Which ordered pairs lie on the graph of the exponential function f(x)=4(5)^2x
select each correct answer:
(-1,4/25)
(0,0)
(1,4)
(2,2500)
The ordered pairs [tex]\left(-1, \frac{4}{25}\right)[/tex] and [tex](2,2500)[/tex] lie on the graph of the exponential function.
The quickest approach consists in evaluating the function at each value of [tex]x[/tex] to determine if the resulting value of [tex]y[/tex] coincide with the value given in statement.
x = -1
[tex]f(-1) = 4\cdot 5^{2\cdot (-1)}[/tex]
[tex]f(-1) = \frac{4}{25}[/tex]
The resulting value coincides with the value given in statement.
x = 0
[tex]f(0) = 4\cdot 5^{2\cdot (0)}[/tex]
[tex]f(0) = 4[/tex]
The resulting value does not coincide with the value given in statement.
x = 1
[tex]f(1) = 4\cdot 5^{2\cdot (1)}[/tex]
[tex]f(1) = 100[/tex]
The resulting value does not coincide with the value given in statement.
x = 2
[tex]f(2) = 4\cdot 5^{2\cdot (2)}[/tex]
[tex]f(2) = 2500[/tex]
The resulting value coincides with the value given in statement.

The ordered pairs (-1, 4/25) and (2, 2500) lie on the graph of the exponential function f(x) = 4 × (5)^(2x), while (0, 0) and (1, 4) do not.
To determine which ordered pairs lie on the graph of the exponential function f(x) = 4 × (5)^(2x), we can substitute the given x-values into the function and check if the resulting y-values match the given coordinates.
For the point (-1, 4/25):
f(-1) = 4 × (5)^(2(-1)) = 4 × 1/25 = 4/25
This matches the given coordinate, so (-1, 4/25) is on the graph.
For the point (0, 0):
f(0) = 4 × (5)^(2 × 0) = 4 × 1 = 4
This doesn't match the given coordinate, so (0, 0) is not on the graph.
For the point (1, 4):
f(1) = 4 × (5)^(2 × 1) = 4 × 25 = 100
This doesn't match the given coordinate, so (1, 4) is not on the graph.
For the point (2, 2500):
f(2) = 4 × (5)^(2 × 2) = 4 × 625 = 2500
This matches the given coordinate, so (2, 2500) is on the graph.

Find the take-home percent of the gross pay: net pay $453.10, gross pay$734
50%
16%
162%
62%
Answer:
Option D. 62%
Step-by-step explanation:
Net pay = $453.10
Gross pay = $734.00
We have to find the take-home percent of the gross pay.
We will divide net pay by gross pay and multiply by 100.
Percent of the gross pay = [tex]\frac{453.10}{734}\times 100[/tex]
= 0.617302452 × 100
= 61.73 ≈ 62%
The take-home percent of the gross pay would be 62%.

The currency in Argentina is the Peso. The exchange rate is approximately $3 = 1 Peso. At this rate, how many Pesos would you get if you exchanged $121.10?
The Pesos you would get if you exchanged $121.10 using an exchange rate of $3 = 1 Peso, you can set up a proportion and solve for x.
Explanation:To calculate how many Pesos you would get if you exchanged $121.10 at an exchange rate of $3 = 1 Peso, you can set up a proportion:
$3 / 1 Peso = $121.10 / x Pesos
Cross multiply to solve for x:
$3 * x = $121.10 * 1
x = $363.30
Therefore, you would get 363.30 Pesos if you exchanged $121.10 at the given exchange rate.
