Answer:

-  \frac{ 1}{2}

Step-by-step explanation:

d \times 24 =  - 12 \\ 24d =  - 12 \\  \frac{24d}{24}  =  \frac{ - 12}{24}  \\ d =  -  \frac{  1}{2}

Answer: d=-1/2

<u>Move all terms to the left</u>

<u></u>d*24-(-12)=0<u></u>

<u></u>

<u>Add all the numbers together, and all the variables</u>

<u></u>d*24+12=0<u></u>

<u></u>

<u>Multiply elements</u>

<u></u>24d+12=0<u></u>

<u></u>

<u>Move all terms containing d to the left, all other terms to the right</u>

<u></u>24d=-12\\-12/24\\d=-1/2<u></u>

7/11 converted to a decimal rounded up 2 places
astraxan [27]

Answer:

0.636

Step-by-step explanation:

First off, we'll interpret the fraction bar to mean "divided by." This means that 7/11 is the same as 7 divided by 11.

Second, you have requested to see 2 decimal places in your answer, so we'll write the 7 as 7.00 instead (a 7 with 2 zeros after the decimal point).

Now, we'll just do what the fraction bar says: divide 7.00 by 11:

And that's about it! 7/11 written as a decimal to 3 decimal places is 0.636.

What is the value of sin-1(1)? negative startfraction pi over 2 endfraction 0 startfraction pi over 2 endfraction π
mariarad [96]

The value of sin-1(1) is negative startfraction pi over 2 endfraction, startfraction -pi over 2 endfraction.

<h3>What is the value of sin (π/2)?</h3>

The value of sin (π/2) is equal to the number 1. The value of the sin-1(1) has to be find out.

Suppose the value of this function is <em>x</em>. Thus,

x=\sin^{-1}(1)

Solve it further,

\sin(x)=(1)              ......1

The value of sin (π/2) and -sin (-π/2) is equal to 1 such that,

\sin\dfrac{\pi}{2}=-\sin\left(-\dfrac{\pi}{2}\right)=1

Put this value in the equation 1,

\sin(x)=\sin\left(\dfrac{\pi}{2}\right)=-\sin\left(-\dfrac{\pi}{2}\right)

Thus, the range will be,

\left(\dfrac{\pi}{2},-\dfrac{\pi}{2}\right)

Thus, the value of sin-1(1) is negative startfraction pi over 2 endfraction, startfraction -pi over 2 endfraction.

See the attachment below for the question.
tangare [24]

Answer:

The correct answer is third option

x = 3

Step-by-step explanation:

It is given that,

4ˣ = 8⁽ˣ ⁻ ¹⁾

<u>To find the value of x</u>

4ˣ  = (2²)ˣ

8⁽ˣ ⁻ ¹⁾ = (2³)⁽ˣ ⁻ ¹⁾

4ˣ = 8⁽ˣ ⁻ ¹⁾

(2²)ˣ =  (2³)⁽ˣ ⁻ ¹⁾

2²ˣ = 2⁽³ˣ ⁻ ³⁾

2x = 3x - 3

3x - 2x = 3

x = 3

The correct answer is third option

x = 3

Wires are attached to a pole to make it more secure. The diagram shows one of those wires having a length of 220 feet. The angle
LuckyWell [14K]
The wire, the pole and the segment joining the leg of the pole to the wire in the ground form a right triangle whose hypotenuse is the wire, and the side opposite to the angle 36° is the pole.

By right triangle trigonometry, sin36°=(opposite side)/(hypotenuse.)

Substituting, we have 0.588=(opposite side)/220, thus the length of the opposite side, which represents the length of the pole, is 

                                       0.588*220 ft=129.3 ft
