Determine if the sequence is arithmetic or geometric, and find the common difference or ratio.


x 1 2 3 4
f(x) 5 −5 −15 −25
Arithmetic, common difference = −10
Arithmetic, common difference = −1
Geometric, common ratio = −10
Geometric, common ratio = −1

Answers

Answer 1

Answer:

The correct option is;

Arithmetic, common difference = -10

Step-by-step explanation:

The x terms given of the sequence are;

x         [tex]{}[/tex]  1          2         3         4      

f(x)      [tex]{}[/tex]   5        -5       -15        -25

For a geometric progression, a·r/a = a·r²/ar = ar³/ar² = (n + 1)/n = r

We check to obtain -5/5 ≠ -15/(-5), therefore, the system is not a geometric progression

For ab arithmetic progression, we have;

(n + 1)th term - nth term = (n + 2)th term - (n + 1)th term = d (The common difference

We check to obtain -5 - 5 10, -15 - (-5) = -15 + 5 = -10 similarly, we have; -25 - (-15) = -25 + 15 = -10

Therefore, the sequence is an arithmetic sequence, with common difference = -10.

f(-2) = 5

Step-by-step explanation:

Step 1: Define

Decrease $820 by 32%​

Answers

Answer:

557.6

Step-by-step explanation:

Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

32% = 32/100 = 32 ÷ 100 = 0.32.

100% = 100/100 = 100 ÷ 100 = 1.

Percentage decrease = 32% × 820

New value =

820 - Percentage decrease =

820 - (32% × 820) =

820 - 32% × 820 =

(1 - 32%) × 820 =

(100% - 32%) × 820 =

68% × 820 =

A young sumo wrestler decided to go on a special high − -protein diet to gain weight rapidly. After  1 1 11 months, he weighed  1 4 0 k i l o g r a m s . 140 kilograms. He gained weight at a rate of  5 . 5 k i l o g r a m s 5.5 kilograms per month. Let  y y represent the sumo wrestlers weight ( i n k i l o g r a m s ) (in kilograms) after x months. Whats the y-intercept?

Answers

Given:

After 11 months, sumo wrestler weighed 140 kilograms.

He gained weight at a rate of 5.5 kilograms per month.

To find:

The y-intercept of the equation which represents y the  sumo  wrestlers  weight (in kilograms)  after x  months.

Solution:

Let y represent the sumo wrestlers weight (in kilograms) after x months.  

It is given that he gained  weight at a rate of  5.5 kilograms per month.

So, slope of the line is 5.5.

After  11  months,  sumo  wrestler weighed  140 kilograms. It means the line passes through the point (11,140).

The point slope form of the line is

[tex]y-y_1=m(x-x_1)[/tex]

where, m is slope of the line.

[tex]y-140=5.5(x-11)[/tex]

[tex]y-140=5.5x-60.5[/tex]

Add 140 on both sides.

[tex]y-140+140=5.5x-60.5+140[/tex]

[tex]y=5.5x+79.5[/tex]

Therefore, the required equation is [tex]y=5.5x+79.5[/tex].

Substitute x=0, to find the y-intercept of this equation.

[tex]y=5.5(0)+79.5[/tex]

[tex]y=79.5[/tex]

Therefore, the y-intercept is 79.5. It means initial weight of sumo is 79.5 kilograms.

Waich of the following is a true statement about perpendicular lines?

B. Perpendicular lines can also be parallel lines.
C. Perpendicular lines cannot be parallel to each other.
D. Perpendicular lines intersect in at least two points.

Answers

Answer:

C

Step-by-step explanation:

perpendicular lines intersect at a 90 degree angle, meaning it is not answer choice A.

B is incorrect because perpendicular lines intersect, so they can not be parallel.

C is correct because parallel lines never intersect, so perpendicular lines can never be parallel to each other.

D is incorrect because perpendicular lines only intersect at one point and create four consistent right angles.

Find 3 consecutive odd integers such that 1 less than 3 times the larger is equal to the sum of twice the first and twice the second number. Please explain why and with steps.

Answers

Answer:

7, 9, 11

Step-by-step explanation:

If x is the smallest of the integers, then x+2 is the next consecutive odd integer, and x+4 is the largest odd integer.

1 less than 3 times the largest is equal to the sum of twice the first and twice the second.

3(x+4) − 1 = 2x + 2(x+2)

3x + 12 − 1  = 2x + 2x + 4

3x + 11 = 4x + 4

7 = x

. Three out of four students in school have at least one sibling. If there are 300 students in your school, how many would have at least one sibling?

Answers

Answer: 225 students would have at least one sibling.

Step-by-step explanation:

Three out of four is the same as  3/4 meaning that if there are 300 students in your school then 3/4 times 300 will give the number of students with at least one sibling.  

3/4 * 300 = 225  

This means 225 students would have at least one sibling.

it would be 225

.75 x 300 = 225

Which linear equation has a slope of 3 and a y-intercept of -2?
y = 3x + 2
y=3x-2
y=-2x + 3
y = -2x - 3

Answers

Answer:

y=3x-2

Step-by-step explanation:

3 is the coefficient of x (slope)

-2 comes after (y-int)

linear equation y = 3x-2 has a slope of 3 and a y-intercept of -2.

What is the Slope of a line?

A line's slope can be determined by looking at its slope. The slope is determined mathematically as "increase over run" (change in y divided by change in x). There are several ways to find the slope, including standard form, slope-intercept form, and point-intercept form.

Given, A linear equation that has a slope of 3 and a  y-intercept of -2.

Y-intercept of -2 means at x = 0 y would be -2

The slope-intercept form of a line is

y = mx + c

where m = slope

c = constant

Substituting the values in the given equation

-2 = 0 * 3 + c

c = -2

thus, the equation of the line,

y = 3x -2

therefore, The y-intercept of the linear equation y = 3x-2 is -2, and its slope is 3.

Answer:

[tex]x = \frac{21}{2}[/tex]

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5x − 3(x+9) + 10 = 4

5x + (−3)(x) + (−3)(9) + 10 = 4 (Distribute)

5x + −3x + −27 + 10 = 4

(5x+−3x) + (−27+10) = 4 (Combine Like Terms)

2x + −17 = 4

2x − 17 = 4

Step 2: Add 17 to both sides.

2x − 17 + 17 = 4 + 17

2x = 21

Step 3: Divide both sides by 2.

[tex]\frac{2x}{2} = \frac{21}{2}[/tex]

[tex]x =\frac{21}{2}[/tex]
