The values of x in the interval [0,2π] are given by:

[tex]\frac{5\pi}{6} \leq x\leq \frac{\pi}{6}[/tex]

Given: 9 sin (x) [tex]\leq \frac{9}{2}[/tex]

To find: Values of x in the interval [tex][0,2\pi][/tex].

Finding:

As 9 sin (x) [tex]\leq \frac{9}{2}[/tex],

=> [tex]sin(x)\leq \frac{1}{2}[/tex]

As, [tex]sin (\frac{\pi}{6})=sin(\frac{1}{2})[/tex],

=> [tex]sin(x)\leq sin(\frac{\pi}{6})[/tex]

=> [tex]x\leq \frac{\pi}{6}[/tex], i.e., the principle value of x.

As sin (x) = sin (π - x), [tex]\pi -x\leq \frac{\pi}{6}[/tex]

=> [tex]\pi -\frac{\pi}{6}\leq x[/tex]

=> [tex]\frac{5\pi}{6}\leq x[/tex]

Hence, the values of x in the interval [0,2π] are given by:

[tex]\frac{5\pi}{6} \leq x\leq \frac{\pi}{6}[/tex]

Answer:

11

Explanation:

Because 57 minus 2 games already equals 55, so 55 games divided by 5 months equals 11, so 11 games each month will get u to 57.

The number of games must his team win per month will be;

⇒ x > 11

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

Steve Conway wants his team to win more than 57 games this year.

And, His team has already won 2 games this season and there are 5 more months to play.

Now,

Let number of games must his team win per month = x

So, We can formulate the inequality as;

⇒ 5x + 2 > 57

Solve for x as;

⇒ 5x > 57 - 2

⇒ 5x > 55

⇒ x > 11

Thus, The number of games must his team win per month will be;

⇒ x > 11

Step-by-step explanation:

Slope is 1.5

Y intercept is (0,1) A

Equation y = (3x/2) + 1 = 1.5x + 1A

What does it mean by another solution?

If it means the other way to do slope (y=mx+b)

b=4−(3/2) * 2 = 1

We will solve this step-by-step. Also remember that (a -b) = -(b -a), when

a < b and -a-b = -(a + b)

So first solving by subtraction,[tex](-y^2-3y-5)-(3y^2-7y+4)=-y^2-3y-5-3y^2+7y-4= -4y^2 +4y-9[/tex]

Next, [tex]-4y^2+4y-9 -(2y^2+4y-9)=-4y^2+4y-9-2y^2-4y+9=-6y^2[/tex]

i.e., [tex]-6y^2-(2y^2-10y+4) = -8y^2+10y-4[/tex]

Answer:

x = 30

Step-by-step explanation:

5/6x- 1/5x =19

Get a common denominator of 30

5/6x * 5/5  - 1/5x * 6/6 = 19

25/30x - 6/30x = 19

19/30x = 19

Multiply each side by 30/19

19/30x * 30/19  = 30/19 * 19

x = 30

Answer:

5/6x- 1/5x =19

5/6x- 1/5x =19

?/30x=19

19/30x = 19

x = 19 / 19/30

x = 19 * 30/19

    √163 = x

Raise both sides to the second power

    (√163)2 = (x)2

    After squaring

    163 = x2  Rearranged equation

    x2  -163 = 0

    This equation has two real roots:

      x1 = ( 0 + sqrt(652) ) / 2 = 12.7671

     x2 = ( 0 - sqrt(652) ) / 2 = -12.7671  Original equation

Step-by-step explanation:

When the shadow is 45 meters long, it should be noted that the height of the utility pole will be 24 meters.

It should be noted that from the information, Antonio knows that a antenna that is 16 meters tall casts a shadow that is 30 meters long and he wants to calculate the height of a nearby pole.

Let the height be x.

Therefore, this will be illustrated as:

16 / 30 = x / 45

Cross multiply.

30 × x = 45 × 16

x = (45 × 16) / 30

= 24

Therefore, when the shadow is 45 meters long, it should be noted that the height of the utility pole will be 24 meters.

Answer:

Hope This Helps!

Answer:

70%

Step-by-step explanation:

Answer:

The correct option is A

Step-by-step explanation:

Since (1, 3) are the solutions to the function g(x), then

g(x) = (x – 1)(x – 3) = x² –3x – x + 3 = x² – 4x + 3

We know that f(x) is on the same plane and f(1) = 1.

Let's take g(1) = (1 – 1)(1 – 3) = 0

Therefore, when x = 1; f = 1 and g = 0. Hence

g(1) = f(1) – 1

In order words, g(x) could be f(x) – 1.

The correct option is A

Step-by-step explanation:

[tex] - 84 = 4(4r + 7) \\ - 84 = 16r + 28 \\ 16r = - 84 - 28 \\ 16r = - 112 \\ \frac{16r}{16} = - \frac{112}{16} \\ \\ \huge r = 7[/tex]
