Given the sequence

A = -4 - 6i

To find

Sum of terms from i=5 to i=15

<h3>Solution</h3>

We see the sequence is AP

The required sum is

S₅₋₁₅ = S₁₅ - S₄

Using sum of AP formula

Sₙ = 1/2n(i₁ + iₙ)

Finding the required terms

i₁ = - 4- 6 = -10
i₄ = -4 -6*4 = - 28
i₁₅ = -4 -6*15 = -94

Getting the sum

S₄ = 1/2*4*(-10 - 28) = -76
S₁₅ = 1/2*15*(-10 - 94) = -780
S₅₋₁₅ = S₁₅ - S₄ = -780 - (-76) = - 704

An inequality is shown: −np − 4 ≤ 2(c − 3) Which of the following solves for n?

sesenic [268]

Answer:

$\huge\boxed{n\leq\dfrac{2-2c}{p}\ \text{for}\ p0}$

Step-by-step explanation:

$-np-4\leq2(c-3)\qquad\text{use the distributive property}\\\\-np-4\leq2c-6\qquad\text{add 4 to both sides}\\\\-np\leq2c-2\qquad\text{change the signs}\\\\np\geq2-2c\qquad\text{divide both sides by}\ p\neq0\\\\\text{If}\ p0 ,\ \text{then}\\\boxed{n\geq\dfrac{2-2c}{p}}$
