Answer:
7595.96 × 0.02 × x = y
Step-by-step explanation:
1. We start with $7595.96.
2. The interest is 2% or 0.02
3. Using this formula - P(Principle) x R(Rate) x T(Time) we pluck in the numbers.
4. 7595.96(Principle) x 0.02(Rate) x x(Time) = y(amount of money in the account after x years).
Answer:
7.6
Step-by-step explanation:
a^2 + b^2 = c^2
6.5^2 + x^2 = 10^2
42.25 + x^2 = 100
isolate x by subtracting 42.25 on both sides
x^2 = 57.75
square root of 57.75 or 7.6
Answer:
exponential decay
Step-by-step explanation:
The function is in the form
y = ab^x where a is the initial value and b is the growth or decay rate
If b >1 then it is growth
b < 1 then it is decay
f(x) = 5(2/3)^x
a = 5
b = 2/3
2/3 <1 so it is decay
Expand the binomial:
(√2/5 + 5/2 <em>i</em> )² = (√2/5)² + 2<em>i</em> (√2/5) (5/2) + (5/2 <em>i</em> )²
… = 2/25 + √2 <em>i</em> + 25/4 <em>i</em> ²
… = -617/100 + √2 <em>i</em>
1 nickel = 5 cents
1 dime = 10 cents
The total = $2.40
There’s a total of 30 coins.
12 nickels = $0.60
18 dimes = $1.80
Isabelle has 12 nickels.
