Answer: Our required formula becomes :
Step-by-step explanation:
Since we have given that
We need to write a formula for f(b) in terms of b So, it becomes
Hence, our required formula becomes :
You just need to find 100%-27%. That is 73%.
The measure of the angle is 20
Answer:
Step-by-step explanation:
The given polynomial equation is
We perform the synthetic division as shown in the attachment by dividing by x-2.
This gives a remainder of 0 and a quotient of
This means the polynomial equation becomes:
We factor the quadratic term by splitting the middle term;
Collect common factors again:
The solution is:
