Answer:
Cost = 2x + 180
Step-by-step explanation:
Let the number of pages of a book be x
Cost of the first ten pages = $20 × 10
= $200
The number of remaining pages is; x - 10
Cost of the remaining pages = $2 × (x-10)
= $(2x-20)
Total cost of the book= 200 + 2x - 20
= 2x + 180
Answer: 62.8in
Step-by-step explanation:
The formula for circumference is C=2πr. Put the values of 10 in for r and 3.14 in for pi, and you get an equation that looks like C=2(3.14)(10). Solving this equation gets you 62.8.
It would be equal to (6x6) x (2x6) x (2x6) x (2x6) x (2x6). Look that up.
By graphing the given points, we will get the attached figure
which represents:
f(x) = 3 sin x
but sin x = cos (x - π/2)
∴ f(x) = 3 cos ( x - π/2 )
The correct choice is option ⇒⇒⇒ <span>f(x) = 3 cos(x − pi over 2 )

Answer:
6x^2 + 4x
Step-by-step explanation:
g(x) + f(x)
= -8x^2 - 3x + 5 + 2x^2 + 7x - 5
= -8x^2 + 2x^2 - 3x + 7x + 5 - 5
= - 6x^2 + 4x
