Answer:
(3x-2)(2x+5)
or
(2x+5)(3x-2) by commutative property
Step-by-step explanation:
Let's try factoring by grouping.
I'm going to group the first two terms together and the second two terms together.
Now I'm going to factor what I can from each pair:
Now if you look at the terms 2x(3x-2) and 5(3x-2) you should see they have a common factor of (3x-2) so we can factor that out now.
(3x-2)(2x+5)
Factoring by grouping was a successful here.
Answer:
4a = no. 300 divided by 25 = 12
4b = yes. 333.3 divided by 11 = 30.3
4c = yes. 1,440 divided by 32 = 45
4d = no. 1,725 divided by 25 = 69
Answer:
Explicit formula is .
Recursive formula is
Step-by-step explanation:
Step 1
In this step we first find the explicit formula for the height of the ball.To find the explicit formula we use the fact that the bounces form a geometric sequence. A geometric sequence has the general formula , In this case the first term , the common ratio since the ball bounces back to 0.85 of it's previous height.
We can write the explicit formula as,
Step 2
In this step we find the recursive formula for the height of the ball after each bounce. Since the ball bounces to 0.85 percent of it's previous height, we know that to get the next term in the sequence, we have to multiply the previous term by the common ratio. The general fomula for a geometric sequene is
With the parameters given in this problem, we write the general term of the sequence as ,
Here’s an easy tip.
Always know that the angles next to each other, for example,AB, DC, AD& BC always equal to 180 degrees when added together.
So, we know that angle A plus angle B is 180.
Lets set it up.
2x+1+148=180
Combine like terms.
2x+ 149= 180
Subtract 149 from each side.
2x= 31
X= 15.5 degrees
