The statement which is true about the function is that the function is negative for all real values of x where x < –3 or x > –1.

A function assigns the value of each element of one set to the other specific element of another set.

The graph of the function is,

[tex]f(x) = -(x +3)(x - 1)[/tex]

It is positive, its value is above x-axis. For the function above, the solutions are,

[tex]x+3=0\\x=-3\\x-1=0\\x=1[/tex]

The value of x is lies between,

[tex]-3 < x < 1[/tex]

Thus, the statement which is true about the function is that the function is negative for all real values of x where x < –3 or x > –1.

Answer:

Step-by-step explanation:

Here, it is given that the radius of sphere is 46.1 ft and we have to find the volume of the sphere .

So, we know that,

⇒ Volume(Sphere) = 4/3πr³

Now, Substituting the given values in the formula :

⇒ Volume(Sphere) = 4/3 × 3.14 × (46.1)³

⇒ Volume(Sphere) = 4/3 × 3.14 × 97972.18

⇒ Volume(Sphere) = 4/3 × 307632.64

⇒ Volume(Sphere) = 307,632.64 × 4/3

⇒ Volume(Sphere) = 1230530.59/3

⇒ Volume(Sphere) = 410176.86

Therefore,

The volume of a sphere with a radius of 46.1 feet is 410176.9 cubic foot.

The volume of sphere is the measure of space that can be occupied by a sphere.  If the radius of the sphere formed is r and the volume of the sphere is V. Then, the volume of the sphere is given by: Volume of Sphere, V = (4/3)πr³

Given that, the radius of a sphere = 46.1 feet.

Here, volume = 4/3 ×3.14×46.1³

= 410176.864

≈ 410176.9 cubic foot

Therefore, the volume of a sphere with a radius of 46.1 feet is 410176.9 cubic foot.

Step-by-step explanation:

h ( x ) = - x - 4

To find : h ( - 6 )

h ( - 6 ) = h ( x )

Here,

x = - 6

h ( - 6 ) = - x - 4

           = - ( - 6 ) - 4

           = 6 + 4

h ( - 6 ) = 2

The value of log subscript 6 baseline start fraction 1 over 36 end fraction is -2.

Let  x is the unknown value

We have to determine the value of x

[tex]Log_6 ( 1/36) = x....Given[/tex]

Logarithmic functions are the inverses of exponential functions, and an exponential function can be expressed in logarithmic form.

[tex]( 1/36) = 36^{-1} = (6^{2})^{-1} = 6^{-1}[/tex]

[tex]Log_6( 1/36) = Log_6 6^{-2} = -2 Log_6 6[/tex]

We know that,

[tex]log_aa=1[/tex]

Therefore by applying the above rule of log we have

[tex]Log_6 6 = 1[/tex]

Therefore we get

[tex]-2 Log_6 6 = -2(1) = -2[/tex]

Therefore option 2 is correct.

0.25 is the probability that the randomly selected candy is orange

Answer:

Our answer has to be B because we need to develop an equation to solve for the value of each term in order to find the number pattern.

Step-by-step explanation:

This is a sequence problem.

You need to identify the relationships between the given number pattern.

If we look at -14 and -8, you can clearly see that something is happening.

If we were to do -14+6 that would equal to -8

Then we try the other one like -8 and -2. We can do -8 + 6 = -2

So our sequence/number pattern is that we're increasing by 6.

We could also develop an equation: -14 + x= -8

Our answer has to be B because we need to develop an equation to solve for the value of each term in order to find the number pattern.

Reason:

There's a 30% chance they buy the popcorn, which means there's a 70% chance they don't buy it.

100% - 30% = 70%

Then convert the 70% to 0.7

Answer:

0.7 or 70%

Step-by-step explanation:

0.3 * 100 = 30%

100%-30% = 70%

You either buy or not. If 30% you don't then 70% you do.

Step-by-step explanation:

3x -(7-x) = 29       remove the parens

3x - 7 + x = 29     simplify

4x -7 = 29            add 7 to both sides of the equation

4x = 36            divide by

x = 9

then 6x = 6 * 9 = 54

Answer:

54

Step-by-step explanation:

3x -(7-x) = 29

3x - 7 + x = 29

4x -7 = 29

4x = 36

x = 9

6x = 6 x 9

6 x 9 = 54

x = 5

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

21x + 5 is an exterior angle of the triangle , then

21x + 5 = 5 + 13x + 40

21x + 5 = 13x + 45 ( subtract 13x from both sides )

8x + 5 = 45 ( subtract 5 from both sides )

8x = 40 ( divide both sides by 8 )

x = 5

Answer:

x=5

Step-by-step explanation:

Angles Q and R are supplementary

13x  + 21x +5 = 180
