It has 4 significant figures
Make the y as the subject like y= 3x + 1
the slope was next to the x
so the slope is 3
i am a mathematics teacher. if anything to ask please pm me
Observe that the difference of the sequence is 30. The first term is 12.
Let's use the arithmetic sequence formula
Replacing the given information, we have.
<h2>Hence, the right answer is C because it relates correctly the first term and the difference.</h2>
Answer:
You will need to convert to degrees when you are taking a right-triangle approach to trigonometry. In other words, if you are not utilizing aspects of the unit circle, you should convert to degrees. The opposite would go for radians. When you are taking a unit circle approach, convert degrees to radians.

Step-by-step explanation:
From the given information:
Let assume that the invested amount in the investment paying 8% interest is a
Now, since the total amount invested = $3000.
Then, the amount invested in the investment that will be paying 10% interest can be represented as:
= $(3000-a)
Income earned on $a that is being invested in 8% interest = $a × 8/100 = $0.08a
Income earned from $(3000-a) in the 10% investment is:
= $(3000-a)× 10/100
= $(300 - 0.1a)
Since total income of the two investment = $290;
Then;
0.08a + (300 - 0.1a) = 290
0.08a + 300 - 0.1a = 20-
300 - 0.02a = 290
-0.02a = -10
a = -10/-0.02
x = 500
Thus;
the amount invested in an investment paying 8% interest = $500
the amount invested in an investment paying 10% interest = $(3000 - 500) = $2500
