Answer:
Step-by-step explanation:
Required to prove that:
Sin θ(Sec θ + Cosec θ)= tan θ+1
Steps:
Recall sec θ= 1/cos θ and cosec θ=1/sin θ
Substitution into the Left Hand Side gives:
Sin θ(Sec θ + Cosec θ)
= Sin θ(1/cos θ + 1/sinθ )
Expanding the Brackets
=sinθ/cos θ + sinθ/sinθ
=tanθ+1 which is the Right Hand Side as required.
Note that from trigonometry sinθ/cosθ = tan θ
Answer:
x=-1
Step-by-step explanation:
x^2+2x=16=0
Use the quadratic formula to find the solutions.
−b±√b2−4(ac)/
2a
Substitute the values
a=1, b=2, and c=−16 into the quadratic formula and solve for x
Answer:
The percent of change in 6 yards to 36 yards is 500% .
Step-by-step explanation:
Formula

Where
Change in value = Final value - initial value
As given
The percent of change in 6 yards to 36 yards.
Final value = 36 yards
initial value = 6 yards
Change in value = 36 - 6
= 30 yards
Put in the formula


Percentage = 500%
Therefore the percent of change in 6 yards to 36 yards is 500% .
