Answer: -3/11, -0.29, -2/7
Step-by-step explanation: 3 divided by 11 is 0.27 rounded: -0.27
2 divided by 7 is 0.29 rounded so you have to round to the thousandths so it would be 0.296: -0.296
Answer:
About 3.18
Step-by-step explanation:
If u do the opposite of multiplication u get x
2b+25c+12 is a simplified version of that
In order to find the answer for this problem, there are two ways to do that.
Analyze the problem. The paint costs $450 at present. This doubles after 5 years which makes it $900. Another 5 years, which is 10 years in total, it will be $1800.
Next, solve it using this equation:
<span>450×<span>2^<span>t/5 where t is the number of years which is 10.
</span></span></span><span>450×<span>2^10/<span>5
</span></span></span><span>450×<span>2^2
450 x 4 = $1800.
Still the answer is the same. So the answer would be the third option. Hope this answer helps.</span></span>
Answer:
B. quadratic
Step-by-step explanation:
The numbers of dots are 1, 5, 12, 22, 35.
These values do not have a common ratio, so the sequence is not exponential.
First differences are 4, 7, 10, 13. These values are not constant, so the sequence is not linear.
The differences are not decreasing, so the sequence is not logarithmic.
Second differences are 3, 3, 3. These values <em>are</em> constant, so the sequence is described by a 2nd-degree polynomial. The pattern is quadratic.

The pattern can be described by ...
f(x) = (3x -1)x/2
