Answer:
A
Step-by-step explanation:
Looking at the function, we have;
V(t) = 1,000(1.06)^t
Mathematically, the amount earned on an investment that offers a particular constant percentage return to a particular number of years can be written as;
V = I(1 + r)^t
where V is the value of the investment after some certain number of years
I is the initial amount invested
r is the constant percentage increase
and t is the number of years.
Let’s now re-write what we can deduce in the question.
This is;
V(t) = 1000(1 + 0.06)^t
Thus what this 0.06 represents is r which is the constant interest rate
Use pythagora's theorem to test if it is a right triangle
c^2 = a^2 + b^2
65^2 = 52^2 + 43^2
4225 = 2704 + 1849
4225 =/= 4553
therefore it is not a right triangle as it does not comply to pythagora's theorem

2+2=4
Step-by-step explanation:
Answer:
The expanded form of 168.023 is 100 + 60 + 8 + 
+ 
Step-by-step explanation:
Expanded form:
- Is a way to write numbers to see the math value of the digits.
- When numbers are separated into their place values and decimal places they can also form a mathematical expression.
- Ex: 5,325.27 in expanded form is 5,000 + 300 + 20 + 5 +
+ 
= 5,325.27
Let us solve the question
∵ The number is 168.023
∵ Its hundreds digit is 1
∴ Its value = 100
∵ Its tens digit is 6
∴ Its value = 60
∵ Its units digit is 8
∴ Its value = 8
∵ Its tenths digit is 0
∴ Its value = 0
∵ Its hundredths digit is 2
∴ Its value =
∵ Its thousandths digit is 3
∴ Its value =
∴ The expanded form of 168.023 = 100 + 60 + 8 + +
Price of DVD player ≥ $150
Saved = $80
Amount needed = $150 - $80 = $70
Saving per week = $10
Let x be the number of weeks needed:
80 + 10x ≥ 150
10x ≥ 150 - 80
10x ≥ 70
x ≥ 70 ÷ 10
x ≥ 7
Answer: She needs to save for for at least 7 weeks.
