Short Answers:

Answer for part A: Definition of perpendicular
Answer for part B: Right Angle Congruence Theorem
Answer for part C: Reflexive Property of Congruence
Answer for part D: Definition of Midpoint
Answer for part E: \triangle SXR \cong \triangle TXR
Answer for part F: CPCTC

-------------------------------------------------------------

Explanations:

Part A:

We are given that \overline{RX} \perp \overline{ST} which means, in english, "line segment RX is perpendicular to line segment ST"

By the very definition of perpendicular, this means that the two line segments form a right angle. This is visually shown as the red square angle marker for angle RXT. Angle RXS is also a right angle as well.

---------------------
Part B:

The Right Angle Congruence Theorem (aka Right Angle Theorem) is the idea that if we have two right angles, then we know that they are both 90 degrees so they must be congruent to one another. 

---------------------
Part C:

Any line segment is congruent to itself. This is because any line segment will have the same length as itself. It seems silly to even mention something so trivial but it helps establish what we need for the proof. 

---------------------
Part D:

We are given "X is the midpoint of segment ST" so by definition, X is in the very exact middle of ST. Midpoints cut segments exactly in half. SX is one half while TX is the other half. The two halves are congruent which is why SX = TX

---------------------
Part E:

Writing \triangle SXR \cong \triangle TXR means "triangle SXR is congruent to triangle TXR". These two triangles are the smaller triangles that form when you draw in segment RX

Side Note: SAS stands for "side angle side". The angle must be between the two sides. The pairing RX and RX forms one of the 'S' letters (see part C), while the pairing SX and TX forms the other 'S' (see part D). The angles between the sides are RXS and RXT (see part B). 

---------------------
Part F:

CPCTC stands for "Corresponding Parts of Congruent Triangles are Congruent"

It means that if we have two congruent triangles, then the corresponding parts are congruent. Back in part E, we proved the triangles congruent. For this part, we look at the pieces RS and RT (which correspond to one another; they are the hypotenuse of each triangle). They are proven congruent by CPCTC

If CPCTC is an odd concept to think about, then try thinking about something like this: you have two houses which are completely identical in every way. We can say that those two houses are congruent. If the houses are identical, then surely every piece that makes up the house is identical to its corresponding piece to the other house. For example, the front door to each house is both the same size, shape, color, made of the same material, designed in the same pattern, etc. So the two doors are congruent as well.

A number is decreased by seven. Then, the new number is multiplied by 3 to get an answer of -9. What is the original number? A.
rusak2 [61]

Answer:

The answer is c

Step-by-step explanation:

You have to do everything backwards,

-9 divide it by 3 to get -3, then add seven to that answer

Which is the greatest common factor of 8x7, and 24x5y3
Doss [256]

Answer:

You would be correct the GCF is 8x^5.

Step by Step Explanation:

So the GCF is basically a value that can go into or be factored out of two or more other numbers.

For instance, the greatest common factor of 10 and 20 is 10, since 10 is the greatest number that goes into 10 and 20 resulting in a integer.

Its a bit different with variables and exponents.

For instance, normally a number needs to be able to be divided nicely by the GCF. In exponents, the lowest exponent is the one you use.

If you had x^4 x^6 x^8, the GCF is x^4. It doesnt need to divide each exponent, but needs to be able to be subtracted by it,

You can think of it like how division and multiplication works with exponents.

With variables, it is similar to normal numbers.

The coefficent of the GCF must go into the coefifcent of the variables.

The variables also have to be the same, for instance x can never have a GCF of y.

So remembering this, lets find the GCF of your problem

We see the expoent of the first number is 7. The exponent of the other is 5.

Because we look at the lowest exponent as the GCF, the exponent 5 would be the GCF of the two values.

Then looking at the 8x and 24x, we know that 8x must be the GCF, since 8 equally divides between the 8 and 24, and they both have a x.

So combining the 5 exponent and the 8x:

8x^5

So this is your answer.

There are two equations: 4Y = 3X and 12Y = 9X. What equation describes proportional relationship? What is the constant of propor
AlexFokin [52]

Answer: The equation that describes proportional relationship is y = 0.75x

Constant of proportionality is 0.75

Step-by-step explanation:

4y = 3x

Divide both sides by 4 to get the value of y

y = 3x/4

12y = 9x

Divide both sides by 12 to get the value of y

y = 9x/12 divide the numerator and denominator by a common value of 3

y= 3x/4

y = 0.75x

The equation that describes proportional relationship is y = 0.75x, meaning y is inversely proportional to x, as x increases, y also increases.

Constant of proportionality is 0.75

I hope this helps.

A population of squirrels on an island has a carrying capacity of 350 individuals. If the maximum rate of increase is 1.0 per in
TiliK225 [7]

Answer:

The population growth rate is <u>59</u> squirrels per year.

Step-by-step explanation:

Given:

A population of squirrels on an island has a carrying capacity of 350 individuals. If the maximum rate of increase is 1.0 per individual per year and the population size is 275.

Now, to find the population growth rate.

Carrying capacity (K) = 350.

Maximum rate (r_{max}) = 1.0 per individual per year.

Population size (N) = 275.

Now, to get the population growth rate we put formula:

\frac{dN}{dT}= r_{max}\frac{K-N}{K}N

\frac{dN}{dT}=1.0\times \frac{350-275}{350}\times 275\\\\\frac{dN}{dT}=1.0\times \frac{75}{350}\times 275\\\\\frac{dN}{dT}=1.0\times 0.214\times 275\\\\\frac{dN}{dT}=58.85.

<u><em>So, rounding to nearest whole number of the population growth rate is 59 squirrels per year.</em></u>

Therefore, the population growth rate is 59 squirrels per year.
