Find f(x) and g(x) so that the function can be described as y = f(g(x)). y = nine divided by square root of quantity five x plus

katrin [286]

$y=\frac{9}{\sqrt{5x+5}}$
hmm, seems that we can say that the square root thing is the g(x)

I would say
$f(x)=\frac{9}{x}$ and
$g(x)=\sqrt{5x+5}$

we could also have
$f(x)=\frac{9}{\sqrt{x}}$ and
$g(x)=5x+5$

or
$f(x)=\frac{9}{\sqrt{x+5}}$ and
$g(x)=5x$

there are many posibilities

A person riding a circular Ferris wheel sits 65 feet from the center. If they travel a distance of 92 feet during an initial rot

Temka [501]

We know that
the radius is 65 ft
circumference of a circle=2*pi*r
for r=65 ft
circumference of a circle=2*pi*65-----> 130*pi ft

if 2*pi (full circle) has a length of----------------> 130*pi ft
x------------------------------------------> 92 ft
x=92*2*pi/(130*pi)----------> x=1.4154 radians-------> x=1.42 radians

the answer is
1.42 radians

Compute i^1+i^2+i^3....i^99+i^100

fgiga [73]

Good morning ☕️

Answer:

Step-by-step explanation:

Consider the sum S = i¹ + i² + i³ +. . .+ i⁹⁹ + i¹⁰⁰

S = i¹ + i² + i³ + . . . + i⁹⁹ + i¹⁰⁰

S = a₁ + a₂ + a₃ +. . . + a₉₉ + a₁₀₀

then, S is the sum of 100 consecutive terms of a geometric sequence (an)

where the first term a1 = i¹ = i and the common ratio = i

FORMULA:______________________

$S=(term1)*\frac{1-(common.ratio)^{number.of.terms}}{1-(common.ratio)}$

_______________________________

then

$S=i*\frac{1-i^{100} }{1-i}$

or i¹⁰⁰ = (i⁴)²⁵ = 1²⁵ = 1 (we know that i⁴ = 1)

Hence

S = 0
