Answer:
A
Step-by-step explanation:
x / 5 = 1
multiply each side by 5
(x / 5)5 = (1)5
x = 5
Answer:
2,-12
Step-by-step explanation:
The given equation is ,
We know that modulus only gives positive value , Therefore on squaring both sides we have ,
Answer:
v is the wave speed in metres per second, m/s. f is the frequency in hertz, Hz. λ (lambda) is the wavelength in metres
The value of the cos P + cos Q is 7/5 if sin Q = 4/5 after applying the identities of trigonometric.
<h3>What is trigonometry?</h3>
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We know that:
P + Q are complementary, which means that
P+Q = 90°
Then R is a right angle, i.e. it measures 90°.
sin(90-x) = cos (x)
cos(90-x) = sin (x)
Then sinQ = 4/5
cos(90-Q) = cosP = 4/5
Now sin²(P) + cos²(P) = 1
sin²(P) = 1 - cos²(P)
sin²(P) = 1 -[4/5]² =9/25
sin(P) = 3/5
cos(Q) = sin(P) = 3/5
cos(P) + cos(Q) = 4/5 + 3/5 = 7/5
Thus, the value of the cos P + cos Q is 7/5 if sin Q = 4/5 after applying the identities of trigonometric.
