Answer: -54
Step-by-step explanation:
The question is the first term of a geometric sequence is −2 and the common ratio is 3. The formula for finding the nth term of a geometric sequence is: ar^n-1
where,
a = first term = -2
r = common ratio = 3
n = number of terms = 4
The solution has been attached. The answer is -54
A.0 I think ................
The formula for this is
![A= \frac{1}{2} ( b_{1} + b_{2} )h](https://tex.z-dn.net/?f=A%3D%20%5Cfrac%7B1%7D%7B2%7D%20%28%20b_%7B1%7D%20%2B%20b_%7B2%7D%20%29h)
. Filling in accordingly,
![36= \frac{1}{2}(x+2x)(4)](https://tex.z-dn.net/?f=36%3D%20%5Cfrac%7B1%7D%7B2%7D%28x%2B2x%29%284%29%20)
. This simplifies to
![36= \frac{1}{2}(3x)(4)](https://tex.z-dn.net/?f=36%3D%20%5Cfrac%7B1%7D%7B2%7D%283x%29%284%29%20)
and 36=6x. Therefore, x = 6 so the bases are 6 and 12.
Answer:
The place value to which the number is rounded is unit place.
Step-by-step explanation:
Here, the number 3.695 is rounded to the number 4 and we have to name the place value to which the number is rounded.
Here, the place value to which the number is rounded is unit place.
And the name of the rounding is the rounding to the nearest whole number i.e. there will be no fractional part in the rounded number.
Another example is the number 0.917 is rounded to the nearest whole number to give 1. (Answer)
