Answer:
The length RS = 7
Step-by-step explanation:
Here, we are interested in determining the length of RS
Let’s have the line segment arranged as follows;
Q R S
where QR = 9 and QS = 16
From the arrangement, we can deduce that;
QS = QR + RS
Thus;
RS = QS - QR
RS = 16 -9
RS = 7
Answer:
Step-by-step explanation:
We have to make 5 place serial number with first two as alphabets and last three as digits.
The alphabets are bonded to first 6 ( A, B, C, D, E, F) where as digits are 10 (say 1 to 10).
Let the serial number be S1 S2 S3 S4 S5.
For Alphabets
For S1 we have 6 alphabets.
Now for S2 we are left with 5 alphabets since there is no repetition one alphabet will be fix for S1.
So the possible combination for S1 S2= 6x5=30.
For Digits
We did the same as we did for alphabets, for S3 we have 10 possibilities, and for S4 and S5 9 and 8 respectively due to the no repetition condition.
So the possible combinations for S3 S4 S5 = 10x9x8=720
So the total number of serial numbers are 30+720=750.
Distribute it
42+49i+42i+49^2 (i^2=-1)
49i^2+91i+42
-49+91i+42
It equal to -7+91i

Answer: B) 36π cubic inches</h3>
=====================================
Work Shown:
V = volume of the sphere
V = (4/3)*π*r^3
V = (4/3)*π*(3)^3
V = (4/3)*π*27
V = (4/3)*27*π
V = ((4*27)/3)*π
V = (108/3)π
V = 36π
