Answer:

The temperature decreases by 5°F every 1 hour.

Step-by-step explanation:

Let x = Time (h) and y = Temperature (°F). The rate at which the temperature decreases every hour is represented by the slope of the line, that is, m = Δy/Δx.

We have the following ordered-pairs:

  • (0 h, 45 °F)
  • (5 h; 20 °F)

With these values, we can calculate the slope of the line.

m = Δy/Δx = (20 °F - 45°F) / (5 h - 0 h) = -5 °F/h

The temperature decreases by 5°F every 1 hour.

<h2>Greetings!</h2>

Answer:

Decreases by 5

Step-by-step explanation:

To find the gradient ( or slope ), this finds out how the graph is decreasing or increasing, this can be done by using the following formula:

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

Where x1 and y1 are in the same coordinate set, plug the values in:

\frac{45 - 20}{0 - 5}

\frac{25}{-5}

= -5

So every hour it decreases by 5.


<h2>Hope this helps!</h2>

Rudik [331]

Answer:

84 x^12

Step-by-step explanation:

(4x)(-3x^8)(-7x^3)

Multiply the numbers

4*-3 *-7 = 84

x* x^8 * x^3 = Add the exponents = x^(1+8+3) = x^12

84 x^12

zmey [24]

Answer:

R = 35l-215

Step-by-step explanation:

total amount they earn = 35l

however, to account for the money used to rent the machines, we have to deduct 215 from the total cost.

hence,

<u>R= 35l-215</u>

total amount they raised = 35(26)-215 = <u>$695</u>

they would lose <u>$215</u> if they were unable to aerate due to weather conditions

they could avoid this potential loss by <u>checking the weather report before renting the machines</u>

Find the distance between the two points rounding to the nearest tenth (if necessary).
Vaselesa [24]

Hey there! I'm happy to help!

Imagine the line that is created when you connect the two points (the distance between the two points).

You can create a right triangle where this distance is the hypotenuse where the two legs are the change in x and y. So, if you take those changes in x and y, you can use the Pythagorean Theorem (a²+b²=c²) to find the distance between the two points, which is the hypotenuse.

Our change in x is 9 because 9-0 is 9.

We square it

9²=81

Our change in y is 5 as -1-(-6) or -1+6 is 5.

5²=25

We add these.

81+25=106

We square root and round to the nearest tenth.

√106≈10.3

So, our distance is 10.3.

This Pythagorean Theorem method actually gives us a formula called the distance formula that you can use to find the distance between points.

\sqrt{(x_{2} -x_{1})^2+(y_{2}-y_{1})^2}

Have a wonderful day and keep on learning! :D
