Answer:

C. 192 1/2 in^2.

Step-by-step explanation:

Split this up anto 1 triangle and one rectangle

Area of the triangle = 1/2 * base * height

Its height = 36 - 25 = 11, and the base = 2 1/4 + 2 1/4 + 5 1/2= 10.

So it's area = 1/2 * 10 * 11 = 55.

Area of rectangle = 25 * 5 1/2 = 137 1/2.

Total area of the arrow = 55 + 137 1/2 = 192 1/2 in^2.

G(x)=−4x+4, find g(3)

I believe your answer is:

$g(3) = -8$

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\boxed{\text{Evaluating the function...}}\\\\g(x)=-4x+4; g(3)\\\\--------------\\\rightarrow g(3)=-4(3)+4\\\\\rightarrow g(3) = -12 + 4\\\\\rightarrow \boxed{g(3)=-8}$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Find the 8th term of the geometric sequence 3, 9, 27, ...

miv72 [106K]

Answer:

8th term- 6,561

Step-by-step explanation:

Each term in the sequence is being multiplied by 3. For example, 3x3=9 and 9x3=27. Now, we need to continue multiplying numbers, so we can list them all here, still starting with 3.

1&2) 3x3=9

3) 9x3=27

4) 27x3=81

5) 81x3=243

6) 243x3=729

7) 729x3=2,187

8) 2,187x3=6,561

The 8th term of the geometric sequence is 6,561.

Hope this helps and have a great day! ^^
