Question 2 of 5
Select the correct answer.
Charlie and his friends are playing a game. They started round 1 of the game with 27 people. The
number of people in the first five
rounds is shown in the table.
Round
Number of People
1 27
2 25
3 23
4 21
5 19
What is the explicit function that can be used to determine the number of people remaining in the nth round?
Of(n) = -2n + 27
of(n) = -2n + 29
f(n) = 2n + 27
f(n) = 2n + 29

Answers

Answer 1
of(n) = -2n + 29

1. find the difference
25-27= -2
23-25= -2
...
that’s your first part of the equation (-2n...)

2. get your first term and do the inverse function

so because it’s -2, you’ll add 2 to your first term which is 27

27+2= 29

3. -2n + 29

Which of the q-values satisfy the following inequality?

6 - 3q ≤ 1

(Select all that apply)

q = 0

q = 1

q = 2

Answers

Answer:

q = 2

Step-by-step explanation:

simply plug in q as the numbers listed. examples:

6 - 3(0) ≤ 1

6 - 0 ≤ 1

6 ≤ 1

not true. 6 is greater than 1. asking for less than or equal to 1.

6 - 3(1) ≤ 1

6 - 3 ≤ 1

3 ≤ 1

not true, 3 is greater than 1. asking for less than or equal to 1.

6 - 3(2) ≤ 1

6 - 6 ≤ 1

0 ≤ 1

true. 0 is less than 1.

q=0,1,2 all are valid values for the given inequality.

What is an inequality?

An inequality is an inequation separated by <,>≥,≤. The relationship between two values that are not equal is defined by inequalities. Inequality means not equal. Generally, if two values are not equal, we use “not equal symbol (≠)”.

Given here: The inequality 6-3q≤1

 Now simplifying the inequality

6-3q≤1

Substracting by -3 on both sides we get

6-3q-6≤1-6

-3q≤-5

Now multiplying both sides by -1/3 we get

q≥-5/3

or q≥-1.666

Therefore q=0, q=1,q=2 all satisfy the inequality q≥-5/3

Hence, q=0,1,2 all satisfy the inequality and they are all valid values.

The answer is J.

Step-by-step explanation:

Pythagorean Theorem: c² = a² + b²

The longest side appears to be 5 feet, which we can plug into the equation.

5² = a² + b²

Next, we can see that another side has already been shown, the 3 feet, so let's plug that in too.

5² = a² + 3²

25 = a² + 9

-9 -9

16 = a²

√16 = 4

We have now figured out the bottom of one triangle, but there is still another triangle that needs to be solved.

We can simply just add 4 + 4 together, which equals 8 feet, and is the width of the bottom of the tent.

What is the equation of a line that passes through the points (0, 5) and (4, 8)? Write your answer in slope-intercept form (y = mx + b). ( help pleaseee )

Answers

This will need become a point slope form.

First we need to find slope

(Y2-Y1/X2-X1)

(8-5/4-0) = (3/4)

Slope = (3/4)

Now for the point slope equation

y - y1 = m(x-x1)

Plug in one of the points and the slope

y - (5) = 3/4(x - (0))

Let’s convert to y = mx + b formatting

y - (5) = 3/4(x - (0))

y - 5 = 3/4x - (3/4)(0)

y - 5 = 3/4x

y = 3/4x + 5

This will be your equation.

The median of a data-set is the value that separates the bottom 50% from the upper 50% of values.

In this problem, there are 7 values, which is an odd number, hence the median is the (7+1)/2 = 4th number in the ordered set, which is of 17 kg.

x = 24

obtuse isosceles triangle

Step-by-step explanation:

x = 24 because a triangle has to have all the angles add up to 180. So x + x +132 = 180.

180-132 = 2x

48 = 2x

x = 24

It is an isosceles because two of the angles are the same and one is different which means two of the sides are the same and one is different. (isosceles = icicle is how I remember it). Obtuse because there is an angle that is over 90 degrees.

x=24
