A pharmacy uses 4×10−3 liter of an active ingredient in one dose of a medication. The active ingredient comes in a 2-liter bottl
Zina [12379]
Each bottle contains 2 liters of the active solution. To find out how many doses can be made, divide 2 L by 4x10^-3.
The number of doses is calculated as (2 L) / (4x10^-3 L/dose) = 500 doses.
Consequently, the pharmacy is capable of preparing 500 doses of the medication.

What is f(x) = 7x2 + 42x written in vertex form?
PIT_PIT [12445]

Answer:

\boxed{\boxed{y = 7(x+3)^2-63}}

Step-by-step explanation:

The standard vertex form for a parabola is given by,

y=a(x-h)+k

where,

(h, k) signifies the vertex of the parabola.

The function presented is,

\Rightarrow f(x) = 7x^2 + 42x

\Rightarrow y = 7x^2 + 42x

\Rightarrow y = 7(x^2 + 6x)

\Rightarrow y = 7(x^2 + 2\cdot x\cdot 3)

\Rightarrow y = 7(x^2 + 2\cdot x\cdot 3+3^3-3^2)

\Rightarrow y = 7(x^2 + 2\cdot x\cdot 3+3^3)-7\cdot 3^2

\Rightarrow y = 7(x+3)^2-7\cdot 9

\Rightarrow y = 7(x+3)^2-63

This represents the vertex form of the given function.

A rectangular prism has a volume of 170 cubic centimeters. The length of the prism is 5 centimeters, and the height of the prism
Inessa [12570]

Answer:

The prism's width is 2 cm

Step-by-step explanation:

The parameters provided are;

Volume of the prism = 170 cm³

Length of the prism = 5 cm

Height of the prism = 17 cm

The formula for the volume of the prism can be expressed as v = Length, l × Height, h × Width, w

Thus;

Volume = 5 cm × 17 cm × w = 170 cm³

Solving for width gives;

w = 170 cm³ / (5 cm × 17 cm) = 170 cm³ / (85 cm) = 2 cm

∴ Therefore, the prism's width = 2 cm.
