Step-by-step explanation:
1. cos x sec x
Secant is the inverse of cosine.
= cos x (1 / cos x)
= 1
2. sin x csc x
Cosecant is the inverse of sine.
= sin x (1 / sin x)
= 1
Graphed it should look like this.
Answer:
-11°C
Step-by-step explanation:
Original Temp = -2°C
Temp Drop (i.e temperature is reduced by) = 9°C
Final Temperature,
= Original Temp - Temp Drop
= -2°C - 9°C
= -11°C (Ans)
Answer:
x = 5, 15 y = 30
Step-by-step explanation:
y=3x is the rule, thus you can use it to find all values.
15 = 3x Divide 15 by 3 in order to isolate the variable
5 = x
y = 3(10) Multiply 3 by 10 in order to find y
y = 30
45 = 3x Divide 45 by 3 in order to isolate the variable
15 = x
OK...... your answer would be
- 10y^2 - 26y + 1/y
