The residual value when x = 4 is 6.72 if the line of best fit to be y = 2.78x – 4.4

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more number and variables.

Given the function:

y = 2.78x - 4.4

When x = 4:

y = 2.78(4) - 4.4 = 6.72

The residual value when x = 4 is 6.72 if the line of best fit to be y = 2.78x – 4.4

Write an equation of the line that passes through the given point and has the given slope.
ycow [4]

Answer:

y = 1/2x + 1

Step-by-step explanation:

m = 1/2

Slope-intercept:

y - y1 = m(x - x1)

y - 3 = 1/2(x - 4)

y - 3 = 1/2x - 2

y = 1/2x + 1

An airplane is traveling due east with a velocity of 583 miles per hour. The wind blows at 75 miles per hour at an angle of S58°
ASHA 777 [7]

Answer:

  D. 647.8 miles per hour; S86.5°E

Step-by-step explanation:

We assume the wind direction is supposed to be S58°E. Then the bearing of the plane measured clockwise from north is 90°, and the direction the wind is blowing toward has a bearing of 122°. The resultant speed and direction is the sum of the two vectors, which is easily found using a suitable calculator:

  583∠90° + 75∠122° = 647.8∠93.5°

The bearing of 93.5° translates to the direction S86.5°E.

_____

An angle east of south is subtracted from 180° (south) to find the equivalent bearing.
