Please help! The answer is the slope and it needs to be rounded to 3 decimal places.
The slope is 0.003
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
the coordinates are (12000, 20) and (18000, 2)
so, slope= 18 / 6000
= 0.003
The 3 in the thousandths place rounds down to 3, or stays the same, because the digit to the right in the ten thousandths place is 0.003.
Hence, the slope is 0.003.

Daniel rollerbladed 3 1/4 miles in 4 minutes. What was his speed in miles per hour?
Answer: 48 3/4 miles/hour.
Step-by-step explanation: To find Daniel's speed in miles per hour, we need to first convert the time he rollerbladed to hours. We can do this by dividing the number of minutes he rollerbladed by 60 minutes per hour, as follows:
time in hours = 4 minutes / 60 minutes/hour = 1/15 hours
We can then use the formula for speed, which is distance divided by time, to find Daniel's speed in miles per hour as follows:
speed in miles per hour = distance in miles / time in hours
speed in miles per hour = 3 1/4 miles / 1/15 hours
speed in miles per hour = 3 1/4 miles * 15 hours/1
speed in miles per hour = 48 3/4 miles/hour
Therefore, Daniel's speed in miles per hour was 48 3/4 miles/hour.
Answer:
Check explanation!
Step-by-step explanation:
Daniel rollerbladed at 15 mph, we know this because 60 divided by 4 = 15 (number of minutes in an hour divided by his time = answer)
so daniel rollerbladed at 15 mph
NO LINKS!! Each table below represents an exponential function of the form y = ab^x. Complete each table and find the corresponding equation.
Answer:
[tex]\textsf{a)} \quad y=1.8(3.2)^x[/tex]
[tex]\textsf{b)} \quad y=5(7)^x[/tex]
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{9 cm}\underline{General form of an Exponential Function}\\\\$y=ab^x$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the initial value ($y$-intercept). \\ \phantom{ww}$\bullet$ $b$ is the base (growth/decay factor) in decimal form.\\\end{minipage}}[/tex]
Part (a)Given ordered pairs:
(0, 1.8)(1, 5.76)(2, 18.432)The y-intercept is the y-value when x = 0.
Therefore, as the y-intercept is 1.8, a = 1.8.
[tex]\implies y=1.8b^x[/tex]
Substitute point (1, 5.76) into the equation and solve for b:
[tex]\begin{aligned} y&=1.8b^x\\\implies 5.76&=1.8 \cdot b^1\\5.76&=1.8b\\b&=\dfrac{5.76}{1.8}\\b&=3.2\end{aligned}[/tex]
Therefore, the exponential equation is:
[tex]\boxed{y=1.8(3.2)^x}[/tex]
To complete the given table, simply substitute the values of x into the found equation:
[tex]\begin{array}{c|l}x&\phantom{189}y\\\cline{1-2} \vphantom{\dfrac12}}0&\phantom{18}1.8\\\vphantom{\dfrac12}}1&\phantom{18}5.76\\\vphantom{\dfrac12}}2&\phantom{1}18.432\\\vphantom{\dfrac12}}3&\phantom{1}58.9824\\\vphantom{\dfrac12}}4&188.74368\end{array}[/tex]
Part (b)Given ordered pairs:
(0, 5)(2, 245)The y-intercept is the y-value when x = 0.
Therefore, as the y-intercept is 5, a = 5.
[tex]\implies y=5b^x[/tex]
Substitute point (2, 245) into the equation and solve for b:
[tex]\begin{aligned} y&=5b^x\\\implies 245&=5 \cdot b^2\\49&=b^2\\b&=\sqrt{49}\\b&=7\end{aligned}[/tex]
Therefore, the exponential equation is:
[tex]\boxed{y=5(7)^x}[/tex]
To complete the given table, simply substitute the values of x into the found equation:
[tex]\begin{array}{c|l}x&\phantom{11}y\\\cline{1-2} \vphantom{\dfrac12}}0&\phantom{1111}5\\\vphantom{\dfrac12}}1&\phantom{111}35\\\vphantom{\dfrac12}}2&\phantom{11}245\\\vphantom{\dfrac12}}3&\phantom{1}1715\\\vphantom{\dfrac12}}4&12005\end{array}[/tex]

The answer is x = -70.
To solve for x, bring the variable to one side, and bring all the remaining values to the other side by applying arithmetic operations on both sides of the equation. Simplify the values to find the result.
Multiply all terms by the same value to eliminate fraction denominators
/7 = −10
7⋅/7 = 7(−10)
Cancel multiplied terms that are in the denominator
7⋅/7 = 7 (−10)
x =7(-10)

The similarity is that Sunni and Shia Muslims agree on the fundamental tenets of Islam, such as worshiping Allah as God, acknowledging Muhammad (Peace Be Upon Him) as the Prophet, and adhering to the Quran's teachings.
The difference is that Shia place a greater emphasis on Muhammad's family ancestry through a succession of Imams than Sunnis do on imitating the Prophet and his example.

Shi'a and Sunni Muslims both use the Hadith, though they often prefer different collections of sayings.
They have different perspectives on imams. Imams are considered saints in Sunni Islam and must have a strong commitment to the Quran and Sunnah in order to be nominated.

Jerrica is 5.6 feet tall and is standing 7.4 feet from the mirror.
What is the height of the flagpole?
With the help of similar triangles the height of Flagpole is 15.13 feet
what is similar triangle?
Triangles that are similar in shape but differ in size are known as similar triangles. Examples of related objects are all equilateral triangles and squares with any side length. To put it another way, if two triangles are comparable, then their corresponding angles and sides are congruent and equal in size.
solution:
let C is the point of reflection in triangle ABC and EDC
∠ ABC = ∠ EDC ( 90 Degree)
∠ ACD = ∠ ECD ( Reflective angle )
By symmetry,
AB/ED = BC/CD

If their food and beverages cost $25.30 and there is an 8% meals tax, how much is the bill? Enter your answer to the nearest cent.
Part B
After adding a tip, the total lunch cost was $32.24. What percentage tip did they give? Enter your answer to the nearest percentage.
Answer:
Part A: The bill is $27.32
Part B: The percentage is 19%
My work:
Part A
? 8
--------- = ---------
25.30 100
equals 2.02400
then round to get the tax amount which is $2.02
to find the bill cost we need to add the tax and the cost of the meal:
2.02 + 25.30 = 27.32
Part B
to find the tip we need to subtract the bill from the total lunch cost:
27.32 + t = 4.92 (t = tip)
32.24 - 27.32 = 4.92
So now that we know the tip we can figure out how much percentage that is of the cost of the meal:
4.92 ?
-------- = --------
25.30 100
which equals 19.4466403/100
