The graph below shows three functions: Graph of function f of x equals 0.5 to the power x. Graph of function g of x is a line se

gment with holes at endpoints connecting negative 1.8, negative 3 and 1, 3.8. Graph of p of x is a line segment connecting negative 1.7, 2.3 and 1, negative 4.2. Which function has all real numbers as its domain?

Answer:   f(x)= 0.5^x has all real value as its domain.

Explanation: since, we have three functions f(x)=0.5^x,

while g(x) and p(x) are line segments.

Now, g(x) is a function by a line segment which passes through two points (-1.8,-3) and ( 1,3.8).

Thus it is clear that its domain will be the ends points. so domain of the function g(x) will be [-1.8, 3.8] which is the subset of real numbers set (R).

Similarly, domain of function p(x) will be [1.7, 1], which is also the subset of R.

But, when we talk about f(x) it contains all the possible value of x. Thus we can say that f(x)= 0.5^x has R as its domain.

<span>p(x) contains all real numbers as its domain because both of the other functions are only line segments and cover a finite interval of x.</span>

It usually works well to do what the instructions tell you. Multiply each diameter by 3.14.

a) 3.14×6 cm = 18.84 cm

b) [can't read the picture]

d) 3.14×9 in = 28.26 in

e) 3.14×11 mm = 34.54 mm

Brittany and Ashley can paint a room in 7 hours if they work together. If Ashley were to work by himself, it would take him 2 ho
stich3 [128]

Answer:

Step-by-step explanation:

Brittany paints the room in x hours, completing 1/x of the room per hour.

Ashley paints the room in x+2 hours, completing 1/(x+2) of the room per hour.

Working together, they complete 1/x + 1/(x+2) = ⅐ of the room per hour.

7(x+2) + 7x = x(x+2)

14x + 15 = x^2 + 2x

x^2 - 12x - 15 = 0

x = [12 ±√(12²+60)]/2= 6±√51

6-√51 is an extraneous solution.

x = 6+√51 ≈ 13.14

Brittany paints the room in 12.14 hours
