Answer: Radius = 5.33

Diameter = 10.66

Area = 89.3

Step-by-step explanation:

Circumference = 2πr

33.5 = 2πr

r = 33.5 / 2π

Diameter = 2r

Area = r²π

Area = 5.33²π

Thus, t has a greater value than s for the co-ordinates (s, -1) and (t, 3).

How to analyze points of an axis for a two dimensional entity?
We can use the fact that both points on the x-axis to compare the values of s and t for the provided parallelogram. As a result, each point that is closest to the x coordinate reflects a higher value than its equivalent counterparts.

Given, the co-ordinates of the parallelogram are: (-2, 3), (s, -1), (0, -1),
(t, 3).
Also, the co-ordinates of the parallelogram are also shown in the figure below.
To compare for the values of s and t for the given parallelogram,
we can analyze that both s and t represent points on the x-axis, therefore any point that stands rightmost with the x co-ordinate represents a higher value than the corresponding counterparts.
Therefore, t has a greater value than s for the co-ordinates (s, -1) and (t, 3), since t is on the right side from s.

For a quadratic [tex]ax^2+bx+c[/tex], the sign of its determinant, given by

[tex]\Delta = b^2 - 4ac[/tex]

"determines" the nature of its roots. In particular, if [tex]\Delta<0[/tex], then the quadratic has two distinct non-real roots.

Now, we have

[tex]3z^2 - 9z = n-3 \implies 3z^2 - 9z - (n-3) = 0[/tex]

with determinant

[tex]\Delta = (-9)^2 - 4\cdot3(n-3) = 117 - 12n[/tex]

Solve for [tex]n[/tex] such that [tex]\Delta<0[/tex].

[tex]\Delta = 117 - 12n < 0 \implies 12n > 117 \implies n > \dfrac{117}{12} \\\\ ~~~~ \implies \boxed{n > \dfrac{39}4}[/tex].

The graph of |y| = x/2

The graph of y = |x|

The graph of -1/2 |y| = x

Answer: 19 cm

Step-by-step explanation:

Substituting into the formula for the area of a trapezoid,

[tex]\frac{1}{2}(x-4)(x+4+x+9)=99\\\\\frac{1}{2}(x-4)(2x+13)=99\\\\(x-4)(2x+13)=198\\\\2x^2 +5x-250=0\\\\(2x+25)(x-10)=0\\\\x=-12.5, 10[/tex]

However, as x must be positive (since length must be positive), x=10. This means the length of the longer base is 19 cm.

The two lines are neither parallel nor perpendicular.

What is condition for perpendicular, parallel?

if two given lines are parallel, perpendicular, or neither, we need to compare their slopes. For this, we need to make sure that their equations are in the form y = mx + b. This represents the equation of a straight line in the slope-intercept form, where m is the slope and b is the y-intercept.

If the given lines have the same slope, they’re parallel to one another. On the other hand, if they have slopes that are opposite reciprocals, i.e., the slopes have opposite signs and are flipped fractions of one another, they are perpendicular to each other. Else, they are neither.

The given lines are

- 3x + 6y = 12 or, y = (1/2)x + 2 ... (1)

y = - 3x + 10 ... (2)

The gradient of the lines (1) and (2) are 1/2 and (- 3) respectively.

Since the gradients are not equal, the lines are not parallel and also since (1/2) × (- 3) ≠ - 1, the lines are not perpendicular to each other.

Hence we can conclude that the given two lines are neither parallel nor perpendicular.

The dimensions of your mowing plot if x = 13 meters is;

Length = 31 meters

Width = 36 meters

We are told that Your plot has a length which is five more than two times x and the width is three less than three times x

This means that, the length given as words is "5 more than 2 times x" and the width given as words is "3 times x minus 3"

The expression for length would be  2x + 5

The expression for width would be 3x - 3

Now, if x = 13 meters, then we see that;

Length = 2(13) + 5 = 31 meters

Width = 3(13) - 3 = 36 meters

A function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output.

Here the domain of the relation is {3,x,9,5}.

The given relation is a function only if x not takes any of the value 3, 9 or 5.

So, option B is correct.

Case: Secant secant theorem

Secant-Secant Power Theorem: If two secants are drawn from an external point to a circle, then the product of the measures of one secant's external part and that entire secant is equal to the product of the measures of the other secant's external part and that entire secant

The percent of people that were completely satisfied (%PS) can be calculated with the formula:

Where PS is the number of persons that were completely satisfied and TP is the total number of persons, in this case, the total number of persons is the sum of each number of persons from each category:

And as we can see from the figure, the number of completely satisfied people is 1100, then the percent of people that were completely satisfied is:

The percent of people that were completely satisfied is 55%

You just have to divide 1100 by the total people which is 2000, and then just multiply by 100, and that's it

The 30-60-90 ratio is a special right triangle that always has angles with measures: 30º, 60º, and 90º. Its side lengths have also the same relationship one with another.

For any 30-60-90 the ratio is as follows:

The side opposite to the 30º angle has length: z

The side opposite to the 60º angle has a length z√3

The side opposite to the 90º angle has a length: 2z

Following these ratios, you can determine the side lengths of the triangle.

The measure opposite to the 60º angle is z√3 = 9√3 → From this we can determine the value of z, which is z=9

Once we know the value of z, we can calculate the values of the sides opposite to the other angles.

The side opposite to the 30º angle is y= z= 9

The side opposite to the 90º angle is x= 2z= 2*9 = 18

Any integer that cannot be divided into twos is considered an odd number. Five computers, for instance, cannot be arranged in pairs only. 5 is therefore an odd number.

An even number is one that can be divided by two and leaves residue of zero. The even numbers include 2, 4, 6, 8, 10, and so on. Let's say, for instance, that you have ten chocolates. There are two groups of these chocolates that each include five chocolates. Ten is therefore an even number.

An even number is produced by adding two even numbers. In this case, 12 + 8 equals 20.

Odd numbers are created by adding odd numbers to even numbers. For example, 6 + 7 equals 13.

The outcome of adding two odd numbers is an even number. For an instance, 15 + 11 = 26.

Using the uniform distribution, it is found that:

a) The probability that the friend is between 10 and 20 minutes late is of 1/3.

b) There is a 30% probability that the friend will arrive within 9 minutes.

The uniform has two bounds, a and b, and each outcome of the distribution is equally as likely.

From the image given at the end of the answer, the bounds are given as follow:

a = 0, b = 30.

The probability of finding a value between c and d in the distribution is:

[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]

Hence, the probability that the friend is between 10 and 20 minutes late is given as follows:

P(10 <= X <= 20) = (20 - 10)/(30 - 0) = 1/3.

The 30th percentile of the distribution, which is what item b is asking, is given as follows:

Step-by-step explanation:

If 60 songs are played in 3 hours, 80 songs in 4 hours, and 120 songs in 6 hours, you want to know the number played in 5 hours.

Considering the rate of change of songs per hour, we find ...

  hours 3-4: 80-60 = 20 songs, over the 1-hour period

  hours 4-6: 120 -80 = 40 songs, over the 2-hour period

It appears that the number of songs being played is steady at 20 songs per hour. Then 5×20 = 100 songs were played in 5 hours.

The slope of a line from given points (19,-16), (-7, -15) is - 1/26

Slope :

In Mathematics, Slope of a line defined as the direction of the line and the change in y-coordinate with respect to x - coordinate. Slope of a line is denoted by 'm'

The formula for slope of a line which passes through the points (x₁, y₁) and (x₂, y₂) is given by Slope (m) =  (y₂– y₁)/(x₂ – x₁)

Here, we have pair of points (19,-16), (-7, -15)

Take (x₁, y₁) = (19,-16) and (x₂, y₂) = (-7, -15)

Slope (m) = [-15 -(-16) ] / [ -7 -19 ]

= [ - 15+16] / [ -26 ]  

= [ 1 ] / [ -26 ]  

= - 1/26

Therefore,

The slope of line from given points (19,-16), (-7, -15) is - 1/26
