Find p (-5) p(3) for p(x)=2x^5-9x^4-2x^2+12x-2

Mathematics
1 answer:
Margarita [4]3 years ago
8 0

Answer:

We have to evaluate the function p with the numbers on the argument of them, that is:

p(-5) = -11887

p(3)= -191

Step-by-step explanation:

First we are going to evaluate the functions and then to replace x by the corresponding number on the argument:

p(-5)= 2 (-5)^5 -9(-5)^4 -2(-5)^2+12(-5) +2 = -11887

p(3) =2(3)^5-9(3)^5-2(3)^2+12(3)-2 =-191

The equations of two functions are y=-21x+9 and y=24x+8 which function is changing more quickly? Explain
antoniya [11.8K]

Given:

The equations are

y=-21x+9

y=24x+8

To find:

Which function is changing more quickly.

Solution:

The slope intercept form of a line is

y=mx+b

Where m is slope and b is y-intercept.

On comparing y=-21x+9 with the slope intercept form, we get

m_1=-21

|m_1|=|-21|

|m_1|=21

On comparing y=24x+8 with the slope intercept form, we get

m_2=24

|m_2|=24

Since, |m_1|, it means the absolute rate of change of second function is greater than the first function.

Therefore, the second function is changing more quickly.

What is the sum of the measures of the interior angles of a regular polygon if each exterior angle measures 120?
IrinaVladis [17]
The answer would be 180 because the sum of the exterior angles would equal 360 and 360 divided by 120 equals 3 so that means there are 3 sides. Next you find out how much the interior angle is worth by subtracting it from 180 because they're supplementary you would find that the interior angle is equal to 60 degrees then multiply 60 degrees by how many sides there are (3) which equals 180 degrees.

A specific park is rectangular-shaped and has a 3 mile-perimeter. The length is 4 times the width. What are the dimensions of th
avanturin [10]

Answer:

The length of the rectangular park is 1.2\ mi and the width of the rectangular park is 0.3\ mi

Step-by-step explanation:

Let

x ----> the length of the rectangular park

y ---> the width of the rectangular park

we know that

The perimeter is equal to

P=2(x+y)

P=3\ mi

so

3=2(x+y) -----> equation A

x=4y ----> equation B

substitute equation B in equation A and solve for y

3=2(4y+y)

3=10y

y=0.3\ mi

Find the value of x

x=4(0.3)=1.2\ mi

therefore

The length of the rectangular park is 1.2\ mi and the width of the rectangular park is 0.3\ mi
