sum of sequence Find the sum of 46 + 42 + 38 + ... + (-446) + (-450) is -25,250
<u>Step-by-step explanation:</u>
We need to find sum of sequence : 46 + 42 + 38 + ... + (-446) + (-450)
Given sequence is an AP with following parameters as :
So , Let's calculate how many terms are there as :
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Sum of an AP is :
⇒ 
⇒ 
⇒ 
⇒ 
Therefore , sum of sequence Find the sum of 46 + 42 + 38 + ... + (-446) + (-450) is -25,250
Answer:
-2.2
Step-by-step explanation:
By using the equation 5*(4+x)=9, when you isolate x you get -2.2.

Answer: $4.52
Step-by-step explanation:
From the question, sales tax rate is $8.25 per $100, this means that for every $100 item sold, $8.25 will be paid as sales tax.
Sales tax for 54.80 = x
Step 2: write the equation as;
8.25 = $100
Sales tax for $1 item will be (divide both sides by 100
$8. 25/ 100 = $0.0825
Step 3: determine the sales tax on $1 item, that is if sales tax $1 item = $0.0825
Sales tax for $54.80 item will be 0.0825 x 54.80
= $4.52
15m ^3 - 26m^2 +11m - 4 is the result of the product.
(5m^2 -2m +1)(3m-4)
On opening the bracket, we multiply the terms,
= 15m^3 -6m^2 +3m -20m^2+8m -4
= 15m ^3 - 26m^2 +11m - 4
This is the result of the product
When we mutiply the two equations.
