Answer:

The answer to your question is    166 = 2l + 2w    and    l = 4w + 3

Step-by-step explanation:

Data

Perimeter = 166 ft

length of the garden = 4 times the width + 3 feet

Process

1.- Write an equation to find length and width using the perimeter

Perimeter of a rectangle = 2l + 2w

-Substitution

                                  166 = 2l + 2w         Equation l

2.- Write an equation comparing the two sides of the rectangle

                                     l = 4w + 3             Equation ll

The solution set for the last equation represents the set of all days when the towns have the same average high temperature.

  • The hotness of matter or radiation is expressed by the physical quantity known as temperature. The average air temperature for a specific time period, often a day, a month, or a year, as measured by a thermometer that has been properly exposed.
  • P(t) is the average high temperature, in degrees Celsius, of Paityn's town on t days.

       \begin{aligned} P(t)&=22.5+7.5\cos\left(\dfrac{2\pi (t-28)}{365}\right)\\\\  \end{aligned}

  • V(t) is the average high temperature, in degrees Celsius, of Vince's town on t days.

        \\ V(t)&=30.5+1.5\cos\left(\dfrac{2\pi (t-90)}{365}\right)

  • So, P(t) = V(t) represents the set of all the days when both towns have the same average high temperature.

Answer:

The unit vector u is (-5/√29) i - (2/√29) j

Step-by-step explanation:

* Lets revise the meaning of unit vector

- The unit vector is the vector ÷ the magnitude of the vector

- If the vector w = xi + yj

- Its magnitude IwI = √(x² + y²) ⇒ the length of the vector w

- The unit vector u in the direction of w is u = w/IwI

- The unit vector u = (xi + yj)/√(x² + y²)

- The unit vector u = [x/√(x² + y²)] i + [y/√(x² + y²)] j

* Now lets solve the problem

∵ v = -5i - 2j

∴ IvI = √[(-5)² +(-2)²] = √[25 + 4] = √29

- The unit vector u = v/IvI

∴ u = (-5i - 2j)/√29 ⇒ spilt the terms

∴ u = (-5/√29) i - (2/√29) j

* The unit vector u is (-5/√29) i - (2/√29) j
