Answer:
y intercept (0;4)
Step-by-step explanation:
let x = 0 because the graph will intersect the y-axis at the value of 0 for the x-axis
Answer:
y = -2x - 5
Step-by-step explanation:
Set the slope of the given equation to the reciprocal to get a perpendicular slope:
y = 1/2x --> -2x
y = -2x + b will be your current equation. To get b, you must insert the given information: (-1, -3)
-3 = -2 (-1) + b
Solve:
-3 = 2 + b
<u>-2 -2 </u>
-5 = b
Thus your equation would be y = -2x - 5.
Answer:
40 ft, max height
Step-by-step explanation:
Nick tossed a penny off a 20 foot bridge.
The path of the penny's height can be modeled by the equation h(t) = -16t^2 + 40t + 20.
Find the maximum height of the penny.
