Recall the equation for a circle with center ( h , k ) and radius r . at what point in the first quadrant does the line with equation y = x + 1 intersect the circle with radius 6 and center (0, 1)?

answer:

450

step-by-step explanation:

you basically do 1350 * 1/3 or 1350/3

answer:

x > 10

step-by-step explanation:

47-4x< 7

subtract 47 from each side

47-47-4x< 7-47

-4x < -40

divide by -4.   when dividing by a negative, flip the inequality.

-4x/-4 > -40/-4

x > 10

answer:

see below.

step-by-step explanation:

the standard deviation   =   √   (∑(x - 10)^2 / 8 )   must be approximately = 1 if we take the mean to be 10.

this requires ∑ (x - 10)^2 to be approximately equal to 8.

the following   data set would fit the bill:

8.6   9   9   10 10   11   11   11.5.

the values of (x - 10)^2   could be 1.96, 1, 1, 0,0, 1, 1, 2.25 = 8.21

this would give a mean of about 10 and standard deviation of about 1.

answer:

the parent function of all quadratic functions is y = x^2
