What is the explicit formula for this arithmetic sequence?
-12,-17, -22, -27, ...
Answer:
Step-by-step explanation:
An explicit arithmetic formula in standard form is
[tex]A_n=a_1+d(n-1)[/tex] where n is the position of a number in thesequence, a1 is the first number in the given sequence, and d is the common difference. The common diff here is -5 since we have to subtract 5 from each term to get to the next one in the sequence. The first number is -12. So
a1 = -12
d = -5 and the explicit formula is
[tex]A_n=-12-5(n-1)[/tex] and you could simplify it a bit to
[tex]A_n=-12-5n+5[/tex] and finally to
[tex]A_n=-5n-7[/tex] which is a linear representation. Arithmetic sequences can all be simplified down to represent lines.

Answer:
21√6
Step-by-step explanation:
Here we are to combine 2√54 and 5√24, and want to find any factor that these two quantities may have in common.
2√54 can be factored: 2√54 = 2√9√6, or 2[√6√9], or 6√6
Similarly, 5√24 =5√6√9, or 15[√6]
These two results can and should be added together: 7*3√6 = 21√6

Which of the following is the equation of the line in slope-intercept form that has a slope of -2 and
passes through the coordinate (4, 1)?
A) y = –2x - 7
B) y -1 = -2(x - 4)
C) y = -2x + 9
D) y = -2x
Answer:
c). y = -2x + 9
Step-by-step explanation:
y = -2x + b
1 = -2(4) + b
1 = -8 + b
9 = b

Seventy weather balloons were sent up. Twenty-eight were found. What percent wer ound? 17
Step-by-step explanation:
let the percent of found balloons be x
given,
total number of balloons= 70
number of found balloons= 28
according to the question,
x% of 70= 28
x/100 × 70 = 28
x=40
hence 40% of the balloons were found

Answer:
1. $40
2. 10 computers
3. 300 miles
Step-by-step explanation:
1. Time between 12:00 and 2:00 is 2 hours, the difference in the money is $10, so the money earned per hour is $5. 5:00 is 3 hours from 2:00, so 25+5*3 is 40, or $40.
2. Time between 1:00 and 3:00 is 2 hours, and the difference in the numbers of computers fixed is 2, so the number of computers fixed per hour is 1. 6:00 is 3 hours from 3:00, so 7+3*1 is 10, or 10 computers.
3. Time between 6:00 and 9:00 is 3 hours and the difference in the distance is 150 miles, so the miles traveled per hour is 50. 12:00 is 3 hours from 9:00, so 150+50*3 is 300, or 300 miles.
Consider the relation y → 4 x−1 for the domain {3, 5, 7, 9}
(a) Calculate the values for the range.
Answer:
{ 11, 19, 27, 35 }
Step-by-step explanation:
To find the range substitute each value of x from the domain into the relation
x = 3 : y → 4(3) - 1 = 12 - 1 = 11
x = 5 : y → 4(5) - 1 = 20 - 1 = 19
x = 7 : y → 4(7) - 1 = 28 - 1 = 27
x = 9 : y → 4(9) - 1 = 36 - 1 = 35
range is { 11, 19, 27, 35 }

Answer:
[tex]b=\frac{1}{6}[/tex]
Step-by-step explanation:
In [tex]f(x)=a\cos(b(x-c))+d[/tex], [tex]b[/tex] represents a constant related to the period of the function. Here's how it's related:
[tex]b=\frac{2\pi}{T}[/tex], where [tex]T[/tex] is the period of the function.
We're given [tex]T=12\pi[/tex], so solving for [tex]b[/tex]:
[tex]b=\frac{2\pi}{12\pi}=\boxed{\frac{1}{6}}[/tex]
Please help me with this question??m
Answer:
75
Step-by-step explanation:
f(1) = 7
f(n) = 3f(n-1) + 3
So what you are trying to do here is find the recursive value (that's what it is called) for f(n). Computers love this sort of thing, but we humans have to do it slowly and carefully.
So let's try f(2)
That means that f(2) = 3*f(n-1) + 3
but if f(2) is used it means that you have to know f(2-1) which is just f(1) and we know that.
so f(2) = 3*f(1)+3
f(2) = 3*7 + 3
f(2) = 21 + 3
f(2) = 24
Now do it again. We now know F(2), so we should be able to find f(3)
f(3) = 3*f(3 - 1) + 3
f(3) = 3*f(2) + 3 We know that f(2) = 24
f(3) = 3* 24 + 3
f(3) = 72 + 3
f(3) = 75
How do you do this ?
Answer:
the answer is- g= 72/d minus f/d
