Answer:
5%
Step-by-step explanation:
The question showing a growing function that commonly used in compound interest calculation. The formula for compound interest is:
A = P (1 +r) ^ t
A= amount of the balance after a period of t
P= principal, the initial money deposit
r= rate
t= time
The percent of balance increase should be represented by the rate(r). In this equation, the principal will be 130, (1+r) will be 1.05, and time will be x.
The value of rate (r) will be:
(1+r) = 1.05
r= 1.05-1= 0.05 = 5%
Your answer is basically c.7
because you count the columns in the squared. graph or do the thing in the other graph numbers and lines ,just make it like a usual graph and that 's it
piece of cake

Answer:
2 real solutions
Step-by-step explanation:
We can use the determinant, which says that for a quadratic of the form ax² + bx + c, we can determine what kind of solutions it has by looking at the determinant of the form:
b² - 4ac
If b² - 4ac > 0, then there are 2 real solutions. If b² - 4ac = 0, then there is 1 real solution. If b² - 4ac < 0, then there are 2 imaginary solutions.
Here, a = 6, b = -20, and c = 1. So, plug these into the determinant formula:
b² - 4ac
(-20)² - 4 * 6 * 1 = 400 - 24 = 376
Since 376 is clearly greater than 0, we know this quadratic has 2 real solutions.

Answer:
![\frac{x^3}{3}+2x^2 + K\\\\](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E3%7D%7B3%7D%2B2x%5E2%20%2B%20K%5C%5C%5C%5C)
Step-by-step explanation:
We can equate the expression x^2+4x to f(x) and specify the variable of integration , the integrand and the symbol simply like this ,
Let,
![f(x)=x^2+4x\\\\F'(x)=f(x)\\\\\int f(x)\ dx=F(x) + K](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2%2B4x%5C%5C%5C%5CF%27%28x%29%3Df%28x%29%5C%5C%5C%5C%5Cint%20f%28x%29%5C%20dx%3DF%28x%29%20%2B%20K)
Where the integrand is f(x) , x is the variable of integration , c is the constant of integration , and ∫ is the symbol of integration.
The derivate of what function is x^2 + 4x?
To find that out we integrate the function because Integrating a differentiate is the process of obtaining the original process because Integrals are also called as Anti-derivatives.
So,
![\int\ x^2+4x \ dx](https://tex.z-dn.net/?f=%5Cint%5C%20x%5E2%2B4x%20%5C%20dx)
This is an indefinite integral which would result in an addition of a constant later on because it does not have limits. The variable of integration is x because there is only one variable present in this expression so naturally the variable of concern is x
so now we solve,
![\int\ x^2+4x \ dx\\\\\frac{x^3}{3}+4(\frac{x^2}{2}) + K\\\\\frac{x^3}{3}+2x^2 + K\\](https://tex.z-dn.net/?f=%5Cint%5C%20x%5E2%2B4x%20%5C%20dx%5C%5C%5C%5C%5Cfrac%7Bx%5E3%7D%7B3%7D%2B4%28%5Cfrac%7Bx%5E2%7D%7B2%7D%29%20%2B%20K%5C%5C%5C%5C%5Cfrac%7Bx%5E3%7D%7B3%7D%2B2x%5E2%20%2B%20K%5C%5C)
Where K is the constant of the indefinite integral.
