The measure of angel O is 42 degrees
pshichka [43]3 years ago
3 0

Answer:

19 degrees

Step-by-step explanation:

The measure of angle O is found by dividing the difference of the intercepted arcs.  In this case (arc MQ - arc NP)/2 = the measure of angle O.

(50 - 12)/2 = 38/2=19

The sum of two numbers is equal to 495. The last digit of one of them is zero. If you cross the zero off the first number you wi
Firdavs [7]

Answer:

45 and 450

Step-by-step explanation:

let x be the bigger number and y the smaller number, then:

495 = x+y, 10y=x

then you simplify:

495=10y+y

y=45

x=10y=450

Write the equation of the circle whose center is (-4,8) and has a diameter of 18
svetoff [14.1K]

Answer:

(x + 4)^2 + (y - 8)^2 = 81

or

(x + 4)^2 + (y - 8)^2 = 9^2 depending on how your teacher wants it written.

Step-by-step explanation:

The standard form for a circle is

(x + h)^2 + (y + k)^2 = r^2

r is the radius.

You are given the diameter

r = d/2

r = 18/2

r = 9

So you already have the right hand side of the equation

(x + h)^2 + (y + k)^2 = 9*2

(x + h)^2 + (y + k)^2 = 81

You basically have h and k as well. They come from the center point.

h = 4

k = - 8

So the equation of the circle (and the answer) is

(x + 4)^2 + (y - 8)^2 = 81

One question remains. Why do the x and y values change signs? If you know what the distance formula is, then what you are finding is the distance r of all points on the circle from the center of the circle.

It is the distance formula that is actually the formula for the circle.

How many ways can a 7 question multiple choice test be answered? (assume that there are 5 possible responses per question?
sweet [91]
I am assuming that you can only pick one answer per question.

Let's imagine there are two questions on the test. I would:

1) Consider the first question. How many possible ways could you answer it?

2) Consider the second question. How many ways can you answer that?

If you wrote out all the possibilities, how many combinations of answers would you get across the two questions?
