Answer:

Fourth-degree trinomial

Step-by-step explanation:

7x⁴ + 7x³ + 10x

There are three terms, and the biggest degree (exponent) is 4. Therefore, this is a fourth-degree trinomial.

Note:

A polynomial with one term: monomial
A polynomial with two terms: binomial
A polynomial with three terms: trinomial
A polynomial with four or more terms: polynomial

A farmer decides to enclose a rectangular garden using the side of the barn as on of the sides of the recta

dedylja [7]

Answer:

Step-by-step explanation:

Let the length of the fence = x

Let the width of the fence = y

Recall that the perimeter of a rectangle is calculated by 2(L+B) , but the farmer is using the side of the barn on one side of the rectangle , so the perimeter equation is

x + 2y = 48

Area = xy

If we substitute the perimeter equation so that the area is only in terms of y.

Area = (48 - 2y)y

Area = 48y - 2 $y^{2}$

Now just find the vertex of the parabola

Area = -2 $y^{2}$ + 48y

A = -2 $y^{2}$ + 48

Differentiate A with respect to y

$\frac{dA}{dy}$ = -4y + 48

equate it to zero , we have

-4y + 48 = 0

4y = 48

y = 12

Substitute y = 12 into equation 1, we have

x = 48 - 2y

x = 48 - 2(12)

x = 48 - 24

x = 24

Therefore the dimensions of the garden are 24 by 12

The maximum area is 288 square unit

Suppose that the functions s and t are defined for all real numbers x as follows.

Svetllana [295]

$s(x)=2x+4;\ D_s=\mathbb{R}\\\\t(x)=5x;\ D_t=\mathbb{R}\\\\D_s=D_t\\\\(s+t)(x)=s(x)+t(x)=2x+4+5x=7x+4\\\\(s-t)(x)=s(x)-t(x)=2x+4-5x=-3x+4\\\\(s\times t)(x)=(2x+4)\times5x=10x^2+20x$

Which is a graph of an odd function?

Oksana_A [137]

The graph of an odd function has rotational symmetry about the origin, or at the point (0,0). That means we cut its graph along the y−axis and then reflect its even half in the x−axis first followed by the reflection in the y−axis. According to google about this information Answer should be image number 4

The physics department of a college has 8 male professors, 11 female professors, 16 male teaching assistants, and 6 female teach

Lera25 [3.4K]

To determine the probability that one or the other circumstances will occur, you will count the number of possible outcomes and divide it by all the possible outcomes.

#of female teaching assistants + # of male teaching assistants + # of female professors

6 + 16 + 11 = 33

Total = 41

33/41 = 80

There is a approximate 80% probability that one or the other will occur.
