we know that
if ∠UVW and ∠XYZ are complementary angles
then
∠UVW + ∠XYZ=90°
∠UVW=x-10
∠XYZ=4x-10
substitute the values
(x-10)°+(4x-10)°=90°
Solve for x
5x-20=90
5x=90+20
5x=110
x=22°
∠UVW=x-10=22-10=12°
∠XYZ=4x-10=4*22-10=78°
therefore
<u>the answer is</u>
x=22°
∠UVW=12°
∠XYZ=78°
1. "the graph has the same zeros" : so let a be the "triple" root of the cubic polynomial function.
2. So f(x)=

3. Don't forget that the expression might have a coefficient b as well, and still maintain the conditions:

4. Now, f(0)=-5 so




5. the function is

where a can be any real number except 0
Answer:
The circumference of the sphere is
or 
Step-by-step explanation:
step 1
Find the radius of the sphere
we know that the volume of the sphere is equal to

we have

substitute and solve for r

assume



step 2
Find the circumference
The circumference is equal to

we have

substitute


assume


I'm not sure exactly which type you are meaning since there are four types of expansions, but depending on which specific type here are your answers! :)
