the solution to 0 < (x+144) (x+67) is 

For the construction of a deck surrounding a bay window, Tricia must cut several boards at an angle of 120°. Setting up her mitre saw, she sets and angle of 30°. Will this cut the wood at the correct angle? If not, what angle should she use if her mitre saw can only be moved up to 90°.

Determine the numbers of terms, n, and the sum, Sn, of the following series. 5+13+21+...+149.

the seventh term of an arithmetic sequence is 64 and the twenty sixth is 235. what is the sum of the first 15 terms

An object falls with an acceleration of a= -9.81 m/s^2. A function relating the height from which the object falls, the initial velocity of the object, and the time the object spends in the air is frequently used in physics. 

Lucy and Kim determine the height of a building by dropping a brick from its roof. The initial velocity is 0m/s because lucy simply let go of the brick. Kim times the fall of the brick to be 3.5 seconds. What is the height of the building? 

Determine the amount of time the brick is in the air if Lucy throws the brick downward with an initial velocity of -5m/s. Round to the nearest hundreth of a second. 

A quadratic function has zeros at -3/2 and 6 the graph of the function passes through the point(1,-12.5). What is the equation of the function, in standard form.

the simplified form of the rational expression 10x^3+3x^2-x/ 25x^2-1

create a rational expression with a variable m that has non-permissible values of 3 and -1

On the reality TV show Last Man Standing, a package is thrown from a plane to the ocean below. The contestants must swim to the package to receive the “free pass” located inside the package. The path that the package follows can be modelled by the quadratic function d t 4 9. t t 10 1200 2 ^ h =- + + , where d represents the distance above the water, in metres, and t is the time, in seconds.

How long has the package been in the air when it hits the water?
