answer:

-1> x

step-by-step explanation:

–5x – 15 > 10 + 20x

add 5x to each side

–5x+5x – 15 > 10 + 20x+5x

-15 > 10+25x

subtract 10 from each side

-15-10 > 25x

-25 > 25x

divide by 25

-25/25 > 25x/25

-1> x

answer: y = 4*0.5^x

explanation:

first we'll use the point (1,2) to isolate c in terms of 'a'

y = c*a^x

2 = c*a^1 plug in (x,y) = (1,2)

2 = c*a

c = 2/a

the use the last equation mentioned above, along with the second point (2,1) to determine the value of 'a'

y = c*a^x

y = (2/a)*a^x replace c with 2/a

y = 2*a^(-1)*a^x

y = 2a^(-1+x)

1 = 2a^(-1+2) plug in (x,y) = (2,1)

1 = 2a^1

1 = 2a

a = 1/2 = 0.5

this value of 'a' leads to

c = 2/a

c = 2/0.5

c = 4

since a = 0.5 and c = 4, the answer is y = 4*0.5^x

answer:

see explanation

step-by-step explanation:

area of sector = area of circle × fraction of circle

                        = π × 24² ×

                      = π × 576 × = 72π units² ← exact value

area of sector = 72π units² ≈ 226.2 units² ( 1 dec. place )

answer:

2.27 =y

step-by-step explanation:

tan theta = opposite side/adjacent side

tan 18 = y /7

multiply each side by 7

7 * tan 18 = y/7*7

7 tan 18 = y

2.274437874 y

rounding to the hundreds place

2.27 =y
