OlgaM077 [116]

Answer:

=17

Step-by-step explanation:

We need the slope and the y-intercept to find the equation of the linear model.

This line goes through (0,28) and (1,26), so the slope is

\frac{26 - 28}{1} = -2

1

26−28

​  =−2

The equation that best describes this model is

\widehat{y} = -2x + 28

y

​  =−2x+28

Plug in x = 5.5 in the above equation to get

​\widehat{y}

y

​   ​=−2x+28

=(−2)(5.5)+28

=−11+28

=17

Based on this equation, the date in April her flowers will bloom if the average temperature in March is

Use the unit circle tan (3/4)
Mariana [72]

Using the unit circle, the coordinates of 3π/4 is :

(-\frac{\sqrt[]{2}}{2},\frac{\sqrt[]{2}}{2})

Note that tangent function can be solved using the formula y/x

where x and y are the coordinates of the angle.

This will be :

\frac{\sqrt[]{2}}{2}\div(-\frac{\sqrt[]{2}}{2})=-1

The answer is -1

In an obstacle course, participants climb to the top of a tower and use a zip line to travel across a mud pit. The zip line exte
barxatty [35]

Using relations in a right triangle, it is found that the length of the zip line is of 40.4 feet.

<h3>What are the relations in a right triangle?</h3>

The relations in a right triangle are given as follows:

  • The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.
  • The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.
  • The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.

This situation can be modeled by a right triangle, in which the extension of the zip line of 48.2 feet is the hypotenuse and the length is the adjacent side to the angle of 33º, hence:

\cos{33^\circ} = \frac{l}{48.2}

l = 48.2 x cos(33º)

l = 40.4.

The length of the zip line is of 40.4 feet.
