Base and height so you would multiply 1/2 with 4 then divide by two and you get your answer
Evaluating the given sequence, it is evident that the next number is twice the number prior to it. Thus, the given is a geometric sequence with first term (a1) equal to 1 and common ratio of 2. The geometric series may be calculated by the equation,
Sn = a1 x (1 - r^n) / (1 - r)
where Sn is the sum of n terms in this case, n = 11.
Substituting the known values,
<span> Sn = 1 x (1 - 2^11) / (1 - 2) = 2047
</span>
Thus, S11 is 2047.
This is what is in the middle of the second paragraph. That statement is correct.
I don't know that it is any simpler or not, but what they have done in the answer is rationalize the denominator. That means that the denominator is no longer under the square root sign.
To get that result, you multiply numerator and denominator by √F
When you do that, your get
This results in the middle answer.
The answer for 32% of 50 is 16.
Answer: x=38
Step-by-step explanation:
x+(-15)=23
x-15=23
+15 +15
x=38
When there is a positive and negative sign the negative sign cancels the positive sign.
