Which of the following gives a product of x^3 - 3x ?
Vilka [71]

Answer:

Option a

Step-by-step explanation:

Lets verify

RHS

\\ \rm\longmapsto x(x^2-3)

  • Use distributive law
  • a(b-c)=ab-bc

\\ \rm\longmapsto x(x^2)-3x

\\ \rm\longmapsto x^3-3x

\\ \rm\longmapsto LHS

Hence verifed

Find the solutions for a triangle with a = 16, c =12, and B = 63º.
maks197457 [2]

Answer:

b. A = 71.6°; C = 45.40°; b =15.0

Step-by-step explanation:

The missing values can be found with the help of the Law of Cosine and properties of triangles:

Side b (Law of Cosine)

b = \sqrt{a^{2}+c^{2}-2\cdot a \cdot c \cdot \cos B}

b = \sqrt{16^{2}+12^{2}-2\cdot (16)\cdot (12) \cdot \cos 63^{\circ}}

b \approx 15.022

Angle A (Law of Cosine)

\cos A = -\frac{a^{2} - b^{2}-c^{2}}{2\cdot b \cdot c}

\cos A = - \frac{16^{2}-15.022^{2}-12^{2}}{2\cdot (15.022)\cdot (12)}

\cos A = 0.315

A= \cos^{-1} 0.315

A \approx 71.639^{\circ}

Angle C (Sum of internal angles in triangles)

C = 180^{\circ} - 63^{\circ} - 71.639^{\circ}

C = 45.361^{\circ}

Hence, the right answer is B.

If you substracted 3 frome the exponent in an exponential function , what will happen to the graph​
Mekhanik [1.2K]

Subtracting a value from the exponent shifts the graph to the right.

So if you subtract 3, the graph would shift 3 units to the right.
