Answer:

250

Explanation:

The general term of a geometric sequence has the form:

an= a⋅r^n−1

where a is the initial term and r the common ratio.

In the example: a 1 = 1250 and 3 = 50

So: r^2 = ar^2/ar^0 = a^3/a^1 = 50/1250=1/25=1/5^2

Hence: r = ± 1/5

Then: a^2= a⋅ r ^2−1 = 1250⋅(±1/5)= ±250

Multiply 5( 4n -5) tell me how

rewona [7]

Distribute

5 × 4n + 5 × -5

Simplify 5 × 4n to 20n

20n + 5 × -5

Simplify 5 × -5 to -25

20n - 25

In how many years will $7000 yield an interest of $4620 at 22% simple interest?

meriva

Answer:

3 Years

Step-by-step explanation:

7000*22% = 1540

4620/1540 = 3

1540 = the yearly interest

so it will take 3 years of $1540 of interest to get $4620.

Normally you would also have to take into account the interest plus the base varible but since it specifically says 7000 it makes it a simple problem.

hope this helped

What is the equation in slope intercept form of the perpendicular bisector of the given line segment?

andreev551 [17]

Answer:

y = -4x - 6

Step-by-step explanation:

The equation of a line in point-slope form.

$y - y_1 = m(x - x_1)$

is the equation of the line containing point (x1, y1) and having slope, m.

The given point of the perpendicular bisector is (-1, -2), so in this case, x1 = -1, and y1 = -2.

We need the slope of the perpendicular bisector. First we find the slope of the segment. We start at point (-5, -3). We go up 1 unit and 4 units to the right, and we are at another point on the segment. Since slope = rise/run, the slope of the segment is 1/4. The slopes of perpendicular lines are negative reciprocals, so the slope of the perpendicular bisector is the negative reciprocal of 1/4, so for the perpendicular bisector, m = -4.

Now we use the equation above and our values.

$y - y_1 = m(x - x_1)$

$y - (-2) = -4(x - (-1))$

$y + 2 = -4(x + 1)$

$y + 2 = -4x - 4$

$y = -4x - 6$
