Answer:

(fog)(2)=2

Step-by-step explanation:

Given

f(x)= -2x+8

and

g(x)= √(x+7)

For finding (fog)(2), we have to find (fog)(x) first

In order to find (fog)(x) we will put the value of g(x) in f(x) in place of x.

(fog)(x)= -2g(x)+8

Putting the value of g(x)  

(fog)(x)= -2√(x+7)+8

We have to find (fog)(2), so we have to put at the place of x in the composition

(fog)(x)= -2√(2+7)+8

(fog)(x)= -2√9+8

= -2(3)+8

= -6+8

=2

So,

(fog)(2)=2   ..

Answer:

C

Step-by-step explanation:

The equation represents speed as a function of time. The point (3,120) implies that the car with a speed of 40 miles per hour, travelled a total of 120 miles in a time span of 3 hours.

In this scenario, the equation ys = 40x relates the speed of the car (40 miles per hour) to the time travelled (x in hours). The 'y' in the equation represents the distance travelled by the car. So, when interpreting the point (3,120) on the graph for this equation, '3' refers to time (hours) and '120' refers to distance travelled (miles).

Thus, the point (3,120) on the graph signifies that the car travelled 120 miles in 3 hours, so the correct answer is C. The car traveled 120 miles In 3 hours.

Answer: 1/2, because its 0.583 and 1/2 is 0.5

Step-by-step explanation:

Answer:

Final answer is 1/2.

Step-by-step explanation:

Given numbers are 0, 1/2 and 1.

Now we need to find about which one of those three numbers is close to 7/12.

Since 7/12 has denominator 12 so let's convert each of the given number into their equivalent fractions with denominator 12.

0=0/12

1/2=6/12

1=12/12

Now we can easily compare them with 7/12 and find that 6/12 or 1/2 is closest.

Hence final answer is 1/2.

Answer:

Subtract 360° to find a negative coterminal angle. Angles that measure 240° and –480° are coterminal with a –120° angle. For an angle θ in standard position, the reference angle is the positive acute angle formed by the terminal side of θ and the x-axis.

Step-by-step explanation:

Combing like terms you have 0.25k - k = -0.75k

and 1.5 - 3.5 = -2.0

The answer would be -0.75k - 2.0

0.25k + 1.5 - k - 3.5

You must combine like terms. Like terms are the numbers with the same variable (letter) attached (in this case the numbers with the letter k are like terms)

(0.25k + (-k) )+ 1.5 - 3.5 <<<Remember that a variable with no number in front of it still has and invisible 1

(0.25k + (-1k) ) + 1.5 - 3.5

-0.75k + 1.5 - 3.5  

Numbers without any variable are also like terms

-0.75k + 1.5 - 3.5

-0.75k -2

Answer:

Bianca can make 28 pans of brownies in 7 hours

Step-by-step explanation:

As we know, 1 hour = 60 minutes

so, 1/2 hour = 30 minutes

Bianca takes 1/2 hour to make pans of brownies = 2 pans

Bianca takes 1 hour to make pans of  brownies = 2 / (1/2) pans

Bianca takes 7 hour to make pans of  brownies = 4 * 7 pans

                                                                                = 28 pans

So, Bianca can make 28 pans of brownies in 7 hours.

The third option,

c) [tex]h(x)=2.25x-22[/tex]

We are given the functions E(x) and K(x), since they both are function of the same variable, we need to calculate the difference between them.

From the statement we know the functions:

[tex]f(x)=9.75x+62[/tex]

and

[tex]g(x)=7.5x+84[/tex]

So, calculating the difference the functions we have:

[tex]h(x)=f(x)-g(x)[/tex]

[tex]h(x)=(9.75x+62)-(7.5x+84)[/tex]

[tex]h(x)=(9.75x+62)-(7.5x+84)[/tex]

[tex]h(x)=9.75x-7.5x+62-84[/tex]

[tex]h(x)=2.25x-22[/tex]

Hence, the answer is the third option,

c) [tex]h(x)=2.25x-22[/tex]

Have a nice day!

Answer: Option C

[tex]h(x)=2.25x-22[/tex]

Step-by-step explanation:

To find the function h(x) that models the difference between Hector's and Cari's gains, subtract the functions f(x) with g(x)

That is to say:

[tex]h (x) = f (x) -g (x)[/tex]

We know that

[tex]f (x) = 9.75x + 62\\\\g (x) = 7.5x + 84[/tex]

Then we can find the function h(x)

[tex]h(x) = 9.75x + 62 - (7.5x + 84)\\\\h(x) = 9.75x + 62 -7.5x -84[/tex]

The table that best shows the impacts resulting from human activity is:

Impact of Human Activities

Human Activity Impact

Forest area cleared to construct an airport Increase in sound pollution

Vegetation cleared to construct a power plant Contamination of water

Hence the correct option is 2.

In the table illustrating the impacts resulting from human activities, the most fitting combination is the one stating that clearing forest areas to construct an airport leads to an increase in pollution, while the vegetation cleared for a power plant results in the contamination of water.

This pairing accurately reflects the environmental consequences associated with these specific human actions. When forests are cleared for airport construction, it often involves disrupting ecosystems, releasing pollutants, and contributing to air pollution.

On the other hand, clearing vegetation for a power plant can lead to water contamination, potentially through the release of pollutants into nearby water sources. This representation effectively highlights the diverse environmental impacts of human activities on both air and water quality, emphasizing the importance of responsible practices to mitigate these detrimental effects. Hence the correct option is 2.

Option 2 is correct. It directly links human activities to negative environmental consequences like sound pollution from airport construction and water contamination from power plant development.

Forest area cleared to construct an airport leading to an increase in sound pollution: This illustrates a direct impact of human activity on the environment. Clearing forests for infrastructure development like airports often leads to increased noise pollution due to aircraft operations and associated activities.

Vegetation cleared to construct a power plant leading to contamination of water: Again, this demonstrates a direct consequence of human activity. The clearance of vegetation for industrial purposes such as power plants can result in soil erosion and runoff, which may contaminate nearby water sources with sediments, chemicals, or pollutants.

Both of these impacts highlight tangible and negative consequences of human activities on the environment, emphasizing the importance of considering the environmental impacts of development and infrastructure projects. Therefore, option 2 effectively portrays the impacts resulting from human activities.

Complete Question:

Which table best shows the impacts resulting from human activity?

ANSWER

A. <AKC and <TKI

D. <IKR and <AKP

EXPLANATION

Vertical angles are also called X-angles.

They are angles in the opposite corners of a figure that looks like X.

From the diagram, the options that are vertical angles are:

A. <AKC and <TKI

D. <IKR and <AKP

The correct answers are A and D.

Answer:

A and D.

Step-by-step explanation:

A pair of angles are vertical if both measure the same and both are opposite by a vertex. Then, in the figure we have that

∠AKC and ∠TKI are vertical angles

∠AKP and ∠PKI are not vertical angles (∠PKI measures more than ∠AKP and these angles are not opposite by a vertex).

∠AKT and ∠PKC are not vertical angles (same reason as the second option).

∠IKR and ∠AKP are vertical angles.

Step-by-step explanation:

Given

[tex]\left[\begin{array}{ccc}-2&3&0\\-4&2&6\\6&-5&6\end{array}\right][/tex]

The product of 3x2 will be six.. We have a scalar which has to be multiplied by the matrix. The method of multiplying a scalar with a matrix is to multiply each element of the matrix by the scalar.  

After multiplication the matrix will be:

[tex]\left[\begin{array}{ccc}-12&18&0\\-24&12&36\\36&-30&36\end{array}\right][/tex]

So, B is the correct answer..

To solve this question, you need to perform a scalar multiplication of the matrix by 3*2. Scalar multiplication involves multiplying every element of the matrix by the scalar value.
First, let's find the scalar value:
3 * 2 = 6
Now, let's multiply every element in the matrix by the scalar value 6:
Original matrix:
[ -2,  3,  0 ]
[ -4,  2,  6 ]
[  6, -5,  6 ]
After scalar multiplication by 6:
[ -2*6,  3*6,  0*6 ]
[ -4*6,  2*6,  6*6 ]
[  6*6, -5*6,  6*6 ]
Performing the multiplication for each element gives us:
[ -12,  18,   0 ]
[ -24,  12,  36 ]
[  36, -30,  36 ]
The resulting matrix after multiplying by the scalar value of 6 is:
[ -12,  18,   0 ]
[ -24,  12,  36 ]
[  36, -30,  36 ]
So the correct answer to the given matrix question is the matrix displayed above.

Answer:

the equation of circle is x²  + y² + 6x - 24y + 128 = 0

Step-by-step explanation:

To find the general form of the equation of the circle with center A (-3, 12) and radius r=5,  we simply use this formula;

General Equation of a circle is   (x - a)²  +  (y-b)² = r²

(a,b) are the two point at the center of the circle which are (-3, 12)

which implies a = -3 and b = 12

r is the radius of the circle which is given as 5 from the above diagram

to get r², we simply square 5 and so r²  = 25

We can now plug in the values of our variables into the equation

(x - a)²  +  (y-b)² = r²

(x - [-3])²   +   ( y  -  12)²  =   5²

(x +3)²   +   ( y  -  12)²  =   5²

we will expand all the brackets

x² +  6x +  9  + y² -24y + 144 = 25

x² +6x + y² -24y + 153 = 25

Take 25 to the left hand side of the equation

x² +6x + y² -24y + 153  -  25 = 0

x² +6x + y² -24y + 128 = 0

Rearranging the equation to give us a standard form of the equation of the circle, we have;

x² + y² + 6x - 24y  + 128 =0

{Note:  (x + 3)²  =  (x+3)(x+3) = x² + 6x + 9 and  

(y - 12)²  = (y -12)(y-12) = y² - 24y + 144}

Therefore the general form of the equation  of a circle with center(-3, 12) and radius 5 is x² + y² + 6x - 24y  + 128 =0

If (x+k) is a factor of f(x), then -k is a root (or solution) of f(x).

Step-by-step explanation:

Where are the answer choices?  Please share them.

If (x+k) is a factor of f(x), then -k is a root (or solution) of f(x).

If (x+k) is a factor of f(x), then f(-k) = 0

from the question, we have the following parameters that can be used in our computation:

(x + k) is a factor of f(x)

If (x+k) is a factor of f(x), then f(-k) = 0. This is known as the factor theorem.

It states that if a polynomial f(x) has a factor of (x-a), then f(a) = 0.

In this case, since (x+k) is a factor of f(x), we can substitute -k for x in the factor theorem to get f(-k) = 0.

The slope intercept form of a line: y = mx + b

m - slope

b - y-intercept (0, b)

If m > 0, then the function is increasing

If m < 0, then the function is decreasing

==================================================

y = -2x - 1 → m = -2 < 0 and b = -1

decreasing function, y-intercept -1 → (0, -1)

y = x + 5 → m = 1 > 0 and b = 5

increasing function, y-intercept 5 → (0, 5)

y = 2x - 1 → m = 2 > 0, and b = -1

increasing function, y-intercept -1 → (0, -1)

y = -x + 5 → m = -1 < 0 and b = 5

decreasing function, y-intercept 5 → (0, 5)

From the picture we have

(1) increasing function and y-intercept 5 → y = x + 5
