A baseball card that was valued at $200 in 1980 has increased in value by 7% each year. Write a function to model this situation, then find the value of the card in 2016

Answers

Answer 1

Answer:

$2284.6

Step-by-step explanation:

Given data

Principal= $200

Rate= 7%

Time= 1980-2016= 36 years

The expression for the exponential model is given as

A= P(b)^t

b=1+r-----------because will are dealing with increase

A= P(1+r)^t

A=200(1+0.07)^36

A= 200(1.07)^36

A= 200*11.423

A=$2284.6

The value of the card is $2284.6

Answers

Answer: 195,944 bicycles

Step-by-step explanation:

First find the number of bicycles sold in August.

August sales - July sales - 9,152

= 61,753 - 9,152

= 52,601 bicycles

The number of bicycles sold in 3 months is:

= June sales + July + August ,

= 81,590 + 61,753 + 52,601

= 195,944 bicycles

a ladder reaches the top of a 20 foot building. the ladder is 4.5 feet away from the building. how long is the ladder?

a 24.5 feet
b 19.5 feet
c 20.5 feet
d 3.5 feet

Answers

Answer:

C

Step-by-step explanation:

do that with pithagoras:

20² + 4,5² = x²

400 + 20,25 = x²

420,25 = x²

x = [tex]\sqrt{420,25}[/tex]

x ~ 20,5

Letter C: 20,5 feet

The required length of the ladder is given as 20.5 feet. Option C is correct.

What are Pythagorean triplets?  

In a right-angled triangle, its side, such as the hypotenuse, is perpendicular, and the base is Pythagorean triplets.

Here,
The height of the building is 20 feet,
base length from the bottom of the building to the bottom of the ladder is 4.5 feet,
Let the hypotenuse length of the ladder be x,
Applying the Pythagoras theorem,
x² = 4.5² + 20²
x = √[420.25]
x = 20.5 feet

Thus, the required length of the ladder is given as 20.5 feet. Option C is correct.

Has photo ❤️

Answers

Answer:

18.84feet

Step-by-step explanation:

Length of an arc = rtheta

radius r = 9feet

theta = SR= 120°

Convert theta to radians

theta = 120π/180

theta= 2π/3

Length of the arc = 9 * 2π/3

L = 18π/3

L = 6π

L = 6(3.14)

L = 18.84feet

Hence the length of the arc is 18.84feet

A25 = 120

Step-by-step explanation:

Given sequence;

6 , 11 , 16 , 21 , 26 , .......

Find:

25th term

Computation:

First term of AP (a) = 6

Common difference (d) = a2 - a1

Common difference (d) = 11 - 6

Common difference (d) = 5

An = a + (n-1)d

So,

An = 6 + (n-1)5

So,

If n = 25

A25 = 6 + (25 - 1)5

A25 = 6 + (24)5

A25 = 6 + 120

A25 = 120

find x for f (x) = 13

Answers

Answer:

The required value of [tex]x[/tex] is [tex]\frac{3}{5}[/tex]

Step-by-step explanation:

Given,

f (2) = 60 – 5

      = (30 X 2) - 5

∴ f (x) = [tex]30x-5[/tex]

Again,

f (x) = 13 [given]

[tex]30x-5=13\\or, 30x= 13+5\\or, 30x=18\\or, x=\frac{18}{30} \\\\or, x=\frac{3}{5} \\[/tex]

∴[tex]x=\frac{3}{5}[/tex]

Verification:

f (x) = [tex]30x-5[/tex]

∴ f ([tex]\frac{3}{5}[/tex]) = (30 X [tex]\frac{3}{5}[/tex]) - 5

         = 18 - 5

         = 13

∴ The required value of [tex]x[/tex] is [tex]\frac{3}{5}[/tex]
