The graph that correctly represents f(x) = –2(x + 4)² is graph (B).
What is a graph?A graph is a diagram that depicts the connections between two or more objects. A pie chart is a type of graph. In discrete mathematics, a graph is made up of vertices—a collection of points—and edges—the lines connecting those vertices. In addition to connected and disconnected graphs, weighted graphs, bipartite graphs, directed and undirected graphs, and simple graphs, there are many other types of graphs.So, graph of: f(x) = –2(x + 4)²
Then,
f(x) = -2(x + 4)² f(x) = (-2x - 8)²Now, plot (-2x - 8)² on the graph.
(Refer to the graph attached below)
Therefore, the graph that correctly represents f(x) = –2(x + 4)² is graph (B).

The linear regression equation model obtained from the online regression equation is :
y = 0.75x + 5 ; where ;
y = weekly sales ; x = test score ; 0.75 = slope / gradient ; 5 = intercept
sales if the test score of a salesman is 65.
y = 0.75x + 5
x = 65
y = 0.75(65) + 5
y = 48.75 + 5
y = 53.75

Answers
Answer: the mode is 67.2
Step-by-step explanation:
Given that;
Data Frequency
30 - 34 1
35 - 39 0
40 - 44 3
45 - 49 7
50 - 54 5
55 - 59 10
60 - 64 10
65 - 69 21
70 - 74 12
Mode = ?
we know that mode is the number that has the highest number of appearance of frequency, so in this case, the data group that has the highest frequency (21) is 65 - 69
Lower class boundary of the modal group; L = 65
Frequency of the group before the modal group; Fm-1 = 10
Frequency of the modal group; Fm = 21
Frequency of the group after the modal group; Fm+1 = 12
Group width; G = 4
Now using the formula
Mode = L + [ (Fm - Fm-1) / ( (Fm - Fm-1) + (Fm - Fm+1) ) ] × W
so we substitute
Mode = 65 + [ (21 - 10) / ( (21 - 10) + (21 - 12) ) ] × 4
= 65 + [ 11 / 20] × 4
= 65 + 2.2
= 67.2
Therefore the mode is 67.2

Answer:
x=3
Step-by-step explanation:
First start by simplifying the right side which is -5(x-8)+4. Apply the distributive property to have -5x-5*-8+4. Then simplify to -5x+40+4, and then to -5x+44. Now you are left with 14+5x = -5x+44. Move -5x to the left side, which now makes it positive, and do 5x+5x to have 14+10x=44. Now move 14 to the right side and subtract it from 44 to get 10x=30. Now divide both sides by 10 to have x=3.
Answer:
x=-5
Step-by-step explanation:
14 + 5x = -5(x-8)+4
14+5x=-5x+40+4
14+5x=-5x+44
14+10x=44
10x=30
x=3

From a population of 200,000,000 elements, the standard deviation is known to be 14. A sample of 49 elements is selected. It is determined that the sample mean is 56. The standard error of the mean is
Answers
Answer:
The standard error of the mean = 2
Step-by-step explanation:
Given that:
The standard deviation σ = 14
The sample size n = 49
The sample mean [tex]\overline x[/tex] = 56
The formula for calculating the standard error can be expressed as:
[tex]S.E = \dfrac{\sigma}{\sqrt{n}}[/tex]
[tex]S.E = \dfrac{14}{\sqrt{49}}[/tex]
[tex]S.E = \dfrac{14}{7}[/tex]
S.E = 2
Therefore, the standard error of the mean = 2

sin^2(a+b)-sin^2(a-b)=sin(2a)sin(2b)
Answers
Answer:
Step-by-step explanation:
To prove sin(a+b)*sin(a-b)=cos^2b-cos^2a
we simplify the left side sin(a+b)*sin(a-b) first
sin(a+b) = sin a cos b + cos a sin b
sin(a-b) = sin a cos b - cos a sin b
sin(a+b)*sin(a-b) = (sin a cos b + cos a sin b) x (sin a cos b -cos a sin b)
sin a cos b((sin a cos b + cos a sin b) - cos a sin b (sin a cos b + cos a sin b)
open the bracket
sin a cos b(sin a cos b) + sin a cos b(cos a sin b) -cos a sin b (sin a cos b)+ cos a sin b ( cos a sin b)
sin²a cos²b + sin a cos b cos a sin b - cos a sin b sin a cos b + cos²a sin²b
sin²a cos²b + 0 + cos²a sin²b
sin²a cos²b + cos²a sin²b
sin²a = 1-cos² a
sin²b = 1-cos² b
(1-cos² a)cos² b - cos² a(1-cos² b)
= cos² b - cos² a cos² b - cos² a +cos² a cos² b
choose like terms
cos² b - cos² a - cos² a cos² b + cos² a cos² b = cos² b - cos² a + 0
cos² b - cos² a

Divide 5 liters in the ratio 11:5:9. Give your answer in milliters.
Answers
Answer: we have 2,200milliters, 1000milliters, 1800milliters.
Step-by-step explanation:
Step 1
1 Liter= 1000 millilitres
5 liters = 5000 millilitres
Step 2
Dividing 5000 ml in the ratio 11:5:9
First, we find the Total ratio = 11+5+9 = 25
Such that
First part = 11/25 x 5000 = 2,200milliters.
Second Part = 5/25 x 5000=1000milliters.
Third part =9/25 x 5000=1,800milliters.
