Place the following in increasing order: 3/5 70% 0.8 11/20 65% 0.09. How would you explain your process to someone else?

1 answer:

5 0

I converted all to decimal

x%=x/100
so

3/5=6/10=0.60
70%=70/100=7/10=0.70
0.8=0.80
11/20=5.5/10=0.55
65%=65/100=6.5/10=0.65
0.09=0.09

so increasing
smallest to largest
0.09, 0.55, 0.60, 0.65, 0.70, 0.80
or
0.09, 11/20, 3/5, 65%, 70%, 0.8

The sum of the first three terms of a sequence is 6 and the fourth term is 16

Sati [7]

Answer:

a₁ = -5, d = 7, a₂ = 2, a₃ = 9, a₄ = 16

equation of sequence: $\boxed{\bold{a_n=7n-12}}$

Step-by-step explanation:

a₁ + a₂ + a₃ = 6

a₁ + a₁ + d + a₁ + 2d = 6

3a₁ + 3d = 6

a₁ + d= 2 ⇒ a₁ = 2 - d

a₄ = 16

a₁ + 3d = 16

2 - r + 3d = 16

2d = 14

d = 7

a₁ = 2-7 = -5

a₁ = -5, d = 7 ⇒ a₂ = -5+7 = 2, a₃ = 2+7 = 9, a₄ = 9+7 = 16

equation of arithmetic sequence:

$a_n=a_1+d(n-1)\\\\a_n=-5+7(n-1)\\\\\underline{a_n=7n-12}$

What is the inverse of the function f(x) = 2x - 10?

Oxana [17]

Answer:

h(x) = 1/2x + 5

Step-by-step explanation:

Switch the positions of the x and y (f(x)) and solve for y (f(x)).

f(x) = 2x - 10

x = 2y - 10

x + 10 = 2y

(x + 10)/2 = y

1/2x + 5 = y
