The total cost for a car with 30 miles is $20.00.

First, do 0.5 × 30 because you need to find out how much it will cost. This will give you 15. From there, add the flat rate. 15 + 5 = 20, so it will cost $20.00.

Answer:

Question 1

<u>Given</u>

  • SP = 144
  • P = 20%
  • CP = x

<u>Use formula and solve for x:</u>

  • SP = CP + P
  • 144 = x + (20% of x)
  • 144 = x + 0.2x
  • 144 = 1.2x
  • x = 144/1.2
  • x = 120

Cost price is N 120

Question 2

<u>Given</u>

  • SP = 1000
  • P = -20% (negative because of loss)
  • CP = x

<u>Use formula and solve for x:</u>

  • SP = CP + P
  • 10000 = x - (20% of x)
  • 10000 = x - 0.2x
  • 10000 = 0.8x
  • x = 10000/0.8
  • x = 12500

Cost is N 12500

Which statements accurately describe the function f(x) = 3(16) superscript three-fourths x? select three options.
sineoko [7]

Range for the given Exponential function f(x) = 3(16)^{{\frac{3}{4}x} is f(x) > 0.

the correction option is a). f(x) > 0

The function given in, the question is exponential function is given by
f(x) = 3(16)^{{\frac{3}{4}x}  Which is an exponential function. The domain of the  give function is (-∞, ∞).

<h3 /><h3>what is exponential function?</h3>

The function which is in format f(x) =  a^{x} where, a is constant and x is variable,  the domain of this exponential function  lies   (-∞, ∞).  

the Question seems to be incomplete. And options could be
a) f(x) > 0              c) f(x) ≤ 0
b) f(x) < 0              d) f(x) ≥ 0

Simplification of the given equation
f(x) = 3(16)^{{\frac{3}{4}x}      
f(x) = 3(2^4)^{{\frac{3}{4}x}
f(x) = 3(8)^{x}

clearly, the range of the exponential function is f(x) > 0.
