Answer:
sec(A) = -(1/5)√74
Step-by-step explanation:
Solving the equation for y, we have ...
-7x = 5y
-7/5x = y
The slope of this line (-7/5) is the tangent of the angle (A) it makes with the x-axis. The secant satisfies the relation ...
sec(A)^2 = 1 + tan(A)^2
sec(A) = √(1 +tan(A)^2)
sec(A) = -√(1 +(-7/5)^2) = -√(74/25) . . . . secant is negative in 2nd quadrant
sec(A) = -(1/5)√74
Answer:
see explanation
Step-by-step explanation:
Since the dilatation is centred at the origin with a scale factor of .
Then the coordinates of the image are one half the coordinates of the original, that is
A(3, 4 ) → A'(1.5, 2 )
B(- 7, 2 ) → B'(- 3.5, 1 )
C(2, 2 ) → C'(1, 1 )
The correct answer: " f(x) = -5 " . { when x = -1 } .

The <u>correct answer</u> is:
125,000.
Explanation:
For the first turn, there are 50 numbers to choose from.
On each turn of a lock, the numbers can be repeated; this means on the second turn, there are 50 numbers to choose from, and on the third turn, there are 50 numbers to choose from. This gives us:
50³ = 50×50×50 = 125,000.
Answer:
1/27
Step-by-step explanation:
(1/27)^2016*27^2015 =
27^-2016 * 27^2015 =
27^(-2016+2015) =
27^-1 =
1/27
