True for x is equal to 1 and 0 (Sometimes True)

( {x}^{a} )( {x}^{b} ) =  {x}^{ab}

True for x greater than or equal to 0 (Sometimes True)

{ \sqrt{x} }^{2}   = x

Always True

{ \sqrt{x} }^{ 3 }  =  \sqrt{ {x}^{3} }

True for x does not equal 0 (Sometimes True)

\frac{ {x}^{a} }{ {x}^{b} }  =  {x}^{a - b}  \\

Never True

{x}^{0}  = 0

True for x is equal to 0 (Sometimes True)

{x}^{2}  +  {x}^{2}  =  {x}^{4}

Find in degrees the numeric value of the acute angle of rotation that eliminates the product term from the equation 7x2+24xy−34x
lutik1710 [3]

Rotating the graph of Ax^2+Bxy+Cy^2+Dx+Ey+F=0 with B\ne0 counterclockwise by \theta eliminates the xy term, where \cot2\theta=\frac{A-C}{B}. Plugging in, we have \cot2\theta=\frac{7}{24}, since C=0. Solving, we have \theta=\frac{1}{2}\cot^{-1}(\frac{7}{24})\approx\boxed{36.9^\circ}.

8x=21+5x

3x=21

2. You plant 48 seeds of a certain flower and 32 of them sprout. Find the
Neko [114]

Answer:

<em>The probability that the next flower seed will sprout is 0.667 or 66.7%</em>

Step-by-step explanation:

<u>Probability</u>

The experimental or empirical probability can be defined as the ratio of the number of times an event occurs to the total number of times the random activity was performed.

It can be calculated as the relative frequency of an event A in a sample space. The question states 32 seeds of a certain flower sprout out of 48 planted seeds. The relative frequency of success is computed as

\displaystyle P(A)=\frac{32}{48}=\frac{2}{3}=0.667

Thus, the probability that the next flower seed will sprout is 0.667 or 66.7%
