Answer:

47

Step-by-step explanation:

You would just do the opposite. Instead of multiplying the .43 by the original you divide the product by .43 to get 46.5. 46.5 rounded is 47.

Use the inequalities to describe the shaded area on the grid​
raketka [301]
The shaded area would be 2 because there is a whole square shaded in the the other two are 1/2 so if you add 1/2 together with another 1/2 plus the whole shaded square you would get two.


At least that’s what I understood from the question

PLS HELP ILL MARK CROWN
jok3333 [9.3K]

Answer:

4x−7

Step-by-step explanation:

Being given our polynomial:

4x^{2}+ x - 14,

We must find the roots to get our answer.

x = (- 1 ± √(1 - 4*4*(-14)) / 8

x = (- 1 ± √225) / 8

x = ( -1 ± 15) / 8

x₁ = (- 1 + 15)/ 8 = 14/8 = 7 / 4

x₂ = (- 1 - 15) / 8 = - 16/2 = - 8

The factors we came up with:

(x - x₁)(x - x₂)

(x - 7/4)(x + 8)

1/4(4x - 7)(x + 8)

So,

The correct option is C.

Somebody, please help
SashulF [63]
F(x) can be written as:
f(x) = Asin(2x); where A is the amplitude and the period of the function is half that of a normal sin function.
f(π/4) = 4
4 = Asin(2(π/4))
4 = Asin(π/2)
A = 4
Amplitude of g(x) = 1/2 * amplitude of f(x)
A for g(x) = 2
g(x) = 2sin(x)
