Which is an exponential decay function?

Nikitich [7]

Answer:

$f(x)=\frac{3}{2}(\frac{8}{7})^{-x}$

Step-by-step explanation:

An exponential function of the form $f(x)=a(b)^x$ will decay if $0\:$

This implies that option A will not decay because $\frac{7}{4}\:>\:1$

Option B will not decay because $f(x)=\frac{2}{3}(\frac{4}{5})^{-x}\implies f(x)=\frac{2}{3}(\frac{5}{4})^{x}$ which implies that $b=\frac{5}{4}\:>\:1$

Option C can be rewritten to get: $f(x)=\frac{3}{2}(\frac{8}{7})^{-x}\implies f(x)=\frac{3}{2}(\frac{7}{8})^{x}$ ....This exponential function decays.

Option D will not decay because $-\frac{9}{2}\:$

What is the perimeter of a polygon with vertices at (−2, 1) , (−2, 7) , (1, 11) , (4, 7) , and (4, 1) ?

Sholpan [36]

Each edge is given by the distance formula, which is the Pythagorean Theorem. When one of the coordinates is the same, we can shortcut that.

A(−2, 1) , B(−2, 7), C(1, 11), D(4, 7), E(4, 1)

$AB=7-1=6$

$BC=\sqrt{(1 - -2)^2 + (11-7)^2}=5$

$CD=\sqrt{(4 - 1 )^2 + (11-7)^2}=5$

$DE=7-1=6$

$EA= 4 - -2 = 6$

$\textrm{perimeter} = 6+5+5+6+6=28$

Answer: 28
