Answer:
a)
b)
c)
d)
Step-by-step explanation:
We will use the following trigonometric identities
.
Recall that given a right triangle, the sin(theta) is defined by opposite side/hypotenuse. Since we know that the angle is in quadrant 2, we know that x should be a negative number. We will use pythagoras theorem to find out the value of x. We have that
which implies that . Recall that cos(theta) is defined by adjacent side/hypotenuse. So, we know that the hypotenuse is 7, then
b)Recall that , then using the identity from above, we have that
c) Recall that . Then,
d) Recall that and . Then

Step-by-step explanation:
since maxima is a point in which a function within a range gives maximum value. And its value is called maximum value of the function over an interval.
Answer:
4.8 sheets of paper
Step-by-step explanation:
You just need to divide 120 by 25 students. The reason for that is because you need to find out how much *each* student has.
120/25 = 4.8
As a fraction
Mixed = 4 4/5
Improper = 24/5
The unit rate is any of these answers! Don't forget your units :)
Answer:
7 miles
Step-by-step explanation:
As, we will take unit rate as "x"
So, for one day = x distance
For 5 days = 5(x)
For 5 days she covered 35 miles
So therefore,
5(x) = 35 miles
X= 35/5
X=7 miles
For a day= 7 miles are covered
