Answer:

B I personally think..

Step-by-step explanation:

Hi,

Use Differential Formula :

d(u(x) • v(x))/dx = u'(x) • v(x) + u(x) • v'(x)

at x = 1 :

d(u(1) • v(1))/dx = u'(1) • v(1) + u(1) • v'(1)

d(u(1) • v(1))/dx = -5 • 6 + 4 • -2

d(u(1) • v(1))/dx = -30 - 8

d(u(1) • v(1))/dx = -38

Hope this helped :)

The latte is covered with a milk foam heart is covering 55 square cm of the coffee, then what is the area of the coffee NOT cove

Marysya12 [62]

Answer:

Step-by-step explanation:

The latte is what covered the coffee, Caffe latte is a coffee drink made with espresso and steamed milk, and this latte do form heart on the coffee, then we are told that the area of the latte heart is 55cm²

Then, space where latte is not form has a diameter 4cm

Then the radius is diameter divided by 2

r=d/2

r=4/2 =2

Then area of the circle which for the surface for the coffee is πr²

A=πr²

A=3.142×2²

A=12.568cm².

Area of coffee not covered is

55-12.568=42.432cm²

A refrigerator has a volume given by the trinomial y^3 + 5y^2 – 14y. What are the possible dimensions of the refrigerator? Use f

Sergeu [11.5K]

Y^3+5y^2-14y

y(y^2+5y-14)

y(y^2+7y-2y-14)

y(y(y+7)-2(y+7))

y(y-2)(y+7)

So there are infinite solutions with the only restriction being that y>2 as V>0
