It look like that.
Diameter = 2 so the radius = 1/2 * diameter = 1in

Volume of the cylinder = pi r^2 h

where h = height of the cylinder = 9 in

so volume = pi * 1^2 * 9 = 28.27 in^2 to nearest hundredth

1. Andrew ran a marathon in about 1.56 x 10^4 s. (a) Write Andrews time in standard notation. (b) Evelyn ran a marathon in 4 h a

romanna [79]

Answer:

(a) 15,600 s
(b) Evelyn

Step-by-step explanation:

(a) 1.56×10^4 = 1.56×10000 = 15,600

(b) There are 3600 seconds in an hour, so Andrew's time was

15600 s/(3600 s/h) = 13/3 h = 4 1/3 h

1/3 hour is 20 minutes, so Evelyn's time of 4:16 is shorter than Andrew's time of 4:20.

Let f(x)=x+3 and g(x)=1/x. The graph of (f*g)(x) is shown below.

Vlad [161]

For this case we have the following functions:
$f (x) = x + 3

g (x) = 1 / x$ When composing the functions we have:
$(fog) (x) = f (g (x))
$
Substituting values we have:
$(fog) (x) = ((1 / x) +3)
$
Rewriting:
$(fog) (x) = 1 / x + 3
$
The function has a horizontal asymptote at y = 3.
Therefore, the range of the function is all reals minus y = 3.

UGH GEEZ PLEASE HELP

Answer:

$0.40

Step-by-step explanation:

1st week total: 12.99 + 10.50 + 9.89 + 6.90 + 7.58 = $47.86

5 days total so the mean of 1st week: 47.86 / 5 = $9.57

2nd week, 2 more in total of 1st week = $47.86 + $ 2 = $49.86

The mean of 2nd week: 49.86 / 5 = $9.97

$9.97 - $9.57 = $0.40

2nd week increased 40 cents or $0.40
