The radius of the larger circle is 5m. The radius of the smaller circle is 2.5m. What’s the approximate area of the shaded region of the larger circle?

Answer:

none of the above

Step-by-step explanation:

4x + 7 = x + 2

4x - x + 7 = x - x + 2

3x + 7 = 2

3x + 7 - 7 = 2 - 7

3x = -5

3x / 3 = -5 / 3

x = -5 / 3 = -1.667

5x - 8 = x + 4

5x - x - 8 = x - x + 4

4x - 8 + 8 = 4 + 8

4x = 12

4x / 4 = 12 / 4

x = 3

3x + 2 = 5x + 2

3x - 5x + 2 = 5x - 5x + 2

-2x + 2 = 2

-2x + 2 - 2 = 2 - 2

-2x = 0

x = 0

Integers, As a whole number that can be written without a remainder,

x = 3

x = 0

(Mixed) Fraction

x = -5 / 3 = -1.667

The x-intercept is 4, and the asymptote is located at y = 3 , Option C is the correct answer.

An asymptote is a line that a curve approaches but it never reach.

The given equation

y = log₅(x-3)

To find the asymptote

Set the argument of the logarithm equal to zero.

x - 3 = 0

The vertical asymptote occurs at

x = 3

The equation can also be written as

[tex]\rm 5^y = x-3[/tex]

To find the x intercept we will put the value of y = 0 ;

therefore

5⁰ = x -3

1=x-3

x = 4

Therefore ,The x-intercept is 4, and the asymptote is located at y = 3 , Option C is the correct answer.

Answer:

E. 38°

Explanation:

A rhombus has 360° interior angle.

Half of the other side has 180° angle.

Solve for x:

sum of interior angles = 180°

x + 14 + x + 14 + x + x = 180°

4x + 28° = 180°

4x = 180° - 28°

4x = 152°

x = 152°/4 = 38°

Sum of half interior angles=180°

Answer:

45 minutes

Step-by-step explanation:

If you're trying to find the total number of minutes, they practiced you'd have to add.

So, if they did free throws for 17 minutes

Ran for 12 minutes

And passed the ball for 16

You'd add those up

17+16+12 = 45

In conclusion they practiced for a total of 45 minutes.

Why?

Notice that f(x) is positive when -2 < x < 1. In other words, f(x) is positive when x = -1 and when x = 1.

This interval of -2 < x < 1 translates directly to the interval notation of (-2, 1)

Unfortunately this interval notation looks identical to ordered pair notation. Be sure not to mix the two concepts up.

The parenthesis in interval notation tell the reader "do not include the endpoints". We cannot include x = -2 nor x = 1 because these values make f(x) zero, but we want f(x) > 0.

Something like choice D is a non-answer because the value x = 2 is in the interval (1,4), but f(2) = -8 which isn't positive. We can rule choice D out because of it. Choices A and C are similar situations.

The perimeter and area of this minor circle are equal to 32.857 units and 88.345 units² respectively.

First of all, we would determine the circumference of this circle by using this formula:

C = πD

C = 22/7 × 14

C = 44 units.

For the length of an arc of the circle:

Arc length/Circumference = 3/7

Arc length = 3/7 × C

Arc length = 3/7 × 44

Arc length = 18.857 units.

Now, we can calculate the perimeter:

Perimeter = 2r + arc length

Perimeter = 2(14/2) + 18.857

Perimeter = 14 + 18.857

Perimeter = 32.857 units.

Mathematically, the area of a minor circle is given by this formula:

Area = θr²/2

But, we would have to find the angle in radians:

18.857/32.857 = θ/360

θ = 3.6059 radians.

Substituting the given parameters into the formula, we have;

Area = (3.6059 × 7²)/2

Area = 88.345 units².

The algebraic rule that best describes the translation of quadrilateral ABCD to quadrilateral A'B'C'D' is P'(x, y) = (x + 8, y + 7). (Correct answer: A)

According to the image attached we understand that the quadrilateral ABCD is transformed into quadrilateral A'B'C'D' by applying pure translation. Translations are a kind of rigid transformation, defined as a transformation applied on a geometric locus such that Euclidean distance is conserved at every point of the construction.

Vectorially speaking, translations are described by the following formula:

P'(x, y) = P(x, y) + T(x, y)     (1)

Where:

By direct comparison, we conclude that the quadrilateral ABCD is translated 8 units in the +x direction and 7 units in the +y direction. Hence, the algebraic rule that describes the translation of quadrilateral ABCD to quadrilateral A'B'C'D' is:

P'(x, y) = (x, y) + (8, 7)

[tex]2\sqrt{5}[/tex] is an irrational number.

[tex](\sqrt{3} )^2[/tex] is a rational number.

Step-by-step explanation:

The solution to the equations are:

The equation is given as:

[tex]9x\² - 36x + 36 = 0[/tex]

The above equation is a quadratic equation which can be represented as:

[tex]ax\² + bx + c = 0[/tex]

The discriminant (d) is calculated as:

[tex]d = b\² - 4ac[/tex]

So, we have:

[tex]d = (-36)\² - 4 * 9 * 36[/tex]

[tex]d = 0[/tex]

A discriminant of 0 means that the equation has two equal real solutions

Hence, 9x² - 36x + 36 = 0 has two equal real solutions

The equation is given as:

[tex]x\² - x + 4 = 0[/tex]

The above equation can be represented as:

[tex]ax\² + bx + c = 0[/tex]

The discriminant (d) is calculated as:

[tex]d = b\² - 4ac[/tex]

So, we have:

[tex]d = (-1)\² - 4 * 1 * 4[/tex]

[tex]d = -15[/tex]

A discriminant of -15 means that the equation has no real solutions

Hence, x² - x + 4 = 0 has no real solutions

We have:

Evaluate the difference

[tex]4x\² -12[/tex]

Answer:

I guess, A is the wanted answer, but

A and D together are the really correct answer.

Step-by-step explanation:

if I understand this correctly, then

g(x) = sqrt(x - 3)

the domain of a function is the definition of all valid x (input) values.

the range of a function is the definition of all valid y (result) values.

well, the content (the arguments) of a square root cannot be negative (at least not while dealing with real numbers).

so, the answer options B and D are automatically out, because the domain contains values that would make the arguments of the square root negative.

I guess your teacher wants to focus only on the positive results of the square root, so A is the correct number.

BUT formally, without designated restrictions, a square root has always 2 solutions : a positive and a negative one.

because (-x)² = (x)² = x².

so, I would have to say that the really correct answer is

A + D, because the range contains both, the positive and the negative numbers.

The sentence "Four times the sum of a number and 17 is at least −26" translated to an inequality is 4(x+17) ≥ -26

From the question, we are to translate the given sentence into an equality.

The given sentence is

Four times the sum of a number and 17 is at least −26

Let the unknown number be x

Then,

The sum of a number and 17 will be

x + 17

Then,

Four times the sum of a number and 17 can be written as  

4(x+17)

Now,

"At least -26" means it is greater than or equal to -26

Thus,

Four times the sum of a number and 17 is at least −26 becomes

4(x+17) ≥ -26

From the question, we are to determine the formula that could be used to find area of the figure shaded green

From the formula for calculating area of a square

A = s²

Where A is area

and s is the side length

Then, the area of the bigger square will be

A = 9²

NOTE: Side length of the bigger square is 9m

Then,

For the smaller square, which is not shaded green

A = 4²
