Answer:
(x1, y1) = (3, 1)
(x2, y2) = (2,4)
the slope is
m= y2−y1/x2−x1 = 4-1/2-3 = 3/-1 = -3

i really need help i don't get it
Answer:
The correct answer is: Find half the difference of 14 and 6, multiply by 6, then add 4.
Step-by-step explanation:
By Hierarchy Rules of Operators, we must follow these steps:
(i) Subtract 6 from 14.
[tex]\frac{1}{2}\times 8\times 6 + 4[/tex]
(ii) Multiply the result in (i) by [tex]\frac{1}{2}[/tex] and 6.
[tex]24+4[/tex]
(ii) Add 4 to the result in (ii).
[tex]28[/tex]
Hence, the correct answer is: Find half the difference of 14 and 6, multiply by 6, then add 4.

Jack’s BBQ has a policy of adding a 16% tip if u have a party of 8 or more. Write an equation to represent the relationship between tip(t) and the bill(b). Then determine how much the tip would be if the bill is $145. (I need it as fast as possible, WILL GIVE BRAINLIST)
Answer:
B x 0.16 = T
If the bill is $ 145, the tip will be $ 23.2.
Step-by-step explanation:
Since Jack’s BBQ has a policy of adding a 16% tip if there is a party of 8 or more, to write an equation to represent the relationship between tip (t) and the bill (b), the following reasoning must be performed:
B x 0.16 = T
B is the value of the bill after consumption.
In turn, to determine how much the tip would be if the bill is $ 145, the following calculation must be performed:
145 x 0.16 = T
23.2 = T
Thus, if the bill is $ 145, the tip will be $ 23.2.

Given the following data set:
10,10,10,12,14,16,16,18,18,18. At what percentile is
14?
Please help
Answer:
40%
Step-by-step explanation:
x = # of values below x/n * 100
14 = 4/10 * 100
14 = 40
In the data set 10,10,10,12,14,16,16,18,18,18, 40 percentile is 14.
What is Percentile?A percentile is a comparison score between a particular score and the scores of the rest of a group
The given data set is
10,10,10,12,14,16,16,18,18,18
ten, ten , ten, twelve, forteen , sixteen, sixteen, Eighteen, Eighteen, Eighteen
The formula to find percentile is given below
Percentile rank of X=# of values below x/n ×100
Percentile rank of 14=4/10×100
Percentile rank of 14=0.4×100
=40%
Hence 40 Percentile is 14 in given data.

Evaluate when
a =3 b= 4.5 and h = 6
Answer:
For Example: Evaluate a2b for a = –2, b = 3, c = –4, and d = 4.
Step-by-step explanation:
To find my answer, I just plug in the given values, being careful to use parentheses, particularly around the "minus" signs. Especially when I'm just starting out, drawing the parentheses first may be helpful:
a2 b
( )2 ( )
(–2)2 (3)
(4)(3)
12
Note how using parentheses helped me keep track of the "minus" sign on the value of a. This was important, because I might otherwise have squared only the 2, ending up with –4, which would have been wrong.
By the way, it turned out that we didn't need the values for the variables c and d. When you're given a big set of expressions to evaluate, you should expect that there will often be one or another of the variables that won't be included in any particular exercise in the set.
Evaluate a – cd for a = –2, b = 3, c = –4, and d = 4.
In this exercise, they've given me extra information. There is no b in the expression they want me to evaluate, so I can ignore this value in my working:
(–2) – (–4)(4)
–2 – (–16)
–2 + 16
16 – 2

Bismuth-210 has a half-life of 5 days. Find
the amount of Bismuth-210 left from a
100-gram sample after 5 weeks?
Answer:
0.78125g
Step-by-step explanation:
Since there are 35 days in 5 weeks, 7 half-lives of Bismuth-210 will take place. To solve for that, you can divide 100g by 2, 7 times or simply: [tex]\frac{100}{2^{7}}[/tex]
[tex]\frac{100}{2} =50\\\frac{50}{2} =25\\\frac{25}{2} =12.5\\\frac{12.5}{2} =6.25\\\frac{6.25}{2} =3.125\\\frac{3.125}{2} =1.5625\\\frac{1.5625}{2} =0.78125[/tex]

Answer:
[tex]m = \frac{5}{7}[/tex]
[tex]m_2 = \frac{5}{21}[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (7,5)[/tex]
[tex](x_2,y_2) = (21,15)[/tex]
Using the available details, the solution goes thus:
Solving (a): The slope (m) of this line:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
This gives:
[tex]m = \frac{15 - 5}{21 - 7}[/tex]
[tex]m = \frac{10}{14}[/tex]
Simplify:
[tex]m = \frac{5}{7}[/tex]
Solving (b): Another line with 1/3 of the slope.
This is calculated using:
[tex]m_2 = \frac{1}{3} * m[/tex]
[tex]m_2 = \frac{1}{3} * \frac{5}{7}[/tex]
[tex]m_2 = \frac{5}{21}[/tex]

The transformation x=au, y=bv (a>0, b>0) can be rewritten as x/a=u, y/b=v, and hence it maps the curricular region u2+v2≤1 into the elliptical region x2/a2+y2/b2≤1. In these exercises, perform the integration by transforming the elliptical region of integration into a circular region of integration and then evaluating the transformed integral in polar coordinates.
∬R16x2+9y2dA
,where R is the region enclosed by the ellipse
(x2/9)+(y2/16)=1
Answer:
96π
Step-by-step explanation:
The transformation x = au , y = bv (a>0, b>0) can be re-written as;
[tex]\dfrac{x}{a}= u , \dfrac{y}{b}=v ;[/tex] which maps the circular region u² + v² ≤ 1 into the elliptical region
[tex]\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}\le 1[/tex]
Integrating and transforming the elliptical region into a circular region;
[tex]\int \int _R \sqrt{16x^2+9y^2}\ dA[/tex]
here;
R = region enclosed by the ellipse.
[tex]\dfrac{x^2}{9}+\dfrac{y^2}{16}=1[/tex]
Let x = 3u ; y = 4v
Jocobian = J(x,y)

So;
[tex]\int \int_R \sqrt{16x^2+9y^2 \ dA}= \int \int _D\sqrt{16(4u)^2+9(3v)^2} \ |J| dudv \\ \\ \\= 12 \int \int _D \sqrt{x^2 +v^2} \ \ (12) dudv \\ \\ \\ =144 \int \int _D \sqrt{x^2 +v^2} \ \ dudv[/tex]
Using polar coordinates;
[tex]u = rcos \theta ; v = rsin \theta \\ \\ \implies u^2+v^2 = r^2 ; dudv = rdr \theta \\ \\ limits :\\ \\ 0 \le r \le 1, 0\le \theta \le 2 \pi[/tex]
∴
[tex]\int \int _R \sqrt{16x^2 + 9y^2 }\ dA[/tex]
[tex]= 144 \int ^{2 \pi}_{0} \int ^{1}_{0} \ r (rdrd \theta) \\ \\ = 144 \int ^{2 \pi}_{0} \int ^{1}_{0} \ r^2drd \theta \\ \\ = 144 \int ^{2 \pi}_{0}(\dfrac{r^3}{3})^1_0 r d \theta \\ \\ = 144 ( \dfrac{1}{3}) \int ^{2 \pi}_{0} \ d \theta \\ \\ = 144(\dfrac{1}{3}) ( 2 \pi) \\ \\ \mathbf{= 96 \pi}[/tex]
