Consider the first four terms of the sequence below.
-3, -12,-48,-192, ...
What is the 8th term of this sequence?

A.) -42,152
B.) -768
C.) -12,288
D.) -196,608

Answers

Answer: -49,152

Step-by-step explanation

r =4  -192/-48, -48/12

8th term= -3*4^7                 =-3*16384                 =-49,152

The first four terms of the sequence below ; -3, -12,-48,-192, ...therefore, the 8th term of this sequence is -49,152.

What is a geometric sequence and how to find its nth terms?

Suppose the initial term of a geometric sequence is a and the term by which we multiply the previous term to get the next term is r

Then the sequence would look like

[tex]a, ar, ar^2, ar^3, \cdots[/tex]

Thus, the nth term of such sequence would be  [tex]T_n = ar^{n-1}[/tex](you can easily predict this formula, as for nth term, the multiple r would've multiplied with initial terms n-1 times).

The first four terms of the sequence below.

-3, -12,-48,-192, ...

We need to find the 8th term of this sequence

r = 4 = -192/-48, -48/12

8th term = -3 x 4^7                

        = -3 x 16384                

        = -49,152

What is the slope-intercept form of a line that contains the point (0,3) and a slope=-2

PLZ HELPP

Answers

Answer:

C. y = -2x + 3

Step-by-step explanation:

The equation of a line in slope-intercept form is given as y = mx + b.

m = slope, while b = y-intercept.

We already know that the slope, m, = -2.

We are given a point also as (0, 3). This means, at x = 0, y = 3.

Therefore, the y-intercept, b, = 3, because, the line would intercept the y-axis of the graph at y = 3, and at that point, x = 0.

Thus,

Slope (m) = -2,

y-intercept (b) = 3

Plug these values into y = mx + b

✅The equation of the line in slope-intercept form would be:

y = -2x + 3

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The expression is,

⇒ √(x + 3) + 4 = 5

Now, We can solve the expression for x as;

⇒ √(x + 3) + 4 = 5

Subtract 4 both side, we get;

⇒ √(x + 3) + 4 - 4 = 5 - 4

⇒ √(x + 3) = 1

Taking square both side,

⇒ (√(x + 3))² = 1²

⇒ x + 3 = 1

Subtract 3 both side,

⇒ x + 3 - 3 = 1 - 3

⇒ x = - 2

A university president proposed that all students must take a course in ethics as a requirement for graduation. Three hundred faculty members and students were asked about their opinion on this issue. Find the probability that if one person is selected at random, from these 300 persons, this person is a faculty member or is in favor of this proposal.

Answers

You did not add the attachment for this question to be answered. I have added it

Answer:

0.5333

Step-by-step explanation:

We have

P(faculty) to be the probability of faculty being selected

= 70/300

= 0.233333333

We also have

P(favor) to be the probability of being in favor of this proposal

= 135/300

= 0.45

In answer to this question,

The required probability

= P(faculty) + p(favor) - p(faculty n favor)

p(faculty n favor) = 45/300

= 0.15

Probability = 0.233333333 + 0.45- 0.15

= 0.5333 approximately

Each Christmas elf makes x toys in an hour. n elves work for t hours to produce 1000 toys.

Write an equation that relates x, n, and t.

Answers

Answer:

e(X x T)=1000

Step-by-step explanation:

You do the number of toys they make(X) times the hours they work(T). Then multiply all of it by the number of elves(e). All of that equals the 1000 toys they make all together.

Equation relates x, n and t is n × x × t = 1000

What is  an equation?

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Each elf makes x toys in an hour

one elf will make x × t toys in t hours

n elf will make 1000 toys in t hours

So n elf will make 1000 toys in t hours

n × x × t = 1000

Hence, the equation relate x, n and t is n × x × t = 1000
