Answer:

1/8 of a chance to flip 3 coins and get that exact combination in that order

Explanation:

a coin has 2 sides, heads and tails, with an equal chance to land on each of them. 1/2 chance to get tails on the first flip x  1/2 chance to get heads on the second flip x 1/2 chance to get tails on the third flip. 1/2 x 1/2 x 1/2 = 1/8.

The requried graph of the solution of a set of given inequality 13 > 5+ 4x is shown.

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

here,
Given inequality,
13 > 5 + 4x

Simplify the above expression,
Subtract -5 from both sides,
13  - 5 > 5 - 5 + 4x
8 > 4x

Divide by 4 into both sides
2 > x

The graph of the solution to the given inequality is less than 2, and line x = 2 will be a dotted line [value no included in x < 2]

Thus, the graph of the inequality has been shown.

The equation of the tangent line to the parabola at the point (1,5) is y = 4x + 1.

To find the slope of the tangent line to the parabola at the point (1,5), we need to find the derivative of the equation y = 6x - x² and evaluate it at x = 1.

Taking the derivative of y with respect to x:

dy/dx = d(6x - x²)/dx

= 6 - 2x

Now, we can substitute x = 1 into the derivative to find the slope at that point:

slope = 6 - 2(1)

= 6 - 2

= 4

So, the slope of the tangent line to the parabola at the point (1,5) is 4.

To find the equation of the tangent line, we need to use the point-slope form of a line.

The equation is given by:

y - y₁ = m(x - x₁)

Substituting the values we have:

y - 5 = 4(x - 1)

Expanding and simplifying:

y - 5 = 4x - 4

Moving the constant term to the other side:

y = 4x + 1

Therefore, the equation of the tangent line to the parabola at the point (1,5) is y = 4x + 1.

Answer:

c = 4

Step-by-step explanation:

Solve for c:

2 (c + 1) = 10

Divide both sides of 2 (c + 1) = 10 by 2:

(2 (c + 1))/2 = 10/2

2/2 = 1:

c + 1 = 10/2

The gcd of 10 and 2 is 2, so 10/2 = (2×5)/(2×1) = 2/2×5 = 5:

c + 1 = 5

Subtract 1 from both sides:

c + (1 - 1) = 5 - 1

1 - 1 = 0:

c = 5 - 1

5 - 1 = 4:

Answer: c = 4

Answer:

\(\boxed{\sf c=4}\)

Step-by-step explanation:

\(\sf 2(c+1)=10\)

Distribute:-

\(\sf 2c+2=10\)

Subtract 2 from both sides:-

\(\sf 2c+2-2=10-2\)

\(\sf 2c=8\)

Divide both sides by 2:-

\(\sf \cfrac{2c}{2}=\cfrac{8}{2}\)

\(\sf c=4\)

Therefore, c = 4!!!

The volume of a cone can be calculated using the formula V = (1/3)πr^2h, where r is the radius of the circular base, h is the height of the cone, and π is constant approximately equal to 3.14.

Substituting the given values, we get:

V = (1/3)π(18^2)(6) = 6,084π cubic inches

To find the fraction of the volume of the cone filled when the water reaches a height of 2 inches, we need to calculate the volume of water in the cone. The water will form a smaller cone with a height of 2 inches and a radius of 18 inches.

Using the same formula as above, we get:

V_water = (1/3)π(18^2)(2) = 648π cubic inches

The fraction of the volume of the cone filled with water is then:

V_water / V = (648π) / (6,084π) = 0.106, which is approximately equal to 1/9.

Therefore, the answer is C. 1/9.

The value of angle x will be 91° for the given triangle.

A triangle is a polygon with three sides, three vertices (corners), and three angles. The sum of the three angles in a triangle is always 180 degrees. Triangles are important in geometry and mathematics, and they have many applications in science, engineering, and everyday life.

Triangles can also be used to calculate the areas of various two-dimensional shapes and to solve problems related to distance, angles, and proportions.

Triangle fixed value = 180

x = 180 - (45 + 44)

x = 180 - 89

x = 91

Therefore, the value of x is 91°

The complete equation when the blanks are replaced is (a^2 + 3a + 1) - (-3a^2 + 5a - 6)=4a^2 - 2a + 7​

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

(a^2+blank+1)-(blank+5a+blank)=4a^2-2a+7​

By comparison, we have the following

a^2 - blank = 4a^2

blank - 5a = -2a

1 - blank = 7

When the above equations are solved, we have

blank = -3a^2

blank = 3a

blank = -6

So, we have

(a^2 + 3a + 1) - (-3a^2 + 5a - 6)=4a^2 - 2a + 7​

The unit tangent vector t(t) of the given vector function r(t) = (3t, 1 + 2t^2, t^2) is obtained by dividing the derivative of r(t) by its magnitude. The derivative of r(t) is (3, 4t, 2t), and the magnitude of this vector is sqrt(9 + 20t^2). Therefore, t(t) = (3, 4t, 2t) / sqrt(9 + 20t^2).

The unit normal vector n(t) can be obtained by dividing the derivative of t(t) by its magnitude. The derivative of t(t) is (3, 4, 2t), and the magnitude of this vector is sqrt(25 + 4t^2). Thus, n(t) = (3, 4, 2t) / sqrt(25 + 4t^2).

Answer: Rotation

Step-by-step explanation:

From the figure , we can observe that both figure A and b are absolutely congruent.

To translate a figure to make congruent images , we use rigid motions (Translation, Reflection, Rotation)

It is Rotation because of we move Figure A 180 degrees clockwise about the fixed point O, we will get Figure B .

It cannot be reflection because both figures are not mirror images.

It cannot be translation because all points on Figure A is not moving , as point O remained at same position throughout this which is not possible in translation.

The required simple interest would be the amount of 1,170€ on a 4500€ principal deposited for four years at a rate of 6.5%

We have been given data as:

Principal (P) = 4500€

Rate of Interest (R) = 6.5% = 6.5/100 = 0.065

Time (T) = 4 years

⇒ Simple interest  = P × R × T

Substitute the value of P, R, and T in the above formula,

⇒ Simple interest  = 4500 × 6.5% × 4

⇒ Simple interest  = 4500 × 6.5/100 × 4

⇒ Simple interest  = 4500 × 0.065 × 4

Apply the multiplication operation, and we get

⇒ Simple interest  = 1,170€

The value of x is equal to 15°

In Mathematics and Geometry, the sum of the exterior angles of both a regular and irregular polygon is always equal to 360 degrees.

Note: The given geometric figure (regular polygon) represents a pentagon and it has 5 sides.

By substituting the given parameters, we have the following:

3x + 4x + 8 + 5x + 5 + 6x - 1 + 5x + 3 = 360°.

3x + 4x + 5x + 6x + 5x + 8 + 5 - 1 + 3 = 360°.

23x + 15 = 360°.

23x = 360 - 15
