A torch and a battery cost £2.50 altogether. The torch costs £2.00 more than the battery.

Answer:

1/5

Step-by-step explanation:

To find what fraction of the total price the battery is, we need to find out how much the battery alone is first.

Since the battery and torch together are £2.50 and the torch is £2.00, we can find the price of the battery by subtracting the total price to the price of the torch.

Battery Price = £2.50 - £2.00

Battery Price = £0.50

The fraction value of the torch is:

2.00 of 2.50 = 4/5

That then leaves us with:

0.50 of 2.50 = 1/5

To check we need to add the two fractions together.

1/5 + 4/5 = 5/5 or 1

Find the average rate of change for the function over the given interval.
jekas [21]

Answer:

The average rate of change for the function over the given integral

A(x) = \frac{e^{-2} -1}{2}

Step-by-step explanation:

Explanation

<u>Average rate of a functio</u>n:-

<u>We can define the average rate of change of a function from a to b</u>

<u></u>

A(x) = \frac{f(b)-f(a)}{b-a}

Given function f(x) = eˣ

Given interval      x = a = -2   and y = b = 0

f(a) = f(-2) = e⁻²

f(b) = f(0) = e⁰

A(x) = \frac{e^{-2} -1}{0-(-2)}

The average rate of change for the function over the given integral
