Answer:

x = 11

Step-by-step explanation:

Complementary means they add up to 90°

So add the angles up and set them equal to 90°

3x - 4 + 5x + 6 = 90

ADD the x's

8x - 4 + 6 = 90

COMBINE the -4 and 6

8x +2 = 90

SUBTRACT 2 from both sides.

8x = 88

DIVIDE by 8 on both sides.

8x/8 = 88/8

x = 11

Answer:

x = 11

Step-by-step explanation:

Complementary angles are the angles which are added up to 90°.

As, the given angles are complementary,

(3x - 4) + ( 5x + 6 ) = 90

Now solve for x.

(3x - 4) + ( 5x + 6 ) = 90

3x - 4 + 5x + 6 = 90

8x -4 + 6 = 90

8x + 2 = 90

8x = 90 - 2

8x = 88

Divide both sides by 8.

x = 11

Find an upper limit for the zeroes 2x^4 -7x^3 + 4x^2 + 7x - 6 = 0

erik [133]

<u>Answer-</u>

2 is the upper limit for the zeros.

<u>Solution-</u>

The given function f(x) is,

$2x^4 -7x^3 + 4x^2 + 7x - 6 = 0$

For calculating the zeros,

$\Rightarrow f(x)=0$

$\Rightarrow 2x^4 -7x^3 + 4x^2 + 7x - 6 = 0$

$\Rightarrow 2x^4-4x^3-3x^3+6x^2-2x^2+ 4x+3x-6=0$

$\Rightarrow 2x^3(x-2)-3x^2(x-2)-2x(x-2)+3(x-2)=0$

$\Rightarrow (x-2)(2x^3-3x^2-2x+3)=0$

$\Rightarrow (x-2)(x^2(2x-3)-1(2x-3))=0$

$\Rightarrow (x-2)(x^2-1)(2x-3)=0$

$\Rightarrow (x-2)(x+1)(x-1)(2x-3)=0$

$\Rightarrow x-2=0,\ x+1=0,\ x-1=0,\ 2x-3=0$

$\Rightarrow x=2,\ x=-1,\ x=1,\ x=\frac{3}{2}$

From all the 4 roots, it can be obtained that 2 is the greatest zero.

Make a number that has a 6 that is 10 times the value of the digit 6 in 165,438 Comparing digits in whole numbers

Ipatiy [6.2K]

Answer:

An example of such number is 1,645,378 ( The value of 6 here is 600,000)

Step-by-step explanation:

Here, we want to compare digits in whole

numbers.

The value of 6 in 165,438 = 60,000

Now, we want a number that is 10 times the value of 6 here

10 times the value of 6 here will be 10 * 60,000 = 600,000

So we want a number which has the value of 6 in it as 600,000

The number in this case as an example can be ;

1,645,378

A sound wave has a frequency of 627 hz and a wavelength of 3.25 m. what is the speed of the wave?

Dovator [93]

Answer:

2037.75m/s

Step-by-step explanation:

To calculate the speed of a wave, you need to multiply the wavelength by the frequency. In this case, 627*3.25=2037.75m/s. Hope this helps!
