Given a slope and a point write a perpendicular equation in standard form.
slope: -2/5
point: (-5,3)

Answer:

Non Proportional

Step-by-step explanation:

.99(2) = 1.96  1.96(2) = 3.92

That does go, therefore it's non proportional

Hope that makes sense !

Answer:

7 and 1/15

Step-by-step explanation:

4+2 then add two fifths with two thirds (convert them into a mixed number)

Write the mixed number as a sum of the whole number (6+1 1/15)

6+1 is 7

answer is 7 1/15

Answer:

  n² -n +1

Step-by-step explanation:

First differences of the terms of the sequence are ...

  3-1 = 2

  7-3 = 4

  13-7 = 6

  21-13 = 8

Second differences are ...

  4-2 = 2

  6-4 = 2

  8-6 = 2

In a quadratic sequence the coefficient of the squared term is half of the second difference value. Here, that means the squared term will be (2/2)n² = n².

__

We can find the other terms of the quadratic expression by considering the differences between n² and the actual sequence.

The sequence of n² terms is ...

  1, 4, 9, 16, 25

When we subtract these from the actual sequence, we get ...

  1-1 = 0

  3-4 = -1

  7-9 = -2

  13-16 = -3

  21-25 = -4

That is, the amount subtracted from n² is one less than the term number.

The expression for the n-th term is ...

  an = n² -n +1

Answer:

Step-by-step explanation:

A rational number is a number that can be written in the form [tex]\frac{a}{b}[/tex] where b ≠ 0.

In order to properly arrange the numbers on the number line, we need to arrange it in an ascending order.

6/3 = 2

-3/4 = -0.75

1.5 = 1.5

0.25 = 0.25

-5.4 = -1.25

The numbers written in an ascending order will be,

-1.25 = -5/4

-0.75 = -3/4

0.25

1.5

2 = 6/3

Therefore writing this on the number line, we will have it in this order:

-1.25, -0.75, 0.25, 1.5, 2

Answer: c

Step-by-step explanation:

The pair of triangles that can be proven similar by the AA ~ Postulate is triangle AXB and QXR.

The correct option is (C).

When the ratio between two triangles' sides is the same and both triangles' angles are equal, a triangle is said to have two equal sides.

Given:

In figure C,

In triangle AXB and QXR

<BAX = <QRX (given)

<AXB = QXR (Vertical opposite angle)

So, AA similarity Criteria triangle AXB and QXR is similar.

Hence, Figure C is following AA similarity.

Answer:

Immediately after she ran the mile, her heart rate was 100 beats per minute.

Step-by-step explanation:

If Kim ran a mile in Physical Education class, and after one hour of rest her heart rate was 60 beats per minute, having dropped 2/5 of the pace it had immediately after finishing running, to know what was said heart rate it is necessary to perform the following calculation:

2/5 = 0.4

Thus, her heart rate dropped 40%. Since 100-40 is equal to 60, your 60 beats are 60% of the heart rate immediately after running. Therefore, the post-exercise heart rate is derived from the following calculation:

60 = 60

100 = X

((100 x 60) / 60) = X

(6,000 / 60) = X

100 = X

Therefore, her heart rate immediately after running was 100 beats per minute.

We have

0 < π/12 < π/2

and

tan(π/12) = sin(π/12) / cos(π/12)

Both sin(x) and cos(x) are positive for 0 < x < π/2, so we expect tan(π/12) to also be positive.

Recall the double-angle identities for cosine,

cos²(x) = (1 + cos(2x)) / 2

as well as the Pythagorean identity,

tan²(x) = sec²(x) - 1

and by definition,

sec(x) = 1 / cos(x)

Putting everything together, we have

tan(x) = √(1 / cos²(x) - 1)

tan(x) = √(2 / (1 + cos(2x)) - 1)

Let x = π/12. Then 2x = π/6, and cos(π/6) = √3 / 2, so that

tan(π/12) = √(2 / (1 + cos(π/6)) - 1)

tan(π/12) = √(2 / (1 + √3 / 2) - 1)

tan(π/12) = √(4 / (2 + √3) - 1)

tan(π/12) = √(4 / (2 + √3) - (2 + √3) / (2 + √3))

tan(π/12) = √((2 - √3) / (2 + √3))

tan(π/12) = √(7 - 4 √3)
