ANSWER

[tex]y-1= \frac{1}{3} (x- 6)[/tex]

EXPLANATION

We want to write the point-slope form of the line that passes through (6, 1) and is perpendicular to a line with a slope of -3.

The slope of this line is negative reciprocal of -3.

[tex]m = - \frac{1}{ - 3} = \frac{1}{3} [/tex]

The point-slope form is given by:

[tex]y-y_1=m(x-x_1)[/tex]

We substitute the point and the slope to get;

[tex]y-1= \frac{1}{3} (x- 6)[/tex]

Answer:

y - 1 = 1/3*(x - 6)

Step-by-step explanation:

point-slope form of a line:

y - y1 = m*(x - x1)

where x1 and y1 are the coordinates of the point included in the line and m is its slope.

Two lines are perpendicular when the multiplication of their slopes is equal to -1. In this case,

m*(-3) = -1  

m = 1/3

Replacing this slope and the coordinates of point (6, 1) we get:

y - 1 = 1/3*(x - 6)

Answer:

if p(x) is the given polynomial then -p(x) represents its additive inverse.

Step-by-step explanation:

We need to explain about what is the addictive inverse of the polynomial.

We know that additive inverse of a polynomial is basically another polynomial that adds to the given polynomial to give result 0.

which can be done by take opposite sign of each term in the given polynomial.

For example if p(x) is the given polynomial then -p(x) represents its additive inverse.

Answer:

{1, 17}

Step-by-step explanation:

x2 − 18x + 81 = 64 can be rewritten as x² - 18x + 81 = 64.

Next, x² - 18x + 81 can be rewritten as (x - 9)²

so that we now have:

(x - 9)² = 64.

Taking the sqrt of both sides, we get

x - 9 = ± 8

Then one root is x = 9 + 8 = 17, and the other is x = 9 - 8 = 1.

{1, 17} is the set of roots

Answer:

38°

Step-by-step explanation:

Angles in a triangle add up to 180° and opposite angles are equal, therefore 180°-104°=76°

76°÷2=38°

I think this is correct :)

Answer:

The correct answer is <1 = 38°

Step-by-step explanation:

From the figure we can see a parallelogram.

Opposite  angles of a parallelogram are equal.

To find the measure of <1

From the figure we get <1 + <2 = <3 + <4

<1 = <2

<1 + <2 + <3 + <4 = 360 - (2 * 104)

 = 360 - 208 = 152

<1 + <2 = 152/2 = 76°

<1 = <2 = 76/2 = 38°

Therefore measure of <1 =  38°

Answer:

Step-by-step explanation:

In a right angled triangle, we have perpendicular, hypotenuse and base.

The hypotenuse is the longest side and opposite to the right angle. the side having 90 degree angle is perpendicular.

Applying formulas we can find the values:

the formulas are : cos (Ф) = Base / hypotenuse

sin (Ф) = Perpendicular / hypotenuse

tan (Ф) = Perpendicular / Base

11. cos z

cos z = Base / hypotenuse

cos z = 12/15

12. cos C

cos C = base / hypotenuse

cos C = 38/45

13. tan C

tan C = Perpendicular/ Base

tan C = 40/30

14. tan A

tan A = Perpendicular/ Base

tan A = 21/20

15. tan C

tan C = Perpendicular/ Base

tan C = 12/35

16. tan X

tan X = Perpendicular/ Base

tan X = 30/40

17. sin Z

Sin Z = Perpendicular / Hypotenuse

sin Z = 35/37

18. sin z = Perpendicular / Hypotenuse

sin z = 30/50

Step-by-step explanation:

The equation of the given line in slope-intercept form, y = 4x + 1.

If a line has a slope of m, and a y-intercept of b, the equation of the line in slope-intercept form is y = mx + b.

The slope of the line = rise/run = 8/2

Slope (m) = 4

The y-intercept (b) = 1

Substitute m = 4 and b = 1 into y = mx + b

y = 4x + 1

[tex](x + 3) {}^{2} - 16[/tex]

Step-by-step explanation:

[tex] {x}^{2} + 6x - 7 = (x + 3) {}^{2} - (3) {}^{2} - 7 \\ = (x + 3) {}^{2} - 16[/tex]

The equation x^2 + 6x - 7 can be written in the form (x+a)^2 + b as (x + 3)^2 - 16 by completing the square.

To solve this, we will complete the square for the polynomial x^2 + 6x - 7. The equation (x+a)^2 + b involves squaring a binomial (x+a) and adding a constant. Completing the square can convert x^2 + 6x - 7 to this form.

Step 1: Half of the coefficient of x is (6/2)=3 so a=3. Then we square a to get a^2 = 9.

Step 2: We adjust the original equation by subtracting and adding a^2 within it: (x^2 + 6x + 9) - 9 - 7.

Step 3: Simplify the equation to get (x + 3)^2 - 16, which is the form we desired.

Answer:

The width of the rectangle is  [tex]9\ units[/tex]

Step-by-step explanation:

Let

x----> the length of rectangle

y----> the width of rectangle

we know that

The area of rectangle is equal to

[tex]A=xy[/tex]

[tex]A=36\ units^{2}[/tex]

so

[tex]36=xy[/tex] ------> equation A

[tex]x=y-5[/tex] -----> equation B

substitute equation B in equation A and solve for y

[tex]36=(y-5)y[/tex]

[tex]y^{2}-5y-36=0[/tex]

Solve the quadratic equation by graphing

The solution is [tex]y=9\ units[/tex]

see the attached figure

therefore

The width of the rectangle is  [tex]9\ units[/tex]

Answer: 9 units.

Step-by-step explanation:

Let x be the width of the rectangle .

Then, the length would be x-5.

Area of rectangle = Length x Breadth

[tex]=(x-5)x=x^2-5x[/tex]

Since ,  The area of the rectangle is 36 units.

[tex]\Rightarrow\ x^2-5x=36\\\\\Rightarrow\ x^2-5x-36=0\\\\\Rightarrow\ x^2-9x+4x-36=0\\\\\Rigtarrow\ x(x-9)+4(x-9)=0\\\\\Rightarrow\ (x-9)(x+4)=0\\\\\Rightarrow\ x=9 , -4[/tex]

But width cannot be negative , so width = x= 9 units

Hence, the width of the rectangle = 9 units.

Answer:

The common ratio for the given geometric sequence is -1/2.

Step-by-step explanation:

The common ratio in a geometric sequence is simply the number that multiplies one term to arrive at the next term. From the sequence given, we can let the common ratio be x and determine its value using any of the following set of equations;

1/2 * x = -1/4

-1/4 * x = 1/8

1/8 * x = -1/16

using the first equation;

1/2 * x = -1/4

we divide both sides by 1/2 to solve for x.

x = (-1/4)/(1/2)

x = -1/4 * 2

x = -1/2

Thus, the common ratio for the given geometric sequence is -1/2.  

Answer:

Common ratio is -1/2

Step-by-step explanation:

Common ratio is the amount between each number in a geometric sequence.

It is called the common ratio because it is the same to each number.

Common ratio is the ratio between two successive numbers in a geometric sequence.

Common is a gotten by either division or multiplication.

Therefore in the case above

1/2 x -1/2 = -1/4 ......

-1/4 x -1/2 = 1/8 ......

1/8 x -1/2 = -1/16 ....etc

Therefore our common ratio is -1/2

x^2 = x3

x^2 - 3x = 0

x(x - 3) = 0

x = 0 and x -3 = 0 or x = 3

x cannot equal zero, therefore the answer is three

The numbers that when squared equal to three times themselves are 0 and 3. This is found by solving the quadratic equation x² = 3x, which factors to x(x - 3) = 0.

To express this mathematically, we let 'x' represent the number, so the equation becomes x² = 3x. This is a quadratic equation that can be solved by rearranging the terms and factoring, resulting in x(x - 3) = 0. Applying the Zero Product Property, we have two potential solutions for x: 0 or 3. Therefore, the numbers that fit the condition are 0 and 3.

Step-by-step explanation:

Given,

ABC is a triangle,

In which AB = 12 miles, BC = 15 miles and AC = 20 miles,

By the cosine law,

[tex]BC^2 = AC^2 +AB^2 -2\times AC\times AB\times cos A[/tex]

Answer:

Step-by-step explanation:

6.75/4.5 = 1.5

To find out how many times longer Mike's ride was than Noah's, you first need to convert the mixed fractions to improper fractions. Then you divide the length of Mike's ride by Noah's ride length. The result is 1.5, meaning Mike’s bike ride was 1.5 times longer than Noah’s.

This problem falls under the category of division of fractions. The question is asking for how many times longer Mike's ride was than Noah's. In order to do this, we must divide the length of Mike's ride by the length of Noah's ride.

First, we convert the mixed fractions to improper fractions. Mike biked 6 3/4 = 27/4 miles, and Noah biked 4 1/2 = 9/2 miles.

To find how many times longer Mike's ride was than Noah's, we divide 27/4 by 9/2. This is equivalent to multiplying 27/4 by the reciprocal of 9/2 (which is 2/9).

When we perform this multiplication, we get (27/4) * (2/9) = (27 * 2) / (4 * 9) = 54 / 36. The result is 1.5, so this means Mike’s bike ride was 1.5 times longer than Noah’s bike ride.
