Answer:The roots of any quadratic equation is given by: x = [-b +/- sqrt(-b^2 - 4ac)]/2a. Write down the quadratic in the form of ax^2 + bx + c = 0. If the equation is in the form y = ax^2 + bx +c, simply replace the y with 0. This is done because the roots of the equation are the values where the y axis is equal to 0.
Step-by-step explanation:
That question isn't nearly as hard as they want it to be. The "a" in the sin function is the altitude of the function...how high it goes up and how low it goes down. The negative in front of the 7 just means that it starts going down before it goes up (a classic sine wave goes up and then down; the negative just reverses that). From the wave's midpoint on the y axis, which is 11 (hence, the +11 in the equation), the wave goes up 7 (to a y value of 18) and then goes down 7 (to a y value of 4). Because it goes up 7 and then down 7, the diameter of the pinwheel is 14. The sin wave mimics the round and round motion of the pinwheel. You could have been able to tell that it was 14 just by looking at what the altitude was. The altitude is always the number the wave goes up and down from its midpoint. 7 up and 7 down makes 14 altogether.
Answer:
X° + 2x° + 45° = 180°
X = 45°, 2x = 90°
Step-by-step explanation:
Since the angles in a triangle sums up to 180
And the angles in this particular triangle is measured as 2x° + x° + 45° = 180
With this equation, we can find the value of x and 2x
2x + x + 45 = 180
3x + 45 = 180
3x = 180 - 45
3x = 135
Now divide both sides by 3
3x/3 = 135/3
X = 45
Therefore, the angles of that triangle are x° = 45, 2x°= 45 × 2 = 90° and the third angle which was given to us as 45°
