PLS ANSWER ITS URGENT

Answer:

The length of the ramp must be at least 14.71 feet

Step-by-step explanation:

Given

$BC = 2.3ft$

$\theta = 9^\circ$

<em>See attachment for complete figure</em>

Required

Length of the ramp (z)

To do this, we consider sin of angle A ( $\theta$ ).

So, we have:

$sin\theta = \frac{Opposite}{Hypotenuse}$

This gives:

$sin(9)= \frac{2.3}{z}$

Make z the subject

$z= \frac{2.3}{sin(9)}$

$z = \frac{2.3}{0.1564}$

$z = 14.71 ft$

<em>The length of the ramp must be at least 14.71 feet</em>

(PARABOLA? BRAINLIEST + 20 POINTS) A building has an entry the shape of a parabolic arch 22 ft high and 28 ft wide at the base.

Keith_Richards [23]

Check the picture below.

$\bf ~~~~~~\textit{parabola vertex form} \\\\ \begin{array}{llll} y=a(x- h)^2+ k\qquad \leftarrow \textit{let's use this one}\\\\ x=a(y- k)^2+ h \end{array} \qquad\qquad vertex~~(\stackrel{}{ h},\stackrel{}{ k}) \\\\[-0.35em] \rule{34em}{0.25pt}$

$\bf \begin{cases} h=0\\ k=0 \end{cases}\implies y=a(x-0)^2+0 \\\\\\ \textit{we also know that } \begin{cases} x=14\\ y=-22 \end{cases}\implies -22=a(14-0)^2+0 \\\\\\ -22=a(14)^2\implies -22=196a\implies \cfrac{-22}{196}=a\implies -\cfrac{11}{98}=a \\\\[-0.35em] ~\dotfill\\\\ y=a(x-0)^2+0\implies \boxed{y=-\cfrac{11}{98}x^2}$
