Use the Intermediate Value Theorem to show that there is a root of the given equation in the specified interval.

Olin [163]

Answer:

The correct option is d

$f(1) = -5$

$f(2) = 11$

The correct option is d

The correct option is c

the correct option is b

Step-by-step explanation:

The given equation is

$f(x) = x^4 + x -7 =0$

The give interval is $(1,2)$

Now differentiating the equation

$f'(x) = 4x^3 +7 > 0$

Therefore the equation is positive at the given interval

Now at x= 1

$f(1) = (1)^4 + 1 -7 =-5$

Now at x= 2

$f(2) = (2)^4 + 2 -7 =11$

Now at the interval (1,2)

$f(1) < 0 < f(2)$

i.e

$-5 < 0 < 11$

this tell us that there is a value z within 1,2 and

f(z) = 0

Which implies that there is a root within (1,2) according to the intermediate value theorem

A rectangular athletic field is three times as long as it is wide. If the perimeter of the athletic field is 128 yards, what are

larisa [96]

Length=3x
Width=x
3x+x+3x+x=128
8x=128
Divide both sides by 8
x=16
3(x)
3(16)=58
Width= 16 yards
Length= 58 yards

Answer:

= -----------

6(x + 7)

Step-by-step explanation:

3x - 21 x^2 - 49

----------- ÷ -------------

18x - 18 x - 1

3x - 21 x - 1

----------- × -------------

18x - 18 x^2 - 49

Factor the top left:

3x - 21 = 3(x - 7)

Factor the bottom left:

18x - 18 = 18(x - 1)

Factor the new bottom right:

x^2 - 49 = (x + 7)(x - 7)

Multiply and simplify the faction:

3(x - 7) x - 1

----------- × -----------------

18(x - 1) (x + 7)(x - 7)

= -------------

6(x + 7)
