Whenever a quadratic equation is in the form
(i.e. the leading terms is 1), you can solve it by looking for two numbers that give when summed and when multiplied.
So, in your case,
So, we're looking for two numbers such that:
you can clearly check that these numbers are 3 and 4.
Answer:
Option A.
Step-by-step explanation:
If graph of a polynomial intersects the x-axis at x=c, where c is a constant, then (x-c) is a factor of that polynomial.
We need to find the factor of the polynomial function f(x) graphed on the coordinate plane.
From the given graph it is clear that graph of f(x) intersects the x-axis at x=3. It means (x-3) is a factor of f(x).
Therefore, the correct option is A.
Answer:
your answer is correct
Step-by-step explanation:
Answer: The future value of the investment after 2 years is $807.8
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
P represents the principal or amount invested.
R represents interest rate
T represents time in years
I = interest after t years
From the information given
T = 2 years
P = $700
R = 7.7%
Therefore
I = (700 × 7.7 × 2)/100
I = 10780/100
I = 107.8
The total amount in the account after 2 years would be
700 + 107.8 = $807.8
because the square root of 4 is 2 and the square root of 9 is 3 which means 2x3=6 and 9x4=36 and the square root of 36 is 6 because 6x6=36
