Abullet is shot upwards with an initial velocity of 1000 ft/sec from a
point 10 ft above the ground, and its height above the ground at time t
is given by h(t) = -160 + 1000 + 10
i. how high will the bullet go?
ii. how long will it take the bullet to reach the highest point?

step-by-step explanation: easy math

answer: 1+1

step-by-step explanation: 1+1 is at least 2

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)

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
