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 radical expression is an irrational number? A. √ 121 B. √ 65 C. √ 36 D. √ 64
alina1380 [7]

We will verify each options

option-A:

\sqrt{121}

we can factor it

\sqrt{121}=\sqrt{11*11}

\sqrt{121}=\sqrt{11^2}

\sqrt{121}=11

so, this is not irrational.........Answer

option-B:

\sqrt{65}

Since, it can not be factored

so, this is irrational.........................Answer

option-C:

\sqrt{36}

we can factor it

\sqrt{36}=\sqrt{6*6}

\sqrt{36}=\sqrt{6^2}

\sqrt{36}=6

so, this is not irrational.........Answer

option-D:

\sqrt{64}

we can factor it

\sqrt{64}=\sqrt{8*8}

\sqrt{64}=\sqrt{8^2}

\sqrt{64}=8

so, this is not irrational.........Answer

levacccp [35]
The answer is 9 centimeters rounded up. You multiply 11 squares by 8 squares which is 88(9 rounded up) and the answer is the same on each side which means the width is 9 centimeters rounded up.
