The length of a football field should be measured in yards
Answer:
Jeff's Popcorn 130^3
Step-by-step explanation
(Jeff's 130^3) .
First 20.5*10^2 which is 20.5*100 which equals 2050.
Then find the volume for the other box of popcorn.
30*8^2 which is 1920.
subtract 2050 by 1920 and you get 130.
| u | = √(2² + (-1²)) = √5
| v | = √ ( 1² + (-8)² = √65
cos (u,v) = ( u * v ) / (| u | * | v |) =
(2 * 1 + ( -1 ) * ( - 8 )) / √5 √ 65 = (2 + 8) / √5 √65 = 10 / (√5 √ 65 )
The length of a larger diagonal:
d 1² = | u |² + 2 |u| |v| + | v |² = 5 + (2 √5 √65 * 10 / √5 √65 )+65
d 1² = 70 + 20 = 90
d 1 = √ 90 = 3√10
d 2² = 70 - 20 = 50
d 2 = √50 = 5√2
Answer:
The lengths of the diagonals are: 3√10 and 5√2 .
