Total earnings = Guaranteed salary + Commission

= $500 + 0.3x

So, if Charlotte made x dollars in sales, she would make $500 + 0.3x in total earnings for the week.

The Intermediate Value Theorem tell us that there is a c in the interval [0,1] such that f(c) = k is lies between f(0) and f(1).

The Intermediate Value Theorem is a fundamental concept in calculus that states that given a continuous function f and two real numbers a and b, if k is a real number between f(a) and f(b), then there exists a real number c in the interval [a, b] such that f(c) = k.

In the specific case of [0,1], the Intermediate Value Theorem tells us that if k is a real number between f(0) and f(1), then there exists a real number c in the interval [0,1] such that f(c) = k. This means that for any value of k that falls between the values of the function at 0 and 1, there is a point in the interval [0,1] where the function takes on that value.

The fare for a 9-mile journey can be calculated using the formula Fare = £2.50 + £0.90 x miles. To find the fare for a 9-mile journey, we just need to substitute 9 for miles in the formula:

Fare = £2.50 + £0.90 x 9

Fare = £2.50 + £8.10

Fare = £10.60

So, the fare for a 9-mile journey would be £10.60.

It's important to understand how the formula works in order to correctly use it. The first part of the formula, £2.50, is a fixed cost that is added to the fare regardless of the distance traveled. This could represent things like the cost of hiring the taxi, the driver's time, and any other fixed expenses that the taxi company incurs.

The second part of the formula, £0.90 x miles, is the variable cost that is added to the fare depending on the distance traveled. This could represent things like the cost of fuel, wear and tear on the vehicle, and any other expenses that the taxi company incurs as a result of traveling a certain distance. By multiplying the distance traveled by the cost per mile, £0.90, the formula calculates the total variable cost for the journey.

When these two costs are added together, the formula gives the total fare for the journey. In this case, for a 9-mile journey, the total fare would be £10.60.

The flux of F coming out of the circle C is 126π.

The flux of a vector field, F, out of a surface, S, is given by the formula

Flux = ∮F •  n ds,

where n is a unit normal vector to the surface S.

In this case, the surface S is the circle C with radius 6 centered at the origin and the vector field F is given by F(x, y) = (7x, 11). We can use Green's Theorem to find the flux from the circle C. The equation for the circle is x2 + y2 = 36. Differentiating this equation with respect to x and y gives us the unit normal vector, n = (x/6, y/6).

Plugging these values into the flux formula, we get

Flux = ∮F •  n ds = ∮ (7x, 11) •  (x/6, y/6) ds

= ∮ 7x2/6 + 11y/6 ds

= (7/6) ∮ (x2 + y2) ds

= (7/6) * Area of C

= (7/6) * π * 36
