The expression that represent the profit is given by P(r) = r⁴ - 3r³ - r² - 4

<h3>What is an equation? </h3>

An equation is an expression that shows the relationship between two or more numbers and variables. An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.

Profit is the difference between revenue and cost. Given that:

R(r) = 2r⁴ - 3r³ + 2r - 1 and C(r) = r⁴ - r² + 2r + 3

P(r) = R(r) - C(r)

P(r) = (2r⁴ - 3r³ + 2r - 1) - (r⁴ - r² + 2r + 3) = r⁴ - 3r³ - r² - 4

The expression that represent the profit is given by P(r) = r⁴ - 3r³ - r² - 4

Biểu thức đại diện cho lợi nhuận được cho bởi P (r) = r⁴ - 3r³ - r² - 4

Một phương trình là gì?

Phương trình là một biểu thức thể hiện mối quan hệ giữa hai hoặc nhiều số và biến. Một biến độc lập là một biến tha t không phụ thuộc vào các biến khác trong khi một biến phụ thuộc là một biến phụ thuộc vào các biến khác.

Lợi nhuận là khoản chênh lệch giữa doanh thu và chi phí. Cho rằng:

R (r) = 2r⁴ - 3r³ + 2r - 1 và C (r) = r⁴ - r² + 2r + 3

P (r) = R (r) - C (r)

P (r) = ( 2r⁴ - 3r³ + 2r - 1) - (r⁴ - r² + 2r + 3) = r⁴ - 3r³ - r² - 4

Biểu thức đại diện cho lợi nhuận được cho bởi P (r) = r⁴ - 3r³ - r² - 4

A sequence is defined recursively using the equation f(n + 1) = f(n) – 8. If f(1) = 100, what is f(6)?
BARSIC [14]
If the sequence f is defined as

\mathsf{f(n+1)=f(n)-8}


then

\mathsf{f(n+1)-f(n)=-8}


As you can see above, the difference between two consecutive terms gives us a constant.


So f is actually an arithmetic progression (AP), and it has (– 8) as its common difference:

\mathsf{f(n)=f(1)+(n-1)\cdot d}\\\\ \textsf{where }\mathsf{d=-8.}


•   If f(1) = 100, then

\mathsf{f(6)=f(1)+(6-1)\cdot (-8)}\\\\ \mathsf{f(6)=100+5\cdot (-8)}\\\\ \mathsf{f(6)=100-40}\\\\ \boxed{\begin{array}{l} \mathsf{f(6)=60} \end{array}}\qquad\checkmark

In the diagram of right triangle ABC shown below, AB = 14 and AC = 9. What is the measure of angle A to the nearest degree?
olga_2 [115]

This question is incomplete because it lacks the diagram of the right angled triangle. Find attached to this answer the diagram of the right angle triangle.

Answer:

d-50

Step-by-step explanation:

Looking at the attached diagram, the only way to solve for this is the use of the trigonometric function. The trigonometric function to be used is the cosine function.

From the diagram, we are given

Hypotenuse = AB = 14

Adjacent = AC = 9

The measure of angle A to the nearest degree is calculated as:

cos θ = Adjacent / Hypothenuse

cos θ = 9/14

θ = cos -¹ (9/14) or arccos(9/14)

θ = 49.994799115°

To the nearest degree = 50°

Therefore,the measure of angle A to the nearest degree = 50°

What is the sum of the 14th square number and the 2nd cube number?
tamaranim1 [39]

Answer:

204

Step-by-step explanation:

Square of 14 = 14 × 14 = 196

Cube of 2 = 2 × 2 × 2 = 8

So sum of square of 14 & cube of 2= 196 + 8 = 204
