3 0

Answer:

19683

Step-by-step explanation:

As the formula of the geometric sequence:

a_{n} =a_{1} *r^{n-1}

In the sequence of 1, 3, 9..., you have a1 = 1 and r = 3. Therefore:

a_{10} =1 *3^{10-1}  = 3^{9} =19683

Hope this helps!

Nearest hundred thousand 700,00 what is the exact number
coldgirl [10]
It`s either 100,000 because there is only four 0`s making it 70,000 or it`s 700,000 and you made a mistake of not typing that last zero in which case the question would be pointless to ask because the answer is in the question.

Find the slope of the line.
Anika [276]

The equation for working out the slope of a linear line is: \frac{y_2 - y_1}{x_2 - x_1}, where x and y are the coordinate pairs.

So just pick two of the purple dots on the graph and fill in the equation.

I'll pick the dot that's (-4, 1) and (4, -7).

Now I just do \frac{7 - 1}{4 - -4}, which is just \frac{3}{4} when simplified.

The length of a rectangle is 8 inches longer than half of its width.The area of the rectangle is 18 square inches.How many inche
SOVA2 [1]

Answer:

The correct answer is 2 inches.

Step-by-step explanation:

Let l inches and w inches be the length and width of a rectangle respectively.

According to the given problem, l - 8 = \frac{w}{2}.

Area of the rectangle is given to be, according to the question, 18 square inches.

Thus l × w = 18

⇒ l × (2l - 16) = 18

⇒ 2 l^{2} - 16l - 18 = 0

⇒  l^{2} - 8l - 9 = 0

⇒ ( l - 9) ( l + 1) = 0

The possible values of l are 9 and -1. As the length cannot be equal to -1, thus the value of the length is 9 inches.

Width of the rectangle is 2 inches.

Find the solution to the inaquality<br> N+35&lt;22
NikAS [45]

Step-by-step explanation:

N + 35 < 22

To find a solution to this inequality, we need to get N to one side of the equation by itself. Since we have N + 35 on the left-hand side of the equation, we can get

N + 35 < 22

N + 35 - 35 < 22 - 35

N < -13
