Given that (x, y) = (5, 10), find r.a.2√5b.5√2c.5√5d.5√10

1 answer:

5 0

I am considering the point you have given is point on a circumference of a circle and center of circle is (0,0) and we have to calculate radius

so radius = root((x-h)^2 + (y-k)^2)

where (h,k) is center of circle

so r = root((5-0)^2+(10-0)^2)

= √(100+25) = √125 = 5√5

so answer is option c

if the cost of a movie ticket now averages $11.50 , interpret the meaning of the expression 11.50(1.083)

LUCKY_DIMON [66]

I believe the correct expression is: 11.50(1.083)^t where t is the time.

Now, we are given that the average price of the ticket is $11.5
The given expression means that this average value is dependent on the variable t. Therefore, the average price of the ticket increases exponentially with the time with the rate of growth equals 1.083

Now, to better understand this, we will get the price of the ticket at different times:
At t = 1: price = 11.50(1.083)^1 = $12.4545
At t = 2: price = 11.50(1.083)^2 = $13.4882235
At t = 3: price = 11.50(1.083)^3 = $14.60774605
We can notice that the price of the ticket increases exponentially as the time increases.

Hope this helps :)

Answer:

(13/10)H

got it on khan academy brainliest pls thx uwu

Remember that 30% in fraction form is 33/100

The amount of health points (H) restored would depend on the amount of the current H so it means it would add 30% of the current which we can write as:

(30/100)H

And since it would add that to the current total we can right the current total as:

(100/100)H

So our equation would be

=(30/100)H + (100/100)H

=(130/100)H

=(13/10)H
