Answer:

Step-by-step explanation:

we can assume that s=k/t,k is unknown constants,0.9=k/2 >> k=1.8,so

30=1.8/t >> t=0,06

Which best explains why this triangle is or is not a right triangle?
erastovalidia [21]

Answer:

<h2>This triangle is a right triangle:</h2><h2>36² + 15² = 39².</h2>

Step-by-step explanation:

If a ≤ b <c is the length of the sides of a right triangle, then:

a^2+b^2=c^2

We have

a=15\ in,\ b=36\ in,\ c=39\ in

Check the equality:

L_s=15^2+36^2=225+1296=1521

R_s=39^2=1521

L_s=R_s

It's a right triangle.

BRAINLIEST GIVEN TO BEST ANSWER
lbvjy [14]

Answer:

Slope = \frac{1}{4}

Step-by-step explanation:

Slope of a straight line passing two points (x_1,y_1) and (x_2,y_2) is given by the formula,

m = \frac{y_2-y_1}{x_2-x_1}

From the graph attached,

Line is passing through two points (20, 5) and (80, 20),

Therefore, slope of the line will be,

m = \frac{20-5}{80-20}

m = \frac{1}{4}

The slope is \frac{1}{4}.

Find the x- and y-intercepts of the graph of 10x+2y=20 State each answer as an integer or an improper fraction in simplest form.
Deffense [45]

Answer:

  • Slope: \frac{10.000}{2.000} = -5.000
  • x - intercept: \frac{10}{5} = 2.
  • y intercept: \frac{10}{1} = 10.00000.

Step-by-step explanation:

<u>Simplify:</u>

  • Simplify the equation by subtracting what is to the right of the equal sign from both sides of the equation:
  • 10*x+2*y-(20)=0.

<u>Step 1:</u>

  • Pull out like factors:
  • 10x + 2y - 20 = 2 * (5x + y - 10)

<u>Step 2:</u>

  • Equations which are never true:
  • Solve:
  • 2 = 0
  • This can't be solved.
  • A non-zero constant never equals 0.
  • Equation of a straight line:
  • Solve:  5x+y-10 = 0
  • "y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
  • In this formula:
  • y tells us how far up the line goes
  • x tells us how far along
  • m is the Slope or Gradient i.e. how steep the line is
  • b is the Y-intercept i.e. where the line crosses the Y axis
  • The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  5x+y-10  = 0 and calculate its properties
  • Calculate the y-intercept:
  • Notice that when x = 0 the value of y is 10/1 so this line "cuts" the y axis at y=10.00000
  •  y-intercept = 10/1  = 10.00000
  • Calculate the x-intercept:
  • Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 10.000 and for x=2.000, the value of y is -0.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -0.000 - 10.000 = -10.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
  •    Slope     = -10.000/2.000 = -5.000

<u>Answers:</u>

  •  Slope = -10.000/2.000 = -5.000
  •  x-intercept = 10/5 = 2
  •  y-intercept = 10/1 = 10.00000
