Write each sum using summation notation<br> 12 + 22 + 32 + 42 + ⋯ + 10000^2

Murljashka [212]

Answer:

50,00,70,000

Step-by-step explanation:

The given sequence is Arithmetic Progression.

Arithmetic Progression is a sequence in which every two neighbor digits have equal distances.

Here first we will find the number of terms

For finding the nth term, we use formula

aₙ = a + (n - 1) d

where, aₙ = value of nth term

a = First term

n = number of term

d = difference

Now, In given sequence: 12, 22, 32, 42, ⋯ , 100002

a = 12, d = 10, n = ? and aₙ= 100002

∴ 100002 = 12 + (n - 1) × (10)

⇒ 99990 = 10(n - 1)

⇒ n = 10000

Now using the formula of Sum of Arithmetic Sequence,

Sₙ = n÷2[2a + (n - 1)d]

⇒ Sₙ = (10000÷2)[2 × 12 + 9999 × 10]

⇒ Sₙ = 5000 [ 24 + 99990]

⇒ Sₙ = 5000 × 100014 = 50,00,70,000

Answer:

4/1. ( not so sure tho)

Step-by-step explanation:

=[(6/6)×(6/6)] + [(5/6)×(6/6)] + [(6/6)×(5/6)]

=(36/36) + (30/36) + (30/36)

=(taking LCM) 96/36

=4/1.

Task 1 Nonlinear Systems of Equations Create a system of equations that includes one linear equation and one quadratic equation.

Luden [163]

Answer:

hope this helps

Step-by-step explanation:

solution:

x^2 + 3x + 5 = x + 13

x^2 + 2x -8 = 0

(x+4)(x-2) = 0

x = -4 or x = 2

if x = -4, y = 9

if x = 2 , y = 15

Which inequality is represented by the graph?

PSYCHO15rus [73]

Answer:

Step-by-step explanation:

From the graph,

y and x intercepts are $(0,-3)$ and approximately $(1.9,0)$ respectively

for A, C and D : $y=53x-3$

x intercept the value of y=0, and y intercept x=0.

x and y intercepts are $(\frac{3}{53},0 )$ and approximately $(0,-3)$ respectively

for B: $y=35x-5$

x and y intercepts are $(\frac{3}{35},0 )$ and approximately $(0,-3)$ respectively

Therefore x and y intercepts for the lines $y\leq 53x-3,y>53x-3, y$ and $y$ they are not equal to the x and y intercepts of the given graph
