The ASA (Angle-Side-Angle) postulate is a statement about the relationship between the angles and sides of triangles. It states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent. In other words, if two triangles have the same shape and size, then they are congruent.

CPCTC stands for "Corresponding Parts of Congruent Triangles are Congruent." This theorem states that if two triangles are congruent, then all their corresponding parts are congruent. In other words, if two triangles have the same shape and size, then all their angles and sides are congruent.

Answer:

The exponential growth function for the population can be written as:

P(t) = P0 * e^(rt)

Where:

P0 = initial population = 8,000

r = annual growth rate = 4.3% = 0.043

To find the monthly rate, we need to divide the annual rate by 12 (since there are 12 months in a year):

r_monthly = r/12 = 0.043/12 = 0.00358

So the exponential growth function with monthly growth rate becomes:

P(t) = 8000 * e^(0.00358t)

To find the quarterly rate, we need to divide the annual rate by 4 (since there are 4 quarters in a year):

r_quarterly = r/4 = 0.043/4 = 0.01075

So the exponential growth function with quarterly growth rate becomes:

P(t) = 8000 * e^(0.01075t)

The distance covered is. 90 miles

Speed is the distance an object travels in a given time.

This is represented as

Speed = Distance ÷ Time

We can also use the speed formula to calculate the distance or time by substituting the known values in the formula for speed and further evaluating,

Distance = Speed × Time or,

Time = Distance/Speed

To find the distance covered, we find the total speed

= 5 + 10(twice as fast on the trip back)

= 15

Distance = speed x time

= 15mph x 6hours

Answer: Let's call the number of bananas your character slipped on as "x". Then, the total points from slipping on bananas would be -3x. And since the total points from slipping on bananas during one race were at most -27, we can write an inequality to represent this:

-3x ≤ -27

Now we'll solve for x:

Divide both sides by -3:

x ≥ 9

So, the least number of bananas your character slipped on is 9.

To find the least number of seconds of race time, we need to multiply the number of bananas by 2 seconds per banana:

9 bananas * 2 seconds/banana = 18 seconds

So, the least amount of race time your character took to slip on bananas is 18 seconds.

The area of the parallelogram is 27 square centimeters.

A region's size on a surface is determined by its area. The area of an open surface or the boundary of a three-dimensional object is referred to as the surface area, whereas the area of a plane region or plane area refers to the area of a form or planar lamina. Area might be thought of as how much material of a certain thickness would be required to create a model of the shape, or as how much paint would be required to completely cover the surface in a single application.

The area of the parallelogram is given as:

A = (b)(h)

Here, the base is 4.5cm and the height is 6 cm.

Thus,

A = (4.5)(6)

A = 27 square centimeters.

Answer:

x = 15.25

y = 71/6

Step-by-step explanation:

10x -9y = 46

-2x + 3y = 5

Time the second equation by 5

10x - 9y = 46

-10x + 15y = 25

6y = 71

y = 71/6

Now put 71/6 back in for y and solve for x

10x -9(71/6) = 46

10x -106.5 = 46

10x = 152.5

x = 15.25

Let's check

-2(15.25) +3(71/6) = 5

-30.5 + 35.5 = 5

5 = 5

So, x = 15.25 and y = 71/6 is the correct answer.

The equation of the ellipsoid is[tex]\frac{x^{2} }{a^{2} } + \frac{y^{2} }{b^{2} } +\frac{z^{2} }{c^{2} } =1[/tex]

The equation of an ellipsoid is represented as:

[tex]\frac{x^{2} }{a^{2} } +\frac{y^{2} }{b^{2} } +\frac{z^{2} }{c^{2} } =1[/tex]

Given that the ellipsoid passes through the points (±6,0,0),(0,±7,0) and (0,0,±5)

It means that:

(±a,0,0)  = (±6,0,0)

(0,±b,0) = (0,±7,0)

(0,0,±c) = (0,0,±5)

By comparison, we have:

±a=±5

±b=±6

±c=±7

So, the equation of the ellipsoid becomes:

[tex]\frac{x^{2} }{a^{2} } +\frac{y^{2} }{b^{2} } +\frac{z^{2} }{c^{2} } =1[/tex]

[tex]\dfrac{9}{12} - \dfrac{11}{18} = \dfrac{5}{36}[/tex]

Step-by-step explanation:

We can solve this subtraction of fractions by converting both fractions to forms where they have a common denominator.

To do this, we first have to find the least common multiple (LCM) of their denominators.

    1. Write out the denominators' prime factorizations.

    12           18

    2, 2, 3     2, 3, 3

    2. Multiply the greatest multiple of each prime number.

    2² × 3² = 4 × 9 = 36

So, the LCM of the denominators is 36.

Next, we need to get both fractions' denominators to 36 by multiplying each one by {36 divided by them} over {36 divided by them}.

Remember, this is just multiplying by 1.

[tex]\left(\dfrac{9}{12} \times \dfrac{36/12}{36/12}\right) - \left(\dfrac{11}{18} \times \dfrac{36/18}{36/18}\right)[/tex]

The required slope of the linear function is $30, and the y-intercept is $75.

When you know the slope of the line to be investigated and the given point is also the y intercept, you can utilize the slope intercept formula, y = mx + b. (0, b). The y value of the y intercept point is denoted by the symbol b in the formula.

To find the slope of the linear function, we need to calculate the change in cost divided by the change in time.

Change in cost = $285 - $105 = $180

Change in time = 7 - 1 = 6

Slope = Change in cost / Change in time = $180 / 6 = $30

To find the y-intercept, we can use the point-slope form of a linear equation, y = mx + b, where y is the cost, x is the time, m is the slope, and b is the y-intercept.

Using the point (1, $105), we can substitute x = 1 and y = $105 into the equation and solve for b:

$105 = $30(1) + b

b = $105 - $30 = $75

Therefore, the slope of the linear function is $30, and the y-intercept is $75.

The linear function can be written as: y = $30x + $75, where x is the number of months of membership and y is the cost of the membership.

The moment of inertia (I) is a measure of an object's resistance to rotational motion around an axis. The moment of inertia of a cylinder can be calculated using the following formula:

I = (1/2) × m × r²

where:

I is the moment of inertia of the cylinder

m is the mass of the cylinder

r is the radius of the cylinder.

Here are the steps to calculate the moment of inertia for a cylinder:

Determine the mass of the cylinder. This can be done by weighing the cylinder on a scale or by using its density and volume. The formula for the mass of a cylinder is:

m = density × volume

Measure the radius of the cylinder. This is the distance from the center of the cylinder to its outer edge.

Substitute the values of m and r into the moment of inertia formula:

I = (1/2) × m × r²

Calculate the moment of inertia using a calculator.

Note that the moment of inertia of a hollow cylinder is different from that of a solid cylinder. To calculate the moment of inertia of a hollow cylinder, you need to subtract the moment of inertia of the hollow space from the moment of inertia of the solid cylinder using the parallel axis theorem.

A dot to the right of a note lengthens it by half of its original value in music notation.

A whole note that has a dot to the right of it is referred to as a dotted whole note. Whole notes typically receive 4 beats.

The note's overall duration is 4 + 2 = 6 beats after the dot adds the note's original duration by half.
