Find the axis of the graph of the function..f(x) = 4x2 + 8x + 7

1 answer:

7 0

F ( x ) = 4 x² + 8 x + 7
a = 4, b = 8
The axis formula is:
x = - b / 2 a
x = - 8 / (2*4) = - 8 / 8 = -1
Answer:
The axis of the graph of the function is x = - 1.

How do you factor 125-x^3?

xz_007 [3.2K]

Step-by-step explanation:

We have

$125 - x {}^{3}$

First, 125 is a perfect cube because

$5 \times 5 \times 5 = 125$

and

x^3 is a perfect cube because

$x \times x \times x = x {}^{3}$

so we can use the difference of cubes identity

$( {x}^{3} - {y}^{3} ) = (x - y)( {x}^{2} + xy + {y}^{2} )$

Let say we have two perfect cubes:

64 because 8×8×8=64

and 27 because 3×3×3=27 and let subtract

$64 - 27$

we know that

$64 - 27 = 37$

but using the difference of cubes identity we should get the same thing.

Remeber cube root of 64 is 4 and cube root of 27 is 3 so we have

$(4 - 3)( {4}^{2} + 4(3) + 3 {}^{2} )$

$1(16 + 12 + 9) = 1(37) = 37$

So the difference of cubes works for real numbers. This is a good way to help remeber the identity using real numbers.

Back on to the topic,

we know that 5 is cube root of 125 and x is the cube root of x^3 so we have

$(5 - x)( {5}^{2} + 5x + {x}^{2} ) =$

$(5 - x)(25 + 5x + {x}^{2} )$

50 1/2 divided by 1/4 = 202<br> How are the numbers related?

Stels [109]

Answer:

see the explanation

Step-by-step explanation:

Let

$x=50\frac{1}{2}=\frac{50*2+1}{2}=\frac{101}{2}$

$y=\frac{1}{4}$

Find the ratio x/y

$\frac{x}{y}=\frac{(101/2)}{(1/4)} =\frac{101*4}{2*1}=202$

therefore

$\frac{x}{y}=202$

$x=202y$

That means----> The first number (50 1/2) is 202 times greater than the second number (1/4)
