If f(x)f(x) is an exponential function where f(4)=25f(4)=25 and f(11)=19f(11)=19, then find the value of f(18)f(18), to the nearest hundredth

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer

thus, the first answer choice, y = sec x, is the correct one

the height of the surface increases from the center out to the sides of the road

it is c!

answer: i ! the answer is   9000 seconds, also d

hope i
