Answer:
i believe the answer is A
Step-by-step explanation:
(y + 4) = -(1)/(3)(x + 1)
distribute -1/3 to (x+1)
(y+4)= -1/3x + -1/3
subtract 4 from each side
y= -1/3x - 13/3
Answer:
0.0597in/s
Step-by-step explanation:
The volume of the spherical balloon V= 4/3πr³
r is the radius of the balloon
The rate at which the volume is changing dV/dt is expressed as;\
dV/dt = dV/dr*dr/dt
dV/dr = 3(4/3πr²)
dV/dr = 4πr²
dV/dr = 4π(2)²
dV/dr = 16π
dV/dt = 3 in³/s
Substitute inti the formula
3 = 16πdr/dt
dr/dt = 3/16π
dr/dt = 3/50.24
dr/dt = 0.0597in/s
Hence the balloon is increasing at the rate of 0.0597in/s
15.38. 7, the number in the hundredths place, is turned into 8 due to the following digit, 5. Since it is equal to the minimum, 5, the previous number is rounded up.
Hour each week:22.5
dollars earned every hour:8.25
dollars spent:61.50
it would take 7 weeks.
'Mile', 'yard', and 'foot' are measures of length or distance.
'Acre' is a measure of area. So they're not equivalent units.
1 Acre = 43,560 square feet,
4,840 square yards,
0.0015625 square mile .
6 Acres = 261,360 square feet,
29,040 square yards,
0.009375 square mile.
