Answer:
f(5) = 115
Given:
f(x) = x² - 11x + 30x -5
x⇒5
So,
f(x) = x² - 11x + 30x -5
f(5) = 5² - 11(5) + 30(5) -5
f(5) = 25 - 55 + 150 - 5
f(5) = 115
Answer:
هلا وغلا فيك يا قلبي الصغير لا يتحمل
We have to calculate the length of stack RM. This is a pyramid with a rectangular base. If TS = 12 cm, then OM = TS / 2 = 12 / 2 = 6 cm. And since we already know that RO = 15 cm, we will use the Pythagorean theorem: RM^2 = 15^2 + 6^2; RM^2 = 225 + 36 = 261; RM = sqrt ( 261 ) ; RM = 16.1555 ( or 16.2 rounded to the nearest tenth ). Answer: RM = 16.2 cm<span>.</span>
