A circle has a secant AC and a tangent AD that intersect outside of the circle. If the
measure of ZA is 29° and the measure of BD is 43°, then determine the measure of
CD.

A Circle Has A Secant AC And A Tangent AD That Intersect Outside Of The Circle. If Themeasure Of ZA Is

Answers

Answer 1

Answer:

CD = 101°

Step-by-step explanation:

The secant- tangent angle DAB is hlf the difference of the intercepted arcs, that is

[tex]\frac{1}{2}[/tex] (CD - BD ) = 29° ( multiply both sides by 2 )

CD - BD = 58°, that is

CD - 43° = 58° ( add 43° to both sides )

CD = 101°

A line passes through the given points. Write an equation for the line in point-slope form. Then rewrite the equation in slope-intercept form. (1 , 1/2), (3, 2)
A) y + 1/2 = 3/4 ( x + 1 ) ; y = 3/4x + 1/4
B) y − 1/2 = 3 ( x − 1 ) ; y = 3x − 1/4
C) y − 1/2 = 3/4 ( x − 1 ) ; y = 3/4x − 1/4

Answers

Answer:  C

Step-by-step explanation:

Find Slope first

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

[tex]m=\frac{2-.5}{3-1}[/tex]

[tex]m=1.5/2\\m=3/4[/tex]

Slope is 3/4

Chose a point to put in point slope form

(1,1/2)

y − y1 = m(x − x1)

[tex]y-\frac{1}{2} =\frac{3}{4} (x-1)[/tex]

[tex]y-\frac{1}{2} = \frac{3}{4}x-\frac{3}{4}[/tex]

Step-by-step explanation:

2 gets cancelled and it is 7/4

2 x 7/8= 7/4
2 Is the greatest common factor, therefore you’d cancel out the 8 by dividing it by 2. since 2/2=1 you can leave it and 8/2=4 therefore your answer is 7/4. hope this helped your confidence !

Erik used the Factor Theorem to find the remainder of 2x3-4x2-28x+6 divided by x+3. If he calculated the remainder to be 0, what does that tell him?

Answers

Step-by-step explanation:

x + 3 = 0

x = - 3

f(x) = 2x³ - 4x² - 28x + 6

f(- 3) = 2(- 3)³ - 4(- 3)² - 28 x (- 3) + 6

= 2 x (- 27) - (4 x 9) + 84 + 6

= - 54 - 36 + 90

= - 90 + 90

= 0

Therefore,

x + 3 is factor of 2x³ - 4x² - 28x + 6

In this assignment, you will need to design a complete Black-Box testing plan for the following program. A computer science student has to travel from home to ODU every day for class. After showing up to class late too many times due to traffic, the student made a program to tell him when he should leave the house. The time given depends on the class time and the day of the week.He came up with a few rules to make sure he gets to class on time.The normal drive time for this student is 30 minutes without traffic. He then gives himself 5 minutes to walk across campus to class from the parking lot.However, if he leaves home during the worst morning rush hour, from 6 AM - 7 AM on a weekday, he needs to add 20 minutes to his commute to account for traffic. If he leaves home during the regular morning rush hour, from 7 AM - 8 AM on a weekday, he needs to add 10 minutes to his commute to account for traffic.Mondays have the worst morning traffic, and he should instead add 30 minutes for 6 AM-7AM and 20 minutes for 7 AM 8 AM.On Saturdays and Sundays the student needs to take a different route due to road construction. This adds 6 minutes of travel time.If he leaves during the afternoon rush hour on a weekday, traffic from 4-6PM should add 15 minutes of travel time. Traffic in the afternoon is worst on Thursdays, and should instead add 20 minutes of travel time.If the class is between 9:30 AM and 11 AM he needs to arrive 10 minutes earlier for walking time because the closest parking lots are all full.The program will read data from the screen in the following format:Day_of_the_week hours:minutes AM/PMe.g.Tuesday 12:45 AMSunday 01:52 PMIf the input is not in the correct format the program will prompt the user again for the input.
