Differentiate both sides with respect to <em>x</em>, using the chain rule for the sine term:


Solve for d<em>y</em>/d<em>x</em> :

Answer:
5/8 = 0.625 thus 0.65 is greater
Step-by-step explanation:
A rational number is an algebraic term expressed as a fraction. The fraction can also be in decimals but only if the decimal places are not repeating or not infinitely long. If they aren't, then these are called irrational numbers.
Let's try each of the choices:
A. The term 2/4 is a rational number. Now, when 0.3 or 3/10 is added to it, the sum would be 4/5 or 0.8. This is a rational number.
B. √7 is an irrational number because its exact value is 2.645751311.... Even if you add 0.3 to it, the answer would still be irrational
C. Obviously, this is an irrational number
D. The exact value of π is <span>3.14159...... If 0.3 is added to it, the answer would be 3.441592654. This is irrational.
Therefore, the answer is A.</span>
Answer:
13/20p
Step-by-step explanation:
Here, we want to write an expression from the given statement
We start from the product of 20 and p
Mathematically. that is 20 * p = 20p
Now to find the ratio, we simply place 12 over the product
We have this as;
13/20p
Answer:
2
Step-by-step explanation:
You should multiply by 2, to make it perfect square & it's square root is 64
