The answer would be C
Step-by-step explanation:
He started at 250 lbs. He is losing 3 lbs every week.
So it would be y=250(beginning weight)-3x(how much he's losing every week)
Hope this helped :)
Answer:
Conversely, given a pair of parametric equations with parameter t, the set of points (f(t), g(t)) form a curve in the plane.
As an example, the graph of any function can be parameterized. For, if y = f(x) then let t = x so that
x = t, y = f(t).
is a pair of parametric equations with parameter t whose graph is identical to that of the function. The domain of the parametric equations is the same as the domain of f.
Example The parametric equations
x = t, y = t2
Answer:
5.2 x 10^-2
Step-by-step explanation:
Scientific notation is used to simplify very large or very small numbers.
The formula for scientific notation is (a x 10^ n)
(a) is a number that is both greater than 1 and less than 10
(n) is the number of places the decimal place moves. This number can be positive or negative depending on the number you are converting. If the original number is greater than 1 (n) will be positive, and if the number is less than 1 (n) will be negative.
First you should write out the number.
0.052
Then, you should determine the number places the decimal point must move, and create a number greater than 1 and less than 10. (You should also pay attention to the direction the decimal point moves)
For this problem you will move the decimal place 2 places to the right to create the number 5.2.
Last, substitute the values into the formula. For this problem (a)= 5.2 and (n)= -2. This gives us the expression 5.2 x 10^-2.
