Jami is trying to model the movement of a tire. in order to properly model the movement, she is going to focus on the movement of the tire's air nozzle. the nozzle is on the right side of the tire and she is going to treat that position as the equilibrium position. she then slowly rotates the tire so that the nozzle goes up at the beginning of the rotation, and follows its change in height. the distance of the nozzle from the center of rotation is nine inches. she finds that it takes eight seconds for the tire to make a single revolution. which of the following functions best models the position of the nozzle? a-s(t)=9cos(4pit)b-s(t)=9sin(pi/4 t)c-s(t)=9cos(pi/4 t)d-s(t)=9sin(4pit

i do not know the answer

step-by-step explanation:

the equation is not included but the answer is (1.50, 2.00, 2.75)

step-by-step explanation:

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
