Give a vector parametric equation for the line through the point (−2,−4,0) that is parallel to the line ⟨−2−3t,1−4t,−5t⟩:

Answers

The tangent vector for the given line is

T(t) = d/dt ⟨-2 - 3t, 1 - 4t, -5t⟩ = ⟨-3, -4, -5⟩

On its own, this vector points to a single point in space, (-3, -4, -5).

Multiply this vector by some scalar t to get a whole set of vectors, essentially stretching or contracting the vector ⟨-3, -4, -5⟩. This set is a line through the origin.

Now translate this set of vectors by adding to it the vector ⟨-2, -4, 0⟩, which correspond to the given point.

Then the equation for this new line is simply

L(t) = ⟨-3, -4, -5⟩t + ⟨-2, -4, 0⟩ = ⟨-2 - 3t, -4 - 4t, -5t

The vector parametric equation for the line through the point is [tex]r = (-2, \ -4, \ 0) +(-3, \ -4, \ -5)t\\\\[/tex].

Give a vector parametric equation for the line through the point (−2,−4,0) that is parallel to the line ⟨−2−3t,1−4t,−5t⟩.

What is a parametric equation vector?

Parametric equations of the line segment are defined by its endpoints.

To find the vector equation of the line segment, we’ll convert its endpoints to their vector equivalents.

Two lines are parallel if they have the same direction, and in the parametric form, the direction of a line is always the vector of constants that multiply t (or the parameter).

The vector equation of a line is given by:

[tex]\rm v = r_0+tv[/tex]

Where v is the direction vector and [tex]\rm r_0[/tex] is a point of the line.

The tangent vector for the given line is

T(t) = d/dt ⟨-2 - 3t, 1 - 4t, -5t⟩ = ⟨-3, -4, -5⟩

Here,

[tex]\rm r_0 = (-2,-4,0) \ and \ v=(-3, \ -4, \ -5)t\\\\[/tex]

Then,

[tex]r = (-2, \ -4, \ 0) +(-3, \ -4, \ -5)t\\\\[/tex]

x = -2-3t, y = -4-4t, and z = 0-5t

Answers

Answer:

28 & 37 cm

Step-by-step explanation:

Perimeter(P)=9 cm

Let the equal sides(a) be x cm, then third side(b)=(x+9)cm

We have,

P=Sum of all sides

93=a+a+b

or,93=2a+(x+9)

or,93=2x+x+9

or,93-9=3x

or,84/3=x

therefore, x=28

Now,

Length of equal sides=x=28cm

Therefore, The length of each of the two equally long sides is 28 cm

The length of the longer side=(x+9)=28+9=37cm

Ken needs a total of $410 to buy a new bicycle. He has $35 saved. He earns $15 each week delivering newspapers. How many weeks will Ken have to deliver papers to have enough money to buy the bicycle?

Thanks so much! :D

Answers

25 weeks he’ll have all $410 :)

Answer:

25 weeks

Step-by-step explanation:

Since we already know that he has $35 buck-a-roons saved, we can just subtract that from the cost of the bicycle to find the actual price—which would be 375. Then, we know that for every week, he gains $15 bucks. Therefore we know that 15 would be our variable so we can create the following equation:

15x + 35 = 410

15x = 375

15x/15 = 375/15

x = 25

After 25 weeks, Ken will have enough money to buy the bicycle.

Find the value of w
A. 141
B. 110
C. 80
D. 100

Answers

Answer:

141

Step-by-step explanation:

Angle Formed by Two Chords= 1/2(SUM of Intercepted Arcs)

We know z+70 = 180 since they form a straight line

z = 110

z = 1/2 ( 79+w)

110 = 1/2 ( 79+w)

220 = 79+w

220-79 = w

141 =w

The value of w is found to be 141.

ChordWhat is chord of a circle?

The line segment connecting any two locations on a circle's circumference is referred to as the chord of the circle.

It should be emphasised that the diameter is the circle's longest chord, which runs through its centre.

Relation between chord and arc:

When two chords cross inside of a circle, the angle's measure is equal to the product of the lengths of the intersecting arcs and the vertical angle, divided by two.

Formula for chord angle:

angle formed by two chords =  1/2 (sum of intercepted arcs)

Calculation for arc w:

Estimate angle z by linear pair.

z + 70 = 180

z = 110

z is the angle formed between two chord of the circle.

Thus,

z = 1/2( 79 + w)   {sum of intercepted arcs}

110 =  1/2( 79 + w)

Further solving,

w = 141

Therefore, the value of arc w comes out to be 141.

A boat takes 3 days to travel from town A to town B, but it takes 4 days to travel from town B to town A. If a motor-less raft is left alone in the water by town A, how long will it take for the raft to float to town B?

Answers

Answer:

24 days

Step-by-step explanation:

The distance from A to B equals the distance from B to A.

Let the distance between A and B be d.

3 days = 72 hours

4 days = 96 hours

speed = distance/time

speeds are in miles per hour

speed from A to B = d/72

speed from B to A = d/96

difference in speeds:

d/72 - d/96 = d/288

The speed of the water is half of the difference.

speed = d/576

When the raft floats from A to B, it uses only the speed of the water.

d/576 / d/72 = 1/8

The speed of the water is 1/8 the overall speed of the trip from A to B, so traveling by the speed of the water alone must take 8 times longer than with the boat motor.

8 * 3 days = 24 days
