The equation for the flowing rate of aamir is as follows y  =  -12x  +360

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

First of all let's write the slope-intercept form of the equation of a line, which is:

y   =  mx  +  c

So we just need to find to solve this problem.

Moreover, this problem tells us that Amir drove from Jerusalem down to the lowest place on Earth, the Dead Sea, descending at a rate of 12 meters per minute. So this rate is the slope of the line, that is:

Negative slope because Amir is descending. So:

y    =  -   12x  +  b

To find, we need to use the information that tells us that he was at sea level after 30 minutes of driving, so this can be written as the point. Therefore, substituting this point into our equation:

y  =  -12x  +  b

0  =   -12(30)   +  b

b   =   360

Finally, the equation of Amir's altitude relative to sea level (in meters) and time (in minutes) is:

y  =  -12x  +360

Answer:

11 meters per minute

Step-by-step explanation:

The rate at which Amir descended is equivalent to the rate of change of this relationship. In linear relationships, the rate of change is represented by the slope of the line. We can calculate this slope from any two points on the line.

Answer:

hope this help you

Step-by-step explanation:

[tex] \cos(y) = \frac{b}{h} \\ \cos(y) = \frac{8}{12} \\ y = \cos {}^{ - 1} ( { 0.6666}^{ } ) \\ y = 48.19[/tex]

The option (C) x-axis, scale: 1 unit = 1 week and y-axis, scale: 1 unit = 150 minutes with origin (0 weeks, 0 minutes) is correct.

The ratio among comparable dimensions of an object and a model with that object, known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.

As we can see in the table, data is given, we can plot it in the graph by using the scale factor.

On the x-axis, scale: 1 unit = 1 week

On the y-axis, scale: 1 unit = 150 minutes

On the y-axis, 2 units = 300 minutes

On the y-axis, 3 units = 450 minutes

Thus, the option (C) x-axis, scale: 1 unit = 1 week and y-axis, scale: 1 unit = 150 minutes with origin (0 weeks, 0 minutes) is correct.

The percentage of the rectangle that will be beige is 15.5 percent

A rectangle is a quadrilateral having the four sides and the sum of the angles is 180 in the rectangle the opposite two sides are equal and parallel and the two sides are at 90-degree angles.

The width of the "H" is 1/2 the distance form the top to the bottom of the "H" is 1/2

1/2 + 1/2 =

the side length of the "H" is 4

4 x 1/2 = 2

The demensions of the other 1/2 by 4 are the same, therefore,

2 + 2 = 4

The middle section is 1 by 1/2

1 x 1/2 = 1/2

The equation is 2 + 1/2 = 2 1/2

It helps to transform the equation into vertex form by completing the square because it tells us a lot about the characteristics of the parabola:

[tex]\displaystyle y=-6x^2+12x-8\\\\y=-6\biggr(x^2-2x+\frac{4}{3}\biggr)\\\\y-6\biggr(-\frac{1}{3}\biggr) =-6\biggr(x^2-2x+\frac{4}{3}-\frac{1}{3}\biggr)\\\\y+2=-6(x^2-2x+1)\\\\y+2=-6(x-1)^2\\\\y=-6(x-1)^2-2[/tex]

Since vertex form is [tex]y=a(x-h)^2+k[/tex], we identify the vertex to be [tex](h,k)\rightarrow(1,-2)[/tex] and the axis of symmetry to be [tex]x=h\rightarrow x=1[/tex]. The y-intercept can be found by setting [tex]x=0[/tex] and evaluating:

The measure of the cscθ and secθ are 5/4 and 5/3 respectively option (A) is correct.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have a standard-position angle determined by the point (x, y).

The point is (9, 12)

From the Pythagoras theorem, we can find the hypotenuse(h):

h  = √(9²+12²)

h = 15

cscθ = hypotenuse/opposite = 15/12 = 5/4

secθ = hypotenuse/adjacent = 15/9 = 5/3

Thus, the measure of the cscθ and secθ are 5/4 and 5/3 respectively option (A) is correct.

Step-by-step explanation:

1. Group all a terms on the left side of the equation

Add a to both sides

[tex]46a+\frac{5}{3}+a=\frac{24}{5}-a+a[/tex]

Group like terms:

[tex]46a+a+\frac{5}{3}=\frac{24}{5}-a+a[/tex]

Simplify the arithmetic:

[tex]47a+\frac{5}{3}=\frac{24}{5}-a+a[/tex]

Group like terms:

[tex]47a+\frac{5}{3}=-a+a+\frac{24}{5}[/tex]

Simplify the arithmetic:

[tex]47a+\frac{5}{3}=\frac{24}{5}[/tex]

2. Group all constants on the right side of the equation

[tex]47a+\frac{5}{3}=\frac{24}{5}[/tex]

Subtract [tex]\frac{5}{3}[/tex] from both sides:

[tex]47a+\frac{5}{3}-\frac{5}{3}=\frac{24}{5}-\frac{5}{3}[/tex]

Combine the fractions:

[tex]47a+\frac{5-5}{3}=\frac{24}{5}-\frac{5}{3}[/tex]

Combine the numerators:

[tex]47a+\frac{0}{3}=\frac{24}{5}-\frac{5}{3}[/tex]

Reduce the zero numerator:

[tex]47a+0=\frac{24}{5}-\frac{5}{3}[/tex]

Simplify the arithmetic:

[tex]47a=\frac{24}{5}-\frac{5}{3}[/tex]

Find the lowest common denominator:

[tex]47a=\frac{24\cdot 3}{5\cdot 3}+\frac{-5\cdot 5}{3\cdot 5}[/tex]

Multiply the denominators:

[tex]47a=\frac{24\cdot 3}{15}+\frac{-5\cdot 5}{15}[/tex]

Multiply the numerators:

[tex]47a=\frac{72}{15}+\frac{-25}{15}[/tex]

Combine the fractions:

[tex]47a=\frac{72-25}{15}[/tex]

Combine the numerators:

[tex]47a=\frac{47}{15}[/tex]

3. Isolate the a

[tex]47a=\frac{47}{15}[/tex]

Divide both sides by 47:

[tex]\frac{47a}{47}=\frac{\frac{47}{15}}{47}[/tex]

Simplify the division:

[tex]a=\frac{47}{15\cdot 47}[/tex]

Simplify the right side:

[tex]a=\frac{1}{15}[/tex]

Inequality is defined as a mathematical expression in which both sides are not equal and have mathematical signs that are either less than or greater than.

Let's suppose the total minutes of uses for cell phone is x

and total minutes of uses of for tablet is y

Cell phone cost $0.10 each minute and tablet cost $0.15 each minute.

Then total minutes will be:

x + y < 5000 (as it is given that the time will be less than 5,000 minutes on both of the devices)

And total cost = $450

0.10x + 0.15y ≤ $450

Thus, the inequalities are x + y < 5000 and 0.10x + 0.15y ≤ $450 which shows each month, you want to only spend up to $450 and use less than 5,000 minutes on both of the devices.
