Write a formula to describe the sequence
Dominik [7]

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)

Which graph shows the axis of symmetry for the function f(x) = (x – 2)2 + 1?
OleMash [197]

Given function is

f(x)=(x-2)^2+1

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

f(x)=a(x-h)^2+k

Comparing given function with above formula, we get:

a=1, h=2 and k=1.

For the vertex formula f(x)=a(x-h)^2+k, 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.

Given that RHMO is a rhombus, find x, given that m ∠ 3 = 8x - 6
alexandr1967 [171]

Answer:x = 12

because  RHMO is a rhombus => MH⊥RO

=> m∠3 = 90°

⇒ 8x - 6 = 90°

⇔ 8x = 96

⇔ x = 96/8 = 12
