Write 34/7 as a mixed number in simplest form

Mathematics

Answer:

4 6/7

Step-by-step explanation:

34/7

We finds out how many 7s are in 34

5 * 7 is 35, so it must be 4.

when 34 is divided by 7, the answer would be 4 and 6 remainders.

put the remainders back into the nominator part of the fraction.

so it's 4 6/7

The answer is 4 6/7

Explanation:

34 goes into 7, 4 times so that would be four wholes and the remainder would go over seven
So 34-28 = 6

Therefore, you would get 4 6/7.

The position vector for a particle moving on a helix is
topjm [15]

Answer:

a) 25.15

b)

   x = 1

   y = t

   z = (4pi)^2 + t *(8pi) = 4pi(4pi + 2t)

c) (x,y) = (1, -2pi)

Step-by-step explanation:

a)

First lets calculate the velocity, that is, the derivative of c(t) with respect to t:

v(t) = (-sin(t), cos(t), 2t)

The velocity at t0=4pi is:

v(4pi) = (0, 1, 8pi)

And the speed will be:

s(4pi) = √(0^2+1^2+ (8pi)^2) = 25.15

b)

The tangent line to c(t) at t0 = 4pi has the parametric form:

(x,y,z) = c(4pi) + t*v(4pi)

Since

 c(4pi) = (1, 0, (4pi)^2)

The tangent curve has the following components:

x = 1

y = t

z = (4pi)^2 + t *(8pi) = 4pi(4pi + 2t)

c)

The intersection with the xy plane will occurr when z = 0

This happens at:

  t1 = -2pi

Therefore, the intersection will occur at:

(x,y) = (1, -2pi)

Can someone help me with number 8 please? Thank you.

Answer: -4 \le x \le 5
Note: to write the domain in interval notation, you'd write [-4,5]
if you need the domain in set-builder notation, then you'd write \left\{x|x\in\mathbb{R}, \ -4\le x\le 5\right\}

------------------------------------------------------------------------------

Explanation:

The domain is the set of possible x input values. Look at the left most point (-4,-1). The x coordinate here is x = -4. This is the smallest x value allowed. The largest x value allowed is x = 5 for similar reasons, but on the other side of the graph.

So that's how I got -4 \le x \le 5 (x is between -4 and 5; inclusive of both endpoints)

Writing [-4,5] for interval notation tells us that we have an interval from -4 to 5 and we include both endpoints. The square brackets mean "include endpoint"

Writing \left\{x|x\in\mathbb{R}, \ -4\le x\le 5\right\} is the set-builder notation way of expressing the domain. The x\in\mathbb{R} portion means "x is a real number"

Simplify <br> 2/3(30d-15)<br> Can someone please explain distributive property with fractions?
Oksana_A [137]

Answer:

You do 2/3 times 30d minus 2/3 times 15. That will give you 20d - 10

Step-by-step explanation:

(2/3x30d) - (2/3x15) = 20d - 10
