Answer:
The answer is 132
Step-by-step explanation:
Answer:
We know that Amber decided to mail copies of her photo to the 45 residents of her grandmother's assisted living facility, and after this, the function representing the photo shares is:
f(x) = 3*(4)^x + 45
We do not know the initial function, but with the given information we can assume that the original equation is:
g(x) = 3*(4)^x
Then the new function is:
f(x) = g(x) + 45.
This is a vertical translation, remember that for a function h(x), a vertical translation of N units is written as:
k(x) = h(x) + N
if N is positive, we have a translation of N units up
if N is negative, we have a translation of N units down.
in this case we have;
f(x) = g(x) + 45
This means that f(x) is a vertical translation of 45 units of g(x), then:
the graph of the new function is 45 units above the original function.
60% of the total (30) can swim
60% of 30 = (60/100)*30 = 0.60*30 = 18
So 18 children can swim
This means 30-18 = 12 cannot swim
---------------------------------------------------------
An alternative is to do it this way:
We know 60% can swim so that means 40% cannot swim.
Notice how 100% - 60% = 40%
Or in other words, the 60% and 40% add to 100%. This is because we have two choices: either the person can swim or cannot swim
Since 40% cannot swim, this means
40% of 30 = (40/100)*30 = 0.40*30 = 12
and we get the same result as before

Answer:
the answer for this is:
subtract 7 from 4 to get -3
you then have 2^-3
remove the negative exponent by rewriting as 1/(2^3)
