In order to identify if the triangles are similar, you first take into account the rect angle of the triangles. Form there you can notice that side ON in the bigger triangle, is similar to the side as RQ in the little one.
So, you calulate the proportion between sides ON and RQ, just as follow:
[tex]\frac{ON}{RQ}=\frac{8cm}{4\operatorname{cm}}=2[/tex]Then, the proportion of those sides is 2. This proportion must be the same for the other similar sides of both traingles, in order to conclude that the triangle are similar.
[tex]\frac{PN}{QS}=\frac{14\operatorname{cm}}{7\operatorname{cm}}=2[/tex][tex]\frac{PO}{RS}=\frac{12\operatorname{cm}}{6\operatorname{cm}}=2[/tex]Hence, the triangles are similar

y= -6x^{2} -36
what would it be in vertex from
The vertex form of a parabola is represented by the equation y = -6 (x-0)² -36 -0.
What is a vertex form?
And this equation gives you the vertex of a parabola. h is removed from and k is inserted in the vertex form equation. We can calculate h and k from the equation. The value of h is -b/2a. It is an alternate way of writing out the vertex form. In vertex form, we use the process of completing a square. A quadratic function can also be easily solved algebraically in the vertex form (if it has a solution). Completing the square, also known as converting a quadratic function from standard form to vertex form, is the first step in solving an equation.
The given equation is y = -6x² -36
So, a= -6, b = 0, c = -36
The general formula for the vertex form is given by
y = a[x - (-b/2a))² + c - b²/4a
y = -6((x - (-0/2(-6)))² + -36 - 0²/4(-6)
y = -6 (x-0)² -36 -0
Therefore, the vertex form is y = -6 (x-0)² -36 -0.

Given:
(sinx + 1)(2sin²x - 3sinx - 2) = 0
sinx + 1 = 0
sinx = -1
Take the arcsin of both-side
x = sin⁻' (-1)
x = -90= -90 + 360 = 270 = 3π / 2
x =3π / 2
Similarly,
2sin²x - 3sinx - 2 = 0
let y = sinx
2y² - 3y - 2 = 0
Factorising the above;
2y² - 4y + y - 2 = 0
2y(y-2) + 1(y-2) = 0
(2y+1)(y-2) = 0
Put sin x back in for y so we can see what it's really supposed to be.
(2sinx + 1 )(sinx -2) = 0
Either one of the terms 2sin x + 1 or sin x - 2 can be 0 for this equation to be true. Let's solve each of them separately.
2sinx + 1 = 0
2sinx = -1
sinx = -1/2
Take the arcsin of both-side.
x= sin⁻' (-1/2)
x = - 30 = -30+360 = 330 ,
x = 7π /6 or 11π/6
Therefore, the correct option is B. x= 3π / 2 , 7π /6 , 11π/6

What is meany by the term exponent?A number's exponent signifies how many times a number has been multiplied by itself. For instance, 2×2×2×2 can be written as 2⁴, because 2 is multiplied on its own four times. In this case, 2 is referred to as the "base," and 4 is referred to as the "exponent" as well as "power." In general, xⁿ denotes that x has been multiplied by itself n times.For the given question;
The three expressions are given as;
a: 20(1.1ˣ) ...1
b: 20(1.1⁻¹)⁻¹ˣ
Simplifying as;
= 20(1.1⁻¹⁽⁻¹ˣ⁾)
= 20(1.1ˣ) ....2
c: 20(1.1¹/⁵)⁵ˣ
Simplifying.
= 20(1.1¹/⁵⁽⁵ˣ⁾)
= 20(1.1ˣ) ....3
So, a = b = c
Thus, all three expressions are equivalent to each other.

the company will make a profit when the revenue is greater than the cost
therefore
the value of x must be greater than 1,250

The point of maxima of any function can be known by equating its derivative to zero. The rocket will take 1.5 sec to reach the maximum height and the maximum height is 27 feet.
What is differentiation?The differentiation of a function is defined as rate of change of its value at a point. It can be written as g'(x) = (g(x + h) - g(x)) /(x + h - x).
Its geometric aspect is the slope of the function at a given point.
Given that,
Initial height of the launching pad is 4 feet,
Initial velocity of rocket is 48 feet/sec,
Height of the rocket as a function of time, h(t) = -16t² + 48t + 3
In order to find the time for maximum height equate h'(t) = 0 as follows,
-32t + 48 = 0
⇒ t = 48 / 32
⇒ t = 3 / 2
⇒ t = 1.5
To find the maximum height find h(t) for t = 1.5 as follows,
h(1.5) = -16 × 1.5² + 48 × 1.5 + 3
= -36 + 60 + 3
= -36 + 63
= 27
Hence, the time taken by the rocket to reach the maximum height is 1.5 sec and the maximum height reached is 27 feet.

In first question, the value of Angle 1 is 42 and the value of Angle 2 is 48.
In second question, the value of Angle 1 is 11, Angle 2 is 159, Angle 3 is 11, Angle 4 is 165.
In the given question, have two question.
Firstly solving the question 1.
1) In question 1 we have to find the measure of Angle 1 and Angle 2.
There is figure. In this figure we can see that it is a right angle.
The right angle is of 90 degree.
So x+x+6=90
Simplifying the expression
2x+6=90
Subtract 6 on both side
2x+6-6=90-6
2x=84
Divide by 2 on both side
2/2x=84/2
x=42
The value of x is 42.
Now The value of Angle 1 is 42.
Now finding the Angle 2.
Angle 2 is x+6 and x=42
So
=42+6
=48
Hence, the value of Angle 2 is 48.
2) In this question we have to find the value of Angle 1,2,3 and 4.
To solve this question we using the straight line angle.
As we know that the angle of straight angle is 180.
So from the figure we can see that
∠2+∠3=180
As we know that ∠3=2x+3
So ∠2+2x+3= 180
Subtract 3 on both side
∠2+2x+13−13=180−13
∠2+2x=167................Equation 1
As we can also know from the figure that
∠1+∠4=180
And ∠1=x+7
x+7+∠4=180
Subtract 7 on both side
x+7+∠4−7=180−7
∠4+x=173.......................Equation 2
From the corresponding angle theorem we know
∠1=∠3
2x+3=x+7
Subtract 3 on both side
2x+3−3=x+7−3
2x=x+4
Subtract x on both side
2x−x=x+4−x
x=4
Now putting the value of x in Equation 1
∠2+2x=167
∠2+2×4=167
∠2+8=167
Subtract 8 on both side
∠2+8−8=167−8
∠2=159
Now putting the value of x in Equation 2
∠4+x=173
∠4+4=173
∠4+4=173
Subtract 4 on both side
∠4+4−4=173−8
∠4=165
∠3=2x+3
∠3=2×4+3
∠3=8+3
∠3=11
∠1=x+7
∠1=4+7
∠1=11
Hence, the value of Angle 1 is 11, Angle 2 is 159, Angle 3 is 11, Angle 4 is 165.

[tex]\frac{3}{7+9}=\frac{3}{16}=0.1875[/tex]write interval notation x>2 or -x >6
To answer this question, we need to have into account the following:
1. In the context of interval notation, the word "or" can be represented by the symbol "U".
2. We need to rearrange the inequality -x > 6 in a way that we have positive x.
We can proceed as follows:
Case x>2[tex]x>2\Rightarrow(2,\infty)[/tex]We can express the inequality in this way because it expresses all of the values greater than 2, and these values tend to the positive infinity. We have parenthesis here since the values are not equal to 2 (only greater than 2).
Case -x > 6If we multiply both sides of the inequality by -1, we need to reverse the direction of the inequality as follows:
[tex]\begin{gathered} -1(-x>6)=-1(-x)<-1(6) \\ x<-6 \end{gathered}[/tex]Now, we have all of the values less than -6, not equal, and because of this, we have to use parenthesis:
[tex]x<-6=(-\infty,-6)[/tex]Therefore, we can say that:
