Answer:
<h2>240.37 cm^2</h2>
Step-by-step explanation:
The question is on the mensuration of solids, a cylinder
Given data
height of cylinder h= 4 cm
diameter d= 9 cm
radius = d/2= 9/2= 4.5 cm
we know that the surface area of cylinder is
Substituting our data into the expression we have
<em> Therefore the total surface area is 240.37 cm^2</em>
B .......................
Answer:
23
Step-by-step explanation:
All triangles = 180 degrees
65 + 4x + x = 180
65 + 5x = 180
- 65 - 65
----------------------
5x = 115
--- = ----
5 = 5
x = 23
4(23) = 92
F = x = 23
B> 65
92 + 23 + 65 = 180
x = 23
F> = B>
Answer:
F⁻¹(x) = x/9
Step-by-step explanation:
To find the inverse of a function, you want to switch x and y in the equation and solve for y.
F(x) = 9x
x = 9F(x)
x/9 = F⁻¹(x)
Therefore, the inverse is F⁻¹(x) = x/9.
Given that you have given no options to choose, I will help you with <em>general statements</em> regarding this function. We have the following equation that is shown in the figure below:
So analyzing it we can say these propositions that are true:
1. This is a straight line.
2. This function always increases on the interval
3. The <em>y-intercept </em>is -2/3
4. The <em>x-intercept</em> is 1/6.
