Answer:

slope = 40

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (2, 80) and (x₂, y₂ ) = (4, 160) ← 2 points on the line

m = \frac{160-80}{4-2} = \frac{80}{2} = \frac{40}{1} = 40

What mathematical relationship between variables is suggested by a graph showing a diagonal line from the lower left to the uppe
monitta

you can see the distance between the intervals in the graph more easily because you can see how far the plots are away from each other by connecting the w/ lines. Ex you had 5 on a graph and you had 12 after it there is an interval of 8 in between so you can visually see how far apart the numbers area simple 2d xy line graph has only the possibility for 2 different variables (x and y).. for a 3 variable graph you would have to go into a 3d xyz graph with each variable as x, y and z. it is possible to fit a line to this but for an easier analysis it is better to analyse the variables in pairs. Hope this helps.

A triangle has a perimeter of 91 cm. If the three sides of the triangle are n,4n - 2 and 5n - 7 what is the length of each side
sdas [7]

Answer:

10,38,43

Step-by-step explanation:

n+4n-2+5n-7=91

10n=91+2+7

10n=100

n=10

4(10)-2=38

5(10)-7=43

Verify that [tan(theta) + cot(theta)]^2 = sec^2(theta) + csc^2(theta)
Wittaler [7]

(tanθ + cotθ)² = sec²θ + csc²θ

<u>Expand left side</u>: tan²θ + 2tanθcotθ + cot²θ

<u>Evaluate middle term</u>: 2tanθcotθ = 2*\frac{sin\theta}{cos\theta}*\frac{cos\theta}{sin\theta} = 2

⇒ tan²θ + 2+ cot²θ

= tan²θ + 1 + 1 + cot²θ

<u>Apply trig identity:</u>  tan²θ + 1 = sec²θ

⇒ sec²θ + 1 + cot²θ

<u>Apply trig identity:</u>  1 + cot²θ = csc²θ

⇒ sec²θ + csc²θ

Left side equals Right side so equation is verified

There are 150 oranges, apples and pears in a box. The ratio of the number of oranges to the number of apples is 3:5 and the rati
Rom4ik [11]

Answer:

  Pears:  30

Step-by-step explanation:

Constant:

  3x + 5x + 2x = 150

                 10x = 150

                    x = 15  

Multiply ratio with constant from above:

  oranges : apples

       3 * 15 : 5 * 15

            45 : 75       ==>               45 oranges: 75 apples

  pears : apples

   2 * 15 : 5 * 15

        30 : 75          ==>                    30 pears: 75 apples

Check:

45 oranges + 75 apples + 30 pears = 150 fruits
