You can use the graphical solution method, you merely trace them on the ti 89 and Zoom to find the values of the functions.

I am horrible at maths need help asap


With algebra you are learning problem solving-that is the process of problem solving using rules and equations. The best way to learn it is to shut out all distraction and work at it. If there is something you don't understand you may have to go back to the beginning and learn all the principals and rules that you don't understand- Algebra can be a very hard subject but it can be concord with persistence.

Mdas problem solving


if you mean {7(2)2+[(3-2)-4x(3)]2} or 7(2)2+[(3-2)-4x(3)]2
{28+[(1)-12]2}
{28+[-12]2}
{28+-24}
=4
or if it was 4x not 4 times
{7(2)2+[(3-2)-4x(3)]2}
28+[(1)-12x]2
28+-24x
=-28x+28

The circumference of a circle is 47.1 feet. What is the diameter of the circle?


The circumference of a circle is C=2 * pi * r or C= pi * d.

What do we know? C=47.1 and pi.

What are we trying to calculate? d

Put what we know in the equation and solve for d.

47.1 = pi * d

To isolate d, we have to divide both sides by pi.

47.1
------ = d
pi

I get 14.99' or approximately 15' as the diameter.

Good luck,
Paul
