V=u + at
V - u = at divide both sides by
t
(V-u)/t =a
a = (v - u) /t
Answer:
Step-by-step explanation:
9 - ratio 3:5
10 1/8 + 1/4 = 1/8 + 2/8 = 3/8 of the pizza eaten
so 5/8th of the pizza is left
In y = mx + b form, the slope is in the m position and the y intercept is in the b position.
y = (m)x + (b)
y = -5 x + 5.....slope (m position) = -5....y int (b position) = 5
Answer:
t ≈ -2.014 or 3.647
Step-by-step explanation:
Add the opposite of the expression on the right side of the equal sign to put the equation into standard form.
4.9t² -8t -36 = 0
You can divide by 4.9 to make this a little easier to solve.
t² -(8/4.9)t -36/4.9 = 0
Now, add and subtract the square of half the x-coefficient to "complete the square."
t² -(8/4.9)t +(4/4.9)² -36/4.9 -(4/4.9)² = 0
(t -4/4.9)² -192.4/4.9² = 0 . . . . simplify
Add the constant term, then take the square root.
(t -4/4.9)² = 192.4/4.9²
t -4/4.9 = ±(√192.4)/4.9
t = (4 ± √192.4)/4.9
t ≈ {-2.014, 3.647}
