X =<br><br> a) 90<br> b) 135<br> c) 270

Serga [27]

If the outer arc is x, the inner arc is 360 - x

$90 = \frac{1}{2}( x - (360 - x) )$

$90 = \frac{1}{2}( x - 360 + x )$

$90 = \frac{1}{2}( 2x - 360)$

$180 = 2x - 360$

$2x = 360 + 180$

$2x = 540$

$x = 270$

A quantity with an initial value of 9100 grows continuously at a rate of 0.85% per hour. What is the value of the quantity after

ycow [4]

Answer:

$10,962,54$

Step-by-step explanation:

we know that

The equation of a exponential growth is equal to

$y=a(1+r)^x$

where

a is the initial value

r is the rate of growth

x is the time in hours

y is the value of the quantity

we have

$a=9,100\\r=0.85\%=0.85/100=0.0085$

substitute

$y=9,100(1+0.0085)^x$

$y=9,100(1..0085)^x$

For x=22 hours

substitute

$y=9,100(1..0085)^{22} =10,962,54$
