Find the linear velocity of a point on the edge of a wheel rotating 48 times per minute. The diameter of the wheel is 27 inches.
A. 339 ft/min
B. 221 ft/min
C. 453 ft/min
D. 108 ft/min

i believe that the slope of the line is -5

step-by-step explanation:

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.

i   want to say the correct answer is 12,000 correct me if i'm wrong

total amount spent on toll=$1.75 each(two in number i.e at two tolls)

                                              =1.75×2=$3.50

amount spent on gas station for filling up the gas =$ 28

suppose amount spent on two tolls and amount spent on gas station for filling the gas are two solution of an algebraic expression.

now , writing in terms of algebraic expression

⇒(x-3.50)(x-28)

⇒(x-7/2)(x-28)

⇒x(x-28)-7/2(x-28)

⇒x²-28 x-7/2 x-

⇒x²- +98

terms are, x²,-,98

coefficient of x²=1

coefficient of x= =-1/2×7×3×3×x

constant term=98=7×7×2

coefficients of the algebraic expression that represents the total cost of gas and tolls=-[coefficient of x]=63/2=28 [amount spent on gas] +3.50 [amount spent on toll]=$31.50
