I Believe the mean would would 60 degrees Fahrenheit
Answer:
y maximum is at 1 for both the points (4,1) and (-4,1)
Step-by-step explanation:
Answer: 15
Step-by-step explanation: so you take the 5 ( or 3 it doesn’t matter In multiplication) and just add the 5 3 times. So 5+5+5 which is 15
Part 1) we know that
Volume of rectangular prism=L*W*H-------> 3*6*4-----> 72 units ³
and
Volume of rectangular prism=Area of the base*H
Area of the base B=L*W------> 3*6----> 18 units²
so
Volume of rectangular prism=18*4-----> 72 units³
the answer Part 1) is the option
C) V=Bh
Part 2) we know that
Volume of rectangular prism=L*W*H-------> 5*2*3-----> 30 units ³
and
Volume of rectangular prism=Area of the base*H
Area of the base B=L*W------> 5*2----> 10 units²
so
Volume of rectangular prism=10*3-----> 30 units³
the answer Part 2) is the option
<span>C) V=Bh
Part 3) </span>we know that
Volume of rectangular prism=B*H
B=area of the base--------> 5*3-----> 15 units ²
H=3 units
Volume of rectangular prism=15*3-----> 45 units³
and
Volume of rectangular prism=L*W*H
Volume of rectangular prism=5*3*3-----> 45 units³
the answer Part 3) is the option
<span>C) V=LWH
Part 4) </span>Part 3) we know that
Volume of rectangular prism=B*H
B=area of the base--------> 5*5-----> 25 units ²
H=7 units
Volume of rectangular prism=25*7-----> 175 units³
and
Volume of rectangular prism=L*W*H
Volume of rectangular prism=5*5*7-----> 175 units³
the answer Part 4) is the option
C) V=LWH
Fundamentally you can get there using the identity
... sin(a)² + cos(a)² = 1
... 1/cosec(a)² + 1/k² = 1 . . . . . substituting for sec(a) and sin(a)
... 1/cosec(a)² = 1 - 1/k² = (k² -1)/k² . . . . subtract 1/k²
... cosec(a)² = k²/(k² -1) . . . . . Multiply by cosec(a)²k²/(k²-1)
... cosec(a) = k/√(k²-1) . . . . . .take the square root

You can get there slightly faster using the identities tan²=sec²-1; csc=sec/tan.
