Step-by-step explanation:
$75 30% 0.70(75) = x $52.50
$18 65% 0.35(18) = x $6.30
$60 30% 0.70x = 42 $42
$35 20% 0.80x = 28 $28
$150 25% 0.75(150) = x $112.50
Y = xe^x
dy/dx(e^x x)=>use the product rule, d/dx(u v) = v*(du)/(dx)+u*(dv)/(dx), where u = e^x and v = x:
= e^x (d/dx(x))+x (d/dx(e^x))
y' = e^x x+ e^x
y'(0) = 1 => slope of the tangent
slope of the normal = -1
y - 0 = -1(x - 0)
y = -x => normal at origin
This question was already asked so I will put the answer here.
The correct answer is letter (B) {1,2,3,4,...,163}.The burj khalifa the tallest building in the world with 163 floors, is having problems with is air conditioning system. It is suspected that thedifference is air pressure between the first floor and the top floor is the problem. normal pressure for the bottom floor is 14.7psi. a building engineer uses the function p to analyse pressure p(f) represents the pressure on each floor, where f is the floor number.
Answer:-12×4+63=15
Step-by-step explanation:
Negative 12 time positive 4 equals to -48 plus 63 equals to 15
Answer:
B
Step-by-step explanation:
They all separately bought items therefore the number of items will be discrete. But they spent the same time all together,therefore total time will be continuous.
