19) Two of the dozen eggs in a carton are cracked. About what percent of the carton is not cracked? (Round to the nearest whole
777dan777 [17]

Answer:

83%%

Step-by-step explanation:

We have that 2/12=1/6 of the eggs are cracked, so 1-1/6=5/6 of the eggs are not cracked.

Recall that 1/6=0.1666666666.... This means that 5/6=1-1/6=1-0.166666666...=0.833333333....

Rounding this to the nearest whole percent gives 83%%.

Using the Completing the Square method, what are the zeros of the quadratic function f(x) = 2x2 + 8x - 3?
Ipatiy [6.2K]

Answer:

A.

Step-by-step explanation:

1) to rewrite the given equation:

f(x)=2(x²+4x)-3; ⇔ f(x)=2(x²+4x+4)-3-8; ⇔ f(x)=2(x²+4x+4)-11; ⇔ f(x)=2(x+2)²-11;

2) the roots are:

\left[\begin{array}{ccc}x=-\sqrt{\frac{11}{2}}-2 \\x=\sqrt{\frac{11}{2}}-2 \end{array}

3) finally, the correct answer is A.
