Answer:

6. 4.8m

7. a. 48 b. 31.4 c. 170

Step-by-step explanation:

6. 4.5^2 x 1.6^2 = c^2

   22.81 = c^2

   square root of 22.81 = 4.8

7.

a. 12^2 x 16^2 = c^2

   400 = c^2

   square root of 400 is 20, 20 + 12 + 16 = 48

b. 9^2 x b^2 = 13^2

   88 = b^2

   square root of 88 is 9.4, 9.4 + 9 + 13 = 31.4

c. 25^2 x b^2 = 65^2

   3600 = c^2

   square root of 3600 is 60, 60 + 60 + 25 + 25 = 170

F(1)=_________________________
olga nikolaevna [1]

Answer:

f(1) = 1

Step-by-step explanation:

The value of f(1) simply means what is the corresponding output we would get for an input of 1.

This also implies that for what of y is x equal to 1?

From the graph, when x = 1, y = 1.

Thus:

f(1) = 1

If m < 0 and b > 0, the graph of y = mx + b does not pass through which quadrant?
stiks02 [169]

Answer:

Quadrant III


Step-by-step explanation:

The attached picture shows graph of 4 such linear functions with the conditions given in the problem. ALL of them DO NOT pass through Quadrant III.

The graphs shown are of the functions:

y=-2x+1

y=-3x+3

y=-x+0.5

y=-5x+2


<em>So, any linear function of the form  y=mx+b  with  m  and  b>0  does not pass through Quadrant III. Answer choice 3 is correct.</em>

The function h ( x ) = 1 x − 1 h ( x ) = 1 x - 1 can be expressed in the form f ( g ( x ) ) f ( g ( x ) ) , where g ( x ) = ( x
Radda [10]

Answer: f(x) = 1^(x + 1)

Step-by-step explanation:

we have that h(x) = 1^x

and h(x) = f(g(x))

This mean that we are evaluating the function f(y) in the point y = g(x)

where g(x) = x - 1

then:

f(g(x) = f(x - 1) = h(x) = 1^x

then we should have that:

f(x) = 1^(x + 1)

then:

f(x - 1) = 1^(x - 1 + 1) = 1^x
