ordinarily, partial derivatives are used for functions of more than one independent variable because if you think of the derivative as a slope, then for functions of more than one variable, it is easiest to work with slopes in the direction of each of the coordinate axes (just as it is in the (simplest) case of a function of one variable, like y=f(x)). the partial derivatives just give you the slopes in the direction of each of the axes. however, there are ways to combine these partial derivatives to give a single entity (vector, matrix, etc.) that represents the derivative of your multivariable function.

with x-y axes centered at the school, x-axis running east & west and y-axis running north & south, a right triangle is formed having legs "east-west distance" (x) and "north-south distance" (y) and "distance from school (400)" (hypotenuse). the road from school makes a 50 degree angle with the west direction of the x-axis, so x/400=cos(50) or x=400*cos(50) or x=257.1 (approx).

according to Websters:

"1a. a number usually expressed in the form 'a/b' where 'a' is any real number and 'b' is any real number different from zero equal to the quotient of 'a' divided by 'b'; the ratio between any two numbers." "1b. a ratio of algebraic quantities similarly expressed."

Aritmetic series:
Sn= n/2* (2a+(n-1)b)
disini (here)
1+2+3+...+100
a= 1 suku Pertama (firts Unit)
b=1 selisih ( diffrerent near units. example : b= 2-1 = 1 b=3-2=1 )
n=100 banyaknya suku ( amount of units)

Sn= n/2 (2a+(n-1)b)
S 100= 100/2 (2*1+(100-1)*1)
S100= 50 (2+99*1)
S100= 50 (2+99)
S100= 50 * 101
S100= 50 * 101
S100= 5050

simple formula for this series
Sn= n/2 *(2+(n-1)1)
Sn= n/2 *(2+n-1)
Sn= n/2 *(n+1) or
Sn= 1/2*n* (n+1)
ok

prob #2

mean = sum/N or sum=N*mean
consider the two groups of students applying the latter formula:
group1: 8.5 = sum/15 or sum=8.5*15=127.5
group2: sum = 20*mean (and this mean is the unknown value that we are looking for)

the mean for the entire class is 8.1 and that is gotten by adding up all the values (sum of everybodies' scores) and dividng by 60:

8.1 = (sum group1 + sum group2)/35 or (127.5+20*mean)/35=8.1

using algebra, solve this equation for "mean"

mean = [(8.1*35)-127.5]/20 = 7.8

will solve in 2 (separate) replies.

prob. #1:

mean (original) = mo = (w1+w2+...+w59+w60)/60

mean (adjusted) = ma = [(w1+3)+(w2+3)+...(w20+3)+w21+...+w60]/60

using algebra to rearrange terms and using the properties of fractions

ma = [(w1+w2+...w59+w60)+(3+3+...+3)]/60 = [(w1+w2+...w59+w60)/60]+[(20*3)/60]

the first term is the original mean and has value 27g, the second term is a constant with value 1g

so the answer is 28g

x^(4/6)=4
(x^(4/6))^6/4=4^6/4
X = (2^2)^6/4
X = 2^12/4

use inverse functions to solve for x: starting with x^(4/6)=4

1. raise both sides to the 6th power: x^4 = 4^6 or x^4 = 4096

2. raise both sides to the (1/4)th power: x^1 = 4096^(1/4) or x = 8

Guest:
I believe the answer is about 10m/s
F=ma
m=55kg
F=75N
a=F/m=75/55=(about) 1.36m/s^2
Finally, Vf=Vi+at
t=7.5s
Vf=(0m/s)+(~1.36m/s^2)(7.5s)
=(1.36)x(7.5)
=(10.227)
(significant digits)
Vf=10m/s
Hope this helps

Of course... I believe this is only true if we neglect the Force of friction.
