Answer:
7.9
Step-by-step explanation:
k^2 = 3.7^2+5.2^2-2(3.7)(5.2)\cos 124
k
2
=3.7
2
+5.2
2
−2(3.7)(5.2)cos124
Plug in values.
k^2 = 13.69+27.04-2(3.7)(5.2)(-0.559193)
k
2
=13.69+27.04−2(3.7)(5.2)(−0.559193)
Square and find cosine.
k^2 = 13.69+27.04+21.51774
k
2
=13.69+27.04+21.51774
Multiply.
k^2 = 62.24774
k
2
=62.24774
Add.
k=\sqrt{62.24774} \approx7.89 \approx7.9
k=
62.24774
≈7.89≈7.9
Answer:
4
Step-by-step explanation:
The given polynomial is :
p(x) = -2a⁴+8a³-9a
We need to find the degree of the polynomial.
Degree of the polynomial = degree is the value of the greatest exponent.
Here, the maximum value of the exponent is 4 in -2a⁴.
It means,
Degree of the polynomial = 4
30,220,617 is the number you just stated in standard form.
