Question 13
A person standing close to the edge on top of a 32-foot building throws a ball vertically upward. The
quadratic function h(t) = – 16ť? + 56+ + 32 models the ball's height about the ground, h(t), in feet,
seconds after it was thrown.
What is the height of the ball 4 seconds after its thrown?
feet

step-by-step explanation:

hello! just here for points! though i wish i knew!

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.

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
