How to get the sum of the first 8 terms?</h3>
In an arithmetic sequence, the difference between any two consecutive terms is a constant.
Here we know that:
There are 7 times the common difference between these two values, so if d is the common difference:
Then the sum of the first 8 terms is given by:
So we conclude that the sum of the first 8 terms of the arithmetic sequence is 17/5.

Answer:
Step-by-step explanation:
Given
per hour for 40 hours, weekly
per hour over 40 hours, weekly
Required
Determine f(x)
From the question, we have that
x represents hours worked
Earnings in 40 hours is: 40 * 10 = $400
Hours over 40 will be: x - 40
So, earnings during this time will be: (x - 40) * 15
Total earnings is:
Answer:
We also know that If two angles are complementary then their sum is equal to 90°. So, two angles ∠1 & ∠2 are complementary.
Step-by-step explanation:
As BA is perpendicular to BC. So, angle ∠ABC is 90°.
We also know that If two angles are complementary then their sum is equal to 90°. As ∠ABC is the sum of the ∠1 & ∠2. In other words, ∠1 & ∠2 are complementary. So, two angles ∠1 & ∠2 are complementary.
Lets prove this.
Given: BA ⊥ BC
Prove: ∠1 & ∠2 are complementary.
Statement Reasons
1. ∠1 & ∠2 are complementary 1. Given
2. ∠1 + ∠2 = 90° 2. Def. of complementary angles
Answer:
it should be pretty close but not all the time 100% accurate depending on how well it is done. if you're talking about it in a lab sense, there's sometimes human error, or the equipment you're using isn't always 100% accurate either which leads to a slight difference. As long as everything is done correctly it should be relatively the same
