256 being rounded would become 260 and 321 would become 320 so adding up the estimates the would be 580 (real answer is 577)
Answer:
Total annual premium = $1770.10
Step-by-step explanation:
Given the information in the problem, looking at the different categories of each level of insurance and the corresponding premium will give you the amounts for each part. To find the total annual premium, you need to find the sum of all the parts and then multiply this by the rating factor for his gender and age group.
Since he is purchasing 100/300/100 liability insurance, you need to first look at the 'Liability Insurance' table and locate the 100/300 option under 'Bodily Injury'. This premium is $450. Also, he is purchasing an additional 100 for Property damage which is an added premium of $375.
Next, he is getting collision insurance with a $100 deductible. This is the second column in the second table and has a premium of $215. He also wants comprehensive insurance with a $250 deductible which has a premium of $102.
Since he is a 26-year-old male, his rating is 1.55, so we will need to multiply the sum of his premiums by this number:
(450 + 375 + 215 + 102)1.55 = $1770.10
Answer:
C
Step-by-step explanation:
An approximation of an integral is given by:

First, find Δx. Our a = 2 and b = 8:

The left endpoint is modeled with:

And the right endpoint is modeled with:

Since we are using a Left Riemann Sum, we will use the first equation.
Our function is:

Therefore:

By substitution:

Putting it all together:

Thus, our answer is C.
*Note: Not sure why they placed the exponent outside the cosine. Perhaps it was a typo. But C will most likely be the correct answer regardless.
Start with the point-slope form:
.
Then you substitue in the slope and coordinates from the point:

You don't do a lot of clean up to the form, with the exception of turning "minus negative 7" into "plus 7".

Thar be yer answer!
I dont know the awnser sorry
