50 thatat is the rate of change for the relationship represented in the graph?
Do u have a picture of the assignment?
Multiply the dust particle mass by 5 billion..
On a calculator use the "EE" button is shorthand for: x10^ whatever power you want.
5x10^9 x 7.53x106-10 = 3.765
2tan(x)
i. take the 2 out
ii. derivative of acos is -sin
iii. derivative of In is -ve inverse
so we have 2 times sin(x)/cos(x) hence 2tan(x)
Answer:
Factorising the equation into brackets can help you identify where the x-intercepts are (where the function cuts the x-axis)
Step-by-step explanation:
When you factorise the equation it would look something like this:
(x + a)(x + b) = 0
This also means:
x + a = 0 and x + b = 0
x = -a and x = -b
Example:
Find where the function y = 2x² + 8x + 6 cuts the x-axis
Factorise the 2 out (highest common factor)
x² + 4x + 3 = 0
(x + 1)(x + 3) = 0
x = -1 or -3
