Let |r| = 17 At An Angle Of 40 And |s| = 14 At An Angle Of 160. Which Expression Represents |r + S|?ty

Answers

Answer 1

Answer:

B

Step-by-step explanation:

I got it right on edge2020, 160-40= 120

120/2 = 60 because the angle was gonna be half way between the two angles

Answer 2

The expression that represent | r+s| is Option B

What is a Vector ?

A vector is an object that has both magnitude and direction.

It is given that

|r| = 17 at an angle of 40 degree

|s| = 14 at an angle of 160 degree

| r + s| = ?

The magnitude will be determined by the cosine law

and the angle will be 60 degree , obtained from the figure attached with the answer.

[tex]\rm |r + s| = \sqrt{ 17^2 + 14 ^2 -2 * 14 *17 cos 60[/tex]

Therefore , the expression that represent | r+s| is Option B.

PLEASE ANSWER !!

The graph of a linear function f passes through the point (-2,-10) and has a slope of 5/2 what is the zero of f ?

Answers

Answer:

Check the explanation.

Step-by-step explanation:

As the graph of a linear function f passes through the point (-2,-10) and has a slope of 5/2.

As the slop-intercept form is given by:

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept.

substituting the values (-2, -10) and m = 5/2 in the slop-intercept form to determine y-intercept.

[tex]y = mx+b[/tex]

[tex]-10=\frac{5}{2}\left(-2\right)+b[/tex]

[tex]-\frac{5}{2}\cdot \:2+b=-10[/tex]

[tex]-5+b=-10[/tex]

[tex]-5+b+5=-10+5[/tex]

[tex]b=-5[/tex]

And the equation of the line in the slope-intercept form will be:

[tex]y = mx+b[/tex]

putting b = -5 and slope = m = 5/2

[tex]y = mx+b[/tex]

[tex]y=\frac{5}{2}x+\left(-5\right)[/tex]

[tex]y=\frac{5}{2}x-5[/tex]

Determining the zero of function.

As we know that the real zero of a function is the x‐intercept(s) of the graph of the function.

so let us determine the value of x (zero of function) by setting y = 0.

[tex]0=\frac{5}{2}x-5[/tex]

[tex]\frac{5}{2}x-5=0[/tex]

[tex]\frac{5}{2}x=5[/tex]

[tex]5x=10[/tex]

[tex]x=2[/tex]

Therefore, the zeros of the function will be:

x = 2

I don’t know how to do this it would be very much appreciated if someone could solve this for me thank you.

Answers

The graph of the line is B.
The answer is be because your slope would be negative 1/3 rise over run and your intercept is positive 6

Assume that y varies directly with x. If y=9 when x=−3, find x when y=6. Enter in any fractions using a / (e.g. "1/2" is the same as 1^/2).

Answers

Answer: 2

Step-by-step explanation:

This is a direct proportion. Since y varies as x. This will be:

y = kx

where,

y = 9

x= 3

9 = 3k

k = 9/3

k = 3

Find x when y=6

y = kx

6 = 3x

x = 6/3

x = 2

Step-by-step explanation: took the quiz

The length of the diagonal is 41 units.

To find the length of a diagonal.

What is rectangle?

A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees.

Let a right triangle with legs length 9 units and 40 units and hypotenuse is the diagonal length c.

[tex]a^{2} +b^{2} =c^{2}[/tex]

[tex]9^{2} +40^{2} =c^{2}[/tex]

[tex]81+1600=c^2\\1681=c^2[/tex]

sqrt both sides

41=c

So, the length of the diagonal is 41 units.

The tens digit of a two digit number is five more than the units digit. Seven times the sum of the digits of this number is 3 less than the number itself. Find the number.

Answers

Answer:

94

Step-by-step explanation:

Let the unit's digit = [tex]y[/tex]

Let the ten's digit = [tex]x[/tex]

Then the number will be equal to [tex]10x+y[/tex]

Now, using the given statement:

[tex]x=y+5 ..... (1)[/tex]

[tex]7(x+y) = 10x+y-3\\\Rightarrow 7x+7y=10x+y-3\\\Rightarrow 6y-3x=-3 ..... (2)[/tex]

Now, using the equation (1) in equation (2):

[tex]6y-3(y+5) =-3\\\Rightarrow 3y-12=0\\\Rightarrow y =4[/tex]

By equation (1):

[tex]x = 4+5 \\\Rightarrow x =9[/tex]

Therefore, the number is :

[tex]10x+y= 10\times 9 +4 = \bold{94}[/tex]
