Answer:

(a) 240 balls.

(b) 720 balls.

Step-by-step explanation:

We have been given that Piper saw a large box of ping pong balls with 48 balls in each layer.

(a) To find the number of balls in 5 layers, we will multiply 5 by 48 as:

\text{Number of balls in 5 layers}=5\times 48

\text{Number of balls in 5 layers}=240

Therefore, the box with 5 layers will have 240 balls.

(b) To find the number of balls in 15 layers, we will multiply 15 by 48 as:

\text{Number of balls in 15 layers}=15\times 48

\text{Number of balls in 15 layers}=720

Therefore, the box with 15 layers will have 720 balls.

A particle moves on a straight line and has acceleration a(t)=24t+2. Its position at time t=0 is s(0)=3 and its velocity at time
user100 [1]

Answer:

It's position at time t = 5 is 593.

Step-by-step explanation:

The velocity v(t) is the integral of the acceleration a(t)

The position s(t) is the integral of the velocity v(t)

We have that:

The acceleration is:

a(t) = 24t + 2

Velocity:

v(t) = \int {a(t)} \, dt = \int {24t + 2} \, dt = 12t^{2} + 2t + K

K is the initial velocity, that is v(0). Since V(0) = 13, K = 13

Then

v(t) = 12t^{2} + 2t + 13

Position:

s(t) = \int {s(t)} \, dt = \int {12t^{2} + 2t + 13} \, dt = 4t^{3} + t^{2} + 13t + K

Since s(0) = 3

s(t) = 4t^{3} + t^{2} + 13t + 3

What is its position at time t=5?

This is s(5).

s(t) = 4t^{3} + t^{2} + 13t + 3

s(5) = 4*5^{3} + 5^{2} + 13*5 + 3

s(5) = 593

It's position at time t = 5 is 593.

vagabundo [1.1K]

Answer:

£24 : £32

Step-by-step explanation:

Add the parts of the ratio 3 + 4 = 7

Divide the amount by 7 to find the value of one part

£56 ÷ 7 = £8 ← one part of the ratio

3 parts = 3 × £8 = £24

4 parts = 4 × £8 = £32
