A polynomial is defined as a collection of variables and constant terms combined by various mathematical operations. The exponents of the variables in a polynomials must be non-negative integers.

If you observe the given options, one of the option (option B) contains a negative exponent. Hence the expression in option B is not a polynomial.

Oil flows back and forth between a small and large tank. When oil is moving into the large tank, the flow rate is positive. When

amid [387]

Step-by-step explanation:

As per the question, when the flow rate is negative, oil is moving into the small tank.

The large tank started with 600 gallons of oil. The recorded flow rate was - 4 gallons/ min.

That is, In one minute, 4 gallons of oil is moving from the large tank to the small tank.

$\mathsf{oil \: transfered \: in \: 1 \: mi n\: = 4 \: gals}$

$\mathsf{oil \: transfered \: in \: 32 \: mi ns\: = (4 \times 32)\: gals} \\ = \mathsf{128 \: gals}$

Therefore, after 32 mins 128 gals of oil has flown into the small tank.

After 32 mins, the large tank lost 128 gallons of oil.

The remaining oil in the large tank = 600 - 128

= 472 gallons

On circle C points A and B are separated by an arc whose length is 18 centimeters. If the radius of C is 8 centimeters, what is

alex41 [277]

Answer:

2.25 radians

Step-by-step explanation:

First we need to find the length of the circunference, using the formula:

C = 2 * pi * r

Where r is the radius. Using r = 8, we have:

C = 2 * pi * 8 = 50.2655 cm

Now, to find the measure of the central angle related to that arc of 18 cm, we can use a rule of three, knowing that the whole circunference has a central angle of 2pi radians:

2pi rad -> 50.2655 cm

x -> 18 cm

x = 18 * 2pi / 50.2655

x = 2.25 rad

Here is a graph that represents a quadratic function. Which equation could define this function?

hoa [83]

Answer:

d. y = (x +2)(x -3)

Step-by-step explanation:

When p is a zero of the function (an x-intercept), the function has (x -p) as a factor.

Here, the x-intercepts are x = -2 and x = 3. This means the factors of the function are (x -(-2)) = (x +2) and (x -3).

y = (x +2)(x -3)

Aleksandr [31]

Answer:

65, 90, 30, 24(in order abcd)

Step-by-step explanation:

The sum of all angles in a triangle is 180 degrees, so knowing this, you should be able to get all of them.

1) x+65+50 = 180, so x= 65

2)x+34+56 =180, so x= 90

3)90+3x=180, so x=30

4)90+66+x=180, x=24
