Answer:
x^2+11x+10
or
(x+1)(x+10) since you can factor x^2+11x+10
Step-by-step explanation:
Let's do synthetic division.
We are dividing by x+2, so -2 will be on the outside. Like this:
-2 | 1 13 32 20
| -2 -22 -20
|___________________________
1 11 10 0
The remainder is 0, so (x+2) is indeed a factor of x^3+13x^2+32x+20.
The other factor we found by doing this is (x^2+11x+10).
You can find more factors by factoring x^2+11x+10.
Two numbers that multiply to be 10 and add to be 11 is 10 and 1 so the factored form of x^2+11x+10 is (x+10)(x+1).
Answer:
The value of x is 0.37037 repeating
Step-by-step explanation: 9/5x=1.8 2/3=0.67 repeating then you do .67 divided by 1.8 and that gives you 0.37037 repeating.
Answer:
75 seconds
Step-by-step explanation:
Here, we want to get her time 6 weeks ago.
We shall have an exponential model to link this all up
The exponential model would look like;
y = I(1 - r)^n
where y is the present time
I is the initial time she started with which we are calculating
r is the rate of change which is 2% = 2/100 = 0.02
n is the week number which is 6 in this case
So we have;
66 = I(1 - 0.02)^6
66 = I(0.98)^6
I = 66/0.8858
I = 74.5 seconds
This is approximately 75 seconds
Her time 6 weeks ago is 75 seconds
Answer:
6
Step-by-step explanation:
add 4 + 5(4)+6(3)+7(2)+10 once you add those divide it by 11 because that is how many data points there are. so the mean (average) is 6
Answer:
21
Step-by-step explanation:
2:7 Ratio
Since he got 6 wrong it 6:?
6/2 = 3
3*7=21
6:21
He got 21 right
