So all you have to do to find out how much she had before is add up both value 12.50+34.25= 46.75$ (answer)
because y-12.50=34.25 so you would have to had the 12.5 to the other side to find the value of Y
Answer:250 kilometers
Step-by-step explanation:
so it travels 100 kilometers north and another 150 kilometers north so 100+150 is 250 kilometers
Answer:
The most correct option for the recursive expression of the geometric sequence is;
4. t₁ = 7 and tₙ = 2·tₙ₋₁, for n > 2
Step-by-step explanation:
The general form for the nth term of a geometric sequence, aₙ is given as follows;
aₙ = a₁·r⁽ⁿ⁻¹⁾
Where;
a₁ = The first term
r = The common ratio
n = The number of terms
The given geometric sequence is 7, 14, 28, 56, 112
The common ratio, r = 14/7 = 25/14 = 56/58 = 112/56 = 2
r = 2
Let, 't₁', represent the first term of the geometric sequence
Therefore, the nth term of the geometric sequence is presented as follows;
tₙ = t₁·r⁽ⁿ⁻¹⁾ = t₁·2⁽ⁿ⁻¹⁾
tₙ = t₁·2⁽ⁿ⁻¹⁾ = 2·t₁2⁽ⁿ⁻²⁾ = 2·tₙ₋₁
∴ tₙ = 2·tₙ₋₁, for n ≥ 2
Therefore, we have;
t₁ = 7 and tₙ = 2·tₙ₋₁, for n ≥ 2.
Step-by-step explanation:
A = P (1 + r/n) (nt)
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per unit t
t = the time the money is invested or borrowed for
p = 3000
r = 5%/100 = .05 (has to be in decimal format)
n = 2
t = 1
A = 3000(1 + .05/2)⁽²ˣ¹⁾ note (make sure you use ^ (power of) for the 2x1)
use PEMDAS to work out problem

A = 3000(1 + .05/2)⁽²ˣ¹⁾
a = 3000(1 + .025)^²
a = 3000(1.025)^2
a = 3000 x 1.050625
a = 3151.875
she would have $3,151.88
