We have a4 = a1 * q^3;
Then, 16 = a1 * (1/8);
a1 = 128;
<span>The formula for the nth term of a geometric sequence is an = a1 * q^n;
an = 128 * (1/2)^n = (2^7)/(2^n) = 2^(7-n);</span>
Answer:
Area: 28 cm^2 Perimeter=20 cm
Step-by-step explanation:
A= 1/2 x b x h
A= 1/2 x 8 x 7
A= 28cm^2
P=a + b + c
P = 6+8+6
P = 20 cm
Answer:
b

Answer:
Consider the table for y= |x+1| :
x | y
---------
0 1
1 2
2 3
-1 2
-2 3
This would give us the parent function of y=|x| but translated up one unit. It should look like a v starting at (0, 1)
Answer: The answer is BC=6 and EF=3
Step-by-step explanation: because BC =6 and EF=3 which will be 6/3 =2/1. so divide 6 by 3 to get 2 then anything divided by one gives itself 2=2. Then compare 2 and 2.
