With negative numbers the larger the number the lower the value. For example -2 is less than -1
The order from least to greatest would be:
-12, -4.3, -1 1/2
Let y = √4+7t
then u= 4+7t
y=√u = u^½
du/dt= 7
dy/du = ½U^-½
dy/dt = du/dt • dy/du
= 7×½U^-½
= 7/2√U
= 7 / (2{√4+7t})

Answer:
6.0 x 10^2
Step-by-step explanation:
(7.3 X 10) + (2.4 X 10^7)
(4 X 10^4)
= 73 + 24000000
40000
= 24000073
40000
= 6.0 x 10^2
Answer:
x(1 - .4)
Step-by-step explanation:
x = regular price.
1 - .4 = .6 = 60%
The sale price is equal to the full price (aka x) minus the discounted price (40% of x = 40/100 times x = .4x)
Therefore sale price = x - .4x or x(1 - .4)
