The equation that models the table is a) y = -4x + 1.
Answer:
40cm
Step-by-step explanation:
The formula to find the circumference is :
<h3>C = π × d</h3>
Here,
d ⇒ diameter
Given that,
Circumference = 125.6cm
<u><em>Now let us find the diameter of the circle.</em></u>
C = π × d
125.6 = 3.14 d
Divide both sides by 3.14.
<u>40 cm </u>= diameter
Answer:
72
Step-by-step explanation:
Answer:
A) The fish was out of water for 0.6875 seconds.
B) Maximum height = 5.672
Step-by-step explanation:
Height is modeled by;
y = -16t² + 11t
A) To find total time of the fish out of water, we need to find the x - intercept. That is the points where y = 0
So, 0 = -16t² + 11t
So the roots of this equation are;
t = 0 or 0.6875
Thus,the fish was out of water for 0.6875 seconds.
B) y = -16t² + 11t
The x coordinate of the vertex is at - b/2a
For y = -16t² + 11t
a = -16, b = 11, c = 0
So, -b/2a = -11/(2*-16) = 11/32
The maximum height will be at the y-coordinate of the vertex.
Thus, we need to find f(11/32)
f(11/32) = -16(11/32)² + 11(11/32) = 1.890625 + 3.78125 = 5.671875 ≈ 5.672
