Answer: +15x
Explanation: Don't be thrown off if a variable like <em>x</em> is introduced in a multiplication problem that involves positives and negatives.
To simplify (+3) (+5x), it's important to understand that a positive times a positive is a positive. So (+3) (+5x) is +15x.
Answer:
(a) D(t)= -4.9 t^2 + vt
(b) 10 sec
(c) 122.5m
(d) At t= 4sec, v= 9.8m/s (upwards) and at t= 9sec, v= 39.2m/s (downwards)
(e) -24.5m
(f) -49m/s (i.e. downwards)
(g) 0
Step-by-step explanation:
(b) Time in the air = 2v/g = 10sec
(c) Maximum height =
=122.5m
(d) Velocity at any time t = v -9.8t
So, at t= 4sec, velocity = 49 – 9.8(4) =9.8m/s
at t= 9sec, velocity = 49 – 9.8(9) = -39.2m/s
(e) Average velocity =
= -24.5m
(g) the stone is thrown vertically upwards, so no horizontal distance covered.

Answer: 6</h3>
Explanation:
Using the rule that x = x^1, we can rewrite the p as p^1
So 11m^3n^2p is the same as 11m^3n^2p^1
The exponents are: 3, 2, 1
Those exponents add up to 3+2+1 = 6
The degree of a monomial like this is simply equal to the sum of the exponents.
