Answer:
The surface area is 10.26 feet.
Step-by-step explanation:
A=lw+l(w
2)2+h2+w(l
2)2+h2=0.8·0.8+0.8·(0.8
2)2+62+0.8·(0.8
2)2+62≈10.26131
lets solve for x
flip the equation
add-4 to both sides
divide both sides by 3
x=1/3y+-4/3
Answer:
The answer to this is A.) 8/17
Answer:
f(x) = -5/9 x + 5 1/9
Step-by-step explanation:
f(2)=4 and f(−7)=9 means the line pass through (2,4) and (- 7,9)
f(x) = mx + b
m = (y-y') / (x-x') = (9 - 4) / (- 7 - 2) = - 5/9
for (2,4) : b = f(x) - mx = y - mx = 4 - (- 5/9) x 2 = 4 + 10/9 = 46/9 = 5 1/9
f(x) = -5/9 x + 5 1/9
check for (-7, 9) f(-7) = (-5/9) * (-7) + 5 1/9 = 35/9 + 46/9 = 81/9 = 9
