Answer:
(e) 1 =64⁰
(f) 1/64 = 64⁻¹ negative one power
(g) 1/8 = 64⁻¹/² negative one half power
(h) 1/2 = 64⁻1/6 negative one/sixth power
(I) 1/64 same as (f) ??
Step-by-step explanation:
Let x represent the price they charge hardcover book and let y represent the price they charge for a paperback book.
4x + 10y = 62 . . . . . (1)
5x + 7y = 61 . . . . . . (2)
(1) x 5 ⇒ 20x + 50y = 310 . . . . (3)
(2) x 4 ⇒ 20x + 28y = 244 . . . . (4)
(3) - (4) ⇒ 22y = 66
y = 66 / 22 = 3
4x + 10(3) = 62
4x = 62 - 30 = 32
x = 32 / 4 = 8
Therefore, the price for a hardcover book is $8 and the price for a paperback book is $3.

Answer:
C
Step-by-step explanation:
When we set the numerator equal to 0 and solve for x, that value is the horizontal asymptote (a line the graph come towards, but never crosses).
Looking at the graph, the horizontal asymptote is x = 2, so which one of the 4 functions has a horizontal asymptote of 2? Let's check.
A) 2x - 1 = 0
x = 1/2
B) same, x = 1/2
C) 2x -4 = 0
x = 2
D) same as A,B, x = 1/2
As we can see, option C has the right horizontal asymptote and A,B,D are eliminated. So answer is C.
Answer:
640.919 feet
Step-by-step explanation:
Given that there is an antenna on the top of a building. From a location 400 feet from the base of the building, the angle of elevation to the top of the building is measured to be 37°. From the same location, the angle of elevation to the top of the antenna is measured to be 40°
Let the height of building be x and that of antenna be y.
Then by considering right angle formed by horizontal line, vertical height and line made by eye contact we have
Next considering the height with antenna included we get total height
