The exponential function used to represent the profit after t years is
<h3>Exponential function</h3>
An exponential function is in the form:
y = abˣ
where y, x are variables, a is the initial value of y, and b is the multiplier.
Let y represent the profit after t years.
Since the profit on a given day is $550 and is growing exponentially at a rate of 60% per year. Hence:
- a = 550
- b = 100% + 50% = 1.6
The profit function is given by:

Use the distributive property to express the sum of the 2 whole numbers 15 and 30 with common factors as a multiple of two whole numbers with a sum of no common factor the solution would be (15 plus 30) = 15(1+2)
<em><u>The equation of the function is:</u></em>
<em><u>Solution:</u></em>
<em><u>The vertex form of equation is given as:</u></em>
Where, (h, k) is the vertex
Given that, The graph of a quadratic function has the vertex (4, 2)
(h, k) = (4, 2)
Substitute in eqn
And passes through the point (5,5)
Substitute (x, y) = (5, 5) in above
Substitute a = 3 and (h, k) = (4, 2) in vertex form
Thus the equation of function is found
Answer:
B
Step-by-step explanation:
Given
x² + 14x = 51
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(7)x + 49 = 51 + 49 , that is
(x + 7)² = 100 ( take the square root of both sides )
x + 7 = ± = ± 10 ( subtract 7 from both sides )
x = - 7 ± 10
Thus
x = - 7 - 10 = - 17
x = - 7 + 10 = 3
