If x=at^3 and y=bt^2 then find dy/dx
Answers
dy/dt = 2bt
dx/dt = 3at^2
therefore dy/dx = 2bt/3at^2
dy/dx = 2b/3at

(0,0), (2,6), (4,12), (6,18) and (8,24) [If you did not make a mistake by typing a point (8,27)], THEN
it is a direct proportional relationship in question, defined by formula:
y = k*x
where k is coefficient of this proportion, and x and y are coordinates of points respectively.
So, if you check for EACH point:
0 = k*0,
6 = k*2,
12=k*4,
18=k*6,
24=k*8,
for each of these equations, it is obtained for k to has value of 3.
And the rule is for a proportion, that has to have SAME k value for each of its points on a line.
So the answer is TRUE.
But if you did not make a mistake by typing point (8,27), then k value for its equation
27=k*8, will not be 3 as for the rest of the points.
And then, the answer would be FALSE, it is NOT a proportional relationship.

the answer is false, i took the test

Step-by-step explanation:
The easiest way to do this is by using synthetic division (I really hope you know what I'm talking about!)
If the factor is x + 2 = 0, then the solution or the root is x = -2. We will put -2 outside the "box" and the coefficients from the terms of the polynomial inside the "box":
-2| 1 0 0 8
Bring down the first number and multiply it by the -2. Put the product up under the first 0 and add:
-2| 1 0 0 8
-2
1 -2
Now multiply the -2 by the -2, put the product up under the next 0 and add:
-2| 1 0 0 8
-2 4
1 -2 4
Now multiply the 4 by the -2, put the product up under the 8 and add:
-2| 1 0 0 8
-2 4 -8
1 -2 4 0
Those bold numbers are the coefficients to the quotient, which is another polynomial, but is one degree less than the one you started with:
x² - 2x + 4 = 0
Since there is no remainder, then x = -2 is a zero of x³ + 8, and (x + 2) is a factor.

Step-by-step explanation:
sin(x) + tan(x) =sin(X) + sin(x)/cos(x)
=sinx(1+1/cosx)
=Sinx(1+secx)
=1+secx/cosecx. (Since sinx=1/cosecx)
Hence LHS=RHS proved

Answer:
Option B is correct that is the expression is equivalent, but it is not completely factored.
Step-by-step explanation:
We have given an expression
when we take the common factor out which is 3 from the expression we will get
This expression is equivalent but is not completely factored because the term
Hence, Option B is correct.
Option C and D are discarded because given factor is equivalent
Option A is discarded because expression is not completely factored.

Answer:
D
Step-by-step explanation:
if y=2 then x=6, 2x3=6 ...if you multiple y with 3..you will get the answer of x
in that equation above..it will get x=3y...but there is no answer for it..so, you can convert it to, y=1/3x
Answer:
the answer is D
