8 0

Answer:

8

Step-by-step explanation:

(f• g)(x) = f(x) × g(x)

= 2^{x} × (2x - 5)

To evaluate (f • g)(3) , substitute x = 3 into the expression

= 2³ × ( 2(3) - 5)

= 8 × (6 - 5)

= 8 × 1

= 8

The rectangular prism shown has a length of 10 cm, a width of 10 cm, and a height of 6 cm. Find the length of the inner diagonal
melamori03 [73]
<h3>Answer:</h3>

15.36 cm

<h3>Explanation:</h3>

The Pythagorean theorem tells you ...

... AC² = AB² + BC² . . . . . relation for face diagonal

... AD² = AC² + CD² . . . . . relation for space diagonal

Subsituting the expression for AC² given by the first equation, the second equaiton becomes ...

... AD² = AB² + BC² + CD²

... AD² = (100 cm²) + (100 cm²) + (36 cm²) = 236 cm²

Taking the square root, we have ...

... AD = √236 cm = 2√59 cm

... AD ≈ 15.36 cm

In the diagram, AB = 12, DX = 2.5, and BX = 5. Find CD. Show all work.
Naily [24]
I found your complete question in another source.
 See attached image. 
 For this case what you should see is that you have two similar triangles.
 We then have the following relationship:
 ((AB) / (BX)) = ((CD) / (DX))
 We cleared CD:
 CD = ((AB) / (BX)) * (DX)
 Substituting the values:
 CD = ((12) / (5)) * (2.5)
 CD = 6
 Answer: 
 CD = 6

What is the standard form of the following equation y + 3 = 1/4x Use integers for A,B, and C.
Nezavi [6.7K]

Answer:1/4x+y=-3

Step-by-step explanation:

You have to move 1/4x to the left side by adding the inverse of 1/4x, -1/4x to each side. Then you have 1/4x+y+3=3. After this you have to use the subtraction property of equality. Then your answer is 1/4x+y=-3
