What’s the value of a?

The correct option regarding the end behavior of p(x)=-9x^9+6x^6-3x^3+1 is given as follows:

B. As x -> -∞, f(x) -> ∞ and as x -> ∞, f(x) -> -∞.

The end behavior of a polynomial function is obtained by the limits of the function as x approaches infinity, meaning that only the term with the highest exponent is considered.

These limits are divided into two tails, as follows:

The function for this problem is defined as follows:

p(x)=-9x^9+6x^6-3x^3+1.

Hence the term with the highest exponent is:

-9x^9.

At the left tail of the graph, the end behavior is given as follows:

lim x -> -∞ f(x) =lim x -> -∞ -9x^9 = -9(-∞)^9 = -9 x (-∞) = ∞.

At the right tail of the graph, the end behavior is given as follows:

lim x -> ∞ f(x) =lim x -> ∞ -9x^9 = -9(∞)^9 = -9 x (∞) = -∞.

Hence option B is correct.

The problem is given by the image shown at the end of the answer.

Answer: 20

Step-by-step explanation:

5 boxes with 10, 10, 10, 10, and 10 donuts in each box.

She gives one box away, so that is 50-10=40

Then she gives 2 boxes away, which is 40-20=20, so she has 20 donuts left to share with her classmates.

Answer: 20

Step-by-step explanation:

5 x 10 = 50 Donuts

50 Donuts - 10       for the Bus driver

40 Donuts - 20      for the school principal

=20

She can share 20 Donuts with her classmates.

The inequality can be simplified to:

-7 < x < 3

And the graph can be seen in the image at the end.

Here we have the inequality:

|x + 2| + 1 > 6

To solve this, we need to isolate the variable x, so if we first subtract 1 we get:

|x + 2| +1 - 1 > 6 - 1

|x + 2| > 5

The absolute value part can be decomposed into two.

-5 < x + 2 < 5

Now we can subtract 2 in all the inequality, so we get:

-5 - 2 < x + 2 - 2 < 5 - 2

-7 < x < 3

The graph of this can be seen below

a. False, the slope of f(x) will be steeper than m(x).

b. False, the y-intercept of m(x) will be equal to f(x).

What is a slope?

Slope and slant both refer to an incline away from a reference surface or line that is generally straight. The definition of slope is "a vertical inclination in an oblique direction" Here, the land abruptly slopes either upward or downhill.

Here, we have

f(x) = x and m(x) = 3/5f(x)

a.  m₁ = slope of f(x) = x is 1

     m₂ = slope of m(x) = 3/5f(x) is 3/5

    m₁ >  m₂

f(x) = x is more steeper than m(x) = 3/5f(x).

b.  a₁ = intercept of f(x) = x is 0.

    b₁ = intercept of m(x) = 3/5f(x) is 0.

The y-intercept of m(x) will be equal to f(x).

Hence, a. False, the slope of f(x) will be steeper than m(x).

b. False, the y-intercept of m(x) will be equal to f(x).

The possible values of k that forms a triangle with an area of 1.5 square units are 1 and 2/3

A triangle is a three sided polygon.

The equation of the parabola is; y = 0.5•(x - 3)•(x + k)

The area of the triangle = 1.5 square units

A x-intercept of the equation, y = 0.5•(x - 3)•(x + k) is x = 3.

The area of a triangle, A, is found from the equation

A = 0.5 × Base length × Height

When x = 3, the height of the triangle is therefore;

A = 1.5 = 0.5 × 3 × Height

Height = 1.5 ÷ (0.5 × 3) = 1

Similarly, when the height is 3, the base length is 1

The y-intercept has a value of y = 0.5•(0 - 3)•(0 + k) = -1.5•k

Area of triangle = 0.5 × 1.5•k × k = 1.5

k = 1

When the x-intercept is 3, we have;

0.5 × 1.5•k × 3 = 1.5

k = 1/(1.5) = 2/3

If the system of equations, A·x + B·y = C and P·x + Q·y = R has infinitely many solutions, then the relationship between the values, A, B, C, P, Q, and R is; A/P = B/Q = C/R

A system of linear equations can have no solutions, only one solution or infinitely many solutions.

Part of the question that appear missing is presented as follows;

The system of equations in the question is;

If the system has infinitely many solutions, then the equations (1) and (2) represent the same equation, such that equation (1) can be obtained directly from equation (2) and vice versa

This indicates that equation (1) is a multiple of equation (2)

Let the common factor be c, we have;

Step-by-step explanation:

listen to guy above he opened my eyes

5725 is the height of the mountain prior to construction, represented by the variable h.

Two or more expressions with an Equal sign is called as Equation.

Given,

The mountain that contains Mount Rushmore is approximately 5,675 feet high.

The height of the mountain is 622.5 feet less than 1.1 times its height before construction began.

1.1h – 622.5 = 5,675 is the equation to find the height of the mountain prior to construction, represented by the variable h

1.1h – 622.5 = 5,675

We need to find the value of h

Add 622.5 on both the sides

1.1h=5675+622.5

1.1h=6297.5

Divide both sides by 1.1

h=6297.5/1.1

h=5725

Hence 5725 is the height of the mountain prior to construction, represented by the variable h.

The height of the school is 8.5 m.

For a project in his Geometry class, Jacob uses a mirror on the ground to measure the height of his school building.

To find out how tall is the school:

An image is always formed at the back of a mirror. Thus, the appropriate option is -8.75 m. The flagpole is 8.75 m tall.

Let the angle of depression from Madelyn's point of view be represented by θ. Then applying the required trigonometric function, we have;

Tan θ = [tex]\frac{opposite}{adjacent}[/tex]

         = [tex]\frac{1.65}{1.7}[/tex]

Tan θ = 0.9706

θ = [tex]Tan^{-1} 0.9706[/tex]

 = [tex]44.2^{o}[/tex]

θ = [tex]44.2^{o}[/tex]

Let the height of the flag be represented by h. And for a given mirror, the angle of incidence is equal to that of reflection. Then;

Tan θ = [tex]\frac{opposite}{adjacent}[/tex]

        = [tex]\frac{h}{8.75}[/tex]

0.9706 = [tex]\frac{h}{8.75}[/tex]

h = 0.9706 x 8.75

 = 8.49275

h = 8.5 m

Since the image is formed at the back of the mirror, then the flagpole is 8.5 m.

Hence the answer is the height of the school is 8.5 m.

Then the set function will be,

a) {(1,0), (1,1), (2,2), (2,2)}

→ The x values underlined are repeated.

Hence, it is not a set function.

b) {(0,0), (1,1), (1,1), (3,3)}

→ The x values underlined are repeated.

Hence, it is not a set function.

c) {(0,-2), (0,-1), (0,1), (0,2)}

→ The x values underlined are repeated.

d) {(-2,0), (-1,0), (1,0), (2,0)}

→ There are no repeated values for x.

Hence, it is a set function.

The probability that the number generated contains the digit 3 at least once is 0.7458.

Probability that there is digit 3 at least once =  1- P(no 3s in the number)

Total probability is, 10^13.

Here the digits are 0 to 9. we have 10 choices and the digits can be repeated hence the total probability is 10^13.

Now, if there is no 3, the choices will 9, hence the probability is 9^13.

Further, the probability of an event happening, is equal to the

favourable outcomes/total outcomes.

Hence, we get the probability of no 3's is 9^13/10^13

The value of the expression -15x+14y as calculated from the given equations is 12.

The pair of simultaneous equations are given as

-9x+8y=3............................1

6x-6y=-3

Now we will solve these equation by elimination method.

6x-6y=-3

or, 2x-2y=-3.......................2

Now multiplying equation 2 by 4 and adding to equation 1 we get:

-9x+8y=3

8x - 8y = -12

or, -x = -9

or, x = 9

Now we use this value of x to find the value of y

-9x + 8y = 3

or , -81 -3 = -8y

or, y = 10.5  

Hence the value of the expression -15x+14y is

=-15(9) + (14)(10.5)
