Ok the ladder and the ground will make a right triangle/right angle. This is because the ground is flat, the wall is straight and only the ladder is leaning/slanted. I hope this helps.

Suppose the function D(p)=1500-25p represents the demand for hot dogs, whose price is p, at a baseball game. Find the domain of

TiliK225 [7]

The function is given by

$\\ \tt\hookrightarrow D(p)=1500-25p$

Price must be greater than 0

$\\ \tt\hookrightarrow 1500-25p\geqslant 0$

$\\ \tt\hookrightarrow 1500\geqslant 25p$

$\\ \tt\hookrightarrow p\leqslant 60$

Now

$\\ \tt\hookrightarrow D_f\in (-\infty,60]$

X^2+2x+9=0 please?!<br>

Nadusha1986 [10]

Answer:

D

Step-by-step explanation:

Given a quadratic equation in standard form : ax² + bx + c = 0

We can solve for x using the quadratic formula

x² + 2x + 9 = 0 ← is in standard form

with a = 1, b = 2 and c = 9

x = ( - 2 ± $\sqrt{2^2-(4(1)(9)}$ ) / 2

= ( - 2 ± $\sqrt{4-36}$ ) / 2

= (- 2± $\sqrt{-32}$ ) / 2)

= (- 2 ± $\sqrt{16(2)(-1)}$ ) / 2

= ( - 2 ± 4i $\sqrt{2}$ ) / 2

= $\frac{-2}{2}$ ± $\frac{4i\sqrt{2} }{2}$

= - 1 ± 2i $\sqrt{2}$ → D
