Giovanni started a new job and decided to open a bank account with $10. Each week he will deposit $8 from his pay to the account. Which of the following recursive formulas can be used to model the total amount of money in Giovanni's account?

The right one will be Brainliest and be given 20 points

Answers

Answer 1

Answer:

an-1+8 where a1 =10

Step-by-step explanation:

Since 10 is the starting variable we know that a1 is 10.

Answer 2

The Recursive Formula is  [tex]a_n[/tex] = 10 + 8n.

What is Recursive Formula?

Any term of a series can be defined by its preceding term in a recursive formula (s).

For example: The recursive formula of an arithmetic sequence is, an = an-1 + d. The recursive formula of a geometric sequence is, an = an-1r.

Given:

Opening amount in bank= $10

Each week he will deposit $8.

On End of first week = 10+ 8= $18

On End of second week = 18 + 8= $26

On End of third week = 26+ 8= $34

Continuing this way we get

By end of n weeks, [tex]a_n[/tex] = 10 + 8n

Carlos wants to rent a car. For the particular car he wants, Gentle Rental charges $185 per week plus 25 cents per mile driven. Rental Giant charges a flat fee of $275 per week. What is the number of miles driven so that renting from Gentle Rental cost Carlos less than renting from Rental Giant?


A. Less than or equal to 360 miles

B. Less than 360 miles

C. Less than or equal to 115 miles

D. Less than 1,840

Answers

Answer:

B. Less than 360 miles

Step-by-step explanation:

Let the number of miles driven be [tex]x[/tex]

The cost of renting from Gentle Rental per week is

[tex]185+0.25x[/tex]

The cost of renting from Rental Giant per week is [tex]275[/tex].

Now we have to find after how many miles the cost of renting from Gentle Rental cost Carlos less than renting from Rental Giant

[tex]185+0.25x<275\\\Rightarrow 0.25x<275-180\\\Rightarrow x<\dfrac{90}{0.25}\\\Rightarrow x<360[/tex]

So, the answer is less than 360 miles.

The sum of the measures of two acute angles is always greater than 90 degrees

Answers

Answer:

One acute angle will always measure between 0° and 90° . Two acute angles can sum to be either greater than, less than, or equal to a right angle. Two acute angles can be complementary angles (adding to 90° ). Two acute angles alone cannot sum to make a straight angle (180° )

Answer:

(f + g)(3) = 9

Step-by-step explanation:

f(x) = x² + 1

g(x) = x - 4

Thus:

(f + g)(x) = (x² + 1) + (x - 4)

(f + g)(x) = x² + 1 + x - 4

(f + g)(x) = x² + x - 3

Therefore, to find (f + g)(3), plug in the value of 3 into the equation:

(f + g)(3) = (3)² + 3 - 3

(f + g)(3) = 9 + 3 - 3

(f + g)(3) = 9

f f(x) is a linear function, which statement must be true? f(x) has no constant term. f(x) has no x2-term. f(x) has no terms with a coefficient other than 1. f(x) has no x-term. Mark this and return

Answers

Answer:

f(x) has not x^2 term.

Step-by-step explanation:

Linear function is in the form of y=mx+b

In the linear function y=mx+b there is a constant term b

There is also an x term.

m is the slope of f(x). The value of 'm' can be any number.

If we have x^2 term in f(x) then it is quadratic function.

Linear function must always have x with exponent 1

True option is f(x) has not x^2 term.

Find the cosθ if an angle is in standard position and the point with coordinates (7,24) lies on the terminal side of an angle.

Answers

Answer:

0.28

Step-by-step explanation:

Angles in standard position are angles with the initial side on the positive x-axis.

Since (7,24) lies on the terminal side of an angle, hence the line passing through the origin and point (7, 24) forms an angle with the x axis.

The slope of the line passing through the origin (0, 0) and the point (7, 24) is given by:

[tex]slope(m)=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{24-0}{7-0}\\\\m=\frac{24}{7 }[/tex]

The angle θ between a straight line and the x axis is:

tanθ = m

where m is the slope of the line.

Let θ be the angle between the line with a slope of 24/7 and the x axis, therefore:

tanθ = 24 / 7

θ = tan⁻¹(24/7)

θ = 73.74°

cosθ = cos(73.74°) = 0.28

A bacteria culture grows with constant relative growth rate. The bacteria count was 1296 after 2 hours and 531441 after 6 hours. Answer the following questions. 1. What is the relative growth rate

Answers

Answer:

1)k=1.50408

2)=64

3)P(t)=64e^(1.50408t)

4)=118098

5)t=6.42 hrs

Step-by-step explanation:

CHECK THE COMPLETE QUESTION BELOW

A bacteria culture grows with constant relative growth rate. The bacteria count was 1296 after 2 hours and 531441 after 6 hours. Answer the following questions.

1. What is the relative growth rate?

2. What was the initial size of the culture?

3. Find an expression for the number of bacteria after t hours.

4. Find the number of cells after 5 hours.

5. When will the population reach 1000000?

To find relative growth rate, expression below can be used

P(t)= Po*e^(kt)

Where k= growth rate

Po= initial amount

t= time in hours

We were given The bacteria count as 1296 after 2 hours and 531441 after 6 hours. This can be expressed below as

P(2)= P(o)e^(2k)= 1296.........eqn(1)

P(6)= P(o)e^(6k)= 531441........eqn(2)

If we find the ratio of the two eqn we have

531441/1296 =[P(o)e^(6k)]/[P(o)e^(2k)]

410.0625= e^(4k)

If we take Ln of both side

ln 410.0625=ln(e^4k)

k=1.50408

1)= k=1.50408

2)

From P(2)= Po*e^(2k)= 1296

1296=Po × e^(2×1.50408)

1296= Po × e^(3.00816)

Po=1296/e^(3.00816)

=64

3) the expression is P(t)=64e^(1.50408t)

4). P(5)=64e^(1.50408×5)

=118098

5) P(t)= 1,000,000

1000000=64e^(1.50408t)

1000000/64 = 64e^(1.50408t)

Ln(15625)=ln[e^(1.50408t)]

9.657=e^(1.50408t)

t=6.42 hrs

A coin is tossed and a six-sided die numbered 1 through 6 is rolled. Find the probability of tossing a head and then rolling a number greater than 1.

Answers

Answer:

[tex]Probability = 0.4167[/tex]

Step-by-step explanation:

Given

A toss of coin and a roll of 6-sides die

Required

P(Head and Number greater than 1)

First, we list the sample space of the coin:

[tex]Sample\ Space = \{Head, Tail\}[/tex]

From the sample space above:

[tex]P(Head) = \frac{1}{2}[/tex]

Next, we list the sample space of the die:

[tex]Sample\ Space = \{1,2,3,4,5,6\}[/tex]

There are 5 outcomes greater than 1; i.e. 2,3,4,5 and 6.

So:

[tex]P(Outcome> 1) = \frac{5}{6}[/tex]

Lastly, the required probability is calculated as:

[tex]Probability = P(Head) \ and \ P(Outcome>1)[/tex]

Change and to *

[tex]Probability = P(Head) \ * \ P(Outcome>1)[/tex]

Substitute values for P(Head) and P(Outcome > 1)

[tex]Probability = \frac{1}{2} * \frac{5}{6}[/tex]

[tex]Probability = \frac{5}{12}[/tex]

[tex]Probability = 0.4167[/tex]
