Sue spend 56 minutes in reading.
<h3>What is Unitary Method?</h3>
Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Sue spent 1 hour 19 minutes less than Jared
Lucas spent 45 minutes less than Pete.
Pete spent 3 hours reading.
Since, pete spent 3 hours. So, Jared spent
= 3 hours or (180 minutes) - 45 minutes
= 2 hours 15 minutes.
Now, Seu spent = 2 hrs 15 minutes - 1 hour 19 minutes
= 56 minutes

First we multiply the numbers ignoring the decimal and then place the decimal in the position
3.04 *7.091 = 2155664
Now the first number has two digits after the decimal and the second number has three digits after the decimal.
Therefore in the final result we have to move the decimal (2+3) =5 place from the left,
So the answer would be 21.55664
So, the correct answer is 21.55664
Jerry calculated the answer correctly , but made an error in the placement of the decimal point. The answer is not reasonable because 2.155664 and 21.55664 mean two completely different answer far apart from each other
(6^-2)^2 = 1/1296 = 0.0007716049382716 hope this is what you were looking for. the math is right tho for (6^-2)^2 most calculators can do this easy just do 6^-2 then after just do ^2
The value of f(2) is -2 ⇒ 1st answer
Step-by-step explanation:
The form of the quadratic function is;
f(x) = ax² + bx + c, where
- a is the coefficient of x²
- b is the coefficient of x
- c is the numerical term
- x is the domain of the function and f(x) is the range of the function
∵ f(x) = -5x² - x + 20
- f(2) means value f(x) at x = 2
∵ x = 2
- Substitute x in the function by 2 to find f(2)
∵ f(2) = -5(2)² - (2) + 20
∴ f(2) = -5(4) - 2 + 20
∴ f(2) = -20 - 2 + 20
∴ f(2) = -2
The value of f(2) is -2
