Using arithmetic sequence concepts, it is found that the common difference of the sequence is of -7.

In this problem, the sequence is: {-8, -1, 6, 13}

The difference between consecutive terms is:

[tex]13 - 6 = 6 - (-1) = -1 - (-8) = 7[/tex]

Hence, the common difference of the sequence is of -7.

Answer: 0.628

Step-by-step explanation:

Probability of U.S. smartphone owners have made an effort to limit their phone use in the past : p = 0.4702

Sample size : n= 54

Mean : [tex]\mu =(54)(0.4702)=25.39[/tex]

Standard deviation:

[tex]\sigma=\sqrt{(54)(0.4702)}=\sqrt{25.39}\\\\\approx5.039[/tex]

The probability that between 22 and 29 (inclusively) will have attempted to limit their cell phone use in the past will be :

[tex]P(22\leq x\leq29)=P(21<x<30)=P(\dfrac{21-25.39}{5.039}<\dfrac{X-\mu}{\sigma}<\dfrac{30-25.39}{5.039})\\\\=P(-0.8712<z<0.914864)\ \ \ \ [z=\dfrac{X-\mu}{\sigma}]\\\\=P(z<0.914864)-P(z<-0.8712)\\\\=P(z<0.914864)-(1-P(z<0.8712))\\\\=0.8198685-(1-0.8081775)\ \ \ [\text{ By p-value table}]\\\\=0.628046[/tex]

Hence, the required probability = 0.628

Answer:

The actual height of telescope is 42.85 inches

Step-by-step explanation:

Given that:

Height of model of telescope = 15 inches

Diameter of model of telescope = 3.5 inches

Actual diameter of telescope = 10 inches

Actual height of telescope = x

Ratio of model's diameter to height :: Ratio of actual diameter to height

3.5 : 15 :: 10 : x

Product of extreme = Product of mean

3.5*x = 10*15

3.5x=150

Dividing both sides by 3.5

[tex]\frac{3.5x}{3.5}=\frac{150}{3.5}\\x=42.85[/tex]

Hence,

The actual height of telescope is 42.85 inches

Equation of the line

A straight line can be written in the form:

y = ax + b

Where a and b are constants and x is the independent variable.

The essential condition for an equation to be linear is that the x must be powered to the exponent 1, which is usually not written.

From the equations presented in the table:

[tex]y = x^1+2[/tex] is linear because the exponent of the x is 1

y = 5(x+2) = 5x + 10 is linear with a=5 and b=10.

y = x is linear with a=1 and b=0

[tex]y = x^2+1[/tex] is not linear because the exponent of x is 2

[tex]y = x(x) = x^2[/tex] is not linear because the exponent of x is 2

The table below summarizes the results

Answer:

x = 2, y = 9 or (2,9)

Step-by-step explanation:

Hello!

The first equation "y = 5x - 1" is telling us that y is equal to 5x - 1

We can plug in the first equation into the second like this:

2x + y = 13 (we know y so we can plug it in)

2x + (5x - 1) = 13

2x + 5x - 1 = 13

7x - 1 = 13

Now we add 1 to both sides

7x - 1 + 1 = 13 + 1

7x = 14

x = 2

Now we plug in x to find y:

y = 5x - 1

y = 5(2) - 1

y = 10 - 1

y = 9

Step-by-step explanation:

<B          adjacent              opposite                    hypoth

Answer:

(a) A = (20mg)/(2^(t/30))

(b) 12.6mg

(c) 129.6years

Step-by-step explanation:

To calculate the amount remaining after a number of half-lives, n, we can make use of:

[tex]A = \frac{B}{2^n}[/tex]

Where A = amount remaining

B = initial amount

[tex]n = \frac{t}{t_{0.5}}[/tex]

(a) A = (20mg)/(2^(t/30))

(b) Mass after 20years

A = (20mg)/(2^(20/30)) ≈ 12.6mg

(c) After how long will only 1mg remain:

1mg = (20mg)/(2^(t/30))

[tex]20mg = {2^{\frac{t}{30}}[/tex]

Taking log of both sides we have:

Log(20) = (t/30)log(2)

t/30 = (log(20))/(log(2)) ≈ 4.3

t/30 = 4.3

t = 30 x 4.3 ≈ 129.6years.

The change would you owe them is : 2.528

We have the following information available from the question is:

A customer purchase aced items in your store totaling $12.64.

They hand you three $5.00 bills.

We have to find the how much change would you owe them?

Now, According to the question:

The change would you owe them is :

Then, Divide the store totaling bill is $12.64 by $5.00 bills.

We get :

=> $12.64 ÷ %5.00

=> 2.528

Answer:

Step-by-step explanation:

The horizontal asymptote occurs at x = 0, Hence the equation that represents the asymptote of the graph is at x = 0

f(x) = 2^x +3.

0 = 2^x +3.

2^x +3. = 0

2^x = -3

log 2^ x = log(-3)

x log2 = log(-3)

x = log(-3)/log 2

Hence the required function is when x = 0

Answer:

t = 54m + 160

Step-by-step explanation:

Input = m

Output = t

Equation of the function in slope-intercept form, is represented as t = km + b

Where,

k = slope/rate of change

b = y-intercept

Using two pairs, say, (2, 268) and (3, 322):

[tex] slope(j) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{322 - 268}{3 - 2} = \frac{54}{1} = 54 [/tex]

k = 54

Find b, by substituting m = 2, t = 268, and k = 54 into t = km + b.

Thus:

268 = (54)(2) + b

268 = 108 + b

268 - 108 = b (subtraction property of equality)

160 = b

b = 160

To find the equation of the function, substitute k = 54, and b = 160 into t = km + b.

Thus:

t = 54m + 160
