Answer:

The American population was 20% of the British population.

Step-by-step explanation:

Let us call A the american population, B the British population before the migration, and x the population that migrated from America to Britannia.

Now, the population x that migrated was 20% of the american population:

(1).\: \: x = 0.2A,

and the same population x increase the British population by 4%:

x+B = 1.04B \\\\ (2). \:\:x = 0.04B.

Combining equation (1) and (2) we get:

0.2A = 0.04B

A = \dfrac{0.04B}{0.2}

\boxed{A = 0.2B}

Thus, the American population was 20% of the British population.

laiz [17]

Answer:

1 Batch... i think.

Step-by-step explanation:

So, like, half of 15 is 7.5. That makes two batches. I don't think we're supposed to say 0.5=1 batch here, cause that is unrealistic.

A rocket is fired upward from some initial distance above the ground. Its height (in feet), h, above the ground t seconds after
I am Lyosha [343]

Answer:

the object will attain maximum height at 3.5 seconds.

Step-by-step explanation:

The height of the object (in feet), h, above the ground t seconds after it is fired is given by h(t)=−16t2+112t+128.

128 represents 128 feet above the ground and this is the height from which the object was fired.

The given equation is a quadratic equation and plotting of this equation on a graph would give a parabola whose vertex would be equal to the maximum height travelled by the rocket.

The vertex of the parabola is calculated as follows,

Vertex = -b/2a

From the equation,

a = -16

b = 112

Vertex = - - 112/32= 3.5

So the object will attain maximum height at 3.5 seconds.
