Answer:
The ball travel horizontally 37 feet before it hits the ground
Step-by-step explanation:
we have
where
x ----> is the horizontal distance in feet
A ---> is the altitude of the ball, in feet.
we know that
When the ball hit the ground, the altitude of the ball is equal to zero
so
For A(x)=0
solve the quadratic equation
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
therefore
The ball travel horizontally 37 feet before it hits the ground

The 4C matrix is obtained when all elements of matrix C are multiplied by 4. It <span>has all the same elements as C, only multiplied by 4.
Let's analyze all matrices
A. Not all elements of A can be divided by 4 (3 can not be divided by 4, the solution is not a whole number).
B. All elements of matrix B can be divided by 4, which means that B is a $C matrix (there is a matrix C which multiplied by 4 gives the matrix B).
C. Not all elements of C can be divided by 4.
D. Not all elements of D can be divided by 4.
Solution: B
