Answer: The first and last options are correct
Explanation:
The recursive formula is written in terms of the previous term of the sequence. From the information given,
the Arnold's are going to save a nickel on the first day of the month and double the amount each day of the month. Thus, the recursive formula would be
where
an - 1 defines a previous term
To write the explicit formula, we would apply the formula for finding the nth term of an arithmetic sequence which is expressed as
An = ar^(n - 1)
where
a is the first term of the sequence
n is the number of terms
r is the common ratio between consecutive terms
Thus,
r = 2 because the amount is doubling each day
n = number of days
a = value of 1 nickel = $0.05
By substituting these values into the formula,
the explicit formula is
A(n) = 0.05(2)^n - 1
Given function : 
.
We need to find the values of f(-2).
In order to find the value of f(-2), we need to plug x=-2 in the given fucntion .
Replacing x by -2, we get
We get (-2)^2 = -2 *-2*-2=-8 and (-2)^2 = -2 * -2 = 4.
.
f(-2) = -160 +12.
f(-2) = -148.
Therefore, correct option would be option D. That is f(-2)=-148.
Answer: Jose earns $169.89
Step-by-step explanation:I’m still trying to learn the step by step
The left-handed students12% are left handed, percent means per hundred. Change percent into per 100.
12% =
Then simplify the fraction by dividing the numerator and denominator by 4
=
=
This is the fraction showing the proportion of the left-handed students
The right-handed studentsDetermine the fraction showing the proportion of the right-handed students
1 - the left-handed
= 1 -
Equalize the denominator to 25
Simplify
This is the proportion of the right-handed students
<span>
Are there more right-handed or left-handed students?There are more right-handed students than the left-handed students, because 21/25 is more than 3/25</span>
X= 11
If you plug in 1 for X in the equation, you will get:
f(x) =3+8
3+8=11
Hope this helps.
