The table which represents a quadratic relationship is in option [tex]D[/tex].
What is quadratic relationship ?A quadratic relationship is a mathematical relation between two variables that follows the form of a quadratic equation.
Quadratic sequence [tex]=an^2 +bn+c[/tex]
So, According to the definition mentioned above if table follows the form of a quadratic equation then it is in quadratic relationship.
So,
To find out quadratic relationship,
We will find first difference in every table and then second difference (Second difference is the difference between the first difference).
We have,
Table A;
[tex]\left \begin{array}{ccccc}x& \ &f(x)&First\ Difference & Second\ Difference \\-2& &4&2-4=-2\\-1& &2&1-2=-1&-1+2=1\\0& \ &1&0.5-1=-0.5&-0.5+1=0.5\\1& &0.5&0.25-0.5=-0.25&-0.25+0.5=0.25\\2& &0.25&0.125-0.25=-0.125\\3& &0.125\end{array}\right[/tex]
So, In the above table we can see that second difference is not equal that means it is not in quadratic relationship.
Now,
Let Table D;
[tex]\left \begin{array}{ccccc}x& \ &f(x)&First\ Difference & Second\ Difference \\-2& &-23.4&\\-1& &-23.2&-23.2+23.4=-0.2&0.2-0.2=0\\0& \ &-23&-23+23.2=-0.2&0.2-0.2=0\\1& &-22.8&-22.8+23=-0.2&0.2-0.2=0\\2& &-22.6&-22.6+22.8=-0.2\\3& &-22.4&-22.4+22.6=-0.2\end{array}\right[/tex]
So, here in this table, we can see that second difference is equal that means it is in quadratic relationship.
Hence, we can say that the table which represents a quadratic relationship is in option [tex]D[/tex].

If you are currently 326 feet in the air, what is the angle of depression from you to your friend?
The angle of depression from you to your friend is 54.1°
Trigonometric ratios
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let θ represent the angle between me in air and my friend, hence:
tanθ = 326 / 450
θ = 35.9 degrees
The angle of depression = 90 - 35.9 = 54.1°
The angle of depression from you to your friend is 54.1°

Need help solving this linear equation
Answer: (-4, -7)
Step-by-step explanation: To solve this system of equations, we can use the substitution method.
To solve a system by substitution, we first need to isolate one of our variables. The problem is none of our variables has a coefficient of 1 or -1. In this situation, we have to look at our next best option.
In our first equation, add 2x to both sides to get
2y = -6 + 2x and just divide both sides by 2 to get y = -3 + x.
Now let's plug this value of y into our second equation.
So we have 3x + 7(-3 + x) = -61.
Simplifying from here:
3x - 21 + 7x = -61
10x - 21 = -61
10x = -40
x = -4
Since we know that x = -4, we can just plug a -4 into our equation that we created earlier to get y = -3 + (-4) or y = -7.
Since x = -4 and y = -7, our answer is the ordered pair (-4, -7).

Answer:

Step-by-step explanation:
The question is in the picture.
Answer:
x = 7[tex]\sqrt{3}[/tex]
Triangle area formula: base * height * 1/2
We are given:
Base - 14 cm
Height - x
Using the pythagorean theroem (a^2 + b^2 = c^2) we can figure out the height.
We are given:
Side a - 14 / 2 = 7 cm
Side b - the height (x)
Side c - 14 (it's an equilateral triangle)
Now, substitute the given values:
7^2 + x^2 = 14^2
49 + x^2 = 196
x^2 = 147
x = [tex]\sqrt{147}[/tex]
x = 7[tex]\sqrt{3}[/tex]
