Answer:
The question is x^2 = 20, right? then
second option is the answer
5x-11=-13
add 11 on both sides
5x=-2
divide by five on both sides
-0.4
x=-0.4
I hope that's what you were asking

Step-by-step explanation:
According to the quotient rule of differentiation, if
then its derivative is given by

We can see that




Plugging the above expressions into Eqn(1), we find that the derivative is


Answer:
785.4 units³ (nearest tenth)
Step-by-step explanation:
volume of a cylinder =
r²h
where r is the radius and h is the height
diameter of a circle = 2r
where r is the radius
Therefore, 10 = 2r ⇒ r = 5
Therefore, volume =
x 5² x 10 = 250
= 785.4 units³ (nearest tenth)
Answer:
308.4miles
Step-by-step explanation:
Given that radius of earth= 4000miles
Change in latitude = 39° 8' 46" - 34° 43'41"
= 4° 25' 5"
= 4+25/60+5/3600
4+0.4166+0.00138
θ = 4.417°
Converting to radian = 4.417°×π÷180
= 4.417×0.0174
= 0.07710
Distance between the cities = rθ
S = 4000×0.07710
S= 308.4miles
