The inverse of the statement is M be the point on PQ since PM is congruent to QM than M is midpoint on the PQ.

Inverse of the statement means that explain the condition in reverse way or vice versa.

Since, M is the midpoint of PQ, then PM is congruent to QM.
Proving in reverse way, let m be the point between P and Q the distance M from P is equal to the distance from M to Q. Which implies that M lies as the mid of the P and Q.

Thus, the inverse of the statement is M be the point on PQ since PM is congruent to QM than M is midpoint on the PQ.

You have the correct answer. Apply a 180 degree rotation around the point (0,2)

Reason:

We'll connect corners between figures A and B.

Draw a line from the upper right corner of figure A to the lower left corner of figure B. This line is in red (see diagram below).

Draw another line from the lower right corner to the upper left corner. This line is in blue.

The red and blue lines intersect at the center of rotation (0,2)

The line segments constructed consist of endpoints of "before" and "after". For instance, the upper right corner in figure A rotates to the lower left corner of figure B. This happens because of the 180 degree rotation.

Note: You can do this rotation either clockwise or counterclockwise, and you would get the same result.

Answer:

[tex]\sf \dfrac{x+2}{x}[/tex]

Step-by-step explanation:

Simplifying the expression:

 1. Factorize each expression.

     x² + 8x + 15

   Sum = 8

  Product = 15

  Factors = 3 , 5  {When we add 3 & 5 we get 8 and when we multiply 3*5, we get 15}

  x² + 8x + 15 = x² + 3x + 5x + 15

                     = x(x + 3) + 5(x + 3)

                     = (x + 3)(x + 5)

x² - 2x - 15

 Sum = -2

Product = -15

Factors = 3 , (-5)  {When we add 3 + (-5) =2 and when we multiply, 3*(-5) = -15}

x² - 2x - 15 = x²  + 3x - 5x - 15

                 =x(x + 3) -5(x + 3)

                 = (x + 3)(x - 5)

x² + 5x = x( x + 5)

x² - 3x - 10

Sum = -3

Product = -10

Factors = 2 , (-5)  {When we add 2 +(-5) = -3 and when we multiply 2 *(-5) = -10}

x² - 3x - 10 = x² + 2x - 5x - 10

                 =x(x + 2) - 5(x + 2)

                 = (x + 2)(x - 5)

2. Use KCF method and simplify.

  K - keep the first fraction

  C - change division to multiplication

 F -  Flip the second fraction.

[tex]\sf \dfrac{x^2 + 8x + 15}{x^2 - 2x - 15} \ \div \ \dfrac{x^2 + 5x}{x^2 - 3x - 10}=\dfrac{x^2 + 8x + 15}{x^2-2x - 12}*\dfrac{x^2 - 3x - 10}{x^2 + 5x}[/tex]

The measure of ∠STR in the isosceles triangle is 24°

What is an isosceles triangle?

A triangle having two sides of equal length is termed as an isosceles triangle. The base angles of an isosceles triangle are also equal in measure. The fact that the perpendicular bisector of the base and the angle bisector of the vertex angle are the same is another crucial characteristic of an isosceles triangle. We refer this as Isosceles Triangle Theorem.

What is the value of angle STR?

It is given that in isosceles triangle SQT,

∠STQ = 48°

Since, the line TR is the angle bisector of angle STQ, we have,

∠STR = ∠RTQ

And, ∠STR + ∠RTQ = ∠STQ

Let ∠STR be x, the, we get,

x + x = ∠STQ

⇒ 2x = 48°

⇒ x = 24°

x = 45°

N) x² + x² = (7√2)²

x = 7

V) Tan(60°) = 7 / x

x = 7√3/3

K) x² + x² = (9)²

Answer:

s(t) = -4.9t² + 39.2t

Step-by-step explanation:

Given the projectile motion of an object can be modeled using s(t) = gt2 + v0t + s0, where g is the acceleration due to gravity, t is the time in seconds since launch, s(t) is the height after t seconds, v0 is the initial velocity, and s0 is the initial height. The acceleration due to gravity is –4.9 m/s²

Given

g = -4.9m/s²

v0 = 39.2m/s

s0 = 0m (the initial height)

On substituting into the formula;

s(t) = gt² + v0t + s0

s(t) = -4.9t² + 39.2t + 0

s(t) = -4.9t² + 39.2t

This gives the equation that models the height

The system of linear inequalities to represent this situation. is given as-

9p <= 480

a >= 8s

p = a + s

Expressions with linear inequalities compare any two values using inequality symbols like "<," ">," "<=," or ">=." These values could be either numerical, algebraic, or both.

If the linear inequality is larger than or less than but not equal to, a dashed line appears on the graph. On the other hand, a solid line always appears in linear equations. Linear equations lack shaded sections, whereas linear inequalities do.

According to the question,

The buses can carry a maximum of 480 people.

These people include adults as well as students.

Let 'p' represents the total number of people in the bus.

Let 'a' represents the number of adults in the bus.

Let 's' represents the number of students in the bus.

Thus,

p = a + s.

As, there must be a minimum of one adult for every 8 students.

a >= 8s

The equation of the line containing (- 4,5) and perpendicular to the line 5x - 3y = 4 is y = -3 / 5 x + 13 / 5

The equation of a line can be represented as follows:

y = mx + b

where

Therefore, the equation passes through (-4, 5) and perpendicular to 5x - 3y = 4

Hence,

perpendicular lines follows the rule below:

m₁m₂ = -1

Hence,

5x - 3y = 4

5x - 4 = 3y

y = 5/ 3 x - 4 / 3

m₁ = 5 / 3

5/3 m₂ = -1

m₂ = - 3 / 5

Hence,

using (-4, 5)

5 = - 3 / 5 (-4) + b

5 = 12 / 5 + b

b = 5 - 12 / 5 = 25 - 12 /5 = 13 / 5

Answer:

  3x +5y = 13

Step-by-step explanation:

The equation of a perpendicular line through a given point can be obtained by swapping the x- and y-coefficients of the original line's equation, and negating one of them. The constant in the equation needs to be chosen so the equation will be true at the given point.

Swapping the coefficients of the given equation, we have ...

  3x -5y = c . . . . . for some constant c

Negating the y-coefficient gives a perpendicular line:

  3x +5y = c

We want the equation to be true for (x, y) = (-4, 5), so the constant needs to be ...

  3x +5y = 3(-4) +5(5) = -12 +25 = 13

The equation of the perpendicular line is ...

  3x +5y = 13

Additional comment

This process works for equations given in any form. If you start with point-slope form or slope-intercept form, some manipulation of the result may be required to get to the form you want. Standard-form or general-form equations are the easiest to apply this method to.

Note that equations in standard form want to have a positive leading coefficient. That is why we chose to change the sign of the y-coefficient, rather than the x-coefficient.

m<BPR = 65

angles:

<APQ, x, and <BPR form a straight line and so their sum is equal to 180

Answer:

None of these

Step-by-step explanation:

None of this expressions are equivalent. But if the original polynomial is 9x^2-4, then answer would be (3x+2)(3x-2).

Using formula (a+b)(a-b)=a^2-b^2 , it follows:

(3x+2)(3x-2)=(3x)^2-2^2=9x^2-4

Answer: The correct answer is choice A.

Step-by-step explanation:

This is because the triangles have the same angles, but are scaled differently.  Thus because of the scale, there can be no correlation between the sides. Because the triangles share point E you can see that both triangles share the same angle but also notice how lines CD and AB are parallel. This makes all angles identical proving the triangles are the same but different sizes. Concluding that choice A is correct.

The equation of Daredevil Danny's jump in vertex form is y = -0.32(x - 25)^2 + 32

The graph of Daredevil Danny's jump is added as an attachment

A quadratic function is represented as:

y = a(x - h)^2 + k

From the graph, we have:

So, we have:

y = a(x - 25)^2 + 32

Substitute the value of the x-intercept

0 = a(15 - 25)^2 + 32

Subtract 32 from both sides

a(15 - 25)^2 = -32

Solve for a

a = -0.32

Substitute a = -0.32 in y = a(x - 25)^2 + 32

y = -0.32(x - 25)^2 + 32

Expand the exponent

y = -0.32(x^2 -50x + 625) + 32

Expand the bracket

y = -0.32x^2 + 16x - 200 + 32

This gives

y = -0.32x^2 + 16x - 168

Hence, the values of the coefficients a, b and c are -0.32, 16 and -168
