Consider the arithmetic sequence below.

Mathematics
2 answers:
AleksandrR [38]3 years ago
6 0
The given sequence is:

<span>-9, -2, 5, 12, . . .

So, the first term of the sequence is -9. i.e. f(1) = -9

Common difference of an arithmetic sequence is the difference of any two consecutives terms.

So common difference = -2 - (-9) = -2 + 9 = 7

Therefore, Fourth option is the correct answer.</span>

F(1) is the first term of the arithmetic sequence, then f(1)=-9

Common difference: 7
-2-(-9)=-2+9=7
5-(-2)=5+2=7
12-5=7

Answer: Fourth option
f(1)=-9
Common difference: 7

Find the roots of the polynomial equation.<br><br> 2x3 + 2x2 – 19x + 20 = 0
d1i1m1o1n [39]
First, find any zero of the polynomial. Since you didn't ask for work, I'll assume it's okay if I use my calculator. Your given polynomial has only one real root which is x=-4.

Now we use the rule that x-a divides the polynomial where a is a zero of said polynomial.

So x+4 divides 2x^3+2x^2-19x+20. 
<span>(2x^3+2x^2-19x+20) / (x+4 equals 2x^2-6x+5).
 
If we factor out a two, we can use the quadratic formula.

2(x^2-3x+2.5) so we have x = (-(-3)+/-(9-4*1*2.5)^(1/2))/2*1)=(3+i)... or (3-i)/2 Where i is the square root of negative one. final answer:
2x^3+2x^2-19x+20=0
 
then x=-4, (3+i)/2, or (3-i)/2
</span>we have two imaginary number.

Write a proportion and identify the means and extremes. will do branilyest
Yakvenalex [24]
Hi,

One example of proportion is 1:2=6:12 , with 1 and 12 being the extremes and 2 and 6 the means. In general, a proportion is an equality of two ratios, a:b=c:d, and a and d are called extremes while b and c are called means.

Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know.
