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.

Answer:
option D. DE = 11
Step-by-step explanation:
The line DF is equivalent in length to the blue line,
(x + 7) + 7 = 4x + 2
Solve:
x + 14 = 4x + 2
subtract 14 from both sided to get x alone,
x + 14 - 14 = 4x + 2 - 14
x = 4x - 12
subtract 4x from both sided,
x - 4x = 4x - 4x - 12
-3x = -12
divided both sides by -3,
-3x / 3 = -12 / -3
x = 4
Plug in x into DE equation:
x + 7: (4) + 7 = 11

Answer: 45°
Step-by-step explanation: The formula for finding the measure of each exterior angle of a regular polygon is simply 360/n where <em>n</em> represents the number of sides of the polygon.
Since our polygon has 8 sides, we plug 8 in
for <em>n</em> and we have 360/8, which is 45.
So our answer is 45°.
A geologist in South America discovers a bird skeleton that contains 80% of its original amount of C-14
We use formula ![N = N_oe^{-kt}](https://tex.z-dn.net/?f=N%20%3D%20N_oe%5E%7B-kt%7D)
N0= initial amont of C-14 (at time t=0)
N= amount of C-14 at time t
t= time, in years
k= 0.0001
N is 80% of N0 that is ![N= 0.80N_o](https://tex.z-dn.net/?f=N%3D%200.80N_o)
![N = N_oe^{-kt}](https://tex.z-dn.net/?f=N%20%3D%20N_oe%5E%7B-kt%7D)
![0.80N_o = N_oe^{-kt}](https://tex.z-dn.net/?f=0.80N_o%20%3D%20N_oe%5E%7B-kt%7D)
Divide both sides by N_o
![0.8=e^{-0.0001 t}](https://tex.z-dn.net/?f=0.8%3De%5E%7B-0.0001%20t%7D)
Take ln on both sides
![ln(0.8)=lne^{-0.0001 t}](https://tex.z-dn.net/?f=ln%280.8%29%3Dlne%5E%7B-0.0001%20t%7D)
ln(0.8) = -0.0001t ln(e)
ln(0.8) = -0.0001t
Divide both sides by -0.001
t = 2231.435513
The age of the bird skeleton is 2231 years old
Answer:
For the table on the left the rate of change is ![22.8](https://tex.z-dn.net/?f=22.8)
For the table on the left the rate of change is ![-2](https://tex.z-dn.net/?f=-2)
Step-by-step explanation:
The range of change is the slope. The slope can be found with the following formula:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
<u>For the table on the left</u>
Choose two points. In this case you can choose (-1,-24), (4,90)
You can say that:
![y_2=-24\\y_1=90\\\\x_2=-1\\x_1=4](https://tex.z-dn.net/?f=y_2%3D-24%5C%5Cy_1%3D90%5C%5C%5C%5Cx_2%3D-1%5C%5Cx_1%3D4)
Substituting these values into the formula, you get:
![m=\frac{-24-90}{-1-4}\\\\m=22.8](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-24-90%7D%7B-1-4%7D%5C%5C%5C%5Cm%3D22.8)
<u>For the table on the right</u>
Choose two points. You can choose (3,-6), (-6,12)
You can identify that:
![y_2=-6\\y_1=12\\\\x_2=3\\x_1=-6](https://tex.z-dn.net/?f=y_2%3D-6%5C%5Cy_1%3D12%5C%5C%5C%5Cx_2%3D3%5C%5Cx_1%3D-6)
Substituting these values into the formula, you get:
![m=\frac{-6-12}{3-(-6)}\\\\m=-2](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-6-12%7D%7B3-%28-6%29%7D%5C%5C%5C%5Cm%3D-2)
