Answer:
1) 48p^2+4p-4
2)40b^2-45b+5
3)3p^2-6p+3
4)3v^2-6v+3
5)40x^2+28x+24
6)3x^2+15x+12
Step-by-step explanation:
Answer:
Terms:
<em>5, 2x, 4, 3x</em>
Coefficients:
<em>2 in 2x, and 3 in 3x</em>
Constants:
<em>5 and 4</em>
Factors:
<em>5, 2x, and 4</em>
Step-by-step explanation:
For terms, all of them are terms because they are all in the expression.
For coefficients, coefficients are ones that have a variable (think of it as a <em>copilot</em> kind of thing).
For factors, factors are terms that are multiplied together together to get a <em>product</em> (the answer).
For constants, these are terms that stand alone, by themselves. They are not attached to variables.
The answer is <em>13x + 20, </em>too, just in case you needed that.
Have a great day and hope this helps!
Answer:
1.5 seconds
Step-by-step explanation:
plug 0 in for y
0=-16t^2+36
then slove for t
-36=-16t^2
-36 / -16 = 9/4
9/4=t^2
square root of 9/4 is 3/2 or 1.5
t=1.5
Answers:
P(A) = 7/12
P(B) = 1/2
=====================================================
Explanation:
To see how I calculated P(A), check out this link to this very similar question

--------------------
Now to calculate P(B)
If a number is divisible by 2, then the number is a multiple of 2.
In other words, the number is even.
Counting through the values in the table, you should find that there are 18 sums that are even (2, 4, 6, 8, 10 and 12). Refer to the dice chart below.
Here's a further breakdown
- 1 copy of "2"
- 3 copies of "4"
- 5 copies of "6"
- 5 copies of "8"
- 3 copies of "10"
- 1 copy of 12
Side note: We have nice symmetry going on.
There are 1+3+5+5+3+1 = 18 values total that are even numbers. The other half are odd numbers of course.
P(B) = 18/36 = (1*18)/(2*18) = 1/2
The x-values are the heartbeat(s) and the y-values are the time(s)
<h3>How to determine the x and y values?</h3>
The variables are given as:
Time(s) and Heartbeat(s)
As a general rule, the action that is being done is the independent variable.
The action here is the heartbeat.
So, the x-values are the heartbeat(s) and the y-values are the time(s)
A possible value of this is;
x = 100, y = 60 seconds
So, the ordered pair is (100,60)
When represented as ratio, we have;
Ratio = 60/100
Simplify
Ratio = 0.6 heartbeat per second
