Answer: $2.55
Step-by-step explanation:
He bought the second shirt for half off the first shirt's price. He therefore bought it at:
= 19.99/2
= $10.00
Total paid for both shirts is therefore:
= 19.99 + 10
= $29.99
Sales tax is 8.5% so he paid:
= 29.99 * 8.5%
= 2.54915
= $2.55
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
The value decreases $187.5 a year, hope it helps, please let me know if im right
Answer:
-
- The cost of surfing the web at the café for one hour:
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
Take two points and substitute them into the formula for calculate the slope (The formula is 
).
Having these points:
and 
You can identify that:
Then, the slope is:
Substitute the slope and the coordinates of any point on the line into the equation and then solve for "b":
Therefore, equation in Slope-Intercept form that represents the function is:
Since 1 hour hour has 60 minutes, you need to substitute 
into the equation and then evaluate, in order to find the cost of surfing the web at the café for one hour. Then:
Answer:
The slope will be 1 so one point down and one up.
The y-intercept is -2.
Step-by-step explanation:
s=slope
i=intercept
y=s*x+i
