Mathematics
1 answer:

Answer:

132 people bought balcony seats and 450 people bought ground seats.

Step-by-step explanation:

We want to solve the system of equations:

\left\{        \begin{array}{ll}            15b+10g=6480 \\            b+g=582        \end{array}    \right

We can solve this by using substitution. From the second equation, we can subtract <em>b</em> from both sides:

g=582-b

In the first equation, we can divide both sides by five:

3b+2g=1296

Substitute:

3b+2(582-b)=1296

Distribute:

3b+1164-2b=1296

Simplify:

b+1164=1296

Solve for <em>b: </em>

<em />b=132<em />

<em />

Using the modified equation again, substitute:

g=582-(132)

Evaluate:

g=450

Therefore, 132 people bought balcony seats and 450 people bought ground seats.

Use implicit differentiation to find the negative slope of a tangent to the circle x^2+y^2=16 at x=-2
SVETLANKA909090 [29]

Answer:

slope = - \frac{\sqrt{3} }{3}

Step-by-step explanation:

Differentiating implicitly with respect to x

2x + 2y \frac{dy}{dx} = 0

2y \frac{dy}{dx} = - 2x

\frac{dy}{dx} = - \frac{2x}{2y} = - \frac{x}{y}

\frac{dy}{dx} is the measure of the slope of the tangent

rearrange equation to find corresponding y-coordinate of x = - 2

y² = 16 - 4 = 12 = 2\sqrt{3} ⇒ y = ± 2\sqrt{3}

using x = - 2, y = - 2\sqrt{3}, then

\frac{dy}{dx} = - \frac{1}{\sqrt{3} } = - \frac{\sqrt{3} }{3}

enot [183]
916...the 9 is in the hundreds place so its value is 900
791...the 9 is in the tens place so its value is 90

900/90 = 10
so the 9 in 916 is 10 times bigger then the 9 in 791
