AAS = Angle , angle and one side of 2 congruent triangles

SSS = All 3 sides are measure same of the 2 triangles.

ASA = 2 angles and the side between them are same

HL = A right triangle is congruent if its hypotenuse and one of its legs are congruent with the hypotenuse and one of its other legs.

The dimensions of the triangles' sides and angles determine whether two or more triangles are congruent. A triangle's size is determined by its three sides, and its shape by its three angles. Pairs of corresponding sides and corresponding angles in two triangles are said to be equal if they are congruent. They share a similar size and shape. In triangles, there are numerous congruence conditions. For the two triangles to be congruent, they must be the same size and shape. It should be possible to superimpose the two triangles under examination. A triangle's position or appearance appears to change when we rotate, reflect, and/or translate it. In that situation, we must recognize the six components of a triangle.

Polynomial function of least degree having real coefficient with given leading coefficient 1 and having zeros 3, 4 +i is equal to x³ -11x² +41x -51.

As given,

Standard form of the polynomial function:

f(x) = r(x-a)(x-b)(x -c)

r : leading coefficient

a, b, c are zeros

Polynomial function of least degree having real coefficient with given leading coefficient 1 and having zeros 3, 4 +i is given by

f(x) = 1(x -3) (x -(4+i))(x - (4-i))

⇒ f(x) = (x -3) (x-4 -i)(x -4 +i)

⇒ f(x) = (x-3) [(x-4)² -i²]

⇒f(x) = (x-3)(x² -8x +16+1)

⇒f(x) =(x-3)(x² -8x+17)

⇒f(x) = x³-11x² +41x-51

Therefore, polynomial function of least degree having real coefficient with given leading coefficient 1 and having zeros 3, 4 +i is equal to

x³ -11x² +41x -51.

Answer: Uncle Luke is at 50 years old

Step-by-step explanation: I went through trial and error first with simple t-charts.  In the first one, I simply implemented the piece of info that Luke was 5 times older than the nephew. But then, I realized that Luke would always be 5 years older than his nephew. Here was the info for that t-chart:

[tex]\left \{ {{N=1} \atop {L=5}} \right. \left \{ {{N=2} \atop {L=6}} \right. \left \{ {{N=3} \atop {L=7}} \right.[/tex]

Next, I tried a chart starting with the nephew at 2 years of age, and got an age gap of 8. This helped me realize that I would have to start at 4 years of age in order to have an age gap of 16
[tex]\left \{ {{N=2} \atop {L=10}} \right.[/tex]        |             [tex]\left \{ {{N=4} \atop {L=20}} \right. \left \{ {{N=5} \atop {L=21}} \right.[/tex]  (remember there are 1 increments)

Next, I realized that N=4, L=20 was 40 years ago, so if now the nephew was 44, we can increment 16 to get 50
44+16=50

The height of the barometer on Sunday = 34.8 inches

How is the barometer height on Sunday calculated?

Consider the barometer height for one week,

The average height of a barometer during one week = 30.84 inches

The total height of a barometer during one week = 30.84 * 7

                                                                                  = 215.88

Consider the barometer height for 6 weekdays,

The average height of a barometer for 6 weekdays of the same week= 30.18 inches

The total height of a barometer for 6 weekdays = 30.18 *6

                                                                                =181.08

The barometer height  on Sunday = One week height- 6 days height

                                                         =215.88 - 181.08

                                                         =34.8  inches

The given vertices are A(1,4), B(3,-2), and C(4,2).

The reflection over the x-axis is expressed as

This means we have to multiple each y-coordinate with -1. Let's do it!

Using the equation for the distance between two points, the distance between Ross and Rachel is given by the following option:

D. 19 miles.

Suppose that we have two points with coordinates [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The shortest distance between them is given by the equation presented as follows:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

This formula is derived from the Pythagorean Theorem, as the points form a right triangle in the xy-plane, and the hypotenuse represents the distance between them.

Their coordinates in this problem are as follows:

Each unit on the plane represents a mile, hence their distance is given as follows:

[tex]D = \sqrt{(8 - (-4))^2+(-4 - 11)^2}[/tex]

D = 19.2 miles.

The triangle have shorter sides of 12.9 and 14.9 cm, respectively

From the question, the given parameters are:

Also, from the question, we have:

Two shaded sides of the triangle differ by 2

In this case, the shaded sides of the triangle are

Opposite and Adjacent

This can also be interpreted as

Base and Height

So, we have

Base - Height = 2

The area is calculated as

Area = 0.5 * Base * Height

So, we have

0.5 * Base * Height = 96

This gives

0.5 * (Height + 2) * Height = 96

Divide by 0.5

(h + 2) * h = 192

Using a graphing calculator, we have

h = 12.9

Substitute h = 12.9 in Base - Height = 2

Base - 12.9 = 2

Evaluate

Base = 14.9

Recall that the Opposite and Adjacent are the shorter sides of a right triangle

Hence, the shorter sides are 12.9 and 14.9 cm

Hope this helps!

Answer:

u = 24

Step-by-step explanation:

-7/8u = -21

Solve for u

Multiply each side by -8/7

-8/7 *-7/8u = -21 *-8/7

u =3*8

u = 24

Answer:

u = 1/24

Write the equation:

–7/8u = –21

Get rid of fraction:

–7/2^3 • u = –21

–7 = ( – (8u) ) 21

Solve:

–7 = –8u + 21

–7 + 8u = –8u + 8u + 21

–7 + 8u = 21

–7 + 7 + 8u = 21 + 7

8u = 21 + 7

8u = 28

u = 1/24

The inequality to determine the number of packages Renna could remove from the elevator to meet the mass requirement is 620 - 37.4g = 450.

An inequality is simply used to show the relationship between the expressions that are not equal.

The mass limit is given as 450 grams. Renna has a package that has a weight of 620g.

Each package has 37.4g.

Let the number of packages to remove be p.

The expression will be:

= 620 - (37.4 × p) = 450

620 - 37.4g = 450.

Firts get the equation

Second, write the equation in form of Ax +

Answer:

  3.97%

Step-by-step explanation:

You want to know the annual interest rate, compounded daily, that will result in $43,000 growing to $75,000 in 14 years.

The formula for the account value is ...

  A = P(1 +r/n)^(nt)

where P is the principal invested at annual rate r compounded n times per year for t years.

Filling in the given values, we can solve for r.

  75000 = 43000(1 +r/365)^(365·14)

  75/43 = (1 +r/365)^5110 . . . . . divide by 43000 and reduce the fraction

Taking the 1/5110 power gives ...

  (75/43)^(1/5110) = 1 +r/365 ≈ 1.00010886855

  r/365 = 0.0010886855 . . . . subtract 1

  r = 0.001086855·365 . . . . . multiply by 365

  r ≈ 0.039737 = 3.9737%

The required interest rate is about 3.97%.

The visitor attended no special exhibits and so paid a total of $10 just to get in.

An equation to represent the cost of admission could look like this:

f(x) is the total cost.

x is the number of special exhibits attended.

f(x) = 2x + 10

If I see no special exhibits on my visit,

The summation is the adding two quantities thus the reasonable estimate of the total length of the trench is 1 1/2 meters so option (C) is correct.

A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities.

There could be only two terms, but there could be one hundred, a thousand, or a million.

Here are always an integer number of terms in a summation.

As per the given,

Length of the trench on the first day = 18/20 meters

Length of the trench on the second day = 9/20

Total length of the trench = 18/20 + 9/20

Take LCM as 20

⇒ (18 + 9)/20 = 27/20

⇒ 1.35 which is closest among the given option by 1 1/2 meters.

Hence "The summation is the adding two quantities thus the reasonable estimate of the total length of the trench is 1 1/2 meters".

The slope for lot size is not different from 0.

If we consider a confidence level (the probability for which we can be confident that the null hypothesis is true) to be 95% (Probability = 0.95) then the level for which we are not confident that the null hypothesis is true will be (100 - 95)% = 5% (Probability = 0.05)

Thus, for this coefficient the P value is 0.5782.

As the p-value is more than the Probability for which we are not confident (0.05), so in this regard we can state then there is no such significance difference seen in this regard. Thus, we accept the null hypothesis here. This means that we can take the coefficient to be 0.
