Answer:
NO. Emma is not correct.
Step-by-step explanation:
✔️Initial value for Function A:
The initial value is the y-intercept of the graph. The y-intercept is the point at which the line intercepts the y-axis. From the graph given, the line intercepts the y-axis, at y = 2, when x = 0.
Initial value for Function A is therefore = 2
✔️Initial Value of Function B:
To find the initial value/y-intercept for Function B, do the following:
Using two pairs of values form the table, (2, 2) and (4, 3), find the slope:
Slope (m) = ∆y/∆x = (3 - 2) / (4 - 2) = 1/2
Slope (m) = ½
Next, substitute (x, y) = (2, 2) and m = ½ into y = mx + b, to find the intial value/y-intercept (b).
Thus:
2 = ½(2) + b
2 = 1 + b
2 - 1 = b
1 = b
b = 1
The initial value for Function B = 1
✅The initial value for Function A (2) is not the same as the initial value for Function B (1). Therefore, Emma is NOT CORRECT.

=[|4-7|+|4-8|+8|4-9|+|4-10|+|4-11|]/12=60/12=5
Answer:
See belowStep-by-step explanation:
class-1:we are given some data 3,4,5,5,5,5,5,5,5,5,6,7
we want to figure out the MAD (Mean absolute deviation) of the given database
remember that,
[tex] \rm\displaystyle \: MAD = \frac{1}{n} \sum_{i = 1} ^{n} |x_{i} - m(x)| [/tex]
where m(X) represents the mean of the given database and [tex]|x_{i}-m(X)|[/tex] tells us to subtract every data with the got mean and n represents the number of data
let figure out m(X)
[tex] \rm\displaystyle \: m(x) = \frac{3 + 4 + 5(8) + 6 + 7 }{12} [/tex]
simplify multiplication:
[tex] \rm\displaystyle \: m(x) = \frac{3 + 4 + 40 + 6 + 7 }{12} [/tex]
simplify addition:
[tex] \rm\displaystyle \: m(x) = \frac{60}{12} [/tex]
simplify substraction:
[tex] \rm\displaystyle \: m(x) = 5[/tex]
let's figure out [tex]\sum[/tex] and [tex]|x_i-m(X)|[/tex]
[tex] \displaystyle\begin{array} {|c |c| } \hline |x_{i} - m(x) | & \displaystyle\sum_{i = 1} ^{n} |x_{i} - m(x) | \\ \hline |3 - 5 | & 2 \\ \hline | 4 - 5 | &1 \\ \hline |5(8) - 5(8)| &0 \\ \hline |6 - 5|&1 \\ \hline |7 - 5| &2 \\ \hline \\ \text{total} & 5 \\ \hline\end{array}[/tex]
last part let's figure out MAD
[tex] \displaystyle \: MAD = \frac{5}{12} [/tex]
simplify division:
[tex] \displaystyle \: MAD = 0.42[/tex]
Class-2:likewise class-2
given database 7,8,9,9,9,9,9,9,9,9,10,11
figure out m(X)
[tex] \rm\displaystyle \: m(x )= \frac{7 + 8 + 9(8) + 10 + 11}{12} [/tex]
simplify multiplication:
[tex] \rm\displaystyle \: m(x )= \frac{7 + 8 + 72 + 10 + 11}{12} [/tex]
simplify addition:
[tex] \rm\displaystyle \: m(x )= \frac{108}{12} [/tex]
simplify division:
[tex] \rm\displaystyle \: m(x )= 9[/tex]
likewise
figure out [tex]\sum[/tex] and [tex]|x_i-m(X)|[/tex]
[tex] \displaystyle\begin{array} {|c |c| } \hline |x_{i} - m(x) | & \displaystyle\sum_{i = 1} ^{n} |x_{i} - m(x) | \\ \hline |7 - 9 | & 2 \\ \hline | 8- 9 | &1 \\ \hline |9(8) - 9(8)| &0 \\ \hline |10 - 9|&1 \\ \hline |11- 9| &2 \\ \hline \\ \text{total} & 5 \\ \hline\end{array}[/tex]
figure out MAD
[tex] \displaystyle \: MAD = \frac{5}{12} [/tex]
simplify division:
[tex] \displaystyle \: MAD = 0.42[/tex]

Answer:
The length is 9 feet and the width is 4 feet.
Step-by-step explanation:
Let the dimensions be L (the length) and L - 5 (the width).
From the given information the area is:
A = L(L - 5)
When L becomes L + 3 and width becomes (L - 5) -1 = L - 6 we have:
A = (L + 3)(L - 6) so
L(L - 5) = (L + 3)(L - 6)
L^2 - 5L = L^2 - 3L - 18
-2L = -18
L = 9
so the width = 9 - 5 = 4.

Farah harvests 20 pounds of tomatoes from her garden. She needs 4 4/5 pounds to make a batch of soup. Additionally, if she uses 5.6 pounds of tomatoes to make spaghetti sauce, how many batches of soup can Farah make?
Answers
Answer:
1 batch
Step-by-step explanation:
Farah needs 4 and 4/5 pounds of tomatoes & and additional 5 and 3/5 pounds of tomatoes to make soup.
4.8 + 5.6 = 10.5 pounds per soup
10.5*2 = 21 > 20 pounds
Farah would need one more pound of tomatoes in order to make 2 batches of soup. Therefore she can only make 1 batch.

Find the value of x. Round your answer to the nearest tenth.
Answers
Answer:
+4√5
Step-by-step explanation:
Note that this is a right triangle. Therefore, the lengths of the three sides are related through the Pythagorean Theorem: a^2 + b^2 = c^2, where c is the length of the hypotenuse.
Thus, x^2 + 19^2 = 21^2, or, after solving this for x^2,
x^2 = 441 - 361 = 80
x is therefore +√80, or +4√5.
Find the area and perimeter of a rectangle that has a length of (x + 24) and (x + 16). Show all work for full credit.
Answers
Answer:
Perimeter of rectangle = 4x + 80
Area = x² + 40x + 384
Step-by-step explanation:
Perimeter of rectangle = 2*(length + width)
= 2* (x + 24 + x + 16)
= 2*( x +x + 24 + 16) {Combine like terms}
= 2* (2x + 40)
Use Distributive property : a*(b +c) = a *b + a*c
= 2*2x + 2*40
= 4x + 80
Area of rectangle = length * width
= (x + 24) (x + 16) {use FOIL method}
= x*x + x*16 + 24*x + 24*16
= x² + 16x + 24x + 384 {Combine like terms}
= x² + 40x + 384

Step-by-step explanation:
Assuming that "S" represents the money in U.S. dollars, we are given the starting amount as 270 pounds.
We first need to convert the pounds into euros, since £1 = €1.11
So all we have to do is £270 × €1.11 = €299.70
Then, we need to convert euros into dollars, since €1 = $1.21
So all we have to do here is €299.70 × $1.21 = $362.637

Find the 11th term in the geometric sequence: 4, 6, 9,....
Answers
Answer:
A11 = 230.66015625
Step-by-step explanation:
hi!
the first thing that you have to do when solving for the 11th term in a geometric sequence is to find the common ratio!
I did this by dividing 6/4 = 3/2 (I did multiply this by 6 to test if it was correct, and it was)
the next thing you can do is use this formula:
An = A1*r^(n-1)
An = the nth term of the sequence
A1 = the first term in the sequence
r = common ratio
n = the number of term that you are solving for
A11 = 4*(3/2)^(11-1)
A11 = 4*(3/2)^10
A11 = 230.66015625
