Solve the equation y=2x^2-x-6 using the quadratic formula show the steps to solving

saul85 [17]

Answer:

$x1 = 2 \\ x2 = - \frac{3}{2}$

Step-by-step explanation:

$x = \frac{ - b + - \sqrt{ {b}^{2} - 4ac } }{2a} \\ x = \frac{1 + - \sqrt{ {( - 1)}^{2} - 4(2)( - 6) } }{2(2)} \\ x = \frac{1 + - \sqrt{1 + 48} }{4} \\ x = \frac{1 + - \sqrt{49} }{4} \\ x = \frac{1 + - 7}{4} \\ \\ x1 = \frac{1 + 7}{4} = \frac{8}{4} = 2 \\ x2 = \frac{1 - 7}{4} = - \frac{6 }{4} = - \frac{3}{2}$

Which Iink between two elements could you remove from the relation so that becomes a function?

OLEGan [10]

Answer:

Either (3,b) or (3,e) must be removed to form the above relation to be function.

Step-by-step explanation:

Given the relation between the elements of domain and range. we have to remove the link between two elements so that relation becomes a function.

A function is a relation in which each element in domain set maps into only one element of range set i.e one element can never have two images in range set.

Here, the element 3 in domain set maps into two element b and e in range set. Therefore, to form a function one link must be removed either

f(3)=b or f(3)=e

Hence, either (3,b) or (3,e) must be removed to form the above relation to be function.

The ages of members of a bowling league are normally distributed with a mean of 43 years and a standard deviation of 4 years.

Shkiper50 [21]

Answer:

35 is 2 standard deviations BELOW the mean of 43

51 is 2 standard deviations ABOVE the mean of 43

find z - score for + 2 S.D. then subtract the z-score for - 2 S.D.

This is the percentage ( in decimal form) of 200 members between the ages of 35 and 51 Can you finish?
