The difference of squares is 4m^2 - 20mn + 25n^2

Its a perfect square trinomial.

A perfect square trinomial is the square of a binomial. It follows a pattern when it is factored, so that the first and last terms are perfect squares of monomials and the middle term is twice their product. If the pattern does not fit for a particular trinomial, it is not a perfect square trinomial.

(-2m + 5n)^2

(-2m + 5n)(-2m + 5n)

4m^2-10mn-10mn+25n^2

4m^2 - 20mn + 25n^2

Thus, the difference of squares is 4m^2 - 20mn + 25n^2

Its a perfect square trinomial.

Answer:

(9, 6)

Step-by-step explanation:

the given points are

(3, 2)

(6, 4)

so, can you see, how the sequence continues ?

I see immediately that for every 3 additional units of x we add 2 units of y.

so, yes, the next point in the sequence is

(6 + 3, 4 + 2) = (9, 6).

so, this point (or ordered pair) follows the same ratio or proportional relationship between x and y as the points already in the graph.

in other words, they are on the same line following the same slope ("y coordinate change / x coordinate change" when going from one point on the line to another).

Step-by-step explanation:

so when you want to rationalize the denominator when it's in the form [tex](a-\sqrt{b})[/tex] you multiply by the conjugate which is [tex](a+\sqrt{b})[/tex] which is where the sign is the opposite. This is because it's using the difference of squares to get rid of the square root. Because [tex](a-b)(a+b) = a^2-b^2[/tex] this will remove the square root since it's going to become square and the ab - ab will cancel so there will be no square root

Answer:

40.6°

Step-by-step explanation:

The building and the shadow are perpendicular to each other (or intersect at a 90° angle).

Meaning that this is a triangle problem.

We are making a triangle from the building to the shadow and a diagonal line connecting the ends of both.

We need to find the angle at the top of the building. The opposite side of the angle is 84. The adjacent side is 98.

Opposite / Adjacent = Tan X

So if we go to the calculator:

[tex]tan^{-1} (\frac{84}{98}) = 40.6[/tex]

The answer is 40.6 degrees.

Answer:

16

Step-by-step explanation:

Referring to the diagram, we can use Pythagoras' Theorem to find ZY. (which is the distance from Point Y to WX)

By Pythagoras' Theorem,

[tex]c^{2} =a^{2} +b^{2} \\WY^{2} =WZ^{2} +ZY^{2} \\(16\sqrt{2}) ^{2} =16^{2} +ZY^{2} \\ZY^{2} = (16\sqrt{2}) ^{2} -16^{2} \\ZY^{2} =512-256\\ZY^{2} =256\\ZY=\sqrt{256} \\ZY=16[/tex]

Answer:

A(5 ; 8)

Step-by-step explanation:

y = 5x - 17

y = x + 3

    5x - 17 = x + 3

⇔ 5x - x = 3 + 17

⇔ 4x = 20

⇔ x = 20/4

⇔ x = 5

y = 5 + 3 = 8

So (5 ; 8)

Answer:

We can use the substitution method to solve the system of equations.

Since y = x + 3, we can substitute this expression for y in the first equation:

y = 5x - 17

x + 3 = 5x - 17

Subtracting x from both sides, we get:

3 = 4x - 17

Adding 17 to both sides, we get:

20 = 4x

Dividing both sides by 4, we get:

x = 5

Substituting this value of x into either equation, we get:

y = x + 3 = 5 + 3 = 8

Therefore, the correct ordered pair is (5, 8), which corresponds to the point where the two lines intersect.

The correct answer is (A) (5,8).

Answer:

The given lines are un-related.

Step-by-step explanation:

In the question two functions are given as h(t)=3t-4 and j(t)=5-t.

It is required to find whether these lines are perpendicular, parallel or neither.

Step 1 of 1

Find the slope of two lines by comparing these to the standard form.

y=mx+b

Then, [tex]$m_{1}[/tex]=3

And [tex]$m_{2}[/tex]=-1

Since, both slopes are neither equal nor reciprocal of each other.

Therefore, the lines are un-related.

For random samples of size 100 from a population, the mean of the sample means from all possible samples is less than the population means.

The suggestion of the pattern means will equal the population suggest. the standard deviation of the distribution of the sample means, called the same old blunders of the suggested, is the same as the population trendy deviation divided by means of the rectangular root of the sample length (n).

The general sample suggests components for calculating the pattern mean.

The populace suggest is the mean or average of all values within the given population and is calculated by using the sum of all values within the population denoted with the aid of the summation of X divided by way of the number of values in the population that's denoted with the aid of N.

Answer: 36

Step-by-step explanation:

[tex]\overline{AB} \cong \overline{BC}[/tex] (Triangle ABC is isosceles)

[tex]m\angle CAB=m\angle CBA=30^{\circ}[/tex] (base angles of an isosceles triangle are congruent)

[tex]\angle MCB=90^{\circ}[/tex] (In triangle CMB, angles in a triangle add to 180 degrees)

[tex]\angle ACM=30^{\circ}[/tex] (triangle sum theorem)

[tex]MB=24[/tex] (30-60-90 triangle CMB)

[tex]AB=12[/tex] (sides opposite congruent angles in a triangle are congruent)

[tex]AB=36[/tex] (segment addition postulate)

The value of AB = 36

An isosceles triangle is a triangle with base angles equal with any two sides equal.

Analysis:

∠ACB = 120

ABC is isosceles, so ∠CAB = ∠CBA = x

x + x + 120 = 180 ( sum of angles in Δ ABC)

2x = 60

x = 30

∠AMC = 180 - ∠BMC( angles on a straight line)

           = 180 - 60 = 120

∠ACM = 180 - (30 + 120) = 180 - 150 = 30°

∠MCB = 90°

using sine rule,

12/sin 30 = AM/ sin 30

AM = 12

MB/sin 90 = 12/sin30

MB sin 30 = 12 sin 90

MB = 12/sin 30 = 12/0.5 = 24

AB = MB + AM = 24 + 12 = 36

horizontal asymptote of y = -7

Step-by-step explanation:

The parent function is shown on the coordinate plane. The graph of the parent function has a horizontal asymptote (an imaginary line that the graph approaches, but never touches or intersects) of y = 0.

Since the function of g(x) = e^x - 7 is the graph of the parent function translated 7 units down, the function would have a horizontal asymptote of y = -7.

x = 108°

y = 72°

z = 36°

Step-by-step explanation:

   If all sides are equal in a pentagon, then it is a regular pentagon.

n = the number of sides = 5

Sum of all angles in a pentagon = (n -2) * 180

                                                     = (5 - 2)* 180

                                                     = 3 *180

                                                     = 540°

Sum of each angle of regular pentagon = 540 ÷ 5

                                                                  = 108°

  [tex]\sf \boxed{\bf x= 108^\circ}[/tex]

Linear pair: If the non common arm of adjacent angles form a straight line, then the adjacent angles are called linear pair and they add up to 180°

∠DCB + y = 180 °   {Linear pair}

  108  + y = 180

            y = 180 - 108
