Answers

Answer:

4.0541

Step-by-step explanation:

I don't know if this is correct but this is what I got.

You would take the error and divide it by the theoretical value and then multiply that by 100.

7.7 - 7.4 = 0.3

0.3 ÷ 7.4 = 0.04054054

0.04054054 x 100 = 4.05405405 (simplify) = 4.0541%

Here are two points (-3,4),(1,7) What is the slope of the line between them?

Answers

Answer:

3/4

Step-by-step explanation:

The solution is Option B.

The slope of the line between the points P ( -3 , 4 ) and Q ( 1 , 7 ) is 3/4

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P = P ( -3 , 4 )

Let the second point be Q = Q ( 1 , 7 )

Now , the slope of the line between the two points is given by the formula ,

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 7 - 4 ) / ( 1 - ( -3 ) )

On simplifying the equation , we get

Slope m = 3 / 4

Therefore , value of m is 3/4

Hence , slope of the line is 3/4

The answer is 98 degrees for y

Answer:

Step-by-step explanation:

First, you should find the angle x because it will help in solving the angle y. A straight line adds up to 180 degrees, therefore x+y = 180

For the triangle on the left, sum up the angles and set it to 180 degrees.

60 + 38 + x = 180

x = 82 degrees

Now solve for y by doing this

82 + y = 180

y = 98 degrees

While I'm here, Ill solve for z because it will most likely ask in the next question.

26 + 98 + z = 180

z = 56 degrees
