find the instantaneous speed of the bundle at t=3 seconds.

h(t) = 400 - 16t^2

suppose the bundle can withstand the impact of hitting the ground only for speeds up to 165 feet per second. to determine whether the bundle will survive the fall, you need to find out how fast it is traveling when it hits the ground.

investment b is an ordinary annuity with $3,909.64 in the account after one year.

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.

it goes right
