In some instances of bivariate data, it is determined that one variable influences or determines the second variable, and the terms dependent and independent variables are used to distinguish between the two types of variables. In the above example, the length of a person's legs is the independent variable.

Question
joja [24]

Answer:

The recursive rule is f(1) = first term;  f_({n}) = f_({n-1}) + d

f(1) = 55;  f_{20} = f_{19}  + 10

The explicit rule is f(n) = f(1) + (n - 1)d

f(20) = 245

Step-by-step explanation:

The recursive rule of the arithmetic sequence is

a_{1} = first term;   a_{n} = a_{n-1}  + d

Where:

  • a_{1} is the first term in the sequence
  • a_{n} is the nth term in the sequence  
  • a_{n-1} is the term before the nth term  
  • n is term number
  • d is the common difference.

The explicit rule of the arithmetic sequence is

a_{n}=a_{1}+(n-1)d

where:

  • a_{1} is  the first term in the sequence
  • a_{n} is the nth term in the sequence  
  • n is term number
  • d is the common difference

∵ The first 4 terms of the sequence are 55, 65, 75, 85

∴ a_{1} = 55

∵ d = 65 - 55

∴ d = 10

∵ We need to find the 20th term

∴ n = 20

∵ The recursive rule is f(1) = first term;  f_({n}) = f_({n-1}) + d

→ Substitute the values of a_{1}, n, and d in recursive rule

∴ f(1) = 55;  f_{20} = f_{19}  + 10

∵ The explicit rule is f(n) = f(1) + (n - 1)d

→ Substitute the values of n and d to find it

∴ f(20) = 55 + 19(10) = 245

∴ f(20) = 245

What is the vertex of the function f(x) = x2 + 12x?
saul85 [17]

Answer:

6, - 36 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

x = - \frac{b}{2a}

f(x) = x² + 12x ← is in standard form

with a = 1, b = 12, c = 0 , then

x = - \frac{12}{2} = - 6

Substitute x = 6 into f(x) for corresponding value of y

f(6) = 6² + 12(- 6) = 36 - 72 = - 36

vertex = (6, - 36 )

How do i do this, i need to find an answer fast
oksian1 [2.3K]

Answer:

y = 5√3

x = 10√3

Step-by-step explanation:

From the given sides

Adjacent = 15

Opposite = y

Hypotenuse = x

Angle of depression = 30degree

Using the SOH CAH TOA identity

tan theta = opp/adj

tan 30 = y/15

y = 15tan30

y = 15(1/√3)

y = 15√3/3

y = 5√3

Similarly

cos theta = adj/hyp

cos 30 = 15/x

x = 15/cos30

x = 15 /√3/2

x = 30/√3

x = 30√3/3

x = 10√3

Enter the value of 5 times (13.5-4.5)
vfiekz [6]
The answer is 45 because you do parenthesis first which is 13.5-4.5=9 then you multiply 9×5=45 therefore the answer is 45.
