Answer:
Option B
Step-by-step explanation:
By using geometric mean theorem in the given right angle triangle RST,



ST² = 10.2 × 14.3
ST = 
ST = 12.077
ST ≈ 12.1
Therefore, Option B will be the correct option.
Answer: y= -9 .
Step-by-step explanation:
If the line has no slope, then no matter what x is, y never changes.
sin45=5/x so x is 5/(sin45)
y is 5/(tan45)
question 5 then you just go x= (9sqrt(2)/2)/sin45
i don’t have a calculator rn so just plug it into it
Nooo im pretty sure it cannot
If r is the radius of a sphere its surface area = 4(pi)r^2.
If the radius is doubled then its surface area = 4(pi)(2r)^2 = 4*4(pi)r^2.
So the surface area becomes 4-fold or the increase in surface area is 300%.
