Answer:

Option A) XY

Step-by-step explanation:

We are given the following information in the question:

Two planes ABCD and EFGH intersect each other as shown in the given figure.

We have to find the line along which the two planes intersect.

1. XY

If we join the points X and Y. Clearly, XY lies in the intersection of the two plane. Both the planes passes through the line XY. Hence, it is the line of intersection for both the planes.

2. DY

The line DY does not lie in the plane EFGH and thus cannot be the line of intersection for both the planes.

3. AX

The line AX does not lie in the plane EFGH and thus cannot be the line of intersection for both the planes.

4. AD

The line AD does not lie in the plane EFGH and thus cannot be the line of intersection for both the planes.

The two planes intersect at line XY

Given that two planes named ABCD and EFGH.

These two planes are intersecting each other as shown in the figure.

By looking the figure it is obvious that two planes are intersecting each other at point X and Y.

Hence, the correct answer is XY

Find the distance between the points (-1,-5) and (-10,7).
Paladinen [302]

Answer:

15 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = (- 1, - 5) and (x₂, y₂ ) = (- 10, 7)

d = \sqrt{(-10+1)^2+(7+5)^2}

   = \sqrt{(-9)^2+12^2}

    = \sqrt{81+144}

    = \sqrt{225}

    = 15 units

#1 - HINT - you are finding the total amount make sure you add the interest you calculate to the original deposit amount
Andreyy89

Answer:

$292.50

Step-by-step explanation:

Equation - A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 2.5%/100 = 0.025 per year.

Solving our equation:

A = 260(1 + (0.025 × 5)) = 292.5

A = $292.50

The total amount accrued, principal plus interest, from simple interest on a principal of $260.00 at a rate of 2.5% per year for 5 years is $292.50.

Question 1= Can Kayla conclude that ∆ABC and ∆EDC are similar? Why or why not?
klasskru [66]
We know that 1 side is 100 and 1 angle is 90 degrees
we would need at least 1 more angle or 1 more side length to say that they are similar

no
but, if we asssume that DCB is a straignt line, then we can say that they are similar


2. if we say taht they are similar then DE=AB, so then 175=DE=AB
