Since t is from 0 to 1 second, the time length is 1 second total.

replace t in the given equation with 1 and solve for x:

x = 4 cos(PI x 1 + PI/4)

X = 4cos(PI + PI/4)

x = 4cos(5PI/4)

x = 4(-cos(PI/4))

x = -2√2

I’m stuck on this problem plz help
Furkat [3]

Answer:

408 in²

Step-by-step explanation:

A rectangular prism has 6 rectangular faces.

Opposite faces are congruent

2 faces at (6 × 9) = 2 × 54 = 108 in²

2 faces at (9 × 10) = 2 × 90 = 180 in²

2 faces at (6 × 10) = 2 × 60 = 120 in²

surface area = 108 + 180 + 120 = 408 in²

The cost for renting a weed trimmer varies directly with the number of hours used. A weed trimmer rented for 5 hours costs $32.5
wlad13 [49]
Let the cost for renting be y and the number of hours be x
then:
y=kx
where:
k is the constant of proportionality
k=y/x
y=$32.5 when x=5 hours
thus;
k=32.5/5
k=6.5
hence the equation is:
y=6.5x
thus the value of y when x=8 hours will be:
y=6.5(8)=$52
Answer:'

<span>A y = $6.5x, y = $52.00</span>
