Answer:
20
Step-by-step explanation:
add all the numbers up
the two consecutive numbers are 56 and 57
x+x+1=113
2x+1=113
2x=113-1
2x=112
x=112/2
x=56
therefore, x=56
x+1= 56+1= 57
The dot product will have you multiply the corresponding coordinates and add up the products
v dot w = (6*(-7)) + (7*5) + (-3*2)
v dot w = -42 + 35 - 6
v dot w = -7 - 6
v dot w = -13
Answer: -13
Answer:
26.8 pi or approx. 84.19
Step-by-step explanation:
Circumference can be found by multiplying the diameter by pi. The diameter is twice the radius, which in this case is 13.4, so it's 13.4 * 2 = 26.8.
Multiply by pi, and you've got your answer!
