Answer:
the percentage change on the drone is 42.86%
Step-by-step explanation:
The computation of the percentage change is shown below:
Since the helicopter was sold for $179.99
But amazon would be selling it for $125.99
So, the percentage change would be
= (Sale value - sale value by amazon) ÷ ( sale value by amazon) × 100
= ($179.99 - $125.99) ÷ ($125.99) × 100
= 42.86%
Hence, the percentage change on the drone is 42.86%
Answer:
39
Step-by-step explanation:
Two triangles are similar so we can use the similarity ratio to calculate the value of x this way we can find the length of FH
(x+8)/32 = (4x-25)/52 cross multiply expressions
52x + 416 = 128x - 800 export like terms to the same side of equation
416 + 800 = 128x - 52x
1216 = 76x divide both sides by 76
16 = x then the length of FH
4*16 - 25 = 39
Answer:
Step-by-step explanation:
g(x) = 3f(-2x)
= 3*([-2x)² + (-2x) - 2)
= 3 (4x² - 2x - 2)
= 3 * (4x² - 4x +2x - 2) {Rewrite the middle term}
= 3 *[ 4x(x - 1) + 2(x - 1)]
= 3* [ (x -1) *(4x + 2)]
= 3(x - 1)(4x + 2)
x - 1 = 0 ; 4x + 2 = 0
x = 1 ; 4x = -2
x =
Roots: x = 1 , (-1/2)
