Answer:
Step-by-step explanation:
We need to find which statements are true.
Solution to find the same we will solve each statement and will conclude the same.
1. 
Now On solving we get;
So we can see that 0.70 > 0.66
Hence The given statement is False.
2.
Now On solving we get;
So we can see that 0.5625 > 0.5
Hence The given statement is True.
3. 
Now On solving we get;
So we can see that 1.33 > 1.2
Hence The given statement is False.
4. 
Now On solving we get;
So we can see that 0.82 > 0.66
Hence The given statement is False.
Answer:
Step-by-step explanation:
Many calculators use "E" to signify "×10^( )". Thus ...
... 1.3E-2 = 1.3×10^(-2)
This number in scientific notation is equivalent to the standard form number ...
... 1.3×0.01 = 0.013
X^3 + 8 =
<span>factorized
( x + 2 )</span><span>( <span><span>x2− 2x </span>+ 4 </span><span>)
</span></span>
<span>The definition of quadratic function is given by:
</span>
<span>
So the problem asks for two conditions:
<em>1. Write the quadratic function in factored form.
</em>
<em>2. The vertex has an x-coordinate of 3.</em>
Then the equation (1) must be written as follows:
</span>
<span>
To satisfy the two conditions:
So we are free to choose the value of one root, say:
Thus:
Finally,
the answer is:
The graph of this function is shown in the figure below.</span>
The half-life is 29 years.
116 : 29 = 4
So we will have 4 periods of half-life:
( 1/2 )^4 = 1/16
150 g * 1/16 = 9.375 g
Answer:
9.375 g of strontium -90 will remain after 116 years.
