Answer:
To find x we use sine
Sine ∅ = opposite/ hypotenuse
x is the opposite
The hypotenuse is 15cm
sin 35° = x / 15
x = 15 sin 35°
x = 8.60
x = 9cm to the nearest tenth
Hope this helps you
Answer:
Step-by-step explanation:
2x = 3*6
2x/2 = 18/2
x = 9
Answer:
When f(n) = 4n and g(n) = n² + 2n, f(g(-6)) = 96.
Step-by-step explanation:
To evaluate f(g(-6)), first find g(-6).
g(n) = n² + 2n
Substitute value.
g(-6) = (-6)² + 2(-6)
Square -6. Remember that (-x)² = x²
g(-6) = 36 + 2(-6)
Multiply 2 and -6.
g(-6) = 36 - 12
Subtract 12 from 36.
g(-6) = 24.
Now knowing this, substitute that value into f(n).
f(g(-6)) = f(24)
f(n) = 4n
Substitute value.
f(24) = 4(24)
Multiply 4 and 24.
f(24) = 96.
