Find the sum of (5x3 + 3x2 - 5x + 4) and (8x3 -5x2 + 8x + 9).

Answers

Answer 1

Answer: If you would like to solve (5 * x^3 + 3 * x^2 - 5 * x + 4) + (8 * x^3 - 5 * x^2 + 8 * x + 9), you can calculate this using the following steps:

(5 * x^3 + 3 * x^2 - 5 * x + 4) + (8 * x^3 - 5 * x^2 + 8 * x + 9) = 5 * x^3 + 8 * x^3 + 3 * x^2 - 5 * x^2 - 5 * x + 8 * x + 4 + 9 = 13 * x^3 - 2 * x^2 + 3 * x + 13

The correct result would be 13 * x^3 - 2 * x^2 + 3 * x + 13.

Answer 2

Answer: $(5x^3+3x^2-5x+4)+(8x^3-5x^2+8x+9)=\n\n13x^3-2x^2+3x+13$

$\sf\ Answer:\ {\boxed{13x^3-2x^2+3x+13}$

How do you convert sin into cos, and vice versa.. Promblem: cos(6x) = sin(3x-9)

Answers

The rule for converting sin into cos and vice versa is:
sin α = cos ( 90° - α ) or cos α = sin ( 90° - α )
In this case:
cos ( 6 x ) = sin ( 90° - 6 x )
sin ( 90° - 6 x ) = sin ( 3 x - 9°)
90° - 6 x = 3 x - 9°
90° + 9° = 3 x + 6 x
99° = 9 x
x = 99° : 9 = 11°
Answer: C ) x = 11°

HELP!!!!!!!! The histogram below shows the estimated monthly salaries of company employees with different years of experience. How might the graph be misleading?

Answers

The scale on the x-axis is not completed for the expected monthly salary.

What is a histogram?

A diagram is made up of rectangles whose size is related to a variable's frequency and whose length is similar to the measurement range.

The histogram below shows the estimated monthly salaries of company employees with different years of experience.

The scale for the graph's x-axis (i.e. Years of Experience) does not completely account for the expected monthly salary (scale on the y-axis).

More about the histogram link is given below.
