Simplify the trigonometric expression. sec θ cos θ
2 answers:
Lets imagine that we have:
Y = Sec(θ).Cos(θ)
As Sec(θ) = 1/Cos(θ)
Then we stay:
Y = 1/Cos(θ). Cos(θ)
Cos(θ) from up, will cut with Cos(θ) from down.
Then,
Y = 1
Answer:
y = 1.
Step-by-step explanation:
Given : y = sec θ cos θ.
To find : Simplify the trigonometric expression.
Solution : We have given that
y = sec θ cos θ.
By the trigonometric rule : sec θ = .
y = * cos θ.
y = .
y = 1.
Therefore, y = 1.

Answer:
6
Step-by-step explanation:
H = 10
L = 8
A = B = ?
By Pythogoras Theorem,
H^2 = L^2 + B^2
(10)^2 = (8)^2 + (B)^2
=> 100 = 64 + (B)^2
=> 100 - 64 = (B)^2
=> 36 = (B)^2
=> (B)^2 = 36
=> B = √36
=> B = 6
=> A = 6
Answer: The answer is C. The leading coefficient is -3 and the constants is 2.
explanation: I just took the test
B. This is because the value after the h is the x value. The 1400 on the other side of the equation is the y value.
