Answer:
Step-by-step explanation:
Given the function
f(x) = 2x³ -3x²+ 7
putting x=-1 to find f(-1)
f(-1) = 2(-1)³ -3(-1)²+ 7
= -2 + 3 + 7
= 8
putting x=1 to find f(1)
f(1) = 2(1)³ -3(1)²+ 7
= 2 - 3 + 7
= 6
putting x=2 to find f(2)
f(2) = 2(2)³ -3(2)²+ 7
= 16 - 12 + 7
= 11
Therefore,
84 and to check 84 x 52 = 4368
Answer:
<h2>1.08*(0.82y)</h2>
Step-by-step explanation:
Let us see...
y is the price.
y
Then, 18% off. This is:
y - (y*0.18) = 0.82*y
Then, we add 8%, so now it's 1.08% of this expression:
<h3>1.08*(0.82y)</h3>
Answer:
Third option - 8^(x/3)
Step-by-step explanation:
Substitute x with a value (e.g. 2) for all the options to find the answer.
The given geometric series as shown in the question is seen to; Be converging with its' sum as 81
<h3>How to identify a converging or diverging series?</h3>
We are given the geometric series;
27 + 18 + 12 + 8 + ...
Now, we see that;
First term; a₀ = 27
Second Term; a₁ = 2(27/3)
Third term; a₂ = 2²(27/3²)
Fourth term; a₃ = 2³(27/3³)
Thus, the formula is;
2ⁿ(27/3ⁿ)
Applying limits at infinity gives;
2^(∞) * (27/3^(∞)) = 0
Since the terms of the series tend to zero, we can affirm that the series converges.
The sum of an infinite converging series is:
S_n = a/(1 - r)
S_n = 27/(1 - (2/3)
S_n = 81
