Fox2110Which quadratic function is represented by the table?o f(x) -3x2 2x 5f(x) 2x2 -2x 5

Answers

Answer 1

Answer:

Answer:

$3x^(2)-2x+5$

Step-by-step explanation:

The value for each value of x is given by f(x) in the table, the quadratic equation which satisfies all the values f(x) at each value of x is given by:

$3x^(2)-2x+5$ .

This can be found by substituting all the values of x in the equation and check whether it satisfies the corresponding value f(x) or not.

Therefore, substituting x=-2 in the quadratic equation $3x^(2)-2x+5$ ,

$3(-2)^(2)-2(-2)+5$

$3(4)+4+5$

= $21$

Again, substituting x=-1 in the same equation, we have

$3(-1)^(2)-2(-1)+5$

$3+2+5$

= $10$

Putting x=0,

$3(0)^(2)-2(0)+5$

= $5$

Putting x=1,

$3(1)^(2)-2(1)+5$

= $6$

Putting x=2,

$3(2)^(2)-2(2)+5$

=13

Hence, the quadratic equation which is represented by the table is $3x^(2)-2x+5$

Answer 2

Answer: B) f(x) = 3x^2 -2x + 5

Answers

(-8x^6) / (4x^3) can be broken down as (-8/4) * (x^6/x^-3)
you should know that -8/4 is -2
the second part is dividing variables at different powers which is kinda like subtracting powers

Please help put a bunch of points for this question do

Answers

Answer:

Label: About 527.9 square centimeters

Aluminum: About 835.7 square centimeters

Step-by-step explanation:

Amount of paper needed for the label:

You can imagine taking off the label and unrolling it, forming a rectangle. The height of this rectangle will be the height of the cylinder, while the length of the rectangle will be the circumference of the cylinder. Therefore, the area of that rectangle will be $2\pi r h= 2 \cdot \pi \cdot 7 \cdot 12\approx 527.9$ .

Amount of aluminum needed for the can:

This time, you need to add in the top and bottom of the can as well, which each have area $\pi r^2$ . Together, they have area $2\pi r^2=2\cdot \pi \cdot 7^2\approx 307.9$ . Adding this to the area of the sides, you get a total of about 835.7 square centimeters.

Hope this helps!

What is the area of this triangle? And it's not 60, I already checked. PLEASE EXPLAIN!!!!

Answers

Answer:

A = 4 cm^2

Step-by-step explanation:

The area of a triangle is

A = 1/2 b*h

The base is 4 and the height is 2

A = 1/2 ( 4*2)

A = 1/2*8

A = 4 cm^2

Answer:

Step-by-step explanation:

A = BH/2

or Area = Base multiplied by Hieght divided by 2.

(b)4 x (h)2 = 8

8/2 = 4

Keshawn is asked to compare and contrast the domain and range for the two functions.f(x) = 5x
g(x) = 5

Answers

For the function 5x, the range is the value of f(x) which is five times the x and the domain is the value of x which can be the ratio of f(x) and 5. For the second function which is g(x) = 5, the range is 5 all through out the graph while the domain is infinity.
