AB A, B, with, \overleftrightarrow, on top and C D ↔ CD C, D, with, \overleftrightarrow, on top intersect at point O OO as shown below. Select the most precise and correct statement about perpendicular lines from among those that are given. Choose 1 Choose 1 (Choice A) A A B ↔ AB A, B, with, \overleftrightarrow, on top is perpendicular to C D ↔ CD C, D, with, \overleftrightarrow, on top if the two lines never meet. (Choice B) B A B ↔ AB A, B, with, \overleftrightarrow, on top is perpendicular to C D ↔ CD C, D, with, \overleftrightarrow, on top if the two lines intersect such that the measure of ∠ A O D ∠AODangle, A, O, D equals the measure of ∠ B O C ∠BOCangle, B, O, C. (Choice C) C A B ↔ AB A, B, with, \overleftrightarrow, on top is perpendicular to C D ↔ CD C, D, with, \overleftrightarrow, on top if the two lines intersect such that ∠ A O D ∠AODangle, A, O, D is a right angle.

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
