HELP for (ii)…..how do we find a?
Mariana [72]

By using the information given on the graph, we can see that a = 3.

<h3>How to find the value of a?</h3>

Here we have an exponential of the form:

y = p*a^x

And by looking at the graph, it passes through (0, 4) and (2, 36), so we can write:

4 = p*a^0\\\\36 = p*a^2

From the first equation we get that p = 4, replacing that on the second one we get:

36 = 4*a^2\\\\36/4 = 9 = a^2\\\\\sqrt{9} = 3 = a

So we conclude that a = 3.

Which of these triangle pairs can be mapped to each other using a single reflection?​
kondor19780726 [428]

Answer:

Second triangle pair

Step-by-step explanation:

In a reflection, the shape is flipped. In the first pair, the corresponding sides as shown by the lines, and the corresponding angle are already in the same position. In the second pair, Δ MLN can be reflected so that line LN match with EG and line LM matches with line EF. ∠L and ∠E will also be mapped to each other when one triangle is reflected.

This is called a double equation. If you solve for X, you would get 'any whole number.'
