Answer:
B
Step-by-step explanation:
eliminating systematic measurement errors caused by errors in the measuring instrument used to compare the quantity being measured with a standard.
The elimination method is the process of solving the system of equations, by cancelling unknowns in the system. This makes more simple to solve and easy to solve for the resting unknowns.
Equation solving. A solution is an assignment of expressions to the unknown variables that makes the equality in the equation true. In other words, a solution is an expression or a collection of expressions (one for each unknown) such that, when substituted for the unknowns, the equation becomes an identity .
<span>3,−6,12,−24,...</span>
You can rewrite this as:
<span><span><span>(−1)</span>n</span>3⋅<span>(1,2,4,8,...)</span></span>
If we focus on <span>1,2,4,8...</span>
<span><span>a<span>n+1</span></span>=2<span>an</span></span>
with <span><span>a0</span>=1</span>.
This can be written out as a nice sum:
<span><span><span>N∑</span><span>n=0</span></span><span>2n</span>=<span>20</span>+<span>21</span>+<span>22</span>+<span>23</span>+...</span>
<span>=1+2+4+8+...</span>
Thus, now we can recombine everything to get:
<span>3<span><span>N∑</span><span>n=0</span></span><span><span>(−1)</span>n</span><span>2<span>n
</span></span></span>

Step-by-step explanation:
2x + 9 = 15
you move + 9 to the other side of the equation, you will get:
2x = 15 - 9
2x = 6
So, x = 3
Answer:
I am pretty sure 1=constant independednt, 2 is inconsistent and three is constant dependent
Step-by-step explanation:
I am not positive tho..
Answer: 196πcm²
Given
Diameter = 14
Radius = d/2
= 14/2
= 7
Surface area = 4πr²
Take π = 22/7
= 4×22/7×7×7
= 616 cm²
