The graphs of the linear equations will intercept at the point (4, 6)

We know that taxy company a charges $4 plus $0.5 per mile, so the cost for x miles is:

A = 4 + 0.5x

While taxy company be charges $5 plus $0.25 per mile, so the cost for x miles will be:

B = 5 + 0.25x

The graphs will intersect at the x value such that the two linear equations are equal:

A  = B

This happens when:

4 + 0.5x = 5 + 0.25x

0.5x - 0.25x = 5 - 4

0.25x = 1

x = 1/0.25 = 4

And the cost is:

B = 5 + 0.25*4 = 6

So the graphs intercept at the point (4, 6)

Using the formula for calculating speed

The formula for Speed is given as [Speed = Distance ÷ Time].

To calculate the time, the speed formula can be molded as:

Time = Distance ÷ Speed].

Given Distance = 336 feet

Given speed = 48 feet per second

Time = Distance ÷ Speed

They reach their location at 9:24 the next morning.

The relative speed is the net speed of two different objects with respect to each other.

If two objects move in the same direction we take the difference between their speeds.

If two objects move in the opposite direction we take the sum of their speeds.

We can utilize the following parameters in our calculation based on the question,

Time = 4 pm

Distance = 64 km

Calculate how long it took the father to ride his horse and the son to walk the first 32 miles.

Time = Distance / (Difference between rates of father and son)

Time = 32 km / (8 km/h - 3 km/h)

Time = 32 km / 5 km/h

Time = 6.4 hours

Determine how long it will take the father to walk the final 32 miles and the son to ride the horse.

Time = Distance / (Difference in Speed)

Time = 32 km / (8 km/h - 4 km/h)

Time = 32 km / 4 km/h

Time = 8 hours

Therefore,

Total time = 6.4 hours + 8 hours + 3 hours break + 4 pm is 9:24 am the next day.

The area of the triangle ABC is 6√6 cm².

Triangle ABC is depicted in the given diagram, where AB = 7 cm, BC = 6 cm, and AC = 5 cm.

Heron's formula, which claims that the area is provided by: for a triangle with sides of lengths a, b, and c, can be used to determine the triangle's area.

(s(s-a)(s-b)(s-c)) = area

where s is the triangle's semi perimeter and is determined by:

s = (a + b + c)/2

Here are the facts:

7 cm for a and 6 cm for b.

c = 5 cm

The semi perimeter is as follows:

s = (7 + 6 + 5)/2 = 9

When we apply Heron's formula, we get:

Area = √(9(9-7)(9-6)(9-5)) = √(9 × 2 × 3 × 4) = √216

When we reduce the square root, we obtain:

= 6√6 cm²

As a result, the triangle ABC has a 6√6 cm² area.

Answer:

Length = 10cm, Width = 9 cm

Step-by-step explanation:

Let's call the amount that both the length and width are increased by "x". So, the new length is 5 + x and the new width is 4 + x.

The original area of the rectangle was 5 * 4 = 20 cm2.

The new area of the rectangle after the increase is (5 + x) * (4 + x) = 20 + 70 + 2x^2.

Expanding the right-hand side, we have 20 + 70 + 2x^2 = 90 + 2x^2.

Equating the two areas, we get:

20 + 70 + 2x^2 = 90 + 2x^2

Subtracting 2x^2 from both sides:

20 + 70 = 90

Subtracting 20 from both sides:

70 = 70

So x^2 = 50 / 2 = 25.

Taking the square root of both sides, we get:

x = 5

So the length of the longer rectangle is 5 + x = 5 + 5 = 10 cm, and the width is 4 + x = 4 + 5 = 9 cm.

Leonard gave the correct value of approximate average rate of change of function.

What is a function?

In mathematics, a function is an expression, rule, or law that specifies the relationship between an independent variable x and a dependent variable y.

The average rate of change of  function means the typical rate at which one quantity is changing in respect to another. A method that determines the amount of change in one item divided by the corresponding amount of change in another is known as an average rate of change function.

The formula for average rate of change of  function in the interval [a,b] is

[tex]\frac{f(b) - f(a)}{b-a}[/tex].

We are asked to find the rate of change when x = -3 to 6

From graph

when x = -3 , y = -2

when x = 6, y = 2

So average rate of change of function = [tex]\frac{f(6) - f(-3)}{6-(-3)} = \frac{2 - (-2)}{9} = \frac{4}{9}[/tex]

Therefore Leonard gave the correct value of approximate average rate of change of function.

The two values of y such that the barn is 50 yards from the well

The length of line in an ordered pair is calculated using the formula

d = √{(x₂ - x₁)² + (y₂ - y₁)²}

where

d = distance between the points

x₂ and x₁ = points in x coordinates

y₂ and y₁ = points in y coordinates

distance between points  (-1, 1) and (-1,, y) is calculated to be 50 yards and hence we solve for y

d = √{(x₂ - x₁)² + (y₂ - y₁)²}

50 =√{(-1 - -1)² + (1 - y)²}

50 =√{ (1 - y)²}

2500 = (1 - y) (1 - y)

2500 = 1 - 2y + y²

y² - 2y - 2499 = 0

[tex]\cos \theta=\dfrac{2}{3}[/tex]

[tex]\sin \theta=-\dfrac{\sqrt{5}}{3}[/tex]

Step-by-step explanation:

To find the exact values of the trigonometric functions of θ, we can use the following trigonometric identities:

[tex]\boxed{\begin{minipage}{4 cm}\underline{Trigonometric Identities}\\\\$\sec x=\dfrac{1}{\cos x}$\\\\\\$\tan x=\dfrac{\sin x}{\cos x}$\\\\\\$\sin^2x+\cos^2x=1$\\\end{minipage}}[/tex]

In quadrant IV, cosine of the angle is positive, whereas sine of the angle is negative.

Given that sec θ = 3/2, and secant is the reciprocal of cosine:

[tex]\sec \theta=\dfrac{3}{2}[/tex]

[tex]\dfrac{1}{\cos \theta}=\dfrac{3}{2}[/tex]

[tex]\boxed{\cos \theta=\dfrac{2}{3}}[/tex]

To find sin θ, we can substitute the found value of cos θ into the Pythagorean identity:

[tex]\sin^2 \theta+\cos^2 \theta=1[/tex]

[tex]\sin^2 \theta+\left(\dfrac{2}{3}\right)^2=1[/tex]

[tex]\sin^2 \theta=1-\left(\dfrac{2}{3}\right)^2[/tex]

[tex]\sin \theta=\sqrt{1-\left(\dfrac{2}{3}\right)^2}[/tex]

[tex]\sin \theta=\dfrac{\sqrt{5}}{3}[/tex]

As sine of the angle is negative in quadrant IV:

[tex]\boxed{\sin \theta=-\dfrac{\sqrt{5}}{3}}[/tex]

Finally, substitute the values of sin θ and cos θ into the tan θ identity to find tan θ:

[tex]\tan \theta=\dfrac{\sin \theta}{\cos \theta}[/tex]

[tex]\tan \theta=\dfrac{-\frac{\sqrt{5}}{3}}{\frac{2}{3}}[/tex]

[tex]\boxed{\tan \theta=-\dfrac{\sqrt{5}}{2}}[/tex]

Therefore, the exact values of the trigonometric functions for θ are:

[tex]\sin \theta=-\dfrac{\sqrt{5}}{3}[/tex]

Submarine 2 will reach a depth of -1,056 feet below sea level in the fastest time.

It will take the faster submarine 44 minutes to reach a depth of -1,056 feet below sea level.

Since the proportional equation for Submarine 1 is y = -22x.

In order to determine which submarine will reach a depth of -1,056 feet below sea level in the fastest time, we need to find the proportional equation for Submarine 2 using the graph.

From the graph:

proportionality constant = depth/time

proportionality constant = -120/5 = -24

y = -24x

Since the proportionality constant of Submarine 2 (-24) is greater than that of Submarine 1 (-22). Thus, Submarine 2 will reach a depth of -1,056 feet below sea level in the fastest time.

The faster submarine is Submarine 2:

On evaluating, the function f(x) and g(x) the values of f(g(3)) = - 11 and f(g(x)) = -35x + 22.    

A relation between a collection of inputs and outputs is known as a function. A function is an association between inputs in which each input is connected to approximately one output. To find f(a) for a given function f(x) we simply substitute 'a' instead of 'x' in the given function f(x).

Here we have

f(x) = 7x - 5 and g(x) = - 5x + 4

10. f(g(3))  

To find g(3) take x = 3 in g(x)

=> g(3) = - 5(3) + 4 = - 15 + 4 = 11  

=> g(3) = - 11

To find f(g(3))  take x = g(x) = - 11 in f(x)

f(g(3)) = 7(-11) - 5 =  - 77 - 5 = - 82

∴ The value of f(g(3)) = - 11  

11. f(g(x)

To find f(g(x)) take x = g(x)
