Use inductive reasoning to find the next term in the sequence 0, 1, 1, 2, 3, 5, 8 …<br>Answer is 13
expeople1 [14]

Answer:

13

Step-by-step explanation:

Look carefully:  you'll see that each new term is the sum of the previous two terms.  The 3rd term is 0 + 1, or 1.  The 4th term is 1 + 1, or 2.  The 8th term is the sum of 5 and 8, or 13.

Can someone help me with these functions
ryzh [129]

Answer:

Function 1:

The starting point is (0,0.5)

As x increases, y increases

Function 2:

The starting point is (0,3)

As x increases, y decreases

Step-by-step explanation:

In order to find the starting point, we need to plug in x=0.

y=0.5+3(0)\\\\y=0.5

y=3(0.5)^0\\\\y=3(1)\\\\y=3

As we plug in increasing numbers into function#1, the y-value increases

As we plug in increasing numbers into function #2, the y-value is decreasing

What is the 12th term of the sequence 3,6,12,24....
Sati [7]
a_{0}=3

r=common ratio: 12/6=2; 6/3=2

r=2, a_{n}=2^{n-1}*3

plug in 12 for n:

a_{12}=2^{12-1}*3

a_{12}=2^{11}*3

a_{12}=2048*3

a_{12}=6144

The twelfth term in the sequence is 6144

How do you solve surface area
LekaFEV [45]
For squares and rectangles, it's easy: multiply the length of one side by the other.

For equilateral and isosceles triangles, measure the height (distance from one pointy tip to the point exactly halfway between the other two pointy tips) and multiply by half of the width of the base.  Scalene triangles are more complicated and vary depending on their exact measurements.  However, you can often divide them into several smaller isosceles triangles that can be easily calculated for.

For cylinders, find the area of one circle (use the equation A = \pi r^{2}) and multiply the answer by 2.  Call this number A.  Then, find the circumference of one of the circles.  Call this number C.  Then, measure the length of the cylinder.  Call this number L.  Multiply L and C together, then add A to the product.  That's the surface area of the cylinder.

For spheres, use the equation A = 4 \pi r^{2}, where A represents the surface area, \pi is approximately equal to 3.14, and r represents the radius, which is always exactly half of the diameter. 

Most other shapes, whether 3-dimensional or 2-dimensional, can be calculated by simply adding together the areas of their component parts.  An octagon can be divided into 8 isosceles triangles, which if you're given the right information are easy to calculate for (height times base divided by 2).  Once you find the area of one piece of the octagon, multiply by 8 (the number of sides).  This works for any regular polygon of n sides.
 
If you're being given irregular shapes, just divide them into many smaller, simpler ones that you already know how to calculate for.  Once you've determine the area of each of the component parts, add everything together to find the total area of the whole.
