What is the value of f(6) in the function below? f(x)=2^x

A. 16

B. 32

C. 12

D. 64

Answer:

(5, 8)

Step-by-step explanation:

f(x) + 4 is the graph of f(x) translated 4 units vertically up

given (5, 4) is a point on f(x), then the coordinates of the corresponding point

x- coordinate remains unchanged and add 4 to the y- coordinate

The corresponding point on f(x) + 4 is (5, 4 + 4) = (5, 8)

Complex numbers are numbers in which the real component and the imaginary part of the number are both represented. The numbers in standard form will be a + bi, where a is the real part and bi is the imaginary part. An example of a complex number would be 3 +5i. 3 is the real part, and 5i is the imaginary part.

The complex number 3cis210 can be written in standard form as - (3√3/2)i - (3/2).

The complex number 3cis210 can be written in standard form as:

3cis210 = 3(cos(210°) + i sin(210°))
Using the trigonometric identities cos(210°) = -√3/2 and sin(210°) = -1/2, we can simplify:

3cis210 = 3(-√3/2 + i(-1/2))

Therefore, the complex number 3cis210 in standard form is - (3√3/2)i - (3/2).

Answer:

Simplifying the equation:

[tex]\frac{2}{3} x - \frac{5}{6} = -\frac{5}{12} x + \frac{1}{4}[/tex]

Grouping like terms:

[tex]\frac{2}{3} x + \frac{5}{12} x= \frac{1}{4} + \frac{5}{6}[/tex]

⇒ [tex]\frac{39}{36} x=\frac{26}{24}[/tex]

Solving for 'x', we have:

⇒ [tex]x=\frac{26}{24}\frac{36}{39}=1[/tex]

For this case we place the terms with "x" on the left side of the equation, and the terms without "x" on the right side:

[tex]\frac {2} {3} x + \frac {5} {12} x = \frac {1} {4} + \frac {5} {6}[/tex]

We add similar terms:

[tex]\frac {24 + 15} {36} x = \frac {6 + 20} {24}\\\frac {39} {36} x = \frac {26} {24}[/tex]

We simplify both sides:

[tex]\frac {13} {12} x = \frac {13} {12}[/tex]

Dividing by [tex]\frac {13} {12}[/tex] on both sides of the equation:[tex]x = 1[/tex]

In a mapping diagram, a relation that is a function can have two arrows coming from the same input value

false

Answer: False.

Step-by-step explanation:

By definition, a relation is a function if each input value has only one output value.

Knowing this, we can say that in a mapping diagram, a function will never have two arrows coming from the same input value.

 In other words, if in a mapping diagram a relation has two arrows coming from the same input value, this means that this input value has two output values, and according to the definition mentioned above, this relation cannot be a function.

Therefore, the statement "In a mapping diagram, a relation that is a function can have two arrows coming from the same input value", is FALSE.

Answer:

[0,∞), {y|y≥0}

Step-by-step explanation:

The graph of y =|3x + 1| is attached.

By observation, we can see that the the least y-value that the graph can take is y =0 (i.e the x-axis) and the greatest y-value that the graph can take is positive infinity.

Hence the range is [0,∞), {y|y≥0}

Final answer:

The range of the function y = |3x + 1| is [0, infinity), as absolute value functions always yield non-negative values.

Explanation:

The range of the function y = |3x + 1| can be determined by understanding the behavior of absolute value functions. The absolute value function |x| always yields a non-negative value. Therefore, for any real number x, |3x + 1| will also be non-negative. Hence, the range of y = |3x + 1| is [0, ∞), meaning that y can be any real number greater than or equal to zero.

Answer: 4.24264069

Step-by-step explanation: I think you mean the square root?

Answer:

x = -1, 1, -5 , 5.

Step-by-step explanation:

x4 – 26x2 + 25 = 0

Factoring:

(x^2 - 25)(x^2 - 1) = 0

So x^2 - 25 = 0 gives x^2 = 25 and x = +/- 5.

x^2 - 1  gives  x^2 = 1 and x = +/- 1.

Follow below steps:

To solve the equation x4 − 26x2 + 25 = 0, we can use substitution to simplify the equation. Let's set u = x2, which turns our equation into a quadratic form: u2 − 26u + 25 = 0.

Now, we apply the quadratic formula where a = 1, b = -26, and c = 25 to find the values of u. The quadratic formula is u = (-b ± √(b2 - 4ac))/(2a). Substituting the values, we get the roots for u which are u = 25 and u = 1.

Now we substitute back for x by setting x2 = u, which gives us two separate equations to solve: x2 = 25 and x2 = 1. Solving these, we find the solutions for x to be x = 5, x = -5, x = 1, and x = -1.

Answer:

Z°= 88.36

Tan-1×35=88.36

Answer:

z = 38 degrees

Step-by-step explanation:

As we can see in the picture that the triangle is a right angle triangle and two of the angles are known.

We also know that the sum of internal angles of a triangle is 180 degrees.

We know that one angle is 90 degrees and second is 52 degrees.

So,

Sum of three angles = 180 degrees

90 + 52 + z = 180

z = 180 - 90 - 52

z = 38 degrees ..

Answer:

(x+1)^2+(y+4)^2=9

Step-by-step explanation:

First equation in what I like to call center-radius form is (x-h)^2+(y-k)^2=r^2 where (h,k) is center and r is radius.

So we are given (h,k)=(-1,-4) so we have so far that

(x+1)^2+(y+4)^2=r^2

Passes through the point (-1,-1) means at some point (x,y) takes on the point (-1,-1) so guess what we are going to find r^2 by plugging in that point where x and y are.

(-1+1)^2+(-1+4)^2=r^2

(0)^2+(3)^2=r^2

9=r^2

so the equation of the circle is (x+1)^2+(y+4)^2=9

Answer:

(x + 1)² + (y + 4)² = 9

Step-by-step explanation:

The equation of a circle is:

(x - h)² + (y - k)² = r²

where (h, k) is the center and r is the radius.

The center is (h, k) = (-1, -4).  The radius is the distance from the center to any point on the circle.  (-1, -1) is 3 units above the center, so r = 3.

(x + 1)² + (y + 4)² = 9

Slope of JK = -4/5

Step-by-step explanation:

We know that GHJK is a parallelogram. If GHJK is a parallelogram then the sides of parallelogram will be:

GH, HJ, JK, GK

Hence the opposite sides will be:

GH and JK

HJ and GK

We know that opposite sides of parallelogram are parallel to each other and the slopes of parallel lines is equal.

So the slope of GH and JK will be equal.

And slopes of HJ and GK will be equal.

As we are given the slope of GH which is -4/5, the slope of JK will also be -4/5 because both lines are parallel.

Answer:

96

Step-by-step explanation:

If m - n = 2, then 4m - 4n = 4(m - n) = 4(2).

Then (4x + 2y)(4m - 4n) equals (4x + 2y)(8), or 8(4x + 2y).

But we are told that 2x + y = 6.  Multiplying all terms by 2, we get

4x + 2y = 12.  Substituting 12 for 4x + 2y, we get our final answer:

(4x + 2y)(4m - 4n) equals (4x + 2y)(8), or 8(4x + 2y), or 8(12) = 96

Answer:

96

Step-by-step explanation:

(4x + 2y)(4m - 4n) = ?

We have an equation

2x+y =6

Multiply it by 2

2(2x+y) = 2*6

Distribute

4x+2y = 12

Substitute 12 in for 4x+2y into the original problem

12(4m - 4n) = ?

We have an equation

m-n = 2

Multiply this by 4

4(m-n) = 4*2

Distribute

4m-4n = 8

Substitute 8 in for 4m -4n in 12(4m - 4n) = ?

12 * 8 = ?

96

For this case we have that if two lines are perpendicular, then the product of their slopes is -1.

If we have the following equation of the line:

[tex]y = -4x + 9[/tex]

The slope is [tex]m_ {1} = - 4[/tex]

Then yes:

[tex]m_ {1} * m_ {2} = - 1\\m_ {2} = \frac {-1} {m_ {1}}\\m_ {2} = \frac {-1} {- 4}\\m_ {2} = \frac {1} {4}[/tex]

The equation of the new line will be:

[tex]y = \frac {1} {4} x + b[/tex]

We substitute the point to find "b":

[tex]5 = \frac {1} {4} (4) + b\\5 = 1 + b\\b = 5-1\\b = 4[/tex]

Finally, the equation is:

[tex]y = \frac {1} {4} x + 4[/tex]

Answer:

[tex]y = \frac {1} {4} x + 4[/tex]

Answer:  x = 7

`Step-by-step explanation:

Because the figure shows two triangles that are similar. we can write and solve an equation of ratios:

 9 cm       72 cm

----------- = -----------

3x - 20      56 cm

Cross-multiplying, we get (3x - 20)(72 cm) = (9 cm)(56 cm) = 504 cm²

Dividing both sides by 72 cm, we get:

3x - 20 = (504 cm²) / (72 cm) = 7

Then 3x - 20 = 7, and 3x = 27.  Then x must be 9.

The value of x in the triangle with parallel lines is 9.

To find the value of x in the equation involving a triangle with parallel lines, we can start by simplifying the equation and then solve for x.

The given equation is:

9/72 = (3x - 20)/56

Let's first simplify the left-hand side of the equation:

9/72 = 1/8

Now, the equation becomes:

1/8 = (3x - 20)/56

To isolate x, we can cross-multiply:

1 * 56 = 8 * (3x - 20)

56 = 24x - 160

Next, add 160 to both sides of the equation:

56 + 160 = 24x

216 = 24x

Finally, divide both sides by 24 to solve for x:

x = 216/24

x = 9

So, the value of x in the given equation is 9.
