Answer:
C a1= -2
an = an-1 +3
Step-by-step explanation:
an = -2+ (n-1)3
What is the first term? Let n=1
a1 = -2 + 0*3
a1 = -2
The difference between the terms is +3 (coefficient on (n-1))
The second term is the first term +3
The third term is the second term plus 3
The next term is the previous term +3
so an = an-1+ 3
Answer:
4 pitchers
Step-by-step explanation:
we know that
The volume of a cylinder is equal to
![V=\pi r^{2}h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E%7B2%7Dh)
step 1
Find the volume of the cylinder with height 9 inches and radius r
substitute the given values
![V_1=\pi r^{2}(9)](https://tex.z-dn.net/?f=V_1%3D%5Cpi%20r%5E%7B2%7D%289%29)
![V_1=9\pi r^{2}\ in^3](https://tex.z-dn.net/?f=V_1%3D9%5Cpi%20r%5E%7B2%7D%5C%20in%5E3)
step 2
Find the volume of the cylinder with height 9 inches and radius 2r
substitute the given values
![V_2=\pi (2r)^{2}(9)](https://tex.z-dn.net/?f=V_2%3D%5Cpi%20%282r%29%5E%7B2%7D%289%29)
![V_2=36\pi r^{2}\ in^3](https://tex.z-dn.net/?f=V_2%3D36%5Cpi%20r%5E%7B2%7D%5C%20in%5E3)
step 3
we know that
The volume of the cylinder 1 can fill a certain pitcher,
so
The volume of the pitcher is the same that the volume of cylinder 1
therefore
the number of pitchers that can be filled by the second cylinder is equal to divide the volume of the second cylinder by the volume of the first cylinder
![\frac{36\pi r^{2}}{9\pi r^{2}}=4\ pitchers](https://tex.z-dn.net/?f=%5Cfrac%7B36%5Cpi%20r%5E%7B2%7D%7D%7B9%5Cpi%20r%5E%7B2%7D%7D%3D4%5C%20pitchers)

Answer: x + y = 2</h3>
====================================================
Work Shown:
y - 6 = -(x + 4)
y - 6 = -x - 4
y = -x - 4 + 6 ..... adding 6 to both sides
y = -x + 2
y + x = 2 .... adding x to both sides
x + y = 2
The equation is in standard form Ax+By = C, with A = 1, B = 1, and C = 2.
I’m assuming the 2’s are supposed to be exponents so you’re gonna to combine 7m^2 and 4m^2 to get 11m^2 so you’re answer would be
11m2+3m
You dint know the value of M so you can’t solve it, especially because there’s no equal sign with a number or expression/equation after it.
Example- 1/3 or 1/5, which is larger? If you divide 1 by 3 the answer is 0.33 If you divide 1 by 5 it's 0.2. Since 0.33(1/3) is larger that would be the answer.
sorry if I make this confusing.
basically divide the top by the bottom to see which is larger. Then compare the fractions.
