How do you find the nth term in a sequence?

1 answer:

3 0

sequences can be expressed in terms of the nth term of the sequence. In this case, the nth term = 2n. To find the 1st term, put n = 1 into the formula, to find the 4th term, replace the n's by 4's: 4th term = 2 × 4 = 8.

A polynomial function is given.

faltersainse [42]

Answer:

Step-by-step explanation:

Look what happens if you do the multiplication of P(x):

P(x) = x^3 - 9x

This is a variation of the basic cubing function y = x^3.

The graph begins in QIII and ends in QI; in other words, if you go left the graph drops; if you go right, the graph rises (without limit, in both cases).

Solve the following inequality. 21<_-3(x - 4) < 30 A. 28<_x < 37 B. -3 <_ x < 6 C. -6 < x <_ -3 D. -10 &

Aloiza [94]

Answer:

Option C $-6$

Step-by-step explanation:

we have

$21\leq -3(x-4)$

The compound inequality can be divided into two inequality

$21\leq -3(x-4)$ -----> inequality A

$-3(x-4)$ ----> inequality B

Solve inequality A

$21\leq -3x+12$

$9\leq -3x$

Divide by -3 both sides

when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

$-3\geq x$

Rewrite

$x\leq -3$

The solution of the inequality A is the interval (-∞,-3]

Solve the inequality B

$-3x+12$

$-3x$

Divide by -3 both sides

when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

$x>-6$

The solution of the inequality B is the interval [-6,∞)

The solution of the compound inequality is

[-6,∞) ∩ (-∞,-3]=(-6,-3]

$-6$

Measure of each side of an equilateral triangle is 12cm. It's area is given by

telo118 [61]

Answer:

Step-by-step explanation:

The area (A) of an equilateral triangle is calculated as

A = $\frac{s^2\sqrt{3} }{4}$ ← s is length of a side

Here s = 12, thus

A = $\frac{12^2\sqrt{3} }{4}$

= $\frac{144\sqrt{3} }{4}$

= 36 $\sqrt{3}$ → D

BRAINLIESTTT!<br>Explain why the parabola has a round curved shape?

dolphi86 [110]

All parabolas have a curved shape when they are graphed.
The parabolic curve is the locus of points where the equation is satisfied, which makes it a Cartesian graph of the quadratic function in the equation.
Now, I do not see a specific picture... but I do know that the whole point in a parabola is for it to have that round look.

Hope this helps!
