Step-by-step explanation:
Because a rectangle has four sides and the opposite sides are the same length, you can simply multiply each of the given sides (5 5/8 feet and 6 1/4 feet) by 2, and then add them together.
5 5/8 × 2 = 11 1/4.
6 1/4 × 2 = 12 1/2
11 1/4 + 12 1/2 = 23 3/4 or 23.75
Therefore, the perimeter of the rectangle is 23.75 feet.
For perpendicular lines, m2 = -1/m1.
For line -x + 5y = 14 => 5y = x + 14 => y = 1/5 x + 14/5 => slope = 1/5
m2 = -1 / (1/5) = -5
Required equation is y - (-2) = -5(x - (-5))
y + 2 = -5(x + 5)
5x + y = -25 - 2
5x + y = -27
Answer:
Now I am not completely sure but...maybe is it that:
A quadratic regression is the process of finding the equation of the parabola that best fits a set of data. As a result, we get an equation of the form:
y = a x 2 + b x + c where a ≠ 0 .
Cause I think it might be the best way to find this equation manually is by using the least squares method. That is, we need to find the values of a , b , and c such that the squared vertical distance between each point ( x i , y i ) and the quadratic curve y = a x 2 + b x + c is minimal.
The matrix equation for the quadratic curve is given by:
[ ∑ x i 4 ∑ x i 3 ∑ x i 2 ∑ x i 3 ∑ x i 2 ∑ x i ∑ x i 2 ∑ x i n ] [ a b c ] = [ ∑ x i 2 y i ∑ x i y i ∑ y i ]
Answer:
420 miles
Step-by-step explanation:
Distance traveled per hour = 55 miles
Distance traveled in 6 hours = 55 * 6 = 330 miles
Distance of the trip = 330 + 90 = 420 miles
