Review the graph. On a coordinate plane, a vector labeled 26 miles per hour goes from (0, 0) to a point labeled hand glider in quadrant 4. The angle between the vector and x-axis is 60 degrees. A hand glider dives at 25 mph in a direction 60° below horizontal. What is the component form of the velocity vector? (StartFraction 25 Over 2 EndFraction, StartFraction 25 StartRoot 3 EndRoot Over 2 EndFraction) (StartFraction 25 Over 2 EndFraction, negative StartFraction 25 StartRoot 3 EndRoot Over 2 EndFraction) (negative StartFraction 25 Over 2 EndFraction, StartFraction 25 StartRoot 3 EndRoot Over 2 EndFraction) (negative StartFraction 25 Over 2 EndFraction, negative StartFraction 25 StartRoot 3 EndRoot Over 2 EndFraction)

answer: 1inch=7days  

12inch=12*7=84days

step-by-step explanation:

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
