Answer:
see explanation
Step-by-step explanation:
a
The tangent and the radius at the point of contact form a right angle
Using Pythagoras' identity on the right triangle formed.
Let x be the distance from the centre to P, then
x² = 4² + 10² = 16 + 100 = 116 ( take the square root of both sides )
x =  ≈ 10.77 cm (to 2 dec. places )
 ≈ 10.77 cm (to 2 dec. places )
b
let the required angle be Θ, then
Using the sine or cosine ratio in the right triangle.
cosΘ =  =
 = 
Θ =  (
 (  ) ≈ 21.8°
 ) ≈ 21.8°
 
        
             
        
        
        
<span>What is the y-intercept of the plane whose equation is 4x + 5y + z = 20?
(0, 4, 0) 
Which equation has intercepts at X(1, 0, 0), Y(0, 1, 0), and Z(0, 0, 2)?
2x + 2y + z = 2
Which equation is equivalent to x + 3y + z = 3?
4x + 12y + 4z = 12
Which of the following points lies in the plane 3x + 2y + 4z = 12?
(4, 3,2)

Answer:
5/11
Step-by-step explanation:
let x=0.4545...
100x=45.4545...
100x-x = 99x=45.4545... - 0.4545...=45
x=45/99=5/11
 
        
             
        
        
        
Answer:
-64
Step-by-step explanation:
The question is asking to solve 
Notice how the -4 is in parenthesis. This means that along with the 4 being multiplied, the negative is too.
 is the same as -4 · -4 · -4
 is the same as -4 · -4 · -4
First let's figure out if this will be negative or positive
Whenever the exponent is odd and there is a negative in the parenthesis the answer will be negative and if its even it will be positive
Now find out what 4 x 4 x 4 equals (64)
In conclusion the answer is -64
