4 hours
using the formula
distance = speed × time (t)
the Ford will have travelled 3 × 40 = 120 miles before the Chevy leaves
the Ford's distance can be modelled as
distance = 40t + 120
the Chevy's distance can be modelled as
distance = 70t
equating the right sides and solve for t
70 t = 40t + 120 ( subtract 40t from both sides )
30t = 120 ( divide both sides by 30 )
t = 4
the Chevy catches up with the Ford after 4 hours
Period of sin wave = 1/2
Period of parent sine function is 2π.
This means the x value of sine function (sin(x)) has to be divided by 4π to get a period of 1/2 because 2π/4π = 1/2
Thus, our function will be of the form:

Maximum Value = 10
Minimum Value = -4
Amplitude of the function = (Maximum Value - Minimum Value)/2
So, amplitude of the function is 7
Thus, the function will be of the form:

The function has a y-intercept other than zero, this means the function will be of the form:

The y-intercept is 3. This means for x=0, y=3. Using the values, we get:
Thus the equation of the sinusoidal function becomes:
3x - 2 = x + 1
2x = 3
x = 3/2
x = 1.5
3x - 2 = 3(1.5) - 2 = 2.5
or
x + 1 = 1.5 + 1 = 2.5
P = 4(2.5) = 10
perimeter of square is 10 cm so side of square = 2.5cm
Kinda late, but do you have the area of the triangle?
Answer:
2x²y⁴
Step-by-step explanation:
Area = W × L
W = A / L =
= 2x²y⁴
