A group of students is arranging squares into layers to create a project. The first layer has 4 squares. The second layer has 8

squares. Which formula represents an arithmetic explicit formula to determine the number of squares in each layer?
f(1) = 4; f(n) = 4 ⋅ d(n − 1), n > 0
f(1) = 4; f(n) = 4 ⋅ d(n + 1), n > 0
f(1) = 4; f(n) = 4 + d(n + 1), n > 0
f(1) = 4; f(n) = 4 + d(n − 1), n > 0

Answer:

f(1) = 4; f(n) = 4 + d(n - 1), n > 0.

Step-by-step explanation:

This arithmetic sequence has a common difference of d with first term = 4.

f(1) = 4; f(n) = 4 + d(n - 1), n > 0.

write the slope-intercept form of the line that passes through the point (1,0) and is parallel to x-y=7. type your answer in the
Brilliant_brown [7]
  • Parallel lines have the same slope but different y intercepts.
  • turn x-y=7 into slope intercept form by isolating y which would be -y=-x+7
  • divide the equation by -1 in order to make y positive and you get y=x-7
  • So rewrite the equation with the same slope but this time solving for b
  • y=x+b
  • plug in your coordinates
  • 0=1+b
  • subtract 1 from both sides
  • -1=b
  • so your equation would be
  • y=x-1

Which of the following is the best strategy to support children in learning about shapes?
Sunny_sXe [5.5K]

The best option is C. Provide multiple worksheets with pictures of the basic shapes for children to colour.

<h3>What does the learning process in children involve?</h3>

The process of learning has often been described to include all but not limited to the following:

  • gaining new understanding,
  • learning new behaviours,
  • skills,
  • values, attitudes, and
  • preferences.

Children according to experts learn faster and easily remember what they see. Hence, providing multiple worksheets with pictures of the basic shapes for children to colour is the most cost-efficient strategy to support children in learning about shapes.
