what is a factor of 18

From the given information provided, the first three common denominators of 7/9 and 2/3 are 9, 18, and 27.

To find the common denominators of 7/9 and 2/3, we need to find the least common multiple (LCM) of their denominators.

The prime factorization of 9 is 3 x 3, and the prime factorization of 3 is 3.

The prime factorization of 2 is 2, and the prime factorization of 3 is 3.

The common factors are 3, so the LCM of 9 and 3 is 9.

Therefore, the common denominator of 7/9 and 2/3 is 9.

To find the next two common denominators, we can continue to find the LCM of the denominators with the added factor of 9.

The prime factorization of 18 (2 x 3 x 3) includes the prime factors of 9, so it is a common denominator.

The prime factorization of 27 (3 x 3 x 3) also includes the prime factors of 9, so it is another common denominator.

The slope of the line tangent to the parabola's y-intercepty = [tex](x+2)^2-4[/tex] is 4.

We must first get the parabola's y-intercept in order to determine the slope of the line tangent to it.

We enter x=0 into the equation to obtain the y-intercept:

[tex]y = (x + 2)^2 - 4[/tex]

[tex]y = (0 + 2)^2 - 4[/tex]

y = 4 - 4

y = 0

Hence, the parabola's y-intercept is (0, 0).

The derivative of the parabola's equation must then be determined.

[tex]y = (x + 2)^2 - 4\\y = x^2 + 4x + 4 - 4\\y = x^2 + 4x[/tex]

dy/dx = 2x + 4

By adding x=0 to the derivative, we can now get the slope of the tangent line to the y-intercept:

dy/dx = 2x + 4

dy/dx = 2(0) + 4

dy/dx = 4

Hence, the slope of the line tangent to the parabola's y-intercepty = [tex](x+2)^2-4[/tex] is 4.

The equation for the calculation of the score will be 6-x , where x is the number of birdies (negetive score).

Lets suppose the number of birdies that have been scored is "x" . And since birdie is a negetive score, everytime we score a birdie, we need to reduce 1 from the standing score i.e. to say the total number of birdies is needed to be subustracted from the current score.

Score = Initial Score - Number of birdies

Answer:

35 degrees

Step-by-step explanation:

The direction "North" is parallel to itself, because of the reflexive property of parallel lines. Using the alternate interior angles theorem, the measure of x + 25 must be equal to 60 degrees. 60 - 25 = 35

Answer:

x = 35°

Step-by-step explanation:

The angle made by the directional line from wharf to Shell Cove relative to North is 60° at the point of departure from the wharf

The angle that this same line makes at the point of arrival at Shell Cove must be 60° relative to North since the two North directions are perpendicular and the line connecting the wharf and shell cove is a transversal intersecting these lines

This is because of the property that when two parallel lines are intersected by a transversal, the alternate interior angles must be the same

The angle made by this transversal at Shell Cove = x + 25 degrees

Since (x + 25)° = 60°

x = 60° - 25°

x = 35°

Using the theorem of angle around a point, the value of GHJ is 237 degrees

When we talk about the "angle around a point," we are usually referring to the total angle formed by two or more lines or line segments that intersect at a common point, known as the vertex.

Specifically, the "angle around a point" is equal to 360 degrees or 2π radians. This is because, when two or more lines intersect at a point, they form multiple angles, and the sum of these angles is always equal to 360 degrees or 2π radians.

Since we know that FPJ and JPI are congruent, this implies that they're equal to one another. We can find the value by setting them as x

x + x + 51 + 66 + 99 = 360

Reason: The sum of angles around a point is equal to 360 degrees

2x + 216 = 360

2x = 360 - 216

2x = 144

x = 72

a. To find the angle QCP, we can start by finding the coordinates of the points P, Q, and C. Since P and Q are midpoints of the edges FG and GH, respectively, we can find their coordinates as follows:

P = (0, y, z) where y = (3+4)/2 = 3.5 and z = (0+4)/2 = 2

Q = (x, y, 0) where x = (3+4)/2 = 3.5 and y and z are the same as before.

Since C is the center of the cube, we can find its coordinates as:

C = (2, 2, 2)

Now we can use the dot product formula to find the angle QCP:

cos(QCP) = (PC · QC) / (|PC| · |QC|)

where PC and QC are the vectors from P to C and from Q to C, respectively.

PC = C - P = (2, 2 - 3.5, 2 - 2) = (2, -1.5, 0)

QC = C - Q = (2 - 3.5, 2 - 3.5, 0) = (-1.5, -1.5, 0)

|PC| = sqrt(2² + (-1.5)² + 0²) = sqrt(5.25)

|QC| = sqrt((-1.5)² + (-1.5)² + 0²) = sqrt(4.5)

PC · QC = 2(-1.5) + (-1.5)(-1.5) + 0 = -3 + 2.25 = -0.75

cos(QCP) = (-0.75) / (sqrt(5.25) * sqrt(4.5)) = -0.166666...

Therefore, the angle QCP is cos⁻¹(-0.166666...) ≈ 100.53° (rounded to two decimal places).

b. To find the total surface area of the solid remaining after pyramid PGQC is removed, we need to find the area of the four triangular faces and the square base of the pyramid and subtract them from the total surface area of the cube.

The square base of the pyramid has side length PQ = sqrt((3.5 - 3)² + (3.5 - 4)² + 2²) = sqrt(2.5) and area PQ² = 2.5 cm².

Each of the triangular faces has base PQ and height equal to the distance from P or Q to the plane containing the opposite vertex and the center of the cube. This distance is equal to the length of the perpendicular from the vertex to the opposite face, which is half the length of the diagonal of the cube.

The diagonal of the cube is sqrt(3² + 4² + 4²) = sqrt(41), so the height of each triangular face is sqrt(41)/2.

Therefore, the area of each triangular face is (1/2)PQ(sqrt(41)/2) = (sqrt(41)/4) cm².

The total surface area of the cube is 6s², where s is the length of a side of the cube. Since the volume of the cube is 1728 cm³, we have s³ = 1728, or s = 12 cm.

Therefore, the total surface area of the cube is 6(12²) = 864 cm².

The total surface area of the solid remaining after the pyramid is removed is:

Answer:

0 triangles can be formed

Step-by-step explanation:

In order to determine the number of distinct triangles that can be formed with the given information, we need to apply the triangle inequality theorem. According to this theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Let's start by drawing a rough sketch of the triangle:

     Z

     |\

     | \

     |   \ x

     |     \

     |       \

     X-----Y

      y=2

We know that mZX = 51°, so we can label that angle on our diagram:

     Z

     |\

     | \

     |   \ x

     |     \

     |51°  \

     X-----Y

      y=2

We can use the sine law to find the length of side XY:

sin(51°) = XY / 5

XY = 5 * sin(51°)

XY ≈ 3.95

Now we need to check whether XY is less than the sum of the other two sides, XZ and YZ:

XZ + YZ > XY

2 + √(x² - XY²) > XY

2 + √(5² - 3.95²) > 3.95

2.86 > 3.95 (false)

Since XY is greater than the sum of the other two sides, it is not possible to form a triangle with the given measurements. Therefore, the number of distinct triangles that can be formed is 0.

The function that satisfies the differential equation y′ = -2 with initial condition y(0) = -8 is y = -2x - 8.

To solve the differential equation y′ = -2 with initial condition y(0) = -8, we need to find the function y(x) that satisfies both the differential equation and the initial condition.

We can start by integrating both sides of the differential equation with respect to x:

∫y′ dx = ∫(-2) dx

y = -2x + C

where C is a constant of integration.

To find the value of C, we can use the initial condition y(0) = -8:

y(0) = -2(0) + C = C = -8

So the solution to the differential equation with initial condition is:

y = -2x - 8

Answer:

Step-by-step explanation:

To find the amount Rob will have in 5 years with compound interest, we can use the formula:

A = P (1 + r/n)^(nt)

where:

A = the future value of the investment

P = the principal amount invested

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

In this case, we have:

P = $7,869 (the principal amount)

r = 13% or 0.13 (the annual interest rate)

n = 1 (the interest is compounded annually)

t = 5 (the number of years)

Substituting these values into the formula, we get:

A = $7,869 (1 + 0.13/1)^(1*5)

A = $7,869 (1.13)^5

A = $14,964.92

Therefore, to the nearest cent, Rob will have $14,964.92 in 5 years.
