Answer:
The formula to calculate the area of a regular polygon is, Area = (number of sides × length of one side × apothem)/2, where the value of apothem can be calculated using the formula, Apothem = [(length of one side)/{2 ×(tan(180/number of sides))}].

A ball is hit from the ground. When that ball has traveled a horizontal distance of d meters, its height, h, in meters, can be modeled by the function (d) =-1/1125d2+d.
what is the horizontal distance from the point where the ball is hit to the point whitch ball lands on the ground.
Answers
Answer:
I'll assume the equation is h(d) = -(1/1125)d^2 + d
Please check, the (1/1125) term is disturbing.
Step-by-step explanation:
When the ball hits the ground, the height, h(d) is 0. We want the value of d, the distance the ball has travelled horizontally, that would give the function a value of 0.
h(d) = -(1/1125)d^2 + d
0 = -(1/1125)d^2 + d
(1/1125)d^2 - d = 0
Solve using the quadratic equation: I get 0 and - 1125 seconds. I conclude that the factor (1/1125) is incorrect, or some other error in the equation.
The horizontal distance from the point where the ball is hit to the point at which the ball lands on the ground is 1125.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
When the ball hits the ground, the height, h(d) is 0. We need to find the value of d, the distance the ball has traveled horizontally, which would give the function a value of 0.
Solve using the quadratic equation
h(d) = -(1/1125)d^2 + d
0 = -(1/1125)d^2 + d
(1/1125)d^2 - d = 0
(1/1125)d^2 = d
d = 1125
Thus, the horizontal distance from the point where the ball is hit to the point at which the ball lands on the ground is 1125.

Answers
Answer: Yes
Step-by-step explanation:
It can have angles of 90 degrees, 45 degrees, and 45 degrees.
Yes, a triangle in which at least two sides are equal. Since the two legs of the triangle are equal, which makes the corresponding angles are equal to each other.
What is the isosceles triangle?The Isosceles Right Triangle has one of the angles exactly 90 degrees and two sides, which are equal to each other.
Since the two sides are equal it makes the corresponding angle congruent.
An Isosceles triangle is a triangle in which at least two sides are equal. Since the two legs of the triangle are equal, which makes the corresponding angles are equal to each other.
Hence, Yes, a triangle in which at least two sides are equal. Since the two legs of the triangle are equal, which makes the corresponding angles are equal to each other.

Which of the following is true? there is a phase shift to the left. there is a phase shift to the right. the graph is reflected across the x-axis the graph is stretched horizontally. the graph is compressed horizontally.
Answers
Answer:
a. There is a phase shift to the left
Step-by-step explanation:
The correct statement for the graph of y = cos (x + pi/6) compared to the graph of y = cos(x) is given by: Option A: There is a phase shift to the left.
How does transformation of a function happens?The transformation of a function may involve any change.
Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.
If the original function is y = f(x), assuming horizontal axis is input axis and vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: [tex]y=f(x+c)[/tex]output, but c units earlier)Right shift by c units: [tex]y=f(x-c)[/tex] (same output, but c units late)Vertical shift:
Up by d units: f(x) + dDown by d units: y = f(x) - dStretching:
Vertical stretch by a factor k: [tex]y = k \times f(x)[/tex]Horizontal stretch by a factor k: [tex]y = f(\dfrac{x}{k})[/tex]For this case, the parent function y = cos(x) is transformed to make the function y = cos (x + pi/6)
Thus, there is left shift of the graph of the function y =cos(x).
The graphs of both functions (parent function in red color and transformed function in blue color) is given below.
Thus, the correct statement for the graph of y = cos (x + pi/6) compared to the graph of y = cos(x) is given by: Option A: There is a phase shift to the left.

In the following figure, the square ABCD is inscribed in the circle centered at point P. What is the area of the circle?
Answers
Answer:
[tex]A_{Circle} \approx 39.24\: units^2[/tex]
Step-by-step explanation:
Square ABCD is inscribed in a circle with center P such that BC = 5 units.
BD will be diagonal of the square as well as diameter of the circle.
[tex]BD = BC\times\sqrt 2[/tex]
[tex]\implies BD = 5\sqrt 2[/tex]
-> Diameter of the circle [tex](d) = 5\sqrt 2[/tex]
-> Radius of the circle [tex](r) = 2.5\sqrt 2=3.535\: units[/tex]
[tex]A_{Circle} =\pi(r)^2[/tex]
[tex]\implies A_{Circle} =3.14(3.535)^2[/tex]
[tex]\implies A_{Circle} =3.14(3.535)^2[/tex]
[tex]\implies A_{Circle} =39.2381465[/tex]
[tex]\implies A_{Circle} \approx 39.24\: units^2[/tex]
