What is Pythagorus Theorem ? Find the length of BC if given a right angle triangle ABC where AB is 8cm and the length of the hypotenuse AC is 10cm ?

Pythagorus Theorem states that the side of a 'Right Angled Triangle' can be found by using the formulae c²= a²+ b², where c is considered as hypotenuse. In our case the...

Solve: 5x - 2 > 3x + 11

5x - 2 > 3x + 11
5x - 3x > 11 + 2
2x > 13
x > 13/2
x > 6.5

Q = P/ R (4 – t) Calculate the value of Q when P = 36, R = 3 and t = –2

First list what the question gives you.

p=36 r=3 t=-2

Sub in the values that you know into the equation.

Q= 36/ 3(4--2)

Q= 36/18

Q=2

Differentiate: 6x^2 + 5x +7 =y

6x^2 + 5x +7 =y

dy/dx = 12x + 5

To solve for a point of inflection:

dy/dx = 12x + 5 = 0

x=-5/12

y=143/24

Given a circle with the equation y^2 + x^2 = 10, with a tangent that intersects at point P, where x=1, find the coordinates for the point at which the tangent meets the x axis (Q).

As the tangent meets the circle at P, when x =1, we can assume that the y value will be the same for this value of x. therefore we substitute x=1 into the equation of the cirlce. Rearranging the equation ...
