Answer
I believe it is 1/12
Step-by-step explanation:
as it is 24 ft tall, and then the model is 2 ft tall
22 ft is subtracted
so basically for every 12 ft one is added to the model
so 1/12 should be the ans

felixs total credit card balance is described by the following function f(p)=p(1.30). if felix owes 2500, what is the total bill plus interest
Given:
Felix's total credit card balance is described by the following function
[tex]f(p)=p(1.30)[/tex]
To find:
The total bill plus interest if Felix owes 2500.
Solution:
We have,
[tex]f(p)=p(1.30)[/tex]
Where [tex]p[/tex] is the amount Felix owes.
Putting [tex]p=2500[/tex] in the given function, we get
[tex]f(2500)=2500(1.30)[/tex]
[tex]f(2500)=3250[/tex]
Therefore, the total bill plus interest is 3250.
the percent change from 50 to 43

What are the values of the function when x=0 and when x=4?
Answer:
0 and h4
Step-by-step explanation:
Value of function when x=0 is 10 and at x=4 is 16.
What are the values of the function?The value of a function, given the value(s) allocated to its argument(s), exists as the quantity assumed by the function for these statement values.
Function value may direct to: In mathematics, the value of a function when involved in an argument.
Analyzing the piece wise function
when x is between 0(including) and 4(excluding), the function behaves as:
[tex]h(x)=2x^{2} -3x+10[/tex]
put x=0:
[tex]h(0)=2(0)^{2} -3(0)+10=10[/tex]
when x greater than equal to 4, the function behaves as:
[tex]h(x)=2^{x}[/tex]
put x=4:
[tex]h(4)=2^{4} =16[/tex]
Therefore, values are 10 and 16 respectively.

Answer:
Theta=60
Step-by-step explanation:
Lets start to get the value of x in [tex]sin(x)=\frac{1}{2}[/tex]
Just do the opposite which is [tex]sin^{-1}(\frac{1}{2}) = 30[/tex]
So [tex]sin(30)=\frac{1}{2}[/tex]
Still we got only the value of x not theta then
The value of x = theta/2
Theta/2=30 multiply each side by 2
Theta = 60
If θ is an angle in standard position whose terminal side lies in quadrant III and sin θ=-√3/2, find the exact value of the tan θ
Answer:
C) √3
tanθ = √3
Step-by-step explanation:
Step:-1
Given that θ be an angle in standard position whose terminal side
Given that the angle
sinθ = [tex]\frac{-\sqrt{3} }{2}[/tex]
Given that the Opposite side AB = [tex]\sqrt{3}[/tex]
Hypotensue AC = 2
Step(ii):-
By using Pythagoras theorem
AC² = AB² +BC²
BC² = AC² - AB²
BC² = 4 - (√3)²
= 4-3
BC = 1
Adjacent side(BC) = 1
Step(iiI):-
Given that 'θ' lies in the third quadrant so tanθ is positive
tanθ = [tex]\frac{AB}{BC} = \frac{\sqrt{3} }{1}[/tex]

What is the actual height of the building shown in the model?
Answer:
The actual height is 150ft
Step-by-step explanation:
Given
[tex]Width : Height = 2cm : 5cm[/tex]
[tex]Actual\ width = 60ft[/tex]
Required
Determine the actual height
Substitute 60ft for width in: [tex]Width : Height = 2cm : 5cm[/tex]
[tex]60ft:Height =2cm:5cm[/tex]
Express as fraction
[tex]\frac{60ft}{Height} =\frac{2cm}{5cm}[/tex]
[tex]\frac{60ft}{Height} =\frac{2}{5}[/tex]
Make height the subject
[tex]Height = \frac{5}{2} * 60ft[/tex]
[tex]Height = 5 * 30ft[/tex]
[tex]Height = 150ft[/tex]
Answer:
Step-by-step explanation:
1 cm represents 30 ft
height of building = 5 cm × 30 ft/cm = 150 ft

Indicate whether the function represents an exponential growth or decay.
Answer:
1) decay
2) growth
3) growth
Step-by-step explanation:
A generic exponential function can be written as:
f(x) = A*(r)^x
Where:
A is the initial amount of something.
r is the rate of growth.
x is the variable, usually, represents time.
if r > 1, we have an exponential growth.
if r < 1, we have an exponential decay.
1) f(x) = (3/4)^x
in this case we have:
A = 1
r = (3/4) = 0.75
Clearly, r < 1.
Then this is an exponential decay.
2) f(x) = (1/6)*4^x
In this case we have:
A = (1/6)
r = 4
Here we have r > 1.
Then this is an exponential growth.
3) f(x) = (1/4)*(5/2)^x
in this case we have:
A = 1/4
r = 5/2 = 2.5
here we have r > 1, then this is an exponential growth.
In a baseball card collection, 40% of the cards are worth more than $100. If 12 cards in the collection are worth more than $100, how many total baseball cards are in the collection?
Answer:
