The value of m<DEC is given as 35 degrees

In the given figure, to find the missing value of angle DEC, we can easily relate this to angle on a straight line.

The law states that the sum of all angles on a straight line are equal to 180 degrees.

[tex]m < CEF + m < DEC = 180^0\\145^0 + m < DEC = 180^0\\m < DEC = 180^0 - 145^0\\m < DEC = 35^0[/tex]

The value of the angle m<DEC is equal to 35 degrees.

Answer:

Y= 1/2

Gradient= y2-y1/x2 -x2=m

Given that:

y2=1

y1=Y

x1=-4

x2=-5

1-y/-4-(-5) =2

1 - y/-4+5 =2

cross multiply

2(1-y) = -4+5

2-2y =1

-2y =1-2

-2y = -1

divide both sides by the coefficient of y

Y = 1/2

The linear function is V(x) = 800x + 2400.

Given,

The cost of computer when purchased (the initial book value), V = 2400 (x = 0)

Company chooses to depreciate for 3 years using straight line method.

The book value after 3 years = 0 (x = 3)

We have to write a linear function that expresses the book value of the computer as a function of its age V(x).

Here, the value is depreciating over 3 years.

That is 2400 in 3 years = 2400/3 = 800

That is depreciating $800 in a year.

Now we can write the equation as:

V(x) = 800x + 2400

When we consider slope-intercept form, we can check that the above given equation of a line passes through two points: (0, 2400) and (3, 0)

1.111 liters of water must be added to 5 kilograms of soil.

According to the statement, water percentage is equal to the ratio of water mass divided by the total mass of water and dust and multiplied by 100. Then, the initial and final percentages are defined below:

Initial percentage

y / 5 = 0.12                              (1)

Final percentage

(y + x) / (5 + x) = 0.28             (2)

Then, we need to resolve the resulting system of linear equations:

y = 0.6                  (1)

y + x = 1.4 + 0.28 · x

0.72 · x = 1.4 - y

x = 1.944 - 1.389 · y

x = 1.111

We need to add 1.111 kilograms of water. If the density of a kilogram per liter, the volume required in liters is:

The solution for the unknown variable in I = PRT where I = 2160, P =24000 and R = 0.03 is 3

The given parameters are

I = PRT

Where

I = 2160, P =24000 and R = 0.03

Substitute I = 2160, P =24000 and R = 0.03 in the above equation I = PRT

2160 = 24000 * 0.03 * T

Evaluate the product

So, we have

2160 = 720 * T

Divide both sides by 720

T = 3

Hence, the solution for the unknown variable in I = PRT where I = 2160, P =24000 and R = 0.03 is 3

The population of the Bownville city reach 1,548,800 at nearly 2015

Given, Since January 2000,

The population of the city of Brownville has grown according to the mathematical model.

Y= 720,500(1.022) x

Where, X= number of years

To find:  If this continues, predict the year during which population of Brownville will reach 1,548,800

Starting population = 720,500

Growth rate = 1.022

(720500) (1.022) x = 1,548,800

1.022x = 2.1496

Taking log on both sides

log1.022x = log2.1496

x log 1.022 = log 2.1496

x=log 1.022×2.1496

x=15

Therefore, nearly it takes 15 years to reach the population 1,548,800

Hence the population of the Bownville city reach 1,548,800 at nearly 2015.

The domain is all real numbers and the range is 21 for the given function that is f(x) = 21.

According to the question, the domain can take only those values through which expression can be defined. And the range is the set of values for the given function.

Therefore, the function is: f(x) = 21

So, for this expression, the variable 'x' can take any real values from the interval of (-∞ , ∞).

And the range is 21 for the given function.

Hence the domain is (-∞ , ∞) and the range is 21.

What is domain and range in the function?

The domain of a function can be defined as the complete set of all the possible values for the dependent variables. Similarly, the range of the function can be expressed as the set of all the values which can be assumed by the expression of the function.

No: g(x) of not the inverse function of f(x)

Given data

f(x) = -4 ( -2x + 9 )^3 - 8

g(x) = - cube root ( -5x + 6 ) + 2

f(x) = -4 ( -2x + 9 )^3 - 8

dividing through by - 4 gives

= ( -4 ( -2x + 9 )^3 ) / -4 - ( 8  / -4)

= ( -2x + 9 )^3 -  ( -2 )

=  ( -2x + 9 )^3 + 2

finding the cube root

= ( -2x + 9 )^3 + 2

= cube root ( ( -2x + 9 )^3 + 2 )

= ( -2x + 9 ) +  cube root ( 2 )

( -2x + 9 ) +  cube root ( 2 ) ≠ g(x) = - cube root ( -5x + 6 ) + 2

Explanation:

The preimage (-6,-2) shifts to the image point (-4,-4)

Focus on the x coordinates. The jump from -6 to -4 is an increase of 2. So we have x become x+2

Now focus on the y coordinates. The jump from -2 to -4 is -2, so y becomes y-2

The translation rule we use is [tex](\text{x},\text{y})\to (\text{x}+2,\text{y}-2)[/tex] which shifts the point 2 units to the right and 2 units down.

-----------------

Let's apply this rule to the point (3,-1)

[tex](\text{x},\text{y})\to (\text{x}+2,\text{y}-2)\\\\(3,-1)\to (3+2,-1-2)\\\\(3,-1)\to \boldsymbol{(5,-3)}\\\\[/tex]

The preimage (3,-1) shifts to the image (5, -3)

Answer:

A) x = m - n - p

Step-by-step explanation:

m - x = n + p

subtract m from both sides

m - x (- m) = n + p (- m)

m cancels out on the left and stays on the right

- x = n + p - m

divide by -1 because this is the constant in front of x

visualize as -1*x if it helps (anything multiplied by 1 is that number)

(- x / -1) = (n / -1) + (p/ -1) - (m/ -1)

the positives become negative and the negatives become positive

x = -n - p + m or x = m - n - p
