Simplify the expression: 3(5x)
Mademuasel [1]

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.

A stone is thrown straight up from earth with D(t)= -4.9 t^2 + vt where D = height in meters, t= time in seconds, and v= initial
Vedmedyk [2.9K]

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 = \frac{v^{2} }{2g} =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 = \frac{\int\limits^9_4 {v-9.8t} \, dt }{\int\limits^9_4 {1} \, dt } = -24.5m

(g) the stone is thrown vertically upwards, so no horizontal distance covered.

State the degree: 11m^3n^2p
Vadim26 [7]
<h3>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.
