Answer: First Option : Sₙ= n/2(a₁ + aₙ)

Step-by-step explanation:

The nth partial sum of an arithmetic sequence or the sum of the first n terms of the arithmetic series can be defined as the sum of a finite number of term in an arithmetic sequence.

It is calculated using the formula:

Sₙ= n/2(a₁ + aₙ)

Where :

a₁ = First term

aₙ = last term

n = number of terms

Elaina buys eggs and potatoes at a store. She pays a total of $25.92. She pays $2.57 for the eggs. She buys 5 bags of potatoes t

aksik [14]

Answer:

Step-by-step explanation:

the total is 25.92 and Elaina buys 2.57 eggs. So, you would have to first subtract 2.57 from 25.92 . Then she buys 5 bags of potatoes for x price.

This means that 23.35 (25.92-2.57) will have to be divided by 5 to get the price of 1 bag of potatoes.

x= 4.67

Samuel order four did from an online music stores. Each dvd cost 9.99$. He has a 20% discount code and sales tax is 6.75%. What

Stells [14]

The pre tax cost of the four DVDs will be:

4 × 9.99 = 39.96

6.75% tax will amount to 6.75/100 × 39.96 →.0675 × 39.96 = 2.697 or 2.70 rounded off.

Cost of DVDs after tax will be 39.96 + 3.70 = 42.66 $

20% discount will be 20/100 × 42.66 →0.2 × 42.66 = 8.53 $

Cost of DVDs with 20% discount will be 42.66 - 8.53 = 34.13

Rounded off to the nearest cent, the total cost of the order is 34 $ and 10 cents.

iris [78.8K]

Answer:

t = 15.42 s

Step-by-step explanation:

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation.

$y=-16x^2+242x+73$

We ned to find the time when the rocket will the ground. For this, y = 0

$-16x^2+242x+73=0$

It is a quadratic equation whose solution is given by :

$x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}$

Here, a = -16, b = 242 and c = 73

$x=\dfrac{-b+ \sqrt{b^2-4ac} }{2a}, x=\dfrac{-b-\sqrt{b^2-4ac} }{2a}\\\\x=\dfrac{-242+ \sqrt{(242)^2-4(-16)(73)} }{2(-16)}, x=\dfrac{-242- \sqrt{(242)^2-4(-16)(73)} }{2(-16)}\\\\=-0.295\ s, 15.42\ s$
