Step-by-step explanation:

Answer: 9

Step-by-step explanation:

The value of functions g(f(4)) is 9, f(g(4))=9 and g(f(−1)) is 64

A relation is a function if it has only One y-value for each x-value.

The given functions are  f(x) = x − 7 and g(x) = x²

We have to find g(f(4))

Let us find f(4) = 4-7=-3

g(-3)=9

g(f(4)) = 9

f(g(4))=f(16)

f(g(4))=9

g(f(−1))= g(-8)

g(f(−1))=64

Hence, the value of functions g(f(4)) is 9, f(g(4))=9 and g(f(−1)) is 64

Answer:

Population density = [tex]148.22\ \text{people per square kilometer}[/tex]

Step-by-step explanation:

The attached figure shows the dimension of an island.

Population density is equal to total population per unit land area.

Firstly we will find the area of the triangle using Pythagoras theorem as follows :

[tex]H^2=B^2+P^2[/tex]

H is Hypotenuse, B is base and P is perpendicular

[tex]B=\sqrt{H^2-P^2} \\\\B=\sqrt{(18.5)^2-(11.1)^2} \\\\B=14.8\ km[/tex]

Area of triangle is given by :

[tex]A=\dfrac{1}{2}\times b\times P\\\\A=\dfrac{1}{2}\times 14.8\times 11.1\\\\A=82.14\ km^2[/tex]

[tex]\text{Population density}=\dfrac{\text{Total population}}{\text{land area}}\\\\=\dfrac{12175 }{82.14}\\\\=148.22\ \text{people per square kilometer}[/tex]

Hence, the population density is [tex]148.22\ \text{people per square kilometer}[/tex].

Answer:

( x + 4 ) ( 3x + 1 )

Step-by-step explanation:

→ Identify the product, sum & factors

Product = 4

Sum = 13

Factors = 4 & 1

3x² + 12x + x + 4

→ Factorise 3x² + 12x and x + 4

3x² + 12x ⇔ 3x ( x + 4 )

x + 4 ⇔ 1 ( x + 4 )

→ Take out the ( x + 4 ) as a factor and ( 3x + 1 )

( x + 4 ) ( 3x + 1 )

Answer:

B. 21.5

Step-by-step explanation:

Median is the center value in a list of numbers arranged in ascending order.

In this case, values given in the list are in increasing order ;

10 , 11, 12, 15, 19, 24, 27, 29, 33 ,38  --------identify the middle value

The middle position has two values , 19 , 24 ---------find the average

( 19+24 )/ 2

43 / 2 = 21.5

The median is 21.5 (answer choice B).

Choice A is incorrect because sum of middle values (43) divided by two is not 21.8 .It is 21.5

Choice C and D are incorrect because 19 and 24 are both at the middle of the list of numbers so to get the correct median you get the average of the two middle values.

Answer:

w = 3/4 or w = -1/4

Step-by-step explanation:

3l4w - 1l - 5 = 1

Add 5 to both sides.

3|4w - 1| = 6

Divide both sides by 3.

|4w - 1| = 2

Set the inside of the absolute value equal to 2 and -2.

4w - 1 = 2 or 4w - 1 = -2

Add 1 to both sides.

4w = 3 or 4w = -1

Divide both sides by 4.

w = 3/4 or w = -1/4

Check w = 3/4:

3l4w - 1l - 5 = 1

3|4(3/4) - 1| - 5 = 1

3|3 - 1| - 5 = 1

3|2| - 5 = 1

6 - 5 = 1

1 = 1

w = 3/4 works.

Check w = -1/4:

3l4w - 1l - 5 = 1

3|4(-1/4) - 1| - 5 = 1

3|-1 - 1| - 5 = 1

3|-2| - 5 = 1

3(2) - 5 = 1

6 - 5 = 1

1 = 1

w = -1/4 works.

There are no extraneous solutions.

Answer: w = 3/4 or w = -1/4

Reflection across the y-axis

Answer:

C. Its graph is symmetric about the y-axis

Step-by-step explanation:

I just took the pre-test

You can also graph the function and it is the same on both sides of the axis. For other questions like this I suggest: math-way

I was able to eliminate the first two answers using this website.

The characteristic of the cosine function is Its graph is symmetric about the y-axis.

cosine function formula in terms of sides of a right-angled triangle is written as:

cos x = Adjacent Side/Hypotenuse = Base/Hypotenuse, where x is the acute angle between the base and the hypotenuse.

Properties of cosine depend upon the quadrant in which the angle lies. The cosine function is a special trigonometric function and has many properties. Some of them are listed below:

As, The graphs of sine and cosine have the same shape: a repeating “hill and valley” pattern over an interval on the horizontal axis that has a length of .

Hence, the graph is  symmetric about the y-axis.

Problem 22

---------------------------------------

Explanation:

y = kx is the general form for direct variation. K is some constant.

Plug in (x,y) = (-3,5) to find k

y = kx

5 = k*(-3)

-5/3 = k

k = -5/3

-------------

The equation is y = (-5/3)x. Now plug in y = -1 to find x

y = (-5/3)x

-1 = (-5/3)x

(-5/3)x = -1

x = -1*(-3/5)

x = 3/5

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

Problem 23

---------------------------------------

Explanation:

Same idea as above. First we need to find k.

y = kx

-7 = k(-3) .... plug in x = -3 and y = -7

-3k = -7

k = 7/3

The equation is y = (7/3)x

-------------

We can use this to find y when x = 9

y = (7/3)x

y = (7/3)*9 .... plug in x = 9

y = 21

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

Problem 24

---------------------------------------

Explanation:

First find k

y = kx

25 = k*15

25/15 = k

5/3 = k

k = 5/3

The equation is y = (5/3)x

------------

Now find y when x = 6

y = (5/3)x

y = (5/3)*6

y = 10

Answer:

  24. 10

Step-by-step explanation:

In each case, multiply the old value of the variable of interest by the new/old ratio of the given variable values.

__

22. x = (-1/5)(-3) = 3/5

23. y = (9/-3)(-7) = 21

24. y = (6/15)(25) = 10

_____

The proportions can be written as either of ...

  newX/newY = oldX/oldY   ⇒   newX = (newY/oldY)(oldX)

or, the same thing with x and y interchanged:

  newY/newX = oldY/oldX   ⇒   newY = (newX/oldX)(oldY)

Answer:

All the ordered pairs (a,b) are

(0,5), (2,3), (4,1), (6,8), and (8,6).

Step-by-step explanation:

765ab4 to be divisible by 36, it must be divisible by both 9 and 4.

For any number to be divisible by 4, the last two digits of the number must be divisible by 4.

Here, the last two digits are b4, so as the number b4 is divisible by 4, b can be 0,2,4,6, and 8.

For any number to be divisible by 9, the sum of all the digit of the number must be divisible by 9.

Here, the sum of all the digits, S= 7+6+5+a+b+4=22+a+b.

Now, we have b={0,2,4,6, 8}

For b=0,

S=22+a+0=22+a which is a multiple of 9.

So, the possible value of the digit a :

a=5

So, (a,b)=(0,5)

For b=2,

S=22+a+2=24+a which is a multiple of 9.

So, the possible value of the digit a :

a=3

So, (a,b)=(2,3)

For b=4,

S=22+a+4=26+a which is a multiple of 9.

So, the possible value of the digit a :

a=1

So, (a,b)=(4,1)

For b=6,

S=22+a+6=28+a which is a multiple of 9.

So, the possible value of the digit a :

a=8

So, (a,b)=(6,8)

For b=8,

S=22+a+8=30+a which is a multiple of 9.

So, the possible value of the digit a :

a=6

So, (a,b)=(8,6)

Hence, all the ordered pairs (a,b) are

(0,5), (2,3), (4,1), (6,8), and (8,6).

Answer:

$115

Step-by-step explanation:

15x6=90

90+25=115

Answer:

A

Step-by-step explanation:

Remember that the sum of the interior angles of a triangle is always 180 degrees. We are given that two of the interior angles of the triangle are y and the exterior angle that is connected to the missing interior angle is 130 degrees. We can see from the image that the given exterior angle and the missing interior angle are supplementary, or they add up to 180. Knowing this, we can find the missing interior angle:

130 + a = 180

a = 50

So we now know that the missing interior angle is 50 degrees. Since the sum of the interior angles for a triangle is 180 degrees, we can make the equation:

50 + y + y = 180

and solve for y.

50 + y + y = 108

50 + 2y = 180

2y = 130

y = 65

So now we know that y = 65.
