What is the formula for the nth term of the given sequence 100, 20, 4, …

Naily [24]

Answer:

$a_n=100 \left(\dfrac15\right)^{n-1}$

Step-by-step explanation:

General equation of geometric sequence: $a_n=ar^{n-1}$

Given:

a₁ = 100
a₂ = 20
a₃ = 4

$\implies a_1=a=100$

$\implies a_2=100 \cdot r=20$

$\implies a_3=100 \cdot r^2=4$

Common ratio:

$r=\dfrac{a_3}{a_2}=\dfrac{4}{20}=\dfrac15$

Therefore:

$a_n=100 \left(\dfrac15\right)^{n-1}$

If the dimensions of a parallelogram are doubled, the perimeter will also be doubled. True False

Luda [366]

the answer is true. if you have square with 4 cm on all sides and double it, it will become 8 cm on all sides. the first square has a perimeter of 16 and the second square has a perimeter of 32. therefore the perimeter doubles.

Answer: 177.5

Step-by-step explanation:so to find to area u need to multiply 16 times 16,which gives u a area of 256. Now to find to Area of circle u need to do 5*5 becuse 5 is the radius,and that is 25. 25*3.14=78.5. So we need to subtract 256-78.5=177.5.

Write out how you found the answer.

ollegr [7]

Step-by-step explanation:

DC = DF + FE + EC = 3 + 14 +6 = 23 in $(\because FE = AB)$

Area of trapezoid ABCD

$= \frac{1}{2} (AB + CD) \times BE \\ \\ = \frac{1}{2} (14 + 23) \times 8 \\ \\ = 37 \times 4 \\ \\ = 148 \: {in}^{2}$
