Height of tree is given by the distance multiplied by the tangent of the angle of elevation:
Height = 30*tan(40) = 30(0.8391)=25.17 ft
$2.00 + 0.75 + 0.40 + 0.05 + 0.03 = $3.33
The name Quadratic<span> comes from "quad" meaning square, because the variable gets squared (like x</span>2<span>). However, it is important to not that an expression is only quadratic if and only if the highest degree of a term is 2. Therefore, the quadratic equations from the pool of choices would be as follows:
</span><span>3x^2 + 5x - 7 = 0
</span><span>5x^2+ 15x = 0
</span><span>x^2 - 4x = 4x + 7</span>

Using limits, the polynomial that has an even degree and a negative leading coefficient is:
Polynomial going down from the left and passing through the point negative 7 comma 0 and going to a local minimum and then going up through the point negative 3 comma 0 and 0 comma 8 to a local maximum and then down to the right through the point 4 comma 0.
<h3>What is a limit?</h3>
A limit is given by the value of function f(x) as x tends to a value.
In this problem, to find the polynomial, we have to find the limits as x goes to infinity, hence:
![\lim_{x \rightarrow -\infty} f(x) = [tex]\lim_{x \rightarrow -\infty} -a x^n](https://tex.z-dn.net/?f=%5Clim_%7Bx%20%5Crightarrow%20-%5Cinfty%7D%20f%28x%29%20%3D%20%5Btex%5D%5Clim_%7Bx%20%5Crightarrow%20-%5Cinfty%7D%20-a%20x%5En)
Since n is even, we have that:
Since it goes down to the left and down to the right, hence the function is:
Polynomial going down from the left and passing through the point negative 7 comma 0 and going to a local minimum and then going up through the point negative 3 comma 0 and 0 comma 8 to a local maximum and then down to the right through the point 4 comma 0.
