Answer:
Step-by-step explanation:
{0, -8, -16, -24,...} here you add -8 each time so the rule is
![a_{1} = 0, a_{n} = a_{n-1} -8](https://tex.z-dn.net/?f=a_%7B1%7D%20%3D%200%2C%20a_%7Bn%7D%20%3D%20a_%7Bn-1%7D%20-8)
the 71 term is
![a_{71} = 0 + (71 - 1) * (-8) = 70 * (-8) = -560](https://tex.z-dn.net/?f=a_%7B71%7D%20%3D%200%20%2B%20%2871%20-%201%29%20%2A%20%28-8%29%20%3D%2070%20%2A%20%28-8%29%20%3D%20-560)
I disagree with her she will spent more than that because 6×5.29=31.74$ for 6 roses+4×3.59=14.36 4carnations +8×4.79=38.32$for 4 tulips and then 31.74+14.36+38.32=84.42$ all together
Answer:
B = 40° and D = 60°
Step-by-step explanation:
Just subtract the angles you already know from 90° (since perpendicular means right angle, which is 90°).
Answer:
I am 90% sure that the answer is M'N'O' is 90*
Step-by-step explanation:
A line segment MN is shown as M = -1,1 and N= -5,4 this makes a diagonal line across the grid. Another line segment NO is shown with O as ordered pair negative 1, 4. Angle MNO is rotated 90 degrees counterclockwise about the origin to form angle M′N′O′. this is where the angles meet, Rotating the shape (or the angles) does not change the degree of the angle of the shape. I am 99% sure that an 90* angle would be formed. but im just in middle school so what do i know?

Answer: 120</h3>
===================================================
Explanation:
There are 5 choices for the first selection, 4 choices for the second, etc etc until we reach 1 for the last selection. We have the countdown {5,4,3,2,1}. We'll multiply those values together to get our answer.
5*4*3*2*1 = 120
This operation of starting with some integer, counting down and multiplying along the way, is done so very often that it's given a name which is "factorial". The shorthand notation is to use an exclamation mark. So we'd say 5! = 120
