Angle A is circumscribed about circle O. What is the measure of D?

Mathematics

Mariana [72]3 years ago

Answer:

m<D=50

Step-by-step explanation:

The reason is that ABOC is a quadrilateral, so its angle add up to 360*. Each of the tangent angles, <ABO and <ACO, has a measure of 90*.

m<ABO + m<ACO + m<A + m<O = 360

90 + 90 + m<A + m<O = 360

m<A + m<O = 180

80 + m<O =180

m<O = 100

If the measure of central angle <O is 100*, what is the measure of inscribed <D?

The measure of a central angle is equal to the measure of the arc it intercepts. If m<O = 100*, then m BC = 100.

The measure of an inscribed angle is half of the measure of the arc it intercepts. If m BC = 100*, then m<D = 50

m<D=50

Answer:

B] f(n) = 6(3)n − 1; f(5) = 486

Step-by-step explanation:

First, you have to identify which type of relation the points have. From the graph you can tell that it's an exponential growth. The x values change in the same amount every time, in this case by 1.

So if the relation is exponential, if we divide the y coordinates you should get the same result every time.

18 / 6 = 3

54 / 18 = 3

162 / 54 = 3

So the y value increases 3 times. That means that the next value should be 162*3 = 486.

Which system is equivalent to the system shown and could be used to solve the system of equations correctly using the eliminatio
Bumek [7]

Answer:

The solution is (2, -2)

Step-by-step explanation:

In order to solve this, multiply the second equation by -5 and then add through.

5x - 4y = 18

-5x - 15y = 20

------------------

-19y = 38

y = -2

Now that we have the value of y, we can solve for x.

x + 3y = -4

x + 3(-2) = -4

x - 6 = -4

x = 2

Can someone help me with this question? Thank you! ​
Natali [406]

Answer:

11

Step-by-step explanation:

22 is the largest number you are given in this diagram. 0 is the smallest. that would be your first step.

Next think about it as if you already know your midpoint, as in, midpoint being half of your ending value.

Lastly, you want to divide 22 in half, since midpoint is half of your line segment, and then answer you get is 11

What is the fewest number of quarters, nickels, and pennies that can be fairly exchanged for 2 quarters, 6 nickels, and 9 pennie
adoni [48]

Answer:

Your answer is 3 quarters, 2 nickels, and 4 pennies

Step-by-step explanation:

2 quarters plus 6 nickels plus 9 pennies is equal to 89 cents. So if we subtract 75(3 quarters) we get 14 which is less than 25 therefore we must only use nickels and pennies from now on. If we take 14 and subtract 10(2 nickels) we get 4 which less than 5 leaving us only to use pennies, which one a piece so it must be 4 pennies. Hope this helps!

For (x)=3x+1 and g(x)=x^2 -6, find (f+g)(x)
julsineya [31]

Answer:

<h2>(f + g)(x) = x² + 3x - 5</h2>

Step-by-step explanation:

(f+g)(x)=f(x)+g(x)\\\\f(x)=3x+1;\ g(x)=x^2-6\\\\(f+g)(x)=(3x+1)+(x^2-6)=x^2+3x+1-6=x^2+3x-5
