Answer:
x = 7√3, y = 14x = √3, y = 3Step-by-step explanation:
Use the property of 30-60-90 degree right triangles
They have the ratio of sides from smallest to greatest: 1: √3 : 2
The top triangle
y = 2*7 = 14x = 7√3The bottom triangle
Acute angles n and 2n makes them 30° and 60°
x = 1/2*2√3 = √3y = √3*√3 = 3Answer:
x = 1/2*2√3 = √3
y = √3*√3 = 3

Find the value of x in each diagram.
Answers
Answer:
4. 25 5. 80 6. 30
Step-by-step explanation:
All triangles add up to 180.
The triangle in #4 is right, so 90° + 65° = 155°
180° - 155° = 25°
x=25
#5.
50° + 50° = 100°
180° - 100° = 80°
x=80
In #4 the triangle is an equilateral, so all the angles will be equal. 2x + 2x + 2x = 180
6x = 180
x = 30
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180°
Two of the angle measures are given in each triangle so to find the third angle measurement we need to subtract the sum of two of the interior angles
4.
180 - (65 + 90) = x
180 - 155 = x
25 = x
5.
180 - (50+5) = x
180 - 100 = x
80 = x
For the 6th question all side lengths are equal so the angle measures also equal and 60 each
2x = 60
x = 30
Indicate whether the function represents an exponential growth or decay.
Answers
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.

What is the actual height of the building shown in the model?
Answers
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

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
Answers
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.
