Can the sum of two mixed numbers be equal to 2? Explain why or why not.

1 answer:

6 0

-- A "mixed number" is (a whole number) plus (a fraction).

-- Two mixed numbers = (two whole numbers) and (two fractions).

-- The smallest whole number is ' 1', so when you add up all of that,
the smallest possible sum is (2) plus (two fractions).

-- So the sum must always be greater than 2 .

============================================

THAT'S IF BOTH MIXED NUMBERS ARE POSITIVE .

If one of them is negative, then it's easy to do:

(3 and 1/2) + negative (1 and 1/2) = 2

(25 and 7/10) + negative (23 and 7/10) = 2

Answer: NO

Step-by-step explanation:

The functions that models the height of the ball is given as

h(t) = -5t2 + 40t + 100

Where

a = -5, b = 40, c = 100

The time the ball will reach the maximum height will be the vertex of the parabola. At the line of symmetry, the time t will be:

t = -b/2a

Substitute b and a into the formula above.

t = - 40 / -5 = 8

Substitute 8 for t in the function f(t)

h(t) = - 5(8)^2 + 40(8) + 100

h(t) = -5(64) + 40(8) + 100

Open the bracket

h(t) = -320 + 320 + 100

h(t) = 100

The maximum height of the ball is 100m

Given that the power lines is 185 metres above the ground. The golf ball will therefore not hit power lines because the maximum height the ball can go is 100 metres
