(5⁴)⁴ = 5⁴ x 5⁴ x 5⁴ x 5 ⁴ = 5⁽⁴⁺⁴⁺⁴⁺⁴⁾ = 5¹⁶
An other method: reminder : (xᵃ)ᵇ = xᵃᵇ; (5⁴)⁴ = 5⁴ˣ⁴ = 5¹⁶
Answer:
24 miles
Step-by-step explanation:
2/3 of 45 is 30. Divide 45 by 3, and you get 15. Divide 36 by 3, and you get 12. Subtract 15 from 45 and 12 from 30 and you get 24
hope this helped! :)
The slope of the line is -2 and 6x + 3y = 5 also has a slope of -2
Its 26.5 !! as (25×2+3)/2
Answer:
Part A:
The vertex : x = - b / 2 a = - 28 : ( - 2 ) = 14
y = f ( 14 ) = - 14² + 28 · 14 - 192 = 196 + 392 - 192 = 4
The vertex is ( 14, 4 ). It means that the maximum hourly profit is $4, and that the shop should sell 14 sodas to reach the maximum.
Part B :
We will solve the quadratic equation:
x 1/2 = ( - 28 +/- sqrt ( 784 - 768 ) ) / ( - 2 )
x 1 = 12, x 2 = 16.
It means that if the shop must sell more than 12 and less then 16 sodas if they want to make a profit ( 13, 14, or 15 ). If they sell 12, or 16 they will brake even.
I think
