Answer:
x = 216
Step-by-step explanation:
2 + 5 = 32
Subtract 2 from both sides of the equation
i.e. 2 + 5 - 2 = 32 - 2
5 = 30
Take the cube of both sides of the equation
i.e. (5)³ = (30)³
(5)³()³ = (30)³
(5 × 5 × 5)()³ = (30 × 30 ×30)
125x = 27,000
Divide both sides of the equation by the coefficient of x(which is 125)
x = 216
<u>Check</u>
Substituting 216 for x in 2 + 5∛x = 32,
2 + 5 = 32 ( = 6)
2 + (5 × 6) = 32
2 + 30 = 32
∴ x = 216
Hope this helps :))
The answer is: [C]: " f(x) = 0.7(5)ˣ " .
_________________________________________________________
Explanation:
_________________________________________________________
From all the answer choices given;
Answer choice: [C]: " f(x) = 0.7 (5)ˣ " ; is the answer choice with a "positive number"; {which is then multiplied by: [ a "positive whole number" or a "positive number greater than "1"; that is raised to a "positive variable"] .

How I solved this: Further Explanation:
________________________________________________
A positive number multiplied by a {"number less than 1; raised to "x"] would result in increasingly lower values as "x" increases. Same with "raised to "negative x" {refer to "Answer choice [D]" }.
Answer: f(x)=200•(0.85)^x
Step-by-step explanation:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
Depreciation is often modeled as an exponential decay function. Since Jim bought a skateboard for Co=$200, its value will depreciate by r=15% = 0.15 each year since buying it.
Answer:
<em>BC, BD, BQ, CB, CD, CQ, DB, DC, DQ, QB, QC, QD </em>
Step-by-step explanation:
<em>"BC, BD, BQ, CB, CD, CQ, DB, DC, DQ, QB, QC, QD"</em> Are all the possible rays on line c.
Convert each fraction to decimal:-
3/5
3 ÷ 5 = 0.6
7/8
7 ÷ 8 = 0.875
5/6
5 ÷ 6 = <span>0.8333 </span>≈ 0.83
least to greatest:-
0.6 < 0.83 < 0.875
3/5 < 5/6 < 7/8
