The fabric cost $181.875
Step-by-step explanation:
Blue fabric bought = 3 3/4 yards , change to improper fraction (4*3)+3/4 = 15/4 yards
Red fabric= 12 5/6 yards = 77/6 yards
Purple fabric= 7 2/3 yards= 23/3 yards
Find total length of fabric bought, 15/4 +77/6 +23/3 =291/12 yards
Cost per yard= $7.50
Total cost will be, 291/12 * 7.50 =$ 181.875

Step-by-step explanation:
Answer:
a) 13 m/s
b) (15 + h) m/s
c) 15 m/s
Step-by-step explanation:
if the location is
y=x²+3*x
then the average velocity from 3 to 7 is
Δy/Δx=[y(7)-y(3)]/(7-3)=[7²+3*7- (3²+3*3)]/4= 13 m/s
then the average velocity from x=6 to to x=6+h
Δy/Δx=[y(6+h)-y(6)]/(6+h-6)=[(6+h)²+3*(6+h)- (6²+3*6)]/h= (2*6*h+3*h+h²)/h=2*6+3= (15 + h) m/s
the instantaneous velocity can be found taking the limit of Δy/Δx when h→0. Then
when h→0 , limit Δy/Δx= (15 + h) m/s = 15 m/s
then v= 15 m/s
also can be found taking the derivative of y in x=6
v=dy/dx=2*x+3
for x=6
v=dy/dx=2*6+3 = 12+3=15 m/s
93.75 because 5.75x7.50=43.125 and 6.75x7.50=50.625 and 50.625+43.125=93.748 and round it to the near test hundredth because it’s money and that’s 93.75
Answer:
7, x, 5, and x
Step-by-step explanation:
factors are numbers or variables being multiplied by something else. 12 and 23 arent being multiplied by anything
