If the simple interest on $6,000 for 3 years is $1,620, then what is the interest rate?
Volgvan

Answer:

Interest rate: 9%

Step-by-step explanation:

Using the simple interest formula: A=P(1+rt)

A=Final amount

P=Principal amount

r=rate

t=time (years)

We just need to put in the information we have from the question and solve for r.

7,620=6000(1+r3)

7,620/6000=1+r3

1.27=1+r3

0.27=r3

r=0.09

r=9%

What are the similarities and differences between the standard form and vertex form of a quadratic equation?
guajiro [1.7K]

Answer and Step-by-step explanation: <u>Standard</u> <u>form</u> of a quadratic equation is expressed as: y=ax²+bx+c, while <u>vertex</u> <u>form</u> is written as:

y=a(x-h)²+k.

The similarities between standard and vertex forms is that they show if the graph of the equation has a <u>minimum</u> (when a>0) or <u>maximum</u> (a<0) and it's easier to determine the y-intercept: for standard, the value of c is the intercept; for vertex, the value k is the intercept.

The advantage of standard form is that you can determine the product and sum of the equation's roots, which is a method to determine them.

The advantages of vertex form are: easier to find the vertex of the graph, which is the pair (h,k) and the axis of symmetry, which is the value of h.
