Answer:
$5,632.45
Step-by-step explanation:
Assuming it is compounded semiannually, A(t) = P(1 + (r/n))^(n*t)
A(4) = 5000*(1 + (0.03/2))^(2*4)
A(4) = 5,000*(1.015)^8
A(4) = 5,000*1.12649
A(4) = $5,632.45
Answer:
A. The height of the plant after week 3 was about 2.6 inches.
C. The height of the plant after week 9 was about 3.8 inches.
Step-by-step explanation:
The equation given:
Y = 0.2x + 2
x represents the number of weeks
substituting x = 3 into the equation , we will have
y = 0.2(3) + 2
y = 0.6 + 2
y = 2.6
This means that the height of the plant after week 3 was about 2.6 inches.
Also , substituting x = 9 into the equation will give
y = 0.2 (9) + 2
y = 1.8 + 2
y = 3.8
This means that the height of the plant after week 9 was about 3.8 inches.

Answer:
options 1,3,4 are functions.
Step-by-step explanation:
RULE: a relation is said to be a function if every element in the domain ( the numbers in the left side in the below sets) is related to only one number ( number on the right side in the below sets).
Let us check each option one by one:
1. 3 2
9 1
-4 7
0 -2
here each number on the left side is mapped to or is related to one number only.
so this relation is a function
2. 7 1
-5 2,3
1 0
here, "-5" is mapped to two different numbers. so this relation is not a function.
3. -2 -4
2 4
6 8
-6 -8
here each number on the left side is mapped to or is related to one number only.
so this relation is a function
4. 1 3
-1 3
2 3
-2 3
here each number on the left side is mapped to or is related to one number only.
so this relation is a function.
even if it is related to the same number, it doesn't matter.
it should follow the above given rule that's it.
