Answer:
0.3(8.2 x 10^-3) = 2.46 X 10 ^ -3
Step-by-step explanation:
We need to solve the equation 0.3(8.2 x 10^-3) and write answer in scientific notation.
Solving,
= 0.3(8.2 x 10^-3)
= 0.3 * 0.0082
= 0.00246
Writing in scientific notation
= 2.46 X 10 ^ -3
So, after solving the expression 0.3(8.2 x 10^-3) the result is 2.46 X 10 ^ -3.
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
