Step-by-step explanation:

time ∝ number of door 1

time . ∝ 1/number of people. 2

compare equation 1 and 2

time . ∝ number of door / number of people

put k as constant

time = k number of door / number of people. 3

time =2. people=4 door = 10

putting in equation 3

2 = k (10)/(4)

2×4/10 = k

8/10 =k

4/5 =k

putting in equation 3

time= 4/5 number of door / number of people

now time =5 door= 25 people=?

5=4/5 (5)/ (number of people)

number of people =4/5 ×25/5

number of people= 4

Given f(x) = 6x^4 – 10x^3 + 40x – 50, find f(2)
ASHA 777 [7]
F(x)=6x^4-10x^3+40x-50, plug 2 in for x
f(2)=6(2)^4-10(3)^3+40(2)-50
f(2)=12^4-30^3+80-50
f(2)=20735-27,000+80-50
f(2)=-6,235
