Answer:

  4 pairs

Step-by-step explanation:

You want the number of pairs of integers (m, n) such that m > n and m² -n² = 96.

The difference of squares is factored as ...

  m² -n² = (m -n)(m +n)

In order for the difference to be 96, these factors must be factors of 96.

The prime factorization of 96 is ...

  96 = 2^5 · 3

The number of divisors of 96 is the product of the exponents of these factors, each increased by 1:

  (5+1)(1+1) = 12

That is, there are 12/2 = 6 factor pairs ab such that a<b. They are ...

   96 = 1·96 = 2·48 = 3·32 = 4·24 = 6·16 = 8·12

The values of m and n relate to the values of 'a' and 'b' by ...

  m = (a+b)/2

  n = (b-a)/2

In order for m and n to be integers, the values of 'a' and 'b' must both have the same parity. That is, they must both be even, or both be odd. This eliminates the factor pairs 1·96 and 3·32, leaving 4 (a, b) pairs, hence 4 (m, n) pairs. Possible ordered pairs are ...

  (m, n) ∈ {(25, 23), (14, 10), (11, 5), (10, 2)} . . . . . 4 pairs

Answer: -1.73 ft

Step-by-step explanation:

(-2.54 - 3.16 - 2.82 + 1.6) / 4 = -1.73

The equation of the function in slope-intercept form with slope of 2 is y = 2x+19.

According to the question,

We have the following information:

Slope = 2 (Note that slope of a line is denoted by m.)

Points through which function is passing = (-8,3)

So, we have x' = -8 and y' = 3.

We know that the following equation is used to find the equation of the function or line:

(y-y') = m(x-x')

y-3 = 2{x-(-8)}

y-3 = 2(x+8)

y-3 = 2x+16

y = 2x+16+3

y = 2x+19

Hence, the equation of the function in slope-intercept form with slope of 2 is y = 2x+19.

Exterior alternate angles are congruent based on the alternate exterior angles theorem. Conversely, it can also be stated that if two angles, which are exterior alternate angles, are congruent to each other, therefore the lines they lie on that is crossed by a transversal are proven to be parallel to each other based on the converse of alternate exterior angles theorem.

Given that angles 11 and 13 are congruent angles, the diagram also shows that they are alternate exterior angles. They lie on each lines, c and d, that are crossed by transversal a.

The equation of the graph is given by y = ( x + 2 )² + 3

Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.

Identify the even and odd multiplicities of the polynomial functions' zeros.

Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.

The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities

Given data ,

Let the equation be represented as A

Now , the value of A is

y = ( x + 2 )² + 3

The area of the smaller triangle is 18 squared units which is determined by the property of similar triangles.

The area of the larger triangle is 36.

The two triangles are similar which is given in the question

We know that the corresponding sides of similar triangles are being in the same ratio.

As per the property of similar triangles,

A₁ : S₁ = A₂ : S₂

Here A₁ is area of the larger triangle,  A₂ is area of the smaller triangle

S₁ is side of the larger triangle, and S₂ is side of the smaller triangle,

⇒ A₁ / S₁ = A₂ / S₂

⇒ 36 / 12 = A₂ / 6

⇒ 3 = A₂ / 6

⇒ A₂ = 18

Therefore, the area of the smaller triangle is 18 squared units.

The product of two consecutive non-negative integers is 240 and the integers are 15,16.

What are consecutive integers?

Let the numbers be x, x+1

Product is x(x+1)=240

x² + x = 240

x² + x − 240 = 0

x² + 16x − 15x − 240 = 0

x(x+16) − 15(x+16) = 0

(x+16)(x−15)=0

The order of T is 82.

Let n and e be the order and number of edges of T respectively.

Also, let a, b, c and d be the number of vertices of degree 2, 3, 4 and 5 respectively.

Then, 50+a+b+c+d = n

And by the Handshake Lemma,  the sum of the degrees of all the vertices of T is twice the number of edges, so we have

50+2a+3b+4c+5d = 2e

Since a=b=c=d then we have the following two equations,

50+4a = n

50+14a = 2e

But, T is a tree so e=n=1, then the two equations become,

50+4a = n ...............(1)

50+14a = 2(n-1) .............(2)

Solving for a in (1) we get,

a = [tex]\frac{n-50}{4}[/tex]

Plugging a into (2) we get,

50+14([tex]\frac{n-50}{4}[/tex]) = 2(n-1)

50+3.5n-175 = 2n-2

3.5n-2n = 175-50-2

1.5n = 123

n = [tex]\frac{123}{1.5}[/tex] = 82

Answer:

28.3

Step-by-step explanation:

To solve this problem, we must follow PEMDAS, which must be used in solving all mathematical equations and expressions.

PEMDAS is the order you solve the equation/expression in. It is an acronym for:

P: Parenthesis

E: Exponents

M: Multiplication

D: Division

A: Addition

S: Subtraction

Keep in mind that multiplication and division are too be done left and right. You do not do multiplication first and division last, read left to right. Same goes with addition and subtraction.

This is the less confusing notation of PEMDAS.

P: Parenthesis

E: Exponents

M: Multiplication D: Division

A: Addition S: Subtraction

Now, lets solve the problem.

92.3 - (3.2 ÷ 0.4) × 2³

What do we do first? Well since parenthesis is first according to PEMDAS, we must solve the division in side of the parenthesis first.

3.2/0.4 = 8

Now we have:

92.3 - (8) × 2³

Remove the parenthesis as there is only one term inside and therefore not needed.

92.3 - 8 × 2³

What do we do next?

We have:

Subtraction: 92.3 - 8

Multiplication: -8 × 2³

Exponent: 2³

Because PEMDAS states exponents is to be solved in front of multiplication/division and addition/subtraction, we must do that.

What is an exponent?

2³

2 is the base, 3 is the exponent.

2³

Means multiplying 2 by itself 3 times:

2 × 2 × 2

8

Now we have:

92.3 - 8 × 8

Because PEMDAS states solving multiplication/division is prioritized over addition/ subtraction, we must solve 8 × 8

8 × 8 = 64

Now we have: 92.3 - 64

Solve.

The force of attraction is 2.78 Newton when m = 2 kilograms and d = 15 meters.

According to the question,

We have the following information:

The force of attraction, F of a body varies directly as its mass (m) and inversely as the square of the distance (d) from the body. And when m=8kg and d=5meters then F=100 Newtons.

Now, let's take the constant for this case to be k.

We have the following expression:

F = km/[tex]d^{2}[/tex]

Putting the values in this expression to find the value of k:

100 = 8k/(5*5)

Using the cross multiplication method:

2500 = 8k

k = 2500/8

k = 312.5

Now, we have the following value of F:

F = 312.5*2/15*15

F = 625/225

F = 2.78 Newton

Hence, the force of attraction is 2.78 Newton when m = 2 kilograms and d = 15 meters.

Hey, so because you didn't include the image this is impossible to get the number values.  But, essentially you'd solve it something like this.

Remember, the Y axis goes up, and its located when you are at X = 0.  

The y intercept is the value of Y, when is 0.  

The slope of a line is referred to as "rise/run"

Basically, you take any given spot.  For example, from x = 0 to x = 2.  The run is 2, because thats how much x value the line covers.  So, in that "run" how much do you go up or go down?  Lets say in those 2 x's that you travelled, how much did the height change?  If you changed by going up 4 units, it would be (rise/run) 4/2 = 2.  The slope would be 2.  That means that for every time x increases by 1, Y goes up 2.

Step-by-step explanation:

By the Triangle Inequality Theorem:

30 + x > 30, so x > 0

x + 30 > 30, so x > 0
