Hello,
if tan x=√3/3 then x=30°+k*180° k: integer
First add 5 to right side

Next , to cancel the 7, you need to multiply by 7 on both sides
Answer:
its positive
Step-by-step explanation:
because the line going upward
Answer: {(-5, 6), (-3, 13), (-14, 30)} is a function
{(12, 12), (12, 13), (12, 14)} and {(1, 3), (4, 5), (4, 9), (6, 19)} are not a function
First, we must solve for the radius of the sphere:
V=



r=(3

)

r=(3*

)

r≈5.99
Second, we must solve for surface area:
A=4


A=4*

*

A≈450.88
