Answer:
f(x) = 4.35 +3.95·sin(πx/12)
Step-by-step explanation:
For problems of this sort, a sine function is used that is of the form ...
f(x) = A + Bsin(2πx/P)
where A is the average or middle value of the oscillation, B is the one-sided amplitude, P is the period in the same units as x.
It is rare that a tide function has a period (P) of 24 hours, but we'll use that value since the problem statement requires it. The value of A is the middle value of the oscillation, 4.35 ft in this problem. The value of B is the amplitude, given as 8.3 ft -4.35 ft = 3.95 ft. Putting these values into the form gives ...
f(x) = 4.35 + 3.95·sin(2πx/24)
The argument of the sine function can be simplified to πx/12, as in the Answer, above.
It has a constant daily growth rate of 1.5
Foil is just like distributive meathod rememebering meathood
so foil is
First
Outer
Inner
Last
so if you had
(a+b)(c+d)
you would do
First
a times c
Outer
a times d
Inner
b times c
Last
b times d so
we have
(b-3)(b+9)
FIRST
b times b=b^2
Outer
b times 9=9b
Inner
-3 times b=-3b
Last=-3 times 9=-27
add
b^2+9b-3b-27
add like terms
b^2+6b-27
answer is A
Answer:
r=1
Step-by-step explanation:
<u>Ratio of Values
</u>
A ratio compares two values by diving them. If the ratio is greater than one, then the value in the numerator is greater than the value in the denominator. The opposite relation gives ratios lower than 1. A ratio of 1 means both values are the same
We have a set of tiles numbered 1 to 30:
1,2,3,4,5,6...,29,30
Note that each odd-numbered tile is followed by an even-numbered tile. It means we have 15 odd tiles and 15 even tiles. The ratio is
r=1
