The x coordinate of X and X' has to be the same. T<span>he coordinates of X is (4,5) so its distance to y=1 is 5 - 1 = 4. T</span>he distance from X' to y=1 must also be 4. T<span>he distance from -3 to 1 is 4. So, the answer for the given question above is (4,-3). I hope this helps.</span>

A 1939 Ford heads out of town traveling at 40 mph. Three hours later a 1957 Chevy follows traveling at 70 mph. How long will it
slavikrds [6]

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

A sinusoidal function whose period is 1/2, maximum value is 10, and minimum value is -4, has a y-intercept of 3. What is the equ
nikdorinn [45]
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: sin( \frac{x}{4 \pi })

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:

7sin( \frac{x}{4 \pi } )

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

y=7sin( \frac{x}{4 \pi } )+k

The y-intercept is 3. This means for x=0, y=3. Using the values, we get:

3=7sin(0)+k \\  \\ &#10;3=k

Thus the equation of the sinusoidal function becomes:

y=7sin( \frac{x}{4 \pi } )+3

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

A rectangle has an area of 50X5Y5 and a length of 25X3Y which of the following represents the width of a triangle
Rufina [12.5K]

Answer:

2x²y⁴

Step-by-step explanation:

Area = W × L

W = A / L = \frac{50x^5y^5}{25x^3y} = 2x²y⁴
