Answer:
C. 7 units down
Step-by-step explanation:
The y-coordinate of a point on a graph is the function value. It tells how far up from the x-axis the point is located. When 7 is subtracted from the function value, the y-coordinate is 7 less than it was. That is, the point has moved 7 units down.
9.6 is your answer! (nine and six tenths)
X^2/a^2+y^2/b^2=1
a^2=100 a=10
b^2=64 b=8
c^2=a^2-b^2
c=6

x² - 49
--------------------------------------------------
Form into 2 perfect squares
---------------------------------------------------
x² - 7²
--------------------------------------------------
Formula
---------------------------------------------------
a² - b² = (a + b) (a - b)
--------------------------------------------------
Apply the formula
---------------------------------------------------
x² - 7² = (x + 7)(x - 7)
--------------------------------------------------
Answer: (x + 7)(x - 7)

Answer:
(10 + 3√3) / 6.
Step-by-step explanation:
cosA = 1/secA = 1 / 2/√3 = √3 /2.
If we consider a 30-60-90 triangle if cosA = √3/2, sinA = 1/2 and
tanA = 1/√3.
So the answer is:
1/√3 / √3 /2. + 1 + 1/2 / 1/√3
= 2/3 + 1 + √3/2
= 5/3 + √3 /2
= (10 + 3√3) / 6.
