Step-by-step explanation:

1. 10s2 + 10s2 - 13st = 20s2-13st

2. 13st + - 2st - t2 = 11st - t2

3. x2+ x2 + x3= 2x2 + x3

4. 6 x - 6 x + 2=X+2

5. 24x - 3s - 4t=24x - 3s - 4t

6. 86 + 86x - 1=85+86x

7. 4x + 3x - 2 =7x - 2

8. 7s - 4s + 3s =6s

9. 12 +11x - 10 x = 12+x

10. 12x + 24 x - 3 x - 4 =33x -4

11. 16t + 8t - 12t =12t

12. 17g + 19g - 2g +g =35g

13. 16 + 16 -16 + 16x =16+16x

14. 4s - 3s + 3s =4s

15. 12t - 11t + t =2t

consider the polynomial 6x^4+24x^3-72x^2. what is the greatest common factor of the terms of the polynomial
mash [69]

First, look at the coefficients, 6, 24, -72. 6 is a factor of 6, 24, and -72. Since one of the coefficients is in fact 6, then 6 is the GCF of the coefficinets.

Now look at the variables. You have x^4, x^3, and x^2. Remember what the exponents mean. They mean a multiplication of several factors of x.

x^4, x^3, x^2 mean xxxx, xxx, xx

xxxx, xxx, xx have 2 factors of x in common, so the greatest common factor of the variables is xx which is the same as x^2.

When you put together the common factor of the coefficients and the common factor of the variable parts, you get GCF = 6x^2.

Please help me with the below question.
o-na [289]

Given that

\vec r(t) = \left\langle 4t e^{-t}, 8 \arctan(t), 8 e^t \right\rangle

we first differentiate with respect to t to get the tangent vector, \vec T(t) :

\vec T(t) = \dfrac{d\vec r}{dt} = \left\langle (4-4t) e^{-t}, \dfrac8{1+t^2}, 8e^t \right\rangle

At t = 0, the tangent vector is

\vec T(0) = \left\langle 4, 8, 8 \right\rangle

To get the <em>unit</em> tangent vector, multiply this by 1/(norm of tangent vector) :

\|\vec T(0)\| = \sqrt{4^2 + 8^2 + 8^2} = \sqrt{144} = 12

Then the unit tangent vector is

\dfrac{\vec T(0)}{\|\vec T(0)\|} = \left\langle \dfrac4{12}, \dfrac8{12}, \dfrac8{12}\right\rangle = \boxed{\left\langle\dfrac13, \dfrac23, \dfrac23\right\rangle}

Which statement about the equation 3/4y = 5/x is true?
VARVARA [1.3K]

Answer:

the answer would be no solution

Step-by-step explanation:

because, Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation

  3/4y-(5/x)=0

and from there you may not do anything else.

An experiment for a chemical reaction involves mixing 1 teaspoon of yeast with 1/4 cup of hydrogen peroxide. Delray wants to do
arlik [135]

Answer:

1/8 cups

Step-by-step explanation:

For every quarter of a cup of peroxide, there is a teaspoon of yeast. there are six quarter cups in one and a half cups, so there is 6 tsp of yeast. Divide 6 by 48 (to bring it into cups) and that leaves you with 0.125 cups, or 1/8 cups. Hope this helps!
