The formula for centripetal acceleration, a, is given by this formula, where v is the velocity of the object and r is the object’s distance from the center of the circular path: a=v^2/r . Solve the formula for r.

Answers

Answer 1
Answer:

Answer:

r = V^2/a

Step-by-step explanation:

Here, we want to write the formula for r

What this simply mean is that we want to make r the formula subject

We have this as follows;

a = V^2/r

r = V^2/a

The price of an item has dropped to $102 today. Yesterday it was $120. Find the percentage decrease.

Answers

Using cross multiplication, 102/120=x/100 ---> 120x=10200 divide the entire problem by 120 ---> 85. 102 is 85% of 120, so the item has dropped in price by 15%

Final answer:

The decrease in price is $18. The percentage decrease is calculated by dividing the decrease by the original price and multiplying by 100, which results in a 15% decrease.

Explanation:

The problem involves finding the percentage decrease of a price from $120 to $102. The first step is to find out how much the price decreased. This involves subtracting the new price ($102) from the original price ($120), which gives us an amount of $18. Now, the percentage decrease is computed by dividing this decrease ($18) by the original price ($120) and multiplying the result by 100. Hence, Percentage decrease = ($18 / $120) * 100% = 15%.

Therefore, the price has decreased by 15% from yesterday to today.

HELP ASAP PLEASE!!!Explain how to tell if a point is a solution for a system of equations.

Answers

Explanation:

When you put the solution values into each equation, the equation becomes a true statement. If all equations become true statements, the point is a solution to the system.

_____

For example, consider the system of equations ...

  • x + y = 6
  • x - y = 4

The point (x, y) = (5, 1) is proposed as the solution. When we put those values into the equations, we get ...

  5 + 1 = 6 . . . . . true

  5 - 1 = 4 . . . . . .true

(x, y) = (5, 1) is the solution to this system of equations. (Since it is a system of two independent linear equations in an equal number of unknowns, we know there is only one solution.)
