Answer:

{13,23,33,43,53,63,73,83,93}

Step-by-step explanation:

These are the conditions given for the set.

The members of the set must 2-digit numbers, therefore it means they are in between 10 and 99.
The numbers are odd. Odd numbers are numbers that cannot be divided exactly by 2.
The numbers must have 3 in them.

So our goal is to get the set of all odd numbers between 10 and 99 that have 3 in them.

The elements of the set are:

{13,23,33,43,53,63,73,83,93}

Answer:

Subtract from the dividend an easy multiple of the divisor

Record the partial quotient in a column to the right of the problem.

Repeat until the dividend has been reduced to zero or the remainder is less than the divisor.

Add the partial quotients to find the quotient.

What is the absolute value of |4n-1|= -6

laiz [17]

Ok, so the first thing you would do is find the absolute value of the first set of numbers which would be 4n-1. Then you would start to simplify the whole equation using sadmep. You should add 1 and divide by 4.

Briana drew a rectangle with a width 5 inches shorter than its length. She measured the perimeter of the rectangle and found it

Zigmanuir [339]

P = 2(L + W)
P = 14
W = L - 5

14 = 2(L + L - 5)
14 = 2(2L - 5)
14 = 4L - 10
14 + 10 = 4L
24 = 4L
24/4 = L
6 = L.......the length is 6 inches

W = L - 5
W = 6 - 5
W = 1 <=== the width is 1 inch

If a(5,3),b(0,0) and c(-3,5) are the vertices of a triangle then the value of AB.BC is

statuscvo [17]

The dot product associated to sides AB and BC is 0.

<h3>What is the dot product generated by two sides of a triangle?</h3>

In this question we must find the dot product of two vectors associated with two surrounding sides of a triangle. First, we need to find the vectors associated to sides AB and BC:

Side BA

BA = (5, 3) - (0, 0)

BA = (5, 3)

Side BC

BC = (- 3, 5) - (0, 0)

BC = (- 3, 5)

By definition of dot product, the result associated to the two sides of the triangle is:

BA • BC = (5, 3) • (- 3, 5)

BA • BC = (5) · (- 3) + (3) · (5)

BA • BC = - 15 + 15

BA • BC = 0

The dot product associated to sides AB and BC is 0.

<h3>Remark</h3>

The statement is poorly formatted, the correct form is shown below:

If A(x, y) = (5, 3), B(x, y) = (0, 0) and C(x, y) = (- 3, 5) are the vertices of a triangle then the value of the dot product between vectors AB and BC is:

HELP ASAP PLEASE

Nonamiya [84]

Answer:

The correct option is;

5.89°

Step-by-step explanation:

The speed with which the plane flies = 350 mph

The direction of flight of the plane = N 40° E

The speed with which the wind blows = 40 mph

The direction in which the wind blows = S 70° E

Therefore, we have;

The resolution of the components of the motion of the plane, given as follows;

$S_{Plane}$ = 350 × sin(40°)·i + 350 × cos(40°)·j

The resolution of the components of the motion of the wind, given as follows;

$S_{Wind}$ = 40 × sin(70°)·i - 40 × cos(70°)·j

The resultant motion of the plane is given as follows;

$R_{Plane}$ = 262.563·i + 254.435·j

The direction of motion of the plane = tan⁻¹(262.563/254.435) ≈ N 45.9° E

Therefore, the plane's drift = Plane's Track - Plane's Heading = N 45.9° E - N 40° E ≈ 5.9° ≈ 5.89°

Therefore, the correct option is 5.89°.
