Answer 1

Answer:

a) aₙ = 6(n - 1), a₂₄ = 138b) aₙ = 2n + 1, a₂₄ = 49

===============================

Sequence a)

Ignoring the hexagon in the middle, we'll count the number of squares:

0, 6, 12, ...

This is an AP with the first term of a₁ = 0 and common difference of d = 6.

Explicit formula for an AP is:

aₙ = a₁ + (n - 1)d

Substitute the first term a₁ and common difference d into equation:

aₙ = 0 + (n - 1)*6aₙ = 6(n - 1)

The 24th term is:

a₂₄ = 6(24 - 1) = 6(23) = 138

Sequence b)

Count the number of circles:

3, 5, 7, ...

This is an AP with the first term of a₁ = 3 and common difference of d = 2.

The explicit formula for this AP is:

aₙ = 3 + (n - 1)*2aₙ = 3 + 2n - 2aₙ = 2n + 1

The 24th term is:

a₂₄ = 2*24 + 1 = 49

People who are illegally parked in downtown Orlando may be issued $15 or $20 parking
tickets. At the end of the week, Officer Bob had issued 41 parking tickets that totaled
$655 in fines. How many $15 tickets and how many $20 tickets did Officer Bob write?

Answers

Answer:

$15 tickets - 33, $20 tickets - 8

=================================

Let the number of $15 tickets is x and numbers of $20 tickets is y.

Set the system according to given information:

x  + y = 4115x + 20y = 655

Solve by elimination, multiply the first equation by 20 and subtract the second equation:

20x + 20y - 15x - 20y = 41*20 - 6555x = 165x = 165/5x = 33

Find y:

33 + y = 41y = 41 - 33y = 8

What is the formula of exponential growth?

"[tex]f(x)=ab^x[/tex],

where a is the initial value

b is the growth rate

x is time. "

For given question,

Suppose the function for the population growth is,

[tex]A(t)=A_0\times b^t[/tex]                         .........(1)

For t = 13, the population growth of virus would be,

[tex]\Rightarrow A(13)=A_0\times b^{13}[/tex]                  ..........(2)

But we have been given that a virus takes 13 days to double its original population.

[tex]\Rightarrow A(13)=2\times A_0[/tex]                      .........(3)

From (2) and (3),

[tex]\Rightarrow A_0\times b^{13}=2\times A_0\\\\\Rightarrow b^{13}=2\\\\\Rightarrow b=1.0548[/tex]

We need to find the number of days  to triple its original population

[tex]\Rightarrow A(t)=3\times A_0[/tex]                   ...........(4)

From (1) and (4),

[tex]\Rightarrow A_0\times b^t=A_0 \times 3\\\\\Rightarrow (1.0548)^t=3\\\\\Rightarrow t=20.6[/tex]

Therefore, a virus takes approximately 20.6 days to triple its original population

How many years will it take an initial investment of $25,000 to triple to $75,000 at an annual rate of 7% compounded continuously

Answers

Answer:

[tex]t = 15.7[/tex]

Step-by-step explanation:

Given

[tex]Principal = 25000[/tex] --- P

[tex]Amount = 75000[/tex] --- A

[tex]Rate = 7\%[/tex] --- R

Required

Determine the time (t)

Using continuous growth formula:

We have

[tex]A = Pe^{rt}[/tex]

Convert rate to decimal

[tex]Rate = 7\%[/tex]

[tex]r = 0.07[/tex]

Substitute values for A, P and r

[tex]75000 = 25000 * e^{0.07t}[/tex]

Divide both sides by 25000

[tex]3 = e^{0.07t}[/tex]

Rewrite the exponential function as logarithmic, we have:

[tex]ln3 = 0.07t[/tex]

Reorder

[tex]0.07t = ln3[/tex]

Divide both sides by 0.07

[tex]t = \frac{ln3}{0.07}[/tex]

[tex]t = \frac{1.09861228867}{0.07}[/tex]

[tex]t = 15.69[/tex]

[tex]t = 15.7[/tex]

Hence, the time is approximately 15.7 years

y=−1/7

for the picture is y=-57/7

Step-by-step explanation:

1. 8= -7y +7

Switch:sides

-7y+7=8

subtract 7 from both sides

-7y=1

divide both sides by -7

y=−1/7

2.so for 8/y+7=-7

multiply both sides by (y+7)

8/y+7(y+7)=-7(y+7)

simplify 8=-7(y+7)

flip

-7(y+7)=8

divide both sides by -7

y+7=-8/7

subtract 7 from both sides

and simplify

y=-57/7

The awnser is Y=-1/7

The value of x from the equation is  2√2

What are linear equations?

Linear equations are equations with one or two variables.

It is also important to note that the highest power of variable is 1

Given the equation;

yx² = 8y

Let's make 'x' the subject of the equation

Divide both sides by y, we have;

yx²/y = 8y/ y

x² = 8

Take the square root of both sides

(√x²) = √8

The square root takes the square, we have

x = √8

x = √4 × 2

x = 2√2

Thus, the value of x from the equation is  2√2

There are 48 minnows in the aquarium and there are 18 clownfish in aquarium

Given that in an aquarium ratio of minnows and clown fish is 8:3 and the ratio of clownfish and goldfish are in ratio 6:11 and there are 33 gold fishes in the aquarium.

⇒[tex]\frac{6}{11} =\frac{x}{33}[/tex] ( Here x is the number of clownfish)

⇒x=6×3

⇒x=18

Therefore, The number of clownfish in the aquarium is 18

Now,[tex]\frac{8}{3} =\frac{y}{18}[/tex](Here, y is the number of minnows in an aquarium)

⇒y=8×6

⇒y=48

Therefore, The number of minnows in the aquarium is 48

Therefore,The number of minnows in the aquarium is 48 and The number of clownfish in the aquarium is 18
