Answer:
Option 4: x^2+y^2 = 52
Step-by-step explanation:
Given
Centre at origin
Point on circle = (-4, -6)
The distance between origin and point on circle will be the radius of the circle
So,
As the center is at origin the standard equation will be:
Putting the value of r
Hence, last option i.e. Option 4 is correct ..
Answer:
a = 2
Step-by-step explanation:
We can use cross products to solve
8 a
----- = -------
28 7
8*7 = 28*a
Divide each side by 28
56/28 = 28a/28
2 =a

There is nothing, thats your answer
Step-by-step explanation:
Hello there, and thank you for asking your question here on brainly.
Short answer: 74
Why?
We have two sets of parenthesis here, and we have to do the parenthesis inside of the other parenthesis, (called brackets) first. (11 - 2 = 9) Now multiply 9 by 5. (9 × 5 = 45) Multiply 45 by 2 . . . (45 × 2 = 90) Finally, subtract 90 by 16. (90 - 16 = 74)
Hope this helped you! ♥
