Mathematics

Sholpan [36]3 years ago

Consider the expression 3x-9x^3. It consists of two terms:

3x=3\cdot x

and

-9x^3=-3\cdot 3\cdot x\cdot x\cdot x.

The common factors in these terms are 3 and x. Then

GCF(3x,-9x^3)=3x.

Taking out the GCF, you obtain

3x-9x^3=3x(1-3x^2).

Answer: correct choice is B.

What is 8.57x10-⁴ in standered form ?
marusya05 [52]

Kaleerain5,

In order to get your answer you must remember that if the exponent is negative move to the left and if the exponent is positive you have to move to the right.

  • 8.57 \times 10^{-4}
  • The exponent is negative so move to the left:
  • 8. = .8 = .08 = .008 = .0008
  • = .000857

Therefore your answer is ".000857."

Hope this helps!

Evaluate: f(x) = f(g(3)), where<br>f(x)= 3x-2 and g(x)= x^2-4
dimulka [17.4K]

Hello from MrBillDoesMath!

Answer:  13

Discussion:

Evaluate f(g(3)).

g(3) = 3^2 -4 = 5 so

f(g(3)) = f(5) = 3*5-2 = 15 -2 = 13


Thank you,

MrB

An oblique cylinder has a diameter of 14 units. The volume of the cylinder is 1,176π cubic units.
Kaylis [27]

Answer:

24 units


Step-by-step explanation:

The volume of the cylinder = πr²x

Where r is the radius of the base and x is the height of the cylinder.

πr²x = 1,176π

π×(14/2)²x = 1,176π

dividing by π both sides,

(14/2)²x = 1,176

7²x = 1,176

49x = 1,176

x = 1,176/49

  = 24 units
