Answer:
it's true! it's easier to solve for y because there's no coefficient in front of it unlike the second one that has "9y."
Answer:
yes, ±2
Step-by-step explanation:
The x-intercepts are found by setting y=0 and solving for x:
x^2/4 = 1
x^2 = 4
x = ±√4
x = ±2
The x-values of interest are -2 and +2.
I believe your answer should be 105x squared-1475x+70
sorry i'm not really sure how to put the little two above the first x but my answer is mathematically correct.
Answer:
After 9 years the account will be worth 13709.60$
Step-by-step explanation:
We are given the following in the question:
We are given the following in the question:
P = $8000
r = 6% = 0.046
n = 12
The compound interest is given by:
where A is the amount, p is the principal, r is the interest rate, t is the time in years.
Putting the values, we get,
![13709.60 = 8000\bigg(1+\dfrac{0.06}{12}\bigg)^{12t}\\\\\dfrac{13709.60}{8000} = \bigg(1+\dfrac{0.06}{12}\bigg)^{12t}\\\\\Rightarrow 1.7137 = (1.005)^{12t}\\\Rightarrow t \approx 9](https://tex.z-dn.net/?f=13709.60%20%3D%208000%5Cbigg%281%2B%5Cdfrac%7B0.06%7D%7B12%7D%5Cbigg%29%5E%7B12t%7D%5C%5C%5C%5C%5Cdfrac%7B13709.60%7D%7B8000%7D%20%3D%20%5Cbigg%281%2B%5Cdfrac%7B0.06%7D%7B12%7D%5Cbigg%29%5E%7B12t%7D%5C%5C%5C%5C%5CRightarrow%201.7137%20%3D%20%281.005%29%5E%7B12t%7D%5C%5C%5CRightarrow%20t%20%5Capprox%209)
Thus, after 9 years the account will be worth 13709.60$
