Answer:
Alright well solve for z by simplifying by both sides of the equation, then isolating the variable
Exact form: z = 2/5
Decimal form: o.4 Hope this helps :)
Step-by-step explanation:
The radius of the new sphere is 9
The new SA should be 1017.36 in
New volume should be 3052.08in^3
Answer:
its already in its simplest form.
We are given

Firstly, we will simplify left side
and we will check whether it is equal to right side
Left side:
Let's assume y left side expression

now, we can take cos on both sides

we can simplify it

Right side:
Let's assume y left side expression

Multiply both sides by -1

now, we can take cos on both sides

we can simplify it


we can see that
both sides cos(y) value is different
so, this is FALSE.........Answer
