First we find x of p:

x = 2 \times ( - 3) - \frac{1}{2} \times 4 + \frac{2}{5} \times 5 \\ = - 6 - 2 + 2 = - 6

then we find y of p:

y = 2 \times 2 - \frac{1}{2} \times ( - 6) - \frac{2}{5} \times ( - 10) \\ = 4 + 3 + 4 = 11

so

p = \binom{ - 6}{11}

and

|p| = \sqrt{ {( - 6)}^{2} + {11}^{2} } \\ = \sqrt{36 + 121} = \sqrt{157} = 12.53

a school district requires all graduating seniors to take a mathematics test. This year, the rest scores were approximately norm
Klio2033 [76]
A score of 85 would be 1 standard deviation from the mean, 74.  Using the 68-95-99.7 rule, we know that 68% of normally distributed data falls within 1 standard deviation of the mean.  This means that 100%-68% = 32% of the data is either higher or lower.  32/2 = 16% of the data will be higher than 1 standard deviation from the mean and 16% of the data will be lower than 1 standard deviation from the mean.  This means that 16% of the graduating seniors should have a score above 85%.

The parabola y=x^2 is scaled vertically by a factor of 5/2. What is the equation of the new parabola?
Ray Of Light [21]
For this case we have the following transformation:
 Assume k> 0
 To graph f (x) + k, move the graph k units up.
 Applying the transformation we have:
 y = x ^ 2 + 5/2
 Answer:
 
The equation of the new parabola is:
 
y = x ^ 2 + 5/2
