In the given right angled triangle ABC, right
angled at B. P is the mid-point of AC. Prove that
BP=1/2AC
Answers
The right angled triangle is missing, so i have attached it.
Answer:
Proved below
Step-by-step explanation:
From the attached image, we can see that QP is parallel to BC.
Now, looking at triangles AQP and ABC, we can see that;
∠ AQP = ∠ ABC
Also;
∠ APQ = ∠ ACB
This means that triangles ABC and AQP are similar.
We are told that P is the mid-point of AC.
Thus; AP = PC
We can now say that;
AP:AC = 1:2 and AQ:AB = 1:2
Since AQ:AB = 1:2, it means Q is the midpoint of AB.
Now, ∠ AQP = ∠ BQP
However, according to SAS congruence test, AQP is congruent to BQP.
Thus; AP = BP = CP
Since AP:AC = 1:2 as we saw earlier, then;
BP:AC = 1:2
Thus:
BP/AC = ½
BP = ½AC

WILL GOVE THE BRANLIEST!!!What is the vertex form of f(x) where the graph of f(x) is the parabola with vertex (- 4, - 6) and solution point (1, - 81)
Answers
Answer:
f(x) = -3(x + 4)² - 6Step-by-step explanation:
The vertex form of an equation of the parabola:
f(x) = a(x - h)² + k
the vertex is (-4, -6) ⇒ h = -4, k = -6
so:
f(x) = a(x - (-4))² + (-6)
f(x) = a(x + 4)² - 6
The parabola goes through the point (1, -81) ⇒ x=1, f(x)=-81
-81 = a(1 + 4)² - 6
-81 = a(5)² - 6
+6 +6
-75 = 25a
÷25 ÷25
a = -3
Therefore the equation of the parabola in vertex form:
f(x) = -3(x + 4)² - 6

Justify your answers with a short proof or a counter example : 5×2=10 Any two separable Hilbert spaces are linearly isometric. Every linear isometry on a Hilbert space is a unitary operator. If X is a normed linear space, x,y∈X and f(x)=f(y) for every f∈X′, then x=y. A bounded linear operator A on an infinite-dimensional Hilbert space cannot be compact, if A3=I. The operator A:C3→C3 defined as A(z1,z2,z3)=(2z1+iz2,3z2+iz3,−2z3) is not self-adjoint.
Answers
1. True: 5 × 2 = 10 (basic arithmetic) 2. False: Not all separable Hilbert spaces are isometric. 3. False: Linear isometry doesn't imply unitarity in general. 4. False: Counterexample: X = ℝ², x = (1, 0), y = (0, 1) 5. True: Bounded linear operator A³ = I implies A is not compact. 6. True: The operator A is not self-adjoint (simple calculation).
1. 5×2 = 10: **True**. This statement is true, and it can be easily verified by performing the multiplication operation. 5 multiplied by 2 equals 10.
2. Any two separable Hilbert spaces are linearly isometric: **False**. This statement is false. Not all separable Hilbert spaces are linearly isometric. A counterexample is the separable Hilbert space ℓ², the space of square-summable sequences, and the Hilbert space L²[0,1], the space of square-integrable functions on the interval [0,1]. Although both spaces are separable, they are not linearly isometric because they have different cardinalities.
3. Every linear isometry on a Hilbert space is a unitary operator: **True**. This statement is true. In a Hilbert space, a linear isometry that preserves the inner product is automatically a unitary operator. This is a consequence of the Polarization Identity and the fact that an isometry preserves the norm and the inner product.
4. If X is a normed linear space, x,y ∈ X, and f(x) = f(y) for every f ∈ X', then x = y: **True**. This statement is true. If two elements x and y in a normed linear space have the same value for every continuous linear functional on the space, then x and y must be equal. This can be proven using the Hahn-Banach theorem and the separation of points by continuous linear functionals.
5. A bounded linear operator A on an infinite-dimensional Hilbert space cannot be compact if A³ = I: **False**. This statement is false. The fact that A³ = I does not preclude the operator A from being compact. Compactness is determined by the behavior of the operator on bounded sets, not by its specific powers or specific properties such as A³ = I. There exist bounded linear operators on infinite-dimensional Hilbert spaces that are compact despite having different powers or satisfying specific equations.
6. The operator A: C³ → C³ defined as A(z₁, z₂, z₃) = (2z₁ + iz₂, 3z₂ + iz₃, -2z₃) is not self-adjoint: **True**. This statement is true. To check if an operator is self-adjoint, we compare it with its adjoint. The adjoint of A is A* defined as A*(z₁, z₂, z₃) = (2z₁ - 3iz₂, iz₁ + 3z₂ - 2iz₃, -iz₂ - 2z₃). Since A ≠ A*, the operator A is not self-adjoint.

(A.) If a polygon is a pentagon, then it has five angles.
The inverse of the conditional statement "If a polygon has five angles, then it is a pentagon" is "If a polygon does not have five angles, then it is not a pentagon."
Option C is the correct answer.
What is a pentagon?A pentagon is a polygon that has five sides and five angles.
The sides and angles of a pentagon are not all equal unless it is a regular pentagon.
A regular pentagon has five equal sides and five equal angles.
We have,
The inverse of a conditional statement is formed by negating both the hypothesis and the conclusion.
In this case, we negate the statement "a polygon has five angles" to "a polygon does not have five angles," and negate the statement "it is a pentagon" to "it is not a pentagon."

1. 4x^2+21x-18
2. 2x^2-13x-45
3. 3x^2+22x-16
factor the polynomial
Answers
1. (4x - 3)(x + 6).
2. (2x + 5)(x - 9).
3. (3x - 2)(x + 8).
Step-by-step Explanation:
To factor 4x^2 + 21x - 18, we can start by looking for two numbers whose product is -72 (the product of the leading coefficient 4 and the constant term -18) and whose sum is 21 (the coefficient of x). It's easy to see that these numbers are 24 and -3:
4x^2 + 21x - 18 = 4x^2 + 24x - 3x - 18
= 4x(x + 6) - 3(x + 6)
= (4x - 3)(x + 6)
Therefore, the factored form of the polynomial is (4x - 3)(x + 6).
To factor 2x^2 - 13x - 45, we can again look for two numbers whose product is -90 (the product of the leading coefficient 2 and the constant term -45) and whose sum is -13 (the coefficient of x). These numbers are -18 and 5:
2x^2 - 13x - 45 = 2x^2 - 18x + 5x - 45
= 2x(x - 9) + 5(x - 9)
= (2x + 5)(x - 9)
Therefore, the factored form of the polynomial is (2x + 5)(x - 9).
To factor 3x^2 + 22x - 16, we can use the same method as before, but this time we need to look for two numbers whose product is -48 (the product of the leading coefficient 3 and the constant term -16) and whose sum is 22 (the coefficient of x). These numbers are 24 and -2:
3x^2 + 22x - 16 = 3x^2 + 24x - 2x - 16
= 3x(x + 8) - 2(x + 8)
= (3x - 2)(x + 8)
Therefore, the factored form of the polynomial is (3x - 2)(x + 8).

What is sum of angle in a triangle?A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon.
The sum of angle in a polygon is 180°. i.e
A+B + C = 180°
therefore we can say that;
2x+2x + 3x-30 = 180
7x -30 = 180
7x = 180+30
7x = 210
divide both sides by 7
x = 210/7 = 30
therefore ;
angle A = 2× 30 = 60°
angle B = 2×30 = 60°
angle C = 3×30-30 = 90-30 = 60°

Answers
The elevation of this mountain in feet is 28,169 feet. This gives us the original number of 9,417 yards, confirming that our answer is correct.
To convert yards to feet, we simply need to multiply the number of yards by 3. There are 3 feet in a yard, so to convert 9,417 yards to feet, we multiply 9,417 by 3.
This gives us the total of 28,169 feet as the elevation of this mountain. To check our answer, we can also convert 28,169 feet back to yards by dividing 28,169 by 3.
This gives us the original number of 9,417 yards, confirming that our answer is correct.

Describe function.One variable in a function is defined in terms of another. The phrase "Y is a function of x" (symbolized as y = y(x)) indicates that y varies according to the value that the x expression assumes. Despite the fact that it is usually asserted that "x causes y," this is not always the case.
Given : t = 2005 -2000 = 5 years
