A wire is to be attached to support a telephone pole. Because of surrounding buildings. sidewalks, and roadways, the wire must b
e anchored exactly 15 feet from the base of the pole. Telephone company workers have only 30 feet of cable, and 2 feet of that must be used to attach the cable to the pole and to the stake on the ground. How high from the base of the pole can the wire be attached?
Step-by-step explanation: the length of the cable and he distance on the ground and the height all forms a right angles triangle. With the length if the cable being the hypotenuse . since 2ft of cabkes are remobed,28 ft woukd be left, you can therefore apply the Pythagoras theorem and square of 28 - the square of 15 gives the square of the height at which it should be hung.
x^2+7x+12 can be done by factoring as a process of ax^2+bx+c, whereas a is equal to 1.
First, we need to know 2 numbers that multiply to 12 and add to 7. In that case, that would be 6 and 2. And then finally write the variable x in the first parts of the parentheses, that would be: (x+6)(x+2).
Each square on the grid represent 1m2 what is the aproximate area of the grassy field A about 5 mt to 15m2 B 20m2 to 30m2 C 35m2 to 45m2 please help me
