£440 is divided between David, Mark & Henry so that David gets twice as much as Mark, and Mark gets three times as much as H

Lesechka [4]

Mark received £ 132

<em><u>Solution:</u></em>

Given that £440 is divided between David, Mark & Henry

Let "d" be the share of david

Let "m" be the share of mark

Let "h" be the share of henry

Total amount is 440

Therefore,

share of david + share of mark + share of henry = 440

d + m + h = 440 ------- eqn 1

<em><u>David gets twice as much as Mark</u></em>

d = 2m ----- eqn 2

<em><u>Mark gets three times as much as Henry</u></em>

m = 3h

$h = \frac{m}{3}$ ------ eqn 3

<em><u>Substitute eqn 2 and eqn 3 in eqn 1</u></em>

$2m + m + \frac{m}{3} = 440\\\\\frac{6m + 3m + m}{3} = 440\\\\10m = 1320\\\\m = 132$

Thus Mark received £ 132

Please answer asap! show work!<br> 11. What is (f.g)(x)?<br> f(x) = x3 +3<br> g(x) = 2x2 + x - 1

Ksenya-84 [330]

Answer:

<u>2x⁵ + x⁴ - x³ + 6x² + 3x - 3</u>

Step-by-step explanation:

Given :

f(x) = x³ + 3
g(x) = 2x² + x - 1

Finding (f × g)(x) :

f(x) × g(x)
(x³ + 3)(2x² + x - 1)
2x⁵ + 6x² + x⁴ + 3x - x³ - 3
<u>2x⁵ + x⁴ - x³ + 6x² + 3x - 3</u>

A child drops a ball from a window that is 24 feet high. The ball strikes the ground in 3.0 seconds. What is the velocity of the

choli [55]

Answer:

The velocity of the ball the instant before it strikes the ground is 30m/s

Given the data in the question

Since the ball was initial at rest before it was dropped by the child

Initial velocity;

Time taken for the ball to hit the ground;

Final Velocity;

To find the velocity of the ball the instant before it hits the ground

We use the First Equation of Motion:

Where v is the final velocity, u is the initial velocity, t is time and a is the acceleration.

Now, since the ball was thrown from a particular height (window), it is under gravity and acceleration due to gravity;

Hence, the equation becomes;

We substitute our values into the equation

Therefore, the velocity of the ball the instant before it strikes the ground is 30m/s.
