Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{10 \: N}}}}}

Step-by-step explanation:

Given,

Load distance ( LD ) = 2m

Load ( L ) = 800 N

Effort distance ( ED ) = 160 m

Effort ( E ) = ?

<u>Finding the Effort applied</u>

Apply the principal of simple machine :

\boxed{ \sf{L \times LD = E\times ED}}

\longrightarrow{ \sf{800  \times 2 = E \times 160}}

\longrightarrow{ \sf{1600 = 160 \: E}}

\longrightarrow{ \sf{160E = 1600}}

\longrightarrow{ \sf{ \frac{160E}{160}  =  \frac{1600}{160} }}

\longrightarrow{ \sf{E = 10 \: \: newton}}

Effort applied = 10 N

Hope I helped!

Best regards! :D

sesenic [268]

Answer:the minimum rate is 1 mile per hour.

Step-by-step explanation:

Chanita wants to swim the 21-mile English Channel in 48 hours. Total number of miles that she covered on the first day is 9 miles. Total distance left for her to cover would be

21 - 9 =12 miles.

The next day, she has 12 hours of daylight to complete the remaining distance. Let x represent the minimum rate she has to swim on the second day to complete the distance.

Speed = distance/time

Therefore,

x ≥ 12/12

x ≥ 1

F(x) = (x - 2)²(x+1)​
Inessa [10]

(x - 2)²(x+1)​

(x-2)(x-2)

multiply the two brackets together

(x)(x)=x^2

(x)(-2)=-2x

(-2)(x)=-2x

(-2)(-2)=4

x^2-2x-2x+4

x^2-4x+4

(x^2-4x+4)(x+1)

multiply the brackets together

(x^2)(x)=x^3

(x^2)(1)=x^2

(-4x)(x)=-4x^2

(-4x)(1)=-4x

(4)(1)=4

x^3+x^2-4x^2-4x+4x+4

Answer:

x^3-3x^2+4
