The ball will take 5.4s to attain a height of 213ft

<h3>Functions</h3>

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

In this case, we simply input the value of s = 213 and solve the quadratic equation.

s(t) = -16t² + 126t

213 = -16t² + 126t

-16t² + 126t - 213 = 0

t = 5.4s

Naily [24]

Answer:

$1023.74

Step-by-step explanation:

Joan wants to buy a new TV that costs $1299.99. The store has a discount on the TV for 30% off. The city Joan lives in has a 12.5% sales tax. What will be the total cost of the TV?

Step 1

We find the new price after the discount.

Discount = % Discount × Current price

= 30% × $1299.99

= $389.997

The new discounted price =

$1299.99 - $389.997

= $909.993

Step 2

We calculate the Sales tax

The city Joan lives in has a 12.5% sales tax.

Hence,

The sales tax =

12.5% × $909.993

= 12.5/100 × $909.993

= $113.749125

Step 3

The total cost of the TV is calculated as:

Sales Tax + Discounted price

= $113.749125 + $909.993

= $1023.742125

Approximately = $1023.74

The total cost of the TV = $1023.74
