Answer:
(x + 3)² + (y – 4)² = 1
Step-by-step explanation:
(x – h)² + (y – k)² = r².
Where (h, k) is the center of the circle, and r is the radius of the circle.
T_n = 3 * T_(n-1)
Long way (always works!)
T_5 = 3*T_4,
T_4 = 3*T_3
T_3 = 3*T_2
T_2 = 3*T_1
T_5 = 3*3*3*3*T_1 = 81*T_1 = 81*8 = 648!
Short way (sometimes it works!)
T_n = 3^(n-1) * T_1 (this case is a geometric series of ratio-=3)
T_5 = 3^4*8 = 648
I like the coefienti in front of 2nd degree to be positive
times -1
x^2-4x=-x+4
add x to both sides and minus 4 from both sides
x^2-3x-4=0
factor
what 2 numbers multiply to get -4 and add to get -3?
-4 and 1
(x-4)(x+1)=0
set to zero
x-4=0
x=4
x+1=0
x=-1
-1 and 4
C is answer

Step-by-step explanation:
34 ÷ 4 = 8.5
Answer:
option A
Step-by-step explanation:
From the picture, we can see that:
- The height of the vertical cross section is the same as the height of the prism, that is, 4 inches.
- The base of the vertical cross section is the same as the width of the prism, that is, 8 inches.
