Answer:
False
Step-by-step explanation:
The given formula is the "explicit" formula for the sequence.
The recursive formula would be ...
a[1] = 160
a[n] = 1/2·a[n-1] . . . . each term expressed in as a function of previous terms
The given statement is false.
Cost for a carnation is $0.75
Step-by-step explanation:
Let,
Rose = x
Carnation = y
According to given statement;
8x+5y=31.75 Eqn 1
x+3y=5.75 Eqn 2

Cost for a carnation is $0.75

Answer:
450 minutes
Step-by-step explanation:
Given
w = 45000 - 100t
Required
Determine how long it'll take to empty the pool
Being empty means there's no water in the pool.
So, we have to set w to 0 to get the value of t
i.e w = 0
Substitute 0 for w in w = 45000 - 100t
0 = 45000 - 100t
Collect Like Terms
100t = 45000
Divide through by 100.
t = 450
Hence, it'll take 450 minutes to empty the pool
Answer:
Point slope form:
The equation of line is given by:
.....[1]
where m is the slope and a line contains a point
.
As per the given statement:
Slope(m) = 3
. = (2, 1)
Substitute these in [1] we have;

therefore, the point slope form of a line with slope 3 that contains the point (2, 1) is;
