Angle C is inscribed in circle O. AB is a diameter of circle O. What is the radius of circle O?

vova2212 [387]

Answer:

radius = 5 units

Step-by-step explanation:

leg lengths of 6 and 8

AC = 6

BC = 8

Notice that since AB = diameter of circle and that C is inscribed in circle O

angle C = 90 degrees

triangle ABC is a right triangle

(AB )^2 = (AC)^2 + (BC)^2 by Pythagorean theorem

(AB)^2 = 6^2 + 8^2 = 36 + 64 = 100

AB = square root of 100 = 10

so AO = (1/2) *AB = (1/2)*10 = 5

What are the solutions to 16x^2-12x=54? Select all the apply.

lesya692 [45]

Answer:

-3/2 or 9/4

Step-by-step explanation:

16x^2 - 12x = 54

Now, we take 54 to the left side. It leads the right side to become "0". As 54 is a positive, it will negative as we change the side.

16x^2 - 12x - 54 = 0

Dividing both the sides by 2, we get,

8x^2 - 6x - 27 = 0

Now, we use factorization method,

8x^2 + 12x - 18x - 27 = 0

or, 4x (2x + 3) - 9 (2x + 3) = 0

or, (2x + 3) (4x - 9) = 0

Now, 2x + 3 = 0; or, 4x - 9 = 0

2x = - 3; or, 4x = 9 (changing the sides)

or, x = - (3÷2); or, x = (9÷4)

Therefore, the solution set for x is either - 3/2 or 9/4

For the function f(x)=2−3x, find f(4).<br><br> A −10<br><br> B −5<br><br> C 12<br><br> D 14

lukranit [14]

Answer:

<h2>The answer is option A</h2>

Step-by-step explanation:

$f(x)=2−3x$

To find f(4) , substitute the value of x that's 4 into f(x). That is for every x in f(x) replace it with 4.

We have

f(4) = 2 - 3(4)

= 2 - 12

We have the final answer as

Hope this helps you
