Now,
Here are four ordered pairs that relate the side length of a pentagon to the perimeter of the pentagon:
⇒ (1, 5) (2, 10) (3, 15) (4, 20)
Hence, In each pair, the first number represents the side length of the pentagon, and the second number represents the perimeter of the pentagon.
And, If you add 1 to the side length in each pair, you'll see that the perimeter increases by 5, just as Fernando learned in math class.

13 cm
8°
Answer:
37.98°
Step-by-step explanation:
You want the value of θ in a right triangle with a hypotenuse of 13 cm and a side opposite the angle of 8 cm.
SineThe sine relation is ...
Sin = Opposite/Hypotenuse
In this figure, that means ...
sin(θ°) = (8 cm)/(13 cm)
The value of θ is found using the arcsin function:
θ° = arcsin(8/13) ≈ 37.98°
__
Additional comment
You will note the calculator mode is set to DEGrees.
The inverse function of the sine function is called the "arcsine" function. It is represented on most calculator keypads using a -1 exponent. (-1 is usually used with a function name to signify the inverse function. Here, the inverse sine function gives "the angle whose sine is ...".)
Typical units used for angles are degrees, radians, and gradians. The number that is the argument of the inverse sine function is a "pure number" with no units. If you find your calculation causes it to have units, then you need to check your work. (Here the units of cm in numerator and denominator cancel, leaving the unitless value 8/13.)

solve this triangle. Round to the nearest tenth
The missing measures in the triangle are given as follows:
m < F = 111.4º, m < D = 28.6º, f = 35.1.
What is the law of sines?Suppose we have a triangle in which:
Side with a length of a is opposite to angle A.Side with a length of b is opposite to angle B.Side with a length of c is opposite to angle C.The lengths and the sine of the angles are related as follows:
[tex]\frac{\sin{A}}{a} = \frac{\sin{B}}{b} = \frac{\sin{C}}{c}[/tex]
Considering the triangle in this problem, the relation is given as follows:
sin(D)/18 = sin(40º)/24.2.
Hence the measure of angle D is obtained as follows:
sin(D) = 18 x sine of 40 degrees/24.2
sin(D) = 0.4781
m < D = arcsin(0.4781)
m < D = 28.6º.
The sum of the internal angle measures of a triangle is of 180º, hence the measure of angle F is obtained as follows:
m < F + 40 + 28.6 = 180
m < F = 180 - (40 + 28.6)
m < F = 111.4º
Then the length f is obtained as follows:
sin(111.4º)/f = sin(40º)/24.2
f = 24.2 x sine of 111.4 degrees/sine of 40 degrees
f = 35.1.

3. Use the relationship between 21 and 25 to decide whether the top and middle
shelves are parallel. (2 points)
Answer:
The top and middle shelves are parallel.
Step-by-step explanation:
<1 and <5 are corresponding angles.
When two lines are cut by a transversal such that corresponding angles are congruent, the lines are parallel.
If angles 1 and 5 are congruent, the shelves are parallel.
We are given m<5 = 60°.
Also, m<2 = 120°.
Angles 1 and 2 are a linear pair and are supplementary.
The measures of angles 1 and 2 add to 180°.
m<1 + m<2 = 180°
m<1 + 120° = 180°
Subtract 120° from both sides.
m<1 = 60°
m<1 = m<5 = 60°
Since angles 1 and 2 have the same measure, 60°, angles 1 and 2 are congruent.
Answer: The top and middle shelves are parallel.

Given the polynomial f(x)=3x3-4x2-3x-1, what is the smallest positive integer a such that the intermediate value theorem guarantees a zero exist between zero and a
The smallest positive integer a that satisfies the conditions of the problem is a = 2.
The Intermediate Value Theorem states that if a function f(x) is continuous on the interval [a, b] and takes on values f(a) and f(b) at the endpoints a and b, respectively, then for any value c between f(a) and f(b), there exists at least one value x in the interval [a, b] such that f(x) = c.
In this problem, we are asked to find the smallest positive integer a such that the Intermediate Value Theorem guarantees a zero exists between 0 and a for the polynomial f(x) = 3x³ - 4x² - 3x - 1.
To find this value of a, we need to evaluate f(0) and f(a) and look for a value of a such that f(0) and f(a) have opposite signs. This will guarantee the existence of a root of f(x) between 0 and a.
Evaluating f(0), we get:
f(0) = 3(0)³ - 4(0)² - 3(0) - 1 = -1
To find f(a), we need to solve for a using the equation f(a) = 0. We can use a numerical method, such as the Newton-Raphson method or the bisection method, to find the root of f(x) = 0. Using a calculator or a computer program, we find that f(a) = 0 for a ≈ 1.353.
Since f(0) = -1 and f(a) = 0 have opposite signs, the Intermediate Value Theorem guarantees the existence of at least one zero of f(x) between 0 and a = 1.353. Therefore, the smallest positive integer a that satisfies the conditions of the problem is a = 2.

The length of each side of the square is about
units, and the length of its diagonal is about
units.
Answer:
19.8 units
Step-by-step explanation:
From the diagram attached, to find the length of side AB, we need to use Pythagoras theorem on the right triangles. We can see that AB is the base of the two right triangle.
For the first right triangle with hypotenuse of 13 and height of 12, let x be the base, therefore using hypotenuse:
13² = 12² + x²
169 = 144 + x²
x² = 169 - 144
x² = 25
x = √25 = 5
For the second right triangle with hypotenuse of 15 and height of 12, let y be the base, therefore using hypotenuse:
15² = 12² + y²
225 = 144 + y²
y² = 225 - 144
y² = 81
y = √81 = 9
The length of AB = x + y = 9 + 5 = 14 unit
Since for a square all the sides are equal, therefore the length of each side of the square ABCD is 14 units.
In triangle ADC, the hypotenuse = AC, AD = DC = 14 unit. Using Pythagoras:
AC² = AD² + DC²
AC² = 14² + 14²
AC² = 196 + 196 = 392
AC = √392 = 19.8
The length of its diagonal is about 19.8 units

x^2 + 2x − 4 | 5x^4 − 2x^3 − 7x^2 − 39
Evaluating the division, we have
5x^2 - 12x + 37
x^2 + 2x − 4 | 5x^4 − 2x^3 − 7x^2 − 39
5x^4 + 10x^3 - 20x^2
---------------------------------------
-12x^3 + 13x^2 - 39
-12x^3 - 24x^2 - 48
---------------------------------------
37x^2 + 9
37x^2 + 74x - 148
---------------------------------------
-74x + 157
Hence, the quotient is 5x^2 - 12x + 37

A small liberal arts college in the Northeast has 200
freshmen. Eighty of the freshmen are education majors. Suppose fifty freshmen are randomly selected (without replacement).
Step 1 of 2 : Find the expected number of education majors in the sample. Round your answer to two decimal places, if necessary.
The expected number of education majors in the sample is 20.
Probability calculationSince 80 out of 200 freshmen are education majors, the probability of randomly selecting an education major from the population is:
P(edu major) = 80/200 = 0.4
To find the expected number of education majors in a sample of 50 freshmen, we can use the formula for the expected value of a discrete random variable:
E(X) = n x p
Substituting the given values, we get:
E(X) = 50 x 0.4 = 20
Therefore, the expected number of education majors in a sample of 50 freshmen is 20.
