Given : y = -25 and x = -5
We can notice that if we Multiply 'x' with 5 we get 'y'
That is (-5) × 5 = -25
⇒ x multiplied by 5 = y
(a) The Equation that relates x and y is 5x = y
(b) We found that the Equation of this Direct variation is : 5x = y
The Question is to find the value of y when x = 3
The Value of y at x = 3 can be found by simply substituting x = 3 in the equation we found.
⇒ y = 5x
⇒ y = 5 × 3
⇒ y = 15
So, the Value of y when x = 3 is 15
Answer: The death is 500, there will be 125 carbon-14 atoms, and after 25,000 years.
Step-by-step explanation:
I just took a test and got it right, I can't do math (;
In order to be perpendicular, you must have a slope that is the opposite reciprocal, so the slope should by -3/4. So the equation could be y = -3/4x with any other number at the end.

Step-by-step explanation:
use the pythagorean theorem to find the height of the cone

you get a = 8
the formula for the volume of a cone is

plug in 6 for the radius and 8 for the height. then solve
