Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
sin²x + cos²x = 1 ⇒ sin²x = 1 - cos²x
Given
sin²x + 7cosx + 17
=1 - cos²x + 7cosx + 17
= - cos²x + 7cosx + 18 ← factor out - 1 from each term
= - (cos²x - 7cosx - 18)
Consider the factors of the constant term (- 18) which sum to give the coefficient of the cosx term (- 7)
The factors are - 9 and + 2, thus
= - (cosx - 9)(cosx + 2) ← in factored form

First the question asks you how many problems Cesar did per day in a 5 day school week. We know that he did 100 problems in that 5 day week, so you should divide 100 by 5 to get 20. Now we know that Cesar does 20 problems per day. Now the question want you to find how many problems he would do if this rate keeps up in three 5 day weeks. We know that he does 100 problems in a five day week, so multiply 100 by 3 to get 300. So Cesar does 300 percent problems in three weeks and 20 problems in one day.
Answer:
They have the same slope of 2 and are, therefore, parallel.
Step-by-step explanation:
Given: Equation of FG is 
and equation of EH is 
To find: Relation between segments FG and EH
Solution:
Slope of a line describes its direction and the steepness.
Two lines are said to be parallel if their slopes are equal.
Differentiate with respect to x
where 
denotes the slope of the line FG
Differentiate with respect to x
where 
denotes slope of line EH
As 
, lines are parallel
