A(b-c)=ab-ac
(1/7)(1/3h-1/2)=(1/7)(1/3h)-(1/7)(1/2)=1/21h-1/14
now we gots
6 and 1/7+1/21h-1/14
rearange
6 and 1/7-1/14+1/21h
make common denom which is 14
6 and 2/14-1/14+1/21h
6 and 1/14+1/21h
Answer:
1570
Step-by-step explanation:
the formula for surface area of a cylinder is:
A= 2πrh + 2πr²
π aka pi = 3.14
r = 10
h = 15
so now plug in the numbers
A = 2(3.14)(10)(15) + 2(3.14)(10²)
A = 942 + 2(3.14)(100)
A = 942 + 628
A = 1570
Answer:
y=4x+1
Step-by-step explanation:
to find the slope (m) you have to calculate what rise over run is for you table, in this table rise (y values) go up by 4 every time. so thats the numerator for your slope. the run is how much the x value goes up everytime, it goes up by 1 so the denomenator is 1, this simplifies to 4 so m= 4. the y intercept (b) is the y point where x equals zero so it is 1. x and y are simply variables used when graphing so they have no set values.
