Marcy is a 5-ft-5 in. She took measurements of both her own shadow. h=520 is the building's height.

Given that,

Marcy is a 5-ft-5 in. She took measurements of both her own shadow and that of the structure in order to determine its height.

We have to find what is the building's height, h.

Use the fact that 1 feet is equivalent to 12 inches to convert all measures to a single unit, inches.

We convert

MN=26×12=312 inches.

QR=3×12+3=36+3=39 inches.

PQ=5×12+5=60+5=65inches.

Since the Sun's rays that generate LN and PR are parallel, they are also parallel. the angles they make with the earth as a result are consistent:

∠N≅∠R

The Right Angle Congruence Theorem illustrates ∠M≅∠Q.

As a result, according to the Angle-Angle Similarity △LMN~△PQR

Calculate a ratio using the known lengths of the sides and the unknown length (height of the building).

PQ/QR=LM/MN

65/39=h/312

h=65×312/39

h=20280/39

h=520

Therefore, h=520 is the building's height.

If the sample size were to increase, and all other numbers remaining stays the same, then the standard error would be less.

Standard error is defined as the measures of the preciseness of an estimate of a population mean. It can be calculated by dividing the sample standard deviation by the square root of the sample size.

SE = SD / √n

where SE = standard error

SD = sample standard deviation

n = sample size

Increasing the sample size, n, while the samples remain the same(hence, the standard deviation will be the same), will result to smaller standard error.

The Ratios 5 : 3 and 17 : 12 does not form a proportion.

What is Proportion?

A Proportion, in mathematics, can be defined as when two ratios are set equal to each other.

Now, the given ratios are: 5 : 3 and 17 : 12

We can also write the ratios as: [tex]\frac{5}{3}[/tex] and [tex]\frac{17}{12}[/tex]

To determine, if they are a proportion, we can cross multiply and get the same answers on both the sides.

When we multiple, the numerator from the first by the denominator of the second, we get

5 * 12 = 60                             …(1)

Now, multiply the denominator from the first by the numerator of the second, we get

3 * 17 = 51                             …(2)

Since, (1) and (2) are not equal. Therefore the ratios does not form a proportion.

Define Perimeter of triangle

A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length.

Perimeter of Triangle = side1 + base + side2

Let, the shortest side of the triangle = x

The other side length is = 2x

and, the length of third side is = x + 16

given perimeter = 156 feet

We know, perimeter of triangle = a + b +c

where, 'a' and 'c' stands for sides of triangle

and, b stands for base

hence, the expression will be according to formula,

x + 2x + x + 16 = 156

solve for 'x'

4x + 16 = 156

4x = 156 - 16

x = 140/4

x = 35

2x = 2 * 35 = 70

x + 16 = 35 + 16 = 51

Therefore, the length of three sides will be 35 feet, 70 feet and 51 feet.

If a stick of length 60 inches is measured to be 63 inches long the the percent error will be 5% .

The Percent Error can be calculated by the formula

Percent Error = (measured value - actual value)/(actual value)  ×100

In the question ,

it is given that

the original length of the stick is 60 inches .

the measured length of the stick is 63 inches .

So, the measured value = 63 inches ,

actual value = 60 inches .

Substituting the measured values and actual value in the percent error formula , we get

Percent Error = (63-60)/60 × 100

= 3/60 × 100

= 1/20 × 100

= 100/20

√ x/4 + 4 is the inverse of the function f(x)=4x^2-16

What is inverse function?

In mathematics, the inverse function of a function f (also called the inverse of f) is a function that undoes the operation of f

Given  f(x)=4x²-16

Let f(x) = y

So we can say y =4x²-16

We will then make x the subject:

Since y = 4x²-16

4x² = y + 16

x² = y + 16/4

x = √ y/4 + 4

since x = f⁻¹(y)  = √ y/4 + 4

Thus  f⁻¹(x)  = √ x/4 + 4

Therefore, the inverse of f(x)=4x^2-16 is √ x/4 + 4

The sequence's 61st term is -972.

The sequence is -12 , -28 , -44.

The following arithmetic sequence is: -12, -28, -44, ..

Find the common difference between the succeeding and preceding terms.

         c.d = first term - second term

-28 - (-12) = -28 + 12 = -16

-44 - (-28) = -44 + 28 = -16

As a result, the distinction between the terms remains constant.

This is a mathematical sequence.

The formula for the nth term of an arithmetic sequence is:

an = a1 + (n - 1 ) d

Where,

an is the sequence's nth term.

a1 is the sequence's first term.

The common difference between terms is denoted by d.

-12, -28, -44 are the numbers in the given sequence.

By changing the values in the formula,

a1 = -12

d = -16

Substituting values,

an = -12 + (n - 1 )(-16)

an = -12 - 16n + 16

an = 4 - 16n

Substitute n = 61 to find the 61st term.

a61 = 4 - 16 x 61

a61 = 4 - 976

a61 = -972

As a result, the sequence's 61st term is -972.
