Answer:
i believe it would be 144
Step-by-step explanation:
<span>Fractions are numbers which can be represented in the form p/q, where p and q are WHOLE NUMBERS and q is not zero
Rational numbers are numbers which can be represented in the form p/q where p and q are INTEGERS and q is not zero
So your saying " all rational numbers are all numbers that can be represented as a fraction." is wrong.......
all fractions are rational numbers but NOT ALL rational numbers are fractions..</span>
Answer:3.1944
Step-by-step explanation:
(1÷1×3)+1÷(2×4)+1÷(3×5)+1÷(18×20)
The ball will be at height 19 feet first at 0.7 sec and then at 1.42 sec.
<u>Explanation:</u>
We need to find the time at which the ball will be at height 19 feet.
Equation:
h = 3 + 34t - 16t²
19 = 3 + 34t - 16t²
16 = -16t² + 34t
-16t² + 34t - 16 = 0
On solving the equation, we get
t1 = 0.7 s and t2 = 1.42s
Therefore, the ball will be at height 19 feet first at 0.7 sec and then at 1.42 sec.
