U need to first find the ratio to multiply 6 by, u can find the ratio by just putting 10/4 and simplify it which is 5/2 then just multiply that by 6:
6•5/2 = 30/2 = 15
X = 15
11.04 = 10(1.02)^n
1.104 = 1.02^n
ln 1.104 = ln 1.02^n
ln 1.104 = n ln 1.02
n = ln 1.104/ ln 1.02
n = 4.99630409516 (5 if rounded)
Ok so, y = mx + c is the equation of a line
When a graph is written in this form, m is the slope/gradient and c is the y - intercept.
This form is needed when a question asks for the equation.
Lets say they give 2 sets of coordinates, we can use the point slope formula to find the slope (m)
point slope formula:
(y₂ - y₁) = m(x₂ - x₁)
Then we substitute any of the two set of coordinates to find c, the y - intercept.
So the line has a gradient of m and y - intercept of c
Answer:
Equation of the parabola: y = 3 - 7x^2
Step-by-step explanation:
The equation of the parabola with vertex (h,k) is y = a(x - h)^2 + k
Thus, the equation of this parabola is y = ax^2+3
To find a, use the fact that the parabola passes through the point (1,−4):
-4 = a(1)^2 +3
Solving this equation, we get that a = −7.
Thus, the equation of the parabola is y = 3 − 7x^2.
