Step-by-step explanation:

The sum of given polynomials is [tex]4g^2-4g^4+5g-3g^3+3[/tex].

Given polynomials are:

[tex]1)g^2-4g^4+5g+9\\\\2)-3g^3+3g^2-6[/tex]

A polynomial is an algebraic expression that constitutes monomials of the form ax^n where n is a whole number.

The sum of expressions is

[tex]g^2-4g^4+5g+9-3g^3+3g^2-6[/tex]

Now, add monomials having similar exponents, like if monomial is like [tex]g^2[/tex] add it with another monomial having a term [tex]g^2[/tex] and do the same for other monomials.

[tex]g^2 + 3g^2 -4g^4+5g-3g^3+9-6[/tex]

[tex]4g^2-4g^4+5g-3g^3+3[/tex]

Therefore, the sum of given polynomials is [tex]4g^2-4g^4+5g-3g^3+3[/tex].

Answer:

x = 60

Step-by-step explanation:

The sum of exterior angles in a rectangle is equal to 360

so to find the value of x we need to use all given values and write an equation:

x + 2x + x + 2x = 360 add like terms

6x = 360 divide both sides by 6

F. Butterfly population doubles each month

An exponential function is a function that grows exponentially.

Exponential functions have a multiplicative rate of change. This means each term can be multiplied by a specific number to get to the next.

Example of an exponential function:

1, 2, 4, 8, 16, 32, 64, 128, 256...

Knowing this, let's look at each example.

A.

The rocket grows at a rate of 45 m/s, but then goes back down. This is not an exponential function. This is most likely a quadratic function.

B.

Each term is being multiplied by 4. This is correct.

C.

This is too vague. We cannot determine what this is.

D.

This is a linear function. It has an additive rate of change; not a multiplicative one. This is wrong.

E.

Each term is 50% of the previous one. This is correct.

F.

The population is multiplied by 2 each month. This is correct.

Answer:

28 cm, 32cm , 36cm

Step-by-step explanation:

Given:

To Find:

Solution:

Let:

As, we know that,

★ Perimeter of Triangle = Sum of all sides ★

➝ 7x + 8x + 9x = 96cm

➝ 24x = 96cm

➮ x = 96/24

➮ x = 4

So, length of the sides are:

7x = 7 × 4 ➝ 28cm

8x = 8 × 4 ➝ 32cm

9x = 9 × 4 ➝ 36cm

Given :

To Find :

Solution :

Let us assume the sides be 7x cm, 8x cm and 9x cm.

We know,

[tex]\qquad{ \bold{ \pmb{Sum \: of \: all \: sides \: of \: the \: triangle = Perimeter_{(Triangle)}}}}

[/tex]

So, Substituting the values :

[tex]\qquad { \dashrightarrow{ \sf{7x + 8x + 9x = 96}}}[/tex]

[tex]\qquad { \dashrightarrow{ \sf{24x= 96}}}[/tex]

[tex]\qquad { \dashrightarrow{ \sf{ \dfrac{24x}{24} = \dfrac{96}{24} }}}[/tex]

[tex]\qquad { \dashrightarrow{ \bf{ x = 4 }}}[/tex]

Therefore,

The length of the sides of the triangle are :

[tex]\qquad { \dashrightarrow{ \sf{ 7x \: cm= 7 \times 4 \: cm = \bf \: 28 \: cm }}}[/tex]

[tex]\qquad { \dashrightarrow{ \sf{ 8x \: cm= 8 \times 4 \: cm = \bf \: 32 \: cm }}}[/tex]

Graph A is incorrect because that is a graph of a negative exponential function.

Graph B is incorrect because that is a graph of a square root function.

Graph C is incorrect because that is a graph of a positive exponential function.

Graph D is correct because linear functions are always straight lines. Linear functions have the base equation of y = mx + b . Because there is only one "x" value to the first power, the function increases by the same amount between each "x" value.

Step-by-step explanation:

A lateral surface area of a cube is 256 m2. Find its volume.

A cube is a three-dimensional shape that is made up of 6 congruent square faces.

Answer: If the lateral surface area of a cube is 256 m2, then its volume is 512 cubic meters.

The lateral area of a cube is the sum of areas of all side faces of the cube

Explanation:

The lateral surface area (LSA) of the cube = sum of areas of all 4 side faces.

Let the edge length of the cube be x.

LSA = x2 + x2 + x2 + x2 = 4x2

Given that, LSA of the cube is 256 m2

4x2 = 256

x2 = 256/4

x2 = 64

x = 8

Length of edge of the given cube is 8 m.

The volume of a cube is x3.

The volume of cube = x3 = 83 = 512 m3

Thus, the volume of the given cube is 512 m3.

The volume of the given cube is 512 m³.

The volume of a cube is defined as the total number of cubic units occupied by the cube completely. A cube is a three-dimensional solid figure, having 6 square faces. Volume is nothing but the total space occupied by an object.

Given that, the lateral surface area of a cube is 256 m cube.

We know that, the formula to find lateral surface area of a cube is 4a², where a is edge of a cube

Now, 4a²=256

a²=64

a=8 m

The formula to find the volume of a cube is a³, where a is edge of a cube.

Thus, volume of a cube =8³ =512 m³

Therefore, the volume of a cube is 512 m³.

Answer: $32 is the discount

Step-by-step explanation: i got it right

Answer:

128. It will take away 32$ from 160

Step-by-step explanation:

20% of 160 is 32. 160 - 32 = 128 which will be the cost of the pair of skates.

The lines L1 & L2 and the equations y = mx + n & y = px + q are illustrations of linear equations

This is a vertical line that passes through the x = 2

So, the equation of line L1 is x = 2

This is a horizontal line that passes through the y = 2

So, the equation of line L2 is y = 2

The line y = mx + n passes through points (6,3) and (0,0)

This means that n = 0 i.e. the y-intercept.

The value of m is calculated as follows:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

This gives

[tex]m = \frac{0- 3}{0 - 6}[/tex]

[tex]m = 0.5[/tex]

So, the values of m and n in y = mx + n are 0.5 and 0, respectively.

The line y = px + q passes through points (6,3) and (0,12)

This means that q = 12 i.e. the y-intercept.

The value of p is calculated as follows:

[tex]p = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

This gives

[tex]p = \frac{12- 3}{0 - 6}[/tex]

[tex]p = -1.5[/tex]

So, the values of p and q in y = px + q are -1.5 and 12, respectively.

The above region represent the upper region between y=mx +n, y=px+q and line L1

The letter in this region is letter H

The above region represent the lower region between y=mx +n, y=px+q and line L2

The letters in this region are letters A and E

Answer:

  x = -3 or 7

Step-by-step explanation:

The zero product property tells you a product will be zero if and only if a factor is zero. This property is used to find the zeros of polynomial functions by factoring them, then considering the variable values that make the factors zero. The zero of a monic linear binomial factor will be the opposite of the constant in that binomial.

__

The factored form of the given polynomial is ...

  y = (x -7)(x +3)

The values of x that make these factors zero are ...

  x -7 = 0   ⇒   x = 7

  x +3 = 0   ⇒   x = -3

The zeros of the polynomial function are x = -3, and x = 7.

The correct statement are statements B and C

Given the following equation for the distance of Bicyclist A expressed as:

d = 11.5h + 5

After 1 hour for A

d(1) = 11.5 + 5
d(1) = 16.5

For bicycle B, the distance traveled after 1 hour is 12.5 miles from the graph. Hence B is not traveling 1 mile per hour faster than A.

After 2 hours for A;

d(2) = 11.5(2) + 5

d(2) = 23 + 5 = 28 miles

Hence after 2 hours, A will have traveled a total of 28 miles.

From the graph, we can see that B started from the town (origin), and from the equation, A started from 5 miles from town (y-intercept is 5)
