Answer:
? = 22y^2
Step-by-step explanation:
Ask yourself, what times 20y will get me 40y^3?
The answer to this would be 2y^2.
When you multiply something to the denominator, you also have to do so to the numerator. Therefore, you are required to multiply 2y^2 to the 11 to get your '?' value.
11 x 2y^2 = 22y^2
Answer:
no
Step-by-step explanation:
You can simplify them both.
3x+12=12 and 3x + 3 =4
make them both so they equal 0
3x=0 and 3x-1=0
no, theyre not equal since when they both equal 0, they are not the same equation
Well, elevation in how high the hill is from sea level, so the higher the mile, the farther away it is from sea level. The one farthest from sea level is Britton and the one closest is Ray.
Answer: Choice B
a_n = 10(1/2)^(n-2) is the nth term
average rate of change = -35/3
=======================================================
Explanation:
Each time x increases by 1, y is cut in half. For instance, going from (2,10) to (3,5) shows this.
If we want to go in reverse, decreasing x by 1 will double the y value. So (1,20) is another point and (0,40) is another. We'll be using (0,40) and (3,5) because we want the average rate of change from x = 0 to x = 3. I'm using x in place of n here.
Use the slope formula to find the slope of the line through (0,40) and (3,5)
m = (y2-y1)/(x2-x1)
m = (5-40)/(3-0)
m = -35/3
The negative slope means the line goes downhill as you read it from left to right. The average rate of change from n = 0 to n = 3 is -35/3
The nth term of this geometric sequence is 20(1/2)^(n-1) since 20 is the first term (corresponds to n = 1) and 1/2 is the common ratio. Your teacher has done a bit of algebraic manipulation to change the n-1 into n-2. This means the 20 has to change to 10 to counterbalance.
In other words, 20(1/2)^(n-1) is equivalent to 10(1/2)^(n-2) when n starts at n = 1.
