Answer:
The value of T₂₀ - T₁₅ is <u>-20</u>.
Step-by-step explanation:
<u>Given</u> :
<u>To</u><u> </u><u>Find</u> :
<u>Using Formula</u> :
General term of an A.P.

- >> Tₙ = nᵗʰ term
- >> a = first term
- >> n = no. of terms
- >> d = common difference
<u>Solution</u> :
Firstly finding the A.P of T₂₀ by substituting the values in the formula :






Hence, the value of T₂₀ is a + 19d.

Secondly, finding the A.P of T₁₅ by substituting the values in the formula :






Hence, the value of T₁₅ is a + 14d

Now, finding the difference between T₂₀ - T₁₅ :









Hence, the value of T₂₀ - T₁₅ is -20.

Answer:
16.5+13.6+12.4.17.7= 60.2
60.2÷4 =15.05
Answer: Second Choice. (3, 3)
Step-by-step explanation:
<u>Given point</u>
(x, y) = (-3, 5)
<u>Given the rule for application</u>
(-x, y - 2)
<u>Determine the new x-value</u>
x = -3
-x = - (-3) = 3
<u>Determine the new y-value</u>
y = 5
y - 2 = (5) - 2 = 3
Therefore, the result is 
Hope this helps!! :)
Please let me know if you have any questions
It is not straight and does not always pass through 0,0
so A, C, and D are incorrect.
Look up nonlinear function, and it shows a curved line.
The answer is B. It can be curved.
To find area you do length x width. To find perimeter you do length + width.
