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.
The mode is 85, because it is the most occurring in the data set.
hope that helps :)
The first thing you should do is verify that the ordered pairs satisfy equality. If so, then that pair ordered belongs to the line. Let us begin:
3x-4y = 9
(-1.3)
3 (-1) -4 (3) = 9
-3-12 = 9
-15 = 9 (Does not belong)
(2/3, -7 / 4)
3 (2/3) -4 (-7/4) = 9
6 + 28 = 9
34 = 9 (Does not belong)
(-5, -6)
3 (-5) -4 (-6) = 9
-15 + 24 = 9
9 = 9 (Yes, it belongs)
(1, -3 / 2)
3 (1) -4 (-3/2) = 9
3 + 6 = 9
9 = 9 (Yes, it belongs)
answer
ordered pairs are
(-5, -6)
(1, -3 / 2)
Answer:
Kayleigh will have a total of $4608.
Step-by-step explanation:
First, you use the formula, I=PRT (Interest=Principal, Rate, Time), then you distribute the numbers: (I=4500x0.8%x3) when you multiply them all, you get $108, then you lastly add 108 to 4500, and you get your final answer of $4608.
