Step-by-step explanation: Took the test it is right
Answer:
-10
Step-by-step explanation:
Answer:
D. 0.34
Step-by-step explanation:
0.24²+0.31²=x² then you find the square root
4x^2-3x+4y^2+4z^2=0
here we shall proceed as follows:
x=ρcosθsinφ
y=ρsinθsinφ
z=ρcosφ
thus
4x^2-3x+4y^2+4z^2=
4(ρcosθsinφ)^2-3(ρcosθsinφ)+4(ρsinθsinφ)^2+4(ρcosφ)
but
ρ=1/4cosθsinφ
hence we shall have:
4x^2-3x+4y^2+4z^2
=1/4cosθsinθ(cosθ(4-3sinφ))+4sin^2(φ)
X = 6 / tan(67)
x = 2.546
rounded to nearest tenth x = 2.5
