For this case we have the following function:

To find the zeros of the function we make
and solve for "x", then:

We multiply by -1 on both sides of the equation:

We factor the equation, for this we look for two numbers that, when multiplied, result in 36 and when added, result in -13. These numbers are -9 and -4.

Thus, the factored equation is:

Therefore, the roots are:

Answer:

Answer:
847.8 sq meters
Step-by-step explanation:
Formula:
A= 2πrh + 2πr^2
A= 2(3.14)(9)(6) + 2(3.14)9^2
A= 339.12 + 508.68
A= 847.8

Answer:
where x denotes number of small rooms and y denotes number of large rooms
Step-by-step explanation:
Given: Small rooms can hold 3 people, and large rooms can hold 4 people.
Number of small rooms is twice the number of large rooms.
Small rooms and large rooms altogether can accommodate 70 guests.
To find: system of equations that could be used to determine the number of small rooms reserved and the number of large rooms reserved
Solution:
Let x denotes number of small rooms and y denotes number of large rooms.
As number of small rooms is twice the number of large rooms,

As small rooms and large rooms altogether can accommodate 70 guests such that small rooms can hold 3 people, and large rooms can hold 4 people,
