Based on the end behaviors, which graph is the graph of f(x) = -2x4 − 4x3 + x2 + x + 3?

Answers

Given:

The function is

[tex]f(x)=-2x^4-4x^3+x^2+x+3[/tex]

To find:

The graph of the function by using the end behaviors.

Solution:

We have,

[tex]f(x)=-2x^4-4x^3+x^2+x+3[/tex]

The degree of the polynomial is 4 which is even and the leading coefficient is -2, which is negative. So,

[tex]f(x)\to -\infty\text{ as }x\to -\infty[/tex]

[tex]f(x)\to -\infty\text{ as }x\to \infty[/tex]

It means, the graph of the function approaches to negative infinity on the both ends.

Therefore, the correct option is C.

A square has an area of 12x^2 square feet. What is the length of its sides?

Answers

The area of a rectangle is found by multiplying the length by the width or L*W.
In a square the length and width are the same so just call the value
s for each side.

l*w = s*s = s2

In this case we have
s2 = 12x2 Take square root of both sides
s = √(12x2)
s = x√12
s = x√(4*3)
s = x√(22*3)
s = 2x√3

If you want the variable at the end of the number
you can write this as (2√3)x
I only put the parentheses to denote that the
term x is not part of the square root.

6. The total cost of materials to build the foam
pit is $1,285.20. What is the cost of materials
per square foot?

Answers

Answer:

Cost of Material per square foot = $1.7

Step-by-step explanation:

Given:

Length = 24

Width = 12

Height = 6.5

Find:

Cost of Material per square foot

Computation:

TSA of pit = 2[bh + hl] + lb

TSA of pit = 2[(12)(6.5) + (24)(6.5)] + (24)(12)

TSA of pit = 2[78+156] + 288

TSA of pit = 756 square foot

Cost of Material per square foot = 1,285.20 / 756

Cost of Material per square foot = $1.7

Jan rode to her friend's house with a constant speed of 14 m/hr. How long will she take to
travel the 15 miles there?

Answers

Answer:

1.07 hours

Step-by-step explanation:

14 miles = 1 hour

15 miles = x hours

Equal these two together

14 mi/1hr = 15 mi/xhr

Cross multiply

14 mi × x hr = 1 hr × 15 mi

I will stop using the units for now so it won't be as confusing

14x = 15

Divide both sides by 14 to isolate the variable

14x ÷ 14 = 15 ÷ 14

x = 1.07... hours

Circle A has center of (6, 7), and a radius of 4 and circle B has a center of (2, 4), and a radius of 16.

Answers

Answer:

See solutions below

Explanation

We are to find the equation of circle A and B

The equation of a circle is expressed as;

(x-a)^2 + (y-b)^2 = r^2

(a, b) is the centre and r is the radius

For Circle A that has center of (6, 7), and a radius of 4

Substitute;

(x-6)^2 + (y-7)^2 = 4^2

(x-6)^2+(y-7)^2 = 16

Hence the equation of circle A is (x-6)^2+(y-7)^2 = 16

For circle B:

If circle B has a center of (2, 4), and a radius of 16

The equation is expressed as;

(x-2)^2+(x-4)^2 = 16^2

(x-2)^2+(x-4)^2 = 256

Hence the required equation is (x-2)^2+(x-4)^2 = 256

EXPLAIN how you would graph the line y = 1/3x + 5

Answers

Answer:

Okay so this is the best way to explain it, its already in y=mx+b form which is the easiest way to graph something, its where m= slope and b=the y-intercept  so 1/3 is m so the slope is 1/3 but first we need to mark the y coordinate which is 5, so on your graph dot (0,5) then from that go up 1 and right 3 then that should be your graph!!!

Step-by-step explanation:

9 x 18 = 162 back side

9^2 + 12^2 = c^2

9^2 + 12^2 = 225

9^2 + 12^2 = 15^2

length of the hypotenuse is 15 so

18 x 12 = 216 bottom

216 + 270 + 162 + 108 = 756 cm^2

I need to know X for 8 and 10 if u feel like it. PLS

Answers

Answer:

8) x=9

10) 23 degrees

Step-by-step explanation:

8) vertical angles are congruent to each other so we can set the expressions as such and solve:

7x + 3 = 10x - 24

3 = 3x - 24

27 = 3x

9 = x

10) since the angles are complementary they equal 90 degrees, so we can set the expression like this and solve for x:

12x + 7 + 6x - 7 = 90

18x + 7 - 7 = 90

18x = 90

x = 5

now we plug it back into the expression equivalent to the measure of angle O:

6(5) -7

30 - 7

23 degrees
