Answer:

$Period=3$

Step-by-step explanation:

we know that

The period of a periodic function is the interval of x-values on which the cycle of the graph that's repeated in both directions lies.

see the attached figure to better understand the problem

To calculate the period subtract $1.5$ from $4.5$

$Period=4.5-1.5=3$

The "period" of a repeating function is the change in x between consecutive identical values...in this case 3 units.

Judy is pulling on a trunk with a 12-N force. Ike pulls at right angles to Judy. With how much force must Ike pull to make the r

Ratling [72]

To understand the problem, let's first draw a free body diagram of the forces exerted by Judy and Ike on the truck. (Refer to the left side of the attachment).

To solve for the resultant, we just use the tip-to-tail method. This is illustrated on the right side of the attachment.

We can see that the tip-to-tail method forms a right triangle thus we can just apply the Pythagorean theorem in solving for Ike's force.

$20^{2} = 12^{2} + F^{2}$
$400 = 144 + F^{2}$
$256 = F^{2}$
$F = 16.0$

ANSWER: Ike must pull the truck with a force of 16.0 N.
