A circle is centered at the point (-7, -1) and passes through the point (8, 7).

Bess [88]

Answer:

Step-by-step explanation:

radius =( (8+7)^2 + (7+1)^2 )^1/2 = 17 unit

Equation of the circle = (x + 7)^2 + (y+1)^2 = 17^2

= (-15+7)^2 + (y+1)^2 = 17^2

=14

(-15, 14) lies on this circle

19. Use the unit circle to find the value of tan 315º.<br> Show work pls.

Free_Kalibri [48]

Answer: -1

Step-by-step explanation:

First change tan(315) to:

$\frac{\sin(315)}{\cos(315)}$

Then evaluate the sine and cosine function. What is the y component of 315 degrees? What is the x component of 315 degrees?

$-\frac{\sqrt{2} }{2} /\frac{\sqrt{2} }{2} =-1$

What is the circumference of circle p ? Express in terms of pie

SVETLANKA909090 [29]

The circumference of a circle is calculated using the following equation:

$C= \pi d$

Where d is equal to the diameter (the length of a straight line from one side of the circle to the other side).

We know that the diameter of the circle given (also known as AB) is equal to 20 cm.

We can then plug this into the equation and solve for the circumference:

$C= \pi (20)$

Since the question asks for the answer to be in terms of $\pi$ , this is as far as we need to go. So the circumference of the circle is: $20 \pi$ or D.

You are given the summer reading list for your English class. There are 8 books on the list. You decide you will read all. In ho

vekshin1

Consider for a moment building a tree with all possible choices. The first row would contain 8 books (each possible choice for the first book). Then, the second row would contain 7 books for each book in the first row (the choices possible for the second book). Otherwise, it would be 8*7. Following this principal, we continue to multiply down to 1. 8*7*6*5*4*3*2*1. This is also known as 8!, a factorial.
Finally, 8! = 40,320
