You mean 3.3? If that is the case then:
an=1.1+1(n-2)
or an=an-1+1
a1= 1.1
Answer: A
Step-by-step explanation:
If you put 0 in for x, then you would be dividing by 0. Dividing by 0 is always undefined.
Answer:
<u>Area = 36.1 sq. units</u>
Step-by-step explanation:
We will use the "included angle area" formula for a triangle to solve this problem.
The formula is:
![A=\frac{1}{2}abSinC](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7DabSinC)
Where
a and b are the two sides given
C is the angle given BETWEEN the two sides
From the problem, we can write:
the two sides are 6 & 17, so that will be "a" and "b" of the formula
the included angle is 135, so that will be "C" of the formula
Substituting, we find the answer:
![A=\frac{1}{2}abSinC\\A=\frac{1}{2}(6)(17)Sin(135)\\A=36.06](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7DabSinC%5C%5CA%3D%5Cfrac%7B1%7D%7B2%7D%286%29%2817%29Sin%28135%29%5C%5CA%3D36.06)
Rounded to 1 decimal place,
<u>Area = 36.1 sq. units</u>
(4,10).
1. There are three ways to solve this: elimination, substitution, graphing.
2. I chose elimination, so I had to get one negative variable and one positive variable of the same value (for example, 18 and -18)
-7x+2y=-8
-16x+9y=26
I chose to get 2y and 9y to equal -18y and 18y.
So, multiply the first equation by -9. Multiply the second by 2.
63x-18y=72
-32x+18y=52
the 18s cross each other out. So you're left with
63x=72
-32x=52. Add them.
31x=124, divide both sides by 31, and you'll get 4.
x=4
Plug your answer for x into one of the equations. Let's use the first one.
-7(4)+2y=-8
-28+2y=-8. add 28 to both sides.
2y=20, divide both sides by 2.
y=10.
This makes your answer (4,10)
2/8 divided by 1/4. Steps: 1. Division in math actually means multiplication. You just have to multiply by the reciprocal of the second fraction (reciprocal= denominator and numerator are switched). 2. Do 2/8 times 4/1. 3. 2 times 4= 8 and 8 times 1= 8
4. Your answer would be 8/8 which equals 1. This is how you divide fractions
