5 tens = 50
13 ones = 13
13 + 50 is 63.
So, 5 tens and 13 ones is equal to 63.
Answer:
yes
Step-by-step explanation:
e
The greater root is -4.
<u>Step-by-step explanation:</u>
- The given equation is
- This a quadratic equation which can be solved using the factorizing method.
- The general form of the quadratic equation is given by
where,
- a is the coefficient of x².
- b is the coefficient of x.
- c is the constant term.
In the given equation, a = 1, b = 10, c = 24.
- Sum of the roots ⇒ b
- Product of the roots ⇒ c
To find the roots of the equation :
- Sum of the roots ⇒ 6+4 = 10 (where b = 10).
- Product of the roots ⇒ 6×4 = 24 (where c = 24).
The solution is given by (x+6)(x+4) = 0.
The roots are given by (x+6) = 0 and (x+4) = 0.
Therefore, x= -6 and x = -4 are the roots of the equation
The greater root is -4.
Answer:
Exponential decay is the decrease in a quantity according to the law. (1) for a parameter and constant (known as the decay constant), where is the exponential function and is the initial value.
The object reaches the lowest height at 5 seconds
<h3>How to determine the time?</h3>
The function is given as:
f(t) = -2t² +22t + 6
Differentiate the function
f'(t) = -4t +22
Set to 0
-4t +22 = 0
Subtract 22 from both sides
-4t = -22
Divide both sides by -4
t = 5.5
Remove decimal points
t = 5
Hence, the object reaches the lowest height at 5 seconds
