Answer:
<h3>31</h3>
Step-by-step explanation:
<h3>Let the other part be x.</h3>
<h3>Now,</h3><h3 /><h3>24:x=3:4</h3>
<h3>3x=96</h3><h3 /><h3>X = 96/3 = 32</h3>
<h3>1</h3>
<h3>Other part = 32</h3>

Answer:
The conjugate of 2i + 9 = -2i + 9
Product of (2i+9) and (2i+9) is 36i + 77
Step-by-step explanation:
Given - 2i + 9
To find - Find the conjugate and product of the following surds
Proof -
We know that,
The sum and difference of two simple quadratic surds are said to be conjugate surds to each other.
To find a complex conjugate, simply change the sign of the imaginary part (the part with the i ).
So,
The conjugate of 2i + 9 = -2i + 9
Now,
Product of surd (2i+9) is
(2i+9)(2i+9) = 2i(2i) + 2i(9) + 9(2i) + 9(9)
= 4i² + 18i + 18i + 81
= -4 + 36i + 81 { because i² = -1 }
= 77 + 36i
⇒Product of (2i+9) and (2i+9) is 36i + 77
Answer:
Studying probability and statistics will allow you to see the world from an entirely different perspective, since the subjects will give you the tools to model and analyze situations, which involve uncertainty.
