Answer:
I have a answer for the second question. The better buy would be 69 cents for 18in. I say this because in each foot there is 12 in right, 18 in is a foot and 6 in. if you buy two 18 in wires it will cost $1.38 for 3 feet of wire which is cheaper then $1.49.
Step-by-step explanation:
The 3 has no relation to time. Therefore, it is the starting position of the ball. Since the expression is the height, in feet, of the ball above the ground, the 3 means that the ball started 3 feet above ground when thrown.
For future knowledge, the t^2 means that -16 is the initial acceleration of the ball, and the t means that 40 is initial velocity.
By using the general formula for a reflection across the x-axis, we will see that the new coordinates of the center are (-3, -4)
<h3>
Where will be the center of the new circle?</h3>
For any point (x, y), if we perform a reflection across the x-axis, the only thing we are doing is changing the sign of the y-component.
So the reflection is:
(x, y) → (x, -y)
In this case, we are reflection a circle whose center is (-3, 4), so the new coordinates of the center of the circle are:
(-3, 4) → (-3, -4)
The center of the reflected circle is at (-3, -4)
