Answer:
f(3) = 68
Step-by-step explanation:
Given:
[tex]\sf f(1)=2[/tex]
[tex]\sf f(n) = f(n-1)^2+4[/tex]
[tex]\sf \implies f(2) = f(1)^2+4[/tex]
[tex]\sf \implies f(2) = 2^2+4=8[/tex]
[tex]\sf \implies f(3) = f(2)^2+4[/tex]
[tex]\sf \implies f(3) = 8^2+4=68[/tex]

An awning that covers a sliding glass door that is 88 inches tall forms an angle of 50° with the wall. The purpose of the awning is to prevent sunlight from entering the house when the angle of elevation of the sun is more than X = 60°
The length of awning which covers a sliding glass door that is 88 inches tall forms an angle of 50° with the wall, is 44.7 inches.
What is the law of sine?The law of sine is nothing but the relationship between the sides of the triangle to the angle of the triangle (oblique triangle).
It can be given as,
[tex]\dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}[/tex]
Here (A,B,C) are the angle of the triangle and (a,b,c) are the sides of that triangle.
An awning that covers a sliding glass door that is 88 inches tall forms an angle of 50° with the wall.
The figure of the problem is attached below. The length of AB which is L has to be find out.
The purpose of the awning is to prevent sunlight from entering the house when the angle of elevation of the sun is more than X = 60°. Thus, the angle ABC is 30 degrees.
[tex]AB=90-60\\AB=30^o[/tex]
The sum of all the interior angle is 180 degree. Thus, the angle ACB is,
[tex]\angle ACB=180-50-30\\\angle ACB=100^o\\[/tex]
Let suppose, the length of AB is a. Thus, by the sine law,
[tex]\dfrac{\sin 30}{a}=\dfrac{\sin 100}{88}\\a=\dfrac{88\times\sin 300}{\sin 100}\\a=447\rm\; in[/tex]
Thus, the length of awning which covers a sliding glass door that is 88 inches tall forms an angle of 50° with the wall, is 44.7 inches.

a cube has a volume of 1 cubic unit. what is the perimeter of one of its face
Answer: One face of a cube has a perimeter of a+a+a+a=4a.
The required perimeter of one of the faces of the cube is 4 units.
Given that,
A cube has a volume of 1 cubic unit. what is the perimeter of one of its faces is to be determined.
Perimeter is the measure of the figure on its circumference.
A cube is defined is a regular 3-dimensional structure whose dimension at every section is identical.
Here,
According to the question,
Area of the square = 1 cubic unit
a² = 1
a = 1
Now,
The perimeter of the square = 4a
= 4 (1) = 4 units

The area equation for the given rhombus is:
A = (x^2 + 2x - 8) m^2
So the correct option is the second one.
How to get the area of the rhombus?
For a rhombus of diagonals d₁ and d₂, the area is given by:
A = (d₁*d₂)/2
In this case, we have:
d₁ = (2x + 8)m
d₂ = (x - 2)m
Then the area equation is:
A = (1/2)*(2x + 8)*(x - 2) m^2
A = (x + 4)*(x - 2) m^2
A = (x^2 - 2x + 4x - 8) m^2
A = (x^2 + 2x - 8) m^2
So the correct option is the second one.

Work out size of angle x
Answer:
x=120°
Step-by-step explanation:
120×2=240
360-240=120
x=120
Answer:
Angle x = 120 Degrees
Step-by-step explanation:
Formula for finding out total interior angles in a polygon = (Number of sides - 2) x 180 Degrees
e.g. Triangle have 3 sides
3 - 2 = 1
1 X 180 = 180
A Triangle has a total of 180 Degrees
Total Interior angle of a hexagon = 720 Degrees
Interior angle of a regular hexagon is 720 / 6 = 120
360 Degrees in a circle
360 - 120 - 120 = 120
If 20% of a number is 8, find 10% of that number.
Answer:
20%=8
10%=?

10×8=80
80÷20=4
Hence the answer is 4.
Answer:
4
Step-by-step explanation:
think about it we have 8 and 20 %, multiply 8 by 5 since theres 20 % and its 20 % of 100. 100 / 20 = 5 * 8 = 40 but since we have 20 and 10 % getting compared we obv know that it would be half what the answer for 20 % of would be so 4 :D

Find the image of Y(-7,4) after a dilation centered at the origin with a scale factor of -3
F= Y(-21,12)
G=Y(12,-21)
H=Y(21,-12)
J=Y(-12,21)
Answer:
H = Y (21, -12)
Step-by-step explanation:
Given
Y = (-7, 4)Dilation of -3Solving
Multiply the x-value and y-value of the coordinate by -3Y = (-7 x -3, 4 x -3)Y = (21, -12)The required image point is H=Y(21, -12)
What will happened with scale factor ?If the scale factor is given then by multiplying the scale factor with the co-ordinates gives us the image of the given point.
How to find the required image point ?Here the given point is Y(-7, 4)
After the dilation centered at origin, the scale factor is -3
∴ The x co-ordinate is (-7)×(-3)=21
