What is the derivative of the 5th root of t^3?
mariarad [96]

\bf y=t^{\frac{3}{5}}\implies \cfrac{dy}{dt}=\stackrel{\textit{using the power rule}}{\cfrac{3}{5}t^{\frac{3}{5}-1}}\implies \cfrac{dy}{dt}=\cfrac{3}{5}t^{-\frac{2}{5}}
\\\\\\
\cfrac{dy}{dt}=\cfrac{3}{5t^{\frac{2}{5}}}\implies \cfrac{dy}{dt}=\cfrac{3}{5\sqrt[5]{t^2}}

Randolph is creating parallelogram WXYZ so that WX has an equation of y = 1 over 4x − 6. Segment YZ must pass through the point
Nostrana [21]

Answer:

y - 5 = 1/4 (x - (-1))

Step-by-step explanation:

Since we have a parallelogram, then WX and YZ must be parallel

mathematically, the general equation of a straight line is;

y = mx + b

where m is the slope and b is the y-intercept

if two lines are parallel, the value of their slopes is same

for the first line, we have;

y = 1/4x - 6

The slope of the first line is 1/4

this is the slope of the second line too

By using;

y-y1 = m(x-x1)

where (x1,y1) is the point on the line

we have;

y - 5 = 1/4 (x - (-1))

In 2010, Haiti was hit by a devastating earthquake, which registered at 7. 0 on the Richter scale. The largest recorded earthqua
ddd [48]

Answer:

I think it's 2.5

Step-by-step explanation:

Since the Chilean earthquake was 9.5 and Haiti was 7.0 the just subtract from the 9.5 to get the greater. Obviously a 9.5 on the Richter scale is going to do way more damage either way. I apologize if I'm wrong, bit I think it's 2.5 (If not that selection choose 2) Have a great day loves!! <3

Write 560% as a decimal and as a mixed number
vekshin1
560% as a decimal = 5.6
(move the decimal points 2 spaces to the left.)

560% as a mixed number = 5 3/5
(divide 560 by 100; 100 goes into 560 5 times so 5 will be your whole number and since you have 60 left you divide 60 by 100; 60/100 can be reduced to 3/5 if you divide the numerator and the denominator by 20)

hope this helps :)
