<h3>This curve passes the vertical line test, therefore it is a function.</h3>

<h3>The idea behind the vertical line test is that if you draw any vertical line, it has to intersect the curve only once. If there is more than 1 intersection, then it is not a function.</h3>

ps: This is a quadratic function of equation

$f(x) = - x {}^{2} + 4$

Find the surface area of the cylinder in terms of pi.<br><br> Height = 8 in<br> Diameter = 4in

irga5000 [103]

1) the area of the "side" of the cylinder is A1= pi (4 in).
2) the total area of the circular ends of the cyl. is A2 = 2 pi (2 in)^2 (since the radius of the cyl. is 2 in).

The desired total surface area is A = A1 + A2. Keep "pi;" do not substitute a numerical value for "pi."

What number goes in the box?<br> 2 ^ ( ) = (2^7 ÷ 2^9)^3

navik [9.2K]

Answer:

$x=-6$

Step-by-step explanation:

$(\frac{2^{7}}{2^{9}})^{3} \\(\frac{128}{512})^{3} \\(\frac{1}{4})^{3}\\(\frac{1}{4})*(\frac{1}{4})*(\frac{1}{4})\\\frac{1*1*1}{4*4*4} \\\frac{1^{3} }{4^{3} } \\\frac{1}{64} \\2^{x}=\frac{1}{64}\\log 2^x=log\frac{1}{64}\\x*(log(2))=log\frac{1}{64}\\x=\frac{log\frac{1}{64}}{log(2)} \\x=-6$
