Given:

The temperature recorded at 10:00 am is 8 degrees Fahrenheit.

The temperature decreases by 3 degrees Fahrenheit each hour.

To find:

The temperature at 2:00 pm on the same day.

Solution:

Let y represent the temperature after x hours since 10:00 am.

The temperature at 10:00 am serves as the initial temperature.

Thus, the y-intercept of the linear equation is 8.

The temperature reduces by 3 degrees Fahrenheit every hour.

This indicates the slope of the linear equation is -3, with the negative sign indicating a decrease.

The slope-intercept form of a linear function is indicated by

y=mx+b

where m is the slope and b is the y-intercept.

Inserting m=-3 and y=8 into the above equation gives us the required values.

y=-3x+8

From 10:00 am to 2:00 pm spans 4 hours; therefore, substitute x=4 into the above equation.

y=-3(4)+8

y=-12+8

y=-4

Consequently, the temperature at 2:00 pm is -4 degrees Fahrenheit.

How does the value of the digit 8 in 1.8 compare to the value of the digit 8 in 486?
Zina [12379]

Answer:

refer to the process

Step-by-step explanation:

We see that

1.8=1+0.8

486=400+80+6

Thus,

The value of the digit 8 in 1.8 is 0.8

While the value of the digit 8 in 486 is 80

Now dividing these values

80/0.8=100

So

The value of the digit 8 in 486 is 100 times larger than that of the digit 8 in 1.8

or

The value of the digit 8 in 1.8 is 100 times smaller compared to the value of digit 8 in 486

A can of peas weighs 10 oz. Explain how you would make a graph to model the total weight of peas in terms of the number of cans
babunello [11817]
On the x-axis, represent the number of cans, while on the y-axis, denote the weight in ounces.

The x-axis (number of cans) should be labeled in increments of 1, ranging from 0 to 4
and the y-axis (weight) in intervals of 10, extending from 0 to 40

The equation would be: y = 10x
The points that lie on this line are: (0,0), (1,10), (2,20), (3,30), (4,40)

Draw a diagram in which segment AB intersects segment CD equals segment CB
lawyer [12517]
The correct illustration is provided.

Explanation:

Utilizing a tool like Geogebra, commence by creating a line segment. Label the endpoints as C and D.

Next, draw the perpendicular bisector of the segment and denote the intersection with CD as B, then introduce a point A above this line.

Measure the distance from C to B and from B to D. Both distances will be equal.

Measure the length from A to B. If this distance is not equal to that from C to B, adjust A along line AB until the distances match.

With a compass and straightedge:

First, create segment CD and ensure the endpoints are labeled.

Adjust your compass to slightly more than half the distance between C and D. With it set at C, draw an arc above CD.

Using the same compass setting at D, draw another arc to intersect your first arc above CD. Mark the intersection as E.

Connect E to CD with a straightedge and label the intersection as B.

Set your compass to the distance from C to B. Position it on B and mark an arc on EB. Designate this intersection point as A.

Thus, AB will equal both CB and BD.

What is a rational number that is located between 31.5 and 31.6
Svet_ta [12734]
A rational number refers to any number that can be written as a fraction, such as 2, -3, 2/3, etc.

Essentially, any non-repeating number found between 31.5 and 31.6 would suffice.

Examples include: 31.51, 31.52, 31.568, 31.599

I suggest 31.55 since it’s straightforward and can be expressed as the fraction: 361/20

You are setting up a zip line in your yard. You map out your yard in a coordinate plane. An equation of the line representing th
lawyer [12517]

To address this issue, we will utilize the formula for determining the distance from a point to a line.

The formula is:

distance = | a x + b y + c | / sqrt (a^2 + b^2)

 

We have the line equation:

y = 2 x + 4

Rearranging it results in:

<span>y – 2 x – 4 = 0 --> a = -2, b = 1, c = -4</span>

 

The coordinates given are:

(-4, 11) = (x, y)

 

Substituting into the distance formula:

distance = | -2 * -4 + 1 * 11 + -4 | / sqrt [(- 2)^2 + (1)^2]

distance = 15 / sqrt (5)

distance ≈ 6.7

 

<span>Thus, the tree is approximately 6.7 ft from the zip line.</span>
