Answer:
≈23.6 kg left.
Step-by-step explanation:
For determining this, we can simply use an exponential decay equation representing this scenario:
a: the initial amount
t: the amount of time
h: the half life
Now, substitute the numbers into the equation:
Now, solve this equation:
Use a calculator to solve for y:
y= 200(0.118)
y≈23.6 kg left.
2.50 is how each gallon cost because if you multiply 2.50 times the amount of gallons (9) it’s 22.50 in total
Answer:
131.41 degrees
Step-by-step explanation:
Given the equation
5(sinθ+3) = sinθ+12
5sinθ+15 = sinθ+12
5sinθ-sinθ = 12 - 15
4sinθ = -3
sinθ = -3/4
θ = arcsin(-0.75)
θ = -48.59 degrees
Since sin is negative in the 3rd quadrant
α = 180 + θ
α = 180 - 48.59
α = 131.41degrees
Hence the required angle is 131.41 degrees
Answer:
8x2y - 6x2 - 8xy2 - y2
Step-by-step explanation:
Equation at the end of step 1 :
(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+(8x•(y2)))-3y2)
Step 2 :
Equation at the end of step 2 :
(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+23xy2)-3y2)
Step 3 :
Equation at the end of step 3 :
(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-3y2)-(x2+8xy2-2y2)
Step 4 :
Equation at the end of step 4 :
(((((5•(x2))•y)-(5•(x2)))+3x2y)-3y2)-(x2+8xy2-2y2)
Step 5 :
Equation at the end of step 5 :
(((((5•(x2))•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)
Step 6 :
Equation at the end of step 6 :
((((5x2•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)
Step 7 :
Final result :
8x2y - 6x2 - 8xy2 - y2
