Consider the following vectors in polar form.

|u| = 2 at ∠0°

|v| = 4 at ∠45°

What is the magnitude of vector w, if w = u – v?

|w| = 2.77
|w| = 2.95
|w| = 3.58
|w| = 5.60

Step-by-step explanation:

NEED HELP ASAPConsider The Following Vectors In Polar Form.|u| = 2 At 0|v| = 4 At 45What Is The Magnitude
Answer 2

The magnitude of w is |w| = 2.95 , Option B is the correct answer.

What is a Vector ?

Any object that has both magnitude and direction is called a Vector.

It is given that

|u| = 2 at 0 degree

|v| = 4 at 45 degree

The magnitude of the vector w = | u -v| = ?

The resultant angle will be 45 degree

By applying Cosine law

w = | u -v| = [tex]\rm \sqrt { u^2 + v^2 - 2*u*v*cos \theta}[/tex]

w = | u -v| = [tex]\rm \sqrt { 2^2 + 4^2 - 2*2*4*cos 45^o}[/tex]

w = 2.947 = 2.95

Therefore the magnitude of w is |w| = 2.95 , Option B is the correct answer.

Jack can long-jump 195% of his height with a running start. If Jack is 50 inches tall, how far can he long-jump?

Answers

Answer: 97.5 in

1.95 x 50 = 97.5

Jack can jump upto 97.5 inches.

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Jack who can long-jump 195% of his height with a running start.

Assume that he can jump a height of [x] inches. So -

x = 195% of 50

x = (195/100) x 50

x = 97.5 inches

Therefore, Jack can jump upto 97.5 inches.

Answers

Answer:

Given that x=5, when we substitute in 5 for 2x + 3 = 13, the equation will turn out to be true.

Step-by-step explanation:

2x + 3 = 13       x=5

2(5)+3=13

10+3=13

13=13

2x + 3 = 13

x=5

2(5)+3=13

Area of circle = 200.96 units²

Step-by-step explanation:

The formula to find the area of a circle is: πr², where r is the radius (which is half of the diameter)

So the diameter is 16 and of 16 is 8, which is the radius.

Sub it into the formula of a circle and you would get the area of a circle.

Select the correct answer. Which statement is true about this equation? -9(x + 3) + 12 = -3(2x + 5) − 3x A. The equation has one solution, x = 1. B. The equation has one solution, x = 0. C. The equation has no solution. D. The equation has infinitely many solutions.

Answers

Answer:

its D

Step-by-step explanation:

-9(x + 3) + 12 = -3(2x + 5) − 3x

-9x-27+25 = -6x-15-3x

-9x-15 = -9x - 15

same on both sides

so x has infinitely many solutions

The equation has no solutions. Option C is correct.

To figure out which statement is true for equation -9(x + 3) + 12 = -3(2x + 5) − 3x.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
-9(x + 3) + 12 = -3(2x + 5) − 3x.
Simplification,
LHS
= -9(x + 3) + 12

= -9x -21 + 12
= -9x -9

RHS,
=  -3(2x + 5) − 3x
= -6x - 15 - 3x
= -9x - 15
Equation RHS and LHS,
-9x - 15 = -9x -9
-15 = -9
Implies, the value of x terminate means the given expression has no solution,

Thus, the equation has no solutions. Option C is correct.

The balance of a loan is $2,570 in January, and the monthly payment is $125.50. The relationship between the loan balance, y, and the number of monthly payments made since January, x, can be represented by the equation y = 2,570 - 125.50x. In what months does the loan balance, y, meet the condition, $1,600 < y < $2,000? January February March April May June July August September October November December

Answers

Answer:

600<2570-125.5x<2000  subtract 2570 from all terms...

-970<-125.5x<-570  divide all terms by -125.5 (and reverse signs because of division by a negative!)

7.73>x>4.54  and x is months since January, and since months can only be integers...

x=[5,7]

So January + 5, 6, and 7 respectively are the three months that satisfy the equation...

June, July, and August.

6. If m∠COD=8x+13, m∠BOC=3x-10, and m∠BOD=12x-6, find m∠BOD

Answers

Answer:

Step-by-step explanation:

Given

m∠COD=8x+13,

m∠BOC=3x-10, and

m∠BOD=12x-6

The following addition property is true;

<BOD = <BOC + <COD

Substitute

12x-6 = 3x-10+8x+13

12x-6 = 11x+3

12x-11x = 3+6

x = 9

Get <BOD

<BOD = 12x-6

<BOD = 12(9)-6

<BOD = 108-6

<BOD = 102°
