True or False? A circle could be circumscribed about the quadrilateral below.
O A. True
B. False
A circle could be circumscribed about the quadrilateral is true.
What is Quadrilateral?A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles. It is formed by joining four non-collinear points
If opposite angles of a quadrilateral add to 180 then it is called a cyclic quadrilateral and a circle can be inscribed in it.
Here, the opposite sides are 115 and 65
115+65=180
The other opposite sides have 90 and 90
90+90=180, which means that it is true that a circle can be circumscribed about the quadrilateral above.
Hence, A circle could be circumscribed about the quadrilateral is true.

A golf ball, thrown upwards, rises at a speed of v metres per second.
The ball reaches a maximum height of h metres.
h is proportional to the square of v.
When v = 10, h = 8
Work out the maximum height reached by the golf ball when v = 45
Answer:
162 metres
Step-by-step explanation:
Since h is proportional to the square of v, we know that their ratio must be constant, so [tex]v_1^2/h_1 = v_2^2/h_2[/tex] where v1 and v2 are velocities and h1 and h2 are their respective heights.
Since we are given that v = 10 and h = 8, we can set v1 = 10 and h1 = 8 and since we are trying to find the height for v = 45, we can set v2 = 45. Inputting these values into the equation and solving, we get
10^2/8 = 45^2/h2
h2 = 45^2/(10^2/8) = 162 metres

It takes 13 hours and 15 minutes to paint longer walls of the houseStep-by-step explanation:
Given:Rectangular house. Painting of the longer walls takes 8 hours longer than painting shorter walls.Total time to paint is 18.5 hours.Let the length of shorter sides be x and longer sides be y.
Then we have the system:
y = x + 8x + y = 18.5Solve it by substitution:
x + x + 8 = 18.52x + 8 = 18.52x = 10.5x = 10.5/2x = 5.25Find the value of y:
y = 5.25 + 8 = 13.25 hours or 13 hours and 15 minutesShorter one be x
longer one=x+8
Total time=18.5hSo
x+x+8=18.52x+8=18.52x=18.5-82x=10.5x=10.5/2x=5.25hoursTime required for longer side
5.25+813.25hours

(5√3-√27)^2
How do you prove this is an integer?
Expand the square. Remember that
(a - b)² = a² - 2ab + b²
With a = 5√3 and b = √27, we have
(5√3 - √27)² = (5√3)² - 2 (5√3) √27 + (√27)²
… = 25•3 - 10√81 + 27
… = 75 - 10√(9²) + 27
… = 102 - 10•9
… = 102 - 90

An event that may occur in the game is you roll a and get a tail.
The probability that he will roll a 5 and get a head is 1 / 12.
What is the probability?
Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability that he will roll a 5 and get a head = (Number of sides with a 5 / number of sides in a cube) x (number of sides with a head / number of sides in a coin)
1/6 x 1/2 = 1 / 12.

Answer:
Step-by-step explanation:
As it is a second order equation, it means that it has two possible answers and they are [tex]x_1[/tex] and [tex]x_2[/tex].
The famous quadratic formula for solving any second order equation is the following:
[tex]x_{1} = \frac{-b + \sqrt{b^2 - 4 ac}}{2a}\\x_{2}=\frac{-b - \sqrt{b^2 - 4 ac}}{2a}[/tex]
Where a is the coefficient of [tex]x^2[/tex], b is the coefficient of x, and c is the free term. In other words,
[tex]a = 3\\b=4\\c=-2[/tex]
as the equation should be in the following form:
[tex]a x^2 + bx+c = 0[/tex]
Therefore the possible answer should be the following,
[tex]\frac{-4 + \sqrt{4^2 - 4*3*(-2)}}{2*3}=\frac{-4 +\sqrt{16 + 24}}{6} =\frac{-4 + \sqrt{40}}{6}=\\ \frac{-4 + \sqrt{4*10}}{6} = \frac{-4 + 2\sqrt{10}}{6}[/tex][tex]\frac{2*(-2 + \sqrt{10})}{2*3} = \frac{-2 + \sqrt{10}}{3}[/tex]

In this exercise, we would evaluate the given expressions by factorizing the function u(x) as follows:
u(x) = x⁵ – x⁴ + x²
u(x) = x²(x³ – x² + 1)
Rewriting the expressions as a fraction, we have:
[tex]\frac{u(x)}{v(x)} = \frac{x^2(x^3 - x^2 + 1)}{-x^2}\\\\\frac{u(x)}{v(x)} = -(x^3 - x^2 + 1)\\\\\frac{u(x)}{v(x)} = -x^3 + x^2 - 1[/tex]
