The magnitude of the resulting vector, u - v, is approximately 5.83

and its angle of direction is approximately 59.04°.

<h3>How to find the magnitude of the resulting vector?</h3>

We want to subtract vector v from vector u.

We are given;

v = <2, -3> = 2i - 3j

u = <5, 2> = 5i + 2j

u - v = 5i + 2j - (2i - 3j)

= 5i + 2j - 2i + 3j

= 3i + 5j

Resultant vector = √(3² + 5²)

Resultant vector = √34 ≈ 5.83

Angle of direction of resultant vector is;

tan θ = (5/3)

θ = tan⁻¹(5/3)

θ = 59.04°

1. Green Forest Day Camp has 43 fewer girl campers than boy campers. There are 278 boy campers. Use rounding to estimate the tot
Aleks04 [339]

Answer: 513 campers

Explanation

The total number of boys in the camp is 278

There are 43 fewer girl campers than boy

Let the total number of campers be x

Let the total number of girl campers be y

Since, there are 43 fewer girl campers than boy

Hence, the total number of girl campers is

y = Boy campers - 43

Boy campers = 278

y = 278 - 43

y = 235

Since, y is the total number of girl campers, hence, the total number of girl campers is 235

The total number of campers = number of boy campers + number of girl campers

The total number of campers = 278 + 235

The total number of campers = 513 campers

The answer is 513 camperst

ABCD is a parallelogram. Find the values of x and y. Solve for the value of z, if z=x−y.
slava [35]

Answer:

C

Step-by-step explanation:

Parallel and opposite sides of a parallelogram are equal. Hence, we can say:

x + 30 = 2x - 10

and

2y-10 = y +10

Solving first one, we get:

x + 30 = 2x - 10

30+10 = x

x = 40

Also

2y - 10 = y + 10

y = 10 + 10

y = 20

Now, z = x - y, so

z = 40 - 20 = 20

Answer C is right.

The cost c, for manufacturing x flags is given by c=x? -24x +39. Find the number of flags manufactured if the cost is $120.
IRINA_888 [86]

9514 1404 393

Answer:

  27

Step-by-step explanation:

You want to find x when c = 120.

  120 = x^2 -24x +39

  x^2 -24x -81 = 0 . . . . . . subtract 120 to put in standard form

  (x -27)(x +3) = 0 . . . . .  .factor it

Solutions are ...

  x = 27, x = -3 . . . . . values of x that make the factors zero

The number of flags manufactured for a cost of $120 is 27 flags.
