B.)sin -1 y/100
c.)tan -1 y/100
D.)cos -1 100/y
E.)sin -1 100/y
Answer: Hello there! The correct answer is A.
If the bird flies 100 yards with an angle of elevation of x from the ground, then you could think this as a tringle rectangle, where the hypotenuse is 100 yards, the opposite cathetus is sin(x)*100 and this represents the height at which the bird dropped the fish, not really useful here.
The adjacent cathetus us 100*cos(x), in this case, you are calculating the displacement adjacent to them (because the angle is with respect to the ground) and knowing that the fish lands in a translated y yards horizontally we could write: y = cos(x)*100
now we want to isolate x:
y/100 = cos(x)
arcos(y/100) = arcos(cos(x)) = x
x = arcos(y/100) (or cos-1(y/100) like in the option A)
then, knowing the value of y, we could obtain the angle x with that equation.
1. −4x+12y−5
2. −x+9y−5
3. −x−25y+5
4. 25x−19y+3
The expression that is equivalent to the given expression is -x+9y−5. The correct option is 2. −x+9y−5
From the question,
We are to determine the expression which is equivalent to the given expression.
First, we will simplify the given expression
The given expression is (12x−5y−1)+(17y−4−13x−3y)
The expression can be simplified as shown below
(12x−5y−1)+(17y−4−13x−3y)
12x−5y−1+17y−4−13x−3y
Collect like terms
12x−13x+17y−5y−3y−4−1
This becomes
-x+9y−5
The simplified expression is -x+9y−5
Hence, the expression that is equivalent to the given expression is -x+9y−5. The correct option is 2. −x+9y−5

B)write an equation of the line tangent to the graph of f at the point where x=1
C) find the x coordinate of each point at which the line tangent to the graph of f is parallel to the line y=-2x+4
A convenient way to find the zeros of is by factoring.
a) The equation,
can be rewritten as,
We can think of this equation as a quadratic equation in , with .
Observe that .
We find two factors of 2 that adds up to . These are, .
Now let us split the middle term. to obtain;
We can factor to get,
We factor further to obtain;
Hence the zeroes of are;
b) To find the line tangent, we must first, find the slope using differentiation. That is,
At ,
Also, we need to determine the value at . That is;
Now we can use the slope and the point to write ythe equation of the line tangent.
c)
If the line tangent is parallel to the line , then
Since parallel lines have the same slope.
Hence the x-coordinates are,
