We firstly calculate the angle at the bottom left of the triangle(theta)..,
; Angle theta...
tan theta = 9/11
Angle theta = tan^-1(9/11)
; Angle theta = 39.3°
Then height x...we then use the smaller triangle..,
; tan (39.3°) = x/5.5
; x = 5.5 tan(39.3°)
Hence... x = 4.5
Answer:
373.66 cm².
Step-by-step explanation:
The following data were obtained from the question:
Pi (π) = 3.14
Radius (r) = 7 cm
Slant height (l) = 10 cm
Surface Area (SA) =?
The surface area of the cone can be obtained by using the following formula:
SA = πr² + πrl
SA = (3.14 × 7²) + (3.14 × 7 × 10)
SA = (3.14 × 49) + 219.8
SA = 153.86 + 219.8
SA = 373.66 cm²
Therefore, the surface area of the cone is 373.66 cm².
Given:
The of values of a function.
To find:
The ordered pairs that are found on the graph of the inverse function.
Solution:
If a function is defined as

Then its inverse function is defined as

From the given table it is clear that, the ordered pairs of the function f(x) are :

So, ordered pairs of the inverse function are :

Therefore, the correct option is B.
<span>Answer: Skewed to right with mean 0 and S.D. 1
Explanation: Let's assume the z-scores as a linear transformation.
then z=(x-mean)/S.D. = (x-30)/15
z(mean) = (30-30)/15= 0
z(sigma) = 15/15 = 1
Note: Shape does not change.</span>
