^ = power to
can u answer this now please its urgent i only got 2 mars how do i get the other 2 marks and the bottom bit of the question got me 2 marks thew top bit didnt get me anything
Answers
Answer:
x = 11 / x = - 4
Step-by-step explanation:
x² - 7x - 34 = 10
x² - 7x - 34 - 10 = 10 - 10
x² - 7x - 44 = 0
x² + 4x - 11x - 44 = 0
x (x + 4) - 11 ( x + 4) = 0
(x - 11)(x + 4) = 0
(x - 11) = 0 / (x + 4) = 0
x = 11 / x = - 4

Answer:
The equation would be 8n + 11 = 3n + 26.
Answer:
I'm gonna assume we're talking about "n".
b) 8n+11=3n+26 (because they are corresponding angles)
n=3
Step-by-step explanation:
8n+11=3n+26
simplifying:
8n-3n+11-11=3n-3n+26-11
5n=15
n=3

Please make sure the answer is correct
Answers
Answer:
B
Step-by-step explanation:
First, find the slope by using change in y divided by change in x.
Change in y = 5 - 2 = 3
Change in x = 2 - 1 = 1
This means that the slope is 3/1 = 3.
Then, you put it in the point-slope form so:
(y - 2) = 3(x - 1)

Answers
Given:
The data set is 60, 74, 70, 70, 50, 62, 54, 89, 67, 88, 82, 74.
To find:
The IQR and outliers.
Solution:
The given data set is
60, 74, 70, 70, 50, 62, 54, 89, 67, 88, 82, 74
Arrange the data values in ascending order.
50, 54, 60, 62, 67, 70, 70, 74, 74, 82, 88, 89
Divide the data set in two equal parts.
(50, 54, 60, 62, 67, 70), (70, 74, 74, 82, 88, 89)
Divide each parentheses in two equal parts.
(50, 54, 60), (62, 67, 70), (70, 74, 74), (82, 88, 89)
Now,
[tex]Q_1=\dfrac{60+62}{2}[/tex]
[tex]Q_1=\dfrac{122}{2}[/tex]
[tex]Q_1=61[/tex]
And,
[tex]Q_3=\dfrac{74+82}{2}[/tex]
[tex]Q_3=\dfrac{156}{2}[/tex]
[tex]Q_3=78[/tex]
We know that, the inter quartile range is
[tex]IQR=Q_3-Q_1[/tex]
[tex]IQR=78-61[/tex]
[tex]IQR=17[/tex]
The IQR is 17.
If the data values lie outside the interval [tex][Q_1-1.5IQR,Q_3+1.5IQR][/tex], then those values are known as outliers.
[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[61-1.5(17),78+1.5(17)][/tex]
[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[35.5,103.5][/tex]
All data values lie in the interval [35.5,103.5]. So, there are no outliers.
Therefore, the correct option is B.

The absolute value function: f(x)= a|x-h|+k
The parabola (Vertex form of a quadriceps function): f(x)= a(x-h)^2+k

The slope of the line that passes through the point (3, -10.5) and (7.-28.5) will be -5
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
The slope of the line is calculated as follows:
m = Δy/Δx
Given that the line that passes through the points (3, -10.5) and (7.-28.5)
To find the slope of the line that passes through points (3, -10.5) and (7.-28.5).
Therefore, the slope of the line is;
m = Δy/Δx
m = (-28.5- 10.5)/(7 - 3)
m = -20/4
When we simplify it, then we get;
m = -5
Hence, the slope of the line is -5.

Devin jumped off a cliff into the ocean in Acapulco while vacationing with his family. His height as a function of time could be modeled by the function h(t)= -16t square root 2 +16t +96, where T is the time in seconds and H is the time in feet. How many seconds until Devon hit the water? Around to the nearest tenth is necessary.
Answers
Answer:
3 seconds
Step-by-step explanation:
Given the height modelled by the function
h(t) = -16t² + 16t + 96
The hit the water at h(t) = 0
0 = -16t² + 16t + 96
Divide through b y -16
0 = t² - t - 6
t² - t - 6 = 0
t² - 3t+2t - 6 = 0
t(t-3)+2(t-3) = 0
t+ 2 = 0 and t - 3 = 0
t = -2 secs and t = 3secs
Since t can't be negative, hence;
t = 3 secs
hence it will take 3 seconds until Devon hit the water
