Answer: See the table below (attached image)

  • Row 1:  2, 3, 5
  • Row 2: 6, 9, 15
  • Row 3: 8, 12, 20
  • Row 4: 12, 18, 30
  • Row 5: 14, 21, 35
  • Row 6: 16, 24, 40
  • Row 7: 20, 30, 50
  • Row 8: 28, 42, 70

Values in bold are the missing numbers to put into the boxes in the order shown.

====================================================

Explanation:

Each row is generated by using the original row 1. We can multiply every value in row 1 by the same positive whole number.

To get row 2, we multiply everything in row 1 by the value 3

  • We have 2 cups of red paint turn into 2*3 = 6 cups
  • Then we have 3 cups of yellow turn into 3*3 = 9 cups
  • Finally, 5 cups total turn into 5*3 = 15

So that explains why 9 and 15 go in the missing boxes for row 2. Note how 6+9 = 15. The first two columns always add to the third column value.

The other rows are generated in a similar fashion.

So we have...

  • For row 3, we multiply every value in row 1 by the number 4
  • For row 4, we multiply every value in row 1 by the number 6
  • For row 5, we multiply every value in row 1 by the number 7
  • For row 6, we multiply every value in row 1 by the number 8
  • For row 7, we multiply every value in row 1 by the number 10
  • For row 8, we multiply every value in row 1 by the number 14

If you're not sure what to multiply by, pick a value that's already given in the row in question, and divide it over its corresponding counterpart in row 1.

For instance, let's say we have no idea what to multiply by for row 8. We're given that 42 is in the middle of this row. Divide this over the corresponding middle value in row 1 to get 42/3 = 14. So 14 is our multiplier here. The same idea applies to any other row.

See the table below for the filled in values.

Which equation is a quadratic model for the data set? Hint: Use a graphing calculator or a spreadsheet program.
Ivahew [28]

The equation that model a quadratic function is:  y=0.9673x²-0.8475x+10.4334

Step-by-step explanation:

A quadratic function has the form of ;

f(x) = ax²+bx+c  where a, b and c are real numbers and a≠0

For this case, equation y=0.9673x²-0.8475x+10.4334 models a quadratic function where a>0 thus the parabola opens upwards

See attached figure below to visualize the graph

Write a formula for the general term or nth term for the sequence. Then find the indicated term. five halves comma five fourths
nadya68 [22]
Sequence: 5/2, 5/4, 5/8, 5/16
a8=?

a1=5/2
a2=5/4
a3=5/8
a4=5/16

a2/a1=(5/4)/(5/2)=(5/4)*(2/5)=(5*2)/(4*5)=2/4=1/2
a3/a2=(5/8)/(5/4)=(5/8)*(4/5)=(5*4)/(8*5)=4/8=1/2
a4/a3=(5/16)/(5/8)=(5/16)*(8/5)=(5*8)/(16*5)=8/16=1/2
Ratio: r=a2/a1=a3/a2=a4/a3→r=1/2

an=a1*r^(n-1)
a1=5/2, r=1/2
an=(5/2)*(1/2)^(n-1)
an=(5/2)*[1^(n-1)/2^(n-1)]
an=(5/2)*[1/2^(n-1)]
an=(5*1)/[2*2^(n-1)]
an=5/2^(1+n-1)
an=5/2^n

n=8→a8=5/2^8
a8=5/256

Answers:
The formula for the general term or nth term for the sequence is an=5/2^n
