Answer:
if the expression is 2x^3 then answer is 54
Step-by-step explanation:
2x^3
substitute in x=3
2* (3)^3
= 2*3*3*3
= 2*27
= 54
please give thanks, hit that heart button :) good luck
Answer:
give branliest pls
Step-by-step explanation:
The answer for the question shown above is the second one, which is: The domain is all real numbers. The range is all real numbers greater than zero.
The explanation is shown below:
You have the following function given in the problem above f(x)= (1/5)^x. As you can see, it is a exponential function. By definition, the domain of the exponential functions is all the real numbers anf their range is all real numbers greater that zero.
Answer:
Option B. 5.5 ft²
Step-by-step explanation:
Perimeter of the square piece of land = length of fence required
4(length of a side of the square) = 24 ft
Length of a side = 6 ft
Area of the square land = (Side)²
= 6²
= 36 square ft
Area of the side walk = Area of the square - [Area of two triangles separated by the sidewalk]
= 36 - [1/2 (Area Of The Sqaure) + 1/2 (Base) (Height) ]
= 36 - [36/2 + 1/2 (6 - 1) (6 - 1)]
= 36 - (18 + 12.5)
= 36 - 30.5
= 5.5 ft²
Therefore, Option B. is the correct answer.
<h3>
Answer: $1,143.60</h3>
Work Shown:
A = P*(1+r/n)^(n*t)
A = 800*(1+0.18/12)^(12*2)
A = 1,143.60224954321
A = 1,143.60
Notes:
- P = 800 is the principal. It is the amount loaned to Jake.
- r = 0.18 is the decimal form of the 18% interest rate
- n = 12 because we're compounding monthly, i.e. 12 times a year
- t = 2 = number of years
