A househelp receives as salary of 36,000 a year with a contract of 250 annual increase for 7 years. What is his total income for 7 years? Show the solution

Answers

Answer 1

Answer:

Answer:

The total income is 257,250

Step-by-step explanation:

The initial value of salary is 36,000 a year with an increase of 250 every year. Next is presented the salary table of each year:

Year Salary

36,000
36,250
36,500
36,750
37,000
37,250
37,500

To have the total income you have to sum all the value of the seven years.

Total income = 36,000 + 36,250 + 36,500 + 36,750 + 37,000 + 37,250 + 37,500 = 257,250 is the total income for the 7 years.

Rewrite in simplest terms: (-x+8y)+(-10x-6y)(−x+8y)+(−10x−6y)

Answers

Answer:

10x² - 48y² - 11x + 2y - 74xy

Step-by-step explanation:

(-x+8y)+(-10x-6y)(−x+8y)+(−10x−6y)

Rearranging,

=> - x - 10 x + 8y - 6y + (-10x-6y)(−x+8y)

=> - 11x + 2y + 10x² - 48y² + 6xy - 80xy

=> 10x² - 48y² - 11x + 2y - 74xy

True or false:A linear binomial has a degree of 0

A trinomial has a degree of 2

A constant has a degree of 1

A cubic monomial has a degree of 3

I will mark as the top answers of you help me!

Answers

Answer:

The degree of a binomial is zero. The product of two binomials is not a polynomial. The sum of two polynomials is a polynomial. A monomial containing ^2 has a degree of three

The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s). Examples: 5x2-2x+1 The highest exponent is the 2 so this is a 2nd degree trinomial.

3 Cubic x3−x2+5

The degree of a cubic monomial is three. A quadratic polynomial is a trinomial. The degree of a binomial is two.

Derek found a function that approximately models the population of iguanas in a reptile garden, where x represents the number of years since the iguanas were introduced into the garden.i(x) = 12(1.9)^x

Rewrite this function in a form that reveals the monthly growth rate of the population of iguanas in the garden. Round the growth factor to the nearest thousandth.

Answers

Answer:

$i(x)=12 * (1+(0.9)/(12))^(12x)$ and growth rate factor is 0.075

Step-by-step explanation:

The function that models the population of iguanas in a reptile garden is given by $i(x)=12 * (1.9)^(x)$ , where x is the number of years.

Since, $i(x)=12 * (1.9)^(x)$

i.e. $i(x)=12 * (1+0.9)^(x)$ .

Therefore, the monthly growth rate function becomes,

i.e. $i(x)=12 * (1+(0.9)/(12))^(x * 12)$ .

i.e. $i(x)=12 * (1+(0.9)/(12))^(12x)$ .

Hence, the monthly growth rate is i.e. $i(x)=12 * (1+(0.9)/(12))^(12x)$ .

Also, the growth factor is given by $(0.9)/(12)$ = 0.075.

Thus, the growth factor to nearest thousandth place is 0.075.

Hey there! :)

Answer:

(30, 0).

Step-by-step explanation:

Solve for the x-intercept, or zero of the equation by setting the equation equal to 0:

y = -2/5x + 12 becomes:

0 = -2/5x + 12

Subtract both sides by 12:

-12 = -2/5x

Divide both sides by -2/5:

-12 (-5/2) = -2/5x (-5/2)

30 = x.

Therefore, the x-intercept is at (30, 0).

Answer:

(30,0)

Step-by-step explanation:

y=0

-2/5 *x +12=0

2x/5=12

2x=12*5

2x=60

x=60/2

x=30

A store uses the expression –2p + 50 to model the number of backpacks it sells per day, where the price, p, can be anywhere from $9 to $15. Which price gives the store the maximum amount of revenue, and what is the maximum revenue? (Revenue = price mc023-1.jpg number of backpacks.) $9.00 per backpack gives the maximum revenue; the maximum revenue is $32.00. $12.00 per backpack gives the maximum revenue; the maximum revenue is $312.00. $12.50 per backpack gives the maximum revenue; the maximum revenue is $312.50. $15.00 per backpack gives the maximum revenue; the maximum revenue is $20.00.

Answers

Revenue = price * number of backpacks
number of backpacks = -2p + 50

p = 9 ; -2(9) + 50 = -18 + 50 = 32
revenue = 9 * 32 = 288

p = 12 ; -2(12) + 50 = -24 + 50 = 26
revenue = 12 * 26 = 312

p = 12.50 ; -2(12.50) + 50 = -25 + 50 = 25
revenue = 12.50 * 25 = 312.50 GIVES THE MAXIMUM REVENUE

p = 15 ; -2(15) + 50 = -30 + 50 = 20
revenue = 15 * 20 = 300
