The temperature at the base camp on Friday evening was -6°C
The temperature at a mountain base on Thursday = -2°C
On Friday morning, the temperature was 1 degree Celsius lower than what it was on Thursday, hence:
The temperature at a mountain base on Friday morning = -2°C - 1°C = -3°C
By Friday evening, the temperature was 3 degrees Celsius lower than what it was that morning.
The temperature at a mountain base on Friday evening = -3°C -3°C = -6°C
The temperature at the base camp on Friday evening was -6°C

Answer:
-6
Step-by-step explanation:
starts at -2
then drops -1
and lastly drops -3
which leaves you at -6 degrees Celsius

Step-by-step explanation:
Note that 1/√(2) is equal to √(2)/2:
1/√(2) = √(2)/2
So we're given that sin(x-20) = √(2)/2
The only place on the unit circle where sin() is equal to √(2)/2 is at π/4 and 3π/4.
That means the value inside the sine must be equal to π/4 and 3π/4:
since sin(π/4) = √(2)/2 and sin(π/4) = √(2)/2
then,
sin(π/4) = sin(x-20) and sin(π/4) = sin(x-20)
You set the inside of the parentheses equal to each other and solve for x.
You can also add a +2πk at the end since all sinusoidal graph repeats every 2π.

Answer: 0.16
Step-by-step explanation:
2/5=.4
.4^2=0.16
Answer:
0.16
Step-by-step explanation divide 2 with 5 you get 0.4. After that you have an exponent. You will take 0.4 to the 2nd power
Answer:
0.66667π radians
Step-by-step explanation:
1/3 = 0.33333
One-third of a complete angle in radians would be:
0.33333 · 2π ≈ 0.66667π radians
So, the answer is 0.66667π radians
B.) x= -8
C.) x= -6
D.) x= -1
The correct answer is C. -6
2 x -6 + 4 = -8
Hope this helps
10x+15y=
To factor the expression 10x+15y, we can factor out the greatest common factor (GCF) of 5 to get 5(2x+3y).
To factor the expression 10x+15y, we need to find the greatest common factor (GCF) of the two terms.
In this case, the GCF is 5, because both 10 and 15 are divisible by 5.
We can then factor out the GCF to get: 5(2x+3y).
