Answer:
Neither
Step-by-step explanation:
If the sequence was geometric, each term would be multiplied by the same multiplier to get to the next one. We can check if the multiplier is the same by taking a term and dividing it by the term before it. For example,
-4/3.5=-1.14285714
-7.5/-4=1.87500
The multiplier between the terms aren't the same so it's not geometric.
For arithmetic, the distances between each term would be the same, and we can take the same idea from the geometric sequence, but use subtraction instead of division
-4-3,5=-7.5
-7.5-(-4)=-3.5
Again, the distances aren't the same, so it's not arithmetic.
Answer:
12
Step-by-step explanation:
since the function is -2x+8 and you have been told to find f(-1.8) you have to replace -1.8 were there's x in the function.
f(x)=-2x+8
f(-1.8)=-2x+8
=-2(-1.8)+8
=3.6+8
=11.6 round off to 12

Answer:
-23
Step-by-step explanation:
A quadratic equation is given to us and we are interested in finding the discriminant of the quadratic equation . As we know that ,
If the quadratic equation is in Standard form ,
The discriminant is ,
The given quadratic equation is ,
On comparing it with the Standard form , we have ,
So that ,
Also note that if D < 0 , then the roots are complex conjugates .
<h3>Hence the discriminant is (-23).</h3>
