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 .

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 true statement about the graph of [tex]f(x) = \frac{x^2 + 2x + 1}{2x^2 - 10x+12}[/tex]  is (c) its vertical asymptote are x = 3 and x = 2

The function is given as:

[tex]f(x) = \frac{x^2 + 2x + 1}{2x^2 - 10x+12}[/tex]

Set the denominator to 0

2x^2 - 10x + 12 = 0

Divide through by 2

x^2 - 5x + 6 = 0

Expand

x^2 - 2x - 3x + 6 = 0

Factorize

(x - 2)(x - 3) = 0

Solve for x

x = 2 or x = 3

The above represents the vertical asymptote of the graph

It takes 3 hours for the cats to catch 27 fish in the pond.

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

It takes 3 hours for the cats to catch 27 fish in the pond.

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.

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) 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]

Answer:

Step-by-step explanation:

As the length AB increases, the measure of C increases

As the length AB increases, the measure of C increases.

An angle is formed when two lines or rays meet at a single point. The common point is referred to as the vertex. The length of the angle formed when two rays or arms intersect at a common vertex is known as an angle measure in geometry.

Angles and sides in relation to one another:

The biggest side and angle of any triangle are in opposition to one another.

The smallest side and angle in every triangle are on opposing sides.

The middle side and middle angle are always in opposition to one another in triangles.

When we extend vertex A further to the left of vertex B,

we increase the side length of AB.

As the length AB increases, the measure of opposite angle increases.

Let C be the angle opposite to AB.

Therefore, as the length AB increases, the measure of C increases.
