Step 2: She did not simplify under the square root correctly
under the square root:
(-6)^2 =36
and -4(5)(-8) =160
therefore under the square root it needs to be square root of 36+160 which is square root of 196.
That answer is 14 when square rooted
Answer:
The first three terms of the series are 8, 10 and 12. The number of terms is 12 to make the sum 228.
Step-by-step explanation:
The series is defined as
Put n=1.
Put n=2.
Put n=3.
The first three terms of the series are 8, 10 and 12.
It is an arithmetic series. The first terms is 8 and the common difference is
The sum of n terms of an arithmetic series is
Equate each factor equal to zero.
The number of terms can not be negative, therefore the value of n must be 12.
3:45 I believe. You add 25 to 3:05 which gives you 3:30, then you add the 15 which gives you your answer
Answer:
31 is the missing angle
Step-by-step explanation:
Right Angle = 90 degrees
90 - 59 = 31 degress
Move the decimal over 2 places to the left which will give you .419
