Answer:

The range of the function will be: {-9, -5, -1, 3, 7}

Step-by-step explanation:

Given the function

f(x) = 2x - 1

Given that the domain of the function is:

{-4, -2, 0, 2, 4}

Putting x=-4

f(x) = 2x - 1

f(-4)= 2(-4)-1=-8-1=-9

Thus,

at x=-4, y = -9

Putting x=-2

f(x) = 2x - 1

f(-2)= 2(-2)-1=-4-1=-5

Thus,

at x=-2, y = -5

Putting x=0

f(x) = 2x - 1

f(0)= 2(0)-1=0-1=-1

Thus,

at x=-2, y = -1

Putting x=2

f(x) = 2x - 1

f(2)= 2(2)-1=4-1=3

Thus,

at x=-2, y = 3

Putting x=4

f(x) = 2x - 1

f(4)= 2(4)-1=8-1=7

Thus,

at x=-2, y = 7

We also know that the range of a function is the set of values of the dependent variable for which a function is defined.

Thus, the range of the function will have all the y values correspond to all the x values for which the function is defined.

Thus, the range of the function will be: {-9, -5, -1, 3, 7}

Answer:

82.6666666667 or just 82.67

Step-by-step explanation:

The value of 248 ÷ 3 equals 82.

To divide 248 by 3, we set up the division equation: 248 ÷ 3.

Starting with the first digit of 248, which is 2, we check how many times 3 can be divided evenly into 2. Since 3 is larger than 2, we move on to the next digit, 24.

Now, we divide 24 by 3, which gives us 8.

Next, we bring down the next digit, 8, making the current dividend 88.

We divide 88 by 3, resulting in a quotient of 29.

Since there are no more digits to bring down, the division is complete.

Therefore, 248 ÷ 3 equals 82.

Answer:

[tex]\frac{X}{UB} = H[/tex] is the answer.

Step-by-step explanation:

Since we are solving for H, we need to get rid of everything that isn't H.

X = UHB can also be shown as X = UBH

Divide by UB on both sides to equal to H.

[tex]\frac{X}{UB} = H[/tex]

This is your answer.

This isn't an identity, so I assume you have to solve the equation.

(1 - sin(2A)) (1 + cot(2A)) = cot(2A)

1 - sin(2A) + cot(2A) - sin(2A) cot(2A) = cot(2A)

1 - sin(2A) - cos(2A) = 0

sin(2A) + cos(2A) = 1

Multiply both sides by 1/√2, which we want to do because cos(π/4) = sin(π/4) = 1/√2. This gives

cos(π/4) sin(2A) + sin(π/4) cos(2A) = 1/√2

Then condense the left side as

sin(2A + π/4) = 1/√2

2A + π/4 = sin⁻¹(1/√2) + 2nπ  or   2A + π/4 = π - sin⁻¹(1/√2) + 2nπ

(where n is any integer)

2A + π/4 = π/4 + 2nπ  or   2A + π/4 = 3π/4 + 2nπ

2A = 2nπ  or   2A = π/2 + 2nπ

A = nπ  or   A = π/4 + nπ

Answer:

V = 36π cubic inches.

Step-by-step explanation:

Given that:

The volume of the sphere is [tex]V = \dfrac{4}{3} \pi r^3[/tex]

If the diameter is represented by P.

Then P = 2r

and r = P/2

∴

[tex]V = \dfrac{4}{3} \pi ( \dfrac{P}{2})^3[/tex]

By differentiating both sides;

[tex]dV = \dfrac{4}{3} \pi \times 3 ( \dfrac{P}{2})^2 \times \dfrac{1}{2} \times dP[/tex]

[tex]dV = \dfrac{1}{2} \pi P^2 \ dP[/tex]

where;

P = 12

dP = 12.5 - 12

dP = 0.5

Then;

[tex]\dfrac{1}{2} \pi ( 12)^2 \times 0.5[/tex]

= 36π

Thus, the volume is V = 36π cubic inches.

Answer:

2(17-27x)

Step-by-step explanation:

Since the question was incomplete this is the only answer I have for you.

If you were looking for the answer of X I would need a answer for the equation

Anyways... you want to factor out 2 from the expression since there are two numbers

Once you factored out the two (divide each number by 2) you'll get:

2(17-27x)

Answer:

The answer is 34-54x because there are no like terms. 34 has no like terms and neither does 54x, so the answer is just 34-54x.

Answer:

The result of the correct substitution gives:

x = 3/7 and y = 27/7

Step-by-step explanation:

From the given information:

y = 2x + 3  ---- (1)

3x + 2y = 9 ---- (2)

By using substitutional method

Substitute the value of y = 2x +3 into equation (2)

So,

3x + 2(2x + 3) = 9

3x + 4x + 6 = 9

7x = 9 - 6

7x = 3

x = 3/7

From equation (1), let replace the value of  x  to be 3/7

So,

y = 2x + 3

y = 2(3/7) + 3

y =  6/7 + 3

y = 27/7
