The arithmetic sequence has a common difference, and a first term and the 17th term in the arithmetic sequence is -21
How to determine the 17th term?The given parameters are:
First term, a = 11Common difference, d = -2The nth term of an arithmetic progression is:
Tn = a + (n - 1)d
So, we have:
T17 = a + 16d
Substitute the given values
T17 = 11 - 16 * 2
Evaluate
T17 = -21
Hence, the 17th term in the arithmetic sequence is -21

Answer:
8/9n - 3
Step-by-step explanation:
Explanation:
When multiplying a fraction by a whole number, you multiply the numerator by the whole number. In this case, doing so would result in 8/9n. Because the same principle would apply for the other part of the equation, we can do 4/9 x -3 to get -12/9. -12/9 is improper, so we could standardize it to get the equation’s expression in simplified form. -12/9 simplified is -1 1/3. The answer would be 8/9n - 1 1/3 because when there is a negative factor, the expression becomes a subtraction problem. Thus, your equation is 8/9n - 1 1/3.

Given g of x equals cube root of the quantity x plus 6, on what interval is the function negative?
Answers
The interval for the function to be negative will be (-∞<x<-7).
What is a function?A function in mathematics set up a relatioship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.
Here we have a function:-
g(x) = ∛(x+6)
If we put the value of x lesser than 6 in the function we will always get a negative value so the interval will be:-
(-∞<x<-7).
Therefore interval for the function to be negative will be (-∞<x<-7).

Answer:
x = 20
y = √3 / 10
Step-by-step explanation:
The cosine ratio gives the ratio between the adjacent side and the hypotenuse.
The sine ratio gives the ratio between the opposite side and the hypotenuse.
Taking cosine ratio to find x :
cos 60° = 10/x
1/2 = 10/x
x = 20
Taking sine ratio to find y :
sin 60° = y/x
√3 / 2 = y/20
y = √3 / 10
Answer:
x= 20 , y= 10√3
Step-by-step explanation:
This question is clearly a trigonometry question
Please bare in mind :
Cos 60 = 1/2
Sin 60 = √3/2
Tan 60 = √3
Side x is the hypotenuse (h)
Side y is the Opposite (o)
And side with length of 10 is adjacent (a)
To find x, we have a, and we need h
So we use C = a/h
Cos 60 = 10/h
h = 10/Cos 60
h = 10/0.5
h = 20 , x=20
To find y, we can use pythagaros as we found the value of x :
10² + y² = x²
10² + y² = 20²
y² = 20²-10²
y² = 300
y = √300
y= √100×3 y=√100 × √3
y = 10√3
This is our y value
Another way to find y is trigonometry :
We have a and we need o so we use :
T = o/a
Tan 60 = o/10
o = 10×tan 60
o = 10×√3
o = 10√3 , y=10√3

[tex]\textsf{Volume of a cone}=\sf \dfrac{1}{3} \pi r^2 h \quad\textsf{(where r is the radius and h is the height)}[/tex]
Given:
h = 3rVolume = 343π cm³Substituting given values into the formula and solving for r:

The median is 8, so it is less than 9.
Answer:
Option D is not true
Step-by-step explanation:
The mode is the highest occuring number.From the data.
The mode is 9 and is greater than 7.This mean option A is correct.
The range is the difference between the highest number and the lowest which is 15-4 =11.Hence option C is correct because the range is more than 10.
The median when the data is arranged in either ascending or descending order i.e (15,12,11,9,9,7,5,4).Hence,the middle numbers are 9 and 9.To get the median,we get the average of the numbers which will be 9+9=18 ÷2= 9. The median is 9 which means option D is not correct.
The mean will be the addition of the numbers divided by the number of items
[tex] \frac{9 + 15 + 5 + 7 + 9 + 12 + 11 + 4}{8} [/tex]
[tex] = \frac{72}{8} [/tex]
[tex] = 9[/tex]
The mean is equal to 9 which means Option B is correct.
