Answer:
Interest Chaney earns after 3 years is $56.85
Step-by-step explanation:
Given:
Amount deposited = $1435.73
Simple annual interest rate = 1.32% = 1.32/ 100 = 0.0132
To find: Interest after 3 years
We know that the formula to calculate the interest amount is
Simple interest (S.I.) = 
where,
P is the initial amount deposited
r is the rate of simple interest in percentage
t is the time in years for which interest is to be calculated
Substituting the known values in the formula, we get
S.I = 
= 56.85
Hence the interest Chaney earns after 3 years is $56.85
Answer:
2730
Step-by-step explanation:
700*39/10
700*39 = 27300
Then you divide by 10
So 2730.
Answer: y² = 8x
Step-by-step explanation:
The set of points which are equidistant from one point and from a line is a parabola.
In this particular case we have directrix line × = -2 so that means focus must be on the x-axis and with coordenates f (2,0) and p = 2 (the distance between the vertex and the focus with that information we can get the equation
vertex ( 0, 0) p = 2 the parabola open to the left so is of the form
y² =- 4*p*× ⇒ y² = 8x
