Answer: c I think if I’m wrong report my comment
A minus x plus b equals c
Y= 5.91 yup that’s the answer
R = 8 tan(x) sec(x)
In order to solve this, we are going to use the following:
r = sqrt(x^2 + y^2) //but in this case, we don't need this.
tan(x) = Y / X
X = r cos(x)
Y = r sin(x)
<span>(r cos x)^2 = 8(r sin x)</span>
x^2 = 8y
Answer:
70.56
Step-by-step explanation:
The variance is the standard deviation squared.
σ² = (8.4)² = 70.56
