The monthly salary of an executive is $6483.

What is monthly salary?

A salary is the amount of money that an employee receives from their employer each month, particularly when they work in a profession like education, law, or medical.

Given: An executive in an engineering firm earns a monthly salary plus a Christmas bonus of 5700 dollars. She earns a total of 83500 dollars per year.

To find the salary for each month.

First to subtract the Christmas bonus from the total amount.

83500 - 5700 = 77800.

So, the salary from each month is,  77800/12 = 6483

Therefore, the salary for each month is, $6483.

a. A car travels 97.5 miles in 1.5 hours.

b. A car takes 2 hours to travel 130 miles.

c. Mai's equation matches the story because it is algebraic form of the formula of speed.

In this question, we have been given a car is going 65 miles per hour down the highway.

Part a.

A car is going 65 miles per hour.

This means, in 1 hour car traveled 65 miles.

Let car travels 'm' miles in 1.5 hours.

So, m = 1.5 × 65

m = 97.5 miles

Thus, a car travels 97.5 miles in 1.5 hours

Part b.

Suppose that it will take t hours to travel 130 miles.

We have been given 1 hour = 65 miles

So, we get an equation,

t = 130 / 65

t = 2 hours

This means, a car takes 2 hours to travel 130 miles.

Part c.

Mai wrote the equation y = 65x, with x representing the time traveled, in hours, and y representing the distance traveled, in miles.

We know that the formula of speed.

speed = distance / time

⇒ distance = speed × time

here, speed = 65 miles per hour

⇒ distance = 65 × time

Assuming distance = y  and time = x

y = 65x

This means,  Mai's equation matches the story.

Therefore, a. A car travels 97.5 miles in 1.5 hours.

b. A car takes 2 hours to travel 130 miles.

c. Mai's equation matches the story because it is algebraic form of the formula of speed.

 3/4mile part of her walk completed by Sonia once she has walked 3/5 mile of 4/5 mile distance.

As given in the question,

Sonia takes a walk everyday which is equal to

Moreover, she has completed a part of her daily targeted distance =  3/5 mile

We need to find, what part of the total distance which Sonia covers daily, has she covered just now by covering 3/5 mile of distance.

Part of the total distance which Sonia covers daily, from the distance she has covered just now by covering 3/5 mile of distance

= (Distance covered by Sonia)/ (Total distance covered by Sonia)

= (3/5) / (4/5)

A linear function which has the same y-intercept of 5 as the one that is represented by the graph is: table 1.

Mathematically, the slope of any linear function can be calculated by using this formula;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

At points (-3, -4) and (-1, 2), the slope of the line is given by:

Slope, m = (2 + 4)/(-1 + 3)

Slope, m = 6/2

Slope, m = 3.

Note: The y-intercept of the line shown on the graph is 5.

At points (-3, -4), the y-intercept of this line can be calculated by using the slope-intercept form:

y = mx + c

Where:

Making y-intercept (c) the subject of formula, we have:

y-intercept, c = y - mx

y-intercept, c = -4 - 3(-3)

y-intercept, c = -4 + 9

Using an exponential function, the sound intensity of a noise that is 130 dB is of I = 10 watts/m².

The sound level, in dB, of a sound of intensity given by I is given according to the following equation:

[tex]B = 10\log{\left(\frac{I}{I_0}\right)}[/tex]

In which [tex]I_0[/tex] is the smallest sound heard by the human ear, which is of [tex]I_0 =  10^{-12}[/tex] watts/meter.

Hence, for a sound of 130 db, the intensity I is found as follows:

[tex]130 = 10\log{\left(\frac{I}{10^{-12}}\right)}[/tex]

Isolating the logarithm, the equation is:

[tex]\log{\left(\frac{I}{10^{-12}}\right)} = 13[/tex]

The power of 10 and the logarithm are inverse functions, hence the power of 10 is applied to both sides of the equation to isolate the intensity creating the exponential function given as follows:

[tex]10^{\log{\left(\frac{I}{10^{-12}}\right)}} = 10^{13}[/tex]

[tex]\frac{l}{10^{-12}} = 10^{13}[/tex]

[tex]l = 10^{-12} \times 10^{13}[/tex]

The simplest method for locating a quadratic equation's roots is the quadratic formula. There are some quadratic equations that are difficult to factor, and in these cases we can quickly discover the roots by using the quadratic formula.

Gives the roots of a quadratic equation ax² + bx + c = 0.

x = [-b ± √(b² - 4ac)]/2a.

Now, We get

t= [-900 ± √((900)² - 4(-16)(-8825))]/2(-16)

t=[-900 ± √(810000-564800)]/-32

t=[-900 ± √(245200)]/-32

t=[-900 ± 495.17]/-32

First,

t=[-900 + 495.17]/-32

t=[-404.83]/-32

t=12.65

Second,

t=[-900 - 495.17]/-32

t=[-1395.17]/-32

t=43.59

Using equation, the number of hours Ajay spent washing car and tutoring are 2 and 4 hours respectively.

Ajay is working two summer jobs working $8 per hour washing cars and $11 per hour tutoring.

Last week Ajay worked 2 more hours tutoring than hours washing cars and earned a total of $60.

The system of equation that could be used to determine the number of hours Ajay worked washing cars last week and the number of hours he worked tutoring last week can be calculated as follows:

let

x = number of hours washing cars

y = number of hours tutoring

Therefore,

y = 2 + x

Hence,

8(x) + 11(2 + x) = 60

8x + 22 + 11x = 60

19x  = 60 - 22

By analyzing the geometric system, the measure of the angle RSP is equal to 49°.

In this problem we find a geometric system formed by two triangles, in which the line segment QR is parallel to the line segment PS. Then, we can obtain the following system of linear equations:

Intern alternate angles between parallel line segments

m ∠ QRP = m ∠ RPS

5 · y + 14 = 8 · y - 13

27 = 3 · y

y = 9

Internal angles of a triangles

m ∠ RPS + m ∠ PRS + m ∠ RSP = 180°

(8 · y - 13) + 3 · x + (2 · x + 1) = 180

8 · y + 5 · x - 12 = 180

8 · y = 180 + 12 - 5 · x

5 · x = 192 - 8 · y

x = (192 - 8 · y) / 5

x = (192 - 8 · 9) / 5

x = (192 - 72) / 5

x = 120 / 5

x = 24

Finally, the measure of the angle RSP is:

m ∠ RSP = 2 · x + 1

m ∠ RSP = 2 · 24 + 1

m ∠ RSP = 49

The equation of the function is given as

f(x) = 4x³ - x² + 16x - 4

Factor out x from the equation of the function

So, we have

f(x) = 4x³ - x² + 16x - 4

Group the terms in 2's

f(x) = (4x³ - x²) + (16x - 4)

First I substitute the Y with 0 and then I move the 16x^2 to the left side of the equation and then I divide both sides with 16 leaving me with x^2 then I get the square root of both sides and then I evaluate it and then I got the answer x = 4

Answer:

4 seconds

Step-by-step explanation:

We have a quadtratic equation, that is, we have a function to the highest degree of x^2.

When solving this, we can either solve using the quadratic equation, or by solving for X which would be the easiest and quickest way to do it.

256 -16x^2=0

-16x^2=-256

x^2=16 (divide both sides by -16)

[tex]\sqrt{x} =\sqrt{16}[/tex]

Which leaves x=4 as your answer.

To check this, we can simply input 4 back into the equation, and we will find that it does indeed equal 0.

To further visualize this, when we solve the equation for x, we are finding where the x value that intersects the x axis.  We are finding where x=0, or when it touches the ground.

The coordinates of T are (13, -6) which s is the midpoint of rt r(-9,4) and s(2,-1).

A midpoint is defined as in the middle of the line connecting two points a position known as a midpoint. A location in the middle of a line connecting the two points that are equally far from both points is the midpoint.

Let two points A (x₁, y₁) and B (x₂, y₂), the midpoint between A and B is given by,

M(x, y) = (x₁ + x₂)/2, (y₁ + y₂)/2

Assuming that S is the midpoint of the line segment RT, where point R's coordinates are (-9, 4) and S's coordinates are (2, -1).

We have to determine the coordinates of point T.

The midpoint is the average of both endpoints. i.e., (x₁, y₁) and (x₂, y₂).

In this case, the midpoint is given by M = S(2, -1).

Let R(x₁, y₁) = R(-9, 4) and we will determine T(x₂, y₂).

2 = (-9 + x₂)/2

-9 + x₂ = 4

x₂ = 13

-1 = (4 + y₂)/2

4 + y₂ = -2

y₂ = -6

As per the question statement, two points having coordinates (4, -4) and

We are required to calculate the distance between the above mentioned two points, rounded to the nearest tenth.

To solve this question,  we need to know the Distance-formula which goes as,

"The distance between any two points (x₁, y₁) and (x₂, y₂) can be given by √[(x₂ - x₁)² + (y₂ - y₁)²]"

Assuming that [(x₁, y₁) = (4, -4)] and [(x₂, y₂) = (9, -2)], and substituting these values in the above-mentioned distance formula, we get,

√[(9 - 4)² + {(-2) - (-4)}²]

= √[(9 - 4)² + {(-2) + 4}²]

= √[(9 - 4)² + (4 - 2)²]

=√[(5)² + (2)²]
