Which quadrilaterals have perpendicular diagonals. A) Rhombus, Rectangle and Kite B) Rectangle, Square and Isosceles Trapezoid C) Square, Rhombus and Kite D) Isosceles Trapezoid, Rhombus and Square

Answers

Answer 1
Answer:

Answer:

C) Square, Rhombus and Kite

Step-by-step explanation:

These are due to the fact that the square has all its equal sides and is 4 sides, so its diagonals will always be perpendicular.

The rhombus also has all its equal sides and are 4 sides so its diagonals will always be perpendicular.

The kite does not have its four equal sides, but its vertices are constructed from its diagonals that cross perpendicularly, so it also meets the perpendicular diagonals

Answer 2
Answer:

The quadrilaterals have perpendicular diagonals are:

C) Square, Rhombus and Kite.

Here, we have,

These are due to the fact that the square has all its equal sides and is 4 sides, so its diagonals will always be perpendicular.

The rhombus also has all its equal sides and are 4 sides so its diagonals will always be perpendicular.

The kite does not have its four equal sides, but its vertices are constructed from its diagonals that cross perpendicularly, so it also meets the perpendicular diagonals.

Diagonals are the part of a shape, in geometry.

In Mathematics , a  diagonal is a line that connects two vertices of a polygon or a solid, whose vertices are not on the same edge. in general, a diagonal is defined as a sloping line or the slant line , that connects to the vertices of a shape. diagonals are defined as lateral shapes that have sides/ edges and corners.

Kite

Rhombus

Square

Hence, The quadrilaterals have perpendicular diagonals are:

Which is the standard form of the equation of a parabola with a focus of (8, 0) and directrix x = –8?

Answers

with a parabola that faces left or right it is
(y-k)²=4p(x-h)

p is distance from directix to vertex which is also the distance from vertex to focus

if it opens to the right, then p is positive
if it opens to the left, then p is negative

so we know that directix is-8 and focus is (8,0)
directix is behind the parabola
so therfor the parabola opens to the right
distance from x=-8 to (8,0) is 16 units
16/2=8
p=8

vertex is 8 units to right of directix or 8 units to the left of focus
(8,0) is focus so vertex is (0,0)


(h,k) is vertex
(y-k)²=4p(x-h)
(y-0)²=4(16)(x-0)
y²=64x

Answers

Answer:

The answer would be A/B=H

Step-by-step explanation:

To get rid of the B that is connected to the H, you would do the opposite of what they used. Meaning since the two were multiplied you would divide them. So, you would take your b and divide it on both sides of the equal sign. B and B cancels each other out so you are left with A/B which equals H.

if you assume that the observations in the sample are independent, what is the smallest value the sample size could be to meet the conditions for this hypothesis test?

Answers

Final answer:

To meet the conditions for a hypothesistest assuming independent observations, the sample size should have at least five successes and failures, and the population should be at least 10 or 20 times the size of the sample.

Explanation:

In order to meet the conditions for a hypothesistest that assumes independentobservations in the sample, the sample size should be such that each sample has at least five successes and five failures. Additionally, the population must be at least 10 or 20 times the size of the sample to avoid over-sampling and incorrect results.
