F(x) = -1/2x is it increasing, decreasing or constant
kap26 [50]

Answer:

The function is decreasing.

Step-by-step explanation:

f(x) = x is the parent function, when you make x negative it decreases rather than increasing. the use of the slope (1/2) doesn't change whether it it increasing or decreasing. as long as the negative sign is in front, it will decrease.

A large rectangular shaped aquarium has a volume of 300 ft3. If the aquarium has a height of 3 feet and a length of four more fe
KIM [24]

Answer:

length is 14.4ft and the width is 12.4ft

Step-by-step explanation:

Volume of the aquarium = length * width * height

Given

Volume = 300ft^3

Height = 3feet

l = w+4

Substitute

300 = 3w(w+4)

100 = w(w+4)

100 = w^2+4w

w^2+4w-100 = 0

w = 4±√16+400/2

w =4±√416/2

w = 4±20.4/2

w = 24.4/2

w = 12.2feet

Since l = w+4

l = 12.2+4

l = 16.4ft

hence the length is 14.4ft and the width is 12.4ft

The bases of a circular cylinder are two ___ circles.
Blababa [14]
Well,

A cylinder is actually a special type of prism.  A prism is a 3-D figure made by taking a simple closed plane curve and translating it across space in a certain direction and for a given distance and then connecting the preimage and the image.  A cylinder is just a prism made with a circle.

We know from translations that the image is congruent to the preimage.  Thus, the bases of a (circular) cylinder are two congruent circles.
