Using compound interest, it is found that he must invest his money at a rate of 8.78% a year.
<h3>What is compound interest?</h3>
The amount of money earned, in compound interest, after t years, is given by:
In which:
- A(t) is the amount of money after t years.
- P is the principal(the initial sum of money).
- r is the interest rate(as a decimal value).
- n is the number of times that interest is compounded per year.
In this problem, the parameters are as follows:
t = 3, A(t) = 60000, P = 46150.3, n = 12.
Hence:
![\sqrt[36]{\left(1 + \frac{r}{12}\right)^{36}} = \sqrt[36]{1.3}](https://tex.z-dn.net/?f=%5Csqrt%5B36%5D%7B%5Cleft%281%20%2B%20%5Cfrac%7Br%7D%7B12%7D%5Cright%29%5E%7B36%7D%7D%20%3D%20%5Csqrt%5B36%5D%7B1.3%7D)
r = 12 x 0.00731451758
r = 0.0878.
He must invest his money at a rate of 8.78% a year.

Answer:
Ionic bonds usually occur between metal and nonmetal ions. For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals.
An ionic bond is held together by the electrostatic attraction between ions that are near one another. Electrostatic attraction is the attraction between atoms that have opposite charge and holds the atoms together in ionic bonds.
To answer this item, we are to multiply the given amount of wood that Jake can carry which is given to be 6 1/4 by the number of times his father can which is equal to 1 5/7. x = (6 1/4)(1 5/7)
x = 75/7
Thus, Jake's father can carry 10 5/7 pounds of wood. (I've had this question before btw)
Answer:
(1, 0)
Step-by-step explanation:
x = -b / 2a
x = 2 / 2(1)
x = 2 / 2
x = 1
y = x^2 - 2x + 1
y = (1)^2 - 2(1) + 1
y = 1 - 2 + 1
y = -1 + 1
y = 0
vértice: (1, 0)
