9÷c
Quotient is division.
The quotient of 9 and c would be 9 divided by c
Circumference of a circle = pi x diameter
pi = 3.14
diameter = radius x 2
diameter = 10 x 2
diameter = 20
Circumference = 3.14 x 20
Circumference = 62.8 ft
Answer:
384 inches²
Step-by-step explanation:
The surface area of a cube is found by using 6a².
6 = the number of sides in a cube
a = the given dimension (in this case, 8 inches long)
SA = (6)8²
SA = 6(64)
SA = 384

Answer:
- f[1] = 3
- f[n] = 2·f[n-1] +4
- 108
Step-by-step explanation:
We observe that first differences of the given numbers are ...
10 -3 = 7
24 -10 = 14
52 -24 = 28
That is, each difference is 2× the previous one. This suggests an exponential relation that has a base of 2.
We notice that doubling a term doesn't give the next term, but gives a value that is 4 less than the next term. So, we can get the next term by doubling the previous one and adding 4.
Then our recursive relation is ...
f[1] = 3 . . . . the first term
f[n] = 2×f[n-1] +4 . . . . double the previous term and add 4
The next term is 2·52 +4 = 108.

Answer: B. 26</h3>
============================================
Use law of cosines to find angle A
a^2 = b^2 + c^2 - 2*b*c*cos(A)
9^2 = 6^2 + 14^2 - 2*6*14*cos(A)
81 = 36 + 196 - 168*cos(A)
81 = 232 - 168*cos(A)
81 - 232 = -168*cos(A)
-151 = -168*cos(A)
-168*cos(A) = -151
cos(A) = (-151)/(-168)
cos(A) = 0.8988095
A = arccos(0.8988095)
A = 25.9979801
A = 26 degrees approximately
