Work out 25% of 20 metres

Answers

Answer:

5 meters

Step-by-step explanation:

We have to calculate 25% of 20 meters

So we rewrite the equation

25% × 20

$(25)/(100)$ × 20

0.25 × 20

= 5 meters

25% of 20 meters is 5 meters

Final answer:

The question pertains to finding theclosest point on a plane to a specific point and determining the local extremum points of a function using differential calculus. Due to word limitations, a step-by-step solution couldn't be provided.

Explanation:

The subject of this question is Mathematics, specifically it deals with the concepts of planes in three-dimensional space and finding local extremum points of a function. Firstly, to find the point on the plane x - 2y + 3z = 12 closest to the point (0, 2, 2), we can use the perpendicular distance formula from a point to a plane. To find the local maximum, minimum values and the saddle points of the function F(x, y) = -y − by cos(x), differential calculus should be used. Unfortunately, this requires more than 100 words, therefore I am unable to provide a step-by-step solution here.
