Answer:

It's B for the first one.

For the second one, it is C

Step-by-step explanation:

30 * 0.3 = 9

So 30% of 30 is 9. She did 9 windows.

0.52 = 52/100

It's 52/100 because 0.52 = 52%. 52% then equals 52/100.

52/100 = 13/25

So the answer is 13/25

Find the value of x if y=2.5 on the graph of 2x-1=y
Romashka-Z-Leto [24]

Answer:

2x - 1 = y

2x - 1 = 2.5

Use inverse operations

2.5 + 1 = 3.5

3.5 / 2 = 1.75

2 x 1.75 - 1 = 2.5

x = 1.75

The degree of the polynomial function f(x) is 3. The roots of the equation f(x)=0 are −4 , 0, and 2. Which graph could be the gr
KATRIN_1 [288]

We know that the polynomial function is of degree 3, and that its roots are -4, 0, 2.

With this data we can write a generic equation for the function:

f (x) = bx (x + 4) (x-2)

Since the function is of degree 3 and cuts the axis at x = 0, then it has rotational symmetry with respect to the origin.

The graph of the function can be of two main forms, based on the value of the coefficient b.

If b is positive then the function grows from y = -infinite and cuts the x-axis for the first time in -4. Then it decreases, cuts at x = 0 and begins to grow again cutting the x-axis for the third time at x = 2. and continues to grow until y = infnit


If b is negative, then the function decreases from y = infinity and cuts the x-axis for the first time in -4. Then it grows, cuts at x = 0 and begins to decrease again by cutting the x-axis for the third time at x = 2, and continues to decrease until y = -infnit.


In the attached images the graphs of the function f (x) are shown assuming b = -1 and b = 1

Select one or more expressions that together represent all solutions to the equation your answer should be in radians sin(x) = -
Sonja [21]

Answer:

-0.25268 rad + 2πn  ,   3.394273 rad + 2πn

 ≈  - π /12 + 2πn,   π + 2πn

Step-by-step explanation:

sin( x ) = -0.25

x = sin^-1 ( -25 )

 The solutions of the equation  sin( x ) = -0.25 are :

X = -0.25268rad + 2πn  ,    3.394273rad + 2πn

  ≈  - π /12 + 2πn,   π + 2πn
