A linear function is one that has one or two variables and no exponents, according to the definition given in mathematics. It is a graphing function that produces a straight line.

To finish the graph, use a straightedge to draw a line through the two points as two points decide a line. The formula for a linear function is f(x)=mx+b, where m and b are real values representing the slope. Set f(x)=0 and work out the value of x to determine the x-intercept, if one exists. We can use y and f(x) interchangeably because y=f(x).

Answer: The common ratio of the geometric sequence is 1/2, the first term is -72, and the 4th term is -9.

Step-by-step explanation: The common ratio r of a geometric sequence is found by dividing the second term by the first term, and the nth term of the geometric sequence is given by a1 * r^(n-1), where a1 is the first term.

To find the common ratio r of this geometric sequence, we can use the fact that the 3rd term is -18 and the 6th term is 9216:

-18 = a1 * r^2

9216 = a1 * r^5

Dividing these two equations, we get:

-18/9216 = (a1 * r^2) / (a1 * r^5)

-18/9216 = r^-3

r = (-18/9216)^(-1/3)

Since r is the common ratio, it must be positive. Since (-18/9216)^(-1/3) is negative, we must take the positive root:

r = ((-18/9216)^(-1/3))^(1/3)

r = ((-18/9216)^(1/9))

r = (9216/-18)^(1/9)

r = (-512)^(1/9)

r = (-8)^(1/9)

r = (-2)^(2/9)

r = (-2)^(2/3)

r = (1/4)^(2/3)

r = 1/2

To find the first term a1, we can use the fact that the 3rd term is -18 and the common ratio is 1/2:

-18 = a1 * (1/2)^2

-18 = a1/4

a1 = -72

To find the 4th term a4, we can use the fact that the first term is -72 and the common ratio is 1/2:

a4 = (-72) * (1/2)^3

a4 = -9

Therefore, the common ratio of the geometric sequence is 1/2, the first term is -72, and the 4th term is -9.

Answer: I believe 140

Step-by-step explanation: This is how I found my answer:

420 / 3

= 140

420-140

=  280

420= number of all tickets sold.

140= number of adult tickets sold

280= number of student tickets sold

You might wonder how I know why it's 140. I know it's 140, because using my context clues, it stated:

"the number of student tickets sold was three times the number of adult tickets."

So, the one that was the bigger amount must be the student's tickets sold, while the lower amount has to be the adult's tickets sold. I hope this helped!

Answer:

m angle B = 27.54 degree

m angle C = 60.85 degree

Step-by-step explanation:

angle A is 90º so the other two angles must sum to 90º

2x+5x-8=90

7x-6=90

7x=96

x=13.77

therefore,

m angle B = 27.54 degree

m angle C = 60.85 degree

The inequality that is used to find the domain of the function would be B x - 3 ≥ 0

The domain of a function is defined as the set of all the possible input values that are valid for the given function.

The given function is f(x) = √x - 3

Here we have to find the inequality that is used to find the domain of the function.

Therefore, the function (x - 3) must be greater than or equal to 0

That is;

x - 3 ≥ 0

We will use the above inequality to find the domain of the function.

When we solve the above inequality, we get the domain of the function then;

x - 3≥0

Now add 3 on both sides, we get;

x - 3 + 3 ≥ 0 + 3

x ≥ 3

Therefore,  the answer is x - 3 ≥ 0

The required angles  ∠TBS and ∠TCV are 48° and 22° respectively.

A right-angled triangle is a kind of triangle that has one of its points equivalent to 90 degrees. The other two points summarize to 90 degrees. The sides that incorporate the right point are opposite and the foundation of the triangle. The third side is known as the hypotenuse, which is the longest side of each of the three sides

∠TBV = 24°

∠VBS = 24°

So, ∠TBS = (24° ) = 48°

And,

∠SAU = 92°,

So,

∠VAU = 46°

What is a angle bisector?

In geometry, an angle bisector is a line that divides an angle into two equal angles. The term "bisector" refers to a device that divides an object or a shape into two equal halves. An angle bisector is a ray that divides an angle into two identical segments of the same length.

As given in question:

AV , BV and CV are the angle bisector of ΔABC

UV = 17, BV = 18

∠SAU =92° and ∠TBV = 24°

Now,

∠TBV = ∠SBV = 24° ( BV is angle bisector)

So, ∠TBS = ∠TBV + ∠SBV

      ∠TBS = 24° + 24° = 48°

SV = UV = 17 (V is the incenter of ΔABC.)

∠SAU + ∠TBS + ∠TCU = 180° (Sum of angles of a triangle)

92° + 48° + ∠TCU = 180°

∠TCU = 180° - 140°

∠TCU = 40°

In linear equation,   20x + 45y = 440 ,     y = 2x  Where x is the number of small boxes sent and y  is the number of large boxes sent.

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.

                                  Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

Let be x the number of small boxes sent and y the number of large boxes sent.

Since each small box can hold 20 books (20x), each large box can hold 45 books (45y)and altogether can hold a total of 440 books, we can write the following equation to represent this

Step-by-step explanation:

Part a: Time taken to double the population of chipmunks is 5/2 months.

Part b: Population at population size; P = 200 is 50.

Part a: Time taken to double the population of chipmunks;

P(t) = 100[1 + (0.3)t + (0.04)t²].

P(0) = 100[1 + 0 + 0] = 100

P(t) = 200 = 100 + 30t + 4t²

4t² + 30t − 100 = 0

2t² + 15t − 50 = 0

(2t − 5)(t + 10) = 0

t = 5/2

It will take 5/2 months population to double its initial size P(0).

Part b: Population at population size; P=200

P'(t) = 0 + 30 + 8t

P = 200 when t = 5/2

P'(200) = 30 + 8(5/2)

P'(200) = 30 + 20

P'(200) = 50

Thus, the instantaneous rate of growth of the population when the population size is P=200 is 50.
