Answer:
(-1,0)
Step-by-step explanation:
It is decreasing when the "slope" of the function is negative. That only happens on the blue curve from x = -1 to x = 0. In interval notation, that's (-1,0)
A, they are vertical angels! they have the same measure!
Answer:
The ship S is at 10.05 km to coastguard P, and 12.70 km to coastguard Q.
Step-by-step explanation:
Let the distance of the ship to coastguard P be represented by x, and its distance to coastguard Q be represented by y.
But,
<P = 048°
<Q =
- 
= 0
Sum of angles in a triangle = 
<P + <Q + <S = 
048° + 0
+ <S = 
+ <S = 
<S =
- 
= 
<S = 
Applying the Sine rule,
=
= 
= 
= 
= 
⇒ y = 
= 12.703
y = 12.70 km
= 
= 
= 
⇒ x = 
= 10.0475
x = 10.05 km
Thus,
the ship S is at a distance of 10.05 km to coastguard P, and 12.70 km to coastguard Q.
Answer:
₹2835
Step-by-step explanation:
Working out discount of 10% of jeans at ₹1450:
10% of 1450 = 1450/10 = ₹145
the price would now be ₹1450 - ₹145 = ₹1305
Working out discount of 10% of a shirt at ₹850:
10% of 850 = 850/10 = ₹85
the price would now be ₹850 - ₹85 = ₹765
so the price of two shirts = ₹765 × 2 = ₹1530
the total the customer would have to pay:
₹1305 + ₹1530 = ₹2835
