Use the diagram to solve for segments SW and WQ. Show your work and/or explain how you determined the answer

Minchanka [31]

The intersecting chords theorem states that whenever two chords intersect, the product of their pieces is constant.

So, in this case, we have

$\overline{RW}\cdot\overline{WP}=\overline{SW}\cdot\overline{WQ}$

Plugging your values, we have

$8\cdot 9 = 6x \cdot 12x \iff 72=72x^2 \iff x^2=1$

This equation has solutions $x=\pm 1$ , but we can't choose $x=-1$ , because it would lead to

$\overline{SW}=-6,\quad\overline{WQ}=-12$

So, the only feasible solutions is $x=1$

Which expression represents the perimeter of the rectangle with a width of 4x+3 and legnth of 2x?

slavikrds [6]

P = 2L + 2W
P = 2(2x) + 2(4x + 3)
P = 4x + 8x + 6
P = 12x + 6

The correct response would be D. 12x + 6.

Find all of the critical points of p (t). p (t) = t 2 + 5t + 6.

svp [43]

Please, use " ^ " to denote exponentiation: p(t) = t^2 + 5t + 6.

To find the critical points, differentiate p(t) with respect to t, set the result = to 0, and then solve the resulting equation for t:

p '(t) = 2t + 5 = 0

Solving for t: 2t = -5, and so t = -5/2. (-5/2, p(-5/2)) is the critical point. That evaluates to (-5/2, -0.25). This happens to be the vertex of a parabola that opens up.

the fire hydrant sits 72 feet from the base of a 125-foot buiding. Find the ANGLE OF ELEVATION from the fire hydrant to the top

PSYCHO15rus [73]

Answer:

60°

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationship between angles and sides in a right triangle. Here, we're given the side Adjacent and the side Opposite the angle of interest. This makes it appropriate to choose the relation ...

Tan = Opposite/Adjacent

For our angle of elevation α, this means ...

tan(α) = 125/72

α = arctan(125/72) = 60.058°

α ≈ 60°

The angle of elevation is about 60°.
