I believe your answer would be 240
but im not 100% sure
because a triangle equals up to 360 so 120-360= 240
Answer:
5, 15, 45 and 135
Step-by-step explanation:
Given the recursive function;
an = 3a(n-1)
If a1 = 5
a2 = 3a1
a2 = 3(5)
a2 = 15
For a3;
a3 = 3a2
a3 = 3(15)
a3 = 45
For a4;
a4 = 3a3
a4 = 3(45)
a4 = 135
Hence the first four terms are 5, 15, 45 and 135
Step-by-step explanation:
a (-infinite , -3) U (3 , infinite)
b + 5 , - 5
Answer:
5.28°
Step-by-step explanation:
Draw the triangle formed by the sledding run. The hypotenuse is 300. The height is 27.6. The angle of depression is opposite of the height.
Using sine:
sin θ = 27.6 / 300
sin θ = 0.092
θ = 5.28°
Okay, the f^-1 means we need to invert the original function. So switch x's and y's and solve for y.
y = 3x - 27/14
x = 3y - 27/14
-3y = -x - 27/14
y = 1/3x + 9/14
Then plug in 241
y = 80 1/3 + 9/14
y = 80 41/42
Now you have to plug it back into the original function.
So:
y = 3(80 41/42) - 27/14
y = <span>3401/42 - 27/14
y = </span>79.0476190476 or 79<span> and 1/21</span>
