Answer:
d
Step-by-step explanation:
A(n) = 1 - 0.1(n-1)
A(1) = 1- 0.1*(1-1) = 1 - 0.1*0 = 1
A(2) = 1- 0.1*(2-1) = 1 - 0.1*1 = 1- 0.1 = 0.9
A(3) = 1 - 0.1(3-1) = 1 - 0.1*2 = 1-0.2=0.8
Method:
A(1)=1
D = A(2)-A(1) = 0.9 - 1 = -0.1
A(n) = A(1)+(n-1)*d = 1 + (n-1)*(-0.1)
= 1 - 0.1(n -1)
Given function is

Now question says to find the graph that shows the axis of symmetry for the given function.
Graph is missing but I can help you to find the correct graph.
Given equation is in the vertex form whose formula is given by

Comparing given function with above formula, we get:
a=1, h=2 and k=1.
For the vertex formula
, we know that axis of symetry is given by equation:
x=h
So for the given function, axis of symmetry will be x=2
Graph of x=2 will be a vertical line crossing x-axis at x=2
So you just need to find the graph from given choices which contains a vertical line crossing x-axis at x=2.
Triangle ABC is isosceles (even tho' it doesn't look so).
m<BDE = m<BED because of that.
Thus, 66 degrees + 2 m<BDE = 180 degrees, and
2 m<BDE = 114 degrees. Thus, m<BDE = 57 degrees.
Answer:2 20%
Step-by-step explanation: you can use it twice
Answer:x = 12
because RHMO is a rhombus => MH⊥RO
=> m∠3 = 90°
⇒ 8x - 6 = 90°
⇔ 8x = 96
⇔ x = 96/8 = 12
