find the domain and range of the exponential function h(x) = 125x. explain your findings. as x decreases, does h increase or decrease? explain. as x increases, does h increase or decrease? explain.
We have an exponential growth. The domain is the set of all real numbers and the range is R: (0, ∞).
What can we say about the exponential function?Here we have the exponential function:
[tex]h(x) = 125^x[/tex]
Notice that the base, 125, is larger than 1, which means that we have an exponential growth.
So, as x increases, also does h(x).As x decreases, also does h(x).Now, the domain of any exponential equation is the set of all real numbers.
For the range, as x tends to negative infinity, the function will tend to zero.
And as x tends to infinity, h(x) also tends to infinity.
So the range is R: (0, ∞).

Select the correct answer. Absolute value functions coordinate plane parabola graphs. Parabola passes through points at (minus 2, 0), (minus 1.5, minus 2.5), (0, 5), (1, 0), (1.5, 2.5) and (2, 0) Which of the given functions could this graph represent? A. B. C. D.
The equation of parabola passing through coordinates A (-2,0), B (-1.5,-2.5), C (0,5), D (1, 0), E (1.5, 2.5), and F (2, 0) is y = -2.5(2x+4)², and the graph is attached.
What is a function?Each element of X receives exactly one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and co-domain, respectively.
Given:
The coordinates of the point of parabola A (-2,0), B (-1.5,-2.5), C (0,5), D (1, 0), E (1.5, 2.5), and F (2, 0).
Calculate the equation of parabola by the formula given below,
[tex]y=a(x-h)^2+k[/tex]
Here (h, k) are the coordinates,
Put A (-2,0)
y = a[x- (-2)] ² + 0
y = a(2x + 4)²
Put B (-1.5,-2.5)
y = a[x- (-1.5)]² + (-2.5)
y = a(x + 1.5)² - 2.5
y = 2ax + 3a -2.5
Solve the above equation
a = -2.5
Thus, the equation of the parabola is,
y = -2.5(2x+4)²
Therefore, the equation of parabola passing through coordinates A (-2,0), B (-1.5,-2.5), C (0,5), D (1, 0), E (1.5, 2.5), and F (2, 0) is y = -2.5(2x+4)², and the graph is attached.

A family has two cars. The first car has a fuel efficiency of 20 miles per gallon of gas and the second has a fuel efficiency of 30 miles per gallon of gas. During one particular week, the two cars went a combined total of 1300 miles, for a total gas consumption of 50 gallons. How many gallons were consumed by each of the two cars that week?
20 gallons of gas was consumed by the car that has efficiency of 20 miles per gallon and 30 gallons of gas was consumed by the car that has efficiency of 30 miles per gallon .
How to find the consumption of gallons using equation?The first car has a fuel efficiency of 20 miles per gallon of gas and the second has a fuel efficiency of 30 miles per gallon of gas.
Therefore,
let
x = number of gallons for car that consume 20 miles per gallon of gas
y = number of gallons for car that consume 30 miles per gallon of gas
Hence,
x + y = 50
20x + 30y = 1300
20x + 20y = 1000
20x + 30y = 1300
10y = 300
y = 300 / 10
y = 30
Therefore,
x = 50 - 30
x = 20

The length of one side of a triangle is 2 feet less than three times the length of its second side. The length of the third side is 3/4 of the sum of the lengths of the first two sides. Find the lengths of all three sides if the perimeter of the triangle is 17.5 feet.
Answer:
7 feet, 3 feet, 7.5 feetStep-by-step explanation:
Let the sides be a, b and c.
GivenThe length of one side of a triangle is 2 feet less than three times the length of its second side
a = 3b - 2The length of the third side is 3/4 of the sum of the lengths of the first two sides:
c = (3/4)(a + b)The perimeter of the triangle is 17.5 feet:
a + b + c = 17.5SolutionSubstitute a with b in the second equation:
c = (3/4)(3b - 2 + b) = (3/4)(4b - 2) = (3/4)(4b) - (3/4)(2) = 3b - 1.5Now substitute a and c with b in the third equation and solve for b:
a + b + c = 17.53b - 2 + b + 3b - 1.5 = 17.57b - 3.5 = 17.57b = 17.5 + 3.57b = 21b = 3Find the value of a:
a = 3b - 2 = 3*3 - 2 = 9 - 2 = 7Find the value of c:
c = 3b - 1.5 = 3*3 - 1.5 = 9 - 1.5 = 7.5The sides of the triangle are:
a = 7 feet, b = 3 feet, c = 7.5 feetplease solve for both parts
(a) The differential equation
[tex]y' + \dfrac14 y = 3 + 2 \cos(2x)[/tex]
is linear, so we can use the integrating factor method. We have I.F.
[tex]\mu = \displaystyle \exp\left(\int \frac{dx}4\right) = e^{x/4}[/tex]
so that multiplying both sides by [tex]\mu[/tex] gives
[tex]e^{x/4} y' + \dfrac14 e^{x/4} y = 3e^{x/4} + 2 e^{x/4} \cos(2x)[/tex]
[tex]\left(e^{x/4} y\right)' = 3e^{x/4} + 2 e^{x/4} \cos(2x)[/tex]
Integrate both sides. (Integrate by parts twice on the right side; I'll omit the details.)
[tex]e^{x/4} y = 12 e^{x/4} + \dfrac8{65} e^{x/4} (8\sin(2x) + \cos(2x)) + C[/tex]
Solve for [tex]y[/tex].
[tex]y = 12 + \dfrac8{65} (\sin(2x) + \cos(2x)) + Ce^{-x/4}[/tex]
Given that [tex]y(0)=0[/tex], we find
[tex]0 = 12 + \dfrac8{65} (\sin(0) + \cos(0)) + Ce^0 \implies C = -\dfrac{788}{65}[/tex]
and the particular solution to the initial value problem is
[tex]\boxed{y = 12 + \dfrac8{65} (\sin(2x) + \cos(2x)) - \dfrac{788}{65} e^{-x/4}}[/tex]
As [tex]x[/tex] gets large, the exponential term will converge to 0. We have
[tex]\sin(2x) + \cos(2x) = \sqrt2 \sin\left(2x + \dfrac\pi4\right)[/tex]
which means the trigonometric terms will oscillate between [tex]\pm\sqrt2[/tex]. So overall, the solution will oscillate between [tex]12\pm\sqrt2[/tex] for large [tex]x[/tex].
(b) We want the smallest [tex]x[/tex] such that [tex]y=12[/tex], i.e.
[tex]0 = \dfrac8{65} (\sin(2x) + \cos(2x)) - \dfrac{788}{65} e^{-x/4}[/tex]
[tex]\dfrac{788}{65} e^{-x/4} = \dfrac{8\sqrt2}{65} \sin\left(2x + \dfrac\pi4\right)[/tex]
[tex]\dfrac{197}{\sqrt2} e^{-x/4} = \sin\left(2x + \dfrac\pi4\right)[/tex]
Using a calculator, the smallest solution seems to be around [tex]\boxed{x\approx21.909}[/tex]

The half life of the radioactive Rutherford-265 is;
13.1 hours.
What is the half-life of the radioactive Rutherford-265?It follows from the task content that the given function represents the decay function of the radioactive material. Since half-life corresponds to the point at which only half of the starting material remains, hence we have;
(1/2) = e ^(-0.053t)
By taking the natural log of both sides, we have;
-0.6931 = -0.053t

It takes 3 hours for the cats to catch 27 fish in the pond.
How long did it take them to catch 27 fish in all?Zarko can catch 5 fish per hour.
Manchu can catch 2 fish every 0.5 of an hour, so in an hour, the cat would catch 2 times that, which is 4 fish.
When working together, the cats can catch 4 + 5 = 9 fish per hour
If the cats work for x hours, then they catch 9*x fish.
To get the time that takes them to catch 27 fish we just need to solve the linear equation:
9x = 27
Solving for x:
x = 27/9 = 3
