using distance formula what is the distance point between (-8,4) and (-4,-1) round to nearest tenth ​
RideAnS [48]

Answer:

6.4 units

Step-by-step explanation:

Distance² = (change in y)² + (change in x)²

Distance² = (4 - -1)² + (-8 - -4)²

Distance² = 25 + 16 = 41

Distance = \sqrt{41} = 6.403124237

The distance is 6.4 units (rounded off to nearest tenth)

Consider this system of linear equations: y=4/5x-3 y=4/5×+1 a. Without graphing, determine how many solutions you would expect t
pychu [463]

The solution of a system of linear equations is the point where the two lines meet. Note that for the given equations, both lines have the same slope (4/5). If two lines have the same slope, it means that those lines are parallel. Parallel lines do not meet at any point, they stay parallel to the infinite.

Therefore, since this two lines are parallel, they don't meet and the system has no solution.

Which of the following is a geometric sequence?
anastassius [24]

The key thing to look for to determine whether a sequence is geometric is to see whether the ratio between consecutive terms - the number I would multiply one term by to get the next - is constant.

By inspection, we see that the fourth answer choice satisfies that, as \frac{81}{27}=\frac{27}{9}=\frac{9}{3}=\frac{3}{1}=3. Why not the first? We have 2=\frac{12}{6}\ne\frac{6}{2}=3.

The third choice is not a geometric sequence, but rather an arithmetic sequence, where the difference between consecutive terms is constant. Just to make sure that it isn't geometric, we compute \frac{14}{9}\ne\frac{9}{4}.

The second sequence is not geometric (although it does eventually converge to 1, but not its corresponding series), as \frac{4}{3}=\frac{2/3}{1/2}\ne\frac{3/4}{2/3}=\frac{9}{8}.
