Answer:

minimum -45, maximum 32

Step-by-step explanation:

C=4x-3y

x≥0, y≥4, x+y≤15

Maximum value of C can be achieved at max x and min y

min y=4 => max x=15-4=11

C=4*11-3*4= 32

Minimum value of C can be achieved at min x and max y

min x=0, max y =15

C=4*0-3*15= -45

So answer is minimum -45, maximum 32

Answer:

x = 22 mm

Step-by-step explanation:

The area of a kite is one-half of the product of the max width and max height.

A = (1/2)(a)(b)

We are given the height and the area, and need to find the width. Plug in the given values and solve.

247.5 = (1/2)(22.5)(b)

495 = (22.5)(b) (multiply both sides by 2 to get rid of the fraction)

22 = b (divide both sides by 22.5 to isolate b)

The width is 22 mm across

Lana71 [14]

Answer:

Part A). 25 feet

Part B). 16.25 feet

Step-by-step explanation:

Part A). By applying Pythagoras theorem in ΔABC,

AC² = AB² + BC²

AC² = (24)² + 7²

AC² = 576 + 49

AC = √625

= 25 feet

Part B). By applying Pythagoras theorem in ΔABC,

AC² = AB² + BC²

(25)² = (19)² + x²

625 = 361 + x²

x² = 625 - 361

x = √264

x = 16.25 feet

Sergio [31]

<h3>Hello there i hope you are having a good day :) Question :A person began running due east and covered 15 kilometres in 2.0 hours. What is the average velocity of the person? Show all your work: = </h3><h3>So firstly you would do D = distance the total displacement of the person running due east that would equal too = 15 km. Then you would do time it was taken to the person to travel the given distance due east which would be = 2.0 hr. Then finally you would do v velocity that you would do average velocity = total displacement/total time so that would be v = 15 km/2.0 hr v = 7.50 km/h and that would be your answer.</h3><h3>Hopefully that helps you.</h3>
