Is change in math always represented as a positive number even when its negative?
beks73 [17]
I think you mean like a number decreasing at a percentage. Yea it’s gonna be positive cause like it’s a number but then it’s probably gonna say decreasing making it negative or increasing making it positive. I’m pretty sure, correct if I’m wrong.

ou live in the building on the left in the drawing, and a friend lives in the other building. the two of you are having a discus
Alenkinab [10]

Answer:

1.3

Friend is wrong

Step-by-step explanation:

Given:

friend's claim: height of his building is more than 1.50 times the height of yours

line of sight to the top edge of the other building makes an angle of 21° above the horizontal

line of sight to the base of the other building makes an angle of 52° below the horizontal

Solution:

Let A be the height of your building is A

Let B+A his building is B higher than yours.

Let the distance between the buildings is x.  

then

tan 52 = A/x

tan 21 = B/x  

A/B = tan 52 / tan 21

      =  1.27994 / 0.38386

A/B = 3.33

(A + B) / A = 1.5 0

A/A + B/A = 1.50

1 + B/A = 1.50

B/A is basically (B/x) / (A/x)

So

1+ 3.33 / 3.33

= 4.33/3.33

= 1.3

Since 1.3 is not equal to 1.5

Hence the friend's claim is wrong.

The third term of an arithmetic sequence is -8, and the fourth term is -20. What is the second term?
Ostrovityanka [42]

Answer:

the answer is 6

Step-by-step explanation:

In mathematics, an arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant. so -20 + 14 is -8 so you just have to add 14 again to -8 to get 6

may I get brainliest please?

hope this helps :)

What is the equation of the line that passes through the point (5, 4) and has a<br> slope of 6/5?
leva [86]

Answer:

y = 6/5x - 2

Step-by-step explanation:

y = mx + b

plug in values

4 = (6/5)(5) + b

simplify

4 = 6 + b

subtract 6 from both sides

-2 = b

y = 6/5x - 2
