Step-by-step explanation:
Given that:
a = 2ˣ
b = 2ˣ⁺¹ = 2ˣ * 2¹ = 2.2ˣ
Now,
{(8a³)/b²}
Substitute the value of x and y in expression then
= [{8(2ˣ)³}/(2.2ˣ)²]
= [(8*2³ˣ)/{2² * (2ˣ)²}]
= {(8*2³ˣ)/(4 * 2²ˣ)}
[since, (aᵐ)ⁿ = aᵐⁿ]
= {(2 * 2³ˣ)/2²ˣ}
= {(2 * 2²ˣ * 2ˣ)/2²ˣ}
[since (2a = a+a, that means 3x = 2x + x)]
= 2 * 2ˣ
= 2ˣ⁺¹
[since (aᵐ * aⁿ = aᵐ+ⁿ)]
<u>Answer:</u> Therefore, {(8a³)/b²} = 2ˣ⁺¹ .
Please let me know if you have any other.
Function: y = 4|x| - 1.
Domain: R (all real numbers).
Range: As we know, the absolute value of x is always a non-negative number:
|x| >= 0
4|x| >= 4 * 0
4|x| >= 0
4|x| - 1 >= -1
y >= -1 <----- this is the range
I hope this helps. =)
A= 0.25 or 1/4

<u>Answer-</u>
An angle is labeled with either one capital letter or three capital letters
<u>Solution-</u>
<em>Point-</em>
As a point is 0 dimensional, so you just need 1 point to define a point.
<em>Line- </em>
As a line is 1 dimensional,so you need 2 points to define a line.
<em>Plane-</em>
A plane is 2 0r 3 dimensional, so you need 3 points to define a plane.
<em>Angle-</em>
An angle measures the amount of turn. An angles is labeled with a single letter at the vertex, as long as it is perfectly clear that there is only one angle at this vertex. Otherwise, it is named according to the intersecting lines with 3 letters.
