D. Proportional Medians Theorem

Answers

C. Proportional Altitudes theorem :)

The Proportional Medians Theorem states:If two triangles are similar, then the ratio of the lengths of two corresponding medians is the same as the ratio of the lengths of two corresponding sides.

A median of a triangle is a line segment joining a vertex to the midpoint of the opposing side, bisecting it.

It is given the two triangles are similar.FG and TU are the medians of the triangle .

By Proportional Medians Theorem ratio of the lengths of two corresponding medians is the same as the ratio of the lengths of two corresponding sides.

So [tex] \frac{FG}{TU} =\frac{EF}{ST} [/tex]

Option D. Proportional Medians Theorem is the right answer.

Sketch the following to help answer the question. Kite QRST has a short diagonal of QS and a long diagonal of RT. The diagonals intersect at point P. Side QR = 5 m and diagonal QS = 6 m. Find the length of segment RP.
3 m
4 m
5 m
6 m

Answers

The length of RP is 4 m.

Since a kite is symmetric about one of its diagonals, then the other diagonal bisects that one. Additionally, the diagonals are perpendicular to each other. This forms two right triangles inside of the kite.

The bottom leg of the right triangle will be 3 (half of the diagonal) and the hypotenuse will be 5. We will use the Pythagorean theorem to answer this:

3²+b²=5²
9+b²=25

Subtract 9 from both sides:
9+b²-9=25-9
b²=16

Take the square root of both sides:
√(b²) = √16
b=4

Answer:

Given: Kite QRST has a short diagonal of QS and a long diagonal of RT. The diagonals intersect at point P. Side QR = 5m and diagonal QS = 6m.

Since, diagonals of kite bisect each other, thus QP=6m

Now, in ΔPQR, we have

(QR)²= (RP)²+(QP)²

(5)²= (3)²+(RP) ²

25=9+(RP)²

25-9= (RP)²16= (RP)²

RP= 4m

Therefore, the length of segment RP is 4m.

Write the equation in slope-intercept form of the line that has a slope of -5 and a y-intercept of 2.

Answers

Hi!

Slope intercept form is in the form y=mx+b
m is the slope, and that is given so we can plug that into the equation

y = -5x + b

We are also given the y-intercept (0,2) and we can plug that into the equation as well, to find b

2 = 5(0) + b
2 = b

So now that we know both m and b, plug only those two into the equation.
y = -5x + 2

That is your equation

What are the zeros of the quadratic function f(x) = 2x2 + 8x – 3? x = –2 – and x = –2 + x = –2 – and x = –2 + x = 2 – and x = 2 + x = 2 – and x = 2 +

Answers

The given quadratic function is:

[tex]f(x)=2 x^{2} +8x-3[/tex]

The zeros of the quadratic functions also known as its roots can be found using the quadratic formula.

According to the quadratic formula:

[tex]x= \frac{-b+- \sqrt{ b^{2}-4ac } }{2a} [/tex]
here,
b = coefficient of x-term
a = coefficient of x²-term
c = costant term

For given function:
a = 2
b = 8
c = - 3

Using these values in the formula, we get:

[tex]x= \frac{-8+- \sqrt{64-4(2)(-3)} }{2(2)} \\ \\ x= \frac{-8+- \sqrt{88} }{4} \\ \\ x= \frac{-8+-2 \sqrt{22}}{4} \\ \\ x= \frac{-4+- \sqrt{22} }{2} \\ \\ x= \frac{-4+ \sqrt{22} }{2}, x= \frac{-4- \sqrt{22} }{2} [/tex]

Thus, these values of x are the zeros of the given quadratic function f(x)=2x²+8x-3

Write three to five sentences explaining which levels of production provide Alonzo’s Cycling with the maximum profit.

Answers

The optimal level of production for Alonzo's Cycling is at the point where the profit reaches its peak before starting to decline with further increases in production. This is the level of production that Alonzo's Cycling should aim for to achieve the marginal profit.

To determine which levels of production provide Alonzo's Cycling with the maximum profit, one must consider both the fixed costs and the variable costs associated with production.

The profit for each level of production is calculated by subtracting the total costs (fixed costs plus variable costs) from the total revenue generated by sales. The level of production at which profit is maximized is where the difference between total revenue and total costs is the greatest.

This can be found by analyzing the marginal cost and marginal revenue of production. When marginal revenue equals marginal cost, and if the additional production leads to a decrease in profit, that is the point of maximum profit.

Beyond this point, producing more units would decrease the total profit due to the law of diminishing returns, where the cost of producing additional units exceeds the revenue they generate.

Therefore, the optimal level of production for Alonzo's Cycling is at the point where the profit reaches its peak before starting to decline with further increases in production. This is the level of production that Alonzo's Cycling should aim for to achieve the maximum profit.

Then, the dot ran from −34 to −66. What distance did it cover? If this run took the dot 5 minutes, what was its average speed?

Answers

The distance between -66 and -34 is 32 units. To find the speed in 5 minutes, you will divide the distance of 32 units by the time it took to travel that distance (5 minutes). You can write it as a rate 32 units/5 mins. The speed is 6.4 units per minutes when you divide it out.

Final answer:

The dot covered a distance of 32 units when it ran from -34 to -66. Assuming the distance is measured in meters, and the dot took 5 minutes (300 seconds) to cover this distance, the average speed would be 0.1067 m/s.

Explanation:

To determine the distance the dot covered when it ran from -34 to -66, we need to calculate the absolute value of the difference between the two points. The formula for distance in this case is |final position - initial position|, so the distance covered = |-66 - (-34)| = |-66 + 34| = | -32 | = 32 units.

Now, to determine the average speed of the dot, we divide the total distance traveled by the time it took to cover that distance. Given that it took the dot 5 minutes to cover the distance, we convert minutes to seconds because speed is typically measured in meters per second (m/s) in physics. There are 60 seconds in a minute, so 5 minutes is 300 seconds. Therefore, the average speed is distance/time = 32 units / 300 seconds.

The exact units of measurement for distance have not been specified in the question, but assuming the distance is in meters (m), the average speed would be calculated as 32 m / 300 s = 0.1067 m/s.

4.9x10^11.
One can solve this question by converting 1,400,000 into scientific notation. The equation then becomes --> (1.4x10^6)(3.5x10^5). Then, one can multiply 1.4 by 3.5 and use exponent laws to get x10^11.
1.4x3.5 = 4.9
(10^6)(10^5)=10^11
Therefore, the answer will be 4.9x10^11.

The answer is [tex]$ 4.9 \times 10^{11} $[/tex].

To solve the given mathematical problem, we will multiply the two numbers and then express the result in scientific notation.

First, let's multiply 1,400,000 by 3.5x10^5 without converting them to scientific notation:

[tex]\[ 1,400,000 \times 3.5 \times 10^5 \][/tex]

[tex]\[ = 1400000 \times 3.5 \times 10^5 \][/tex]

[tex]\[ = 4900000 \times 10^5 \][/tex]

Now, we have the product 4900000. To express this in scientific notation, we must write it as a number between 1 and 10 multiplied by a power of 10. The number 4900000 can be written as 4.9 followed by 11 zeros, which in scientific notation is [tex]$ 4.9 \times 10^{11} $[/tex].

Therefore, the final answer, expressed in scientific notation, is:

[tex]\[ \boxed{4.9 \times 10^{11}} \][/tex]

Answers

Since RT bisects QS, we have QT congruent to ST. Bisect means it cuts QS in half. The we have RT congruent to RT since it is the same. By SSS, we have triangle QRT congruent to triangle SRT since QT is congruent to ST, RT is congruent to RT, and QR is congruent to SR. Each side is congruent to its respective side in the other triangle and that is SSS (side, side, side).

The answer is Definition of a segment bisector; SSS.
Explanation:

Since RT bisects QS, we have QT congruent to ST.
By SSS, we have triangle QRT congruent to triangle SRT
so, since QT is congruent to ST, RT is congruent to RT, and QR is congruent to SR.
All these sides are congruent to each other that gives the proof of "SSS(SIDE, SIDE, SIDE)"

Where preset population = P= 775

Rate of increase = r = 51% = 0.51

t= number of years

A= Future value.

Plug these values into above formula:

[tex]A=775(1+0.51)^t[/tex]

[tex]A=775(1.51)^t[/tex]

Hence required exponential function is [tex]A=775(1.51)^t[/tex]

Answer(b):

plug t=10 years

[tex]A=775(1.51)^t=775(1.51)^{10}=775(61.6267795034)=47760.7541151[/tex]

which is approx 47761.

Answer(c):

we know that
the equation of the circle with center (0, 0) is ---------> x²+y²=r²

Step 1

r=√29
the equation of the circle is
x²+y²=29

the answer is x²+y²=29

1. You have that:

r²=(x-h)²+(y-k)²

2. The center of this circle is (0,0), then:
