a car travels along a straight road to the east for 150 meters in 4 seconds and west for 50 meters in one second
I'm pretty sure it's 22%
If it's not, then I'm sorry!!
I think it's (3) Calculate the nth term rule of the sequence
(I think
the answer to the equation is 8xy+36x+6y+9)
Answer:
1. Cosine
2. x = 49°
3. Sine
4. y = 41°
Step-by-step explanation:
1. The trig function that will be used to solve for x is cosine.
2. Determination of angle x
x° =..?
Adjacent = 13
Hypothenus = 20
Cos x = Adjacent /Hypothenus
Cos x = 13/20
Take the inverse of Cos
x = Cos¯¹ (13/20)
x = 49°
3. The trig function that will be used to solve for y is sine.
4. Determination of angle y.
y° =..?
Opposite = 13
Hypothenus = 20
Sine y = Opposite /Hypothenus
Sine y = 13/20
Take the inverse of Sine
y = Sine¯¹ (13/20)
y = 41°
The expressions that represent the slope of a tangent to the curve

<h3>How to find an expression for the slope at any point of a function</h3>
The slope at any point of the function can be found by definition of derivative following <em>algebraic</em> handling:




Thus, the expressions that represent the slope of a tangent to the curve
are
and
, respectively.
